瞬间秒杀听力 第518期:海中游泳须知（在线收听）

Swimming in the ocean

can be a dangerous activity, especially

when you aren't comfortable in the water.

The ocean is strong

and the direction of the water

can change at any moment.

The best way to keep yourself safe

is to make sure that you are a strong swimmer.

Practicing in a local swimming pool

is the best way to improve your strength.

It is also a good idea

never to go in the ocean alone

if you are not a strong swimmer.

Even though the ocean may look cool

and refreshing on a hot summer day,

it is full of dangers

that you should be aware of at all times.

在大海里游泳可能是一项危险的活动，

特别是当你在水中感到不适的时候。

海洋中的水流很强，而且方向随时都可能会改变。

确保自己安全的最佳方法

就是确定自己是一个游泳健将。

在当地附近的游泳池内练习

是增进耐力的最佳方式。

如果你不是个游泳健将，

千万不要独自下海游泳。

即使在炎炎夏日海洋

看起来凉爽又令人心旷神怡，

但它却是一个危机重重，

须让人随时提高警觉的地方。
