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

Answer 2

1。doesn't rain 主句用将来时从句用一般现在时
2。sharing look foward to doing sth 盼望做某事
3. lying spend time [ in ] doing sth 花时间做某事
4。waiting 介词after后要用 v-ing 形式

一定是正确的，望采纳
