1、主句是一般现在时,从句根据实际情况使用任何时态。 例句: She says (that) she works from Monday to Friday. 她说她从周一至周五上班。(从句是一般现在时) She says (that) she will leave a message on his desk. 她说她要在他桌子上留个便条。(从句是一般将来时) 2、主句是过去时态,从句须用过去时态的某种形式。 例句: He said there were no classes yesterday afternoon. 他说昨天下午没有课。 (从句是一般过去时) He said (that) he was going to take care of the baby. 他说他会去照看这个婴儿。 (从句是过去将来时) 3、当宾语从句表示的是一个客观真理或者事实时,即使主句是过去时,从句也用一般现在时态。 例句: The teacher told us(that) nothing is difficult if we put our hearts into it. 老师告诉我们世上无难事,只怕有心人。 She said(that) her father is twenty-eight years older than her. 她说她父亲比她大二十八岁。 He said that light travels much faster than sound. 他说光比声音传播得快。 注意:当主句的谓语动词是think或believe,宾语从句要表达否定时,要把从句的否定转移到主句上。 I don't think he is going to help you with your English. 我认为他不会帮你学英语的。 这句话不可以翻译成: I think he isn't going to help you with your English. 如果宾语从句有它的补语时,宾语从句用it代替,从句后置。其句型为:主语+谓语 + it +补语+宾语从句。 I think it necessary that we learn English grammar. 我认为我们学习英语语法是必要的。 好了,以上的这些还请大家务必要掌握,在日常的学习中一定要勤加练习,多加记忆,直到掌握。 |
