12．Why do Americans try hard with watching their weight （體重），while the French，who eat rich food，continue to stay thin？Now a research by Cornell University suggests how life style and decisions about eating may affect weight．Researchers concluded 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 （肥胖率）-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．

9．This text is mainly the relationship betweenB．
A．Americans and the French                     
B．life style and obesity
C．children and adults                                
D．fast food and overweight
10．In what way are the French different from Americans according to Dr．Joseph Mercola？D
A．They go shopping at supermarkets more frequently．
B．They squeeze eating between the other daily activities．
C．They usually eat too much canned and frozen food．
D．They regard eating as a key part of their lifestyles．
11．The text is mainly developedB．
A．by space                                     
B．by comparison
C．by process                                 
D．by classification （分類）
12．Where does this text probably come from？C
A．A TV interview （評論）               
B．A food advertisement （廣告）
C．A health report                              
D．A book review．

20．A 12-year-old girl who had a slight feeling that she might be quite clever has taken a test and proved she was absolutely right．
　　Lydia Sebastian achieved the top score of l62 on Mensa's Cattell III B paper，suggesting she has a higher IQ than well-known geniuses Albert Einstein and Stephen Hawking．
　　The comparison doesn't sit well with the British student，who's currently in Year 8 at Colchester County high school，a selective girl's grammar school in Essex，England．
"I don't think I can be compared to such great intellectuals such as Albert Einstein and Stephen Hawking．They've achieved so much．I don't think it's right．"Lydia told CNN．
　　Lydia sat the test in her summer holidays，after raising the idea with her parents who were in favor of it after some time．
　　It turns out the test wasn't that hard after all．
"I was really nervous before the test and I thought it was going to be really hard．But as I started the test，I thought it was a bit easier than l thought it was going to be，"she said．
　　Lydia's not quite sure what she wants to do when she goes to university，though she's leaning toward something"based around math，because it's one of my favorite subjects．"
"All I'm going to do is work as hard as I can，and see where that gets me，"she said．
　　To put Lydia's mark in perspective，the top adult score in the Cattell III B test，which primarily tests verbal reasoning，is 161．A top 2% score-which allows entry to Mensa，the club for those with high IQs-would be 148 or over．Lydia scored 162，placing her in the top l% of the population．
24．What can we know about Lydia from the passage？B
A．She is a middle school student．
B．She is the cleverest student．
C．She thinks she is cleverer than Einstein．
D．She had thought the test was very easy．

B．be able to attend a famous university
C．have a great interest in math
D．get at least 148 in the IQ test
27．After Lydia graduates from high school，she willA．

1．March 21 has been declared World Sleep Day，a time to recognize and celebrate the value of sleep．Many sleep experts hope it will be a wake-up call．
According to a poll （民意調(diào)查）by the National Sleep Foundation，nearly 4 in 5 Americans don't get as much sleep as they should during the workweek．On average，adults are thought to need at least eight hours of sleep a night，although some can manage with less and some won't do well without more．But the survey found that，on workdays，only 21% of Americans actually get a full eight hours of sleep，and another 21% get less than six．
To many of us，the thought of spending more time sleeping is，well，a big yawn．On the other hand，the thought of being smarter，thinner，healthier and more cheerful can be very attractive．And those are just a few of the advantages that can be ours if we get enough sleep，researchers say．Also on the plus side：We're likely to have better skin，better memories，better judgment，and，oh，yes，longer lives．
"When you lose even one hour of sleep for any reason，it influences your performance the next day，"says Dr．Alon Avidan，director of the UCLA Sleep Disorders Center．
A study published last year found the same to be true even of children．When kids aged 8 to 12 slept for just one hour less for four nights，they didn't function as well during the day．
But sleeping has an image problem．"We see napping or sleeping as lazy，"says Jennifer Vriend，a clinical psychologist in Ottawa，Canada，and the leading author of the study with children．"We put so much attention on diet，nutrition and exercise．Sleep is in the back seat．"In fact，she adds，no matter how much we work out，no matter how well we eat，we can't be in top physical shape unless we also get plenty of sleep．

32．The underlined part in Paragraph 1 meansB．
A．to wake up the sleepers                 B．to draw people's attention
C．to serve as a morning call              D．to declare the special day
33．According to papragrph3，we can conclude thatD．
A．being healthier is one of the advantages for us
B．sleeping has nothing to do with one's expectations
C．spending more time on sleeping is a waste of time
D．enough sleep can be of great benefit to everyone
34．What Jennifer Vriend said in the last paragraph implies thatC．
A．sleeping is an image problem            B．lazy people tend to sleep long  
C．people care little about sleeping       D．sleeping is only part of our life
35．What is the purpose of the passage？A
A．to raise the awareness of enough sleeping．
B．to provide a research result of sleeping．
C．to talk about people's sleeping problems．
D．to stress the function of sleeping at night．

2．You might notice something new in the next few years as you watch Disney programs：Starting in 2015，there won't be any candy，sugary cereal or fast-food commercials（廣告）  aimed at kids．
The Walt Disney Company has become the first major media company to ban ads for junk food on its TV channels，radio stations and websites．It hopes this will stop kids from making poor food choices．First Lady Michelle Obama called it a"game changer"that is sure to send a message to the rest of the children's entertainment industry．"Just a few years ago，if you had told me or any other mom or dad in America that our kids wouldn't see a single ad for junk food while they watched their favorite cartoons on a major TV network，we wouldn't have believed you，"said the First Lady，who heads a campaign to help stop child obesity （肥胖）．
The ban would apply to Disney-owned ABC stations as well as Radio Disney and Disney-owned websites aimed at families with young children．In addition，Disney plans to make changes to its kids'menus at theme parks and resorts（度假勝地）．Fast-food options will be replaced with healthier choices，such as smoothies（果汁），apples，vegetables and yogurt．
In addition to candy bars and fast-food meals，other foods that don't meet Disney's nutritional standards will be banned from the company's kid-targeted media．Any cereal with 10grams or more of sugar per serving will be off the air．There will be no ads for full meals of more than 600calories．Juices with high levels of sugar and foods with too much salt will also be pulled．
Leslie Goodman，Disney's senior vice-president of Corporate Citizenship，said a company that wants to advertise will need to show that it offers a range of healthy options．
Disney isn't the only one pushing away unhealthy foods．Last week，New York City Mayor Michael Bloomberg suggested a ban on drinks over 16ounces sold in movie theaters，restaurants and convenience stores in the Big Apple．He says large，sugary drinks are partly to blame for obesity．
45．What will the Walt Disney Company do from 2015？C
A．Produce more and better cartoons for young kids．
B．Help kids develop healthy lifestyle in the program．
C．Stop broadcasting advertisements for junk food on TV．
D．Provide healthier food for kids while they are watching programs．
46．What Michelle Obama said suggests that while watching cartoons，D．
A．kids didn't believe what the commercials said
B．kids enjoy eating candy，sugary cereal or junk food
C．kids find pleasure in watching fast-food commercials
D．kids were to see a lot of fast-food commercials on TV
47．According to Michael Bloomberg，to fight child obesity，kids shouldB．
A．watch fewer cartoons                   
B．drink less sugary drinks
C．not go to movie theaters               
D．take more physical exercise．
