30 時(shí)間狀語從句 Track 030

(1)時(shí)間狀語從句要用一般現(xiàn)在時(shí)表示將來動(dòng)作
a. I’ll speak to him when he arrives.
不說…when he will arrive.*
b. I’ll tell him about it when he comes back.
不說…when he will come back.*
(2)when
when的意思相當(dāng)于at that time(在……時(shí)刻),從句的謂語動(dòng)詞通常是短暫性動(dòng)詞,表示瞬時(shí)的動(dòng)作。注意主句和從句的時(shí)態(tài)
例句
a. I’ll speak to him when he arrives.
b. I’ll tell him about it when he comes back .
c. When I arrived, he was talking on the phone.
我到的時(shí)候,他正在打電話。
d. When I got there, he had already left.
我到那兒的時(shí)候,他已經(jīng)走了。
e. When I got there, he was leaving the office.
我到的時(shí)候,他正準(zhǔn)備離開辦公室。
從句的謂語也可用延續(xù)性動(dòng)詞,這時(shí)從句往往用過去進(jìn)行時(shí)態(tài),表示過去某一時(shí)間正在發(fā)生的動(dòng)作。例如:
f.The doorbell rang when I was telephoning.
(3)while
while的意思相當(dāng)于during that time(在……期間),表示某一時(shí)間段內(nèi)發(fā)生的動(dòng)作。因此,從句謂語通常只用延續(xù)性動(dòng)詞。
例句
a. The phone rang while I was taking my bath.
b. The doorbell rang while we were watching TV.
c. A detective(偵探) arrested a criminal and was about to handcuff(上手銬) him when a huge gust(一陣狂風(fēng)) of wind blew off the detective’s hat.
“Shall I go and fetch it?” the criminal asked.
“Do you take me for a fool?” asked the detective. “You wait here while I go and get it!”(此句中g(shù)o and get雖然是短暫性動(dòng)詞,但兩個(gè)動(dòng)詞連用表示的是一段時(shí)間內(nèi)的活動(dòng)。)
(4)until
1) 當(dāng)主句謂語動(dòng)詞是延續(xù)性動(dòng)詞時(shí),主句通常用肯定形式。例如:
a. Wait until he comes back. (wait為延續(xù)性動(dòng)詞)
b. We’ll stay here till it stops raining. (stay為延續(xù)性動(dòng)詞)
c. Until I came back, he had been waiting for me at my home.
2)若主句謂語動(dòng)詞是短暫性動(dòng)詞,則主句要用否定形式。這就是我們常說的“not…until…(直到……才……)”結(jié)構(gòu)。
例句
a. I did not realize how special my mother was until I became an adult.
直到我長(zhǎng)大成人以后,我才懂得母親是多么不平凡。
b. Ice cream did not reach America until about the middle of the eighteenth century.
c. I didn’t go to bed until 12 o’clock last night.
我昨晚直到12點(diǎn)鐘才睡覺。
d. He didn’t leave the office until his boss came back.
直到老板回來之后他才離開辦公室。
3)我們還可以把not…until轉(zhuǎn)換成倒裝句型:
a. Not until 12 o’clock last night did I go to bed.
b. Not until his boss came back did he leave the office.
可見,當(dāng)Not until提前至句首時(shí),主句用部分倒裝。
(5)表示“一……就……”的連詞
表示“一……就……”的連詞有:as soon as, once, immediately,the moment。這些連詞后通常接短暫性動(dòng)詞,表示瞬間動(dòng)作。注意分析下列句子:
a. We will leave as soon as it stops raining.
雨一停,我們就動(dòng)身離開。
b. Once it stops raining, we will leave.
c. It began to rain as soon as I arrived home.
我剛到家,天就下起雨來。
d. It began to rain immediately I arrived home.
e. It began to rain the moment I arrived home.
(6)by the time
by the time的意思是“當(dāng)……時(shí)候”,強(qiáng)調(diào)的是“一個(gè)動(dòng)作在另外一個(gè)動(dòng)作發(fā)生時(shí)已經(jīng)完成”。因此,與by the time從句搭配的主句要用完成時(shí)態(tài)。注意下句時(shí)態(tài)搭配:
