热点四:动词语态
[热点透视] 结合时态、语态对考生进行综合考查;在具体语境中恰当选用语态能力。
[难点剖析] ①将构成方式为“vt. +n. + prep.”的动词短语故意变为被动语态,增加试题的干扰性。
例 Much attention should be paid to watching the patients.
②“get+p.p”也可表被动,也是考查热点。
③还有一些过去分词已转化为形容词,失去被动意义,如:hidden, dressed, lost, seated, etc. 仅表状态。
④用主动表被动几种情况:vi.(write\open\sell\re-ad,etc.) 后跟副词作状语,说明主语特征;won’t +do ,表不起作用,句子主语为物,be worth doing ,sth +needs\demands\wants+doing 表示“需要”的意义。
