These folks aren`t at an outdoor 3D movie, but they are using special glasses to check out something we reported on earlier this week. It`s an event that is truly once in a lifetime, because it won`t happen again for more than a century.

这不是在拍3D电影，但是他们确实在用特殊眼镜来观看这周我们早些报道过的一些事情。这件事情一辈子也就见一次，因为在这个世纪里也不会发生第二次。

We`re talking about the transit of Venus. The giant glowing thing is the sun. That little black dot passing in front of it is Venus. Now, remember, Venus and Earth are pretty close to each other in size, so this definitely gives you some perspective on just how big the sun is.

我们现在讨论的是金星凌日现象。那个巨大的发光的东西是太阳，在它边上一点点向它靠近的黑点就是金星，维纳斯。就是现在，记住这个时刻，金星和地球几乎一般大小。你能想象到太阳到底有多大。

One person who watched the transit in California said it was like watching grass grow, but he added, quote, "If you were told that grass only grows every 100 years, you`d probably want to watch it."

在加利佛尼亚一个观察到此过程的人说，整个事件发生的过程就像草类植物的生长过程，随后又说，如果这株草一百年长一次的话，你肯定愿意看。
