在英语中,spend,cost,take,pay都有\"花费\"之意.但它们是有区别的.
spend的主语必须是\"人\",宾语可以是钱、精力、时间等.其后用on+名词或用in(可省略)+动名词形式.它是在表示\"某人买东西花多少钱\"时使用.如:
She spends too much money on clothes.她在服装上面花费太多的钱.
He spends half an hour playing football every day.他每天踢半小时足球.
cost的主语必须是\"物\"或\"事\",表示\"费用\"、\"耗费\".它是在表示\"东西的价值、价格\"时使用.如:
The dictionary cost me fifty yuan.这本字典花了我50元钱.
How much does this ruler cost?这把尺子多少钱?
take表示\"花费\"时,主语一般是\"一件事\".如:
It took me half an hour to do housework.做家务花去我半小时时间.
It takes a lot of money to buy the house.买这座房子要花很多钱.
pay的基本意思是\"支付\",作为及物动词,宾语可以是\"人\"、\"钱\".如:
He paid the taxi and hurried to the station.他付了出租车的钱,匆忙向车站赶去.
We had to pay 200 franc.我们得付二百法郎.
I\'ll pay you in a few days.几天后我付给你钱.
