question和problem的不同用法
嗯嗯...介两个是很有区别的~
Problem是名词,通常指生活中的困难,不过也有指书本上的难题。
例句:She spent all day trying to solve this technical problem.
她花了一整天尝试着解救这个技术问题。
Question可以作名词,通常指提出的问题或者是疑问。
例句:You can ask the teacher if you have got any question.
如果你有任何问题,你可以问老师。
不过Question也能做动词,表示向某人提问。
例句:She questioned me something about the technical problem.
她向我询问了一些关于技术问题的事。
有例句应该比较易懂一点吧↖(^ω^)↗
as的不同用法和不同用法的区别。 只要as!
一、as作介词
1. 区别as和like
as作为介词时,可以表示“像……”,这时它可以和like互用;as还可以表示“以……身份”或“作为……”,“当作……”,但like不能。
e.g. I) They lived and fought among the people as “fish in water”. (as相当于like)
II) As a scientist, he was dedicated to (致力于) the truth. (这里不可以用like)
II) They talked as old friends. (他们确乎是老朋友。)
à They talked like old friends. (他们像老朋友一样。)
2. as引导的介词短语在句中可以充当:
a) 宾语补足语
e.g. I) She spoke of me as her dearest friend.
II) The plan struck me as very much worthwhile.
III) You mustn"t think of me as (being) unhappy.
b) 主语补足语
e.g. I) She is well-known as being very cheerful.
II) He is sometimes portrayed as belonging to another century.
III) That picture is looked upon as very valuable.
常用于这类结构的动词有:aept, consider, describe, elect, interpret (理解), look upon, perceive, recognize, refer to, regard, see, strike, take, think of, treat, view等等。
for和to的不同用法
for表示“为了…”一般是for *** ,to表目的时是“todosth"
problem可数吗?还是有不同用法?
problem可数,复数是 problems,详细信息如下:
problem英 [ˈprɒbləm] 美 [ˈprɑ:bləm]
n.问题;疑难问题;习题;引起麻烦的人
adj.成问题的;难处理的;关于社会问题的
例句:
The main problem is unemployment
主要的问题是失业。
In some cases a problem child is placed in a special school
有时,问题儿童被放在特殊的学校。
this that 和these those的不同用法
单数用 that this 表示 这个 那个
that 还多用于 宾语从句 例如

that 还可表示强调句
It is the information that i really want
复数 用 these those
用法较单一
a quantity 和 queantities of的不同用法
- quantities of无论修饰可数还是不可数名词、谓语动词都用复数.
例如:
Quantities of food (nuts) were on the table.桌子上有许多食品(坚果).
-
a quantity of+可数名词复数、谓语动词用复数;+不可数名词、谓语动词用单数.即修饰可数或不可数名词均可,作主语时采取就近一致的原则,其谓语动词通常与短语中of后面的名词的数保持一致.
例如:
A large quantity of beer was sold out.大量的啤酒被售出.
A large quantity of blouses were on sale.大量罩衫有售.
return和back的不同用法
你想问的应该是这两个词都作为动词的时候的区别吧(因为back还有其他词性) back作为动词时及物动词 vt.
1. 使倒退;使后退
She backed her car out of the garage.
她从车库倒车出来。
2. 支持;援助;赞助
A lot of my friends backed my plan.
许多朋友支持我的计划。

约翰立即背书这张支票。
不及物动词 vi.
1. 倒退;后退
On seeing the dog, she backed away.
一见到狗,她便向后退去。
2. 【海】(风)逆时针转向 back的具体用法 :docin./p-192649524. return vi. 1.回, 返回 return home回家(乡); 回国 2.送还 The property returned to the original owner. 财产已还原主。 vt. 1.寄回、放回或带回: We return bottles to the store. 我们将瓶子送还商店 2. 回报给予或赠送以作为回报: She returned his praise. 她回报了他的夸奖 3.归还还给主人: He returned her book. 他归还了她的书 4.反射或送回: The echo was returned by the canyon wall. 回声是峡谷壁传回来的 做及物动词的时候,后面直接跟宾语; 做不及物动词的时候,后面不跟宾语,就是单独用。 或者要跟宾语的话,后面加介词to再跟宾语。 return用法:1“返回”,相当于“go back / get back / e back.. 如:Ann will visit you when he returns to London. (当“返回”时是不及物动词,先加to才可再加地点。另外,return已含有back的意思,后不可再跟back.) 2“归还”,相当于“give back”如:I have returned the dictionary. (当“归还”时是及物动词,后直接加物,若再接人时方可加to. 同样不可再跟back. 如:You should return the piano to Dick on time.)
see,watch,look的不同用法。let"s,let us的不同用法。
see是最常用的看 及物动词 I see还可以翻译成 我明白了
watch如果对比这三个词 它是带有观赏性的观看 比如 watch TV watch football match
look首先它是强调看的动作 并且不及物 常见搭配 look at sth
let"s区别于 let us主要是反义疑问句
let"s ---shall we?
let us---will you?
至于网络上常见的us 或者"s是否包括说话者 没有任何一道考题会考 也并没有深究的意义
