I watch from the wooden bench in my backyard as the water from the pipe quietly flows out onto the tomato plants. I watch the plants and rest easy, knowing the pipe is taking care of the plants. The drops soon seem to become rivers on the ground.

I see these red-brown ants, crawling(爬行) along around their home. What will happen when the water reaches the ants? Smelling the danger, these poor tiny creatures all run away from the water and rush back to their home. They spend their whole lives working together to create and make better things, but now they are facing the end of it all. I think this is just a reflection of the world. I keep watching as the water first attacks and then surrounds two ants. They struggle to stay floating as the water closes in on them, getting deeper and deeper. I try to get these two to come on my finger, but they refuse to let me save them. The water soon flows over them, as I remain helpless. Only then do they decide to climb onto my dirt-covered finger. Not until facing the moment of death would they trust one like me.

I check to see if they are alive, and both can move fine. Then I go to save other ants. However, the water washes everything away. How much I wish I could turn off this machine of death, but I cannot. I must complete my job.

It knocks me how much these little lives mean to me. When I was a small child, I would make a sport of killing them. Now, I can't hurt an insect, always thinking about what it would be like to be so small.

1.What is the ants' first reaction as the water approaches them?

A. They attempt to stop it.

B. They seek help at once.

C. They ignore it and continue to work.

D. They try to avoid the danger caused by it.

2.What can we infer from the underlined sentence in Paragraph 2?

A. Behind bad luck comes good luck.

B. Where there is a will, there is a way.

C. God helps those who help themselves.

D. Life is likely to be affected by setbacks.

3.How does the author help save the two ants?

A. He turns off the water pipe. B. He helps them float on the water.

C. He lets them climb onto his finger. D. He changes the direction of the water.

4.What's the author's attitude towards those ants now?

Putting in water fountains(ˮ) at schools, and teaching children about the health benefits of water, could reduce their risk of getting extra pounds, reports a new study that is published in the latest issue of the journal pediatrics.

The findings are based on a survey in 32 elementary schools of two German cities, Dortmund and Essen. The researchers, led by Rebecca Muckelbauer, a nutrionist at the Research Institute of Child Nutrition Dortmund, weighed about 3,000 children, and asked them about their beverage() consumption.

At the beginning of the school year, the experts had water fountains added to 17 of the schools. The scientists also worked with teachers to carry out educational programs that promote the benefits of drinking water. In contrast to schools in the United States, there are very few schools in Germany that have water fountains.

At the beginning of the study, there were no big differences in the number of overweight children in different groups. But by the end of the school year, children in the schools with water fountains were 31 percent less likely to gain extra pounds, compared to kids who went to other schools, where water drinking was not encouraged.[Դ:ѧ

Children in the schools with fountains, increased their water consumption from about 3 up to 4 glasses a day, while those in the other schools continued to drink an average of 3 glasses. Over the research, the number of overweight kids upped from 384 to 385 out of 1,641 at the schools with water fountains. In comparison, the number of overweight kids at the other schools increased from 339 to 364 out of 1,309, Dr. Muckelbauer said.

The experts cannot make any final conclusions and explain why the students who were encouraged to drink water were less likely to gain extra weight. Dr. Muckelbauer noted that according to a few other studies, drinking of water increases the rate at which calories are burned, while some other research suggested that water may temporarily decrease appetite.
