动词时态与被动语态 一．一般现在时 (1)表示经常发生的、习惯性的动作，通常用usually，often，always，sometimes，every day，once a week等作时间状语。 I usually have my hair cut once a month. The students often do their experiments in the lab. (2)表示客观真理、格言以及不受时间限制的客观存在。 The earth moves around the sun. A bird in hand is worth two in the bush. (3)表示按时间表、计划、规定发生的动作。 The train leaves at 2：35 this afternoon. (4)主句是一般将来时的时间、条件、让步状语从句中代替将来时。 You will succeed if you try your best. Even if it rains tomorrow，the football match will take place. 1. While running regularly can’t make you live forever, the review says it (be) more effective at lengthening life than walking, cycling or swimming. 【答案】is 【解析】考查动词的时态。医学报告显示：跑步比散步、骑车和游泳更能有效地延长寿命。这里叙述的是一个事实，故用一般现在时。故填is。 二．现在进行时 (1)表示说话时正在进行的动作或存在的状态。 Our friends are waiting for us outside now. (2)表示现阶段正在进行的动作或发生的事情。 She is learning English at college. (3)某些短暂性动词，如come，go，start，open，close，arrive，return，begin，leave等用于进行时，表示按计划、安排即将发生的动作。 My father is coming to see me this Saturday. He is leaving for Beijing next week. (4)某些动词的进行时表示慢慢地、渐渐地发生变化。 I'm forgetting English. She is losing her eyesight. 1.My washing machine ___________ this week, so I have to wash my clothes by hand. A. was repaired B. is repaired C. is being repaired D. has been repaired 【答案】C 【解析】考查时态。句意：这周我的洗衣机正在修，所以我不得不手洗衣服。根据后句so I have to wash my clothes by hand.可知，洗衣机正在修，故用现在进行时态的被动语态。故选C。 2. He hurried home, never once looking back to see if he ____________. A. was being followed B. was following C. had been followed D. followed 【答案】 A 【解析】考查宾语从句和时态。分析句子成分可知，he和follow是被动关系，即他被别人跟踪，排除B、D；根据句意＂在匆忙赶回家的路上，他从未回头看是否正被跟踪＂，故用过去进行时最合适，故选A。 三．现在完成时 (1)表示过去的动作对现在的影响或结果，常用recently，lately，ever，never，once，before，yet，just等作时间状语。 He hasn't heard any news from his son lately. Have you ever been to London? (2)表示开始于过去某一时刻，一直持续到现在而且还有可能继续下去的动作。常用so far，up till now，since，for a long time，in the past/last few years，these days等作时间状语。 So far no life has been found outside the earth. He has learned 5，000 English word
