高二英语必修5Unit3语法训练题(含答案)

munication skills.
A．Knowing B．Having known
C．Known D．To be known
解析：选C。 be known as被称为……。Dr Lillian Glass与know之间为被动关系，应用过去分词形式作状语。A、B表主动，应排除；D项表将来，也可排除。
8．________ more attention，the trees could have grown better.
A．Given B．To give
C．Giving D．Having given
解析：选A。考查分词作状语。句子主语the trees与give之间是被动关系，而四个选项中只有A项表示被动意义，故答案选A。Given more attention相当于一个条件状语从句If the trees were given more attention。
9．________ in thought，he almost ran into the car in front of him.
A．Losing B．Having lost
C．Lost D．To lose
解析：选C。考查分词作状语。句意：由于陷入沉思，他差一点撞到前面的车上。be lost in thought为固定搭配，意为“陷入沉思”。过去分词短语lost in thought在句中作原因状语。
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
解析：选C。考查过去分词作状语。句意：被加热时，液体可以变成气体。由于对于液体来说是加热的承受者，是被动的，因而选C。A项表示主动，B项表示目的，D项是谓语动词的形式。
15．Unless ________ to speak，you should remain silent at the conference.
A．invited B．inviting
C．being invited D．having invited
解析：选A。考查过去分词作状语。句意：除非受到邀请讲话，否则在大会上你应该保持沉默。invite与you之间是被动关系，排除B、D。being invited表示正在受到邀请，不符合语境。
