课文预读
崭新的生活空间
［第1～2段译文］
1月19日
我坐在温暖的夜空下，手里拿着一瓶冷饮,回忆着当天的事情——这纯粹是神奇的一天！这天上午，我戴着呼吸器在近海的珊瑚礁上潜泳，这是我从来没有过的绝妙经历。

看到这样奇特的美景,我周身的每个细胞都苏醒了,就像发现了一个全新的生活空间似的。

我首先注意到的是我周围那些鲜艳的色彩——紫色、红色、橘黄、明黄、蓝色和绿色。

那些珊瑚都是稀奇古怪的——有的形状像扇子、盘子、脑袋和彩带，有的像蘑菇、树枝和鹿
角。

还有种类繁多、小巧整齐、姿态优雅的鱼穿行在珊瑚丛中，或环游于珊瑚的四周。

[第3段译文］
在这些鱼群中游泳，它们似乎并不在乎。

我特别喜欢那些橘黄和白色相间的小鱼，它们藏在波动着的细长的海藻里.我也喜欢那些为大鱼清洁身体的小鱼——我甚至还看到这些小鱼游进大鱼的嘴里去帮它们清洁牙齿！当我用水下探照灯探索小石洞、暗礁和狭窄通道的时候，似乎每个角落都有使我感到惊奇的东西等着我:黄绿相间的鹦嘴鱼倒挂着，用它那像鸟嘴一样的硬嘴从珊瑚上吮吸微小植物；一条带着黄斑点的红色海蛞蝓从一个蓝色的海星旁边滑行过去；一只长相聪慧的大乌龟紧贴我的身旁而过，伸手便可触及。

[第4～6段译文]
还有一些其他的动物，我不想太靠近它们——一条带有利齿的鳗鱼，只是把头从石洞里伸出来，望着可供美餐的鱼过来（或者在等着我的美味脚趾伸过去！)；巨大的蛤蜊半掩在珊瑚礁中等着有什么东西游过来，游到它那宽厚的绿嘴唇中去。

然后，还有两条灰色的珊瑚鲨，每条大约有1。

5米长，突然从珊瑚礁后边游了出来。

我告诉自己它们并不危险，但是这样一点也不能抑制我那怕得要死的心情!
海水很浅，但是到了珊瑚礁的尽头,就有一个陡坡，一直下降到满是沙子的海底.它是边界的标志。

我游过珊瑚礁的边沿，浮在上面往下看海底的时候，我认为我还是非常勇敢的。

我的心急剧地跳动着—-在这样深邃而清澈的海水中,我感觉我彻底曝光了。

这个水底下的世界是多么美妙，多么漫无边际！而我在这个海洋的世界中又是多么渺小！
