有几道英语题啊
一、根据题意和所给字母提示,补全句子中的单词.
1.What's your attitude tˍˍˍˍ what the kids wear to school?
二、根据题意,用所给单词的适当形式填空.
1.We must do something to pervent them from ˍˍˍˍ(pour) waste water into the rivers.
（我觉得这个应该是pouring,prevent sth. from doing sth.）
2.At last,all the people in the room couldn't help ˍˍˍˍ(laugh)
（这个can not help laugh是禁不住笑的意思,这里是不是要用原形那?）
三、请根据所给汉语提示完成下列英语句子,每空一词
1.I just ˍˍˍˍ ˍˍˍˍ(顺便来访）to see how you were getting on.
（我只知道有个顺便来访叫drop by,但是我觉得填上之后,我读着很别扭“drop by to,怎么读怎么觉着to前面放drop by不对.）
四、用所给形容词或副词的适当形式填空.
1.John spends a lotˍˍˍˍ(much)time on Chinese than before.
（是不是直接把much写上就行了?）
That's over,I don't konw how to work out these problems , please tell me,thanks a lot
