【正文】 就太傻了。如：It’s time (that) you had a hair cut.It’s high time (that) we took some action. only引導(dǎo)的感嘆句:If only I had taken his 。例如:It is necessary( appropriate crucial desirable dreadful essential important improper incredible indispensable insistent natural preferable possible probable proper right significant surprising strange tragic urgent vital wrong etc.)that we should clean the room every day. It was a pity(a shame,no wonder,etc.)that you should be so careless. It will be desired(suggested,decided,ordered, requested,proposed,etc.)that she should finish her homework this afternoon.在上述三種主語從句中,should意為應(yīng)該、竟然,可以省去,但不可換用would。表示將來不能實現(xiàn)的愿望,用would(could)+動詞原形。例如:It looks as if our side is going to win.2. 目的狀語in order that,so that , lest ,for fear that等從句謂語動詞用 may/might,can/could)+動詞原形。虛擬語氣的用法及專項練習(xí)題虛擬語氣表示一種假設(shè)的情況，或一種主觀的愿望，即動詞所表示的動作或狀態(tài)并非事實，或不可能實現(xiàn)。例如: (1) He looks at me as if I were mad. (2) He spoke English so fluently as if he had studied English in if(as though)后的從句也常用陳述語氣,這是因為從句中的情況往往是可能發(fā)生的或可能被設(shè)想為真實的。表示現(xiàn)在不能實現(xiàn)的愿望,從句的謂語動詞用過去式。t done that.(從句用過去完成時指過去)(此句中的would可看作是表愿望的實義動詞)在主語從句中,謂語動詞的虛擬語氣結(jié)構(gòu)用should+動詞原形的結(jié)構(gòu),表示驚奇、不相信、惋惜、理應(yīng)如此等。例如(1) We all agreed to his suggestion that we(should)go to Beijing for sightseeing. (2) My idea is that he (should)do exercises first.五、虛擬語氣的幾種特殊用法：Had you asked me, I would have told you. (=If you had asked me,…)、分詞、介詞、名詞、連接詞或定語從句來表示，如：A true friend would not do such a thing.(=If he were a true friend, he...)(=If there were no water,…)(=If you hadn’t helped me,…)3. 虛擬語氣用于定語從句:It’s (high) time that…+動詞過去式或should+動詞原形， (should不能省略,be用were)來表示,意為(現(xiàn)在)該……。含蓄條件具體分為以下幾種情況:1)通過動詞不定式短語表示條件。4)通過Were it not for...或Had it not been for...等句式表達條件。(暗含條件從句if we had been more careful)It was so quiet,you could have heard a pin ,掉根針你都聽得見。 they talked D. they would talk nights.A. not watch B. must not to watch C. not be watching D. have not watch(16).
