⒃ too...to... 与 so...that... 的问题：副词 too/so 后面跟形容词或副词, to 后面跟动词, that 后面跟从句。 Too...to... (“太.……以致不……”)是否定的结构,用于简单句； so...that... (“如此…以致…”)是肯定结构,用于复合句。如：

⒆ rather 与 quite 的用法区别：同 very 一样,两个词都表示形容词或副词的程度, quite 表示“不到最高程度但是比预料的好”, rather 比 quite 更接近 very 的含义,含有令人惊讶的意思。见下图对“ nice ”程度的描绘：
(小) not nice →(fairly) nice →quite nice →rather nice →very nice（大）
如：It’s quite a nice film .(这是部好片子)。(可能意味着不是一部最好的电影)
It’s rather a nice film .(这是部很不错的电影。)(意味着比大多数电影都好)
[注意]注意quite与rather后面的词序。
⒇ maybe、possibly、perhaps 的区别： maybe “可能、也许”,比另外两个词更不正式、更随便、可能性不大； possibly “可能地、或者、也许”,可能性较大,在否定句和疑问句中表示“无论如何”； perhaps “可能”,较为常用而且正式,可能性也不大。如：
You could put it over there,maybe.(也许你可以把它放在那边)
I couldn’t possibly have finished such a long book in such a short time.(我不可能在这么短的时间内完成这么长的一本书)

(21) most、mostly 的区别： most 作为形容词和名词时意思是“大多数的、大部分的”,作为副词时意思为“最,十分、很”； mostly 仅为副词,意思为“主要地、多半地、大部分地”。如：I was at home most of the time when I was free.(我有空时大部分时间都在家)
Most children are naughty.(大部分的孩子都淘气)
This is the most exciting part of the film.(这是电影中最令人兴奋的部分)
She is mostly out on Sundays.(星期天她一般不在家)
(22) (be) worth、(be) worthy of 的区别： worth 一般被看作是介词,后面接名词或者动名词,用主动表示被动含义,还可以用副词 well 修饰； worthy of 表示“值得的、配得上的”,后面跟动名词的被动形式。如：
What is worth doing at all is worth doing well(凡是值得做的,就值得好好去做).
The house is worth ￥300,000.(房子价值30万元)
This book is well worth reading several times.(这本书值得好好读几遍)
It is a thing worthy of being seen.(这是一个值得看的东西)
(23) almost、nearly 的区别：两个词意思相近,都表示“几乎、将近”,大多数情况下可以互换,与否定词连用时用 almost 不用 nearly . almost no 相当于 hardly any (几乎没有)。如：
He had done almost nothing today.(他今天几乎没有干什么)
We are almost/nearly there.(我们几乎就到那里了)
Almost nobody/Hardly anybody understood his words.(几乎没有人懂他的话)
(24) a bit 与 a little 的区别：这两个名词短语经常当作副词使用,修饰形容词或副词的原级或比较级,可以互换,语气比 rather 弱。如：
This digital camera is a bit(a little) expensive.(这台数码相机有点贵)
It is a little(a bit) colder than yesterday.(今天比昨天冷了点)
另外, a little 可以直接加不可数名词, a bit 则采用“ a bit + of +名词(不可数或可数名词复数)”的形式。如：
I have got a bit of a cold.(我有点感冒)
Go and get a little water for me, please.(请你去给我搞点水来)
[注意] not a bit (= not at all )意为“根本不”,而 not a little 则意为“非常,不是一点”。
