B 由答語的時(shí)態(tài)為現(xiàn)在進(jìn)行時(shí)態(tài)可推知，問句也應(yīng)為現(xiàn)在進(jìn)行時(shí)態(tài)，構(gòu)成為be+doing。故選B。2. D 由now詞可知用現(xiàn)在進(jìn)行時(shí)。主語為兩個(gè)人，be動詞用are。3. C 根據(jù)Look可知用現(xiàn)在進(jìn)行時(shí)，some people是復(fù)數(shù)形式，故選C。4. D 根據(jù)題干可知，and應(yīng)連接相同的成分，sit的現(xiàn)在分詞應(yīng)為sitting，故排除B、C兩項(xiàng)。又因?yàn)楝F(xiàn)在進(jìn)行時(shí)中應(yīng)含有be，故選D。5. D 句意：爸爸在哪？他正在床上打電話？表示此時(shí)此刻正在發(fā)生的動作，要用現(xiàn)在進(jìn)行時(shí)。故選D。6. B 根據(jù)句意“請安靜”可推知“爺爺正在睡覺”，需用現(xiàn)在進(jìn)行時(shí)態(tài)，構(gòu)成為：be+ V-ing。故選B。7. C 主語為復(fù)數(shù)，所以be動詞用are。8. D 本題考查現(xiàn)在進(jìn)行時(shí)表將來，故選D。9. C 根據(jù)often可判斷第一句話是一般現(xiàn)在時(shí)；根據(jù)時(shí)間狀語now可知后一句是現(xiàn)在進(jìn)行時(shí)態(tài)。3
