She is a teacher and works at the college._______.
A.So is Li Ming B.So does Li Ming
C.So is it with Li Ming D.So it is with Li Ming
为什么不选B

优质解答

答案选C.
问句是由两个句子组成的,she is a teacher ,是系表结构的句子；she works at the college,是主谓结构的句子,是两种情况,用it可以代替这两种情况.
A答案So is Li Ming只能用于回答前半个句子：She is ateacher.因为都是be动词.
B答案So dose Li Ming只能用于回答后半个句子：She works at the college.work是实意动词由dose代替.
D答案So it is with Li Ming,这个句子是正常语序,不能用于回答不同的人相同或者不同的情况.
