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?
【小题1】 Which picture means "it's not safe land"?
【小题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. |
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 |

The Internet, mobile phones and Ipads are part of our lives now. Technology is greatly affecting all ways of our lives, from the ways we work to the ways we play. And it even causes a number of social problems such as cloning humans.
We have had lots of technology and it has changed our lives a lot. There is no doubt that humans will continue to use more and more technology. Here are some examples of modern technology that will change our ideas and will affect our lives greatly.
Global positioning system (GPS) (全球定位系统)
It’s a system that uses radio signals from satellites to show exact(精确地) information. It tells you where the user is on the earth in all weather conditions. It’s made up of three parts: satellites, control equipments (设备) on land and receivers.
Space Technology
Russian and American scientists have worked together for the international Space Station (ISS) for a long time. They hope the ISS will provide a long-lasting lab. Such a lab will bring humans limitless(无限的) advantages. It’s even hoped that one day space technology will take humans to their new houses in space.
Underwater Robot
Hercules is a kind of underwater robot with some high technology equipments. It will be used to search for ancient ships which were destroyed into the deep sea during their journey long ago.
The world is changing so quickly that it’s hard for us to catch up with all the new inventions because they seem to come out every month. It’s important for us to learn about new technology and the role that it plays in our lives. So we should be willing to accept modern technology, or we will fall behind the times.
【小题1】______ can tell you where the user is on the earth exactly.
A.Satellites | B.Receivers |
C.Global Positioning System | D.Underwater Robot |
A.It has carried people to other planets. |
B.It will provide a long-lasting lab for us. |
C.Russian and American are working for it. |
D.Humans will get a lot of advantages from it. |
A.save lives in the sea | B.take picture in the sea |
C.repair the broken ships | D.look for the ancient ships in the sea |
A.the use of GPS is affected by the weather conditions |
B.it’s very important for us to learn about new technology |
C.it’s easy for us to catch up with all the new inventions |
D.technology brings us many advantages such as cloning humans |
A.To help us study some new technology. |
B.To tell us technology is changing the world. |
C.To help solve the problems that technology causes. |
D.To remind us the advantages of technology are limitless. |

One evening last July, my old car broke down on a highway.It was an hour before sunset, and.I was 25 miles from home.I couldn't reach anyone to pick me up, so I decided to take a bus.

“I just can't leave you here,”she said.“I'll give you a ride home.”
“You'll drive me home in the bus?”I asked, confused.
“No, I'll take you in my car,”she said.
“It's a long way,”I answered.
“Come on, sir,”she said.“I have nothing else to do.”
On the way, she told me a story.A few days earlier, her brother had run out of gas.A good Chinese man had picked him up, taken him to a gas station and then back to his car.“I'm just passing the favor along,”she said.
When I offered her money as a thank-you, she wouldn't accept(接受)it.“That wouldn't make it a favor,”she said.“Just do something nice for somebody.”Pass it along.
