As a result of pollution, Lake Erie, on the borders of the USA and Canada, is now without many living things.
Pollution in water is not simply a matter of “poisons” killing large numbers of fish overnight. Very often the effects of pollution are not noticed for many months or years because the first organisms (生物体) to be affected are either plants or plankton (浮游生物). These organisms are the food of fish, birds, and other creatures. When this food disappears, the fish and birds die too. In this way a whole food chain can be wiped out, and it is not until dead fish and water birds are seen at the river’s edge or on the sea shore that people realize what is happening.
Where do the substances which pollute water come from? There are two main sources, sewage(污水) and industrial waste. As more detergent (洗涤剂)is used in homes, more of it is finally put into our rivers, lakes and seas. Detergents harm water birds by breaking down the natural substances which keep their feathers waterproof. Sewage itself, if not properly treated, makes the water dirty and prevents all forms of life in rivers and the sea from receiving the oxygen they need. Industrial waste is even more harmful since there are many highly poisonous materials in it, such as copper and lead.
So if we want to stop this pollution, the answer is simple. Sewage and industrial waste must be made clean before flowing into the water reservoirs. It may already be too late to save some rivers and lakes, but others can still be saved if the correct action is taken at once.Pollution in water is noticed ________.

Waste can be seen everywhere in the school. Some students ask for more food than they can eat and others often forget to turn off the lights when they leave the classroom. They say they can afford these things. But I don’t agree with them.
Waste can bring a lot of problems. Although China is rich in some resources(资源), we are short of others, for example, fresh water. It is reported that we will have no coal or oil to use in 100 years. So if we go on wasting our resources, what can we use in the future and where can we move? Think about it. I think we should say no to the students who waste things every day. Everybody should stop wasting as soon as possible.
In our everyday life, we can do many things to prevent waste from happening, for example, turn off the water taps when we finish washing, turn off the lights when we leave the classroom, try not to order more food than we need, and so on. Little by little, everything will be changed. Waste can be stopped one day, if we do our best.Which is not mentioned in this passage?
| A．Fresh water. | B．Forest. | C．Oil. | D．Coal. |
What may happen in 100 years?
| A．We may still have enough oil. |
| B．We may still have enough coal. |
| C．We may have a little oil. |
| D．We may have no coal or oil to use. |
Which of the following is right?
| A．Waste brings problems. |
| B．Waste can bring no problem. |
| C．China is rich in fresh water. |
| D．Students never waste things. |
Which is the best title of this passage?
| A．Stop Wasting |

February 4, 2012 saw the take-off of a new rising NBA star-Jeremy Lin.
Among professional basketball players, Jeremy Lin's background is not typical. He graduated from Harvard University, which sends few players to the NBA, and he is the only Chinese-American NBA player. But when you watch him on the court, there is no doubt that he belongs there. He moves with speed and grace that demonstrate years of faithful practice, which is fueled by a love for basketball.
Lin's enjoyment of basketball actually began in Taiwan. When Lin's father moved to U.S., his interest in the sport only grew and he passed on this love of basketball to his son, introducing him to the game at the age of five. The young Lin spent much of his youth playing basketball for fun.

When he graduated, no professional teams offered Lin a contract, but he was invited to play in the NBA Summer League. He played well and ended up eagerly signing a contract with the Golden State Warriors.
At first，playing in professional games filled Lin with excitement. He treasured opportunities to meet players he had been watching on TV for years. But slowly, the excitementwore offand was replaced by anxiety. In a few very difficult months, he was cut by two teams before the New York Knicks picked him up.
But he had the courage and determination to stick to his dream, so he put himself into hard training to get ready for his opportunity to come. Then his moment arrived on February 4, 2012，on which his excellent performance made him famous overnight. After that, he led the Knicks to their fifth straight victory.
The Associated Press called Lin "the most surprising story in the NBA". Knicks fans developed the nickname for him "Linsanity" (林发疯). Time magazine released its 2012 list of the 100 "Most Influential People in the World", Jeremy Lin included.
