八、从括号中选择正确的单词填空。
1. We should swim in the
(swimming swim) pool.
2. It’s not
(safe safety) for you to jump from the stairs.
3. We shouldn’t
(sitting sit) down right now.
4. The little girl cries because her arm
(hurt hurts).
5.
(Keep To keep) safe on the road, we should wait for the green traffic light.
答案：1. swimming
2. safe
3. sit
4. hurts
5. To keep
解析：
1. 本题考查固定搭配，swimming pool是固定常用短语，意为“游泳池”，因此选swimming。
2. 本题考查固定句型"It's + 形容词 + for sb to do sth"，意为“对某人来说做某事是……的”，此处需要填入形容词，safe是形容词意为“安全的”，safety是名词意为“安全”，因此选safe。
3. 本题考查情态动词的用法，情态动词shouldn't后面必须接动词原形，因此选sit。
4. 本题考查一般现在时的谓语变化，主语her arm是第三人称单数，对应的谓语动词要使用第三人称单数形式，因此选hurts。
5. 本题考查不定式作目的状语的用法，此处表达“为了在路上保证安全”的含义，用To keep表目的，因此选To keep。
