最近也有其他学生问过这个问题,it's time that...的虚拟语气格式是后面的从句用过去时或者should + v. ,也有could+v.的情况,在高中主要考查的是前两种。您说的情况的确存在,各种语法书也说法不一,有的赞同用were或者was都行,有的不赞同用were,只能用was。在目前中学考查中这种结构我还没有见过用were的。&nbs...

if引导真实条件句还是虚拟条件句,取决于说话者个人内心的倾向,如果说话人认为所说的事情可能会发生,就用真实条件句;如果说话人是纯粹假设或者认为发生的可能性不大,就用虚拟条件句。这关乎到语境的问题。作为外语的学习者要逐渐认识到这一点。因为我们国家的教育体制是应试教育,学生很多死记硬背语法规则,对于活学活...

I think the book to be interesting.这个句子之所以不对,是因为think在主动语态中一般不与不定式结构连用,但是在被动结构中,可用不定式,请看您所给的正确句子。我再用“think + 宾语 + 形容词 / 名词(宾补)”这种结构说明一下:I think him very wise. 我认为他很明智。(主动句子him后面不用不定式)改成被动:He is...

我从句法上区别一下:■It is agreed that…it是形式主语,that引导真正意义的主语从句,这个结构中的be agreed是被动结构,也就是说,agree是动词。例如:It was agreed that another meeting was necessary. 大家一致认为有必要再开一次会。= We agreed that another meeting was necessary. ■sb. be agreed that…agreed在...

根据章振邦教授编写的《新编英语语法》指出:连词that很少用来引导原因状语从句,但在某些表示情感的不及物动词之后,that 分句说明这种情感产生的原因,因而可以看作原因状语分句。例如:I rejoice that you are coming home. 你要回家我很高兴。I grieve that he has lost his dear child. 他失去了孩子我很悲伤。在以...

especially可以修饰时间或者原因状语从句,根据《麦克米伦高阶》:especially + if / when / as / while / because / since…,例如: He did not want to upset his father, especially as his mother was so ill. 他不想让父亲烦心,尤其是在母亲病得这么重的时候。 You will need to book your ticket in a...

have to 用于现在完成时的例子并不少见。例如: We have had to turn down four applicants already. 我们已经不得不回绝了四位申请人。 Not all companies have had to cut back on training. 不是所有公司都得削减培训费用。 Since his illness. He has had to swear off tennis. 他自从患病以来不得不停止打网...

您给的例句的确是不定式作宾语。在章振邦教授编著的《新编英语语法》中指出:能直接跟有to不定式结构作宾语的动词,常见的有:afford, agree, aim, apply, ask, arrange, choose, claim, decide, decline, demand, desire, determine, expect, hope, learn , long, manage, offer, pretend, promise, refuse, seek, threate...
