疑问代词在句中应位于谓语动词之前,没有词性和数的变化,除who之外也没有格的变化。 
what, which, whose还可作限定词。
Whose books are these on the desk?
桌上的书是谁的?
What was the directional flow of U. S. territorial expansion?
美国的领土扩张是朝哪个方向的?
What events led to most of the east of the Mississippi River becoming part of the United States?
哪些事件使密西西比河以东的大部分土地归属于美国?
疑问代词在句中起名词词组的作用,用来构成疑问句。疑问代词有下列几个:
指 人: who, whom, whose
指 物: what
既可指人又可指物: which

  • 疑问代词说明:
    一、无论是做疑问代词还是限定词,which 和 what 所指的范围不同。what所指的范围是无限的,而which则指在一定的范围内,例如:
    Which girls do you like best?
    你喜欢哪几个姑娘?
    What girls do you like best?
    你喜欢什么样的姑娘?

    二、Whom是who的宾格,在书面语中,它作动词宾语或介词宾语,在口语中作宾语时,可用who代替,但在介词后只能用whom, 例如:
    Who(m) did you meet on the street?
    你在街上遇到了谁?(作动词宾语)
    Who(m) are you taking the book to?
    你要把这书带给谁?(作介词宾语,置句首)
    To whom did you speak on the campus?
    你在校园里和谁讲话了?(作介词宾语,置介词 后,不能用who取代。)

    三、疑问代词用于对介词宾语提问时,过去的文体中介词和疑问代词通常一起放在句首,现代英语中,疑问代词在句首,介词在句未,例如:
    For what do most people live and work?大部分人生活和工作的目的是什么?(旧文体)
    What are you looking for?你在找什么?(现代英语)

    四、疑问代词还可引导名词性从句,例如:
    I can't make out what he is driving at.
    我不知道他用意何在。
    Can you tell me whose is the blue shirt on the bed?
    你能告诉我床上的蓝衬衣是谁的吗?
    Much of what you say I agree with, but I cannot go all the way with you.
    你说的我大部分同意,但并不完全赞同。

  • 疑问代词用法:
    1. 疑问代词有who, whom, whose, which和what, 都是用来构成疑问句的:
    Who is calling? 谁打电话来?
    Whom do you want to speak to? 你想找谁接电话?
    作主语时用who,作宾语时用whom,在口语中用who作宾语时也不少:
    Who did you mean? 你指的是谁?
    Who are you talking about? 你们在讲谁?
    直接跟在介词后时只能用whom:
    With whom did you come? 你和谁一道来的?
    (口语中说“Who did you come with?时更多一些。)

    2. 其他三个疑问代词可用作:
    1)主语:
    What’s your address? 你的地址怎样写?
    Whose is better? 谁的好一些?
    Which of these is yours? 哪一本是你的?
    2)宾语:
    What do you mean? 你是什么意思?
    Which do you like better? 哪一个你更喜欢一些?
    Whose have you chosen? 你选了谁的?
    3)表语:
    What’s her name? 她叫什么名字?
    Whose is it? 这是谁的?
    4)定语(这样用时有些字典标作形容词):
    What time does the train leave? 这列火车什么时候离开?
    Which room shall we stay in? 我们住哪间房?
    Whose passport is this? 这是谁的护照?

    • 形容词的位置:
      1.形容词一般放在名词前作定语?  
      单个形容词修饰名词时,一般要放在名词的前面。它们的前面常常带有冠词、形容词性物主代词、指示代词、数词等。例如:?  
      a red flower一朵红花?
      an interesting story一个有趣的故事?  
      six blind men 六个盲人?
      my own house我自己的房子?
      如果有两个或两个以上的形容词修饰一个名词时,则由它们和被修饰的名词之间的密切程度而定,越密切的形容词越靠近名词。
      如果几个形容词的密切程度差不多则按音节少的形容词放在前面,音节多的形容词放在后面。  
      2.当形容词所修饰的词是由some,any,every,no等构成的不定代词时,形容词必须置于名词之后。例如:?  
          She has something new to tell me.?她有一些新的情况告诉我。?  
          I have nothing important to do today.?今天我没有重要的工作要做。?  
          Do you know anybody else here??这儿你还有认识的人吗??  
      3.形容词后面有介词短语或不定式短语时,形容词必须置于名词之后。例如:?  
          It is a problem difficult to work out.?这是一道难以解决的问题。?  
          Edison is a student difficult to teach.?爱迪生是个很难教的学生。?  
          This is a kind of flowers easy to grow.?这是一种易栽的花。?
