He told his people he would find an honest successor (继承者) from the boys across his country. The boys who were interested were told 1______ they needed to go to the palace and 2______ they should plant their seeds. When the boys arrived, the emperor said, “There is a simple test for you. I’ll give a seed to each of you. You must take it home and carefully plant it in a pot. Give it all possible care and bring the pot to me next year. I will decide 3______ will become my successor.”All the boys did 4______ the emperor told them to do. One boy worried a lot because he found 5______ his seed never turned into a bud. He wondered 6______ he could make the seed grow, but nothing worked. However, most other boys got beautiful plants and some even had flowers. The next year, all the other boys came back and showed the results of their efforts. The poor boy sat alone there without any plant in his pot. The emperor examined each pot and explained 7______ he gave out those seeds. He said slowly, “I gave each of you a seed boiled in water so it couldn’t grow at all. But all of you except this young man raised plants using our own seeds instead of mine. He owns the most valuable thing of competitors. He’ll be my successor because of honesty.” With the words, he gave the boy a big hug. The other boys left there in shame. 七、阅读还原。 Everyone is born with the ability to learn. But whether or not you can do this well depends on your learning habits. Recently, the US carried out similar research. 1____ Creating an interest in what they learn If you are interested in something, your brain is more active and it is also easier for you to pay attention to it for a long time. For example, if they need to learn English and they like music or sports, they can listen to English songs or watch sports programs in English. 2__ Practising and learning from mistakes Good learners think about what they are good at and what they need to practice more. Even if you learn something well, you will forget it if you don’t use it. 3 And they are not afraid of making mistakes. Developing their study skills 4 Good learners know the best way they can study. For example, they take notes by writing key words, or draw mind maps to organize ideas. These skills help them remember better and learn more effectively. 5__ Good learners often ask questions in or after class. They aren’t afraid when they don’t understand something. They know knowledge doesn’t just come from listening quietly-asking questions helps them clear up doubts and learn better. Learning is a lifelong journey because every day brings something new. Everything that you learn becomes a part of you and changes you, so learn wisely and learn well. A．Asking questions B．This way they will not get bored. C．It is not enough to just study hard. D．They prefer to study alone without any help. E．Good learners never make any mistakes in their study. F．Good learners will keep practicing what they have learned. G．It shows successful learners have some good habits in common. 八、语法选择。 I used to feel hopeless and stressful. Last year, 1 mother became seriously ill and had an operation (手术) on her brain. I felt my whole world turn upside down and I didn’t know 2 . I could never know how to deal 3 such tough things until I read “If You Have a Lemon, Make Lemonade (柠檬汁).” “When the wise man 4 a lemon, he says, ‘What lesson can I get from this? How can I improve my situation? How can I turn this lemon into a lemonade?’” the author wrote. I 5 realized what life really is—it’s full of ups and downs, so I need to stay positive all the time. Now when I think of my past, I wish I could have done with things differently. 6 my mother was fighting against her illness, I should have held her hands in mine, telling her things would get much better. Several 7 ago, I took part in a school singing competition. I didn’t win a prize. If I had not read this article, I would certainly have felt upset again. But instead, I smiled after 8 competition. I was happy that at least I had got some stage experience. Life 9 not just full of roses. There are thorns (刺) too, but these thorns help us become brave and strong. When life gives us a lemon, let’s try 10 lemonade. *The word “positive” means feeling confident and sure that sth. good will happen. 1．A．me B．my C．I D．mine 2．A．why I could do B．why could I do C．what I could do D．what could I do 3．A．of B．at C．with D．in 4．A．gives B．gave C．was given D．is given 5．A．normal B．normally C．sudden D．suddenly 6．A．Because B．When C．If D．Although 7．A．weeks B．week C．weeks’ D．week’s 8．A．the B．a C．an D．/ 9．A．are B．is C．am D．be 10．A．to repeat B．repeat C．to make D．make Part 1: Read and Explore Plants might look like they are doing nothing, but in fact they are very busy. And what they’re doing is very “smart”. In the 1980s, two scientists found that plants can “talk” to each other. They planted several tree seedlings (幼苗) in separate pots and put them all inside a clear box. When they tore (撕扯) leaves on one of the young trees, it produced a chemical to try to protect itself. Then, about 36 hours later, the other seedlings made the same chemical. This showed that the hurt tree had sent a signal through the air to the others. Since then, more studies have shown that plants “talk” in a very complex way. For example, they can send different signals when they are hurt by different insects. Their messages can even tell other plants how far away the danger is. What’s more, plants can even learn. A 2014 Australian study used the mimosa (含羞草). This plant is known for curling its leaves when it’s touched. The scientists put many pots of this plant on special racks (架子). They then dropped each plant 15 centimeters down on its rack and repeated this 60 times. At first, the plants curled their leaves, but they soon stopped. They had learned that the drop wouldn’t hurt them. Plants don’t have brains, so how do they learn? Well, plants have a system of tubes (导管) that move water and nutrients (养分) within them. When plants are affected by their environment, they produce certain chemicals. These chemicals move through the tubes to send important messages. This helps the plants change their reactions to the environment. Part 2: Skills Challenge Task 1: Critical Thinking（根据文章内容回答问题） 1.What will plants do to protect themselves when their leaves are torn? ____________________________________________________________________________________________ 2.写出文中能体现植物具备学习能力的一个例子： ____________________________________________________________________________________________ 3.设计一句含有how 引导的宾语从句的英文句子，介绍植物的生存智慧：We want to know ___________________________________________________.

How can I improve my situation? How can I turn this lemon into a lemonade?”可知，作者在读书时突然悟到了生活的真谛。故选D。 6．句意：当我的母亲在与病魔斗争时，我本应该握住她的手，告诉她一切都会好起来的。 Because因为；When在……时候；If如果；Although虽然。根据“…my mother was fighting against her illness, I should have held her hands in mine, telling her things would get much better.”可知，此处使用when引导时间状语从句，表示“在妈妈与疾病作斗争时”。故选B。 7．句意：几周前，我参加了学校举办的歌唱比赛。 weeks周，复数名词；week周，单数名词；weeks’……周的，复数名词所有格；week’s一周的，单数名词所有格。根据“Several…ago”可知，空后无名词，所以空处不使用名词所有格，排除C和D；several修饰复数名词，排除B。故选A。 8．句意：但相反，比赛结束后，我笑了。 the定冠词，表示特指；a不定冠词，表示泛指，用在以辅音音素开头的单词前；an不定冠词，表示泛指，用在以元音音素开头的单词前；/零冠词。根据“a school singing competition”可知，此处特指上文中提到的歌唱比赛，所以用the修饰。故选A。 9．句意：生活不只是充满玫瑰。 are是，主语是第一、三人称复数或you；is是，主语是第三人称单数；am是，主语是I；be是，动词原形。根据“Life…not just full of roses.”可知，句中时态为一般现在时，主语是第三人称单数，所以be动词用is。故选B。 10．句意：当生活给我们一个柠檬，让我们试着做柠檬水。 to repeat重复，动词不定式；repeat重复，动词原形；to make制作，动词不定式；make制作，动词原形。根据“let’s try…lemonade.”和上文“If You Have a Lemon, Make Lemonade (柠檬汁).”可知，此处指制作柠檬水，排除A和B；try to do sth.“尝试做某事”，空处使用to make。故选C。 Part 1: Read and Explore Plants might look like they are doing nothing, but in fact they are very busy.

Since then, more studies have shown that plants “talk” in a very complex way. For example, they can send different signals when they are hurt by different insects. Their messages can even tell other plants how far away the danger is. What’s more, plants can even learn. A 2014 Australian study used the mimosa (含羞草). This plant is known for curling its leaves when it’s touched. The scientists put many pots of this plant on special racks (架子). They then dropped each plant 15 centimeters down on its rack and repeated this 60 times. At first, the plants curled their leaves, but they soon stopped. They had learned that the drop wouldn’t hurt them. Plants don’t have brains, so how do they learn? Well, plants have a system of tubes (导管) that move water and nutrients (养分) within them. When plants are affected by their environment, they produce certain chemicals. These chemicals move through the tubes to send important messages. This helps the plants change their reactions to the environment.
