假如我是科学家，我要发明一种神奇的书，书上不但有文字，还能把文字变成语言。看的时候，那一行行文字就会变成娓娓动听的话语。到那个时候，人们就能在黑暗之中捧着书来学习了。把这种书送给老奶奶、老爷爷们，他们可以不用戴老花镜看了。假如我把这种神奇的书送给盲孩子们，他们就会轻松地学习了，书会把他们带到另一个世界里。在那里他们可以快乐地学习，无拘无束地吸取能量。
假如我是科学家，我还要发明一种随着天气变化的墙纸。春天，墙纸会变成淡蓝色，上面印有小鸟的图案，它们在蓝蓝的天空下快活地飞来飞去，唱着动听的歌曲，真让人陶醉，人们在优美的环境下轻松地工作。夏天，墙纸会变成一片深蓝，蓝天下有一片荷花池，在池中，一朵朵粉红色的荷花像是一位位亭亭玉立的姑娘随着微风轻轻摇摆。一片片荷叶仿佛是一艘艘小船。小姑娘坐在小船之中，正在采莲蓬。池水倒映着荷花，让人分辨不出哪些是花，哪些是人影。秋天，墙纸变成金黄色，稻田里的稻穗成熟了，把腰都笑弯了。冬天，墙纸变成白色，上面有几个小朋友在雪地上滑雪……
从现在开始，只要我刻苦学习，努力攀登科学的高峰，我的愿望就一定会实现的。

When holiday comes, thousands of people pour into the tourist sites, they want to relax themselves and enjoy the beautiful scenery. But Chinese people have a bad habit, they like to leave some notes on the site, proving them have been here before. Such a behavior has been criticized by the public, because the leaving note will damage the preservation of the tourist site. Most of the tourist sites are part of our country's historical relics, these sites are priceless, it is everyone's duty to protect the sites. When we go to travel, we should behave ourselves. First, we need to have the idea that no rubbish being leaved behind when we leave the site. We should take away what we bring, keep the environment clean. Second, no any notes being written in the sites. Though in the old days, Chinese workers like to leave their names on the sites, but now it is a new world, we need to behave ourselves.

In recent years, tourism has developed rapidly in China. Many people believe that tourism produce positive effects on economic growth and we should try our best to promote tourism. But what these people fail to see is that tourism may bring about a disastrous impact on our environment. As for me, I'm firmly convinced that too much tourists bring harm to the environment.
The bad impact of tourism on the environment has mainly expressed itself in various ways. One way is the proceof exploiting a new scenic spot. In order to attract tourists, a lot of artificial facilities have been built, which have certain unfavorable effects on the environment. This proceusually breaks the ecological balance of the area. In some mountainous places, trees are being cut down to build hotels for others to see and explore the beauty of the mountains. Then land slides and mud-rock flows come up. Another way the development of tourism has damaged the environment occurs when tourists go to scenic spots. Some tourists don't have the awareneto protect the environment, and ignorantly throw their garbage here and there. Some people even kill the local wildlife to eat, which badly damages the balance of the natural environment.
It is wrong to sacrifice the environment for the growth of tourism. We must keep in mind that too much tourists bring harm to the environment. We need to find a balance between satisfying the needs of tourists and reducing to a minimum the pollution they cause.

Will Tourism Bring Harm to the Environment? Tourism has developed by leaps and bounds in the past decades in the whole world. Therefore, the issue of whether the tourism will bring harm to the environment is becoming a matter of concern. As for me, I hold that the tourism does more harm than good to the world. In the first place, the more places we travel to , the more pressure will be added to the environment. Take Dunhuang as an example, the greatest scourge these days comes from the tourists who swarm here by the busload , bring destructive amounts of carbon dioxide and moisture into the caves along with their eagernefor a glimpse of ages past . Secondly, It has become fashionable for travelers to drive a private car to the place they want to . In this case ,a large number of cars are mushroomed in the road and it cause twice as much as air pollution .At this speed ,we may live in a world which is full of dirty air instead of fresh air. In sum , although tourism is playing an indispensable we`d better try to limit role in the society , I still believe that its speed according to the harm that brings to the environment.
The world we live in is becoming more and more intolerable because of environmental destruction. Bird flu and Sars are two typical examples that environmental destruction may threaten our life. Besides, forest destruction , water and air pollution result in decrease of planting land and unpleasant weather.
Serious as the problem seems, we can come up with some measures to deal with it. First of all, the authorities should adopt the policy of "sustainable development", and laws concerning environmental protection should be put into effect and enforced strictly just as our government has been doing.
What' s more, every citizen should realize the seriousneof the problem and make concerted efforts to protect our environment. In addition, planting trees helps improve and beautify the environment.
