need/want/require/worth
| 12.7 need/want/require/worth | ||
| 注意：當 need, want, require, worth(形容詞)後面接doing也可以表示被動。 Your hair wants cutting. 你的頭髮該理了。 The floor requires washing. 地板需要衝洗。 The book is worth reading. 這本書值得一讀。 典型例題 The library needs___, but it'll have to wait until Sunday. A. cleaning B. be cleaned C. clean D. being cleaned 答案A. need (實意) +n /to do，need (情態)+ do，當為被動語態時，還可need + doing. 本題考最後一種用法，選A。如有to be clean 則也為正確答案。 典：done，"不可能已經"。must not do 不可以（用於一般現在時)。 | ||
