 about around round 作副词时都含“四处”、“遍地”的意思。

i have been looking for it all around. 我到处都找过了。
 另外, 英国人用 round的地方, 美国人倾向于用 around, 如:

he failed after all.他终于失败了。
 at all用于否定句时,意为“丝毫;根本”,用于疑问句时意为“究竟;到底”,用于条件句时,常译为“当真;实在”。用于肯定句中,表示说话人的某种情绪或情感(如怀疑或惊奇等),意为“竟然”等。如:

 add; add to; add…to; add up to

 add to意为“增添,增加,增进”。如:

 a great deal; a great deal of
 a great deal用作名词,意为“大量”,“许多”,作主语、宾语;用作副词,意为“很”或“非常”,作状语,修饰动词或用来强调比较级。如:

 agree on;agree to;agree with;agree that
 agree on作“就……取得一致意见”解。例如:
the building of a new car factory was agreed on last month.
上月,就建一座新汽车厂之事达成了协议。
 agree to有两层含义和用法:
 其一是to作为动词不定式符号,其后跟动词原形,作“同意(答应)做某事”解。
例如: my father agreed to buy a new pen for me. 父亲答应给我买支新钢笔。
 其二是to作为介词,之后跟表示“计划/条件/建议等一类的名词或代词”。例如:
they have a greed to our plan. 他们已同意我们的计划。
 agree with作“同意某人的意见”解,其后可跟表示人的名词或代词,也可跟表示“意见”或“说的话”的名词或从句。例如:

 agree that作“认为……”解,其后跟宾语从句。例如:

 allow;let 二者均可作“允许”解,但各有侧重:  allow重在“允许”或“容许”,也可表示客气的请求。例如: he allowed me to take his dictionary.他允许我拿走他的词典。 will you allow me to use your bike? 我可以用你的自行车吗?  let作“允许”或“让”解,主要用于口语,一般可与allow互换。作“允许”解时,常暗含“听任”、“默许”之意;作“让”解时,常含“祈使”或“建议”之意。注意:let之后作宾补的不定式不带to,且不可用于被动语态,而allow则相反。例如: please let me walk with you(=please allow me to walk with you.).我(请允许我)跟你一起走。注:allow常用于allow sb.to do sth.或allow doing sth.结构中。
 although; though; as
三者均可表示“尽管;虽然”,引导让步状语从句。although用法较正式,语气较强;though较常用;as则主要用于倒装句。它们的用法有如下几点值得注意:
 状语从句由although, though或as引导,主句之前不可有but, and, so, however等并列连词,但可有yet或still等副词。although与though常可互换。例如:
although/though he believes it, yet he will not act. 他虽然相信它,但却不肯有所行动。
 as表示“尽管;虽然”,只能用于倒装句,即:将表语、状语或谓语动词放在as之前。though也可这么用。例如:
young as/though he is, he knows a lot. 他虽然年纪不大,却懂得很多。
注意:如果表语是单数名词,要省略a。例如:
child as/though he is, he can speak two foreign languages. 虽然他是个孩子,但他会说两门外语。
 though可以放在句末,表示“但是”,although却不能。例如:
they said they would come; they did not, though. 他们说他们会来,可是他们并没有来。
 although只用来陈述“事实”,不能表示“假设”。因此可以说even though“即使”以及as though“好像(=as if)”,不能说even although或as although。例如:
i believe you are on duty—even though you’re in plain clothes. 尽管你穿着便衣,我相信你是在值勤。
 among/between
这两个介词都有“在……之间”的意思。between常用于两者之间;among一般指三者或三者以上之间。若指三个以上人或物中的每两个之间时,仍然要用between。
例如:the girl walked between her father and mother.这个女孩走在她父亲和母亲之间。
she is the tallest among her classmates.她在她同学之间是最高的。
switzerland lies between france,italy,austria and germany.
瑞士位于法国、意大利、奥地利和德国之间。
 argue debate dispute 都含“辩论”的意思。
 argue 着重“说理”、“论证”和“企图说服”, 如:

我和她辩论了好久, 但她还是不听。
 debate 着重“双方各述己见”, 内含“交锋”的意思, 如:
we have been debating about the issue. 我们一直在就这个问题进行辩论。
 dispute 指“激烈争辩”, 含有“相持不下”或“未得解决”之意,如:

 argue;quarrel;discuss
这三个动词均有“争”的意思,但“争”法不同。
 argue着重就自己的看法或观点,提出论证,同他人“争论”或“辩论”。例如:

另外,argue同with搭配,其后接人;与about连用,其后接事物。例如:

 as (so) far as; as (so) long as
 as(so)far as的意思是“就……而言(所知)”,as (so) far as sth.is concerned是其中一种具体用法,意为“就某事而言”;as (so) long as意为“只要”,引导条件状语从句。如:

如:我们不能说:an asleep baby,但可以说:a sleeping baby(一个熟睡的婴儿)。
再如:he was asleep with his head on his arms.他头枕着手臂在熟睡。
