B Last night’s meteor(流星) shower left many people in the community dissatisfied and demanding answers.According to Gabe Rothsclild, Emerald Valley’s mayor,people gathered in the suburbs of the city, carrying heavy telescopes,expecting to watch the brightly burning meteors passing through the sky.What they found instead was a sky so brightened by the city’s lights that it darkened the light of the meteors passing overhead. “My family was so frustrated,” admitted town resident Duane Cosby, “We wanted to make this an unforgettable family outing,but it turned out to be a huge disappointments.” Astronomers---scientists who study stars and planets----have been complaining about this problem for decades.They say that light pollution prevents them from seeing objects in the sky that they could see quite easily in the past.They call on people and the government to take measures to fight against it. There is yet a population besides professional and amateur star observers that suffers even more from light pollution. This population consists of birds,bats frogs,snakes,etc. For example,outdoor lighting severely affects migrating(迁徙的)birds.According to the International Dark-Sky Association. “100 million birds a year throughout North America die in crashes with lighted buildings and towers.” Countless more animals casualties(伤亡)result from the use of artificial lighting.Clearly,people enjoy the benefits of lighting their evenings,but some scientists think it can be harmful for humans,too. They worry that exposure to light while sleeping can increase person’s chances of getting cancer. Emerald Valley is only one community that is becoming aware of the negative effects of hight pollution.For years,Flagstaff,Arizona,has enforced lighting regulations in its city in order to assist astronomers at the Lowell Observatory.Similar efforts have been made worldwide,and a movement is underway to remind us to turn off lights when we are not using them,so that other creatures can share the night.
【題組】42.What do the astronomers complain about?   
(A)Meteor showers occur less often than before   
(B)Their observation equipment is in poor repair   
(C)Light pollution has remained unsolved for years   
(D)Their eyesight is failing due to artificial lighting

(二) You may have heard references made to the “dark side” of the moon. This popular term refers to the fact that the same physical half of the moon, the “near side,” is always facing the earth, which in turn means that there is a far side or so-calleddark sidethat is never facing the earth and can only be seen from space.
     This phenomenon has nothing to do with the periodic light and dark we see as the phases of the moon change. Sometimes people refer to a new moon as a “dark moonbecause the moon is fully in shadow as viewed from the earth, but that’s not the same thing as the dark side of the moon. The side of the moon facing us during a new moon is the same as any other moon phase, such as a full moon when we can see the entire face
     So why can we only see one side of the moon from the earth? We all know that the earth rotates on its own axis, so theoretically, the moon should also do the same, allowing us to get a full picture of the planetoid. Why are we limited to seeing only half the picture? It turns out that the speed at which the moon rotates has led to this particular phenomenon. Millions of years ago, the moon spun at a much faster pace than it does now. However, the gravitational influence of the earth has gradually acted upon the moon to slow its rotation down, in the same way that the much smaller gravitational influence of the moon acts upon the earth to create tides. This influence slowed the rotational period of the moon to match that of its orbitabout 27.3 days – and it is now “locked in” to this period.
     Another interesting fact is that actually a little bit more than half of the moon’s surface is observable from the earth. Since the moon’s orbit is elliptical, and not circular, the speed of its orbital travel increases and decreases depending on how close it is to our planet. However, the rotational speed of the moon is constant. This difference between orbital speed and rotational speed means that when the moon is farthest from the earth, its orbital speed slows down just enough to allow its rotational speed to overtake it, giving observers a small glimpse of the usually hidden area. The term for thisrocking motion" of the moon is called libration and it allows for 59 percent of the moon to be seen in total
    Finally, one reason that the far side of the moon is frequently referred to as the “dark side” is because many people mistakenly think that it never sees any light from the sun. In that sense the termdark side” is wrong and misleading. In fact, since the moon is constantly rotating on its own axis, there is no area of the planetoid which is in permanent darkness, and the far side of the moon is only completely devoid of sunlight during a full moonwhen the sun is facing the moon with the earth in between.

【題組】75. What does rocking motion refer to?
(A) The process of rock formation on the moon.
(B) Wobbles felt when the moon rotates on its axis.
(C) Meteor rocks falling on the moon’s surface.
(D) The speed change in the moon’s orbital travel.
