（2）on表示地点、位置,有“在.旁”、“接近”、“靠近”之意.如：

（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.

“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：

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。

第二、that 用作代词。

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.

is there anything that i can do for you?
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。
i didn't expect (that) he could win the championship.
the teacher pointed out that tom was not working hard enough.

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。
the trouble is that we are short of money.
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. that引导状语从句
①引导目的状语从句。

第四、that用作副词。

4. seeing that，意为“鉴于、由于”。

seeing that he was busy with his work, i didn't disturb him.
篇12：as用法总结

He shouted aloud as her ran along.他一边往前跑，一边高声地呼喊。
I was startled as he opened the door.他一开门，我吓了一跳。
as作连词，相当于when。eg;
As a little boy (When he was a little boy)he began to learn to play piano.他小时候就开始学弹钢琴。
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。
3.引导方式状语从句或比较状语从句，作“正如，(如)像”解。例eg：
As in your country，we grow wheat in the north and rice in the south.正如(像)你们国家一样，我们在北方种小麦，在南方种大米。(方式状语从句)
When at Rome，do as Romans do.入乡随俗。(方式状语从句)
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;
Strange as it may seem，it is true.尽管这事看上去很奇怪，但却是真的。
Try as he might，Tom could not get out of the difficulties.不管怎样努力，汤姆还是摆脱不了困境。
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13：that用法总结
that还常用以代替who, whom, which,但that...which中的that用做关系代词的先行词。
