②  在need , want , require 等少數(shù)表示“需要”的動詞后的動名詞用主動形式表示表被動意義。        
  the old man needs looking after.   the plants want watering every day.  this wall requires repairing.
  your hair wants cutting/to be cut.  the garden needs watering/to be watered. 
the floor requires washing/to be repaired . the problem requires studying with great care. (仔細研究)
(3) 現(xiàn)在分詞被動式的用法：
he asked who was the man being operated on.   that building being repaired is our library. (定語)
we saw her being taken to the operating room.  you will find the topic being discussed everywhere. （賓補）
as we approached the village we saw new buildings being built. （賓補）
having been neglected for years, the house collapsed. being protected by a thick wall,they felt they were quite safe.
having been given such a good chance, how could she let it slip away?人家給了她…，她怎么能輕易放棄呢? 狀語
the decision having been made, the next problem was how to make a good plan . 狀語
not having enough hands, they couldn’t finish the work in time. （主動）
(4) 過去分詞與現(xiàn)在分詞被動式的區(qū)別： 過去分詞表被動的同時還表完成，而現(xiàn)在分詞被動式在表被動的同時還表正在進行。  the building built last year is a hospital.   the building being built now is a hospital.
64 ing形式常見考點歸納：(1) ing形式做主語，可以將其放在句首，有時為了式句子結構保持平衡，也用it 做形式主語。 常見句型 it’s no use /no good/ useless doing sth 等句型中。
   eating too much is bad for your health.   it is no use crying.
it is necessary to be prepared for a job interview.  __ the answers ready will be of great help.
a. to have had b. having had c. have  d. having
(2) ing 形式做賓語，① 可作finish, enjoy, escape , mind, miss(錯過), imagine, consider, suggest(建議)，appreciate, mean(意味著)， risk, stop，mind 等動詞的賓語。in order to escape being punished, he made up an excuse.
i can’t __ with jane in the same office.  she just refuses __ talking while she works.
a working, stopping b to work, stopping  c working, to stop  d to work, to stop
② ing  形式還可以做短語動詞 look forward to, be used to do(習慣于), give up, get down to, be busy (in), feel like, lead to, insist on, pay attention to 等的賓語或介詞的賓語。
 isn’t it time you get down to __ the papers? a mark b be marked c being marked d marking
(3) ing形式做賓語或主語補足語。 用在動詞see, watch, feel, hear, notice, find ,catch, keep, leave , 等動詞后，或with復合結構中，作賓語補足語，表示賓語的動作正在進行。 當這些動詞變?yōu)楸粍诱Z態(tài)時，其賓語補足語就變成了主語不補足語。 we saw the boys playing near the river.   the boys were seen playing near the river.
