Question

The students often________ games after class.  They ______ volleyball over there now.

A．play, are playing	B．a(chǎn)re playing, play
C．play, play	D．a(chǎn)re playing, are playing

Answer 1

A

考察時態(tài)。前文根據(jù)頻度副詞often可知為一般現(xiàn)在時態(tài)，主語students為復(fù)數(shù)，故謂語動詞用原形。下文根據(jù)時間狀語now可知為現(xiàn)在進行時態(tài)，主語they為復(fù)數(shù)形式，故助動詞be用are，選A。
