17.Everyone knows that if a dog's ears are up and its tail is wagging vigorously,it is definitely pleased to see you.but now scientists using a robot have found that the way dogs use their tails is more complicated than we thought,and that dogs which wag them to the left may be more friendly.The animal psychologists discovered that when real dogs approached a life-sized robot dog,they were less cautious about it when it was wagging its tail to the left,while if it was wagging its tail to the right,far fewer dogs approached it in a confident manner.
In the first experiments,56percent of the animals approached the model without hesitation when the tail was wagged to the left,while only 21percent did so in the other situation.When the researchers excluded(排除)owners from being present,the result were:31percent of the dogs approached continuously when the tail was wagging to the left,while only 18percent did so when it was on the right.
Animal psychologist Roger Mugford said it added to the growing evidence that dogs were even more complicated communicators than the animals more closely related to man such as monkeys.He said,"We know that dogs,in a sense,have languages,but it is more complicated because it is not just them wagging their tails,but also giving out chemical displays."
He adds,"The research confirms earlier studies suggesting that dogs,like humans,had a left-side preference.If you are going to present a signal to a dog,it is sensible to put it on your left-hand side because that is where dogs,unlike most other animals,tend to look.It is another example of the similarity between dogs and humans.They are a lot more human than we give them credit for."

32.What does it tell us if a dog wags its tail to the right?C
A.It was very energetic.
B.It was in a good mood.
C.It might be unfriendly.
D.It must be confident.
33.What can be inferred from the second paragraph?D
A.Few dogs approached the robot dog confidently.
B.More dogs approached the robot without their owners present.
C.Some dogs lacked confidence with their owners present.
D.Dog owners may influence the behaviour of their dogs.
34.What can we learn from animal psychologist's experiments?C
A.Dogs can communicate more than human beings.
B.Dogs have more complicated emotions than monkeys.
C.Dogs'tail-wagging conveys more information than previously believed.
D.Dogs'intelligence can be much higher than any other kind of animal.
35.What do Roger Mugford's words mean?B
A.The Left-side preference should be studied further.
B.Dogs have more in common with humans than we think.
C.No other animals show the left-side preference except dogs.
D.Dogs have a more complicated language than we people do.

分析 科学实验表明:狗摇尾巴传达了更多的我们以前不知道的信息,并且狗和人类还有许多我们以前不知道的相似性.

解答 32.C.细节理解题.根据第一段dogs which wag them to the left may he more friendly.while if it was wagging its tail to the right,far fewer dogs approached it in a confident manner.和第二段的实验结果可知如果狗往右侧摇尾巴,说明它不友好,很少有其他狗接近它.故选C.
33.D.细节理解题.根据第二段实验中提到的When the researchers excluded(排除)owners from being present可知主人是否在场会影响狗的行为,故选D
34.C.细节理解题.根据文章He said,"We know that dogs,in a sense,have languages,but it is more complicated because it is not just them wagging their tails,but also giving out chemical displays可知我们可以从动物心理学家的实验中学到狗摇尾巴传达比以前认为的更多信息;故选C
35.B.推理判断题.根据最后一段The research confirms earlier studies suggesting that dogs,like humans,had a left-side preference.和It is another example of the similarity between dogs and humans.They are a lot more human than we give them credit for.可知狗和人类有许多我们以前不知道的相似性,故选B.

点评 考察学生的细节理解和推理判断能力,做细节理解题时一定要找到文章中的原句,和题干进行比较,再做出正确的选择.在做推理判断题不要以个人的主观想象代替文章的事实,要根据文章事实进行合乎逻辑的推理判断.

12.It is reported that bags are getting bigger all the time,and that there are more bags per person on the street today than at any other time in history.If this is true,possible explanations could include the wide use of small electric and electronic devices,a reading-material explosion,a popular interest toward tight or pocket less clothing,or cheap bagmaking labor overseas.
But,much as nature finds ways-such as disease-to control overpopulation,city life has thrown up impediments(障碍)to bags.To enter many public buildings,such as theatres and railway stations,you must go through a search or go bagless.The city has countless bag rules.It is hard to keep them all straight,and you're never sure,when leaving home for the day,whether it might be a bad idea to bring one along.
Last week,the New York Public Library got in the game.Students,researchers,writers,historians,and anyone else who has got used over the years to treating the vast Rose Main Reading Room as an office or a reading room came up against a new rule.You are no longer allowed to bring a bag larger than eleven inches by fourteen inches into the library.If you walk in with one,you must leave it at the coat check.You may keep its contents with you,however,and the library provides big clear plastic bags for them.You return them when you come back for your own bag.
What the library is trying to prevent,in this case,is people taking things out,rather than bringing things in.A librarian said on the second day,"It's a big change for people who used to come and bring in half their flats.The people who use the library responsibly will continue to do so.The people who steal will continue to get away with it,if they really want to."

24.How many reasons does the author list to explain the changes related to bags?C
A.2    B.3    C.4    D.5
25.What do the bag rules in many public buildings require people to do?A
A.Have their bags examined.    B.Pay for bringing in bags.
C.Leave the places bagless.    D.Use big clear plastic bags.
26.What is the purpose of the new rule at the New York Public Library?B
A.To change people's way of reading.
B.To prevent people stealing things.
C.To help people better use the library.
D.To stop people from bringing in dangerous things.
27.How is the effect of the new rule according to the librarian?D
A.Excellent.    B.Satisfacfory.    C.Harmful.    D.Limited.

8.We've reached a strange-some would say unusual-point.While fighting world hunger continues to be the matter of vital importance according to a recent report from the World Health Organization,more people now die from being overweight,or say,from being extremely fat,than from being underweight.It's the good life that's more likely to kill us these days.
Worse still,nearly 18 million children under the age of five around the world are estimated to be overweight.What's going on?
We really don't have many excuses for our weight problems.The dangers of the problem have been drilled into us by public-health campaigns since 2001 and the message is getting through-up to a point.
In the 1970s,Finland,for example,had the highest rate of heart disease in the world and being overweight was its main cause.Not any more.A public-health campaign has greatly reduced the number of heart disease deaths by 80 percent over the past three decades.
Maybe that explains why the percentage of people in Finland taking diet pills doubled between 2001 and 2005,and doctors even offer surgery of removing fat inside and change the shape of the body.That has become a sort of fashion.No wonder it ranks as the world's most body-conscious country.
We know what we should be doing to lose weight-but actually doing it is another matter.By far the most popular excuse is not taking enough exercise.More than half of us admit we lack willpower.Others blame good food.They say:it's just too inviting and it makes them overeat.Still others lay the blame on the Americans,complaining that pounds have piled on thanks to eating too much American-style fast food.
Some also blame their parents-their genes.But unfortunately,the parents are wronged because they're normal in shape,or rather slim.
It's a similar story around the world,although people are relatively unlikely to have tried to lose weight.Parents are eager to see their kids shape up.Do as I say-not as I do.

28.What's the"strange"point mentioned in the first sentence?B
A.Starvation is taking more people's lives in the world.
B.The good life is a greater risk than the bad life.
C.WHO report shows people's unawareness of food safety.
D.Overweight issue remains unresolved despite WHO's efforts.
29.Why does the author think that people have no excuse for being overweight?C
A.Body image has nothing to do with good food.
B.A lot of effective diet pills are available.
C.They have been made fully aware of its dangers.
D.There are too many overweight people in the world.
30.The example of Finland is used to illustrateC.
A.there are too many overweight people in the world
B.the cause of heart disease        
C.the effectiveness of a campaign
D.the fashion of body shaping
31.Which would be the best title for the passage?B
A.Overweight or Underweight
B.Actions or Excuses   
C.WHO in a Dilemma
D.No Longer Dying of Hunger.
