all i have to do is to do sth
all i had to do was to write a story and present it
为什么write不改为wrote,前后时态一致?

这里主要有两个语法现象:
1.all I have to do is 的后面需要跟不定式,即to加上动词原型.
这个原型不受前面的have的时态的影响,不管是have,had,will have,had had等等,后面的只能是is加不定式；也不受这个is的时态影响,不管是is,was,will be,had been,is后面的只能是不定式.这个句子里面需要注意时态关联的是have和is需要一致,他们跟后面的不定式无关.
2.就是不定式的语法了,不定式通常是to+动词原型,而在本题的这个句型里面,更多的时候to可以省略,于是你的句子可以改写成：All I had to do was write a story and present it.google搜索的结果也表明人们更习惯于省略to.

all i have to do is to do sth All you have to do is do sth have sth to do have to do sth All you have to do is 的用法.后面是跟to do sth还是ding sth It is not necessary to do sth enjoy doing sth I like to have 《all i have to do is dream》歌词的中文翻译 all i have to do is dream的中英文 All I have to do is loveing you forever all i have to do is dream 的语法 All I have to do is dream 歌词的中文 “All I have to do is learning English.
