0910AW SPECTACULAR 之【SU & SY SO】第九期——动词的时态
真理或不变的事实,则永远用现在时
宾语从句中的助动词ought, need, must, dare 时态是不变的。
He thought that I need not tell you the truth.
句型:
It is time for sb. to do sth"到……时间了""该……了"
It is time sb. did sth. "时间已迟了""早该……了"
It is time for you to go to bed.你该睡觉了。
It is time you went to bed.你早该睡觉了。
would (had) rather sb. did sth.表示'宁愿某人做某事'
wish, wonder, think, hope 等用过去时,作试探性的询问、请求、建议等。
I thought you might have some. 我以为你想要一些。
一般过去时表示的动作或状态都已成为过去,现已不复存在。
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)
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。(我对于used to + do过去常常记得比较清楚,而这个就很少用了)
He is used to a vegetarian diet.
Scarf is used to taking a walk.(现在习惯于散步)
be going to / will
用于条件句时, be going to表将来
will表意愿
If you are going to make a journey, you'd better get ready for it as soon as possible.

be to和be going to
be to 表示客观安排或受人指示而做某事。
be going to 表示主观的打算或计划。
I am to play football tomorrow afternoon.(客观安排)
I'm going to play football tomorrow afternoon. (主观安排)
下列动词:come, go, arrive, leave, start, begin, return的一般现在时表将来。这主要用来表示在时间上已确定或安排好的事情。
When does the bus star? It stars in ten minutes.
在动词hope, take care that, make sure that等后般现在时表将来。
Make sure that the windows are closed before you leave the room
(觉得以上两条对口语比较有用)
现在进行时表示将来
意为:"意图"、"打算"、"安排"、常用于人。常用词为 come, go, start, arrive, leave, stay等 ,如 I'm leaving tomorrow
过去时常与具体的时间状语连用,而现在完成时通常与模糊的时间状语连用,或无时间状语。

现在完成时可表示持续到现在的动作或状态,动词一般是延续性的,如live, teach, learn, work, study, know.
过去时常用的非持续性动词有come, go, leave, start, die, finish, become, get married等。
用于现在完成时的句型
