Answer 1

小品词词类判断
什么叫小品词?
小品词就是副、介同形的单词,由于在句中的作用不同,词性也就不同.在没有搞清是介词,还是副词的时候,就称之为“小品词”.
【理解要领】
※介词、副词形一样,句中作用不相同,介词后面要宾语,副词后面宾不用.
※介词要和动一起,副词可与动分开；及物动词加副词；不及物动词加介词,加了介词相当于及物动词.
1. 常用介、副同形的单词有：
in
on
up
down
off
out
over
along
by
through
across
round
across
round
near
before
behind
past
since
under
最难区别的几个小品词：
in
on
up
out
off
down
over
through
along
by

2. 介词、副词的区别方法：
【判别方法】
　He got off the bus /at the corner．（按照意群来划分,bus是off的宾语,所以这里的off是介词）
　　他在拐角处下了公共汽车.
　He get off /at the corner．（按照意群来划分,off后面没有词,所以这里的off是副词）
　　他在拐角处下车.
I found him in. (in后没有名词,它就是副词.)
我发现他在里面.
I found him /in the room. （按照意群来划分,in是和the room联系在一起构成介词短语的,所以它是介词.）
我发现他在室内.

3. 副词的不同使用方法
【副词使用方法】
这种副词两边分,有的跟动词联系紧；有的句末单独行.
可跟动词一起构成短语动词的副词
in
on
up
down
off
out
over
along
by
through
across
round



只能放在句末使用的副词
before
behind
past
since
under
near

1.2）不及物动词＋介词＝及物动词

注解
listen to
听
He is listening to a radio now.他在听收音机.
listen不能直接接听的对象,加to就可以了
look for
寻找
She is looking for her pencil now.她在寻找她的铅笔.
look是看的意思,加了for就是新的词义“寻找”
look after
照看
My mother looks after my baby.我母亲照看孩子
look 后面的介词不同,词义就不同,但与look有关,
hear from
收到来信（等）

hear from 成了固定的词义,表示受到来信,信函等
hear of
听到,得知

hear of是听别人谈到过的意思
read of
读到
I have read of Lu Xun. 我读过关于鲁迅的书籍.
read of不是直接读鲁迅,而是读到过关于鲁迅的资料或书籍

laugh at 可以带宾语,而且表示嘲笑,嘲弄的意思
run after

run后加after,主要是追赶某人或某种时尚：run当及物动词用,通常是管理或经营的含义

What does “PTO” stand for? “PTO”代表什么?
stand for 一起使用,就相当于一个新词,表示：代表,象征的含义

5. 学习和考试注意事项
【重点学习内容】
主要学会：
1. 不及物动词后加适当介词可以构成相当于及物动词的动词短语：
Wait for sb.就是典型的例子：
常有人说 I will wait you here. 还不知道错了.应该说成 I will wait for you here.因为wait 是不及物动词,不能带宾语.
类似的还有：
look at look for look after , listen to 等等,并且注意类似于： read of 和hear of 这样的短语的区别.
2. 介词后面的名词,或者相当于名词的词就是介词宾语,既然是宾语就要用宾格,特别要注意的代词宾格.
He is looking at me.
She is looking after her sister.
We waited for him for a long time.
I heard of him before.
3. 同一动词后加不同介词/副词就会有不同的含义,要当作一个新词来记:
look at
look about
look ahead
look around
look as if
look away
look back
look down upon
look for
look forward to
look in
look down
look into
look like
look on /look upon
look up to
look on with
look out
look out ofr
look over
look round
look through
look to
look to be


4. 及物动词带有副词后接宾语与不及物动词后接介词再加宾语是不同的.
1） 不及物动词后接宾语时,动词和介词是不可分开的,两者成为一个整体.
2） 及物动词后接副词,该副词可以和动词分开,特别是宾语为代词宾格的时候,这个代词就要放在动词和副词之间.
He is always looking for his shoes. (不能分开)
He always forgets to turn the lights off. He always forgets to turn off the lights.
He always forgets to turn them off. （这个句子中的them指的是等,不能放在off的后面,因为它是代词宾格）
