名词性从句作介词的宾语：
*介词在英语中称作preposition,简写为prep.
a) 此时仅能用whether从句或疑问词引导的名词性从句作宾语。that从句不可作介词的宾语。
I am worried about whether he can do it. 我很担心他是否能做这件事。
I’m curious about how he'll cope with the problem. 我很好奇他将如何应付这问题。 /kop/ n. 长袍 vi. 处理；对付；竞争
I am sure of that the team has won the game. (WRONG)
b) 遇有介词，且非要使用that从句时，其补救方法如下：
（1）介词+the fact+that从句
如此，就可用the fact作介词的宾语，而that从句就成了the fact的同位语。
I am sure of the fact that the team has won the game. 我确定这一队赢了这场比赛。
I am worried about the fact that he doesn't study. 我担心他不学习。
（2） 保留介词，不加the fact,但介词之后的that 从句要做下列变化：
第一步：去除that
第二步：that后的主语变为所有格
第三步：动词变为动名词
I am worried about that he plays around all day.
---I am worried about his playing around all day. 我为他整天游手好闲而担心。
注意： （a）that从句若有助动词do、does、did时，予以去掉即可。
I am worried about that he doesn't study.
---I am worried about his not studying.
(b）that从句若有助动词will或would时，予以去掉即可。
I am sure of that the team will win the game.
---I am sure of the team's winning the game.
(c) 从句若有下列助动词时，做下列变化：
may--- be likely to
can --- be able to
再将be动词变为动名词being.
I am happy about that he may come . (wrong)
---I am happy about his being likely to come. 我很高兴他很可能回来。
I am sure of that he can do it. （wrong)
---I am sure of his being able to do it. 我确定他能做这件事。
3. be + adj. （adjective）+ that 从句
也就是去掉介词，将that从句放在形容词后面，作其宾语。
3.1 I am worried about that he plays around all day.
---I am worried that he plays around all day.
I am sure of that the team has won the game.
---I am sure that the team has won the game.
注意：
（a) 以上三种用法中，（1）（3）最为普遍，但（2）是考试常考的一种句型。
（b）有时介词后亦可直接接that从句，而不需the fact,形成惯用语，应牢记。
