九年級英語考前復(fù)習(xí)之如何辨析詞匯
1. think/ think/about/ think of
(1) think 單獨(dú)使用時表示"思考"， 接that 賓語從句時意為"認(rèn)為"，"覺得"。
I am thinking how to work out the problem.
I think she is a good student.
當(dāng)賓語從句含有否定概念時，通常形式上否定think ，但意義上卻是否定賓語從句。
I don't think he can come.
I don't think it will be windy.
(2)think about 可接一個名詞，動詞-ing 形式或由疑問詞引導(dǎo)的不定式或賓語從句，意思是"考慮……"。
I have thought about it for a long time.
Please think about how to tell her the bad news.
(3)think of 表示"認(rèn)為"， 一般用于疑問句中，與what 連用。
What do you think of the TV play? = How do you like the TV play?
2. big/ large/ great
上述形容詞都表示"大"，但側(cè)重點(diǎn)及程度不同。
(1) big指具體事物的大小，強(qiáng)調(diào)比正常形體的標(biāo)準(zhǔn)大，既可用在普通場合，也可用在正式場合。它可用來指人的身材高大或"長大了"，還可表示"偉大"，"重要"之意。如：
Can you lift up this big stone?
On the last day I made a big decision.
(2) large特別強(qiáng)調(diào)遠(yuǎn)遠(yuǎn)超過標(biāo)準(zhǔn)的大，指體積、面積、容積、數(shù)量之大。如：
A whale is a large animal.
A large crowd collected at the gate of the theatre.
(3) great除了表示數(shù)量體積之大外，又指抽象的程度，意味著偉大性，重要性，優(yōu)越性;常用于抽象
或無形的東西;用于有形的東西時，常帶有"偉大"，"大得令人吃驚"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"花錢"，花費(fèi)，付出(只能用于錢、精力、生命等;主語必須是物。)
The book cost me five yuan.
(2) take的主語是動詞不定式, 通常用it做形式主語。
It took me five yuan to buy the book...
(3) spend，在主動語句中主語是人
I spent five yuan on (for) the book.或I spent five yuan (in) buying the book.
(4) pay的主語是人。
I paid five yuan for the book.
4. expensive/ high/ cheap/ low
這四個詞在談?wù)摰絻r格的高低時，要注意使用。expensive與high涉及到價格"高"，而cheap 與low涉及到價格"低"。
(1) expensive昂貴的，花錢多的。這個單詞若談到"價格高，貨貴"時，其主語不能是價格，必須是貨物、物品本身。如：
This watch is expensive. 這只表很貴。
These glass-products are not expensive. 這些玻璃制品不是很值錢。
注意：cheap表示"價廉"，"便宜的"，其主語也不能是價格，必須是物品本身。如：
The cheap table was bought from him. 這張便宜的桌子是他賣給我們的。
This cloth doll is very cheap. 這只布娃娃很便宜。
(2)high在表示價格時，含義是"高"，low在表示價格時，含義是"低"，這兩個詞不能用于物品本身，只能用在價格上。如：
The price of this watch is very high. 這只表的價格太高了。
The price of this book is not low for me. 這本書的價格對我來說是不低。
下面我們試看幾個句子的正誤對照：
The price of this computer is expensive.
(宜改為：This computer is expensive. 或The price of this computer is high. )
The price of this pen is not cheap for him to buy.
(宜改為：This pen is not cheap for him to buy. 或 The price of this pen is not low for him. )
