Tracking Stations
One night in February 1962, John H. Glenn, Jr., flew over Australia. The man in the Mercury（水星）capsule（宇宙飞行容器）was alone, but friendly voices reached him by radio. Over the dark land 100 miles below, he saw sparkling lights. It marked the city of Perth, where people had turned on their lights as a greeting to him.
"In Friendship 7," Glenn radioed, "the lights show up very well. Thank everybody for turning them on." His capsule needed on to the east.
During his three orbits of the earth, Glenn could always reach one of the eighteen tracking stations. Some of them were on ships at sea. Others were in the United States.
Many of the stations had been built with the help of other countries. These countries allowed Americans to bring in radio equipment and set it up. Without the help of such lands as Nigeria, Zanzibar, and Mexico, there would have been breaks in the worldwide radio network. John Glenn, Jr., was the first American to orbit the earth. For his flight, the tracking network（跟踪网络）covered 60,000 land or statute miles（法定英里）. Five hundred men worked in the stations along the route. Since his flight, the network has grown. Today, it covers more than 100, 000 statute or land miles and has about one hundred stations. One-third of these stations are outside the United States.

How to deal successfully with a child showing outstanding musical ability? It’s not always clear how best to develop and encourage his gift. Many parents may even fail to recognize and respond to their children′s need until discouragement explodes into uncooperative(不合作的)behavior. And while most schools are equipped to deal with children who are especially able in academic subjects，the musically gifted require special understanding which may not always be available in an ordinary school. Such children may well benefit from the education offered by a specialist music school.
The five music schools in Britain aim to provide all environment where gifted children can develop their skills under the guidance of professional musicians. Children here spend about half of a day on musical activities，for example，individual lessons，orchestras，chamber(室内音乐的)groups，voice training，conducting and theory. They also spend several hours a day practicing in private rooms .The rest of their time is taken up with the subjects：English，maths and basic sciences.
What are the disadvantages? An obvious problem is that the fees are high .However, each school will often scholarships and other forms of financial aid. Secondly, not all parents want to send their children to boarding school, especially at an early age .Almost all the directors of the specialist schools express doubts about the wisdom of admitting children as young as seven into such a tense and disciplined（守纪律的)environment. They stress，however, that their main aim is to turn out “well-rounded and well—balanced individual.”If a child’s musical ability is not recognized___________.

Water runs downhill from mountaintops to streams to rivers to oceans. But downhill isn’t the only way that water moves .A new study measures how water travels from country to country for human consumption. This flow isn’t the type we usually think about .These scientists looked at the water used to grow and make the products which get shipped from nation to nation as imports or exports. They call this a flow of“virtual water（虚拟水）”.
We typically think about water as the liquid that flows from a tap. However,92％of the water used by people goes into growing crops，according to water researcher Arjen Hoekstra. He recently studied the hidden travels of virtual water used in products made from things like crops and meats .These products are shipped around the world.
For example．consider a sugary soft drink. Hoekstra estimated that to produce one half-liter of the drink requires between 170 and 310litersofthewater—about 95％—is used to grow and process the ingredients(原料).Another 4％goes into the packaging and labeling. In Hoekstra’s calculation, when one country produces a half-liter of soda and sells it abroad，it exports as much virtual water as would fill a large refrigerator．
According to Hoekstra’s new report，dry countries like Israel and Kuwait，both in the Middle East, get the majority of their virtual water from other countries，through imported products. More surprisingly, some wetter countries，like the Netherlands and the United Kingdom, also get the majority of their virtual water from other places. That means that most of the water used to grow or produce the products and food consumed in those countries came from other countries.
In the United States most of the virtual water used comes from American sources .In China even less of the water associated with its productsWhat is the best title for the passage?

Global warming happens when greenhouse gases trap heat and light from the sun in the earth’s atmosphere, which increases the temperature. This is like when heat is trapped in a car. On a hot day, the car gets hotter when it is out in the parking lot. This is because the heat and light from the sun can get into the car, by going through the windows，but it can’t get back out. This is what the greenhouse effect does to the earth .The heat and light can get through the atmosphere, but it can’t get out As a result，the temperature rises.
Sometimes the temperature can change in a way that helps us. The greenhouse effect makes the earth appropriate for people to live on Without it，the earth would be freezing，or it would be burning hot. It would be freezing at night because we would not get the sun’s heat and light .During the day, especially during the summer, it would be burning because the sun would be up with no atmosphere to filter(过滤)it，so people，plants，and animals would be exposed to all the light and heat.
Although the greenhouse effect makes the earth able to have people living on it，if there gets to be too many gases，the each can get unusually warmer, and many plants，animals．and people will die. Plants would die because they would not be able to take the heat .This would cause us to have less food to eat, and it would also limit the food that animals have. With less food for the animals that we need to survive we would even have less food. Gradually, people，plants，and animals would all die of hunger．
People are doing many things to try to stop global warming .One thing is carpooling—driving with someone to a place that you are both going to. Another thing is being more careful about leaving electrical devices turned on. Now, more people are even riding buses or bikes to lower the amount of greenhouse gases in the air .Although adults do many things to help stop global warming, kids call do just as much.By the example given in Paragraph l, the author wants to__________.
| A．explain how global warming happens |
| B．show his feeling in a car in hot summer |
| C．tell us cars are causes of greenhouse gases |
| D．say that I there are greenhouse gases in every car |
The underlined word ‘it” in Paragraph 2 refers to__________.
| A．light | B．greenhouse effect | C．temperature | D．heat |
What is the effect of atmosphere?
| A．IT only traps the heat of the sun. |
| B．It does great harm to humans. |
| C．It makes the earth neither to hot nor too cold. |
| D．It prevents all the light from the sun shining on the earth. |
What is the main idea of the third paragraph?
| A．lf there is greenhouse effect．all the plants will die |
| B．Human beings are likely to disappear from the earth |
| C．Crops can’t take in the heat lf there is greenhouse effect |
| D．Although greenhouse effect is necessary．Too much of it will cause us to die. |
What will the author most probably discuss in the paragraph that follows?
| A．What kids can do to help stop global warming. |
| B．Who should be responsible for the environmental problems. |
| C．What global warming is doing to the environment. |
| D．Why cars and buses pollute the air a lot |
Ashok Gadgil has spent the past three decades helping people in need—and he has no plans to stop .On May 2, Gadgil won the$100．000 Lemelson-MIT Award for Global Innovation. Each year，the honor is given to an inventor who has improved the lives of people in developing countries. Gadgil‘s inventions have helped more than 100 million people around the world.
Gadgil is a professor and physicist at the University of California. When he’s not teaching，he works to find solutions to global problems such as energy efficiency and water safety. “I chose to focus on problems where my knowledge of science could help，”he said
In the 1980s he came up with a program to make energy-efficient light bulbs more affordable for people in developing countries. Then in the 1990s，Gadgil designed his first life—saving invention，UV Waterworks .The device kills deadly disease —carrying germs(病菌)from drinking water. It costs just one cent to clean five liters of water .Gadgil was inspired to find an inexpensive solution to the clean water crisis after more than 10，000 people in his home country of India died from an outbreak of Bengal cholera，in 1993 The disease is spread through contaminated food and drinking water .So far，the invention has provided safe drinking water to more than five million people in poor areas.
As a professor，Gadgil encourages his students to stay positive about finding solutions to hard problems.“Be optimistic when you try a hard problem．”he says. “It’s when you solve a large problem that you can have a big impact on the world”Gadgil was given Lemelson-MIT Award for___________.

If you're like a lot of married guys, you don't need to be reminded about men being from Mars or women from Venus. Chances are that you're all too familiar with the feeling that you and your wife are from different worlds. When married people start noticing their fundamental differences, it can lead to a breakdown in communication. The way to have a successful marriage is through communication, common ground and understanding. Here are some pointers to guide you in the right direction.
Rather than ending up in an endless back and forth, forget about the issue for a minute. Instead, think about how you feel she's acting toward you and ask her if that's how she feels about you. If you think she's being unfair, ask her if she thinks you're being unfair. Switching the focus to that shared feeling can help your wife see things from your point of view.
It's important to accept the fact that there's a two-way street between you and your wife. If you think she doesn't make enough of an effort to see things from your point of view, you have to ask yourself if you're making an effort to see it her way.
Realize nobody can wave a magic wand to make you and your wife completely understand each other all the time. Many couples have an extremely close friendship and do almost everything together before they're married. Once you've tied the knot, you may begin to notice that you're not as alike as you once thought.
It seems obvious, but some guys get fooled into thinking their wife will be as excited about all of their interests and hobbies as they are. Don't be surprised when you find out that she's not just like "one of the guys." Sooner or later you'll realize that she might be going along with some of your interests just to make you happy.
Rather than feel offended if you find out she's not as into your favorite hobby as you thought, appreciate the effort she put into making you happy. Swallow your pride and try to take part in some of her hobbies, too, even if you might be a little put off at first. While you're not going to be trying on makeup with her, you could try baking a recipe together.
If either of you is always giving everything and getting nothing in return, there's going to be bitterness. The best marriages are built on compromise. You knew you were going to have to give and take for your marriage to work; now it's time to make it happen.What is the best title of the text?

| C．She won't always understand you (but that's OK). |
| D．Try to understand each other all the way. |
