4.A few months after(61)returning(return) to the U.S.from Germany,I(62)took(take) part in a college course in French.Since I had learned to speak German well in Germany,I thought it might be interesting(63)to begin(begin) studying another language.(64)Atthe first class,a teacher asked us to do a pronunciation exercise,in which he would say a word(65)ortwo in French,and each student would do(66)their(they) best to copy.When my turn came,he(67)kept(keep)having me say(68)more(many) words,and I finally asked him why."I find it great(69)fun(funny),"he explained."In 25 years of teaching at school,it's the first time I have heard(70)anAmerican speak French with a German accent."

分析 作者从德国回到美国后决定学习法语,课堂上老师让每个同学跟着老师模仿一两句法语,轮到作者却让他说了更多,作者问道原因,老师回答:我发现很有趣,这是我第一次听到一个美国人带着德国语音说法语.

解答 61.returning;考查非谓语动词,介词after后面要跟动词的动名词形式.  
62.took;考查动词的时态,本文讲述过去发生的事情,故用一般过去式.  
63.to begin;考查动词的不定式,这里是it作形式主语,用不定式短语在句中作真正主语的用法.  
64.At;考查介词,at the first class 是固定搭配,意为"在第一节课上".
65.or;考查固定短语,a word or two意为"一两句话".  
66.their;考查固定短语,do one's best 是固定搭配,意为"尽某人最大的努力".
67.kept;考查动词的时态,本文讲述过去发生的事情,故用一般过去式.  
68.more;考查比较级,结合上下文分析此处与前面的 a word or two作比较,故用比较级形式. 
69.fun;考查名词,形容词great要修饰名词,故用fun,在这里作宾补.  
70.an;考查冠词,不定冠词an表示泛指,an American一名美国人.

点评 短文改错时首先要通读全文,了解文章基本大意,然后细读短文,分析句子结构和句群关系,运用所掌握的词汇,语法,固定搭配等基础知识找出文中错误并加以修改.

3.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 (WHO),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,nearly l8million 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 80per cent over the past three decades.
Maybe that explains why the percentage of people in Finland taking diet pills doubled between 2001and 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 is the"strange"point mentioned in the first sentence?A
A.The good life is a greater risk than the bad life.
B.Starvation is taking more people's lives in the world.
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.A lot of effective diet pills are available.
B.Body image has nothing to do with good food.
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.the cause of heart disease
B.the fashion of body shaping
C.the effectiveness of a campaign
D.the history of a body-conscious country
31.Which would be the best title for the passage?A
A.Actions or Excuses?
B.Overweight or Underweight?
C.WHO in a Dilemma
D.No Longer Dying of Hunger.

15.When a big boat,like a cruise ship,goes through the ocean,it often creates waves.This happens when the large engines on the back of the cruise ship cause the water on the ocean's surface move up and down violently.These waves move out from the boat in both directions.If you are captaining a smaller boat,you'd better steer clear of a ship's wake,so that your boat is not surfing on the waves,causing it to overturn.
A wave is a pattern of motion.When you look at a wave,it may appear as simply water moving across the surface of the ocean.In fact,this is false.The water is actually not moving in the same direction as the wave.While the wave itself-the pattern of motion-is moving across the surface of the ocean,the water is actually moving in a circular motion,which brings the water molecules back to their original position.The water merely gives the appearance of moving forward.
If this is confusing,think of the kind of wave you do at a baseball stadium.Viewed from a distance,the wave is clearly moving across the stadium.But the thing that makes up the wave-the people-are not moving across the stadium,they're just moving up and down in their seats.This is just like the water in an ocean wave.A lot of water is moving up and down,which gives water the appearance of moving along with the wave.
Surfers pay a lot of attention to waves.If you're not in an area where the waves are suitable for surfing,then you can't surf.Usually,surfers gather in areas known for big waves-waves that rise high off the ocean's surface.If the wave is bigger,then the surfer is often able to surf for longer distances and perform more tricks.The height of a wave is known as its amplitude.If you could make a wave freeze,then you could measure the wave's amplitude by running a tape measure from the ocean's surface to the very peak of the wave.
All waves can be measured using amplitude and wavelength.While the waves created by a boat have very small amplitude-sometimes as small as a few centimeters-the wavelength can be very short,as lots of waves are being generated.By contrast,a tsunami has very high amplitude,sometimes more than 100 feet,but a relatively long wavelength,as it's a high wave.
Waves generated in the same way can have great differences in amplitude and wavelength.For example,think back to the cruise ship.While each ship creates waves caused by the movement of the boat,the properties of each of the waves may be very different.For example,a larger cruise ship,with powerful engines,may create a wave that has high amplitude and a short wavelength.However,if the ship's engines slow down,they may then start creating less powerful waves at a slower rate.This would cause the waves'amplitude to decrease,but its wavelength to increase.

61.What does the phrase"steer clear of a cruise ship's wake"in the 1st paragraph mean?D
A.Keeping awake while steering a ship.
B.Getting a clear view of what is ahead.
C.Following the cruise ship very closely.
D.Keeping away from the cruise ship.
62.The author gives an example of wave people do in the stadium in order toC.
A.illustrate how excited people are in a basketball stadium
B.clear the confusion over measuring the wave's amplitude
C.explain why the water appears to move along the waves
D.demonstrate how to make waves in a basketball stadium
63.The last paragraph gives us the impression thatC.
A.the wave's amplitude may vary,but its wavelength remain the same
B.the amplitude of a wave depends on the direction the water moves forward
C.the more powerful the ships'engines are,the higher the waves they generate
D.measuring the amplitude and wavelength of waves is not quite easy
64.What is this passage mainly about?D
A.What makes the sea water move forwards.
B.How to steer a cruise ship in the rough sea.
C.Why people create waves in the stadium.
D.How waves are created and measured.

19.The technique can lead to new ways to produce medicines,the researchers from the universities of Istanbul and Hawaii hope.
As part of an effort to improve treatments for life-threatening illnesses,a team of scientists have created rabbits that glow(发光) in the dark.
Their efforts produced two rabbits out of a litter of eight that went from being a normal,fluffy white to glowing green in the dark.The rabbits were born at the University of Istanbul as part of a collaboration(合作) between scientists from universities in Turkey and Hawaii.
The rabbits glow to show that a genetic manipulation technique can work efficiently,though the specific color is more cosmetic than scientific."The green is not important at all-it's just a marker to show the experiment can be done successfully,"said University of Hawaii associate professor Stefan Moisyadi.
To produce the glowing effect,researchers injected jellyfish DNA into a mother rabbit's embryos.Those altered embryos(胚胎).Those altered embryos were then inserted back into the mother.Similar experiments have resulted in glowing cockroaches and cats.
Eventually,the researchers hope the technique can lead to new ways to produce medicines,Moisyadi said."The final goal is to develop animals that act as barrier reactive to produce beneficial molecules in their milk that
can be cheaply extracted,especially in countries that can't afford big pharma plants that make drugs,that usually cost $1bn to build,and be able to produce their own protein-based medication in animals,"Moisyadi said.
The rabbits are expected to have the same life span as their non-glowing counterparts(副本),but Moisyadi said he understands people can object to this kind of experimentation involving live animals.
"To the people against,I say:think about,what are the benefits and what are the injuries?"Moisyadi said."And if the benefits outweigh the injuries,let's go with the benefits."
Moisyadi,a native of Turkey who is now with the University of Hawaii,started developing the project in 2006,and researchers are now waiting to see if pregnant sheep produce similar results.

21.Moisyadi's attitude towards this kind of experiment isC.
A.doubtful.
B.indifferent.
C.supportive.
D.objective.
22.How did glowing effect produce?D
A.It was just the result of genetic selection.
B.Put a light into a mother rabbit's embryos.
C.Injected glowing cats DNA into a mother rabbit's embryos.
D.Injected Jellyfish DNA into a mother rabbit's embryos.
23.The final goal of this research isD.
A.To make animals cuter.
B.To make nights brighter.
C.To produce all kinds of glowing animals.
D.To produce beneficial molecules in animals'milk.
24.What can we learn according to the passage?C
A.The life span of glowing rabbits is much shorter than that of non-glowing ones.
B.The glowing rabbits were born only at the University pf Hawaii.
C.Scientists have created glowing cockroaches and cats before.
D.Three rabbits out of eight can glow in the experiment.
