Question

【题目】A dog was seen________after a group of little ducks that should________.

A.running; take good care ofB.to run; be taken good care ofC.run; be taken good care

Answer 1

【答案】B

【解析】

句意：被看见跟着一群小鸭子跑的小狗应该被好好照顾。

考查非谓语动词和被动语态。根据see sb do sth看见某人做某事，当变成被动语态时，省略的to应加上，sb be seen to do sth某人被看见做某事，不定式做主补；that在这里代替的是a dog，做主语，和take good care of之间是被动关系，所以用被动语态，take good care of照顾；故选B。
