Question

【题目】Every year, we invite many doctors to give lectures on keeping fit and healthy. (改为被动语态)

Every year, many doctors ________ ________ to give lectures on keeping fit and healthy.

Answer 1

【答案】are invited

【解析】

句意：每年，我们都邀请很多医生来做关于健身和健康的讲座。

此句是一般现在时态的陈述句，改为被动语态，要用助动词be+动词的过去分词，根据主语many doctors是复数形式，故答案为（1）are（2）invited。
