  10.The research is so designed that once ________ nothing can be done to change it.

  A.begins B.having begun

  C.beginning D.begunw

  解析:选D。考查分词作状语。句意:这项调查研究事先计划的如此完好,以至于一旦开始,什么也无法改变它。begin与research之间是被动关系,排除表示主动意义的A、B、C三项。once begun在句中作条件状语,它是状语从句once it is begun的省略形式。

  11.Generally speaking,________ according to the directions,the drug has no side effect.

  A.when taking B.when taken

  C.when to take D.when to be taken

  解析:选B。考查分词作状语。完整的说法应是when the drug is taken according to the directions...。由于主句的主语和从句的主语相同,因此可以省略从句的主语the drug和谓语的一部分is,故答案为B。

  12.________ into use in April,2000,the hotline was meant for residents reporting water and heating supply breakdowns.

  A.Put B.Putting

  C.Having put D.Being put

  解析:选A。考查过去分词作状语。句子的主语是the hotline与put into use“投入使用”存在被动关系,排除表示主动的B项和C项。D项表示正在投入使用,不符合语境。

  13.In order not to be found,I spent the whole night ________ in my room.

  A.locking B.locked

  C.to lock D.lock

  解析:选B。考查过去分词作状语。句意:为了不被找到,我整晚上都把自己锁在自己的房间里。lock的逻辑主语I和lock之间存在被动关系,故用过去分词作伴随状语。本题易受“spend... doing sth.句型的影响,易误选A。其实我并不是把整晚上的时间都用在了“锁”这一动作上,故排除A。

  14.________,liquids can be changed into gases.

  A.Heating B.To be heated

  C.Heated D.Heat
