Who's building the new China? It's not the factory owners or the business men and women of China. It's someone else. We see them every day, They work day and night in the terrible working conditions and weather. They build the roads, the theaters, the cinemas and the supermarkets. They even clean up our rubbish. They are China’s migrant workers(民工).
More than 140 million workers have left their homes in the countryside to look for jobs in big cities all over China. They hope to be rich, but they realize they have many difficulties in making enough money. And one of the difficulties that these workers have is the pride and discrimination (歧视) from the people in cities. When night falls, everywhere I look I see the sad faces of the migrant workers. Many are living far away from those whom they love. Yes，they dress differently, they speak differently, and they have different habits, but they work hard .The people in cities regard them as outsiders, and most governments refuse to give them medical care and public schooling for their children. If China hopes to move into the future, many things need to change. The first is discrimination! We need to stop our discrimination against the migrant workers of China! They may not make as much money as some people in cities, but they are good honest people just trying to survive this game of life. These workers are very important and necessary to China’s economic (经济) development and have become an important force for the change of Chinese society. They are building the new China, so we should help them.

The weather is getting hotter. You are thirsty playing basketball or riding home from school. A cold drink may be just the thing. But be careful what you are drinking. Something that looks cool may not be good for your health.

There are plenty of "energy drinks" on the market. Most of them have beautiful colors and cool names. The lists on them tell you they are helpful to your health. Sounds great!

But after a careful check you may find that most energy drinks have lots of caffeine (咖啡因) in them. These drinks are especially aimed at young people, students, busy people and sports players. Makers sometimes say their drinks make you better at sports and can keep you awake. But be careful not to drink too much.

Caffeine makes your heart beat fast. Because of this, the International Olympic Committee has limited( 限制) its use. Caffeine in most energy drinks is at least as strong as that in a cup of coffee or tea. Possible health dangers have something to do with energy drinks. Just one box of energy drink can make you nervous, have difficulty sleeping and can even cause heart problems. Scientists say that teenagers should be discouraged from taking drinks with a lot of caffeine in them.

When people want to know about the weather, they usually go to their radios, TVs, newspapers, or to the Internet. However, you can also find many weather signs among wildlife, because of their highly developed senses. Drops in air pressure produce an effect on small animals in many ways. Mice and deer are good weather indicators. People who spend a lot of time outdoors have observed that, before a storm, field mice come out of their holes and run around. Deer leave high ground and come down from the mountains.

Birds are especially good weather indicators because they also show the effect of a pressure drop in many ways. For example, some birds become irritable(暴躁) and quarrelsome and will fight over a piece of bread. Other birds chirp and sing just before a storm. It seems they know they won’t get another chance for an hour or two. Birds also look for safe places before a storm. You will sometimes see birds settling in trees or gathering together on a wire close to a building. Pre-storm low pressure make the air so thin that birds have difficulty flying.

It is unusual to see many birds flying overhead in the summertime, rather than during the periods in the spring or autumn. Watch for other weather signs if you see this. If they fly in the wrong direction, they may be flying ahead of a storm.

By paying closer attention to some important signs in nature, we can become better prepared for any kind of weather.
