【正文】 nd everincreasing pressure, people in mounting numbers are suffering either physical or mental problems. It is universally acknowledged that good health is the key to a happy life and a successful career. 愛上你視頻網(wǎng)： 天天好資料，免費下載 There are numerous ways of keeping fit. First and foremost, it is most effective to do physical exercises. People respectively choose jogging, playing basketball, swimming, skating, climbing or riding as their regular exercises in that exercises never fail to make us stronger and more energetic. Moreover, we should put geat emphasis on forming good habits. A balanced diet and sufficient sleep are both indispensable to physical fitness. More importantly, mental health should also be taken seriously. Especially in adversity, we need to maintain an optimistic mentality to pull through life’s pain and sorrow, twists and turns. As far as I am concerned, I have a peculiar interest in yoga exercise. An hour’s exercise every day usually makes me feel healthier and more vigorous. Besides, I never touch any cigarette or wine, neither do I stay up late. Instead, I keep a balanced diet and go to bed before 11 o’clock at night for I suppose buring the midnight oil is harmful to health. What is more, an optimistic attitude toward life makes me confident and persistent. To sum up, all these practices guarantee a fit health and a happy life. (236) 7. The majority of people would agree that cigarette smoking has caused serious problems. But the tobacco panies insist that they contribute greatly to the world economy by paying taxes to the government and employing hundreds of workers. Personally, I believe that cigarette production and consumption threatens to do more harm than good. Firstly, smoking is responsible for many fatal diseases such as lung cancer, heart diseases and so on. According to the survey, tobacco consumers account for about 20% of the world population, and among them, three million people die from smokingrelated diseases every year. The fact that the output of tobacco production is reduced from billion pounds in 1994 to 142 billion pounds in 1995 also suggests that people have e to realize the negative effects of smoking. Secondly, tobacco consumption is extremely wasteful of money. As is indicated in the pictures, 200 billion US dollars is lost due to smoking each year. Obviously, the total loss of money around the globe substantially exceeds the gain in the industry. In conclusion, as the economic development aims at making our life better, we cannot sacrifice our health for shortterm financial benefits. If we have to spend more and more money providing medical services for those who suffer from smokingrelated illnesses, the notio n of promoting economy via tobacco production is not justifiable. It is high time that we fought for the total tobacco ban. As can be seen from the humorous cartoon, a hen, while laying eggs, is proudly promising that her eggs are all normal and ovalshaped rather than twisted. Besides, they all consist of shells, egg whites and yokes. Since the hen is emphasizing a simple fact known to everyone, the promise sounds rather meaningless and queer. Undoubedly, the drawing has symbolically revealed a serious problem in our daily life, the widespread meaningless promises made by people from all walks of life. In particular, some profitdriven enterprises take advantage of such promises to win people’s trust and favor. Although their products have nothing to remend, they present misleading advertisements and deceptive descriptions to exaggerate their ordinary work. Similarly, some individuals, obsessed with fame and success, try every means to publicize their deeds, but actually they are just assuming their 愛上你視頻網(wǎng)： 天天好資料，免費下載 duties. Such empty promises and boasts will definitely do great harm to people as well as to the society. Hence, Measures should be taken to terminate the ridiculous practices. For one thing, authorities should establish some regulations to prohibit enterprises and people from making such promises. For another, people should get ready to pass criticism upon empty promises anytime and anywhere. After all, it is imperative to develop our society by performing hard work instead of talking nonsense. (215) 9. The two charts show that the increase in the . population has been acpanied by a corresponding decline in the number of wildlife species. Far too many species have been lost already. This poses a danger to the ecological balance. As the human population expands, wild animals in mounting numbers are hunted for food, or because they are thought to present a threat to man. But studies show that one of the primary causes of the disappearance of wildlife is pollution, which is one of the consequences of population growth and economic development. This makes us wonder if men are able to share this pla in harmony with other life forms. In my opinion, it is imperative for us to take steps to reverse the disturbing trend illustrated in the charts. One measure would be to forbid the building of cities in areas where wild life is threatened with extinction. But, more importantly, men must learn to stop polluting the environment, or he himself will be extinct. （ 167） 10. As is shown in the pictures, we can see clearly that with the increase of mercial fishing, the number of fishes sharply decreased. In one picture, there were various kinds of fish and only one fishingboat in 1900. On the contrary, in 1995 there was only one fish, but many fishingboats. The purpose of this picture is to show us that due attention has to be paid to the decrease of ocean resources. Owing to overfishing, the number of fishes has obviously decreased. If we let this situation go as it is, we won’t know where fish is in the future. By that time, our environment will suffer a great destructio
