湖南隆回一中 罗玉南 五、should在虚拟语气中的运用 1、在if引导的条件状语从句中，若表示与将来事实相反的假设，条件句的谓语动词可以用“should ＋动词原形”；若if省略， should应提到句首，构成部分倒装。例如： If it should snow tom orrow ，the m eet- ing would be put off． 如果明天下雪的话，运动会就会推迟。 13．_____it rain tomorrow，we would have to put off the visit to the Yangpu Bridge．（94上海）A．WereB．ShouldC．Would D．Will 2、动词arrange（安排，筹划），command（命令，要求），demand（要求，需要），desire（要求，渴望），insist（坚决主张），order，propose（主张，提议），request，require，suggest（建议）等后跟宾语从句时，谓语动词应用“（should）＋动词原形”。例如： 14．The guard at the gate insisted that everyone __________ the role．（MET85） A．obeyingB．obeyC．will obeyD．would obey 15.Jane's face suggested that she __________ ill，and her parents suggested that she______ a medical examination．（95上海）

3、名词advice，idea，order，demand， plan，proposal（主张），suggestion，request等后跟表语从句或同位语从句时，其谓语动词用“（should）＋动词原形”。例如： We all agreed to his suggestion that we（should）go to Hangzhou for sightseeing． 我们都同意他的建议我们应该到杭州去观光旅游。 My advice is that we（should）do more eye exercises every day． 我的建议是我们每天应该多做眼保健操。 4、在主语从句的下列三种句型中，主句的谓语动词应用“（should）＋动词原形”。 （1）It is necessary（important，impossible，strange，natural．．．）that．．． （2）It is a pity（a shame．．．）that．．． （3）It is suggested（requested，ordered，desired．．．）that．．．例如： It is necessary that we should send for a doctor．我们很有必要派人请个医生来。 It is requested that Miss Gao（should） give a perform ance at the m eeting． 人们要求高小姐应该在大会上进行一场演出。 It is a pity that he（should）be so careless．他竟如此粗心真是令人遗憾。 六、should可以用来表示惊奇、惶惑、不满、惋惜、忧虑等情绪。例如： 16.You can't imagine that a well-behaved gentleman ________be so rude to a lady．（2001上海）A．might B．need C．should D．would Never did he expect that the conditions should be so terrible．他从来没有料到情况竟如此可怕。 Should you like to drink some beer？你是否喜欢喝点啤酒？ He should expect their team to win the match．他倒是希望他们队能赢得这场比赛。 八、should可以用于较强语气的假设情形中，表示“竟然；万一”之意。例如： If he should fail to come，ask John to go there in his place．万一他不能来就叫约翰代替他去。 Should it blow hard，we would not go out for a picnic．万一明天刮大风，我们就无法去野餐了。 九、should用于目的状语从句或in case引导的条件状语从句中时，相当于might，含有“会；可以”之意。例如：They got up early so that they should catch up the first flight in time． 他们很早起床以便能及时赶上首班飞机。 He took him along with an umbrella in case it should rain． 他随身带了一把雨伞，以防天可能下雨。 又如： -The room is so dirty． ＿＿＿＿＿we clean it﹖ -Of course．(北京2003) A． Will B． ShallC． WouldD． Do 简析：问句表示征求对方的意见，故本题选B。 It’s nearly seven o’clock． Jack＿＿＿＿ be here at any moment．(NMET’95) A． mustB． need C． shouldD． can

热点五：“情态动词＋have＋过去分词”常见句型及用法 句型1：should (ought to) have＋过去分词 表示过去应该做而（实际）没有做的事情。含有责备或遗憾的语气，意为“本应该……”。其否定形式为“should not／ought not to have ＋ 过去分词”。如： We ＿＿＿＿ last night，but we went to the concert

time． She ＿＿＿＿＿．(MET’87) A． mustn’t have hurriedB． couldn’t have hurried C． must not hurry D． needn’t have hurried 简析：本题的前一句暗示了一个条件，后一句则是由这个条件得出的结论。故本题选D。 句型3：must have＋过去分词 意为“过去一定做过某事”，表示一种很有把握的推测。注意，对过去发生情况的否定推测常用can’t／couldn’t have ＋过去分词。如： I didn’t hear the phone． I ＿＿＿＿＿＿asleep．(MET’89) A． must be B． must have beenC． should beD． should have been
