1. 阅读A篇短文，从各题所给的A、B、C、D四个选项中，选出最佳选项。

A

    Jupiter(土星) is the fifth planet from the sun and it is the largest one in the solar system. It is about 11 times bigger than the earth. Jupiter's strangest thing is its huge red spot. Pictures taken from space tell us that the red spot is probably a hurricane(飓风). It is so big that the earth would fit right in the middle of it. Sometimes the hurricane looks like a huge oven with orange-red waves (波浪). Some other time the color almost disappears.

    On the earth, hurricanes move. We can watch them travel across water to land. Jupiter's red spot also moves. Scientists say it “walks”. It is carried along by air in Jupiter's atmosphere(大气层).

    So far, Jupiter has been visited by four spacecrafts. All of them flew by Jupiter very quickly. On the next trip to Jupiter, a spacecraft will stay near the planet much longer. New information will be sent back to the earth. Soon scientists will know much more about this strange red spot in the atmosphere.
