exchange既可用作不及物动词,也可用作及物动词。用作及物动词时,接名词或代词作宾语,且所接的名词一般为复数。exchange宾语后常接介词for,表示“以…换取”; 接介词with表示“与某人交换(某物)”。exchange后一般接复数名词,但如果该名词是行为名词,也可用其单数。
exchange的用法
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。
Any beautiful backpack can't even exchange my little bag.
The most beautiful bag also can't exchange my satchel.
