26、    If you are like most people，your intelligence(智商)changes from season to season．you are probably a lot sharper in spring than you are at any other time of the year．A famous scientist，Ellsworth Huntington (1876-1947)got a result from people’s work and himself．He found our mental abilities(智力能力)would be influenced by different seasons and temperatures．

    He found that cool weather is much better for creative thinking than hot weather．This does not mean that people are not clever in summer．It does mean，however ,that the mental abilities of large numbers of people may be low in summer．

25、    Is it difficult for you to get up in the morning? Hiroyuki’s bed will solve your problem! Here is how it works．

    The bed is connected to an alarm(闹钟)clock．First，the alarm clock rings．You have a few minutes to wake up．Next，a tape recorder in the bed plays soft music．The tape recorder in Hiroyuki’s bed plays a recording of his girlfriend．She whispered in a soft voice，”Wake tip，darling，please．”A few minutes later， Hiroyuki hears a recording of his boss．His boss shouts，”Wake tip at once，or you’ll be late!” If you don’t get Lip after the second recording，a mechanical(机械的) ”foot” in the bed will kick you on the head．The bed waits a few more minutes．What! You’re still in bed! Slowly the top of the bed rises higher and higher．The foot of the bed goes lower and lower．Finally you slide(滑)off the bed and onto the floor．You are out of bed awake!

    Hiroyuki’s bed is not in stores．There is only one bed——the bed Hiroyuki made for a contest(比赛)．Maybe someday a company will make Hiroyuki’s bed and sell it in stores．Maybe people will buy millions of beds．Then Hiroyuki will be rich．If the bed makes Hiroyuki rich，he won’t need to work，and he won’t need to get up early!

24、    We have always been interested in the moon．2000 years ago people a1ready knew it moved around the earth and where it would be in the sky at different times of the year．At that time，everything about the moon was learned by watching it carefully in the sky．

    When scientists could use telescopes(望远镜)to study the moon more closely，their ideas began to change．They could see the moon was made of rocks．Most scientists thought moon rocks would be different from those on Earth．This was because they believed the moon had once been a planet(行星)that had been caught in the earth’s gravity(引力)millions of years earlier

    In 1969 moon rocks were finally brought to the earth and studied．Much to their surprise，scientists found that，except for water，the moon and the earth were made of the same thing．Once again new ideas were needed for this new information．

    After years of study，most scientists now think that the moon was once part of Earth．They believe very early in its history，maybe 4 million years ago，something about the size of Mars(火星)hit Earth．This sent billions of rocks into space around our planet．These rocks slowly joined together and after many years became the moon．

    In the future，even though our ideas about the moon may change again，we will still be interested in it．

    A．part of the earth billions of years earlier
