　　2026年6月四级英语阅读理解模拟题（18）

　　Some radio singals were heard in 1967.They were coming from a point in the sky where there was unknown star.They were coming very regularly,too:about once a seco nd,if they were controlled by clock.

　　The scientists who heard the signals did not tell anybody else.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;they come from 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.

　　Pulsars are strong radio stars.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.

　　21. The radio signals discussed in this passage____.

　　A.were regular B.were controlled by a clock

　　C.were heard in 1967 only D.were secret messages

　　22. The radio singals were sent by____.

　　A.a satellite B.a planet

　　C.a sky body which was unknown at that time

　　D.intelligent beings who were unknown at that time

　　23. The scientists did not tell people about the signals because____.

　　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

　　24. A pulsar is____.

　　A. a small heavy star which sends out strong radio signals and cannot be seen

　　B. a small heavy planet which sends out strong radio signals and cannot be seen

　　C. a small heavy satellite which sends out strong radio signals and cannot be seen

　　D. a small intelligent being who sends out strong radio signals and cannot be seen

　　25. Which of the following is true?

　　A.One of the pulsars found by scientists sends radio signals.

　　B.Pulsar began to send radio singals in 1967.

　　C.Scientists have searched for pulsars for many years but found none.

　　D.Scientists have found many pulsars since 1967.

　　参考答案：

　　21. 答案A。见原文第一段，“They were coming very regularly,too.”他们同样非常有规律，与 A)项同意。B)were controlled by a clock.由时钟控制，原文前面有一表示“似 乎的”连词 if。C)，D)根据下文判断都不正确。

　　22. 答案C。见原文第三段“...they come from a new kind of star called a “pulsar

　　””他们来自一种叫脉冲星的新型恒星。 A) a satellite卫星，B)a planet行星，D)当时未 知的智能生命。

　　23. 答案C。见原文第二段开头“ The scientists who heard the singals did not tell anybody else.They were rather afraid to tell in case they frightened people.”听到该信号的科学家未告诉别人，他们害怕这样会惊吓了老百姓。因此选择 C。

　　24. 答案A。 见原文第四段，实际由“star”这个单词就可排除B)，C)和D)选项。

　　25. 答案D。见原文第三段最后一句“About a hundred other pulsars have now been found...”因此D)项正确，其他各项均与原文意思不符。
