Global warming is when the earth heats up，the temperature rises.It happens when greenhouse gases—carbon dioxide，water vapor，nitrous oxide (二氧化氮)，and methane (沼气) 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 very 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.Once the light is inside the car，it is trapped and the heat builds up，just like it does in the earth’s atmosphere.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 on the other hand it would be burning hot.We would not get the sun’s heat and light to make the night somewhat warm.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 earth can get unusually warmer，and many plants，animals，and people will die.They would die because there would be less food (plants like corn，wheat，and other vegetables and fruits)．This would happen because the plants would not be able to take in the heat.This would cause us to have less food to eat，but it would also limit the food that animals have.Gradually，people，plants，and animals would all die of hunger.
People are doing many things to try to stop global warming.One thing people are doing is carpooling.Carpooling is driving with someone to a place that you are both going to.This minimizes the amount of greenhouse gases put into the air by a car.
Another thing that people are doing is being more careful about leaving things turned on like the television，computer，and the lights.A lot of people are taking time away from the television，and instead，they are spending more time outdoors.This helps our planet out a lot.Now，more people are even riding buses，walking to school，and riding their bikes to lower the amount of greenhouse gases in the air.
Planting trees and recycling also help.If you recycle，less trash goes to the dump，and less trash gets burned.As a result，there are fewer greenhouse gasses in our atmosphere.Although adults do many things to help stop global warming，kids can do just as much.The underlined word “it” in Paragraph 2 refers to________．

Of all the things we eat and drink, water is the most important. Not all people realize this, but it is quite true. The human body can live without food for a long time, but two or three days without water usually result in death.
Many people do not understand how much water the human body needs, but many people do not drink enough, especially in the hot weather. Most people drink when they are thirsty but often need more water after exercises.
65 to 70 percent of the human body is water. Water is important in several different ways. Most people need five to seven liters（升） of water every day, but we needn’t drink this amount(量) because a lot comes from the food we have. If we don’t have enough water, however, we will feel tired and many become ill. Do you know what the best drink is? Yes, you are right. Cool water!When do we need more water?________

When I was growing up, I was embarrassed to be seen with my father. He was badly crippled (跛脚), and when we would walk together, his hand on my arm for balance, people would stare, I would be ashamed of the unwanted attention. If ever noticed or bothered, he never let on.
It was difficult to walk together—and because of that, we didn’t say much as we went along. But as we started out, he always said, “You set the pace. I will try to follow you.”
Our usual walk was to or from the subway, which was how he got to work. He went to work sick, and even in bad weather. He almost never missed a day, and would make it to the office even if others could not. It was a matter of pride for him.
When snow or ice was on the ground, it was impossible for him to walk, even with help... Such times my sister or I would pull him through the streets of Brooklyn, N.Y., on a child’s sleigh to the subway entrance. Once there, he would try to grasp handrail until he reached the lower steps that the warmer tunnel air kept ice free. In Manhattan the subway station was the basement of his office building, and he would not have to go outside again until we met him in Brooklyn on his way home.
When I think of it now, I am surprised at how much courage it must have taken for a grown man to suffer from shame and disability. And I am also surprised at how he did it—without bitterness or complaint.
He never talked about himself as an object of pity, not did he show any envy of the more fortunate or able. What he looked for in others was a “good heart”, and if he found one, the owner was good enough for him.
Now that I am older, I believe that is a proper standard by which to judge people, even though I still don’t know exactly what a “good heart” is. But I know the times I don’t have one myself.
He has been away for many years now, but I think of him often. I wonder if he sensed my reluctance to be seen with him during our walks. If he did, I am sorry I never told him how sorry I was, how unworthy I was, how I regretted it. I think of him when I complain about my troubles, when I am envious of another’s good fortune, when I don’t have a “good heart”.How did the man treat his father when he was young?
| A．He helped his father happily. | B．He never helped his father. |
| C．He helped his father, but not very happily. | D．He only helped his father take a walk after supper. |
As a disabled man, his father____.
| A．didn’t work very hard | B．didn’t go to work from time to time |

| A．anger | B．sadness | C．happiness | D．unwillingness |
How did the father get to work usually?
| A．By subway. | B．By bus. | C．By wheelchair. | D．By bike |
The income gap between China's rural and urban residents(居民) has continued to widen during the past few years in spite of rapidly rising rural incomes, Agricultural Minister Sun Zhengcai said here on Wednesday.
The income ratio(比率) between urban and rural residents was 3.28:1 in 2006, against 3.23:1 in 2003, said Sun in his report on the promotion of building a new countryside in 2007. Sun also said the net income of rural residents in different regions also varied widely. The income gap is only one of several problems in rural areas, according to Sun's report. While listing the achievements in rural areas in recent years, Sun believed that rural development still followed behind urban development.
"We have bigger pressure to ensure the supply of major agricultural products such as grain," he said. "China's urbanization(都市化) has been speeded up and more rural residents have gone to urban areas," he said.
"In this case, more agricultural producers become farm produce consumers, which created more pressure for supply," he said.
Another problem facing China's agricultural development is inadequate application of science and technology.
"Only 30 percent of scientific and technological achievements have been applied to agricultural production, which is 40 percentage points lower than developed countries," he said.
Despite increased government spending in rural areas, the infrastructure(基础下部组织) is still poor and easily hit by disasters.
According to Sun, the government spent 431.8 billion yuan ($59.15 billion) on agriculture, rural areas and farmers this year, an increase of 80.1 billion yuan over the previous year.
China set aside 11.38 billion yuan to promote a new rural cooperative medical care system and 27.98 billion yuan to support the new compulsory education mechanism in rural area to ensure that all citizens shared the fruits of China's reform and opening-up, Sun said.Which of the following is TRUE according to the text?
| A．Because of the rapidly rising rural incomes, the income gap between China's rural and urban residents will disappear this year. |
| B．The net income of rural residents in different regions is the same. |
| C．The government has taken measures to develop the economy in the rural areas. |
| D．Because of the rapidly rising rural incomes, the supply of major agricultural products is enough. |
Can you infer the meaning of the underlined words in paragraph 5?
| A．be made full use of | B．be made little use of | C．be not made full use of | D．be made good use of |
How much is spent on agriculture, rural areas and farmers the previous year?
| A．431.8 billion yuan | B．511.9 billion yuan | C．351.7 billion yuan | D．80.1 billion yuan |
Which is NOT the problem in rural areas?
| A．The income gap | B．The inadequate application of science and technology |
| C．The supply of major agricultural products | D．China's urbanization |
A common misconception (误解) -about scholarships is that they are only available for the smartest students with the highest GPAs. However, this just isn't even close to true. There are scholarships out there for every type of student seeking a college education. Let's take a look at each type a bit more in depth.
Academic Scholarships
Academic scholarships are also often referred to as merit (优点) scholarships, though a merit scholarship can mean anything that has some level of contest to it. These are fox; the students with the 4.0 GPAs, the years as a part of several extracurricular (课外的) activities and the well- rounded applications. They typically have the highest payouts and are considered very well- known as they are often national awards.
Athletic Scholarships
For students with strong academics (学业的) and physical skills, athletic scholarships are the way to go. There is practically a scholarship for every single sport, from volleyball to football; gymnastics to cheerleading. So, if you are good at anything physical, you should definitely pursue an athletic scholarship.
Scholarships for Minorities
There are also many scholarships for minorities available. Some of these are general and for "all minorities as a collective whole, while others are intended for individual ethnic (种族的) groups. It is also a good idea to apply for a minority scholarship if you are part of fully of a certain ethnicity. You will get to represent your culture and possibly win money -- what more could you ask for?
Scholarships for Women
As with the scholarships for minorities above, there are also scholarships specifically for women. Since colleges were dominated (主宰) by men for many years, scholarships have been created for strong, career-minded women that need assistance paying for college expenses. If you are female, it is strongly recommended you pursue a scholarship for women. Moreover, scholarships for women are typically available in just about any field. Be specific!

Dr. Julie Coulton, a British psychologist, focuses her research on the extraordinary function of the play in the physical and spiritual development of children and Martti Bergson from the University of Helsinki shows that playing outside, in the open air, contributes to a better development of the brain.
Thus parents must encourage their children to spend as much time as possible in the open air, and at the same time, to ask schools and kindergartens to assure the small a playground outside. Recent statistics (数据) and studies show an alarming increase of the number of hours spent by children in front of the TV and the computer and a decrease of the time spent outside.
As a consequence more and more children suffer from eye problems and have to wear glasses. Also the problem of fatness among children concerns many parents who don't know what to do anymore to make their children eat healthy and balanced.
Children need a space where to develop their creativity mid parents should encourage them all the time. Too many rules hold back the child's personality and creativity and prevent them to develop the desire to know, to find out, to learn.
If you tell your child so many times: "Don't do that, don't mess the room, don't go there ...", he will lose the desire to do something, anything. Parents must watch their children without suffocating (窒息) them. Should you consider they mustn't do that or this, you have to logically explain them your reasons and they will understand.
Through playing a child learns how to communicate, how to take decisions. Playing is connected to the intellectual, emotional and social progress of the child. Playing lets your children learn how to express his feelings.What is worrying the scientists is that ______.
| A．most parents pay no attention to their children's playing |
