由連詞if引導(dǎo)的賓語從句和條件狀語從句
1.if引導(dǎo)的賓語從句
I don't know if he will come tomorrow.=I don’t know whether he will come tomorrow.
賓語從句中，當(dāng)從句的成分完整、意思缺少“是否”之意時(shí)，連詞可用if;可以和whether互換。
2.if引導(dǎo)的狀語從句
If he comes tomorrow,we will play basketball.=We will play basketball if he comes tomorrow.
if意為“如果”，引導(dǎo)條件狀語從句時(shí)，既可放在主句前面，也可放在主句后面。若if條件句放在句首，從句后面常加逗號與主句隔開。
