2. He got his driving license last month. 一般过去时
3. If you go to New Zealand, you are going to like the place. 一般将来时
4. She told me that she would go on trip to Europe the next day. 过去将来时

8. The telephone rang no sooner than he had come into the house. 过去完成时
9. I’ve been waiting for you for the whole morning. 现在完成进行时
二．要注意的几个问题
1. 每学一种时态，要反复地、认真地去琢磨这种时态的作用及其使用的语言环境。
e.g. He speaks English .（一般现在时，说明动作发生的经常性。）
He spoke English when he was in New Zealand .（一般过去时，说明动作发生的时间。）
He is speaking English.（现在进行时，说明动作正在进行。）
He has learned English for three years since he came to the USA. （现在完成时，这里说明动作的总和。）
He has been speaking English since he came to the USA. （现在完成进行时，强调动作的连性。）
2. 在时间状语从句或条件状语从句的中，如果主句的谓语动词是一般将来时，那么从句的谓语动词就只能用一般现在时来表示将来时；如果主句的谓语动词是过去将来时，那么从句的谓语动词就只能用一般过去时来表示过去将来时。
e.g. I will not play tennis if it rains tomorrow.
I would not play tennis if it rained the next day.
3. 在使用现在完成时的句子里，不可以带有表示具体过去时间的状语，如：yesterday , last week ( month , year , etc. ) , two weeks ago , in 1999等；但常和有些副词连用，如： just , before , already , often , never , ever , not…yet , always等等。
4. 在以when提问的特殊疑问中不能用现在完成时。另外，ago不能用于现在完成时的句子里，但是可以用before 来表示"以前"的意义.
1)---When did the train leave? ---It left ten minutes ago. 2)I have read this before.
5. 如果是不表示连续性的动词用于现在完成时的句子，不可以和表示"一段时间"的状语连用。在这种情况下，应该用"It is… since…"的句式来表达。
He has joined the army for five years. （wrong）
It is five years since he joined the army. （right）
三，被动语态的几个问题
1. 要想正确地使用被动语态，就须注意哪些动词是及物的，哪些是不及物的。特别是一词多义的动词往往有两种用法。解决这一问题唯有在学习过程中多留意积累。
The accident was happened last week. (wrong)
The accident happened last week. (right)
2. 主动形式表示被动意义
1)表事物特性 v +adv. (wash, cut, sell, read, wear, write, sell, tear）
The book sells well. This knife cuts easily. Paper tears easily.
2）I was to blame for the accident.
3) 在need, require, want, be worth 后的动名词必须用主动形式。
The door needs repairing.= The door needs to be repaired.
This room needs cleaning. This book is worth reading.
四，主谓一致
1. 由or 连接两个名词或代词作主语时，谓语动词应与靠近它的主语一致。还有either … or … , neither … nor …, not only … but also … 即是就近原则。
e. g. Are you or he to drive ? Was she or you there ?
2. 由两个名词由with (together with，along with，as well as , rather than ，no less than ，but， besides，except )连接时，谓语动词应与前面的主语一致。
e. g. Nobody but John and Helen was absent. I rather than you, am responsible for the accident.
