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. )
