定语从句的时态是如何规定的?

如题所述

定语从句的时态一般不受主句的影响,主要根据具体的语境和意义而定。

例如:

1,The professor who lectured yesterday is from Peking University.

昨天做演讲的教授来自北京大学。(从句运用一般过去时)

2,The professor who is lecturing now is from Peking University.

现在正在演讲的教授来自北京大学。(从句运用现在进行时)

3,The professor who will lecture tomorow is from Peking University.

明天要来演讲的教授来自北京大学。(从句运用一般将来时)

判断关系代词与关系副词

1,方法一: 用关系代词,还是关系副词完全取决于从句中的谓语动词。及物动词后面无宾语,就必须要 求用关系代词。例如:

(错) This is the mountain village where I visited last year.

(错) I will never forget the days when I spent in the countryside.

(对) This is the mountain village (which) I visited last year.

(对) I'll never forget the days (which) I spent in the countryside.

习惯上总把表地点或时间的名词与关系副词 where, when联系在一起。此两题错在关系词的误用上。

2,方法二: 准确判断先行词在定语从句中的成分(主、谓、宾、定、状),也能正确选择出关系代词/关系副词.先行词在从句中作主、定、宾语时,应选择关系代词;先行词在从句中作状语时,应选 择关系副词。例如:

(对)Is this the museum which you visited a few days ago?

(对)Is this the museum where the exhibition was held?
