3.动宾关系：在确认动词性质后，要注意审查其后面的宾语。要特别注意宾语应该用动词不定式还是应该用动名词;宾语补足语是应该带to还是不应该带to;动词后带的动名词或动词不定式的意义基本相同还是意义不同。如：

答案C

A.to have kept you waiting
B.keep you waiting
C.to keep you wait
D.keeping you wait
答案A
时态的一致：某些从句特别是宾语从句的谓语动词的时态，常受主句谓语动词的时态的影响，这种现象称为时态的呼应或时态的一致。因而在分析复合句时要注意主句和从句的时态的一致性。
主句的谓语动词是现在或将来时态时，从句的谓语动词可以用任何需要的时态。
It is said that a new hospital is going to be put up there next year.(现在时后接将来时)
Do you know 他昨天为什么没有来?
A.why he did not come yesterday
B.why he not come yesterday
C。why didn't he come yesterday
D.why did he not come yesterday
现在时后接过去时。答案A
I'll write to him when I arrive there.(主句将来时，从句现在时。)
主句的时态是过去时，从句的谓语动词一般也用过去时。
①从句的动作与主句的动作同时发生时，从句谓语动词用一般过去时或过去进行时。
He told me that his uncle...(fly)to Britain the next month.
(答案would fly)
She told me that her daughter was doing her homework.
②从句谓语动词的动作先于主句谓语动词的动作，从句用过去完成时，如：
She said she had seen the film before.
She said she had finished the work an hour before.
③从句的谓语动词的动作发生在主句谓语动词的动作之后，从句谓语动词用过去将来时。如：
She said she would come again.
He told me he would join the army the next year.
但是如果从句有表示过去的具体时间状语，谓语动词发生的动作虽在主句的谓语动词的动作之前，仍用一般过去时。如：
Johntold us hismotherdiedin 1967.
如果从句表示的是不受时间限制的真理或事实，即使主句的谓语动词是过去时态，从句仍用一般现在时。如：
The teacher told the students water boils at 100C.
She said twice two is four.
