條件狀語從句條件狀語從句主要由if或unless引導(dǎo)：

if條件句

1)if條件句：條件句用于陳述語氣，表示假設(shè)的情況可能發(fā)生，其中

if

是“如果”的意思。e.g.Ifitrains,wewillstayathome.如果下雨我們就待在家里。Grammar2)

用法：

(1)條件狀語從句通常由連詞if引導(dǎo)，意為“如果、假如”，主句不能用be

going

to表示將來，而應(yīng)該用shall,will。e.g.If

you

leave

now,

you

will

never

regret

it.

如果你現(xiàn)在離開，你永遠(yuǎn)都不會(huì)后悔。(2)if

“如果”，引導(dǎo)條件狀語從句，主句用一般將來時(shí)，從句則用一般現(xiàn)在時(shí)。e.g.If

it

rains

tomorrow,

I

shan’t

climb

the

hills.如果明天下雨，我就不爬山了。(3)主句是祈使句或含有情態(tài)動(dòng)詞，從句也用一

般現(xiàn)在時(shí)。e.g.Please

call

me

if

he

comes

next

Sunday.如果他下周日過來請(qǐng)打電話給我。注意:

賓語從句中的if與條件狀語從句if的區(qū)

別。賓語從句中的if

“是否”相當(dāng)于

whether,引導(dǎo)賓語從句,時(shí)態(tài)需根據(jù)語境確定。如果主句用一般現(xiàn)在時(shí),從句可以根據(jù)具體情況選用時(shí)態(tài),如果主句用一般過去時(shí),從句必須用過去時(shí)的某種形式。unless條件句unless引導(dǎo)的條件句，表示強(qiáng)烈的否定。翻譯為“除非……”“非……不可”。e.g.You

will

fail

unless

you

work

harder.

你不努力就會(huì)失敗的。=Youwillfailifyoudonotworkharder.注意:unless

從句里的謂語只能是肯定式,因?yàn)楸旧韚nless表示否定。單項(xiàng)選擇。1.If
