2016届高考英语二轮语法突破课件：情态动词与虚拟语气（外研版）

　　③It’s usually warm in my hometown in March，but it ______ be rather cold sometimes. 剖析：can　句意：三月份，我的家乡通常比较温暖，但有时也非常寒冷。本题考查can用在肯定句中表示“一时的或暂时的情况”。方法二：正确把握某些情态动词的特殊用法。在有些情况下，可能用好几个情态动词都合理，但有些情况下，必须是唯一的。如：can not(never)＋动词＋too＋adj./adv.，can not(never)＋动词＋(adj./adv.)＋enough(再……也不为过)；can't help doing(禁不住干……)；can't help but do.../can not but do(不得不做……)；may/might well(很可能)；may/might as well(还是……为好)；How could it be...(怎么可能)；Why/How should＋(人称代词he，she...)＋陈述句(表示说话人对某事感到意外)；should表示“竟然”，must表示“硬要，一定要”。

　　[典题示例] ①My mother is a great cook and we ________ never get enough of her cookies. 剖析：can　句意：我妈妈是个很棒的厨师，我们永远吃不够她做的饼干。can not/never与enough连用，表示“再……也不为过”。

　　②Mr.Bush is on time for everything.How________ it be that he was late for the opening ceremony? 剖析：could　句意：布什先生干任何事情都很守时，开幕式他迟到了，这怎么可能？How could it be...？“怎么可能……？”为常用搭配。若第二句改为How ________ he be late for the opening ceremony？就应该选用should表示“竟然”。虚拟语气一、考点知识归纳考点一　虚拟语气在非真实条件句中的应用虚拟条件句主句与现在事实相反的假设 If＋主语＋动词的过去式(be动词用were) 主语＋should/would/ could/might＋动词原形与过去事实相反的假设 If＋主语＋had＋过去分词主语＋should/would/ could/might＋have＋过去分词虚拟条件句主句与将来事实相反的假设 ①If＋主语＋动词过去式(be动词用were) ②If＋主语＋were to＋动词原形 ③If＋主语＋should＋动词原形主语＋should/ would/could/might＋动词原形 If I had time, I would attend the meeting. 如果有时间，我就会参加会议。 If I were you, I should seize the opportunity to go abroad. 如果我是你，我就该抓住这次出国的机会。 If I had taken your advice，I would not have failed in the exams. 如果我听了你的劝告，我就不会考试不及格了。 If you came tomorrow，we would have the meeting. 如果你明天来，我们就开会。 If it were to rain tomorrow，the sports meeting would be put off. 如果明天下雨，运动会将会推迟。 If he should not come tomorrow，we should put off the meeting till next Monday. 如果他明天不来，我们就将会议推迟到下周一。
