Welcme t + 地名欢迎到某地
介词,“给;为了”表目的
Listen and read.
Amy: And check ut these sft tys and bard games fr yunger kids. I’ve had them since I was a child. There’s als a sweater and a dress.Linda: Perfect! We always need tys and clthes.Amy: One last thing is a bread maker. My mm’s had it fr a lng time but it still wrks.Linda: Thanks s much!
Because I've had it since I was a baby. I have had this magazine fr a cuple f mnths.
a cuple f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 cuple f men get ut.
瞧!门口有两三个男孩正在等你。
Lk! There are a cuple f bys waiting fr yu at the dr.
The stries inside may be a bit ld, 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 f +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 fr me.2) 我们仍有点儿面包。 We still have ____________ bread.
a bit f/a little
a bit/a little/a little bit
And check ut these sft tys and bard games fr yunger kids.
check用作及物动词, 意为“检查, 审查”; check ut意为“察看,观察”。【拓展】①check ut 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 wrker checked ut his machine just nw.
你最好现在就去宾馆登记以便住个好房间。
Yu'd better g t the htel nw t check in t get a gd rm.
海德夫人今天上午结账走了。

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fr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+fr+一段时间 例:我好久没有见到她了。 I haven’t seen her fr a lng 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 wrked 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 abut 5000 English wrds since he went t cllege.
时间状语1. fr +一段时间 e.g. fr 8 years 2. since +过去的时间点 e.g. since 1999\ last spring 3. since + 一段时间+ ag e.g. since 23 years ag4. since + 从句(一般过去时态)e.g. Since I was a child
He has wrked here fr ver twenty years.He has learned abut 5,000 English wrds since he went t cllege.She’s been at this schl since five years ag.
【拓展延伸】含 fr 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 ag.= I’ve lived here fr 13 years.= It has been 13 years since I began t live here.
思考:与hw lng, fr 或者since搭配使用在现在完成时中的动词有什么共同特点?
Hw lng has Mary left? Hw lng has Mary been away?B. Hw lng has he brrwed the bk? Hw lng has he kept the bk?C. Maria has cme back since Mnday. Maria has been back since Mnday.D. Tny has bught the cmputer fr tw years. Tny has had the cmputer fr tw years.
“在现在完成时中,与“fr + 时间段”“since + 过去的时间点或从句”或“since +时间段+ag”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, wrk, stand, lie, walk, sleep, keep, wait, watch, sing, read, stay, live …
延续性动可以与fr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 knwn her since then.
(自从那时起我就认识她了,一直都认识,knw是延续性动词)
Eg: He has lived here fr 6 years
非延线性动词不能与fr和since引导的时间状语连用。
He has died fr tw years. (X)
He has been dead fr tw years. (√)
I have bught the bike fr 2 mnths. (X)
I have had/wned the bike fr 2 mnths. (√)
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: pen, clse, begin, finish, cme, g, mve, brrw, lend, buy, die …
在现在完成时的句子中,若含有fr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)g there (去哪里)cme back (回来)cme here (来这里)
①将非延续性动词转化为“be+形容词或副词”
be nbe therebe backbe here
penclsediemarryfinish g t bed leave
return get ut fall asleep lse fall ill get (arrive, reach) jin (becme)
be in / be a member f
②有的非延续性动词可以转化为意思相同的延续性动词:
brrw → keep(借) becme → be (成为)receive → have (收到) g t sleep → sleep (睡觉)
(穿) put n(认识) get t knw(买) buy(感冒) catch a cld
wear / be n
have a cld
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。
