C. what to work D. how to work

Answer 1

D

【解析】

試題分析：句意：我不擅長數(shù)學(xué)，因此我不知道怎樣做出這道數(shù)學(xué)難題。when to work什么時候做出；who to work誰做出；what to work做出什么；how to work怎樣做出。根據(jù)句意可知選D。

考點：考查疑問詞加動詞不定式。

考點分析： 考點1：不定代詞

   不定代詞指不是指明代替任何特定名詞的代詞。常見的不定代詞有a11，both，each，every等，以及含有some-，any-，no-等的合成代詞，如anybody， something，no one。這些不定代詞大都可以代替名詞和形容詞，在句中作主語、賓語、表語和定語， 但none和由some，any，no等構(gòu)成的復(fù)合不定代詞只能作主語、賓語或表語；every和no只能作定語。如：  --- Do you have a car? --你有一輛小汽車嗎？  --- Yes，I have one. --是的，我有一輛。  --- I don’t know any of them. 他們，我一個也不認(rèn)識。

   不是指明代替任何特定名詞的代詞叫做不定代詞，在句中可作主語、表 語、賓語和定語。現(xiàn)將幾個常用的不定代詞舉例說明如下： 
1. some與any的區(qū)別 
1）some多用于肯定句，表示“一些，幾個”作形容詞時，后面可以接
①不可數(shù)名詞+單數(shù)動詞；
②可數(shù)名詞+復(fù)數(shù)動詞。 
Look! Some of the students are cleaning the library.     . Some rice in the bag has been sold out.    
2）any多用于疑問句、條件句和否定句中，表示“一些，任何”用作形容詞
時，后面可以接
①不可數(shù)名詞+單數(shù)動詞；
②可數(shù)名詞+復(fù)數(shù)動詞。      
If you have any questions, please ask me.      There isn't any orange in the bottle.      Have you got any tea?      
3）any和some也可以作代詞用，表示“一些”。any多用于疑問句或否定
句中，some多用于肯定句中。      How many people can you see in the picture?      I can't see any.
     If you have no money, I'll lend you some. 
  注意：與some, any結(jié)合的詞如something, somebody, someone, 
anything, anyone, anybody在肯定句、否定句、疑問句、條件句中的用法，大致和some, any的用法相同。 
2. few, a few, little, a little在用法上的區(qū)別 
1）用作形容詞： 
   含義 用法 
表示肯定 表示否定 用于可數(shù)名詞 a few雖少，但有幾個 few不多，幾乎沒有 
用于不可數(shù)名詞 a little，雖少，但有一點 little不多，沒有什么   I'm going to buy a few apples.   He can speak only a little Chinese.   There is only a little milk in the glass.   He has few friends. 
  They had little money with them.   
2）a little和little也可以用作副詞，a little表示“有點，稍微”，little表示“很少”。 
  I'm a little hungry. (修飾形容詞hungry)   Let him sleep a little. (修飾動詞sleep) 
  Mary, go a little faster, please. (修飾副詞比較級)   She slept very little last night. 
3. other, the other, another, others, the others的區(qū)別。 用  法

1）other可以作形容詞用，后面可以跟單數(shù)或復(fù)數(shù)名詞，意思是“其他的、別 的”。   Where are his other books? 
  I haven't any other books except this one. 
  
2）other也可以用作代詞，與冠詞the連用構(gòu)成“the other”，表示兩個人或物中的“另一個”。常與one搭配構(gòu)成“one ..., the other ...”句型。 
  He has two brothers. One is 10 years old , the other is 5 years old.   She held a ruler in one hand and an exercise-book in the other. 
  
3）other作代詞用時，可以有復(fù)數(shù)“others”，泛指“另外的人或物”。常與some搭配構(gòu)成“some ...., others ...”句型。

毫無例外 
4)用于兩者或兩者以上中的每一個人或物 4)用于三者或三者以上每一個人或物   The teacher gave a toy to each child.   Each ball has a different colour.    當(dāng)我們說each child, each student或each teacher時，我們想到的是一個人的情況。而當(dāng)我們說every child和every student時，我們想到的是全體的情況，every的意思與all接近，表示他們都如此。 
  Every student loves the English teacher. = All students love the English teacher. 
Every child likes playing. = All children like playing. 
5. all和both的用法。
1）all指三者以上，或不可數(shù)的東西。謂語動詞既可以用單數(shù)，也可以用作復(fù)數(shù)。在句中作主語、表語、賓語、同位語和定語。   All of us like Mr Pope. 我們都喜歡Pope先生。（作主語）   = We all like Mr Pope. (作同位語)
