On the contrary, 9 is a 3 number for Chinese. It means “long” and “long life”. 8 is as 4 as 18 for they sound like “rich” and “certain rich”. I 5 in Europe for a long time, and I find that in many western countries people don’t like the number 13. 6 took me years to look for the reason. Till one of my foreign friends told me that there 7 13 people at the Last Supper with Jesus Christ and then he was killed. That’s 8 it is an unlucky number. They try not 9 this number in many ways. For example, 10 you go into a lift, you will not see the number 13 in it. Many people 11 believe Friday the thirteenth is a very unlucky day. It is usually 12 Friday in November. They are very careful 13 that day such as driving slowly. It is interesting to know how people like or dislike 14 numbers. However, we 15 take it seriously.

However, his family was poor, so he had to drop out when he finished secondary school and help his parents to run the store. It didn’t stop Hua Luogeng from studying maths. He always studied maths while he was taking care of the business. One day, a lady came to the store to buy something. Hua Luogeng lost himself in a maths problem and he didn’t pay attention to the customer. When the customer asked how much she had to pay, he told her the number that he just calculated (计算). The customer gave a loud cry, “Is it that expensive?” The cry pulled him back from his maths world. He found he just made a fool of himself. Then he quickly wrapped (包裹) the thing up and collected the money. After the customer left, Hua Luogeng wanted to continue his calculation, but his draft (草稿) paper was gone. He realized that the piece of paper he just used for wrapping was his draft paper. Hua Luogeng was so nervous and ran after the customer at once. He finally caught up with the lady. The lady was moved and returned it to him. His love for mathematics helped him to overcome many difficulties. He studied by himself and finally he went to Tsinghua University to work as a professor. He also published ten works of maths. Hua Luogeng was a famous mathematician worldwide. He made a great contribution to the development of maths in China. He was praised as “The father of modern Chinese mathematics” and “China’s Einstein”. He has influenced the Chinese a lot. 26．What’s the meaning of “run” in Paragraph 1?

Hua Luogeng lost himself in a maths problem and he didn’t pay attention to the customer.”及“The lady was moved and returned it to him.”可推知，文章举例一次华罗庚沉迷在数学中，导致给一位顾客弄错价格，从而证明华罗庚热爱数学。故选C。 29．细节理解题。根据“Hua Luogeng lost himself in a maths problem”可知，b项“华罗庚全神贯注于一个数学问题。”为顺序1；根据“Then he quickly wrapped (包裹) the thing up…”可知，a项“华罗庚迅速用草稿纸把东西包起来。”为顺序2；根据“He realized that the piece of paper he just used for wrapping was his draft paper.”可知，d项“华罗庚意识到他用草稿纸把东西包起来了。”为顺序3；根据“The lady was moved and returned it to him.”可知，c项“这位女士很感动，并把草稿纸还给了他。”为顺序4，因而正确的顺序为：b-a-d-c。故选B。 30．主旨大意题。通读全文，通过讲述华罗庚热衷于数学学习，最后通过自己努力为中国数学发展做出了巨大的贡献，而且影响了很多中国人，从而告诉我们：只要有决心，没有什么是不可能的。故选D。 B Can you say the meaning of “Zero”? Can you do addition and subtraction (加减法)? Most people can. But do you know bees can do these things too? A study shows that bees have even greater math abilities. After some training, they can know the difference between even numbers (ending in 0, 2, 4, 6 and 8) and odd numbers (ending in 1, 3, 5, 7 and 9). Some Australian scientists put up different cards with an odd or even number of triangles (三角形). They used the numbers 1 to 10. Then they trained the first group of bees to choose odd numbers and the second group to choose even numbers. If a bee flew to the right card, it would get sugar water. If it chose the wrong card, it got bitter (苦的) water. In a short time, all the bees knew what odd numbers or even numbers were. They could fly to the right numbers 80% of the time. After that, the scientists added new cards with the numbers 11 and 12. The bees never saw the numbers in their training before, but they could choose rightly 70% of the time. Surprisingly, the bees even learned odd numbers more quickly than people. How did the bees learn the numbers so fast? Scientists didn’t have a clear idea. But they believe if they find the answer, it will help them build better and faster computers. After all, a bee’s brain is about 86,000 times smaller than ours! 31．How does the passage start? A．By listing facts. B．By giving examples. C．By asking questions. D．By using pictures. 32．Which of the following card should the second group of bees fly to? A．①④ B．②③ C．①② D．③④ 33．Which of the following is TRUE according to the passage? A．Our brains are 8,600 times bigger than bees. B．Bees like bitter water rather than sugar water. C．After training, bees can learn even numbers more quickly than people. D．After training, bees can know the difference between even numbers and odd numbers. 34．What can we learn from the last paragraph? A．Bees have a great ability to learn numbers. B．Bees like odd numbers better than even numbers. C．Scientists know how bees learn numbers. D．Scientists know why bees can tell different numbers. 35．Where can we read this passage in the newspaper? A．Animal World. B．Sports Life. C．Festival Week. D．Beautiful Cities. 【答案】31．C 32．B 33．D 34．A 35．A 【分析】本文是一篇说明文。文章主要讲述了蜜蜂经过训练后可以学会数字并有很强的数学能力的内容。 31． 细节理解题。根据“Can you say the meaning of “Zero”? Can you do addition and subtraction? Most people can. But do you know bees can do these things too?”可知，文章是通过问问题的方式开始的。故选C。 32．细节理解题。根据“the second group to choose even numbers”可知，第二组选择偶数，题干中图②数字2为偶数，图③数字8为偶数，所以②③符合原文。故选B。 33． 细节理解题。根据“After some training, they can know the difference between even numbers and odd numbers.”可知，经过训练蜜蜂可以知道偶数和奇数之间的区别。故选D。 34． 推理判断题。根据最后一段内容可知，蜜蜂的大脑比我们小约86000倍，却能这么快学会数字，可见其有超强的数学能力。选项A“蜜蜂具有很强的学习数字的能力”符合原文内容。故选A。 35． 推理判断题。根据本文所讲述的蜜蜂经过训练后可以学会数字并有很强的数学能力的内容。 我们可以在报纸的动物世界部分读到这篇文章。故选A。 C You may feel that math is difficult and boring. Is it possible that you’ve been looking at math in the wrong way? Numbers are beautiful There is math hidden in beautiful human bodies. Measure the length from your head to your belly button (肚脐) and from your belly button to your feet. The ratio (比例) of these two numbers is always around 0.618. This is the golden ratio, which can be seen everywhere, like in nature, music and paintings. In Chinese poems, we can also see the beauty of numbers. As Li Bai wrote, “My skiff (小船) has left ten thousand mountains far away”, “A thousand miles in one day”—all these numbers show how fast Li Bai traveled and how happy he felt. Curves (曲线) are beautiful “Sine curves” are beautiful. They go towards the two opposite directions on and on without ever ending. When you look at them, you may feel like standing by the sea and watching the waves slowly moving. When listening to music, the sound waves from guitars or pianos are made up of sine curves. “Tangent curve” is like a waterfall, just as Li Bai wrote, “dashing down three thousand feet from on high”. Formulas (公式) are beautiful There are some amazing formulas. In a right-angled triangle, the square of the longest side is equal to the sum of the squares of the other two sides. How amazing! Just as Chinese-American mathematician Chern Shingshen said, “Math is fun!” 36．If the ratio of a thing is around 0.618, ________. A．it is a golden object B．it only happens in human bodies C．it should be something used for math study D．it might bring people a sense of beauty 37．Why does the writer mention Li Bai and his poems in the passage? A．To introduce the topic. B．To support his opinion. C．To share the beauty of Li Bai’s poems. D．To offer advice on learning math. 38．What does a sine curve look like? A． B． C． D． 39．The underlined word “dashing” probably means ________. A．流淌 B．跳跃 C．猛冲 D．闪烁 40．What is the passage mainly about? A．Why math is beautiful and fun. B．Why math is difficult and complex. C．How we can learn math in a right way. D．How math helps us live a better life. 【答案】36．D 37．B 38．A 39．C 40．A 【导语】本文是一篇说明文，介绍了数学的美丽和趣味性，通过举例说明数学在人体比例、诗歌、曲线和公式中的体现，强调了数学并非枯燥无味，而是充满美感和乐趣。 36．细节理解题。根据“The ratio (比例) of these two numbers is always around 0.618. This is the golden ratio, which can be seen everywhere, like in nature, music and paintings.”可知，如果一个事物的比例大约是0.618，那么它可能是黄金比例，这种比例在自然、音乐和绘画中随处可见，能给人带来美感。故选D。 37．推理判断题。根据“In Chinese poems, we can also see the beauty of numbers. As Li Bai wrote, ‘My skiff (小船) has left ten thousand mountains far away’, ‘A thousand miles in one day’—all these numbers show how fast Li Bai traveled and how happy he felt.”可知，作者提到李白和他的诗是为了支持他的观点，即数字中隐藏着美。故选B。 38．细节理解题。根据“ ‘Sine curves’ are beautiful. They go towards the two opposite directions on and on without ever ending. When you look at them, you may feel like standing by the sea and watching the waves slowly moving.”可知，正弦曲线是美丽的，它们朝着两个相反的方向不断延伸，永无止境。当你看着它们时，你可能会觉得自己站在海边，看着海浪慢慢移动。因此，正弦曲线的图像应该是像海浪一样起伏的，选项A的图像最符合描述。故选A。 39．词句猜测题。根据“ ‘Tangent curve’ is like a waterfall, just as Li Bai wrote, ‘dashing down three thousand feet from on high’.”可知，“切线曲线”就像瀑布一样，正如李白所写的那样，“从高处猛冲下来三千尺”。因此，“dashing”在这里的意思是“猛冲”。故选C。 40．主旨大意题。根据文章内容可知，本文主要讲述了数学中的美，包括数字的美、曲线的美和公式的美，以及数学如何带来乐趣。因此，文章的主要内容是为什么数学是美丽和有趣的。故选A。 四、阅读还原（本大题共5小题，每小题1分，满分5分） 请阅读下面的短文，并从文后的六个选项中选择五个还原到原文中，使原文意思完整、连贯。 Do you love maths? 41 Fun activities helped students fall in love with maths!

This number seems common, but it is the most amazing number in the w 51 . Why? Let’s look at a few facts about this number. First, get the number multiplied (相乘) by 1 to 6 and all the results are amazing because they are made up of the same numbers but in different orders. For example, 142857 multiplied by 2 is 285714 while 142857 multiplied by 6 is 857142. S 52 , if it is multiplied by 7 and we get a more amazing number 999999. Third, the number is multiplied by i 53 and we can get a super large number 20408122449. However, when we a 54 the front five numbers to the back six numbers we get e____55_____the same number 142857 again. Is it amazing? In fact, people found this mysterious (神秘的) number inside the pyramids (金字塔) of Egypt. People also discovered the number is linked to the days of a week. So you see, nature is really amazing. And we can learn a lot from it. 【答案】51．(w)orld 52．(S)econd 53．(i)tself 54．(a)dd 55．(e)xactly 【导语】本文介绍了一个非常神奇和有趣的数字——142857。这个数字看似普通，但经过一系列的数学运算后，展现出了一系列神奇的特性。 51．句意：这个数字看起来很普通，但它是世界上最神奇的数字。根据“but it is the most amazing number in the”及首字母可知，它是世界上最神奇的数字，in the world“世界上”。故填(w)orld。 52．句意：第二，这串数字乘以7我们会得到更神奇的数字999999。根据“First”可知，此处介绍的是第二个神奇之处，second“第二”符合。故填(S)econd。 53．句意：第三，这个数字乘以它本身，我们会得到一个超级大数字20408122449。根据“the number is multiplied by ... and we can get a super large number 20408122449.”可知，142857乘以它本身才可以得到20408122449，itself“它本身”符合。故填(i)tself。 54．句意：然而，当我们把前面的五个数字加到后面的六个数字时，我们又得到了同样的数字142857。根据“when we ... the front five numbers to the back six numbers we get the same number 142857 again.”可知，是将20408122449的前五个数字和后六个数字加起来得到142857，add“加”符合，时态为一般现在时，主语是we，谓语动词用原形。故填(a)dd。 55．句意：…… 会再次得到恰好相同的数字 142857。"exactly" 意为 “精确地、恰好”，强调结果与原数字完全一致，符合 “神奇” 的描述。故填(e)xactly。 B(语法填空) 阅读下面语篇，在空白处填入适当的单词或括号内单词的适当形式，必要时可加助动词或情态动词。 Zu Chongzhi was one of the 56 (great) mathematicians (数学家) in ancient China.

Yi and other workmen then 21 the wall. The work took many years. When they 22 finished building the wall, there was one brick left. Yi put that final brick on the wall. “Aha!” said the emperor. “You are wrong! There is one brick left.” “I am not wrong,” said Yi. “This brick is a magic brick. If you 23 it, the whole wall will fall down!” “Why should I believe you?” asked the emperor. “Move it and see what will happen,” said Yi. The emperor was 24 that the wall would fall, so he left the brick on the wall. Then he kept his   25 . He invited Yi to live in his palace.

However, his family was poor, so he had to drop out when he finished secondary school and help his parents to run the store. It didn’t stop Hua Luogeng from studying maths. He always studied maths while he was taking care of the business. One day, a lady came to the store to buy something. Hua Luogeng lost himself in a maths problem and he didn’t pay attention to the customer. When the customer asked how much she had to pay, he told her the number that he just calculated (计算). The customer gave a loud cry, “Is it that expensive?” The cry pulled him back from his maths world. He found he just made a fool of himself. Then he quickly wrapped (包裹) the thing up and collected the money. After the customer left, Hua Luogeng wanted to continue his calculation, but his draft (草稿) paper was gone. He realized that the piece of paper he just used for wrapping was his draft paper. Hua Luogeng was so nervous and ran after the customer at once. He finally caught up with the lady. The lady was moved and returned it to him. His love for mathematics helped him to overcome many difficulties. He studied by himself and finally he went to Tsinghua University to work as a professor. He also published ten works of maths. Hua Luogeng was a famous mathematician worldwide. He made a great contribution to the development of maths in China. He was praised as “The father of modern Chinese mathematics” and “China’s Einstein”. He has influenced the Chinese a lot. 26．What’s the meaning of “run” in Paragraph 1? A．奔跑 B．行使 C．参赛 D．经营 27．Why did Hua Luogeng leave school when he was young? A．Because he didn’t like studying. B．Because he had to help his parents. C．Because he had received enough education. D．Because he couldn’t afford to go to school. 28．How does the text show us that Hua Luogeng loved maths? A．By offering ideas. B．By asking questions. C．By giving an example. D．By listing numbers. 29．Which of the following is the right order according to the text? a. Hua Luogeng quickly wrapped the thing up with the draft paper. b. Hua Luogeng gave all his attention to a maths problem. c. The lady was moyed and returned the draft paper to him. d. Hua Luogeng realized he used his dralt paper to wrap up the thing. A．a-b-c-d B．b-a-d-c C．b-c-a-d D．a-c-d-b 30．What can we learn from the text? A．Success comes easy. B．One is never too old to learn. C．Behind bad luck comes good luck. D．Nothing is impossible for a willing heart. B Can you say the meaning of “Zero”? Can you do addition and subtraction (加减法)? Most people can. But do you know bees can do these things too? A study shows that bees have even greater math abilities. After some training, they can know the difference between even numbers (ending in 0, 2, 4, 6 and 8) and odd numbers (ending in 1, 3, 5, 7 and 9). Some Australian scientists put up different cards with an odd or even number of triangles (三角形). They used the numbers 1 to 10. Then they trained the first group of bees to choose odd numbers and the second group to choose even numbers. If a bee flew to the right card, it would get sugar water. If it chose the wrong card, it got bitter (苦的) water. In a short time, all the bees knew what odd numbers or even numbers were. They could fly to the right numbers 80% of the time. After that, the scientists added new cards with the numbers 11 and 12. The bees never saw the numbers in their training before, but they could choose rightly 70% of the time. Surprisingly, the bees even learned odd numbers more quickly than people. How did the bees learn the numbers so fast? Scientists didn’t have a clear idea. But they believe if they find the answer, it will help them build better and faster computers. After all, a bee’s brain is about 86,000 times smaller than ours! 31．How does the passage start? A．By listing facts. B．By giving examples. C．By asking questions. D．By using pictures. 32．Which of the following card should the second group of bees fly to? A．①④ B．②③ C．①② D．③④ 33．Which of the following is TRUE according to the passage? A．Our brains are 8,600 times bigger than bees. B．Bees like bitter water rather than sugar water. C．After training, bees can learn even numbers more quickly than people. D．After training, bees can know the difference between even numbers and odd numbers. 34．What can we learn from the last paragraph? A．Bees have a great ability to learn numbers. B．Bees like odd numbers better than even numbers. C．Scientists know how bees learn numbers. D．Scientists know why bees can tell different numbers. 35．Where can we read this passage in the newspaper? A．Animal World. B．Sports Life. C．Festival Week. D．Beautiful Cities. C You may feel that math is difficult and boring. Is it possible that you’ve been looking at math in the wrong way? Numbers are beautiful There is math hidden in beautiful human bodies. Measure the length from your head to your belly button (肚脐) and from your belly button to your feet. The ratio (比例) of these two numbers is always around 0.618. This is the golden ratio, which can be seen everywhere, like in nature, music and paintings. In Chinese poems, we can also see the beauty of numbers. As Li Bai wrote, “My skiff (小船) has left ten thousand mountains far away”, “A thousand miles in one day”—all these numbers show how fast Li Bai traveled and how happy he felt. Curves (曲线) are beautiful “Sine curves” are beautiful. They go towards the two opposite directions on and on without ever ending. When you look at them, you may feel like standing by the sea and watching the waves slowly moving. When listening to music, the sound waves from guitars or pianos are made up of sine curves. “Tangent curve” is like a waterfall, just as Li Bai wrote, “dashing down three thousand feet from on high”. Formulas (公式) are beautiful There are some amazing formulas. In a right-angled triangle, the square of the longest side is equal to the sum of the squares of the other two sides. How amazing! Just as Chinese-American mathematician Chern Shingshen said, “Math is fun!” 36．If the ratio of a thing is around 0.618, ________. A．it is a golden object B．it only happens in human bodies C．it should be something used for math study D．it might bring people a sense of beauty 37．Why does the writer mention Li Bai and his poems in the passage? A．To introduce the topic. B．To support his opinion. C．To share the beauty of Li Bai’s poems. D．To offer advice on learning math. 38．What does a sine curve look like? A． B． C． D． 39．The underlined word “dashing” probably means ________. A．流淌 B．跳跃 C．猛冲 D．闪烁 40．What is the passage mainly about? A．Why math is beautiful and fun. B．Why math is difficult and complex. C．How we can learn math in a right way. D．How math helps us live a better life. 四、阅读还原（本大题共5小题，每小题1分，满分5分） 请阅读下面的短文，并从文后的六个选项中选择五个还原到原文中，使原文意思完整、连贯。 Do you love maths? 41 Fun activities helped students fall in love with maths! On the first day, students put on plays and we watched some of them. My favorite play was about Hua Luogeng, a Chinese mathematician (数学家). Three students played Hua at three different ages. 42 The second day was the most interesting. Some students made rocket models with plastic (塑料的) bottles and launched them on the playground. 43 The most successful one flew as high as the second floor of the teaching building. 44 Thy showed us some advanced equipment (先进的装备) and did experiments with us. For example, we made a small water-cleaning system. It turned dirty water into clean water! After finishing the experiment, I felt the magic of science. 45 Students are already looking forward to next year’s festival! A．The school invited some college students on the third day.

However, his family was poor, so he had to drop out when he finished secondary school and help his parents to run the store. It didn’t stop Hua Luogeng from studying maths. He always studied maths while he was taking care of the business. One day, a lady came to the store to buy something. Hua Luogeng lost himself in a maths problem and he didn’t pay attention to the customer. When the customer asked how much she had to pay, he told her the number that he just calculated (计算). The customer gave a loud cry, “Is it that expensive?” The cry pulled him back from his maths world. He found he just made a fool of himself. Then he quickly wrapped (包裹) the thing up and collected the money. After the customer left, Hua Luogeng wanted to continue his calculation, but his draft (草稿) paper was gone. He realized that the piece of paper he just used for wrapping was his draft paper. Hua Luogeng was so nervous and ran after the customer at once. He finally caught up with the lady. The lady was moved and returned it to him. His love for mathematics helped him to overcome many difficulties. He studied by himself and finally he went to Tsinghua University to work as a professor. He also published ten works of maths. Hua Luogeng was a famous mathematician worldwide. He made a great contribution to the development of maths in China. He was praised as “The father of modern Chinese mathematics” and “China’s Einstein”. He has influenced the Chinese a lot. 26．What’s the meaning of “run” in Paragraph 1? A．奔跑 B．行使 C．参赛 D．经营 27．Why did Hua Luogeng leave school when he was young? A．Because he didn’t like studying. B．Because he had to help his parents. C．Because he had received enough education. D．Because he couldn’t afford to go to school. 28．How does the text show us that Hua Luogeng loved maths? A．By offering ideas. B．By asking questions. C．By giving an example. D．By listing numbers. 29．Which of the following is the right order according to the text? a. Hua Luogeng quickly wrapped the thing up with the draft paper. b. Hua Luogeng gave all his attention to a maths problem. c. The lady was moyed and returned the draft paper to him. d. Hua Luogeng realized he used his dralt paper to wrap up the thing. A．a-b-c-d B．b-a-d-c C．b-c-a-d D．a-c-d-b 30．What can we learn from the text? A．Success comes easy. B．One is never too old to learn. C．Behind bad luck comes good luck. D．Nothing is impossible for a willing heart. B Can you say the meaning of “Zero”? Can you do addition and subtraction (加减法)? Most people can. But do you know bees can do these things too? A study shows that bees have even greater math abilities. After some training, they can know the difference between even numbers (ending in 0, 2, 4, 6 and 8) and odd numbers (ending in 1, 3, 5, 7 and 9). Some Australian scientists put up different cards with an odd or even number of triangles (三角形). They used the numbers 1 to 10. Then they trained the first group of bees to choose odd numbers and the second group to choose even numbers. If a bee flew to the right card, it would get sugar water. If it chose the wrong card, it got bitter (苦的) water. In a short time, all the bees knew what odd numbers or even numbers were. They could fly to the right numbers 80% of the time. After that, the scientists added new cards with the numbers 11 and 12. The bees never saw the numbers in their training before, but they could choose rightly 70% of the time. Surprisingly, the bees even learned odd numbers more quickly than people. How did the bees learn the numbers so fast? Scientists didn’t have a clear idea. But they believe if they find the answer, it will help them build better and faster computers. After all, a bee’s brain is about 86,000 times smaller than ours! 31．How does the passage start? A．By listing facts. B．By giving examples. C．By asking questions. D．By using pictures. 32．Which of the following card should the second group of bees fly to? A．①④ B．②③ C．①② D．③④ 33．Which of the following is TRUE according to the passage? A．Our brains are 8,600 times bigger than bees. B．Bees like bitter water rather than sugar water. C．After training, bees can learn even numbers more quickly than people. D．After training, bees can know the difference between even numbers and odd numbers. 34．What can we learn from the last paragraph? A．Bees have a great ability to learn numbers. B．Bees like odd numbers better than even numbers. C．Scientists know how bees learn numbers. D．Scientists know why bees can tell different numbers. 35．Where can we read this passage in the newspaper? A．Animal World. B．Sports Life. C．Festival Week. D．Beautiful Cities. C You may feel that math is difficult and boring. Is it possible that you’ve been looking at math in the wrong way? Numbers are beautiful There is math hidden in beautiful human bodies. Measure the length from your head to your belly button (肚脐) and from your belly button to your feet. The ratio (比例) of these two numbers is always around 0.618. This is the golden ratio, which can be seen everywhere, like in nature, music and paintings. In Chinese poems, we can also see the beauty of numbers. As Li Bai wrote, “My skiff (小船) has left ten thousand mountains far away”, “A thousand miles in one day”—all these numbers show how fast Li Bai traveled and how happy he felt. Curves (曲线) are beautiful “Sine curves” are beautiful. They go towards the two opposite directions on and on without ever ending. When you look at them, you may feel like standing by the sea and watching the waves slowly moving. When listening to music, the sound waves from guitars or pianos are made up of sine curves. “Tangent curve” is like a waterfall, just as Li Bai wrote, “dashing down three thousand feet from on high”. Formulas (公式) are beautiful There are some amazing formulas. In a right-angled triangle, the square of the longest side is equal to the sum of the squares of the other two sides. How amazing! Just as Chinese-American mathematician Chern Shingshen said, “Math is fun!” 36．If the ratio of a thing is around 0.618, ________. A．it is a golden object B．it only happens in human bodies C．it should be something used for math study D．it might bring people a sense of beauty 37．Why does the writer mention Li Bai and his poems in the passage? A．To introduce the topic. B．To support his opinion. C．To share the beauty of Li Bai’s poems. D．To offer advice on learning math. 38．What does a sine curve look like? A． B． C． D． 39．The underlined word “dashing” probably means ________. A．流淌 B．跳跃 C．猛冲 D．闪烁 40．What is the passage mainly about? A．Why math is beautiful and fun. B．Why math is difficult and complex. C．How we can learn math in a right way. D．How math helps us live a better life. 四、阅读还原（本大题共5小题，每小题1分，满分5分） 请阅读下面的短文，并从文后的六个选项中选择五个还原到原文中，使原文意思完整、连贯。 Do you love maths? 41 Fun activities helped students fall in love with maths!
