注意：當(dāng) need, want, require, worth(形容詞)后面接doing也可以表示被動(dòng)，相當(dāng)于to be done。
Your hair wants cutting. 你的頭發(fā)該理了。
The floor requires washing. 地板需要沖洗。
The book is worth reading. 這本書(shū)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(shí)意) +n /to do，need (情態(tài))+ do，當(dāng)為被動(dòng)語(yǔ)態(tài)時(shí)，還可need + doing. 本題考最后一種用法，選A。如有to be clean 則也為正確答案。
