　　二、虚拟语气在名词性从句中的应用 类别 用法 例句 宾语从句 宾语从句 demand，suggest，order，insist后接的从句中动词为“(should＋)动词原形”。 Teachers recommend parents not allow their children under 12 to ride bicycles to school for safety. wish后的从句中的谓语可用一般过去时、过去完成时和should/would＋动词原形，它们分别表示与现在、过去和将来情况相反。 —How much of the foreign expert’s speech have you understood？ —Next to nothing.I wish I had worked harder at English. 类别 用法 例句 主语从句 表语 从句 和同 位语 从句 在“It is necessary/important/strange/suggested/demanded/ordered/requested＋that从句”中，从句中的谓语动词用should＋动词原形。 ①It is strange that such a person should be our friend.

　　②It is suggested that the meeting (should) be put off till next week. 在suggestion，proposal，order，plan，idea，request，advice等名词后的表语从句和同位语从句中要用虚拟语气，其构成是“should＋动词原形”，should可以省略。 ①My idea is that we (should) think it over before accepting it.

　　②We all agreed to his suggestion that we (should) go to Dalian for a visit. 1．(2016·高考浙江卷)Eye doctors recommend that a child’s first eye exam ________ at the age of six months old. A．was

　　B．be C．were

　　D．Is 解析：句意：眼科医生建议孩子第一次视力检查应该在六个月大的时候进行。recommend建议，后接宾语从句时，从句用虚拟语气，谓语动词用should do形式，should可以省略，所以正确答案为B项。 B 2．(2016·高考陕西卷)My mom suggests that we________eat out for a change this weekend. A．should

　　B．might C．could

　　D．would A 三、其他句型中的虚拟语气 类别 用法 例句 It’s time that... would rather It is (high) time(that)．..句型中谓语动词用一般过去时或should＋动词原形。 Jack is a great talker. It’s high time that he did/should do something instead of just talking. would rather所接的从句中的谓语动词用一般过去时(对现在虚拟)或者过去完成时(对过去虚拟)。 I would rather you stayed at home now. 类别 用法 例句 if only as if if only后面的谓语动词常用一般过去时(对现在虚拟)、过去完成时(对过去虚拟)与过去将来时(对将来虚拟)，表示强烈的愿望。 If only our dream had come true！ as if引导的状语从句中动词可以用过去时或过去完成时表示虚拟。 Don’t handle the vase as if it were made of steel. (2016·高考陕西卷)We would rather our daughter ________ at home with us，but it is her choice，and she is not a child any longer. A．would stay

　　B．has stayed C．stayed

　　D．stay C 解析：考查虚拟语气。句意：我们宁愿我们的女儿和我们一起待在家里，但是那是她的选择，她已经不再是一个小孩子了。would rather后接that从句时，要用虚拟语气，如果与 现在或将来事实相反，从句用一般过去时态；如果与过去事实相反，从句用过去完成时。根据后面的it is her choice可以判断这件事情还没发生，因而从句用一般过去时，所以选择C项。 D 2．(2016·高考浙江卷)They were abroad during the months when we were carrying out the investigation，or they ________ to our help. A．would have come

　　B．could come C．have come

　　D．had come A
