(B) Take any long piece of paper. Now glue the ends of the paper together. You have made a ring. Take a second long piece of paper. Twist the paper once and glue the ends together. Now you have made a Mobius band(带). For people who study math, this band is unusual. This band was first made in the 1800s by a German man named August Mobius. Mr. Mobius studied math. He wanted to find a way to show how this band works with math. Believe it or not, this band has only one surface. You can find this out for yourself. If you draw a line on the surface of the paper before you twist and glue it, the line is only on side of the paper. The paper has two surfaces. But if you draw a line after you make the Mobius band, you can follow the line around all sides of the paper. In other words, the Mobius band must have only one surface. It’s a kind of fun to see what happens when you cut the band. If you cut the Mobius band in half once down the line you draw, you don’t get two Mobius bands. Instead, after you cut the band, it turns into one large twisted ring. Then, if you cut the band again, you get two connectedMobius bands. Try it! 1. What is a Mobius band? A. a math problem B. an interesting twisted ring C. a long piece of paper D. two connected rings 2. Which is right about August Mobius? A. He studied math. B. He was a German. C. He made the first Mobius band. D. All of the three. 3. How can you see that the Mobius band has only one side? A. Cut it. B. Draw a line on it. C. Glue it D. Twist it. 4. What do you get if you cut the Mobius band in half once? A. a large twisted ring B. two Mobius bands C. a long piece of paper D. two long pieces of paper 5. What do you get if you cut the Mobius band in half twice? A. one large twisted ring B. a long piece of paper C. two Mobius bands D. a short piece of paper 查看更多

The best way of learning a language is using it. The best way of learning English is talking in English as much as possible.

The word “day” has two meanings. When we talk about the number of days in a year, we are using “day” to mean 24 hours. But when we talk about day and night, we are using “day” to mean the time between sunrise and sunset. Since the earth looks like a ball, the sun can shine on only half of it at a time. Always one half of the earth is having day and the other half night. A place is moved from day into night and from night into day over and over by the spinning(旋转)of the earth. At the equator(赤道)day and night are sometimes the same length(长度). They are each twelve hours long. The sun rises at 6 o’clock in the morning and sets at 6 o’clock in the evening. For six months the North Pole is tilted(倾斜)toward the sun. In those months the Northern Hemisphere(半球)gets more hours of sunlight than the Southern Hemisphere. Days are longer than nights. South of the equator nights are longer than days. For the other six months the North Pole is tilted away from the sun. Then the Southern Hemisphere gets more sunlight. Days are longer than nights. North of the equator nights are longer than days. Winter is the season of long nights. Summer is the season of long days.

(   )6.When the Western Hemisphere is having day, the Eastern Hemisphere is having ________.

       A. both day and night              B. day

       C. neither day nor night            D. night

(   )7. A place is moved from day into night and from night into day over and over by ________ of the earth.

       A. the pushing                    B. the pulling

C. the spinning                    D. the passing

(   )8. At the equator day is as long as night ________.

          A. sometimes     B. never       C. usually        D. always

(   )9. When the North Pole is tilted toward the sun, the Northern Hemisphere gets ________ sunlight.

      A. less           B. more       C. all            D. no

(   )10. When it is winter in China,  ________.

      A. the USA is tilted toward the sun

      B. the South Pole is tilted away from the sun

      C. the North Pole is tilted toward the sun

      D. the North Pole is tilted away from the sun
