题目内容
8.A telescope (望远镜),called Gaia,is being designed by astronomers in Europe,and it couldn't be more different from Pan-STARRS,which is another telescope being designed.While Pan-STARRS will be looking for asteroids (小行星) and comets headed for Earth,Gaia will be looking at our entire galaxy (银河系).Gaia is designed to draw a map of the Milky Way,our home galaxy.Just as a map of your town gives you a picture of where things are located,Gaia's map of the galaxy will tell astronomers where the stars are.Over five years,Gaia will observe (观察) about a billion stars and other objects in our galaxy.Each object will be observed about 70times.
Gaia will be sent into space connected to a rocket.It contains two telescopes,each focused at a different angle (角度).These two telescopes act like Gaia's"eyes".The reason why humans can see things in 3D is that we have two eyes focused on the same object,at slightly different angles.By using two telescopes like eyes,Gaia can produce the first 3D map of the positions of the stars it views.
Gaia,which is to be sent into space in 2011,will be a powerful telescope.If you were to use it on Earth,for example,you could stand 600miles away from your best friends and still get a clear picture of their hair.
Gaia is one of more than a dozen telescopes being designed by scientists right now.The next generation of telescopes will reveal new parts of our universe that will seem surprising. The universe,with all its planets,stars and other strange objects,is a puzzle with pieces that we can see by using powerful telescopes.
32.How many different angles can Gaia focus at each time?A
A.2.
B.3.
C.4.
D.5.
33.The map to be drawn by GaiaD.
A.can show every building on Earth
B.can show you where your town is
C.will just show the stars around Earth
D.will show where the stars are in our home galaxy
34.What's Paragraph 4mainly about?C
A.What Gaia will do in space.
B.When Gaia will start to work.
C.How powerful Gaia will be.
D.What Gaia will do to Earth.
35.The underlined sentence in the last paragraph suggests that the next generation of telescopesD.
A.seem very surprising to scientists
B.will not be put into use in a short time
C.will just look at new things in universe
D.will be more powerful than the old generations.
分析 本文是一篇科教类阅读,属于说明文,本文主要介绍了威力强大的望远镜Gaia,并告诉人们新一代望远镜将比旧的更加强大.
解答 32.A.细节理解题.根据第三段前两句Gaia will be sent into space connected to a rocket.It contains two telescopes,each focused at a different angle (角度).可知,Gaia连接着火箭将被送上太空.它包括两个望远镜,每次都集中在在不同的角度.故选A.
33.D.细节理解题.根据第二段第二句Just as a map of your town gives you a picture of where things are located,Gaia's map of the galaxy will tell astronomers where the stars are.可知,由Gaia绘制的银河系的地图将告诉天文学家星星在哪里.故选D.
34.C.段落大意题.根据第四段第一句Gaia,which is to be sent into space in 2011,will be a powerful telescope.可知,Gaia将是一个强大的望远镜.故选C.
35.D.推理判断题.根据第五段倒数第二句The next generation of telescopes will reveal new parts of our universe that will seem surprising.可知,下一代的望远镜将显示出宇宙中似乎令人惊讶的新景象.可知新一代将比旧的更强的.故选D.
