You know pollution is bad for our health. Mark: 1 ? Jack: Good question! In fact, we can do many things to stop pollution in our daily life. Mark: 2 ? Jack: Of course I can tell you some ways.

It is something called the water cycle (循环)． There is always water in the air, but you can’t always 2 it. It’s called water vapor. The 3 heats up water in rivers, lakes and oceans. The water 4 water vapor. It goes into the air. High in the sky, it is 5 at first. When water vapor gets cold, it becomes 6 again. You can see this 7 when you have a cold drink on a warm day. Water is on the outside of the glass. Does the glass leak (漏)? No. Water vapor in the air turns into water when it touches (接触) the cold 8 . Millions of water drops come together in the sky. They 9 clouds. Wind moves clouds. And the water vapor in clouds cools off and changes to water. Then the water 10 onto the Earth. Rain falls back into the oceans, lakes and rivers.

But in September, there was a shaking (摇晃) under our feet for more than a week. Now, scientists find that it is because of global (全球) warming. The shaking came from Earth’s crust, it is the shell of earth, just like the skin of an apple. It lasted for nine days and went across the whole world. The study shows that it started in eastern Greenland. Because of global warming, at the foot of a mountain, the ice got thin. It couldn’t carry the rocks (岩石) on it, and the 1,200-meter-high mountain came into small pieces. The rocks all fell down into the sea. This made a really big tsunami (海啸). It was about 110 meters high. Over the next few days, the water moved back and ahead, hitting the cliffs (崖壁). Luckily, nobody was hurt. But the scientists believe more things like this will take place because the world is getting warmer. 1．What does the underlined “it” refer to (指) in Paragraph 1? A．Hot weather on Earth. B．The ground under our feet. C．Changes in Earth’s crust. D．The shaking of the ground. 2．Which of the following is TRUE according to the passage? A．The shaking came from the shell of earth. B．The ice got thin at the top of a mountain. C．The 110-meter-high mountain became small pieces. D．The shaking lasted for less than seven days. 3．How did the worldwide shaking happen? A．①→②→③→④ B．①→③→②→④ C．②→④→①→③ D．②→③→④→① 4．What can we learn from the last paragraph? A．Global warming will seldom bring shakings. B．The scientists believe more people will get hurt. C．The scientists believe they can stop the shaking. D．Global warming will keep changing the world. (B) The Yangtze River is the longest river in China. It is the home to over 400 species (物种) like the Chinese sturgeon (中华鲟). The Chinese sturgeon is one of the largest fish in the world and it’s long. A Chinese sturgeon can grow up to about 5m long, over 500kg and live to be 40 years old. They’ve lived on the earth for about 140,000,000 years, so people call them a “living fossil (化石)”. The Chinese sturgeon was common in the river before. However, it’s in danger now. Fishing too much in the 1970s made the species fewer and fewer. And in 1981, the building of the Gezhouba Dam put the sturgeon into two groups. The two groups could not get together. As a result, the species became even fewer. So the help for the Chinese sturgeon is very necessary. Luckily, China already took action. On May 14th. Shanghai passed a new rule to help the Chinese sturgeon. This was the first rule in the country to help one fish in danger. From January 2020, the country also started to stop people from fishing in the Yangtze River. It will last (持续) for ten years. We believe the Chinese sturgeon will become more and more. We should also play a part in saving the species in danger. 1．From Paragraph (段落) 1, we can know about the common ________ of the Chinese sturgeon. A．food B．age C．habit D．color 2．What does “took action” mean in Chinese? A．实现梦想 B．拒绝改变 C．放弃希望 D．采取行动 3．Which of the following is TRUE according to the passage? A．The Chinese sturgeon is common now. B．People call the Chinese sturgeon a living fossil. C．There are less than 400 species in the Yangtze River. D．Beijing passed a new rule to help the Chinese sturgeon. 4．In the last paragraph, the writer wants us to ________. A．start to go fishing B．make a new rule C．save the Chinese sturgeon D．clean the Yangtze River 2 / 2 学科网（北京）股份有限公司 $$ Unit 8 Time on the earth 一、英汉互译 ① according to ___________ ②4.6 billion years ______________ ③在...底部 ____________ ④ start to do ______________ ⑤ the age of dinosaurs ____________ ⑥ 出生，生育 ______________ 【答案】 1.根据 2.46亿年 3.at the bottom of 4. 开始做.. 5.恐龙时代 6.give birth to 2、 单项选择 1．The Tom and Jerry series first appeared on screen 　　　 1940.

C．The scientists believe they can stop the shaking. D．Global warming will keep changing the world. 【答案】1．D 2．A 3．B 4．D 【解析】本文是一篇说明文。文章主要讲述因全球变暖，格陵兰东部山脚下冰层变薄，致使高山崩塌成小块岩石坠入海中引发海啸，进而造成全球范围的地壳震动，且科学家认为随着全球变暖会有更多类似情况发生。 1．词句猜测题。根据“Maybe we did not feel it at that time. But in September, there was a shaking under our feet for more than a week. Now, scientists find that it is because of global warming”，可推理出这里的“it”指的是前面提到的“a shaking”，即地面的摇晃。故选D。 2．细节理解题。根据“The shaking came from Earth’s crust, it is the shell of earth”可知，摇晃来自地壳，地壳就是地球的外壳。故选A。 3．细节理解题。图示的正确顺序应是，“at the foot of a mountain, the ice got thin”①山上冰变薄；“It couldn’t carry the rocks (岩石) on it, and the 1,200-meter-high mountain came into small pieces.”③不能承受岩石重量，山崩；“The rocks all fell down into the sea. This made a really big tsunami (海啸).”②然后形成巨大海啸；Over the next few days, the water moved back and ahead, hitting the cliffs (崖壁).④海水前后冲撞。根据文章内容，正确顺序是：①→③→②→④。故选B。 4．细节理解题。根据“the scientists believe more things like this will take place because the world is getting warmer”表明全球变暖会持续引发各种类似的变化，也就意味着全球变暖将持续改变世界，故选D。 (B) The Yangtze River is the longest river in China. It is the home to over 400 species (物种) like the Chinese sturgeon (中华鲟). The Chinese sturgeon is one of the largest fish in the world and it’s long. A Chinese sturgeon can grow up to about 5m long, over 500kg and live to be 40 years old. They’ve lived on the earth for about 140,000,000 years, so people call them a “living fossil (化石)”. The Chinese sturgeon was common in the river before. However, it’s in danger now. Fishing too much in the 1970s made the species fewer and fewer. And in 1981, the building of the Gezhouba Dam put the sturgeon into two groups. The two groups could not get together. As a result, the species became even fewer. So the help for the Chinese sturgeon is very necessary. Luckily, China already took action. On May 14th. Shanghai passed a new rule to help the Chinese sturgeon. This was the first rule in the country to help one fish in danger. From January 2020, the country also started to stop people from fishing in the Yangtze River. It will last (持续) for ten years. We believe the Chinese sturgeon will become more and more. We should also play a part in saving the species in danger. 1．From Paragraph (段落) 1, we can know about the common ________ of the Chinese sturgeon. A．food B．age C．habit D．color 2．What does “took action” mean in Chinese? A．实现梦想 B．拒绝改变 C．放弃希望 D．采取行动 3．Which of the following is TRUE according to the passage? A．The Chinese sturgeon is common now. B．People call the Chinese sturgeon a living fossil. C．There are less than 400 species in the Yangtze River. D．Beijing passed a new rule to help the Chinese sturgeon. 4．In the last paragraph, the writer wants us to ________. A．start to go fishing B．make a new rule C．save the Chinese sturgeon D．clean the Yangtze River 【答案】1．B 2．D 3．B 4．C 【解析】本文介绍了长江中的中华鲟这一濒危物种，其因过度捕鱼和葛洲坝修建导致数量减少，中国已采取行动来保护中华鲟。 1．细节理解题。根据“A Chinese sturgeon can grow up to about 5m long, over 500kg and live to be 40 years old”可知可以知道中华鲟的年龄。故选B。 2．词义猜测题。根据“Luckily, China already took action. On May 14th. Shanghai passed a new rule to help the Chinese sturgeon”可知海通过了一项帮助中华鲟的新规定，可见中国已经采取行动保护中华鲟，故此处划线部分意为“采取行动”。故选D。 3．细节理解题。根据“so people call them a ‘living fossil (化石)’.”可知中华鲟被成为“活化石”。故选B。 4．推理判断题。根据“We believe the Chinese sturgeon will become more and more. We should also play a part in saving the species in danger.”可知我们也应该在拯救濒危物种方面发挥作用，所以作者想要我们拯救中华鲟。故选C。 2 / 2 学科网（北京）股份有限公司 $$
