请给我正确答案并且告诉我为什么是写这个答案好吗! 谢谢谢谢谢谢谢谢！！！！！！！

一.用所给词的适当形式填空。
1.Could you please tell me when __to start__ off tomorrow? 带有疑问词的不定式，作动词tell的宾语。
2.Let's __not be__ later for class.动词Let后要接不带to的动词不定式。
3.We can __easily__ become unhappy.修饰谓语动词，要用副词。
4.We will have the school sports meeting unless it __rains__.表示将来的时间、原因、条件等状语从句，用一般现在时态。

二.单项选择。
1.I like this dress,and it __B__.
A.feel soft B.feels soft c.feels softly D.is felt soft
feel作‘摸上去的感觉’讲，是系动词。所以，要接形容词。
2.There is nothing for us __ D__.
A.worry about B.worrying C.to worry D.to worry about
首先是一个句子结构for sb. to do sth.。其次，worry作为‘担心、忧虑’讲时，要与介词about连用。意思是‘所担心、忧虑’的事。
3.Smoe children are arguing about what TV programmes __C____.
A.watching B.for watching C.to watch D.will watch
前面提到过。带有疑问词时，要用动词不定式。
三.照中文意思将句子补充完整。
1.我们将竭尽全力地去帮助那些正在遭受大地震磨难的四川人民。
We shall __do/try our best__ to help the people in Sichuan who _are suffering from__ the big earthquake.
