Question: Read the following article and answer the question. Article: The Earth has warmed by about half a degree(0.50degC)over the last 100 years. It could be getting warmer on its own, but many scientists think that people are making the Earth warmer by making a greenhouse effect. The greenhouse effect is important. Without it, the Earth would not be warm enough for us to live on. But just a little warmer than it is now could cause problems for humans, plants and animals. Many of the things we do every day can change the Earth's temperature by sending greenhouse gases into the air. We send greenhouse gases into the air when we watch TV, turn on lights, dry hair, play video games, wash or dry our clothes or drive cars. The rubbish from factories and homes also produces greenhouse gases. Even a small change in temperature can affect our weather. This can cause changes in the sea levels, the air, flooding, and our fresh water. The change in the temperature can also cause changes in the living places for animals and plants, endangering many animals. Global warming is a big problem, and every little bit we do can help. We can save electricity. We can save energy in other ways such as by taking buses or walking rather than driving cars. We can recycle to reduce the rubbish and save natural resources such as trees, oil and metals. We can buy products that don't do bad to the environment and we can turn to solar energy. Remember the little bit that you do will bring a better world. Question: Without the greenhouse effect,we would _ . Answer:
OPTIONS:
- be safer
- not be able to live
- have a cleaner earth
- have a better world
Answer: not be able to live

Question: Read the following article and answer the question. Article: Let's Learn More about Each Other Are the lives of city kids the same as those in villages? In many ways, they are very different. But what are the differences? Hu Peng of Wuhan and four friends decided to find them out. Earlier this month, they lived for a week in Caidian, a village near Wuhan. Hu and his friends went door to door in Caidian and asked the kids there lots of questions. They wanted to learn more about village kids' everyday lives, so they asked these questions like --Do your parents teach you how to do housework? How much money do you usually spend on dinner? What would you do if a thief came into your house? They also asked 150 city kids the same questions.What's the Difference? Last week the team gave a report to their class. There are lots of differences between children's lives in cities and those in villages. The biggest difference is independence. Hu's team said that 60 percent of city kids couldn't do much housework, but 90 percent of village kids could care for themselves. City kids told Hu they cared about school a lot, and they had no time for washing clothes or making their beds. Village kids said they helped their parents with housework a lot. They cooked, did some cleaning and fed animals. Hu's team also found that village kids had less pocket money . Many never used computers. They played in rivers or on mountains. Some didn't really like to make new friends. Hu and his friends said their trip gave them more self-confidence because they were doing something by themselves. But _ also made them a little worried because they saw they still had a lot to learn. "When we grow up, our parents can't take care of us," said Hu. "We have to learn to take care of ourselves." Shen Guanquan, one of Hu's friends said, "When children learn to care for themselves, they learn to do lots of things." Question: They found that most village kids _ . Answer:

Then it hit me that nobody had given up. Instead, everyone had already finished. As I ran that last lap, I cried. And 12 minutes, 42 seconds after starting, I crossed the finishing line. I fell to the ground. I was very upset. Suddenly my coach ran up to me and picked me up, yelling, "You did it. Mark! You finished, son. You finished" He looked at me straight in the eyes, waving a piece of paper in his hand. It was my goal ( ) for the day which I had forgotten. I had given it to him before class. He read it aloud to everyone. It simply said, "I, Mark Brown, will finish the mile run tomorrow, come what may." My heart lifted.
