一、不定式做主语：
1、不定式做主语一般表示具体的某次动作。===动名词doing表示习惯的，经常的动作。
e.g: To finish the building in a month is difficult.
To do such things is foolish.
To see is to believe. (对等)
注: 1).不定式作主语时,谓语用单数
2).当主语较长，谓语较短时，常用it做形式主语，而将不定式放到谓语的后面。
it做形式主语，不定式放在谓语动词之后常用于下列结构中：
(1)It is/was +adj.+of sb. to do…
(2) It is +adj.+for sb.+to do…
It is easy / difficult / hard / foolish / unwise / right / wrong / unnecessary
(3) it is +a +名词+ to do...
It is a pity / a pleasure / a pleasant thing / one’s duty / an honor / a shame / a crime / no easy job… to do
It takes (sb.) some time / courage / patience …to do…
It requires courage / patience / hard work… to do…
注意: probable和possible均可作表语，但possible可以用不定式作真实主语，而probable不能用不定式作真实主语。
It is probable for him to come to the meeting.(错)
It is possible for him to come to the meeting.
It is possible / probable that he will come to the meeting.

高考英语基础差如何快速提高成绩
1、高考英语基础差坚持背单词，记住单词最有效的方法就是边背边写，每天都把之前背过的复习一遍。然后就是读英语课文，最好是跟着录音读，读课文的同时还能提高英语语速规范读音。上课的时候把老师讲的课文中的重点段落或者句子标记出来，下课背会。
2、基础差把平时做错的题都整理一下，总结一下容易犯错的地方，每次考试之前都把复习重点放在错题本上，避免高考考试的时候再犯同样的错误。
3、高中因为高考英语的题型都是固定的，平时考试的题型也都是按着高考来的，所以基础差的同学们平时可以针对题型做专项练习，高中掌握每种题型的答题方法和技巧，提高正确率。
