比较:Christine was an invalid all her life.(含义:她已不在人间。) Christine has been an invalid all her life.(含义:她现在还活着) lived in Kentucky for seven years.(含义:达比太太已不再住在肯塔基州。)
has lived in Kentucky for seven years.(含义:现在还住在肯塔基州,有可能指刚离去) 留意: 用过去时表示现在,表示委婉语气。
1)动词want, hope, wonder, think, intend 等。例如: Did you want anything else? 您还要些什么吗? I wondered if you could help 。 2)情态动词 could, would。例如:
Could you lend me your bike? 你的自行车,能借用一些吗? used to / be used to
2 used to + do:\"过去经常\"表示过去习惯性的动作或状态,但如今已不存在。例如: Mother used not to be so 。 Scarf used to take a 。
be used to + doing:对……已感到习惯,或\"习惯于\",to是介词,后需加名词或动名词。例如:
He is used to a vegetarian diet.
Scarf is used to taking a 。 典型例题
---- Your phone number again? I ___ quite catch it.---- It\'s 69568442.
\'t \'t \'t \'t
,但从语意上看出,在听的时候没有听懂这个动作发生在过去,因此应用过去时。
三、一般将来时
1) shall用于第一人称,常被will 所代替。will 在陈述句中用于各人称,在征求看法时常用于其次人称。例如:
Which paragraph shall I read first? 我先读哪一段呢?
Will you be at home at seven this evening? 今晚七点回家好吗? 2) be going to +不定式,表示将来。
,即将做某事。例如:What are you going to do tomorrow? 明天准备作什么呢?
,支配要发生的事。例如:The play is going to be produced next month。这出戏下月开播。
。例如:Look at the dark clouds, there is going to be a ,快要下雨了。
3) be +不定式表将来,按安排或正式支配将发生的事。例如:
3 We are to discu the report next 。 4) be about to +不定式,意为立刻做某事。例如: He is about t
