Test 5
Ⅰ.阅读理解
A
Math is no problem for Chad Qian,14.He is the champion of the 2012 Raytheon MATHCOUNTS National Competition (RMNC)．The event was held in front of a live audience at Disney World，in Orlando，Florida，on May 11.Qian competed against more than 220 middle school students for the title.He won the grand prize：an 8,000 Donald G．Weinert Scholarship and a trip to U．S.Space Camp in Huntsville，Alabama.“I felt sort of shocked and I was very surprised，”Qian said.“I was very excited that I had won.”
MATHCOUNTS is an educational program which offers free materials to parents and teachers to help kids sharpen their math skills.More than 6,000 schools competed to earn a qualification at RMNC this year.Students had to win local competitions and then place in the top four of their peers(同龄人) during their state competition.Students traveled from all 50 states to compete at the event.Erikson，a spokesperson for Raytheon，says，“It teaches students more than just math.I think it teaches people how to compete and how to stay focused on the task at hand to achieve the results you want，”she said.
Qian says when he grows up he will most likely follow a career in math and science or medicine.His advice to other students looking to take part in a math competition is to keep practicing.“Get other people who like math also and work together so you can learn from each other，”he said.“Just practice and learn as much as you can.” 1．What did Qian think of the result of the competition? A．He thought little of it. B．He took great pride in it. C．It came out as expected. D．It was beyond his expectation. 答案 D
解析 细节理解题。根据第一段中Qian所说的话“I felt sort of shocked and I was very surprised”可知选D项。
2．What does a competitor have to do to take part in RMNC?
A．Become a winner in local competitions. B．Beat each competitor in the competitions. C．Use the materials given by MATHCOUNTS. D．Travel around all 50 states to compete. 答案 A
解析 细节理解题。根据第二段第三句“Students had to win local competitions and then place in the top four of their peers(同龄人) during their state competition.”可知选A项。 3．What do we know of the competition from Erikson’s words? A．It benefits students greatly. B．It will become the focus of students. C．It urges students to learn other subjects. D．It can help students achieve their life goals. 答案 A
解析 推理判断题。根据第二段中Erikson所说的话可知，全美数学大赛不仅教学生学习数学，而且教人们如何比赛，如何为了达到想要的效果而专注于手头上的任务。因此，这个比赛会使学生受益匪浅。
4．What’s the best title of the text? A．How a Math Contest Works B．Ways to Win in a Competition C．Chad Qian Won the 2012 RMNC D．The Secret of Qian’s Great Success 答案 C
解析 标题归纳题。本文主要介绍了Chad Qian获得了2012年全美数学大赛的冠军，因此C项为最佳标题。

Why do Americans struggle with watching their weight，while the French，who consume rich food，continue to stay thin？Now a research by Cornell University suggests how life style and decisions about eating may affect weight.Researchers conclude that the French tend to stop eating when they feel full.However，Americans tend to stop when their plate is empty or their favorite TV show is over.
According to Dr.Joseph Mercola，a health expert，the French see eating as an important part of their life style.They enjoy food and therefore spend a fairly long time at the table，while Americans see eating as something to be squeezed between the other daily activities.Mercola believes Americans lose the ability to sense when they are actually full.So they keep eating long after the French would have stopped.In addition，he points out that Americans drive to huge
supermarkets to buy canned and frozen foods for the week.The French，instead，tend to shop daily，walking to small shops and farmers’ markets where they have a choice of fresh fruits，vegetables，and eggs as well as high-quality meats for each meal.
After a visit to the United States，Mireille Guiliano，author of French Women Don’t Get Fat，decided to write about the importance of knowing when to stop rather than suggesting how to avoid food.Today she continues to stay slim and rarely goes to the gym.
In spite of all these differences，evidence shows that recent life style changes may be affecting French eating habits.Today the rate of obesity—or extreme overweight—among adults is only 6%.However，as American fast food gains acceptance and the young reject older traditions，the obesity rate among French children has reached 17%—and is growing.(2014·陕西，C) 5．In what way are the French different from Americans according to Dr.Joseph Mercola? A．They go shopping at supermarkets more frequently. B．They squeeze eating between the other daily activities. C．They regard eating as a key part of their life style. D．They usually eat too much canned and frozen food. 答案 C
解析 细节理解题。根据短文第二段第一句中的“the French see eating as an important part of their life style”可知答案为C项，其中see...as与regard...as同义，意为“将……视作/看作”。而A、B、D三项都是美国人的生活习惯，所以排除。 6．This text is mainly about the relationship between . A．Americans and the French B．life style and obesity C．children and adults D．fast food and overweight 答案 B
解析 主旨大意题。通读全文可知，本文主要讲的是人的生活方式是如何影响其体重的，所以B项为正确答案。
7．This text is mainly developed . A．by contrast B．by space C．by process D．by classification 答案 A
解析 写作手法题。本文主要通过比较法国人和美国人的生活方式而得出有关生活方式与体重之间关系的结论，所以选择A项by contrast(通过对比)。 8．Where does this text probably come from?
