用所给动词的适当形式填空 1. I will go with you if it ____ (not rain) tomorrow

Question

2. He is looking forward to ____ (share) his joy with his friends 3. My younger brother spent much time _____ (lie) in bed last sunday 4 Harry's mother was ill after ____ (wait）for him in the rain for a long time

Answer 1

1.
if
引导的从句一般有三种句型，主将从现(主句是将来时，从句用一般现在时）主现从现（主句是一般现在时。从句用一般现在时），主过从过（主句是一般过去时，从句用一般过去时）。前面表示主句，后面表示从句。
根据这个规则，第一题主句是一般将来时，从句用一般现在时即可。所以填doesn't
rain
2.look
forward
to
后跟-ing
形式，这个to
是介词
所以答案是sharing
3.spend
time/
money
(in)
doing
sth
或者spend
time
/money
on
sth.花时间/钱做某事
所以填
lying
4.after
是介词，介词后的动词用-ing
形式
所以填waiting
