if 引导的条件状语从句
1．概念
条件状语从句是表示主句动作发生的前提或条件的从句，即
“在……条件下某事才能发生”。通常由连词 if 引导。
2．位置
if 引导的条件状语从句可位于主句之前或之后。位于主句之前
要用逗号与主句隔开；如果放在主句之后，其前不必用逗号。
3．时态
若主句为一般将来时、祈使句，或主句含有 can、may、must、
have to 等情态动词或短语时，if 引导的条件状语从句要用一般现
在时。
if 引导的条件状语从句
e.g. If it rains tomorrow, I won’t go hiking.

= Be quick, and you won’t be late for class.
②含有介词 with 或 without 的句子
e.g. If there is no water, we can’t live. = We can’t live without water.
（2）if 除可引导条件状语从句外，还可引导宾语从句，意为“是否”。
e.g. I don’t know if he will come to Jim’s birthday party tomorrow.
