1. worth 和 worthy 都是形容詞，詞義基本相同，“值得的”，但用法及搭配上卻不相同。
〖點撥〗 worth “值得的”、“值得……的”，只能作表語，但不能單獨作表語，其后必有連帶成份才能成立。如：This book is worth . (錯) This book is worth reading . (正)
The necklace was worth 100 francs at most .
What / How much is it worth ?
It is worth much .
(2) 帶及物動詞的動名詞的主動一般形式，若是不及物動詞需加適當介詞，但均表示被動意思，或者說所用動名詞或動名詞短語的邏輯賓語必須是 worth 的主語。如：
This film is worth seeing it . (錯)
This film is worth being seen . (錯)
This film is worth seeing . (正)
That picture is worth looking at . (正)
(3) 接 while 或 one\'s while 一起作表語。如：
Going / To go there is worth while .
(4) 句型：It is worth while doing / to do . sth . 此句型中，it 為形式主語代替動名詞或不定式短語 doing / to do sth . 與(2)中的動名詞不同，此時的動名詞或不定式必須是完整的非謂語動詞短語作主語。如：
It is worth while discussing / to discuss the question .
It is worth while looking at / to look at that picture .
(1) 加介詞 of 短語。of 后可接名詞(一般不接表示錢的名詞)、代詞和動名詞的被動式。如：The watch was worthy of the chain .
He is worthy of his work .
This museum is worthy of a visit .
This novel is worthy of being remembered .
This question is worthy to be discussed .
(3) 放名詞前作定語，worth 不能。如：Bethune is a worthy man .
〖點撥〗注意，漢語中說“很值得時”只能用 well worth / worthy 不能用其他副詞。如：
This report is well worth listening to .
Her behaviour is well worthy of great praise .
