Book 2

Unit 1

Time is a Precious Resource

As a popular saying goes, "Time is money.” In fact, time is more precious than money. When money is spent, you can earn it back if you want to. However, when time is gone, it will never come back. As the pace of modern life continues to accelerate, the time at our disposal is quite limited.

But there are a lot of things to be done in our lives. We should make full use of our time to fulfill what is useful to us. For instance, as students we should devote most of our time to our academic studies. In this way we can acquire new knowledge and skill necessary for our future carrier.

In my opinion, wasting time means wasting our valuable life. But many of us don't realize this. They think time is inexhaustible. I'm not in favor of such of a view. Hence, my conclusion is that we should never put off what can be today until tomorrow.

Fight against Gun Crimes

Today the crime rate in some cities of our country is rising. Many citizens often complain about the thefts, robberies and even gun crimes that have taken place in the areas they live in and appeal to the governments at all levels to take effective measures to reduce the crime rate.

Faced with criminals, some people are so frightened that they shamelessly give up the fight and other people turn a blind eye to them. However, some people are brave enough, to risk their

lives to fight the criminals. Their fearless actions prevented the criminals from doing evils, saved the victims, and protected the public properties.

To reduce the crime rate, we all the people should first receive a law education. Criminals must be severely punished. Meanwhile we should set up a foundation to reward those who fight criminals. It is also important to call on people to learn from those heroes and encourage more people to stand up to crime.

Against Populating Explosion

The large number of our population has become one of the most serious problems of our society. According to a recent survey of the National Bureau of Statistics, there are more than 1.3 billion people in our country which account for about 1/5 of all the people in the world. The same survey also predicts that our population will grow quickly in the years to come.

Overpopulation has brought about a series of negative effects to our economic development and social security. In the first place, too many people impose a heavy burden on our environment. As a result, we suffer from a shortage of fresh water and natural resources. In the second place, as the supply of labor greatly exceeds the demand of the society, many people become employed. This is a source of social unrest. Last but not the least; we have to meet the needs of the people, which cause environment pollution to our lakes and land.

Serious though the problem seems, we have to take some measures

to tackle it. On the one hand, the government should carry out more strictly the poli cy of family planning, thus reducing the total number of population. On the other hand, all the people should realize the harms of overpopulation. With the concerted

efforts of all the parties concerned, we’re sure to solve the problem in the future.
