初中英语语法内容：时态的呼应

　　初中英语语法，是初中英语中一个重要的板块。熟练的掌握这些语法知识，对于我们英语能力的整体提高，会有更好的帮助。那么具体的初中英语语法知识都包含了哪些呢?下面小编为大家整理了“初中英语语法内容：时态的呼应”，供大家进行参考学习。

　　在英语中，不同时间里发生的动作或存在的状态，谓语动词要用不同的形式来表示，谓语动词的这种不同形式称为动词的时态。

　　英语中有8种基本时态，其中4种现在时态，对应4种过去时态。4种现在时态是：一般现在时态;现在进行时态;一般将来时态;现在完成时态。他们对应的4种过去时态是：一般过去时态;过去进行时态;过去将来时态;过去完成时态。

　　12-9 时态的呼应

　　在含有从句的复合句中，主从句的时态要求遵循一定的规则，既保持协调，又相互照应。

　　1.主句和宾语从句的时态呼应

　　(1)在含有宾语从句的复合句中，主句是现在时态或将来时态时，宾语从句的谓语动词可用所需要的任何适当的时态。如：

　　I think Tom is ill today.我认为汤姆病了。(主句一般现在时，从句一般现在时)

　　I think Tom has gone to the doctor's.我认为汤姆已经去看医生了。(主句一般现在时，从句现在完成时)

　　I think Tom went to the doctor's yesterday.我认为汤姆昨天去看医生了。(主句一般现在时，从句一般过去时)

　　(2)当主句的谓语动词是过去时，宾语从句中的谓语动词也要用过去的某种时态。如：

　　Mr.Smith told me that he would come to our school.史密斯先生告诉我他要来我们学校。(主句一般过去时，从句过去将来时)

　　Mr.Smith told me that he didn't know the news.史密斯先生告诉我他不知道那个消息。(主句一般过去时，从句一般过去时)

　　Mr.Smith told me that he had known the news already.史密斯先生告诉我他已经知道那个消息了。(主句一般过去时，从句过去完成时)

　　注意：

　　如果从句叙述的是客观真理或不可改变的事实，虽然主句用了过去时态，但从句仍用一般现在时。如：Mr.Smith told me that children under 18 in his country cannot buy alcohol.史密斯先生告诉我在他的国家18岁以下的孩子不能买酒。

　　2.主句与状语从句的时态呼应

　　在含有时间状语从句和条件状语从句的复合句中，从句用一般现在时，主句要用一般将来时，祈使句或含有情态动词的句子。如：

　　You'll make progress if you keep working hard.如果你继续努力你就会取得进步。

　　Don't get off the bus until it has stopped.直到车停稳再下车。

　　3.主句与定语从句的时态呼应

　　在含有定语从句的复合句中，主句的时态有时也决定从句的时态。如果主句的时态是现在时态，从句可根据实际需要确定时态，如果主句用了过去时态，定语从句一般也用过去时态。如：

　　This is the person I met yesterday.这就是昨天我遇见的那个人。

　　This is the person who will give us a lecture tomorrow.这就是明天要给我们作报告的那个人。

　　This was the person who would give us a lecture the next day.这就是第二天要给我们作报告的那个人。
