【正文】 hout a word. (NMET2001) ；”will+have+ed分詞”只是將來完成時的一種形式?！究祭?9。s nearly seven o39。clock. Jack ____be here at any moment. (NMET95)　 　　　　 　　　 　　　　 　　　　 【分析】should(ought to)表示很可能、預(yù)期的意思，指一種嘗試性推論，可認為是must的語氣較弱的對應(yīng)詞，意思是”應(yīng)該會、一定。吧”。試比較：Our guests must be home by now.(‘I am certain’)我們的客人現(xiàn)在一定到家了。（根據(jù)他們動身的時間、路程遠近、速度等具體條件，我能斷定/肯定他們現(xiàn)在已經(jīng)到家了。）Our guests should(ought to) be home by now.(‘They probably are,but I’m not certain.)我們的客人現(xiàn)在該到家了。（含義是我想他們很可能到家了，但我不能肯定”）與must不同還在于它常常表示將來：When can I e for the photos?I need them tomorrow afternoon.They_____be ready by 12:00. (NMET1998) 表示不太可能可用shouldn’t(oughtn’t to):There shouldn’t(oughtn’t to) be any 。析：填C。意思是”將近七點了。杰克很可能隨時會到?！薄?另外，在近幾年的NMET中，對情態(tài)動詞及其它語法項目的考查均放到一定的語境中進行，要求考生利用所學(xué)英語各項基礎(chǔ)知識進行初步的語言運用，而不再是單純的語法知識題和短語題。這類試題往往通過題干的其他部分或附加句子提供某個信息，然后讓考生根據(jù)這個信息進行合理推理，產(chǎn)生新的想法和認識。因此，在做這類題時，除要熟悉所考查的語法規(guī)則外，還要認真分析句子的結(jié)構(gòu)，注意抓住關(guān)鍵詞，分析上下文的邏輯關(guān)系。不能單憑語法規(guī)則做題。 鞏固練習(xí) __ be a policeman, for he39。s much too short.
