26、使用已被拆除。根據(jù)時間狀語Up to now可知設(shè)空處需用現(xiàn)在完成時;主語thousands of red phone boxes與remove之間為被動關(guān)系，故需用被動語態(tài)，故答案為D項。3.答案C解析句意: 瞧，已經(jīng)有人打掃了沙發(fā)。嗯，不是我，我沒做過那件事。本題考查動詞時態(tài)的基本用法。根據(jù)Look!可知，設(shè)空處表示現(xiàn)在的情況，故用現(xiàn)在時，排除B、D兩項; A項表示現(xiàn)在正在進行，不符合句意要求?，F(xiàn)在完成時表示該動作對目前所造成的影響或結(jié)果，即現(xiàn)在沙發(fā)很干凈。4.答案B解析句意:你猜我是誰?抱歉，我想不起你的名字了。根據(jù)句意可知說話者現(xiàn)在不知道對方的名字，故設(shè)空處表示現(xiàn)在的情況，需用現(xiàn)在時，

28、的?所有申請人要被面試后才能由專家做出最終的決定。本題考查動詞的被動語態(tài)。applicants和interview之間是被動關(guān)系，排除A和B項;語境是在描述工作流程，應(yīng)用一般現(xiàn)在時。9.答案B解析句意為:我記得昨晚把筆記本落在書房了。它怎么跑到這里了?哦，我以為你需要它，所以就給你帶來了。根據(jù)答語可知，come所表示的動作已經(jīng)發(fā)生，要用現(xiàn)在完成時。故B項正確。10.答案D解析句意:這是我第三次來大連了。在This / It is the third time that .這個句式中，從句要用現(xiàn)在完成時，即has / have done,因此選擇D。三、單句語法填空。答案1.has been decorated2.have been selected3.have been set4.have taken, have been set5.has been tried6.have been given7.have been made8.have been produced9.has been reach
