【答案与解析】
【文章大意】短文介绍了游泳时需要注意的一些安全常识。第一，只能在适合游泳的地方游泳，不要去陌生水域游泳。第二，头朝下潜水时一定在深水区，否则会伤害到自己。第三，不要独自一人去游泳，遇到危险会有人相救。第四，关注儿童游泳安全问题。儿童学游泳要用家人相伴，家庭游泳池周围要有护栏。
14．C  句意：但是游泳也有危险。根据后面的句子“so it’s important to stay safe as you do it.”可知，游泳的时候安全是非常重要的。因此前一句说游泳也会有危险，故答案为C。
15．E  句意：否则你的头会撞到底部。根据前面的句子“In natural water, don’t dive unless you know that the water is deep enough.”可知，在自然水域，在你不知道水深时不要潜水。此句是说如果这样做了会产生的后果，故答案为E。
16．D  句意：几秒钟的时间就会产生重大作用。本段主要强调游泳时确保有一个搭档，遇到危险及时向搭档求救，在这种危险的时刻，几秒钟的时间也很重要，对生与死也会产生巨大的影响，故答案为D。
17．B  句意：所以成年人应该一直在现场。根据前面的句子“Kids who don’t know how to swim should wear life jackets. But by themselves they are not enough,”不会游泳的孩子应该穿救生衣。但如果是他们自己游泳，救生衣是远远不够的，因此本句是强调在孩子学习游泳时，需要大人时刻在身边保护，故答案为B。
