1.1.

A save

B share

C use

D donate

解析：选C。C 考查动词辨析。从后面的“she had left before payday”可以得知她考虑是否“用（use）”身上所有的钱给孩子买纸尿裤。该题容易误选B，认为Rueda是把自己的钱“分享（share）”出去，然而此时的Rueda是一个没有钱的人，根本不可能把自己的钱分享给其他人。故选C。

2.2.

A stood

3.3.

A peace

B balance

C charge

D patience

解析：选D。D 考查名词辨析。从后面的“and was screaming and crying for us to leave”可以得知，孩子在喊叫，说明孩子失去了继续呆在那里的“耐心（patience）”。故选D。
