首先,你得多看一看关于完成时的例句,清楚它在什么情况下才能使用,不要见了过去就用完成,风牛马不相及啊
1、---Have you known Dr.jackson for a long time?\
----Yes,since she_____the Chinese Society
为什么填joined而不是has joined
since从句中只能用一般过去式,主句中才加has
2、---If the wather had been better,we could have had apicnic.But it___all day
为什么填rained而不是has rained
这跟完成时没有关系,你要清楚完成时的意义,
3、---Officials say that few
patients___with the virus owing to the effective prevention
为什么填are infected而不是have been infected
答案同二,只是一般现在的状态,强调被感染的原因,跟完成时没关系
4、---Teenagers___their health because they play computer ganmes too much.
为什么填are damaging 而不是damaged
play用的就是一般现在式,要统一,为了说明一种一直持续进行的状态
5、---By the time he realizes he___into a trap.it"ll be too late for him to do anything about it.
为什么填has walked而不是walks
他已经跳进一个圈套,注意“已经”,现在已完成,但并不是一旦表示现在完成的意义就用完成时,要看作者的意思,以及是否对现在造成影响
6、---The flowers were so lovely that they___in no time .
为什么填were sold 而不是had been sold
so..that..从句中一般是不用完成时的,that后面肯定不用完成时,多培养培养语感吧
7、---Did you tidy your room?
---No ,I was going to tidy my room but I___vistors
为什么填had而不是have had
但我有客人,没有完成意义
8、They___two free tickets to Canada,otherwise they'd never have been able to afford to go.
为什么填got而不是had got
不要看见过去时就用完成式,这个完全不靠谱
9、When I called you this morning,nobody answered the phone.Where___?
为什么填were you而不是did you go
也可以填did you go,跟were you是同一含义,你去哪了

1. since 后面用过去时，不用现在完成时。
2. 陈述一个事实
3. 为什么？
4. 和后面的时态要保持一致
5. 要体现 walk 在先，realize 在后
6. 陈述一个事实
7. 陈述一个事实
8. 陈述一个事实
9. 为什么？ 我认为两者皆可

1、---Have you known Dr.jackson for a long time?\
----Yes,since she_____the Chinese Society
为什么填joined而不是has joined
since加过去时
2、---If the wather had been better,we could have had api...
