Today`s lecture will center on prehistoric people of the Nevada desert.

今天的课将集中Nevada沙漠的史前人类。

Now, most of these prehistoric desert people moved across the countryside throughout the year.

现在(语气词)，大多数那些史前的沙漠人类一年四季穿行在乡下

You might think that they were wandering aimlessly—far from it!

你能会认为他们在漫无目的的游荡——远非如此。

They actually followed a series of carefully planned moves.

他们事实上遵从着一系列详细计划的迁移。

Where they moved depended on where food was available—places where plants were ripening or fish were spawning.

他们迁移到什么地方取决于什么地方能得到食物——植物在成熟或者鱼在产卵的地方。

Now often when these people moved, they carried all their possessions on their backs, but if the journey was long, extra food and tools were sometimes stored in caves or beneath rocks.

经常当那些人搬迁时，他们在他们背上携带者他们所有的财产，但如果行程太长，多余的食物和工具有时会保存在山洞里或者岩石下

One of these caves is now an exciting archaeological site.

那些洞穴之一，现在是一个令人激动的考古遗迹。

Beyond its small opening is a huge underground grotto.

在它小小入口的远端，是一个巨大的地底洞穴。

Even though the cave`s very large, it was certainly too dark and dusty for the travelers to live in, but it was a great place to hide things, and tremendous amounts of food supplies and artifacts have been found there.

尽管洞穴很大，对旅行者而言住在里面确实太黑和太脏(布满灰尘)，但他是一个藏东西的很棒的地方，而且里面已经被发现了数量惊人的食品给养和史前古人工器物。

The food includes dried fish, seeds, and nuts.

食物包括鱼干，种子和坚果。

The artifacts include stone spear points and knives; the spear points are actually rather small.

史前器物包括了石头制成的枪尖和刀子;枪尖实际上相当小。

Here`s a picture of some that were found. You can see their size in relation to the hands holding them.

这里有一些被发现(东西)的一张照片。你们能看到关于手持他们的尺寸(的对照)。
