In 1967，we can hear some radio signals. They were coming from a point in the sky where there was unknown star. They were coming very regularly, too: about once a second, if they were controlled by clock. Although some scientists heard the signals, they did not tell others. They were rather afraid to tell in case they frightened people. The signals were coming from a very small body—no bigger, perhaps than the earth. Was that why no light could be seen from it? Or were the signals coming from a planet that belonged to some other star?There was no end to the questions, but the scientists kept the news secret.“Perhaps there are intelligent beings out there.”they thought,“who are trying to send messages to other planets, or to us? So the news was not given to the newspaper. Instead, the scientists studied the signals and searched for others like them...Well, all that happened in 1967 and 1968.Since then scientists have learnt more about those strange, regular, radio signals .And they have told the story, of course. The signals do not come from a planet; what they come from is a new kind of star called a “pulsar””.About a hundred other pulsars have now been found, and most of them are very like the first one. The strong radio stars are Pulsars . They are the smallest but the heaviest stars we know at present. A handful of pulsar would weigh a few thousand tons. Their light—if they give much light—is too small for us to see. But we can be sure of this, no intelligent beings are living on them. 56. In this text, we can know that the radio signals ____. A.were regular B.were controlled by a clock C.were only heard in 1967 D.were secret messages 57. Who sent the radio singals? A.a satellite B.a planet C.a sky body which was unknown at that time D.intelligent human who were unknown at that time 58. The reason why the scientists did not tell people about the signals is that ___. A.the singals stood for secret messages B.people would ask them too many questions C.they did not want to frighten people D.they stood for unimportant messages 59. From this passage, what is the definition of “ pulsar”? A. a small heavy star which sends out strong radio signals and cannot be seen
