英语1.The first thing you must do is ___________the teachers before class为什么要填动词不定式而不能用动名词?2.一个句子在开头划线,如何选择是填动名词还是动词不定式?请举个例子
1.is后面表目的 根据句意判断
2.开头是动词不定式大多出现在某件事未发生的情况下,而即将要去做的.
开头是动名词大多是形容做某件事的感受或利弊等
eg.(1)To pass the test,I have to work hard.
(2) Watching the film is an enjoyable experience.

第一题:从更显之后的成分做宾语,而主语才能to do&-ing通吃的,所以请楼主在日常应用英语的时候注意用法!
第二题:参见上一题。

The first thing to do 第一件要做的事
做主语用ing,如:Rding is a good thing
为了..,用to do ,如:TO be a good student,I must study hard

1.The first thing you must do相当于主语名词 it is to do sth.是个固定结构
2.在开头的不定式和动名词都可以①表示目的用不定式 ②表示一个名词用动名词

首先我得承认我的英语也不好。
但是这里应该用不定式。如;The purpose of new technologies is to make life easier ,not to make it more difficult.这里不定式的用法是作表语。通常如果有俩个不定式的话,后面的不定式符号to 是可以省略的(如果是用来强调,对照,比较时则一帮不省略)。
如果在一个句子开头划线...

首先我得承认我的英语也不好。

如果在一个句子开头划线的话,就要看划线部分是做什么成分,用来干什么的。
如:To have my homework finished on time,i sacrificed my weekend.
在这里我就用了不定式,应为不定式放句首的时候,往往有表目的的作用“为了...."这里意思是”为了按时完成作业,我牺牲了我的周末休息时间:
Having a lot of friends is really a happy thing.这里用动名词放句首是因为动名词做主语。
对不起,由于英语这东西,凭空想象对我来讲很难,我要看到实际的题目才能选好答案,才能说是为什么。但愿对你有所帮助吧,good luck!
