Question

_____________ ill, he did not take part in the sports meeting last week

_____________ ill, he did not take part in the sports meeting last week
A. Be B. Being C. To be D. To have been

Answer 1

答案选B
Being+形容词：现在分词短语表示原因，相当于
Because he was ill, he did not...
A原形，用于名首时，是祈使句的。这里不对的。
C目的状语
D动词不定式完成式，意思不对的。

Answer 2

_____________ ill, he did not take part in the sports meeting last week
A. Be B. Being C. To be D. To have been

答案解析: 答案为B
以上是非谓语动词做状语用法, 其逻辑主语位于句子主语, BE 需要用现在分词结构,作原因状语, 可以改为原因状语从句

Being ill, he did not take part in the sports meeting last week

=Because he was ill,he did not take part in the sports meeting last week

Answer 3

B 现在分词做原因状语，对后面的句子作解释
