状语从句易混易错:
一.1.在if引导的条件状语从句中,表示“如果”, 时态:主将从现
如果明天不下雨,我们就去公园.If it _______tomorrow, we'll go to the park.
2.if表示“是否”时,if或whether引导的是宾语从句(当从句中含有or not时,
常用whether),宾语从句的时态由句意决定。
我不知道他明天是否会来. I don't know if he ______________tomorrow.
二.“so…that…”可以与“too…to…”或“…enough to…”句型相互转换
1.他太老了,不能工作。
He is_____old______ he can’t work.
=He is _____old______work.
=He is not young ________ ___work.
三.主将从现原则
1)if,unless 等词引导的条件状语从句中.(主将从现)
2)when,till/until,as soon as,before,after引导时间状语从句(主将从现)
so that
too to
enough to
doesn’t rain
will come
主 be+so+形容词+that+从句
=主 be+too 形容词 to+动原。
=主be not 形容词 enough to do
