Electdc Backpack
Backpacks are convenient.They can hold your books，your lunch，and a change of clothes，leaving your hands free to do other things.Someday，if you don，t mind carrying a heavy load，your backpacks might also power your MP3 1 player，keep your cell phone running，and maybe even light your way home.
Lawrence C.Rome and his colleagues from the University of Pennsylvania in Philadelphia2 and the Marine Biological Laboratory in Woods Hole3，Mass.4，have invented a backpack that makes electricity from energy produced while its wcarer walks.In military actions.searchandrescue operations，and scientific field studies，people rely increasingly on cell phones，global positioning system5 receivers，nightvision goggles，and other batterypowered devices to get around and do their work.The backpack，s electricitygenerating feature could dramatically reduce the amount of a wearer，s load now devoted to spare batteries，report Rome and his colleagues in the Sept.9 Science6.
The backpack，s electricitycreating powers depend on springs used to hang a cloth pack from its metal frame.The
frame sits against the wearer，s back，and the whole pack moves up and down as the person walks.A gear meehanism converts vertical movements of the pack to rotary motions of an electrieal generator，producing up to 7.4 watts.

Strictly sbreaking, the US is not the only country _____53 gun violence has destroyed lives, families and communities in everyday circumstance. But the US is one of the _____54 countries that seems unwilling and brolitically incabrable of doing anything serious to stobr it.
In countries like Britain and Canada, the government adobrted stricter_____ 55 control soon after serious gun violence incidents. US leaders, however, are held _____56 by the gun lobby and the electoral system.

Germs on Banknotes
People in different countries use different types of 1 yuan in China, pesos in Mexico, pounds in the United Kingdom, dollars in the United States, Australia and New Zealand. They may use 2 currencies, but these countries, and probably all countries, still have one thing in common1: Germs on the banknotes.
Scientists have been studying the germs on money for well over2 100 years. At the turn of the 20th 3 , some researchers began to suspect that germs living on money could spread disease.
Most studies of germy money have looked at the germs on the currency 4 one country. In a new study, Frank Vriesekoop3 and other researchers compared the germ populations found on bills of different 5 .
Vriesekoop3 is a microbiologist at the University of Ballarat in Australia4. He led the study, which compared the germ populations found on money 6 from 10 nations. The scientists studied 1,280 banknotes in total; all came from places where people buy food, like supermarkets street vendors and cafes, 7 those businesses often rely on cash.
Overall, the Australian dollars hosted the fewest live bacteria ---- no more than 10 per square centimeter. Chinese yuan had the most ---- about 100 per square centimeter. Most of the germs on money probably would not cause harm.
What we call “paper” money usually isn't made from paper. The U. S. dollar, for example, is printed on fabric that is mostly 8 .Different countries may use different 9 to print their money. Some of the currencies studied by Vriesekoop and his 10 such as the American dollar were made from cotton. Others were made from polymers.
The three 11 with the lowest numbers of bacteria were all printed on polymers. They included the Australian dollar, the New Zealand dollar and some Mexican pesos.
The other currencies were printed on fabric made 12 of cotton. Fewer germs lived on the polymer notes. This connection suggests that 13 have a harder time staying alive on polymer surfaces. Scientists need to do more studies to understand how germs live on money-----and whether or not we need to be concerned. Vnesekoop is now starting a study that will 14 the amounts of time bacteria can stay alive on different types of bills.
Whatever Vriesekoop finds, the fact remains: Paper money harbors germs We should wash our 15 after touching it; after all5, you never know where your money 's been. Or what's living on it

A famous teacher was speaking to the students at our school. He began his lesson by holding up a 100 bill. Then he said to the three hundred students, “Who would like this 100 bill?” The students began to put up their hands at once.
Then he said, “I am going to give this 100 to one of you, but first, let me do this.” He then made the bill into a ball. Then he said, “Who wants it now?” The hands went back into the air.
“Well,” he said, “What if I do this?” and he dropped it on the floor and stepped on it. He picked up the dirty, crumpled bill and said, “Who still wants it?” Hands went back into the air.
“My friends,” he said, “you have learned a valuable lesson today. No matter (无论) what I did to the money, you still wanted it because it did not go down in value (价值). It was still worth l00!”
Many times in our lives, we are dropped, crumpled, and stepped on by the chances we take and the things that happen to us. We feel as if we are worth nothing. But remember, no matter what has happened to you, you will never lose your value: you are always valuable to those people who love you. Your value doesn’t come from what you do or whom you know, but WHO YOU ARE.
You are special and valuable. Don’t ever forget it!

B. the students put down their hands
C. the students put their hands behind their backs again
D. the students put their hands in front of them
5. Why did the famous teacher use a 100 bill at his lesson?
A. Because he wanted to make the bill into a ball.
B. Because he used to drop a bill on the floor and stepped on it.
C. Because he was going to give the bill to one of his students.
D. Because he wanted to make the students know what value was.
【答案及解析】
1. 选C。根据第4段中的No matter what I did to the money, you still wanted it because it did not go down in value可知答案。
2. 选D。根据第5段中的you are always valuable to those people who love you可知答案。
3. 选D。根据第5段中的Your value doesn’t come from what you do or whom you know, but WHO YOU ARE可知答案。
4. 选A。老师第一次问Who would like this 100 bill? 时，同学们的反应是：The students began to put up their hands at once. 老师第二次问Who wants it now? 时， 同学们的反应是：The hands went back into the air. 老师第三次问：Who still wants it? 时，同学们的反应是：Hands went back into the air. 很显然，Hands went back into the air 中的back有类似again的含义，故选A。
5. 选D。通读全文可以看出，老师利用这张百元大钞作“教具”，其目的是想告诉同学们，无论你怎样折腾这张百元大钞，它的价值都不会因此而减少。所以答案选D最佳。

American Dreams
There is a common response to America among foreign writers： the US is a land of extremes where the best of things are just as easily found as the worst. This is a cliché（陈词滥调）。
In the land of black and white，people should not be too surprised to find some of the biggest gaps between the rich and the poor in the world. But the American Dream offers a way out to everyone.______________（1） No class system or government stands in the way.
Sadly，this old argument is no longer true. Over the past few decades there has been a fundamental shift in the structure of the American economy.
The gap between the rich and the poor has widened and widened. ______________（2）
Over the past 25 years the median US family income has gone up 18 per cent. For the top 1 per cent，however，it has gone up 200 per cent. Twenty-five years ago the top fifth of Americans had an average income 6.7 times that of the bottom fifth. ______________（3）
Inequalities have grown worse in different regions. In California，incomes for lower class families have fallen by 4 per cent since 1969. ______________（4） This has led to an economy hugely in favor of a small group of very rich Americans. The wealthiest 1 per cent of households now control a third of the national wealth. There are now 37 million Americans living in poverty. At 12.7 per cent of the population，it is the highest percentage in the developed world.
Yet the tax burden on America's rich is falling，not growing. ______________（5） There was an economic theory holding that the rich spending more would benefit everyone as a whole. But clearly that theory has not worked in reality.
A Nobody is poor in the US.
B The top 0.01 per cent of households has seen its tax bite fall by a full 25 percentage points since 1980.
C For upper class families they have risen 41 per cent.
D Now it is 9.8 times.
E As it does so，the possibility to cross that gap gets smaller and smaller.
F All one has to do is to work hard and climb the ladder towards the top.

第2部分：阅读判断(第16～22题，每题1分，共7分)
下面的短文后列出了7个句子，请根据短文的内容对每个句子做出判断：如果该句提供的是正确信息，请选择A;如果该句提供的是错误信息，请选择B;如果该句的信息文中没有提及，请选择C。
Earth Rocks On
Most of the time, the ground feels solid beneath our feet. That's comforting. But it's also misleading because there's actually a lot going on underground. Masses of land (called plates) slip, slide, and bump against each other, slowly changing the shape of continents and oceans over millions and billions of years.
Scientists know that Earth formed about 4.5 billion years ago. They also know that our planet was hot at first. As it cooled, its outermost layer, called the crust, eventually formed moving plates. Exactly when this shift happened, however, is an open question.
Now, an international group of researchers has an answer. They've found new evidence suggesting that Earth's crust (地壳) started shifting at least 3.8 billion years ago. The new estimate is 1.3 billion years earlier than previous ones.
Not long before 3.8 billion years ago, lots of asteroids (小行星) were pummeling Earth, keeping its crust in a hot, molten state. After the hard crust formed, much of it sank at various times into the planet's hot insides. There, it melted before returning to the surface as lava.
In some places, however, the crust never sank. One of the oldest such places is in Greenland, in an area called the Isua supracrustal(上地壳) belt. The rocky crust there is between 3.7 and 3.8 billion years old. The belt was once part of the seafloor, but now it is exposed to air.
The researchers recently look at the Isua supracrustal belt. They noticed long, parallel cracks in the rock that have been filled in with a type of volcanic rock.
To explain this structure, the scientists propose that tension in the crust caused the seafloor to crack open long ago. Hot, liquid rock, called magma(岩浆), flowed up slowly from deep inside Earth to fill the cracks. Finally, the area cooled, forming what we see today.
That explanation, plus chemical clues inside the rock, suggests that the Isua supracrustal belt was once part of a plate under the ocean, beginning around 3.8 billion years ago.

The IPad
1 The IPad is a tablet computer (平板电脑) designed and developed by Apple. It is particularly marketed as a platform for audio and visual media such as books, periodicals (期刊), movies, music, and games, as well as web content. At about 1.5 pounds (680 grams), its size and weight are between those of most contemporary smartphones and laptop computers. Apple released the IPad in April 2010, and sold 3 million of the devices in 80 days.
2 The IPad runs the same operating system as IPod Touch and IPhone. It can run its own applications as well as ones developed for IPhone. Without modification, it will only run programs approved by Apple and distributed via its online store.
3 Like IPhone and iPod Touch, the IPad is controlled by a multitouch display-a break from most previous tablet computers, which uses a pressure-triggered stylus (触控笔). The IPad uses a Wi-Fi data connection to browse (浏览) the Internet, load and stream media, and install software. Some models also have a 3G wireless data connection which can connect to GSM 3G data networks. The devices is managed and synchronized (同步) by ITunes on a personal computer via USB cable.
4 An IPad has different features and applications one can use to execute different and interesting things. There are lots of IPad applications that the owner can use to enhance the way they communicate. Some of these are how to use social networking sites and other online options. One of the most common uses is for e-mail services. IPand applications like Markdown Mail allow the adoption of specific and particular options. They enable the owner to personalize their email accounts.
5 While the IPad is mostly used by consumers it also has been taken up by business users. Some companies are adopting IPads in their business offices by distributing or making available IPads to employees. Examples of uses in the workplace include lawyers responding to clients, medical professionals accessing health records during patient exams, and managers approving employee requests. A survey by Frost & Sullivan shows that IPad usage in workplaces is linked to the goals of increased employees productivity, reduced paperwork, and increased revenue.

第一篇 Cell Phones: Hang Up or Keep Talking?
Millions of people are using cell phones today. In many places it is actually considered unusual not to use one. In many countries, cell phones are very popular with young people. They find that the phones are more than a means of communication―having a mobile phone shows that they are cool and connected.
The explosions around the world in mobile phone use make some health professional worried. Some doctors are concerned that in the future many people may suffer health problems from the use of mobile phones. In England, there has been a serious debate about this issue. Mobile phone companies are worried about the negative publicity of such ideas. They say that there is no proof that mobile phones are bad for your health.
On the other hand, why do some medical studies show changes in the brain cells of some people who use mobile phones? Signs of change in the issues of the brain and head can be detected with modern scanning (扫描) equipment. In one case, a traveling salesman had to retire at a young age because of serious memory loss. He couldn't remember even simple tasks. He would often forget the name of his own son. This man used to talk on his mobile phone for about six hours a day, every day of his working week, for a couple of years. His family doctor blamed his mobile phone use, but his employer's doctor didn't agree.
What is it that makes mobile phones potentially harmful? The answer is radiation. High-tech machines can detect very small amounts of radiation from mobile phones. Mobile phone companies agree that there is some radiation, but they say the amount is too small to worry about.
As the discussion about their safety continues, it appears that it's best to use mobile phones less often. Use your regular phone if you want to talk for a long time. Use your mobile phone only when you really need it. Mobile phones can be very useful and convenient, especially in emergencies. In the future, mobile phones may have a warning label that says they are bad for your health. So for now, it's wise not to use your mobile phone too often

34 D 请见第四段里的这句话: Mobile phone companies agree that there is some radiation，but they say the amount is too small to worry about.它们并不否认手机有辐射，但声称辐射量 很小无需担心。
35 C 作者建议大家少用手机，这一点在最后一段里可以清楚地看到。
第二篇 Some People Do Not Taste Salt Like Others
Low-salt foods may be harder for some people to like than others, according to a study by a Penn State College of Agricultural Sciences food scientist. The research indicates that genetic factors influence some of the difference in the levels of salt we like to eat.
Those conclusions are important because recent, well-publicized (大力宣传的) efforts to reduce the salt content in food have left many people struggling to accept fare that simply does not taste as good to them as it does to others, pointed out John Hayes, lead investigator on the study.
Diets high in salt can increase the risk of high blood pressure and stroke. That is why public health experts and food companies are working together on ways to help consumers lower salt intake through foods that are enjoyable to eat. This study increases understanding of salt preference and consumption.
The research involved 87 carefully screened participants who sampled salty foods such as soup and chips, on multiple occasions, spread out over weeks. Test subjects were 45 men and 42 women, reportedly healthy, ranging in age from 20 to 40 years. The sample was composed of individuals who were not actively modifying their dietary intake and did not smoke cigarettes. They rated the intensity of taste on a commonly used scientific scale, ranging from barely detectable to strongest sensation of any kind.
“Most of us like the taste of salt. However, some individuals eat more salt, both because they like the taste of saltiness more, and because it is needed to block other unpleasant tastes in food,” said Hayes. “Supertasters, people who experience tastes more tensely, consume more salt than nontasters do. Snack foods have saltiness as their primary flavor, and at least for these foods, more is better, so the supertasters seem to like them more. ”
However, supertasters also need higher levels of salt to block unpleasant bitter tastes in foods such as cheese, Hayes noted. “For example, cheese is a wonderful blend of dairy flavors from fermented (发酵的), milk, but also bitter tastes from ripening that are blocked by salt,” he said. “A supertaster finds low-salt cheese unpleasant because the bitterness is too pronounced.
Hayes cited research done more than 75 years ago by a chemist named Fox and a geneticist named Blakeslee, showing that individuals differ in their ability to taste certain chemicals. As a result, Hayes explained, we know that a wide range in taste acuity exists, and this variation is as normal as variations in eye and hair color.
36 John Hayes pointed out that __________.
A food with less salt tastes better.
B many people never eat low-salt food.
C many people make efforts to accept low-salt food.
D it is good to health to eat food without salt.
37 The fourth paragraph briefly describes______?
A why the number of subjects was limited to 87.
B why more male subjects were chosen than female ones.
C how salty foods were made and distributed to the subjects in the research.
D how the subjects were selected and what they were asked to do.
38 It is true that ________.
A nontasters like to share salty cheese with supertasters.
B supertasters like the taste of saltiness to block sweet tastes in food.
C nontasters consume more salt because they like intense tastes.
D supertasters like snack foods more as they contain higher levels of saltiness.
39 Supertasters prefer high-salt cheese because ________.
A it is good to health.
B it tastes less bitter.
C it is rich in nutrition.
D it has intense bitter tastes.
40 It can be inferred from the last paragraph that taste acuity is ________.
A genetically determined.
B identified with certain chemicals.
C developed over time after birth.
D related to one's eye and hair color.
36 C 文章第 2 段提到 John Hayes 指出”尽管对于许多人来说，并不像别人那样喜欢吃低盐食品，但近来大力的宣传使得很多人努力接受了低盐饮食“。选择 C 符合题意。
37 D 第四段主要讲述了这项研究如何选取了研究对象，包括研究对象的人数、性别、健 康状况、口味轻重分级等。由此可知第四段主要描述的是如何选择研究对象以及要求他们做什么。答案为 D。
38 B 文章第五段最后一句话”盐是零食的第一调味品，至少对于这些食物，盐越多越好， 所以口味重的人看起来更喜欢他们“。选项 B 正是这个意思。其他选项的意思与文章原意不符。
39 B 文章第六段最后一句话提到”口味重的人觉得低盐的奶酪吃起来不舒服是因为这种 奶酪苦味太浓“。选项 B 符合文章的意思。
