Things like losing a job or someone we love can surprise us and make us feel sad. At first,we might not want change and feel like we've lost something important. But if we deal with it in the right way,we can accept change and even do well because of it. 16 One good way to deal with change is to admit （承认） how we feel and let others know. When something sad happens,it's okay to feel sad. Talking about it with friends or family can make us feel better. We can also think about why we feel bad and what might happen because of the change. Asking ourselves questions can help us see if our worries make sense. It's good to remember that change can sometimes lead us to find what we really want in life. Even if it seems bad at first,it can help us find a new direction. For example,if we lose a job,we might find a new job that we like even more or we might get the chance to follow a dream we had. We need to do things to really accept change. We can keep working on our goals,try new things,or spend time with people who help us feel better. Doing things can help us not think about our worries so much. It can also help us make a better future for ourselves. It's also important to think about the future and find ways to keep going. This could mean looking for a new job,going on a trip,or making new goals for ourselves. Looking ahead can help us deal with the past and see it as something that had to happen so we can move forward. Finally,we can choose to use those we are very good at to make the world better. This way of thinking helps us accept change and even change things for the better. 1.________ 2.___________ 3.________ 4._____________ 5.__________ feelings reasonable chances focus / mind strengths 21 B.任务型阅读。根据短文内容，按要求回答问题。 There are many famous hoaxes in the world. Let's take a look at three of them. A THINKING MACHINE In 1769,long before computers were invented,a man from Hungary built a wonderful machine that could play chess very well. It pleased people all over Europe and beat nearly everyone who played chess with it. For many years,many people believed that it was truly a thinking machine. 22 About 85 years later,the secret was finally revealed （揭示）.There was a man hiding inside the machine all the time,who was clearly very good at playing chess! ZOO ESCAPE（逃脱） On November 9,1874,a New York newspaper ran a shocking story on its front page. It said that all the animals in the Central Park Zoo had escaped and were running around the city. It said the police were working to save people,but 27 people had already been killed,and 200 people were hurt. Many people in New York 23 were very scared. But it was all just a hoax. The story was made up by Thomas Connery,an editor （编辑） at The Herald,who wanted to make more people pay attention to the problem that the cages （笼子） in the zoo were in poor condition. ROSIE,THE RUNNER 24 The first woman to cross the finish line of the 1980 Boston Marathon （马拉松） was 23-year-old Rosie Ruiz. However,as she received her prize,people started to doubt that. She didn't seem to be tired at all. What's more,none of the other runners remembered seeing her in the race. Later,it turned out that she had run only half a mile （about 805 meters） and taken the train for the rest of the race! Her prize was taken away,of course. 25 6.When did people find the truth about the thinking machine? _______________________________________________________ They found the truth about the thinking machine in 1854. 7.Why did Thomas create the hoax?（no more than 12 words） _____________________________________________________________ To draw attention to the poor condition of the cages in the zoo. 8.What do you think of Rosie's behavior （行为）? ________________________ It's dishonest and unfair. 9.Why does the writer write the passage? _______________________________________ To introduce three famous hoaxes to us. 26 10.What can we learn from the passage to avoid being tricked by misinformation? _______________________________________________________________ ________________________________ When we're told some information,we should question it,think twice and dig deeper.（答案合理即可） 27 四、书面表达。 假如你是王迅，昨天你收到你的美国朋友杰克（Jack）的电子邮件。 请你根据邮件内容，给他回复一封电子邮件。 要求：100词左右（邮件的开头和结尾已给出，不计入总词数）。 28 Dear Wang Xun, Today,I was eating in the restaurant and a man sitting in front of me ate the potato chips in my plate. I didn't say anything although I wasn't very happy. After finishing sharing these chips,the waiter served me a plate of potato chips and wished me a good meal. I didn't realize I had eaten the man's potato chips until then. I said sorry to the man and felt really embarrassed. Do you have such an embarrassing experience? Write me back. Yours, Jack 29 Dear Jack, Here I'd like to tell you about my embarrassing experience. _______________________________________________________________ _______________________________________________________________ _______________________________________________________________ _______________________________________________________________ _______________________________________________________________ _______________________________________________________________ ________________________________________________________ Once,I invited my friend,Peggy,to dinner.

Receiving the order,Gun led his team to build dikes （堤坝） to keep back the water,but he . .4. ..Then Shun,the next emperor,ordered Gun's son Yu to . .5. . with the work after Gun died. Yu accepted the work and found that it was much more difficult than he had thought. But he fought against the great flood . .6. ..For thirteen years,he put himself to his work.

It's not real snow,of course — it's catkins （飞絮） from willows and poplar trees in spring. For some people,this “snow” is not welcomed. Catkins can make people's noses,eyes,and skin uncomfortable. In spring,the female （雌性的） trees grow lots of flowers. When these flowers finish growing,they produce cotton-like seeds that spread through the air. 44 Luckily,scientists have found many ways to control catkins. Doing “gender （性别） change surgery” on willow and poplar trees is one of them. People cut off the branches （ ） of female trees and replace （替换） them with branches from male （雄性的） trees. This cuts down the number of catkins. However,this way is slow and expensive. A skilled worker can do the “surgery” on less than ten trees a day. Scientists in Wuxi,Jiangsu,use special injections （注射剂） to reduce the number of catkins on trees. These injections make the trees mainly use their energy to grow bigger and get more leaves,not to reproduce and make catkins. Xu Qinming,an expert in Wuxi,told Science and Technology Daily that this method is safe for the trees. However,the trees need to get injections every year to keep the catkin numbers under control. Other than injections,the trees can take “medicine”.This medicine can be sprayed （喷洒） onto the trees before the catkins form,which can quickly reduce catkin numbers. Still,people need to be careful about how much of the medicine they use and when they use it,or they might hurt the environment. 1.Which picture shows the problem mentioned in the first three paragraphs?( ) B A. B. C. 2.What does the “gender change surgery” refer to?( ) C A.Planting more male trees. B.Cutting off the branches of female trees. C.Changing the gender of the branches. 47 3.How many ways are introduced to deal with catkins?( ) A A.Three. B.Four. C.Five. 4.What's the disadvantage of using injections according to the passage?( ) B A.It is slow and expensive. B.Trees need to be injected every year. C.It needs many skilled workers to do it. 48 5.What's the main idea of the passage?( ) C A.How to protect willow and poplar trees. B.How to tell male and female trees apart. C.How to control catkins with new technology. 49 Unit 13 We're trying to save the earth! 第2课时 Section A（2a-2d） 50 一、从括号内选出一个符合语意的单词或词组，并用其正确形式完 成句子。 1.Eating too much sugar can lead ___（for;in;to） health problems. to 2.— The skirt looks nice on you.

As the leader of the recycling club,Scott was thinking about new activities to encourage other students to become more active in recycling. Scott went home and looked online,hoping to find ideas for events the club could organize at school. During his research,he learned that the number of electronic waste,or e-waste,is 63 increasing rapidly. Scott was upset with himself for it. At that moment,he began to develop a plan. “There is a special project I want us to work on this term,” Scott announced at the recycling club meeting the next day.“We have all heard about e-waste,but recently I learned about the bad effects it's having on our environment.” He went on to tell the club members that he wanted them to organize an e-waste drive — a day when students and their families could drop off unwanted electronics to be recycled.“Now let's get to work!” For several weeks,the recycling club was busy preparing for the upcoming e-waste drive,or e-drive as it was soon called. The big day finally arrived,and Scott was nervous. He and the other members arrived at school early to make sure that everything would go smoothly. Everyone hoped that students of the school would take part in the event. It wasn't long before the first cars pulled into the school parking lot. After a while,more people arrived. Phones,TV sets,computers and keyboards soon began piling up （堆积）. At the end of the event,Scott heard someone suggest that the school should have an e-drive event every term. Scott smiled,realizing that a simple action could truly have a lasting influence. 1.Why did Scott feel upset according to the second paragraph? _______________________________________________________________ ____ Because he learned that the number of e-waste is increasing rapidly. 2.How did Scott probably feel after the e-drive? __________________________________________________ He probably felt happy and proud after the e-drive. 3.What do you think of Scott's e-drive event?
