⑥，表示“做某事值得”時，用 worthwhile 表達， 可用句式如下：
It is worthwhile + to do sth.
It is worthwhile + doing sth.
It is worthwhile + for one to do sth
It is worthwhile + one's doing sth.
It is worth one's while to do sh.
It is worth one's while doing sth.
worthwhile 用於表示“做某事值得”，句子主語是“做某事”，即用動詞不定式
或動名詞短語作主語worthwhile 作句子表語，即“做某事是值得的”。
例如“再討論這個問題是值得的”，應該說：
To discuss the problem again is worthwhile.
Discussing the problem again is worthwhile.
但習慣上常用形式主語 it 位於句首，將作主語的動詞不定式或動名詞短語後移。
It is worthwhile to discuss the problem again.
It is worthwhile discussing the problem again.
因此產生句式：
It is worthwhile + to do sth.
It is worthwhile + doing sth. （多見用此動名詞作主語）
例句：
In my opinion， it's worthwhile having a try at it.在我看來，這事值得試一試。
