In the following weeks, Stacy began to express daily   46  in coming to the stall with me. She   47  spent time with him, feeding, brushing and combing him, all the  48  talking to him about her life.
Then one day   49  I was readying one horse for a ride, I noticed the old guy’s   50 expression and desire to be included, too. So I asked Stacy if she wanted to take Twist out for a ride.

阅读下面这首诗,完成后面的题目。

我爱这土地


艾 青
假如我是一只鸟,
我也应该用嘶哑的喉咙歌唱:
这被暴风雨所打击着的土地,
这永远汹涌着我们的悲愤的河流,
这无止息地吹刮着的激怒的风,
和那来自林间的无比温柔的黎明……
——然后我死了,
连羽毛也腐烂在土地里面。
为什么我的眼里常含泪水
因为我对这土地爱得深沉……
一九三八年十一月十七
