no bus,we had to walk home.

There was

There being

Because there being

It being

考查独立主格结构。句意：没有车，我不得不走路回家。根据句意，表示“存在”，要用there be 句型；分析句子可知，设空处应用非谓语动词，there be只有主动形式，故用现在分词；因为非谓语动词有自己独立的的主语no bus,所以此处是独立主格结构。故选B项。

protection can lead to severe result.

being exposed

exposed

having exposed

to expose

考查非谓语动词。句意：有人警告称，在没有任何保护措施的情况下，暴露在有感染 Covid-19的人环境中会导致严重的结果。分析句子结构可知expose在句中应用非谓语动词形式，表示“暴露”短语为be exposed to,且从句中缺少主语，expose 与主语people是被动关系，故应用动名词的被动式作主语。故选A项。

One of the man holds the view          the book said was right.

that

whether

what that 

that what

考查同位语从句及主语从句。句意：其中一个人认为这本书说的是对的。分析句子可知，the view后面接了一个同位语从句（     the book said was right.），从句句子成分齐全，应使用that 引导，连接词在从句中不做成分，无意义。在同位语从句中又有一个主语从句（     the book said），在主语从句中said 缺少宾语，应用what 引导，指代“......的（事情，东西）”。故选D项。

Her father         a writer.

turned

grew
