      九年级英语考前复习之如何辨析词汇

      1. think/ think/about/ think of

      (1) think 单独使用时表示"思考", 接that 宾语从句时意为"认为","觉得"。

      I am thinking how to work out the problem.

      I think she is a good student.

      当宾语从句含有否定概念时,通常形式上否定think ,但意义上却是否定宾语从句。

      I don't think he can come.

      I don't think it will be windy.

      (2)think about 可接一个名词,动词-ing 形式或由疑问词引导的不定式或宾语从句,意思是"考虑……"。

      I have thought about it for a long time.

      Please think about how to tell her the bad news.

      (3)think of 表示"认为", 一般用于疑问句中,与what 连用。

      What do you think of the TV play? = How do you like the TV play?

      2. big/ large/ great

      上述形容词都表示"大",但侧重点及程度不同。

      (1) big指具体事物的大小,强调比正常形体的标准大,既可用在普通场合,也可用在正式场合。它可用来指人的身材高大或"长大了",还可表示"伟大","重要"之意。如:

      Can you lift up this big stone?

      On the last day I made a big decision.

      (2) large特别强调远远超过标准的大,指体积、面积、容积、数量之大。如:

      A whale is a large animal.

      A large crowd collected at the gate of the theatre.

      (3) great除了表示数量体积之大外,又指抽象的程度,意味着伟大性,重要性,优越性;常用于抽象

      或无形的东西;用于有形的东西时,常带有"伟大","大得令人吃惊"等意思,含有一定的感情色彩。如:

      China is a great country with a long history.

      He was one of the greatest scientists.

      3. cost/ take/ spend/ pay

      (1) cost表示"花钱",花费,付出(只能用于钱、精力、生命等;主语必须是物。)

      The book cost me five yuan.

      (2) take的主语是动词不定式, 通常用it做形式主语。

      It took me five yuan to buy the book...

      (3) spend,在主动语句中主语是人

      I spent five yuan on (for) the book.或I spent five yuan (in) buying the book.

      (4) pay的主语是人。

      I paid five yuan for the book.

      4. expensive/ high/ cheap/ low

      这四个词在谈论到价格的高低时,要注意使用。expensive与high涉及到价格"高",而cheap 与low涉及到价格"低"。

      (1) expensive昂贵的,花钱多的。这个单词若谈到"价格高,货贵"时,其主语不能是价格,必须是货物、物品本身。如:

      This watch is expensive. 这只表很贵。

      These glass-products are not expensive. 这些玻璃制品不是很值钱。

      注意:cheap表示"价廉","便宜的",其主语也不能是价格,必须是物品本身。如:

      The cheap table was bought from him. 这张便宜的桌子是他卖给我们的。

      This cloth doll is very cheap. 这只布娃娃很便宜。

      (2)high在表示价格时,含义是"高",low在表示价格时,含义是"低",这两个词不能用于物品本身,只能用在价格上。如:

      The price of this watch is very high. 这只表的价格太高了。

      The price of this book is not low for me. 这本书的价格对我来说是不低。

      下面我们试看几个句子的正误对照

      The price of this computer is expensive.

      (宜改为:This computer is expensive. 或The price of this computer is high. )

      The price of this pen is not cheap for him to buy.

      (宜改为:This pen is not cheap for him to buy. 或 The price of this pen is not low for him. )
