高一英语必修3Unit 4Astronomy the science of the stars知识点总结
Unit 4 Astronomy:the science of the starsPeriod 1 Grammar points.一.语法要点主语从句:在复合句中作主句的主语的从句叫主语从句。
引导主语从句的词有连词that, whether;连接代词who, what, which;连接副词when, where, how, why等。
Eg: Which team will win the match is still unknown.主语从句放在句首,句子常显得笨重,因此一般把它放到句子后面,前面用引导词”it”来作主语。
Eg: It’s strange that he didn’t come yesterday.二.重点难点1.Nobody knew that it was going to be different from other planets going to be different from other planets going round the sun.going round the sun 为现在分词短语定语,表示一般的动作。
Eg: Men breaking the law will be punished.现在分词短语,也可表示进行的动作2. Weather life will continue on the earth for millions of years to come will depend on whether this problem can be solved.for millions of years to come 中不定式to come 作定语,与前面的名词有逻辑上的主谓关系。
Eg: She is the last person to tell lies.3.The problem was that the earth became violent because it was not clear whether the solid shape was to last or not.The problem was that …, that 引导表语从句,that 只起连接作用,无意义,但不能省略。
