时态使用重大的规则:(12字原则)
主过从过,主将从现,主现从任
【主将从现】 常见的有以下
三种情况:
一、When/if 引导的主句是一般将来时,从句用一般现在时。
I"ll tell her the good news when she comes back.当她回来的时候,我将把这个好消息告诉她。
If it doesn"t rain, he will come here on time.如果不下雨,他会按时来这儿的。
二、如果主句是祈使句,那么从句要用一般现在时。
Don’t laugh at me when I make a mistake.我犯错误的时候不要笑话我。
三、如果主句是含有情态动词的一般现在时,从句多用一般现在时。
You should be quiet when you are in the reading room. 在阅览室时应保持安静。
【主过从过】 常见的有以下
二种情况:
1.直接引语变成间接引语
2.宾语从句中,当主句的谓语动词为过去时态时,从句须用表示过去的某种时态。例如:
He asked when they would go to the party.他问他们什么时候将去参加聚会。 Miss Green said she had been to Beijing before.格林小姐说她以前曾经去过北京。 【主现从任】 常见的有以下
一种情况:
在宾语从句中,当主句的时态为现在的某种时态(一般现在时、现在进行时、现在完成时等)后面从句时态不受主句限制,可选用各种适合的时态。 例如:
Do you know when we"ll have a football match?你知道我们什么时候举行足球赛吗?
You know he has gone to Shanghai.你知道他已去上海了。 【特别关注】
1.当宾语从句表述的是客观事实、科学真理、现在的习惯动作以及格言等时,只能用一般现在时。例如:
The teacher told us that light travels faster than sound.老师告诉我们光速比音速要快。
2.如果主、从句表示的动作是一前一后发生的,则先前的用过去完成,在后的只能用一般过去时态。
When he got there, the train had left.当他到那儿的时候,火车已经开了。
