exchange既可用作不及物動(dòng)詞,也可用作及物動(dòng)詞。用作及物動(dòng)詞時(shí),接名詞或代詞作賓語(yǔ),且所接的名詞一般為復(fù)數(shù)。exchange賓語(yǔ)后常接介詞for,表示“以…換取”; 接介詞with表示“與某人交換(某物)”。exchange后一般接復(fù)數(shù)名詞,但如果該名詞是行為名詞,也可用其單數(shù)。

首先，應(yīng)掌握它的三個(gè)詞性：動(dòng)詞，名詞，形容詞。

1. 動(dòng)詞。基本用法：

(1) exchange sth 即“交換某物”。例：exchange gifts（交換禮物）; exchange ideas（交換想法）

(2) exchange A for B 即 “用A來(lái)?yè)QB”。例：exchange dollars for RMB（美元換人民幣）; exchanging labor for room and board（用勞動(dòng)來(lái)?yè)Q取食宿）; exchange a position in the private sector for a post in government（用私營(yíng)部門(mén)的職位換取政府機(jī)構(gòu)的崗位）。

2. 名詞。基本用法：

(1) “交換，互換”。例：There have been numerous exchanges of views between the two governments（兩國(guó)政府間曾多次交換意見(jiàn)。）.

(2) “兌換，匯率”。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匯率上漲。）.

3. 形容詞。基本用法：

“交換的，交流的”。例：an exchange student（交換生）; exchange programs （交流項(xiàng)目）

所以不是exchange的后面一定要加for，要看你是否有交換的目的，因些那兩句中并不需要for。

Any beautiful backpack can't even exchange my little bag.

3. They exchange traveller's cheques at a different rate from notes.
