三 旁边的同学看到他们的海报，也来帮忙出主意。选择正确的选项补全句子。

()5. The little girl is standing her mother near the pool.
A. by B. on C. in

1. B 【解析】在马路上踢足球很危险，所以这里表示“不应该”。shouldn't 意为“不应该”，所以选B。
2. C 【解析】句意为：你看起来冷。你想出门前应该热身。should 意为“应该”，所以选C。
3. B 【解析】others 意为“其他人”，符合语境。other 后面通常要跟名词，不能单独用。the other 表示“（两个中的）另一个”，句子里没有“两个”的范围。所以选B。
4. C 【解析】be careful 是固定搭配，意为“小心”。句首用 Be，所以选C。
5. A 【解析】句意为：小女孩站在妈妈旁边，靠近池子。by 意为“在……旁边”。所以选A。
