— He, together with his parents going to visit Shanghai in July. How about you?

— Im afraid I have to stay at home __.

A. are; on my own

Bis, by myself

C. is; by my own

D. are; on myself

答案：

A. are; on my own

(答案→)B. is, by myself

C. is; by my own

D. are; on myself

解析：就进原则与by oneself的用法。介词with后的谓语动词应和它前面的主语he一致，故A,D错。by oneself是“独自”的意思。故选择B。
