The environment pollution is becoming more and more serious. We can see white pollution everywhere. There has been hazy weather in many parts of China in recent years. I suggest that we should try to take a bus or an underground instead of driving by ourselves.. We should prevent factories from dumping the waste into rivers to reduce water pollution. We shouldn’t use disposable plates, bowls. We should plant more trees and grow grass to prevent it. We should also prevent people from cutting down too many trees. If we try our best, the environment will be better and better.



试题分析：本题是围绕保护环境展开叙述，首先应该说明保护环境的重要性，然后，分别叙述如何才能保护环境。最后，要发出倡议，号召大家要从小事做起为保护环境尽一份力。在写作时，本文的主语可以用第一人称，时态一般应该用一般现在时。应该尽量包括文中提示的内容，可稍加拓展。
点评：以提纲提供情景的作文。这种形式本身的要点已经很明确，重点也很突出，只要把各个提纲加以发挥，注意遣词造句的灵活性和语法规则的正确性，就不会造成审题不清而偏离主题，但要注意，文章必须覆盖所提供的各个提纲的要点。
