三、容易混淆的形容词：
[考试说明] 熟练掌握形容词作定语、表语及宾语补足语的用法；熟练掌握表示时间、地点、方式、程度、原因等疑问副词的用法；熟练掌握形容词、副词比较等级的构成和good、well、many、much等不规则变化；掌握little、far、ill、bad、badly等不规则变化；能熟练运用下列句型表示两者(人或事物)和三者或三者以上(人或事物)的比较；初步掌握用much、little等副词在用法上的区别。
1. any & some
[误] have you got some money with you?
[正] have you got any money with you?
[误] would you like any milk?
[正] would you like some milk?
any和some意思是“一些”，用作定语，可修饰可数名词和不可数名词。any多用于否定句和疑问句，some多用于肯定句。
但如果说话人表示“请求，提议”或“希望得到肯定回答”的意义时，some也可用在疑问句中；some还可用于单数名词前，表示未知或说话人不想特别说明的人、地、物等，意思是“某一，某个”。
如果表示“任何，无论哪个”时，any可用在肯定句中。
2. either & each & both & neither & every
[误] there are many flowers on either side of the street.
[误] there are many flowers on neither side of the street.
[误] there are many flowers on each sides of the street.
[正] there are many flowers on both sides of the street.
[正] there are many flowers on each side of the street.
[误] every student has not finished their homework.
[正] no student has finished their homework.
either意思是“两者之一的”，each意思是“任意一个的”，neither意思是“两者都不的”，every强调整体，意思是“个个”。
3. few/little & a few /a little
[误] sorry, i have few money on me.
[正] sorry, i have little money on me.
[误] her books are few.
[正] she has few books.
[误] the work needs a few number of workers.
[正] the work needs a small number of workers.
[正] the work needs a few workers.
few后跟可数名词复数，little后跟不可数名词，都表示“几乎没有”的否定性意思；a few和a little区别也在于前者跟可数名词，后者跟不可数名词，都表示“有几个”的肯定性意思。
4. no & not
no意思是“没有”，可以否定一切名词，修饰不可数名词和可数名词的复数时等于not any，修饰可数名词单数时等于not a/an；如果被修饰的名词通常情况下只有一个，则用它的单数形式；不能用a、the、all、every等限制词之前，而not可以。
not意思是“不，不是”，可以否定一切动词，修饰动词。
no more than意思是“不过，仅仅”，相当于only，修饰“数量”词，强调“少”的含义；not more than意思是“至多，不多于，不超过”，用于陈述事实；no more…than和not more…than多用于多音节形容词的比较级。
5. already & yet & still
[误] when we arrived at the airport, the plane had taken off yet.
[正] when we arrived at the airport, the plane had taken off already.
[正] when we arrived at the airport, the plane had already taken off.
already意思是“已经”，一般用于肯定句，常与完成时连用，常用于句中；yet意思是“已经，还”，一般用于否定句和疑问句，常用于句末；still意思是“仍然，还是”，强调动作在进行，主要用于肯定句，常用于句中。
6. also & too & either & so & neither & nor
[误] my parents didn’t like swimming, nor did his.
[正] my parents didn’t like swimming, neither did his.
also用于肯定句，一般放在行为动词之前、助动词、情态动词、系动词之后，too一般用于肯定句末，前面常用逗号；either一般用于否定句末，前面也用逗号；so置于句首，引起句子倒装，表示前面所讲的情况也适用于另一个人或物，具有否定的意思；so后的主语与前一句主语是同一个人或物时，后面的主谓不倒装，表示“确实如此”；neither置于句首，引起句子倒装，表示前面所讲的情况不适用于另一个人或物，具有否定的意思；nor常与not连用，表示“也不”，neither和nor都可用来对前面的否定陈述加以补充，如果补充的成分否定的不是同一事物，同一内容，就只能用nor，不可用neither；当否定的并列分句有两个以上时，只能用nor，因为neither只能指两者中的一个，nor指三个以上的另一个。
7. sometimes & sometime & some time & some times
[误] you can only keep the book for sometime.
[正] you can only keep the book for some time.
sometimes是频度副词，意思是“有时，不时”，常与一般现在时或一般过去时连用；sometime是副词，意思是“在某个不确定的时间，在某个时候，某时”，可与将来时或过去时连用；some time是名词词组，意思是“一段时间”，做时间状语，也可用作副词词组，用来指一个未肯定的时刻，常指将来，此时可与sometime通用；some times是名词词组，意思是“几次，几倍”。
