托福听力荟萃 64（在线收听）

Most people think of astronomers as people who spend their time in cold______through telescopes every night. In fact, a typical astronomer spends most of his or her time analyzing data and may only be at the telescope a few weeks of the year. Some astronomers work on purely_____problems and never use a telescope at all. You might not know how rarely images are viewed directly through telescopes. The most common way to observe the skies is to photograph them. The process is very simple. First, a______is_____with a________material. The plate is_______so that the image received by the telescope is recorded on it. Then the image can be developed, enlarged, and published so that many people can study it. Because most astronomical objects are very remote, the light we receive from them is rather______. But by using a telescope as a camera, long time exposures can be made. In this way, objects can be photographed that are a hundred times too faint to be seen by just looking through a telescope.

【参考译文】

大多数人认为，人谁花的时间，通过望远镜窥视，每天晚上在寒冷的观测天文学家。事实上，一个典型的天文学家，他或她的时间都花在分析数据，可能只有在望远镜在几个星期的一年。一些天文学家纯粹的理论问题和工作，从来没有使用望远镜在所有。你可能不知道，只有很少的图像通过望远镜直接观看。观察天空的最常用的方法是向他们拍照。这个过程是非常简单的。首先，照相板涂覆用感光材料。被定位成使得由望远镜接收的图像被记录在其上的板。然后，该图像可以开发，放大，并公布，让很多人可以学习它。由于大多数天文对象是很偏僻，我们从他们的光比较微弱。但用望远镜作为一个摄像头，可以很长一段时间的风险。通过这种方式，可以拍摄对象，一百倍太微弱，只是通过望远镜看到。
