最后一样东西
(持续)很长一段时间
Because I've had it since I was a baby. I have had this magazine for a couple of months.
a couple of有两种意思：
1. 表示具体的数量“两个” ；
2. 表示数量不定的“少数几个”，作这种虚指的用法时，具体意思往往视上下文和具体的语境而决定。
例句：我看见有两个人出去了。
I saw a couple of men get out.
瞧！门口有两三个男孩正在等你。
Look! There are a couple of boys waiting for you at the door.
Language points
The stories inside may be a bit old, but they’re still interesting.
a bit意为“一点儿, 稍微”, 修饰形容词或副词, 相当于a little;
a bit of +不可数名词, a little直接加不可数名词。
【链接】a little bit 也意为“有点儿”，可用来修饰形容词或副词。
【运用】完成句子，每空词数不限。
1) 对我来说，这个包有点儿贵。
This bag is ____________________ expensive for me.
2) 我们仍有点儿面包。
We still have ____________ bread.
a bit of/a little
a bit/a little/a little bit
And check out these soft toys and board games for younger kids.
check用作及物动词, 意为“检查, 审查”;
check out意为“察看，观察”。
【拓展】①check out 可意为“付账后离开”check in指“登记；报到”
②check还可用作名词，意为“支票, 账单”。
例句：这个工人刚察看了他的机器。
The worker checked out his machine just now.
你最好现在就去宾馆登记以便住个好房间。
You'd better go to the hotel now to check in to get a good room.

现在完成时表示动作或状态从过去某时开始，一直延续至今，还可能继续下去。这种用法称为“未完成用法”。此时常与for或since引导的时间状语(从句)连用。
现在完成时的“未完成用法”
“未完成”的句式：
（1）现在完成时+for+一段时间
例：我好久没有见到她了。
I haven’t seen her for a long time.
（2）现在完成时+since+表示过去的时间点
例：自1984年以来，史密斯先生就在这里工作。
Mr. Smith has worked here since 1984.
（3）现在完成时+since+从句
例：自上大学以来他学了大约5000个英语单词。
He has learned about 5000 English words since
he went to college.
时间状语
1. for +一段时间 e.g. for 8 years
2. since +过去的时间点 e.g. since 1999\ last spring
3. since + 一段时间+ ago e.g. since 23 years ago
4. since + 从句（一般过去时态）e.g. Since I was a child
He has worked here for over twenty years.
He has learned about 5,000 English words since he went to college.
She’s been at this school since five years ago.
【拓展延伸】含 for 和含 since 的现在完成时的句子有时可互相转换。
我从13年前开始就住在这里。
I’ve lived here since 13 years ago.
= I’ve lived here for 13 years.
= It has been 13 years since I began to live here.
思考:与how long, for 或者since搭配使用在现在完成时中的动词有什么共同特点？
How long has Mary left
How long has Mary been away
B. How long has he borrowed the book
How long has he kept the book
C. Maria has come back since Monday.
Maria has been back since Monday.
D. Tony has bought the computer for two years.
Tony has had the computer for two years.

“在现在完成时中，与“for + 时间段”
“since + 过去的时间点或从句”或
“since ＋时间段＋ago”连用的动词
必须为延续性动词。
动词按其动作发生的方式，发生过程的长短可分为延续性动词与非延续性动词。
延续性动词与非延续性动词
1)延续性动词:表示能够延续的动作,也可以表示经验与经历。
Eg: learn, work, stand, lie, walk, sleep, keep, wait, watch, sing, read, stay, live …
延续性动可以与for和 since引导的时间状语连用:
(他在这儿住了六年了,一直住在这儿,live是延续性动词，并且很有可能继续居住)
I have known her since then.
(自从那时起我就认识她了,一直都
认识,know是延续性动词)
Eg: He has lived here for 6 years
非延线性动词不能与for和since引导的时间状语连用。
He has died for two years. (X)
He has been dead for two years. (√)
I have bought the bike for 2 months. (X)
I have had/owned the bike for 2 months. (√)
2)非延续性动词:也称终止性动词或瞬间动词,表示不能延续的动作,这种动作发生后立即结束。
Eg: open, close, begin, finish, come, go, move, borrow, lend, buy, die …
在现在完成时的句子中，若含有for或since引导的时间状语，则句中谓语一定要用延续性动词。非延续性动词转换为延续性动词的方法有：
begin (start) (开始)
go there (去哪里)
come back (回来)
come here (来这里)
①将非延续性动词转化为“be+形容词或副词”
be on
be there
be back
be here
open
close
die
marry
finish
go to bed
leave
be open
be closed
be dead
be married
be over
be in
be away
return
get out
fall asleep
lose
fall ill
get (arrive, reach)
join (become)
be back
be out
be asleep
be lost
be ill
be in / at
be in / be a member of
②有的非延续性动词可以转化为意思相同的延续性动词：
borrow → keep(借) become → be (成为)
receive → have (收到) go to sleep → sleep (睡觉)
(穿) put on
(认识) get to know
(买) buy
(感冒) catch a cold
wear / be on
know
have (own)
have a cold
巧记瞬间性动词的转换：
开始离去借来还， 出生入死买到家，
穿衣入睡要感冒， 开开关关变结束。
1 begin开始 be on 6 return还 be back
2 leave离开 be away from 7 join加入 be in
3 go去 be off 8 die死 be dead
4 borrow借 keep 9 buy买 have
5 come来 be here 10 arrive到 be here
10 reach到 be here 11 put on穿 wear
12 fall asleep 入睡 be asleep 13 catch a cold 感冒 have a cold
14 open be open 15 close关 be closed
16 become变 be 17 end/finish结束 be over
巧记瞬间性动词的转换：
开始离去借来还， 出生入死买到家，
穿衣入睡要感冒， 开开关关变结束。
