Trees provide us with a lot of useful things, such as fruits, wood, and even jobs. And they are very helpful to protect our living environment. People and animals depend on trees a lot. However, trees are getting fewer and fewer these days. People cut down a great number of trees for money and they don’t plant trees. What’s worse, some forests are losing because of wildfires. What a pity. Therefore, it is time to do something to protect trees. Firstly, we should call on people not to cut down so many trees and some laws should be carried out to stop people from cutting down trees. Secondly, we can hold some activities to plant trees on some special days, such as the Tree Planting Day. Thirdly, we should not drop any drink bottles or cigarettes in the wild, which may cause forest fires. I hope everyone can protect trees. In fact, protecting trees means protecting ourselves. 【详解】[总体分析] ①题材：本文是一篇材料作文； ②时态：时态是“一般现在时”； ③提示：考生应注意不要遗漏要点，并要适当发挥补充，注意使用正确的词汇和句型，注意行文连贯和逻辑。 [写作步骤] 第一步，表明写作意图，以“树木是人类的朋友并且很有帮助”来引出下文； 第二步，说明树木的重要性以及树木日渐减少的现状和原因； 第三步，表述保护树木的措施，可用firstly，secondly，thirdly这样的词语使得文章更连贯，并注意总结文章，强调要保护树木。 [亮点词汇] ①provide sb. with sth.给某人提供某物 ②depend on依赖 ③a great number of大量的 ④stop sb. from doing sth.阻止某人做某事 [高分句型] ①Firstly, we should call on people not to cut down so many trees and some laws should be carried out to stop people from cutting down trees.（带有情态动词的被动语态） ②Thirdly, we should not drop any drink bottles or cigarettes in the wild, which may cause forest fires.（which引导非限制性定语从句） 2. 假如你是一名志愿者，周日上午，你来到公园， 看到市政府为市民免费提供自行车服务。回校后你与同学们展开了怎样保护树木的讨论。请根据下面的提示，以“How to save trees”为题，写一篇英语短文。 要求: 呈现以下所有要点、条理清楚、语法正确、语言流畅。可以适当发挥。不少于80 词。 提示词语: instead of 代替；send 发送；both sides of every piece of paper 每张纸的两面 How to save trees ____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ 【答案】例文： How to save trees Trees are very important to us, so we should try our best to protect them well.
