Kelly Reeves was getting ready for a trip when her phone slipped into a sink full of water. Panic moment! She quickly picked up the wet phone and tried to turn it on, but nothing worked. Her first reaction? She got dressed, drove to the nearest store, and bought a new mobile at full price.
A new study finds that fear of losing your phone is a common illness. About 66 percent of those surveyed suffer from nomophobia or “no mobile phone phobia”. Interestingly, more women worry about losing their phone than men.
Fortunately, there’s a solution.
The first step is to figure out if you have nomophobia. Checking your phone too often is one thing, but the true sign of a problem is that you can’t conduct business or go about your routine when the fear becomes so severe.
Do you go to unusual lengths to make sure you have your phone? That’s another sign of a problem. If you find you check your phone plenty of times per hour, or a total of an hour per day, there may be a problem.
Some of the treatments are similar to those for treating anxiety attacks: leaving the phone behind and not checking e-mail or text messages, and then learning to tolerate the after anxiety. Even if this leads to a high level of worry and stress, the solution is to push through the fear and learn to deal with not having your phone.
Of course, there are also technological alternatives. Luis Levy, a co-founder at Novy PR, says he uses an application called Cerberus that can automatically track the location of his phone. To find it, he can just go to a website and see the phone’s location.
He also insures his phone through a service called Asurion. The company’s description of its product reads like a prescription for anxiety:”60 million phones are lost, stolen or damaged each year. You’ll have complete peace of mind knowing that your phone is protected and you can quickly reconnect with family, friends and work, as soon as the very next day!”

Hundreds of years ago, life was much harder than it is today. People didn’t have modern machines. There was no modern medicine, either.
Life today has brought new problems. One of the biggest is pollution. Water pollution has made our rivers and lakes dirty. It kills our fish and pollutes our drinking water. Noise pollution makes us talk louder and become angry easily. Air pollution is the most serious kind of pollution. It is bad for all living things in the world.
Many countries are making rules to fight pollution. We need to do many other things. We should put waste things in the dustbins instead of on the ground. We can go to work by bus or with our friends in the same car. If there are fewer people driving, less pollution will be made. Rules are not enough to solve the problems. Every person must help to fight pollution.
【小题1】Hundreds of years ago, life was much harder than it is today because _____.

C. we have to drink dirty water    
D. people are making rules to control pollution

The world is not hungry, but it is thirsty. It seems strange that nearly 3/4 of the earth is covered with water while we say we are short of water. Why? Because about 97% of water on the earth is sea water which we can’t drink or use for watering plants directly. Man can only drink and use the 3% the water that comes from rivers and lakes. And we can’t even use all of that, because some of it has been polluted.
Now more water is needed. The problem is: can we avoid a serious water shortage later on? First, we should all learn how to save water. Secondly, we should find out the ways to reuse it. Scientists have always been making study in this field. Today, in most large cities water is used only once and then runs to the sea or rivers. But it can be used again. Even if every large city reused its water, still there would not be enough. What could people turn to next?
The sea seems to have the best answer. There is a lot of water in the sea. All that needs to be done is to get the salt out of the sea water. This is expensive, but it’s already in use in many parts of the world. Scientists are trying to find a cheaper way of doing it. So you see, if we can find a way out, we’ll be in no danger of drying up.
【小题1】The world is thirsty because ___________.

A．3/4 of the earth is covered with water

B．we have enough sea water

C．we haven’t used all the water in rivers and lakes

D．water can be used only once

There are many colors in nature. But do you know if a color has weight? I think you’ll say “no”. But I am afraid you are wrong. If you don’t believe, you may do a small experiment.
First, put two objects（物体） with the same weight into two boxes. Then cover the box. Third, wrap(裹) one box with a red piece of paper, the other with a white piece of paper. OK. Now hold the boxes with your hand one by one. It is certain that you will think the red one is a little heavier.
Why do you think so? A scientist found that different colors have different weights in a man’s mind. So he did many tests and at last he got the result. That is to say, every color has its own weight in our mind and their order is the same. The heaviest color is red, then blue, green, yellow and white.
The scientist told us that colors also have smell. Can you smell the color? Of course not. Then why did the scientist say so? That is because every color stands for (代表)a kind of light with a certain wavelength(波长). It reaches our brain through sense organs(感觉器官).
According to this discovery, scientists say that people accept the colors they like, and refuse the colors they hate. So your body and mind will be healthy by using the colors you like. Or you’ll be nervous or ill. For example, if you stay in a room with red windows, wallpapers and furniture for two hours, you’ll feel you have been there for four hours. But if the room is blue, you’ll feel you have been there for only an hour. Another example, if a person walks out of a red room and into a blue room, his temperature will fall. That means our body temperature will change with different colors.
【小题1】The idea of the second paragraph is to tell us ________.

A．a red box is heavier than a white one

B．a color has weight in one’s mind

C．white paper is lighter than red paper

D．you can know the weight of a color by holding it

【小题2】Why did the scientist say colors have smell?

A．Because people can sense(感觉) the light from colors.

B．Because we can smell colors with our noses.

C．Because every color has its own sweet smell.

D．Because every color can give off light of the same length.

【小题3】If a person walks from a blue room to a red room, his body temperature will__________.

A．rise

B．fall

C．stay the same

D．change now and then

【小题4】It can be known from the text that________.

A．colors have order in weight

B．colors can change the weight of an object

C．people would stay longer in a room with red windows

D．colors can affect （影响）our mood （情绪）and health

【小题5】This passage is probably a __________.

Human wants seem endless, When a starving man gets a meal, he begins to think about an overcoat; when a manager gets a new sports car, he dreams of country clubs and pleasure boats dance into view.
The many wants of mankind might be regarded as making up several levels. When there is money enough to satisfy one level of wants, another level appears.
The first and most basic level of wants is food. Once this want is satisfied, a second level of wants appears: clothing and some sort of shelter. By the end of World War II these wants were satisfied for a great majority of Americans. Then a third level appeared. It included such items as cars and new houses.
By 1957 or 1958 this third level of wants was fairly well satisfied. Then in the late 1950s a fourth level of wants appeared: the “life-enriching” level. While the other levels mean physical satisfaction—the feeding, comfort, safety and transportation of the human body—this level means mental needs for recognition, achievement and happiness, It includes a variety of goods and  services many of which could be called “luxury” items. Among them are vacation trips, the best medical care and entertainment. Also included here are fancy foods and the latest styles in clothing.
On the fourth level, a greater percentage of consumers spending goes to services, while on the first three levels more is spent on goods. Will consumers raise their sights to a fifth level of wants as their income increases, or will they continue to demand luxuries and personal services on the fourth level?
A fifth level probably would be wants that can be achieved by community action. Consumers may be spending more on taxes and crime. After filling our stomachs, our garages, and our minds, we now may seek to ensure the health and safety to enjoy more fully the good things on the first three levels.
【小题1】According to the passage, man will begin to think about such needs as housing and clothing only when _______

A．he has saved up enough money

B．he has grown dissatisfied with his simple shelter

C．he has satisfied his hunger

D．he has learned to build houses

【小题2】It can be inferred from the passage that by the end of World War II most Americans ______

A．were very rich

B．were very poor

C．Had the good things on the first three levels

D．didn’t own cars

【小题3】Which of the following is NOT related to “physical satisfaction”?

A．A successful career	B．A comfortable house
C．A good service	D．A family car

【小题4】Which is the main want of man on the fourth level?

A．The more goods, the better

B．The more mental satisfaction, the better

C．The more “luxury” items, the better

D．The more earning, the better

【小题5】The author thinks that a fifth level______

A．would be a little better than the fourth level

B．may be a lot more desirable than the first four

C．can be the last and most satisfying level

D．will come true if the government takes actions

Motherhood may make women smarter and may help prevent dementia（痴呆） in old age by bathing the brain in protective hormones（荷尔蒙） , U．S．researchers reported on Thursday．
Tests on rats show that those who raise two or more litters of pups do considerably better in tests of memory and skills than rats who have no babies, and their brains show changes that suggest they may be protected against diseases such as Alzheimer’s（早老痴呆症）．University of Richmond psychology professor Craig Kinsley believes his findings will translate into humans．“Our research shows that the hormones of pregnancy（怀孕） are protecting the brain, including estrogen（雌激素）, which we know has many neuroprotective （保护神经的） effects,” Kinsley said．
“It’s rat data but humans are mammals just like these animals are mammals,” he added in a telephone interview．“They go through pregnancy and hormonal changes．” Kinsley said he hoped public health officials and researchers will look to see if having had children protects a woman from Alzheimer’s and other forms of age-related brain decline．
“When people think about pregnancy, they think about what happens to babies and the mother from the neck down,” said Kinsley, who presented his findings to the annual meeting of the Society of Neuroscience in Orlando, Florida．
“They do not realize that hormones are washing on the brain．If you look at female animals that have never gone through pregnancy, they act differently toward young．But if she goes through pregnancy, she will sacrifice her life for her infant—that is a great change in her behavior that showed in genetic alterations（改变） to the brain．”
【小题1】How do scientists know “Motherhood may make women smarter”?

A．Some researchers have told them．

B．Many women say so．

C．They know it by experimenting on rats．

D．They know it through their own experience．

【小题2】What does the phrase “litters of pups” mean in the second paragraph?

D．Grown-up rats．

【小题3】What can protect the brain of a woman according to the passage?

A．Estrogen．

B．The hormones of pregnancy．

C．More exercise．

D．Taking care of children．

【小题4】“It’s rat data but humans are mammals just like these animals are mammals．” What does the sentence suggest?

A．The experiments on the rats have nothing to do with humans．

B．The experiments on the rats are very important for animals．

C．The experiments on the rats are much the same on humans．

D．The experiments on the rats are much the same on other animals．

The hole in the earth's protective ozone layer（臭氧层）won't repair itself until about two decades later than had been expected, scientists announced.
The ozone layer blocks more than 90 percent of the sun's ultraviolet radiation（紫外线辐射）, helping to make life on Earth possible. For many dacades, ozone was depleted（削减） by chlorine and bromine gas in the air. A hole in the ozone layer formed over the Southern Hemisphere.
Computer models had forecast that the hole would fill back in by 2050. An improved computer model forecasts the recovery won't occur until 2068. The model, fed with fresh data from statellites and airplanes, was supported by the fact that it accurately reproduced ozone levels in the Antarctic stratosphere（平流层）over the past 27 years.
The ozone hole is actually more of a broad region with less ozone than ought to occur naturally. It is not limited to Antarctica, as is often believed.
Over areas that are farther from the poles like Africa or the US, the levels of ozone are only three to six percent below natural levels. Over Antarctica, ozone levels are 70 percent lower in the spring. This new method allows us to more accurately estimate（估计）ozone-depleting gases over Antarctica, and how they will decrease over time, reducing the ozone hole area.
Paul Newman, a scientist,said that the ozone hole has not started to become smaller as quickly as expected. They figure it will not become much smaller until 2018, after which time the recovery should proceed more quickly. And the hole will not be filled in again until 2065.
【小题1】According to the passage, the ozone layer _______

A．absorbs as much as sunlight as possible

B．protects man against ultraviolet radiation

C．controls the changes in temperature

【小题2】The improved computer model is believable because _________

A．it was once proved by facts

B．it has been studied for 27 years

C．it was created by many scientists

【小题3】The underlined word “they” in the fifth paragraph refers to ________

A．the levels of ozone

B．ozone-depleting gases

C．the ozone holes

D．the areas far from the poles

Nuclear radiation（核辐射）has a certain mystery, partly because it cannot be detected（探测） by human senses. It can’t be seen or heard, or touched or tasted, even though it may be all around us. There are other things like that. For example, radio waves are all around but we can’t detect them or sense them without a radio receiver. Similarly, we can’t sense radioactivity without a radiation detector. But unlike common radio waves, nuclear radiation is not harmless to human beings and other living things.
At very high levels, radiation can kill an animal or human being outright by killing masses of cells in important organs. Even the lowest levels can do serious damage. There is no level of radiation that is completely safe. If the radiation does not hit anything important, the damage may not be serious. This is the case when only a few cells are hit, and when they are killed outright. Your body will replace the dead cells with healthy ones. But if the few cells are only damaged, and if they reproduce themselves, you may be in trouble. They reproduce themselves in an unusual way. They can grow into cancer. Sometimes this does not show up for many years.
This is another reason for some of the mystery about nuclear radiation. Serious damage can be done without the knowledge of the person at the time that damage has occurred. A person can be irradiated（放射治疗）and feel fine, then die of cancer five, ten, or twenty years later as a result. A child can be born weak or easy to get serious illness as a result of radiation absorbed by its grandparents.

To what degree can a computer achieve intelligence？The answer to this question may lie in a newly-developed US computer program called Smarter Child and the Internet.
If you ran into Smarter Child online, you would be surprised at this kid’s huge memory. It can recite many facts. For example, Smarter Child knows every baseball player in every team this season.
He knows every word in the dictionary and the weather in every major city areas across the US. However, if you ask Smarter Child other questions, you get strange answers. A question about Smarter Child’s age returns, “One year, 11 days, 16 hours, 7 minutes, and 47 seconds!” Asking where he lives gets, “In a clean room in a high-tech building in California.”
Smarter Child uses the vast information on the World Wide Web as his memory bank. To answer questions about spelling, for instance, Smarter Child goes to American Heritage Dictionary online. For the weather, he visits www.intellicast.com.
Some scientists believe that by joining the many systems of the Internet, an artificial(人工的) being with the combined knowledge of, say, Albert Einstein, Richard Nixon and Britney Spears could be born. However, if Smarter Child wants to think and learn on his own like the boy-computer David in the movie A. I. Artificial Intelligence, he must solve two problems.
The first is that computers find it difficult to read web pages because the files（文件） are sorted in different ways. That’s why programmers need to tell Smarter Child where to look for the weather. It would be a much more difficult task to let him find it himself.
Another problem is that while Smarter Child can process（处理）information more exactly and faster than any human, he lacks common sense—a basic grounding of knowledge that is obvious to any young child.
【小题1】From the text we can infer that www.intellicast.com is a website          .

A．which is specially designed to help Smarter Child

B．where we people can find Smarter Child

C．where weather forecasts are made

D．which is about artificial intelligence

【小题2】It is probably most difficult for Smarter Child to         .

A．tell us how to spell a difficult word

B．tell us how the American government is run

C．provide us with a famous poem by Shakespeare

D．learn the ability to tell right behaviors from wrong ones.

【小题3】Which of the following is TRUE according to the text?
A. Smart Child has his own memory bank big enough for all kinds of information.
B. A.I. Artificial Intelligence is probably the name of a film about a boy-computer.
C. Smart Child can recognize different files and find information needed on his own.
D. We have similar product now which has the knowledge of Einstein, Nixon and Spears.
【小题4】Which of the following is the best title for the passage?

A．A New Web Child	B．Smarter Child
C．The Future of Internet	D．Intelligence Development

Since the 1970s, scientists have been searching for ways to link the brain with computers．Brain-computer interface（BCI） technology could help people with disabilities send commands to machines．
Recently, two researchers, Jose Millan and Michele Tavella from the Federal Polytechnic School in Lausanne, Switzerland, demonstrated（展示）a small robotic wheelchair directed by a person’s thoughts．
In the laboratory, Tavella operated the wheelchair just by thinking about moving his left or right hand．He could even talk as he watched the vehicle and guided it with his thoughts．
“Our brain has billions of nerve cells．These send signals through the spinal cord（脊髓）to the muscles to give us the ability to move．But spinal cord injuries or other conditions can prevent these weak electrical signals from reaching the muscles,” Tavella says．“Our system allows disabled people to communicate with external world and also to control devices．”
The researchers designed a special cap for the user．This head cover picks up the signals from the scalp（头皮）and sends them to a computer．The computer interprets the signals and commands the motorized wheelchair． The wheelchair also has two cameras that identify objects in its path．They help the computer react to commands from the brain．                                               
Prof．Millan, the team leader, says scientists keep improving the computer software that interprets brain signals and turns them into simple commands．“The practical possibilities that BCI technology offers to disabled people can be grouped in two categories: communication, and controlling devices．One example is this wheelchair．”
He says his team has set two goals．One is testing with real patients, so as to prove that this is a technology they can benefit from．And the other is to guarantee that they can use the technology over long periods of time．
【小题1】BCI is a technology that can         .

A．help to update computer systems
