條件狀語從句條件狀語從句主要由if或unless引導：

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，意為“如果、假如”，主句不能用be

going

to表示將來，而應該用shall,will。e.g.If

you

leave

now,

you

will

never

regret

it.

如果你現(xiàn)在離開，你永遠都不會后悔。(2)if

“如果”，引導條件狀語從句，主句用一般將來時，從句則用一般現(xiàn)在時。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)動詞，從句也用一

般現(xiàn)在時。e.g.Please

call

me

if

he

comes

next

Sunday.如果他下周日過來請打電話給我。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”相當于

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

will

fail

unless

you

work

harder.

你不努力就會失敗的。=Youwillfailifyoudonotworkharder.注意:unless

從句里的謂語只能是肯定式,因為本身unless表示否定。單項選擇。1.If
