首先,应掌握它的三个词性:动词,名词,形容词。
1. 动词。基本用法:
(1) exchange sth 即“交换某物”。例:exchange gifts(交换礼物); exchange ideas(交换想法)
(2) exchange A for B 即 “用A来换B”。例:exchange dollars for RMB(美元换人民币); exchanging labor for room and board(用劳动来换取食宿); exchange a position in the private sector for a post in government(用私营部门的职位换取政府机构的岗位)。
2. 名词。基本用法:
(1) “交换,互换”。例:There have been numerous exchanges of views between the two governments(两国政府间曾多次交换意见。).
(2) “兑换,汇率”。例:The purpose was to halt the rise in the exchange rate of the Swiss franc(目的在于制止瑞士法郎汇率上涨。).
3. 形容词。基本用法:
“交换的,交流的”。例:an exchange student(交换生); exchange programs (交流项目)
所以不是exchange的后面一定要加for,要看你是否有交换的目的,因些那两句中并不需要for。
