7、lthy核心语法 1.含有情态动词的被动语态2情态动词表推测的用法(must，cant，might，could) without为介词，意思是“没有；不带”，后常跟名词、代词或现在分词，其反义词为with，意思是“有，和一起”。stop用作动词，意为“停止；阻止”。其用法如下：(1)stop doing sth.停止做某事。如：Our teacher is coming.Please stop talking.我们的老师来了。请不要讲话了。(2)stop to do sth.停下来去做某事。如：Whats happening？Lets stop to have a look.发生什么事？我们停

8、下来去看看吧。(3)stop sb.from doing sth.阻止某人做某事。如：We must stop the kids from swimming here.我们必须阻止小孩在这里游泳。情态动词表推测主要有以下几种情况：(1)在肯定句中可用must，could，may，might对现在的情况进行推测，其中must表示完全肯定，could，may，might所表示的可能性依次递减。must be意为“一定是”，could/may/might be意为“可能是”。(2)can用来表示对现在情况的推测或判断时，只能用于疑问句或否定句，cant be意为“一定不是”。(1)not onlyb

9、ut also是一个连词结构，意为“不但而且”，相当于bothand，在句中连接并列成分，有时可以省略also，其反义短语为neithernor。如：Not only you but also he speaks Japanese in our class.不仅你说日语，而且他也说日语。(2)not onlybut also连接并列主语时，谓语动词遵循“就近原则”。如：Not only Tom but also I speak Japanese.不仅汤姆而且我也说日语。(3)not onlybut also可以连接相同的句子成分或者并列分句，在连接两个简单句时，not only可以放在句首，这

10、时句子要用部分倒装。即将谓语动词的一部分(如：情态动词、助动词do，does，did，have，has，had等)放在主语的前面，而but(also)后的句子用陈述语序。如：Not only did he say so，but also he did so.他不仅这样说，也这样做了。 a number of/the number of【考点抢测】10How many women doctors are there in your hospital?_ them _ over twenty.(2015，益阳)AA number of，are BThe number of，areCThe numb
