1.用句型“be afraid that從句”表達(dá)“害怕某人做某事”的確可以,不過更簡潔的短語是：be afraid of sb/one's doing sth.
2.短語區(qū)別如下：
1) be afraid to do sth 因?yàn)楹ε露桓易瞿呈?br/>如：I'm afraid to go out alone at night.
2）be afraid of doing sth 害怕會(huì)發(fā)生某事
如：I'm afraid of being beaten by my father.
3.所以,“害怕某人做某事”應(yīng)該是使用be afraid of doing sth結(jié)構(gòu)中動(dòng)名詞短語的復(fù)合結(jié)構(gòu)即：be afraid of sb/one's doing sth.
其中的sb/one's即人稱代詞賓格/形容詞性物主代詞,如果是名詞則用其普通格或所有格形式.
如：I'am afraid of him/his getting angry.
I'm afraid of Tom/Tom's getting angry.
我害怕湯姆生氣.
