问题补充：

his being late again, he lost his job and had to stay at home.

A. Because

B. As result of

C. In case that

D. Because of

答案：

A. Because

B. As result of

C. In case that

D. Because of

解析：句意：因为他又迟到了，他失去了工作，只好呆在家里。his being late again是动名词的复合结构，用because of连接，because是连词，后面接从句，B项应该是as a result of，C项是以防，所以选D。
