解析：本文叙述了作者第一次去上游泳课，起初很害怕，后来在老师的指导下，有了自信，在下课前作者能够在水中漂浮大约一分钟的时间。最后指出作者对于游泳变得很感兴趣了。
【小题1】考查固定短语。这是固定短语all the time一直，始终。
【小题2】考查代词。因为made sure 后是宾语从句，这里缺少从句的主语，根据上文I became more confident可知应是I.
【小题3】考查连词。这里是made sure 后有两个宾语从句，第一个that可以省略，and后的第二个that不能省略，故用that.
【小题4】考查固定短语。at least至少。
【小题5】考查连词。and表示前后是并列关系。
