Unit 3 Language in use
【Grammar 语法点拨】
现在完成时与for和since连用
现在完成时除了表示过去发生的事对现在的影响，还可以表示
，且常和for 和since 连用，for后面加
(时间点/时间段) , sicnce 后加 或一般过去时的句子。因为表示的是持续的动作或状态，所以使用的动词通常是延续性动词。如:
我们可以说，I have had a cold for two days. 我感冒两天了。(have-延续性动词)
但不可以说, I have caught a cold for two days. (×) (catch-非延续性动词)
非延续性动词想要表达延续的意义时,我们可以用相应的延续性动词或动词短语来替换部分短暂性动词或与之对应的延续性动词. 如，marry 是非延续性动词动词，那我们表示某人已经结婚一段时间了，我们可以说，
She has get/been married for 2 years. 她结婚两年了。
但不可以说，She has married for 2 years.(×)
延续性动词与非延续性动词之间的转换：
leave --- be away, borrow --- keep, buy --- have,
begin/start --- be on, die --- be dead, finish --- be over,
join --- be in+组织机构, be a member of+组织机构,
open sth --- keep sth open, fall ill --- be ill, get up---be up,
catch a cold --- have a cold, come here --- be here, go there --- be there,
become --- be, come back --- be back, fall asleep --- be asleep,
get to/ arrive/reach --- be (in), leave --- be away from,
get to know --- know, go (get) out →be out， put on→ wear；
catch a cold →have a cold等。
3. for 与 since 二者后接的词有所不同:
(1)for 后常跟一个时间段,如 for two years。
E.g. Mary have learned Chinese for three years. 玛丽学习汉语已经有三年了。
(2)since 后跟一个时间点,如since 1980;也可以接 “一段时间+ago”,如 since three years ago, since two months ago;还可接一般过去时的从句,如 since he came here。
E.g. She has been heartbroken(心碎) since her boyfriend left her.
E.g. She has been heartbroken since half a year ago.
It is + 一段时间 + since 从句.
g. It is one year since her boyfriend left her.自她的男朋友离开她已经一年了。
4.对以上表示时间段的状语进行提问用特殊疑问词how long:
How long have you play soccer on the playground
【反馈练习】用for / since 填空
