单元限时练(二)　A卷 (限时 40分钟) [对应学生用书P183] Ⅰ.阅读理解 A A small piece of fish each day may keep the heart doctor away.That's the finding of a study of Dutchmen in which deaths from heart disease were more than 50 percent lower among those who consumed at least an ounce of salt water fish per day compared to those who never ate fish. The Dutch research is one of three human studies that give strong scientific support to the long­held belief that eating fish can provide health benefits, particularly to the heart.Heart disease is the number­one killer in the United States, with more than 550，000 deaths occurring from heart attacks each year.But previous research has shown that the level of heart disease is lower in cultures that consume more fish than Americans do.There are fewer heart disease deaths, for example, among the Eskimos of Greenland, who consume about 14 ounces of fish a day, and among the Japanese, whose daily fish consumption average more than 3 ounces. For 20 years, the Dutch study followed 852 middleaged men, 20 percent of whom ate no fish.At the start of the study, average fish consumption was about two­thirds of an ounce each day, with more men eating lean fish than fatty fish. During the next two decades, 78 of the men died from heart disease.The fewest deaths were among the group who regularly ate fish, even at levels far lower than those of the Japanese or Eskimos. This relationship was true regardless of other factors such as age，high blood pressure, or blood cholesterol (胆固醇) levels.

C　[文章出处题。本文主要介绍了吃鱼和健康的关系。] B I'd been thinking of taking a course on scuba­diving(水肺潜水) for months, but wasn't sure because I was afraid of snakes—sea snakes. Just thinking about it made me sick. But then, I wanted to know why people loved it so much. They all said that under the sea was like a totally different world, yet a beautiful one. And because of that, I decided to take the risk and try to face my fear. So, after taking a private course from my diving instructor, Mbak Vita, I went to Sepa Island with her, to take the final exam. First dive, 12 meters in depth. “What am I doing？” I asked myself. “What if something bad happened？” I tried hard not to panic and told myself to keep a good thought, “It's going to be a wonderful experience. Just do it！” Then I went down. My heart beat fast and my ears hurt as I went deeper. I followed Vita's instructions closely until I felt comfortable to explore the sea. Suddenly all around me was green. It felt like I was living in a green world! I saw some corals(珊瑚), big ones, and lots of beautiful fish hiding in the sand. I was enjoying the beauty all around me when my instructor waved at me with her hand holding a pink flipper(橡胶蹼). “That flipper looks familiar，” I thought. Yes! That was my flipper! I didn't realize that my right flipper had managed to get away from my right foot! So, that was the first dive. In total, we dove 5 times in 2 days. We managed to dive up to 18 meters in depth. The next dives were smooth and for sure I didn't lose my flipper! I was so happy to see different types of fish swimming in front of me as if I was invisible(不可见的).It was indeed so beautiful and peaceful down there. Now I can see why people love diving under the sea. [语篇解读]　本文是一篇记叙文。作者主要讲述了自己第一次下海潜水的经历。 5．How did the author feel about learning scuba­diving at first? A.Uncertain.　　　　　　 B．Excited. C．Comfortable.

A．Feel tired and sleepy. B．Keep cool and relaxed. C.Keep quiet and patient. D．Feel nervous and worried. D　[词义猜测题。由画线词前面作者问自己的问题“What am I doing？”和“What if something bad happened？”以及下文中的“keep a good thought...Just do it”可知，作者内心紧张、担忧，但努力克服这种感觉，给自己加油打气。] 7．What happened during the author's first dive? A．She saw a sea snake. B．A flipper fell off her foot. C．The sea water turned green. D．She lost her instructor in the sea. B　[细节理解题。由第四段中的“First dive, 12 meters in depth.”以及倒数第二段中的“my right flipper had managed to get away from my right foot”可知，作者第一次在海底潜水时，右脚穿的橡胶蹼脱落了。] 8．What would be the best title for the text? A．A Pleasant Trip to the Beach B．My First Experience with Scuba­diving C．Why a Person Starts Scuba­diving D．How Scuba­diving Affects My Life B　[标题判断题。作者在文章开头两段介绍了学习潜水的原因：想知道为什么许多人喜爱潜水，为海底世界所痴迷。接下来主要讲述了作者参加完潜水课程，进行第一次实地潜水的经历。因此，B项作标题最能概括文章内容。] Ⅱ.七选五 Many facts suggest that children are overweight and the situation is getting worse, according to the doctors. 1 ． Some people blame (责备) the fact that we are surrounded (包围) by shops selling unhealthy, fatty foods, such as fried chicken and ice cream, at low prices. 2 ， then probably children would buy less take­away food. 3 . I agree with this, because good eating habits begin early in life, long before children start to visit fast food shops. If parents often give their children fried chicken and chocolate rather than healthy food, they will go for sweet and salty foods, and children will find it hard to get rid of the habit. There is a third reason for this situation. Children these days take very little exercise. They do not walk to school. When they get home, they sit in front of the television or their computers and play computer games. 4 . What they need is to go outside and play active games or sports. The above are the main reasons for this problem. 5 ， as well as forcing them away from fast food shops and bad eating habits. A．There is another argument that blames parents for allowing their children to become overweight B．Adults are becoming fatter and unhealthier too C．If there were fewer of these restaurants D．Therefore we have to encourage young people to be more active E．Not only is this an unhealthy pastime (消遣), it also gives them time to eat more unhealthy food F．I feel there are a number of reasons for this G．It's a good idea to allow children to eat what they choose [语篇解读]　本文是一篇说明文。文章分析了使孩子超重的因素并建议让孩子们远离快餐店和不良饮食习惯。 1．F　[下文分析了造成上述现象的几个原因，F项引起下文。] 2．C　[本段介绍的是售卖不健康食品的商店和餐馆是孩子发胖的原因。] 3．A　[本段介绍的是孩子发胖的另一个原因，由下文“If parents often give their children fried chicken and chocolate rather than healthy food, they will go for sweet and salty foods, and children will find it hard to get rid of the habit.”可知，如果大人们给他们的孩子吃这些垃圾食品，孩子们很难摆脱这个习惯，故孩子超重应归咎于父母。] 4．E　[本段介绍的是缺少运动是孩子发胖的原因。由上下文语境可知选择E项，进一步说明不运动的危害。] 5．D　[本段是解决问题，对上文进行总结，提出建议。] Ⅲ.完形填空 Western people always give us an impression of being independent. My experience told me that they are good at teamwork, too! During my visit to Valleyview Secondary School, what I heard most often were words like these：“Please do in pairs！”， “Four students a group.” or “Change and form a new group.” In Canada, classes are full of 1 . Students act in groups both inside and outside the classroom. Their stress on team spirit really 2 me. Here is what I saw： Students were 3 to take an exam in this class. They used PowerPoint to make presentations. I was quite interested in such a high­tech 4 of examination. And the students were once again 5 into groups and once again took me by surprise. Each group had three students. One was to control the computer, the second acted as a reporter to ask questions, and the third was the spokesman to give the 6 . Students chose the roles themselves.“I'm 7 in the computer, my friend Darcy is talkative(健谈的) and Alan appears handsome, so we make a great group！” A boy said to me 8 after the exam. How was the students' performance 9 ？“According to the whole group's work, of course.” I got the answer from the teacher. Each student has his strong points and 10 . I thought about the question for a long time after the class: is it fair to 11 every student with the same paper? Canadian schools introduce cooperation into their exams.A student 12 to take the job that he thinks he is good at, and he works with his 13 to try to be the best in class. Isn't it a good way to judge students? We all know that cooperation is 14 ， but how to develop this ability? I do think we can learn something from schools in Canada. Maybe it's a good idea to 15 group activities! [语篇解读]　本文为记叙文。小组活动是加拿大中学教育的一大特色，这有助于培养学生的团队精神。当地老师的小组活动教学让作者感到惊讶。 1．A.arguments　　　　　　　　 B．laughter C．activities D．noise C　[根据上文引号中的内容可知，这些都属于课堂上的小组活动(activity)。] 2．A.moved B．puzzled C．disappointed D．surprised D　[此处是说他们对团队精神的重视让作者感到惊讶。第5空后的once again took me by surprise也是提示。] 3．A.forced B．permitted C．expected D．encouraged C　[此处是说学生们要进行一次考试。be expected to do sth被期待/要求去做某事。] 4．A.task B．way C．plan D．tool B　[此处表示学生使用幻灯片做展示的这种高科技的考试方式(way)。] 5．A.separated B．driven C．invited D．led A　[根据上下文可知，此处指学生们再次被分成小组。be separated into groups被分成小组。] 6．A.explanations B．lectures C．answers D．details C　[此处对应上文中的questions，所以用answers。] 7．A.skilled B．buried C．interested D．engaged A　[根据第12空后的is good at可知，此处指学生一般都选自己擅长的角色。be skilled at/in在……方面熟练。] 8．A.coldly B．slowly C．shyly D．proudly D　[根据语境可知，这名学生向作者介绍了他们的小组，并说自己的小组很优秀，所以用proudly才更能体现这一点。] 9．A.marked B．recorded C．discussed D．shown A　[根据老师的回答和接下来的内容可知，此处作者是问如何给学生打分。mark打分。] 10．A.characters B．advantages C．weaknesses D．performances C　[对应空前的strong points可知此处应是弱点(weakness)。] 11．A.teach B．evaluate C．develop D．test D　[根据语境可知，此处指作者质疑用同一张试卷测试(test)所有学生的公平性。] 12．A.requests B．volunteers C．dreams D．refuses B　[根据语境可知，此处指学生主动承担自己认为所擅长的工作。volunteer作动词，意为“自愿”。] 13．A.friends B．teachers C．roommates D．partners D　[本文的主题是小组活动，所以此处指学生和自己的搭档们(partner)一起努力做到最好。] 14．A.important B．simple C．attractive D．difficult A　[根据常识及下文中作者希望我们学习加拿大的小组活动这种模式可知，作者认为合作很重要(important)。] 15．A.give up B．hope for C．put off D．begin with D　[根据语境及选项可知，此处指从小组活动开始。begin with从……开始。] 单元限时练(二)　B卷 (限时 40分钟) [对应学生用书P187] Ⅰ.语法填空 Most people nowadays are so busy with their lives that they do not have time to enjoy a healthy and 1.

The day we left, my best friend and I cried together in my empty bedroom for hours. I was miserable and homesick during the five­hour car ride to my new house. When we finally arrived at the new house, I ran to the phone to tell my best friend my address and phone number. We talked for a little while, but I had to hang up because the long­distance call was expensive. Both of us agreed to keep in touch with each other forever. On the first day of school, I called her to tell her how everything went. Then, on Halloween，I sent her a letter and a picture of my new friends and me. Finally, she wrote me a letter. It wasn't even a letter—just a bunch of pieces of paper saying，“Best friends forever.” When I finally got her e­mail address, I e­mailed her the longest letter I had ever written. I didn't receive an e­mail, and by the third e­mail with no response, my messages grew shorter and shorter. With each passing day, I got angrier and angrier. I never received a reply from her. Mom said that I could contact my other friends, and that I didn't need to always contact her. Give up my best friend? 注意： 1．所续写短文的词数应为150左右； 2．续写部分为两段，每段的开头已为你写好，不计入总词数。 Paragraph 1： My first answer was automatic, “No way！”　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　 　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　 Paragraph 2： After two years of disappointment，　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　 　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　 [参考范文] Paragraph 1： My first answer was automatic, “No way！” But after five more e­mails, three more phone calls and two more letters, I started to consider what my mom had said. Every night for about a week, I stayed up in bed thinking what I should do. Should I give up or should I keep trying? If I was her best friend, she would spend a minute pushing a few buttons on the phone, or typing a short message on the computer. Paragraph 2： After two years of disappointment, I finally received a phone call from my best friend. She told me how sorry she was for not replying, and how busy she had been. I forgave her. I came to realize that true friends would never really lose their special connection. Even after two years, it felt as if we had just talked yesterday. Now she and I contact each other regularly. 学科网（北京）股份有限公司 $$
