正確答案是：There is no point to do. to後面要接動詞原形，doing是動名詞。

答:there is no point 後接doing,做某事沒意義，相當於there is no use doing sth,there is a waste of time doing sth 例如:

There is no point trying to persuade him;he will never join us.

There is no point reading such kind of books; They are of no value for middle school students.

表示“做某事是沒有意義的”有兩種表示， there is no point to do sth 或者是 there is no point in doing sth. 兩種表示意思相同，但所用的介詞不同，注意區分。
