spend的基本句式:
spend…on sth
spend…in doing sth
老师说有时用: spend…on doing sth
请问:spend…in doing sth与spend…on doing sth有何区别?
黎老师:
▲spend…in doing sth与spend…on doing sth都可以表示“花费金钱做某事”,通常可以互换使用。例如:
He spends a lot of money on entertaining friends. (张道真主编《现代英语用法词典》p.1455)
He spends his whole life in looking after the poor. ( 同上,p.1456)
▲表示“花费时间做某事”时,spend…in doing sth 和 spend…on sth 在语义上有所区别。例如:
He spent half a year on writing a short play. 他把半年工夫花费在写 一个短剧上。
He spent half a year in writing a short play. 他费了半年写 一个短剧。
