When you look up into the sky at night, have you ever felt that your eyes are playing tricks on (捉弄) you? It seems that the stars are moving all the time.
Actually, there is nothing wrong with your eyes. This twinkling effect is called scintillation (交光). Scintillation happens because of air movements in the earth’s atmosphere (大氣). Light is “bent (彎曲的)” when it travels through different parts of the earth’s atmosphere. As the air in the earth’s atmosphere is moving all the time, the light from the stars looks as if it is moving too.
The same thing also happens to things on the ground. On a very hot and shiny day, if you look at the road, the image in the distance is not clear and things move slightly. You can also see the same effect if you drop a rock into water. The rock appears a little unclear under the moving water.
This twinkling effect causes a lot of problems for astronomers (天文學(xué)家) since they cannot observe the stars clearly. A telescope (望遠(yuǎn)鏡) was sent into space so that the air movements in the atmosphere could be avoided (避免). It took a long time to build the space telescope but finally in 1990, a huge space telescope called the Hubble Space Telescope was successfully sent into space. Since then, astronomers have many important observations that have helped people understand space better.

How would we travel without maps? It would be a bit adventurous (冒險(xiǎn)的) to set off from Oxford University to go to London Bridge if there wasn't a map of the London Underground at each station. In fact, a lot of the early map-makers were adventurers and explorers, especially in the 15th and 16th centuries.

    So what did people do before there were maps? Well, it was quite easy to use natural signs like mountains and rivers if you were travelling on foot or riding a horse. People took small boats down rivers and followed coastlines. And it was much more logical (合理的) to use time, not distance, to measure (計(jì)量) journeys: the next village is a three-hour ride, for example.

    In fact, in the earliest maps, people didn't draw landmarks. They drew the stars. It was very easy to see the night sky and use it for navigation (航行). The sky was a lot clearer before the light pollution from cities that we have today. When towns and cities were built, people drew road maps which gave correct distances and directions.

    The London Underground was opened in 1863 and it also used a road map style. But a man called Henry Beck realized that travelling by train wasn't the same as driving your car across London. Passengers only needed to know which stations to change at. His new design (設(shè)計(jì)) for the Underground map wasn't very popular with the train companies at first. But the passengers loved it and in 1933, 700,000 copies were printed.

    These days, of course, you can ride a bike, drive a car or go through a forest and know where you are exactly, using a GPS. It's really difficult to get lost!

1.What was drawn in the earliest maps?

A. Stars.                             

B. Landmarks.

C. Cities and towns,                    

D. Mountains and rivers.

2.When did road maps come out?

A. Around 15th and 16th centuries.         

B. When people began to travel by train.

C. When people began to travel by sea.      

D. When cities and towns appeared.

3.Which of the following is true?

    A. A GPS helped people to travel long time ago.

    B. Ancient people could travel on a horse without maps.

    C. The sky was polluted by light before cities were built.

    D. Henry Beck's map wasn't popular with the passengers.

4.What is the main idea of the passage?

A. Maps have a long history.           

B. We never get lost these days.

C. We can't travel without maps.          

D. Henry Beck designed a new map.

Our nearest neighbor is the moon. In the sky,  the moon and the sun seem to be of the same size because the moon is much nearer.

The moon makes the tides—the changes in the level of the sea. The moon and the sun together pull the sea. In some parts of the world,  the difference between * high tide' (when the sea is very near to the land) and ' low tide' (when the sea is far away from the land) is very big. This is very important for ships.

The moon is very different from the Earth. Gravity on the moon is six times weaker than that on the Earth. There isn't any air. During the day,  it is very,  very hot but at night it is very,  very cold. Nothing can live on the moon.

If the moon goes between the Earth and the sun,  we have an eclipse of the sun(日食) . The moon stops the light from the sun and we have night in the day.

If the Earth goes between the moon and the sun,  we have an eclipse of the moon. The moon goes into the shadow( 影子) of the Earth and it disappears for a few minutes.

1. The sun to the Earth is _________times farther than the moon to the Earth.

A. nearly 200         B. less than 300      C. nearly 400         D. more than 400

 2.When the moon goes between the Earth and the sun,  we have night in the day, we call it the eclipse of

A. the moon      B. the sun          C. the stars        D. the Earth

3. Which of the following happens when we have an eclipse of the moon?

A. The Earth goes between the moon and the sun.

B. The moon goes into the shadow of the sun.

C. The moon goes into the shadow of its own.

D. The sun disappears for a few minutes.

4.Which of the following statements are TRUE?

a. The moon and the sun are of the same size.

b. Gravity on the Earth is 6 times stronger than that on the moon.

c. The changes in the level of the sea are called tides.

d. The moon itself pulls the sea and makes the tides.

e. When the sea is near to the land,  a high tide may happen.

f. It is much hotter in the day but much colder at night on the moon.

A. a. b. c. f.        B. b. c. d. e          C. a. d. e. f      D. b. c. e. f
