Attendance is not required, but you are responsible for all the information given in the class lectures. In the lectures I will talk about the chapters in the textbook and other material that I choose to supplement the course. The exams will cover all this information. Therefore, I advise you to come to the class as much as possible. If you have to miss a class, be sure to get the class notes from another student.
Your homework assignments are listed on the next page. You are supposed to read the chapter about which I will be lecturing before you come to class. This is to make sure that you understand as much as possible while taking notes in my lectures. Be prepared when you come to class. If there are any changes in the assigned homework reading, I will announce in class.
The term paper is 40% of your final grade. It should not exceed fifteen pages.（Anyone thinking of majoring in history may write twenty-five pages.）Before the mid-term exam you will choose the topic for your paper.
Have a good term!

On December 14, NASA (National Aeronautics and Space) blasted a small but mighty telescope into space. The telescope is called WISE and is about as wide around as a trashcan. Don't let its small size fool you: WISE has a powerful digital camera, and it will be taking pictures of some the wildest objects in the known universe, including asteroids, faint stars, blazing galaxies and giant clouds of dust where planets and stars are born.
"I'm very excited because we're going to be seeing parts of the universe that we haven't seen before," said Ned Wright, a scientist who directs the WISE project.
Since arriving in space, the WISE telescope has been circling the Earth, held by gravity in a polar orbit(this means it crosses close to the north and south poles with each lap (一圈).Its camera is pointed outward, away from the Earth, and WISE will snap a picture of a different part of the sky every 11 minutes. After six months it will have taken pictures across the entire sky.
The pictures taken by WISE won't be like everyday digital photographs, however. WISE stands for "Wide-field Infrared Survey Explorer." As its name suggests, the WISE camera takes pictures of features that give off infrared radiation (红外线辐射).
Radiation is energy that travels as a wave. Visible light, including the familiar spectrum of Light(光谱) that becomes visible in a rainbow, is an example of radiation. When an ordinary digital camera takes a picture of a tree, for example, it receives the waves of visible light that are reflected off the tree. When these waves enter the camera through the lens, they're processed by the camera, which then puts the image together.
Waves of infrared radiation are longer than waves of visible light, so ordinary digital cameras don't see them, and neither do the eyes of human beings. Although invisible to the eye, longer infrared radiation can be detected as warmth by the skin.
That's a key idea to why WISE will be able to see things other telescopes can't. Not everything in the universe shows up in visible light. Asteroids, for example, are giant rocks that float through space—but they absorb most of the light that reaches them. They don't reflect light, so they are difficult to see. But they do give off infrared radiation, so an infrared telescope like WISE will be able to produce images of them. During its mission WISE will take pictures of hundreds of thousands of asteroids.
Brown dwarfs(褐矮星)are another kind of deep-space object that will show up in WISE's pictures. These objects are "failed" stars—which means they are not massive enough to jump start the same kind of reactions that power stars such as the sun. Instead, brown dwarfs simply shrink and cool down. They're so dim that they're almost impossible to see with visible light, but in the infrared spectrum they glow.
74. What is so special about WISE?
A. Its digital camera can help astronomers to see the unknown space.
B. It is as small as a trashcan.
C. It is small in size but carries a large camera.
D. Never before has a telescope carried a digital camera in space.
75. The camera on WISE ________.
A. is not different from an ordinary camera
B. does not see infrared radiation while the ordinary camera does
C. reflects light that human eyes can see
D. catches the infrared radiation while the ordinary camera does not
76. Which of the following is NOT correct about "asteroids" according to paragraph 7?
A. Asteroids do not reflect light that reaches them.
B. Asteroids float through space giving off visible light.
C. It is difficult to take asteroids' pictures by ordinary cameras.
D. The WISE telescope can take pictures of asteroids.
77. What is implied in the last paragraph?
A. Brown dwarfs give off visible light.
B. Brown dwarfs are power stars like the sun.
C. Brown dwarfs give off infrared radiation.
D. Brown dwarfs are impossible to see with the WISE telescope.
