[英语语法]"all you have to do is take one " --- why not " is to take one"?
"Life offers you a thousand chances all you have to do is take one."
最近总是读到似乎的语句,就是 'is' 与另一个动词直接连着用.我看的那些书还算权威出版的---我的意思不是经常出错的那种.
但是我的文法知识告诉我.上面那句话,应该写成’ all you have to do is to take one' 才是正确的.
但底哪个对?
但是，“前面主语中出现了do 的某种形式，如do ,did to 可省略”，这个说法出自何处呢？
在网上，主要有如下两个页面，但是已经说不清谁引用谁了。内容如下。
不定式作表语时满足两种情况不定式的to可以省略
1.句中出现了do 的某种形式，如do ,did to 可省略
2.由and,or 等连接并列的不定式时，第二个（或后面）动词不定式不带to.

2.由and,or 等连接并列的不定式时，第二个（或后面）动词不定式不带to.
“The golden rule here is spread your risk.”这一句，又是属于哪种情况？

不定式作表语也可以有do 无to
也就是前面定从中紧挨is 是to do 后面作表语的不定式可以省略to
在说一遍
正常情况下,不定式做表语to不能省略.如：
The next step is to make sure that you know exactly what is required.
但有特殊情况,to可省略：
前面主语中出现了do 的某种形式,如do ,did 等,to 可省略

all you have to do is cry All you have to do is to tell yourself not to be angry. All you have to do is to listen All you have to do is do sth All they do is what they have to do,not what they like to do All you have to do is open yourself up. All I have to do is loveing you forever All you have to do is follow me.求详解. Why you do not have to go to school? do you think it is good to be famous?why or why not? One day,you have to do is one thing,to be good. all i have to do is to do sth
