为避免重复,条件状语从句常用助动词do(does/did)来替代上文所提到的动作。
Presentation
if引导的条件状语从句if-clause
If是连词，表示假设或条件，意思是“
如果…的话”，通常表示假设，表示将会发生和可能发生的事，或进行提醒警告。
if从句可以放在句首,
也可以放在句末。
句子结构：If+从句main
clause，主句。=主句+if+从句
。
（从句谈论可能的活动，主句谈论可能的结果）
我们用“主句用一般将来时,
if引导的从句用一般现在时”
的条件句来谈论可能发生的事件。if从句的一般现在时用于表述可能发生的动作或情况,
主句用一般将来时表述条件成立时可能产生的结果。(即主将从现)
If

if
you
want
to
have
a

If
I
am

wait
for
me.
注意：if引导的条件状语从句通常不用一般将来时。
注意：
2.如果主句是含有must，can，may
等情态动词时，根据需要从句多用一般现在时the
simple
present
tense。(即主情从现)
You
can
_____

hard.
如果你努力学习，你就能通过这次考试。

条件句不一般，几个要点记心间；
条件句，放在前，逗号要居中间；
条件句表可能，主句多用将来时；
条件句表事实，主句常用现在时。
注意：
1.if还可以用于宾语从句中，表示“是否”，相当于
whether，引导宾语从句，时态需根据语境确定。
如：I
don't
know
if
it
will
rain
tomorrow.
我不知道明天是否会下雨。
记忆口诀：
2.If条件句还有同义句：
祈使句，and
/or+将来时态的陈述句。

【考点精析】本题考查条件状语从句的基本用法。if是条件状语从句的引导词之一，意思是“如果”，当条件状语从句所连接的两个动作还未发生时，要遵循主将从现原则，即主句用将来时（一般将来时为主），从句用现在时（一般现在时为主），本题句意为“如果我有一个梦想的话，我就会一直努力认真地实现它”。可知“有梦想”和“不断努力”的动作均未发生，故应用主将从现原则，答案为C。

【答案】B
【解析】本题第一空考查if（如果）条件状语从句的基本用法。句意为“如果这周末天气好的话......”，第二空意为“没人知道是否会下雨”，if在此表示“是否”。答案为B。
Consolidation
unless引导的条件状语从句
unless是连词，表示假设或条件，意思是“意为“除非”，和if…not(如果……不……)的意思相近，且两个结构通常可以互换使用。
If
you
don’t
finish
your
homework,
I
won’t
let
you
play
outside.
如果你不完成你的作业,
我不会让你出去玩。
=
Unless
you
finish
your
homework,
I
won’t
let
you
play
outside.
除非你完成你的作业,
否则我不会让你出去玩。
注意：在unless引导的从句里，通常用现在时表示将来。
【运用】
用unless
和
if…not完成句子。
