as if 用法
一、as if 从句的作用
1. 在look, seem 等系动词后引导表语从句。
如：

那孩子跟我们谈起话来，像个成年人似的。
二、as if 还可用于省略句中如果as if 引导的从句是“主语+系动词”结构，可省略主语和系动词，这样as if 后就只剩下名词、不定式、形容词(短语)、介词短语或分词。
如：

从他谈话的样子来看他是醉了。
2.as if 从句用虚拟语气的情况。 当说话人认为句子所述的是不真实的或极少有可能发生或存在的情况时。从句虚拟语气动词时态的形式如下：

如：
You look as if you didn’ t care.
你看上去好像并不在乎。
He talks as if he knew where she was.
他说话的样子，好像他知道她在哪里似的。
(2)从句表示与过去事实相反，谓语动词用“had+过去分词”。
如：

他说起罗马来好像他以前去过罗马似的。
The girl listened as if she had been turned to stone.
那女孩倾听着，一动也不动，像已经变成了石头似的。
(3)从句表示与将来事实相反，谓语动词用“would/could/might+动词原形”。

他张开嘴好像要说什么。
It looks as if it might snow.

篇5：on用法总结
（2）on表示地点、位置,有“在.旁”、“接近”、“靠近”之意.如：
a house on the main road 临大街的房子,sit on my right 坐在我的`右边
（3）on表示状态,译为“处于.情况中,从事于.”等.如：
on duty 值日,on holiday 度假
（4）on表示“在.上面”,用在表示物体的名词前.如：
on the box 在盒子上
on和over都是介词,on表示“在.上面”,指一物体与另一物体表面相接触；over表示“在.上方”,指一物体与另一物体不接触.试比较：
There is a light on the desk．桌子上有盏台灯.（light与desk接触）
There is a light over the desk．桌子上方有一盏灯.（light与desk不接触）
表示“在.上”,介词on与in必须注意习惯用法,否则会出错.不妨比较一番：
on the tree／in the tree都译为“.在树上”.前者表示树上本身所长着的叶子、花、果实等；后者表示某物或某人在树上.
on the wall／in the wall都译为“在墙上”.由于介词不同,在使用上有区别.图画、黑板、风筝等“在墙上”,是因为它们在墙的表面上,故用on the wall；门窗、钉子、洞、孔等“在墙上”,是因为它们在墙的里面,故用in the wall.

篇7：THAT用法总结
“that”在英文中是一个使用频率很高的单词。它有四种词性，并且句法及语法功能纷繁复杂。同学们如果不能熟练掌握其用法，很可能会形成英语学习的一种障碍，从而影响其学习兴趣和效率。现将that的用法总结归纳如下：
第一、that 用作形容词（后接复数名词时用those）。
它用来指已被提到的人或物；也可表对比，指两个中较远的那个。
what about that book you borrowed from me last month？
请注意，that 有时候在句子中具有喜欢或轻蔑等感情色彩。
that little son of his 他那个小宝贝儿子
that george！乔治那家伙！（含有轻蔑语气）
第二、that 用作代词。
1. that 用作指示代词（复数形式是those），其指代意义同形容词用法，同时它还可以用作定语从句中的先行词；还可为了避免重复，代替前述名词。
that is what he told me.
what is that (which) you have got in your hand?
the price of rice is higher than that of flour.
2. that 用作关系代词，引导限制性定语从句。先行词可人可物，用法相当于who或which。（但是在下列情况下多用that：先行词既有人又有物时；先行词有形容词最高级、序数词、不定代词、very，only等修饰时；先行词是不定代词时）
he talked about the teachers and schools that he had visited.
i think it one of the most wonderful films that the film company has ever produced.

请注意，that 在定语从句中作宾语时通常可省略。

第三、that 用作连词，引导名词性从句,状语从句和强调句。
1. that名词性从句。
①引导宾语从句。及物动词后的引导词that可省略。

that the earth goes around the sun is known to everyone.
（it is known to everyone that the earth goes around the sun.）
③引导表语从句。

④引导同位语从句。
引导同位语从句的that和引导定语从句的that是不同的。前者只起语法作用，在从句中不作任何成分；而后者在定语从句中作主语、宾语或表语。举例说明：
the news that he resigned from office surprised us.
the idea that he holds is very common nowadays on campus.

2.引导原因状语从句，作“因为，由于”解，与because的用法相近。eg;
I must stop writing now，as I have rather a lot of work to do.我必须停笔了，因为我还有许多工作要做。

4.引导让步状语从句，作“虽然，尽管”解。这时从句常用倒装语序，即把从句中的表语、状语或动词原形放在as之前。eg;

四)as作关系代词。
1.引导限制性定语从句，用在“such...as”,“the same...as”，“as...as”等结构中，常译作“像...一样的人(或物)”，“凡是...的人(或物)”。例eg：
He wished to be such a man as Lei Feng was.他曾希望做一个像雷锋那样的人。
My hometown is no longer the same as it was.我的家乡再也不像过去一样了。
2.引导非限制性定语从句，用来指代它前面的整个句子(即先行句)，意思是“这一点”。这个分句可以位于句首、句中或句末。eg：
As is well known，oceans cover more than 70% of the earth.我们知道，海洋占地球面积的百分之七十以上。
篇9：that用法总结

that可以用作连词
that用作连词时可引导主语从句、宾语从句、表语从句、同位语从句和状语从句。
