Question

Nobody except Tom and Mary _______in the classroom. The other students are watching the basketball game on the playground now.
A. am                 B. is               C. are

Answer 1

B

考查主謂一致。在英語中，當主語后有with, together with, along with, except, besides, as well as 等短語時，謂語動詞的數要和這些短語前面的名詞或代詞的單復數保持一致。第一句中的主語為nobody，因此謂語動詞用單數is。
