根据短文理解，选择正确答案。

Imagine the situation. You are driving along a desert or on a mountain. You have no idea where you are. You passed the last house two hours ago. Then your car breaks down. It is night and it is cold. You have no mobile phone. What do you do? Well, next time take a GPS with you. This invention may be able to help you. It is a device(装置) which uses satellites (卫星) to find the user's position(位置). It can find your position to within 20 metres. A GPS cannot start your car, but at least you will know where you are.

GPS, which means Global Positioning System, is a small radio receiver. It looks like a mobile phone. You can hold it in your hand, or put in your pocket. It is sometimes put into a watch or a telephone. We also find GPS devices in cars, planes, or boats. Some of these devices have electronic maps, so you know where you are. For example, in a city they can tell you the name of the street.

There are three parts to the Global Positioning System. The first part is the receiver. You can hold it in your hand, or have it fixed into your car, plane, etc. The second part is a group of satellites orbiting the Earth. The receiver contacts at least four of the satellites and calculates(计算) its position. The third part of the system is a network of ground stations. They are all over the world. They control the satellites and make sure they are working well.

Some people think that in the future the GPS will be as common as the mobile. They are becoming cheaper and more and more accurate(精确的). There are also new uses for the GPS. Perhaps they will become like watches. Everyone will have one and you will never be lost again.

（1）、According to the passage, with the help of the GPS, people __________.

A、can't be lost in a new city B、can't find their way in different countries C、can learn about the culture of an unknown place D、can spend the least time getting to another place

（2）、We can learn from the passage that ____________.

A、there are three parts to the GPS B、a GPS can't be put into a watch C、a GPS can help you start your car D、the GPS are becoming more and more expensive

（3）、The underlined word “They” in paragraph 3 means “____________”.

A、Receivers B、GPS devices C、Satellites D、Ground stations

（4）、The passage is mainly about _______________.

A、the history of the GPS B、the introduction of the GPS C、the shape of the GPS D、the three parts of the GPS

（5）、What can we infer(推断) from the passage?

A、All GPS devices have electronic maps. B、People in many countries will use the GPS for free. C、The receiver of the GPS contacts at least five of the satellites. D、The GPS will become more and more common in everyday life.

   Do you know that women's brains are smaller than men's? Normally the women's brain weighs 10% less than men's. Since research has shown that the bigger the brain, the cleverer the animal, men must be more intelligent（聪明的） than women. Right? Wrong. Men and women always score similarly on intelligence tests, despite the difference in brain size. Why? After years of study, researchers have concluded that it's what's inside that matters, not just the size of the brain. The brain is made up of “grey matter” and “white matter”. While men have more of the white matter, the amount（数量）of “thinking” brain is almost the same in both men and women.
   It has been suggested that smaller brain appears to work faster, perhaps because the two sides of the brain are better connected in women. This means that little girls may learn to speak earlier, and that women can understand sorts of different information at the same time. When it comes to talking to the boss on the phone, cooking dinner and keeping an eye on the baby all at the same time, it's women who come out on top every time.
   There are other important differences between two sexes（性别）. As white matter is the key to spatial（空间的）tasks, men know better where things are in relation to other things. “A great footballer always knows where he is in relation to the other players, and he knows where to go,” says one researcher. That may explain one of life's great mysteries: why men refuse to ask for directions … and women often need to!
   The differences begin when fetuses（胎儿）are about nine weeks old, which can be seen in the action of children when they are very young. A boy would try to climb a barrier before him or push it down while a girl would ask for help from others. These brain differences also explain the fact that more men take up jobs that require good spatial skills, while more women speech skills. It may all go back to our ancestors, among whom women needed speech skills to take care of their babies and men needed spatial skills to hunt, according to one research.

When on the go or traveling, a Disposable(一次性) Toothbrush might be just the product for you, Typically, a Disposable Toothbrush is made out of a plastic material, with toothpaste already on the brush head. Just add water while you are using it. In some new Disposable Toothbrush models, the toothpaste comes automatically(自动地) as you squeeze (挤) the handle of the toothbrush.

Colgate has upped the competition in the Disposable Toothbrush market by creating a Disposable Toothbrush that you can use at your desk at work, in your car, or after eating at a restaurant. This toothbrush is called the Colgate Wisp, and is about the size of an index finger. The toothbrush can get to those places that are hard to reach just like a regular toothbrush. No water is necessary when using this toothbrush, making it very useful and convenient. A pack of four of the Colgate Wisp's run at about $2.99. If you are one of those people that like to brush your teeth throughout the day but hate the hassle of carrying a toothbrush and toothpaste around, this is perfect!

Gadgets.boingboing.net is a website that allows different people to share their thoughts and experiences on a certain product. The website gives a general review on the Colgate Wisp，and following the review, people are able to share their first-hand feelings with readers. This is helpful if you are interested in purchasing the Wisp. Visit their website here: gadgets.boingboing.net.

However, people throw them away after using them only once. It is a kind of waste and is very bad for the environment. If you travel to Beijing， remember to bring your own things. Starting from June, some hotels in Beijing will no longer provide guests with these disposable goods.

Have you ever noticed how，on a rainy night，all other sounds seem to disappear? The sound of the rain drowns （淹没） them out. And even though the sound of the rain goes on all night，it doesn't keep you awake. Rain is a kind of white noise﹣a steady and unchanging sound.

White noise is made up of sounds from all the frequencies （频率） a human ear can hear，with the sound at each frequency having the same power. It's called "white" because it is like that of white light，which is a mixture of all the light we can see.

You might think that a mixture of all possible sound frequencies would be terrible，but it's not ﹣ quite the opposite. The reason for this is that white noise covers other sounds. Think of it like the rain：the sound of one drop falling，like from a leaky tap （漏水的龙头），would be very different and hateful. Two drops would be the same. You could even tell three drops apart. But if there were 5 or 10 or 1，000，you couldn't pick out each drop. They'd all mix into a kind of quiet sound and probably lead you to sleep.

According to a scientific study，white noise can help treat different problems. It can help worried people sleep and help those who have headaches sleep through their pain. It can be very useful for people with attention problems，who have trouble telling background noise and can't focus on something well. White noise can help them pay attention to something. It can even cover the sound of conversations by doctors and others who want to keep privacy. Who would have thought that mixing lots of sounds together would actually turn out to develop peace and quiet?

Sleep experts often say that for a better night's rest, people should turn off their smart phones or iPads before sleeping. Such electronic {#blank#}1{#/blank#}(产品) make the brain more active, and then influence their sleep. But according to a latest survey, {#blank#}2{#/blank#} (几乎)15% of people often use computers or smart phones in the hour before bed.

In the {#blank#}3{#/blank#} (项目), the researchers {#blank#}4{#/blank#}(分开) the volunteers into three groups and asked then to read, play games and watch movies on a screen for different time while measuring how much light their eyes {#blank#}5{#/blank#}(收到). They found that two hours of sitting before a bright screen at night made the sleep chemical levels drop by about 22%. Then the researchers studied the college students who spent a long {#blank#}6{#/blank#}(一段时间) of time on computers at night. They got the similar result without {#blank#}7{#/blank#}(疑问). And researchers said that might not only cause sleep- lessness, but also {#blank#}8{#/blank#} (增长) the risk of obesity(肥胖症), diabetes(糖尿病) and other diseases.

To be on the safe side, the researchers suggest that we should use computers {#blank#}9{#/blank#}(明智地). In the {#blank#}10{#/blank#} (日常的) life, we'd better turn down our screens as much as possible before sleeping.
