Rex soon became an expert at opening the gate. 雷克斯很快成了开门的专家。
（2）hold one's breath 为固定短语，表示"屏住呼吸"：

not long before 通常译为"不久"、"很快"。 so…that 引导的是结果状语从句。 pick up 表示"捡起"。weight 在这里指比重较大（因此能沉在水底）的物品。 be accustomed to 表示"习惯的"、"适应了的"，后面通常跟名词或动名词：

Line these chairs up, please. 请把这些椅子排好。 5．Whether they will ever become future Olympic champions, only time will tell. 他们将来是否能成为奥林匹克的冠军，这只能由时间来作出回答。
这是一个倒装句，宾语从句置于句首。通常，以疑问词引导的宾语从句会用于这种句型：
What made him do it, no one knows. 是什么使得他干了这事，没有人知道。
