They expect the amount of work will be too much, so they have decided to decrease it.
They expected the amount of work would be too much, so they have decided to decrease it.
请问老师，以上句子的动词时态是不是正确？
与，在同一句话中，当需要运用动词时态混用时，应该注意什么问题？
1) They expect the amount of work will be too much, so they have decided to decrease it. （正）
2) They expected the amount of work would be too much, so they have decided to decrease it. （误）
3) Theyexpectedthe amount of workwould betoo much, so theydecidedto decrease it. （正）
4) Theyexpectedthe amount of workwill betoo much, so theydecideto decrease it. （误）
【注意】时态直接影响句意，影响分句之间的逻辑关系，时态错了，两个事件之间的逻辑关系就讲不通。所以，时态要做到呼应和一致！
对新手而言，需要学会的8种基本时态：
（目前时间范畴） （过去时间范畴）
【通常目前时】 【通常过去时】
【目前进行时】 【过去进行时】
【目前完成时】 【过去完成时】
【通常以后时】 【过去以后时】
1. 关于时态的时间范畴问题
是目前时间范畴的时态：通常目前时，目前进行时，目前完成时，通常以后时。
这4种时态表达的定义与目前时间有关。
是过去时间范畴的时态：通常过去时，过去进行时，过去完成时，过去以后时。
这4种时态表达的定义与过去时间有关。
2. 关于时态的呼应：
原则上讲，若是“并列句”，两个并列分句在时态上要获得一致：主句是目前时间范畴的时态，从句也如果目前时间范畴的时态。主句是过去时间范畴的时态，从句也如果过去时间范畴的时态。
例句就像你上面的两个正确例句:
They expect the amount of work will be too much, so they have decided to decrease it. （正）
Theyexpectedthe amount of workwould betoo much, so theydecidedto decrease it. （正）
原则上讲，若是“主句 + 状语从句”，主句和状语从句在时态上也要获得一致：主句是目前时间范畴的时态，从句也如果目前时间范畴的时态。主句是过去时间范畴的时态，从句也如果过去时间范畴的时态。
例句：
If you study hard, you will make progress.
Tom saw a girl come to him when he was sitting there. 汤姆正坐在那儿时，看见一个女生向他走来。
在含有名词性从句的复合句中，假如主句谓语动词是过去时间范畴的时态，那样从句的时态也要用过去时间的时态。比如：
He said he understood it. 他说他懂了。
She wasn’t sure whether you were watching TV. 她不敢一定你是不是在看电视。
He told me he had graduated from middle school two years before. 他告诉我他两年前就中学毕业了。
The boy said he would do anything for his own country. 孩子说他为我们的祖国愿做任何事。
在含有名词性从句的复合句中，当主句的谓语动词是目前时间范畴的时态，从句的时态可以参考状况，不受限制。比如：
I think I was very lucky to get that job. 我想我非常幸运得到这件工作。
We wonder who built that old bridge. 大家不了解是哪个建造的那座古桥。
I remember that she was crying when I got home. 我记得当我回家时她正在哭。
You will notice that this word has several meanings. 你会注意到那个单词有几种意义。
I have known that she will regret for her mistake. 我已经了解她将为她的错误而后悔。
（4）在含有定语从句的复合句中，“时态呼应”规则，与含有名词性从句的复合句相同。
This is the house which was built by my grandfather.
This is the house which will be completed next month.
This is the house which is thought the best in the village.
【8种时态用于同一篇短文】（请找出）
I got a letter from my sister yesterday. She lives in a foreign country. In her letter, she said that she would come to China next year. If she comes, she will get a surprise. We are living in a beautiful new house now. The building work on it had begun before my sister left. The house was completed almost a year ago. It has been the only modern house in this area ever since.
I still remember that so many of us were living in a very small house when my sister left home. But now the new house has many large rooms and there is a lovely garden. Though it looks strange to some people, it is really very comfortable.
