听力原文： The water level of oceans rises and falls alternatively twice a day. This movement of water is called the tide. Tides are caused by the pull of the sun and the moon on the earth's surface; since the moon is much closer, it affects the tides more than the sun. When the moon is directly overhead, it actually pulls on the water that is below it. This causes the water level to rise because the water is pulled away from the earth. As the moon disappears over the horizon, the pull lessens and the water level settles back towards the ocean bottom.
When the water reaches its highest level, we have high tide. And when the water reaches its lowest level, we have low tide. From its lowest point, the water rises gradually for about six hours until it reaches high tide. Then it begins to fall continuously for about six hours until it reaches low tide. Then the cycle begins again.

A．Every other day.
B．Twice a week.
C．Twice a day.
D．Only during the summer.
The Threat to Kiribati
The people of Kiribati are afraid that one day in the not-too-distant future, their country will disappear from the face of the earth-literally. Several times this year, the Pacific island nation has been flooded by a sudden high tide. These tides, which swept across the island and destroyed houses, came when there was neither wind nor rain. "This never happened before," say the older citizens of Kiribati.
What is causing these mysterious high tides？ The answer may well be global warming. When fuels like oil and coal are being burned, pollutants (污染物) are released; these pollutants trap heat in the earth's atmosphere. Warmer temperatures cause water to expand and also create more water by melting glaciers (冰川) and polar (极地的) ice caps.
If the trend continues, scientists say, many countries will suffer. Bangladesh, for example, might lose one-fifth of its land. The coral (珊瑚) island nations of the Pacific, like Kiribati and the Marshall Islands, however, would face an even worse fate-they would be swallowed by the sea. The loss of these coral islands would be everyone's loss. Coral formations are home to more species than any other place on earth.
The people of these nations feel frustrated. The sea, on which their economies have always been based, is suddenly threatening their existence. They don't have the money for expensive technological solutions like seawalls. And they have no control over the pollutants, which are being released mainly by activities in large industrialized countries. All they can do is to hope that industrialized countries will take steps to reduce pollution.
The people of Kiribati worry that one day their country will be taken away by a sudden high tide.

We believe, however, that some two thousand million years ago, another star wandering (漫游) through space, happened to come near our sun. Just as the sun and the moon raise tides (潮汐) on the earth, so this star must have raised tides on the surface of the sun. But they were very. different from the small tides that are raised in our oceans; a large tidal wave must have travelled over the surface of the sun, at last forming a mountain so high that we cannot imagine it. As the cause of the disturbance (动荡) came nearer, so the mountain rose higher and higher. And before the star began to move away again, its tidal pull had become so powerful that this mountain was tom to pieces and threw off small parts of itself into space. These small pieces have been going round the sun ever since. They are the planets (行星).
Millions of stars are______.
A．following a regular path in space
B．moving about without a fixed course
C．seldom wandering about in the universe
D．always travelling together
