全部题目要带上讲解！！！！！ 【急】！求速度和正确！ 有追加分！

Answer 1

1 A（现在分词作状语，因为句中已有谓语动词found)
2 D(cleaned是实义动词且是一般过去时，故用助动词代替）
3 B（固定用法：decide to do sth 决定做某事）
4 wasn't ( water是不可数名词 ,再根据bought 可知用一般过去时）

Answer 2

A find sb doing ,发现某人正在做某事
D did,因为是过去发生的，
B decide to do sth,固定的，decide 后接动词不定式
was not

Answer 3

1. A 。首先，Who cleaned the room? 是过去式。所以只能选A 或D. 而A 比D 适合。
2. B。 decide 和 go 是动词，两动词间要加介词。所以，A. B. C. D 中B 最为适合。
3. wasn't; 因为be 动词为 is, are, was, were. bought 为过去式。所以填wasn't.
