worth, worthy, worthwhile 這三個詞均可表示“值得的”，由于它們詞形相近，意義相似，所以許多朋友經常將其用混。小編今天花點力氣來個一鍋燴，讓大家美美噠享受大餐。

一、從句法功能上看

worth 通常只用作表語，具有介詞性質的表語形容詞，通常用在動詞 to be 之后，其后應接名詞、代詞（賓格）、數詞或主動形式的動名詞。不用于名詞前作定語；

This painting is probably worth thousands of pounds.

這幅畫可能價值數千英鎊。

This book is definitely worth reading.

這本書確實值得一讀。

It was a difficult journey, but it was worth it.

這次旅行很艱苦，但很值得。

worthy 和 worthwhile 可用作表語和定語。如：

It isn't worth the trouble. 不值得費那個事。

He is a worthy gentleman. 他是位值得尊敬的紳士。

（worthy作定語是表示“有價值的，值得尊敬的、有出息的，有意義的”）

His behavior is worthy of great praise. 他的行為值得高度贊揚。

They achieved a very worthwhile result. 他們取得了很有價值的成果。

We had a long wait, but it was worthwhile because we got the tickets. 我們等了很久，但還算值得，因為我們把票買到了。

worthwhile可作表語或定語，指某事物是值得的，或某事是值得花時間、金錢、精力做的，后接動詞不定式和動名詞均可。

We felt that the discussion had been very worthwhile.

我們感到這次討論很值得。

This is a worthwhile career.

這是一項值得為之奮斗的事業。

繼續這個項目很不值得。

有時，worthwhile可分拆開來，中間插入所需要的物主代詞。

This film is worth our while to see again.

這部影片值得我們再看一遍。

worthy adj. 值得的，值得尊敬的

作定語時，主要用于修飾人或諸如事業、生活等抽象名詞；作表語時，常后接被動語態的動詞不定式，或介詞 of 加名詞或被動語態的動名詞。

a worthy champion/opponent/winner

值得尊敬的冠軍/對手/獲勝者

a worthy aim/cause/life

崇高的目標/高尚的事業/有價值的生活

That's a worthy task.

那是一項很有價值的工作。

The museum is worthy to be visited/of a visit/of being visited.

這個博物館值得參觀。

Local councillors thought that the program was worthy of support.

當地政務委員們認為該規劃值得支持。

二、從所使用的修飾語來看

worth 習慣上不用 very 修飾(要表示類似意思可用 well)，而 worthy 和 worthwhile 則可以用副詞very修飾。如：

That is very worthy of our attention. 那件事很值得我們注意。

Nursing is a very worthwhile career. 護理工作是很值得干的職業。

但習慣上不說：The work is very worth doing. (very 應改為 well)

This restaurant is well worth a visit

這家飯店非常值得光顧一番。

三、從搭配習慣來看

1. 有關 be worth 的搭配習慣

(1) be worth后可直接跟名詞、代詞或動名詞。如：

These books might be worth ￡ 80 or ￡ 90or more to a collector*這些書對收藏家而言可能值八九十英鎊或更多。

《柯林斯高階英漢雙解學習詞典》

The picture is worth $ 500. 這幅畫值 500 美元。

He's worth ￡10 million.

他擁有1 000萬英鎊的財產。

注意：物、人作主語時，這個句型的含義是不一樣的。

How much [ What] is this worth?

這值多少錢？

The clock is hardly worth repairing. 這臺鐘簡直不值得修理。

This novel is worth reading.

這部小說值得一讀。

What is worth doing is worth doing well. 值得干的事就得干好。

注意：其后可接動名詞，不能接不定式，且接動名詞時，總是用主動形式表示被動意義。

(2) 在現代英語中，在be worth前使用形式主語it被認為是合習慣的。如：

It isn't worth repairing the car. 這輛汽車不值得修了。

Is it worth visiting the city? 這個城市值得去看嗎?

但是，若不用形式主語it而直接用動名詞作主語則是錯誤的，如：

誤：Repairing the car is worth.

It is worth pausing to consider these statements from Mr Davies.

戴維斯先生的這番話值得大家停下來思考一下。

(3) 在be worth doing 結構中，除非句首用了形式主語it，否則句子主語總應是其動名詞的邏輯賓語；若其中的動詞不及物，應考慮加上適當的介詞。如：

Nothing he said was worth listening to. 他說的話沒有一句值得聽。

She's not worth getting angry with. 犯不上跟她生氣。

This idea is well worth considering.

這個想法很值得考慮。

It's worth making an appointment before you go.

去之前預約一下是值得的。

（4）It's more than one’s job's worth to do sth. 做工作所不允許的事；違反原則的事；可能丟飯碗的事

目前，這是小編發現的唯一一種worth接不定式的用法，希望朋友們加以關注。如：

It's more than my job's worth to let you in without a ticket.

沒有票就讓你進去，我可能會丟飯碗的。

2. 有關 be worthy 的搭配習慣

sth.be worthy of being done= sth. be worth doing

sth.be worthy of +n.(除金錢、時間、精力以外的其他名詞)

sth.be worthy to be done

Sb(Sth.) be worthy to do

(1) be worthy 后不能直接跟名詞、代詞或動名詞，若要接，應借助介詞 of。如：

Their efforts are worthy of your support. 他們的努力應得到你的支持。

Her behavior is worthy of praise. 她的行為是值得贊揚的。

(2) 與be worth后只接動名詞不接不定式不同，be worthy后不接動名詞，而接不定式(若該不定式要表示被動意義，則應用被動形式)。如：

He is worthy to receive such honor. 他應該得到這種榮譽。

This suggestion is worthy to be considered. 這個建議值得考慮。

(3) 若要在be worthy后接動名詞，與后接名詞時的情形一樣，應借助介詞of，且該動名詞若要表示被動意義，要用被動形式。如：

He is worthy of filling [=to fill] the post. 這個職位他當之無愧。

This suggestion is worthy of being considered [=to be considered]. 這個建議值得考慮。

3.有關 worth while 的搭配習慣

be worth-while to do sth　 "值得做某事"

It is worth while to do 花時間區做某事是值得

It is worth while doing sth花時間區做某事是值得

It is worth one’s/the while to do/doing花時間區做某事是值得

sth. be worth while 某事值得花時間去做

sth. be worth one’s/the while 某事值得花時間去做

關于worth while用法的詳細說明：

1）. worth while 的意思是：值得做，值得花時間或精力。

2）. worth while 可以有三種書寫形式：worth while, worth-while, worthwhile, 可用作表語或定語(作定語時通常要合寫一詞或用連字符，即除非用在名詞前，否則可寫成worth while)。如：

The President's trip to Washington this week seems to have been worthwhile

總統本周的華盛頓之行看來是有價值的。

考慮一下你對投保的看法也許有所助益。

Their sobering conversation brought home to everyone present the serious and worthwhile work the Red Cross does.

他們發人深省的對話使在座的每個人都清楚地認識到紅十字會所從事的嚴肅而有價值的工作。

3）. 有時可在worth與while之間插入one’s。如：

The work is worth our while. 這工作值得我們花時間(或精力)。

4）. worth (one’s) while 后可接不定式或動名詞。如：

It is worth your while to visit the museum. 這個博物館值得你去看看。

It might be worth your while to go to court and ask for the agreement to be changed

上法庭要求對協議進行改動也許對你有益。

It might be worth your while to go to court. This is tricky, though, and you'll needexpert advice.

對你來說這官司或許值得一打，不過這件事有點棘手，你需要專家的建議。

It might be worth your while to go to court and ask for the agreement to be changed

上法庭要求對協議進行改動也許對你有益。

You'll find it well worth your while to learn something of each island's special features before visiting them.

你會發現游覽之前先了解一下各島的特色非常有幫助。

在這類句型中，一般用 it 作形式主語，worth (one’s)while 之后的不定式或動名詞是句子的真正主語。在通常情況下，若句首沒有形式主語it就不宜使用此句型。如一般不會說。如：

誤：The museum is worth while visiting.

誤：The museum is worth while to visit.

請認真體會一句多譯

1. 那個地方值得一去。

正：The place is worth a visit.

正：The place is worthy of a visit.

正：It is worth visiting the place.

正：The place is worthy of being visited.

正：The place is worthy to be visited.

正：It is worthwhile visiting the place.

正：It is worthwhile to visit the place.

*worth 不可單獨作謂語（It is worth doing sth除外）worthwhile=worth while可以單獨作表語。

2. 這個問題值得考慮。

The problem is worth considering.(不用worthwhile)

It is worth considering the problem. (可換用worthwhile)

It is worthwhile to consider the problem(不用worth)
