It is a thousand kilometers across that desert (沙漠). The road is 16 nearly all the way. Sometimes there is a deep sand. A driver must then put his foot down hard and drive through! There are three small  17 along the way. Vick reached the first place at ten o‘clock p. m. He had his  18 in a little restaurant there. It was a warm  19 in August. Vick wanted to 20 through the night. The nights are warm enough in August, but the days are very, very  21 .

  He left the restaurant at 11:30 and drove over  22 hours. There wasn’t a moon, but the  23  were wonderful. There was nothing else on the road. Vick thought, “It‘s an empty desert. No tree, house, man.” He could  24 the endless, white road in the car’s headlights(车灯). A million stars looked down on him.

  It was two o‘clock in the morning. Vick stopped the car. He was two hundred kilometers from the 25 town: “I’ll light the cooker,” he thought, “and make some tea. ” He got out of the car.

  He heard some sounds, ten or fifteen meters  26 . He could not see anything in the darkness. A man said, “Good morning. It‘s a 27 morning, isn’t it?” The man came forward,out of the darkness; out of the desert. Vick did not move. The man said, “You are going to 28 some tea, aren‘t you? I often get a cup of tea at this time. It’s two o’clock. Cars always 29  near here at this time. Sometimes I get a 30 . Now listen, and I’ll tell you a story. Then you‘ll give me…”

As we all know, the ocean moves. But waves breaking on the beach make the ocean fun. When you stand on the shore and look at the waves, it seems like the water is moving towards you. But the water is not really moving forward. The moving you see is wave energy. And wave energy comes from the wind.

Let’s think about how this works. As wave energy passes through the water, the energy makes particles (粒子) of water move up and down. Just give you an example of a wave passing under a basketball. We put a basketball on the sea. When the wind blows, a wave comes from behind the basketball. The basketball moves up to the top with the wave. Then the wave continues and leaves the basketball behind. The basketball looks lower, but it doesn’t move forward. That’s because the wave energy just moves the water which is under the basketball.

   So why can you see a wave knock you down on the shore?When a wave moves toward the shore, the bottom of the wave slows down because it meets the ocean floor. But the top, which is called crest(浪峰), keeps moving. The different action causes the wave to fall over or break onto the shore. If a wave is very large, it carries a lot of energy when it hits the land. As time goes by, waves can break up and carry away the rocks and other things on the shore. Shorelines are changing all the time because of wave action.

1.______ is really moving forward when you look at the wave.

A.Water            B.The basketball      C.Water and wave energy   D.Wave energy

2.Match the sentences with the pictures and the right answer.

(1) The basketball moves up to the top with the wave.

(2) The basketball continues and leaves the basketball behind.

(3) When the wind blows, a wave comes from behind the basketball.

A.a—(2) b—(1) c—(3)                     B.a—(3) b—(1) c—(2)

C.a—(1) b—(3) c—(2)                     D.a—(3) b—(2) c—(1)

3.Which of the following is NOT true according to the passage?

A.Wave energy comes from the water.

B.Large waves carry plenty of energy.

C.Wave action makes shorelines change all the time.

D.The bottom of the wave is easy to slow down.

4.The underlined word “it” ( Paragraph 3) refers to “________”.

A.particles of water   B.the shore          C.the wind          D.the bottom of the wave

5.The main idea of this passage is ______.

A.what makes particles of water move         B.how a basketball moves on the ocean

What do you do if you're stranded(处于困境的)on a lonely island? Surely you need to find a way to get in touch with the outside world. Your best chance of doing this is to draw the attention of a passing plane.

  Body signals(信号)

  Pilots from different countries understand body signals if they have the correct training. When you wave your arms up and down in a straight line, it means "yes". When you point downwards and swing your arm from side to side, it means "no". If you want the pilot to know that it's safe to land, push your hands out in front of you and bend(弯曲)your knees. If you want to say that it's not safe to land, put your arms in the air and move them to one side.

  Smoke signals

  The smoke from a fire can be seen from far away, so it's a good way to draw attention. If the weather is dry, it isn't hard to start a fire. Remember, however, that fires can be very dangerous if they get out of control. Never light a fire unless you're sure that it can't spread. If the ground is dark, light smoke can be seen more easily. Green grass and leaves produce light smoke.

  Ground-to-air signals

  It's a good idea to build some signals, too. Use large pieces of wood to make the symbols(标记). If you can't find any wood, use earth. Some useful symbols are:

  F "I need food and water."

  II "I need medicine."

  I "I am badly hurt."

  X" I am unable to move from here."

  Pilots' replies

  If the pilot lowers the plane's wings from side to side, this means "message received and understood". (At night, the pilot flashes the plane's green lights.) If the pilots flies the plane in a clockwise circle, this means "message received but not understood".(At night, the pilot flashes the plane's red lights.)

However, there is no signal which means "message not received". Why not?

 

1. Which picture means "it's not safe land"?

 

 

 

 

2. What can we learn from the passage?

  A. Swinging your arm from side to side means "yes".

  B. If the ground is dark, light smoke can't be seen.

  C. If you need some medicine, make a symbol "II".

  D. The pilots make replies with a blue light at night.

  3. What is the passage mainly about?

  A. The explanation of building signals on an island.

  B. The importance of making signals on an island.

  C. Ways of sending out signals on a lonely island.

D. Ways of receiving signals from a lonely island
