容易混淆的形容词和副词
形容词用来修饰名词；副词用来修饰动词、形容词、其他副词或整个句子。
可是，有时形容词和副词容易混淆。例如“A fast train reached the destinationfast”中的第一个“fast”是形容词，第二个就是副词。
此外，有些词既能是形容词，也能是副词，有些词义不变，另些词义不同；有些形容词加上后缀“-ly”构成的副词和原来的形容词意思相近，但有一些意义则相差甚远；更有些形容词，除自己本身能兼而充当副词之外，又可以再加上后缀“-ly”构成派生副词，若不小心，容易引起混淆。
下面分别举例说明：
⑴可作形容词又可作副词，词义不同如：
①a. Joelle is a pretty child.（形容词）
b. Tom will be back prettysoon.（副词）
②a. The old man has been ill for sometime.（形容词）
b. Don't speak ill ofothers.（副词）
⑵既是形容词，也是副词，句子中的语法功能不同，但意义一样，如：
③a. What a deep ocean it is !（深的）
b. The boy dug deep into theground.（深）
④a. Look at the high mountain!（高的）
b. Birds fly high in thesky.（高）
⑶形容词可以充当副词，又可以加上后缀，构成派生副词。在某些场合，两者相近，可以通用（如例⑤和⑥）；在另一些场合里，两者意思有异，不可混为一谈（如例⑦和⑧）：
⑤a. Hold it tight, please!
b. Hold it tightly,please!
⑥a. Please read slower.
b. Please read moreslowly.
⑦a. John came late yesterday.（迟）
b. John has been working hardlately.（最近）
⑧a. Jason works hard.（努力地）
b. Susan hardlyworks.（几乎不）
⑷有些形容词或副词，同时有多个意思，如：
⑨a. Hard labour（苦工）
b. Hard times（艰难时代）
⑩a. The baby is fast asleep.（睡得熟）
b. Run fast, please!（请快跑）
c. Hold the ropefast!（紧握绳索）
⑸同词根的派生形容词和形容词及分词间，意思虽甚接近，但容易引起混乱，如：
11a. The child is sleepy.（昏昏欲睡）
b. The child is stillasleep.（还在睡眠中）
c. Why are you looking at thesleeping child?（睡着的）
12a. Diana feels lonely/ lonesome in the bighouse.（感到寂寞）
b. Mary was alone in theoffice last night.（独自）
13a. Irene was awake the whole night lastnight.（整夜未眠）
b. Tom had a wakeful nightlast night.（整夜未眠）
c. What did you do during yourwaking hours last night?（醒着的时刻）
(a)和(b)意思相近，但(a)的 awake只能作补足语；(b)的 wakeful 则没有这个局限。(c)里的waking现在分词和(a)及(b)的两个形容词也似同非同，不易随意取代。
在英语中,某些形容词词形同时也可作副词,但这些形容词还有加后缀-ly副词的形式,因此这类词就有两种副词形式，它们在用法上有些可以互换， 有些是有区别，下面笔者对这类词做一总结。
一般地说，可以互换的这类词，形容词词形的副词表示比较具体的概念，经常用语口语中，不太正式；后缀-ly形式的副词，表示比较抽象的概念，有引申义，并有一定感情色彩，变副词比较级时，用此类副词，如修饰动词和分词，放在它们前面。
