在课文中有一段：

Under him, six or seven feet down, was a floor of perfectly clean, shining white sand, rippled firm and hard by the tides。Two greyish shapes steered there, like long, rounded pieces of wood or slate. They were fish. He saw them nose towards each other, poise motionless(一動不動), make a dart forward, swerve off(突然轉向, and come round again. It was like a water dance. A few inches above them, the water sparkled(閃光) as if sequins(光片) were dropping through it. Fish again myriads(無數) of minute fish, the length of his finger-nail, were drifting through the water, and in a moment he could feel the innumerable tiny touches of them against his limbs. It was like swimming in flaked(薄薄的) silver. The great rock the big boys had swum through rose sheer(徑直冒出來) out of the white sand, black, tufted lightly(輕輕捆住) with greenish weed. He could see no gap in it. He swam down to its base.

这一段 写的很好，我们先来看每一句讲的啥Under him, six or seven feet down, was a floor of perfectly clean, shining white sand, rippled firm and hard by the tides。从句法上看，用了一个倒装句，先说Under him, six or seven feet down在他下面六七英尺深的地方，凸显水的深度，使读者跟着小说的主人公的视线到海水深处，看到什么。floor指的是海洋的底，作者用perfectly clean, shining white sand描写了海底美妙的景象，这对于杰里来说是多么大的吸引。Sand，shining本身对儿童有吸引，比如：

   The children played all day in/on the sand. 孩子们玩了一整天沙子

儿童喜欢玩沙，更何况海底下的沙就别说了。

  Give thanks for each night.For colorful flowers, for stars shining bright. 感谢每一天。感谢每一个夜晚。感谢鲜艳的花儿，感谢闪闪发光的星星。
  天上的闪闪发光的星星对儿童有很强的吸引

Ripple在课文里表示显示出层层涟漪，这个词很有美感，在现代英语中这个词可以描写某件事造成的影响，也就是「引发波动」或「波及」之意，也可使用名词短语send ripples through:

This measure will send ripples through the economy. 这项措施将会引发经济波动

又如：

 have a major ripple effect on 对产生巨大的连锁反应

ripple far beyond影响远远超出了

第二句写杰里看到鱼：Two greyish shapes steered there两个灰色东西在游动，作者用steered描述鱼游动，steer的本义为驾驶：

She carefully steered the car around the potholes.她小心开车绕过那些坑洞。

This car is very easy to steer.这辆车很容易开。

She steered her guests into the dining room.她把客人们引到餐厅。

The main task of the new government will be to steer the country towards democracy.新政府的主要任务是将国家引向民主。

作者用steer暗示着正是眼前这美妙的景象把杰里引向更美妙的海底世界。

第4句He saw them nose towards each other, poise motionless(一動不動), make a dart forward, swerve off(突然轉向, and come round again.在课文注释34有一句：Note the five verbs used after “He saw them...”第一个动词 nose towards each other头对着头，第二个动词poise motionless(一動不動)，动词poise描述鱼抵着一动不动，这些鱼好沉着，稳重，镇静，四平八稳，蓄势待发，在口语中有：

You display great poise. 你表现得很镇静

第三个动词make a dart forward向前冲了一下，用dart描写鱼动作敏捷。

第四个动词swerve off转身游开。如：

Harry swerved out of the way。哈利猛地偏离原来的方向。

The bus driver swerved to avoid hitting a cyclist. 为了不撞上骑自行车的人，这辆公交车只好急转弯。
第五个动词come round again接着又聚拢在一起。

作者描述鱼的各种动作，使杰里着迷，他要是像鱼那样该多好啊。

It was like a water dance好像是水中舞蹈。这句话写得何等的好。写出杰里的心声。

A few inches above them, the water sparkled(閃光) as if sequins(光片) were dropping through it.离这两条鱼头顶几英寸处，水花闪闪，好像金属饰片撒下来一样。注意在sparkled后的as if把sparkled水花闪闪写活了，写具体了，光说sparkled水花闪闪还不味，再用as if画龙点睛。注意through与课文标题Through the Tunnel遥相呼应，暗示杰里也要像鱼那样were dropping through it，在水里穿来穿去drifting through the water,

杰里觉得那些鱼不是在水里游，而是在银片片里It was like swimming in flaked(薄薄的) silver.

作者写了鱼在水里游的神态，接着写孩子们从水里出来，没有写他们在水里是如何游的，就写他们从水里出来的神态。swum through rose sheer(徑直冒出來) out of the white sand穿过巨石在白沙滩上赫然耸立出来，请读者慢慢体会through妙处。

He could see no gap in it. He swam down to its base.他没有看见任何缝隙，于是他向下游到底部

no gap在口语中有“没有分歧”意思，

Between us there is no gap.我们两个没有分歧。

Gap Day：一日放松

black, tufted lightly with greenish weed描写了rock颜色是黑色的，但是上面些许覆盖着浅绿色的海草，tufted lightly with greenish weed中的tufted描述了一簇簇草覆盖在rock上。
