二、语法和从句分析
1. it 作形式主语(真正主语是后面的不定式):“It is easier to find information online than in print books.” / “this makes it difficult to evaluate information”——it 是形式主语/宾语,真正主语是 to do。
2. 时间状语从句(when):“we need to be careful when we look things up on the internet” / “When we write emails, posts and comments, we can communicate with many people.”
3. 条件状语从句(if):“If we communicate in the right way, we can have a positive effect on people's lives.”
4. 定语从句(省略 that/which):“everything we read” / “the things we publish on the internet” / “people we do not know”——关系代词作宾语时可省略。
5. 动名词作主语:“Writing posts and comments is an important way to communicate.”——动名词短语作主语,谓语动词用单数(is)。
6. 比较级:“easier than”、“more interesting to read”——easier 是 easy 的比较级(去 y 加 ier),more interesting 是多音节比较级。
7. need / should / can 后接动词原形或不定式:“need to be careful”、“should be kind”、“can use / communicate”。
8. so … that / so 表结果:“there is so much content that it is difficult …”(so much + 名词 + that 从句,表“如此……以至于”)。
