Question

David’sister often        her pocket money on books and magazines．

A. takes    B. pays    C. costs    D. spends

Answer

D

【解析】句意：大卫的妹妹经常把零花钱花在买书和杂志上。短语spend time／money on sth表示花钱买……；It takes sb. some time to do sth.表示花费时间做某事；pay for表示花费，主语是人；cost是物作主语；根据题意，故选D。

点睛：1)spend 主语是人，在……上花费时间(金钱) （spend- spent-spent）① sb. spend 钱/时间 on sth. eg :I spent two hours on this maths problem.

② sb. spend 钱/时间 (in) doing sth.

eg : They spent two years (in) building this bridge.

(2)pay….for 主语是人 付钱买……（ pay-paid-paid ）

①sb pay + 钱 +for sth. eg : I have to pay 20 pounds for this room each month.

②pay for sth. 付……的钱 eg : I have to pay for the book lost.

(3)take，用it 作主语，后面常跟双宾语，表示花费时间、金钱等；（take-took-taken） It takes sb. +时间+to do sth. 做某事花了某人多少时间 eg: It took them three years to build this road. 其中it是形式主语，真正主语是后面的动词不定式。 若对本句型结构中的some time提问，使用how long。 eg: It takes me an hour to do my homework every evening. How long does it take you to do your homework?

(4)cost 主语是物，表示某物值多少钱或花费某人多少钱（cost- cost- cost）

① sth. cost (sb.宾格)+ 钱

eg: A new computer costs ( me ) a lot of money.

It cost sixty yuan. How much does this watch cost?
