Rushtosummer的学习笔记(9)动词的时态
1 一般现在时every …, sometimes, at …, on Sunday,
注意:一般现在时表示客观真理,客观存在,科学事实或格言、警句,如果出现在宾语从句中,即使主句是过去时,从句谓语也要用一般现在时。
例:Columbus proved that the earth is round.
2 一般过去时yesterday, last week, an hour ago, the other day, in 1982, just now
·
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"
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。
·
注意: 用过去时表示现在,表示委婉语气。动词 want, hope, wonder, think, intend 等。如Did you want anything else?
I wondered if you could help me.
·
used to + do:"过去常常"
表示过去习惯性的动作或状态,但如今已不存在。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。
3 一般将来时
next…, tomorrow, in+时间
1)shall用于第一人称,常被will 所代替。
2)
be going to +不定式,表示将来。
3) be +不定式表将来,按计划或正式安排将发生的事。
4)
be about to +不定式,意为马上做某事。
注意:be about to 不能与 tomorrow, next week 等表示明确将来时的时间状语连用。
·
用于条件句时,be going to表将来,will表意愿
·
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。
4 一般现在时表将来
1)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。
2)倒装句,表示动作正在进行,如:Here comes the bus. = The bus is coming.
3)在时间或条件句中。When Bill comes (不是will come), ask him to wait for me.
4)在动词hope, take care that, make sure that等后。I hope they have a nice time next week.
5 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。6 现在完成时 for, since, so far, ever, never, just, yet, till/until, up to now, in past years, always, recently
·
构成: have (has) +过去分词。
·
用于现在完成时的句型
1)It is the first / second time… that… 结构中的从句部分,用现在完成时。
2)This is the… that…结构,that 从句要用现在完成时。
·
Since 用来说明动作起始时间,for用来说明动作延续时间长度。
注意:并非有for 作为时间状语的句子都用现在完成时。
·
小窍门:当现在完成时+一段时间,这一结构中,我们用下面的公式转化,很容易就能排除非延续动词在完成时中的误使。
1)
(对) Tom has studied Russian for three years.
= Tom began to study Russian three years ago, and is still studying it now.
2)
(错) Harry has got married for six years.
= Harry began to get married six years ago, and is still getting married now.
·
since的四种用法
1) since +过去一个时间点(如具体的年、月、日期、钟点、1980, last month, half past six)。
2) since +一段时间+ ago
3) since +从句
4) It is +一段时间+ since从句
7 过去完成时
before, by, until, when, after, once, as soon as
表示过去的过去,had +过去分词构成。
1) 用法
a.
在told, said, knew, heard, thought等动词后的宾语从句。
b. 状语从句,在过去不同时间发生的两个动作中,发生在先,用过去完成时;发生在后,用一般过去时。
c. 表示意向的动词,如hope, wish, expect, think, intend, mean, suppose等,用过去完成时表示"原本…,未能…"
We had hoped that you would come, but you didn't.
2)
过去完成时的时间状语before, by, until, when, after, once, as soon as。
注意:had no … when还没等…… 就……
had no sooner… than刚…… 就……
8 将来完成时
1) 构成will have done
2) 概念
a. 状态完成:表示某事继续到将来某一时为止一直有的状态。
b. 动作完成:表示将来某一时或另一个将来的动作之前,已经完成的动作或一获得的经验。
9 现在进行时

基本用法:
a. 表示现在( 指说话人说话时) 正在发生的事情。
b. 习惯进行:表示长期的或重复性的动作,说话时动作未必正在进行。
c. 表示渐变的动词有:get, grow, become, turn, run, go, begin等。
d. 与always, constantly, forever 等词连用,表示反复发生的动作或持续存在的状态,往往带有说话人的主观色彩。
