A group of frogs were traveling through the woods, and two of them fell into a deep hole. When the other frogs saw how deep the hole was, they told the two frogs that they were hopeless to be alive. But the two frogs didn’t believe it. 1. . The other frogs kept telling them to stop and wait for their death. Finally, one of the two frogs gave up and fell down. Soon he died.

The other frog continued to jump as hard as he could. Once again, the crowd of frogs shouted at him and told him to stop and just wait to die. 2. .

When he got out, the other frogs said: “Didn’t you hear us?” The frog explained to them that he was deaf. 3. .

The story teaches us two lessons. 4. . An encouraging word to someone who is down can cheer him up and help him make it through difficulties. Secondly, a destructive (消极的) word to someone who is down can make him give up and die. So be careful of what you say.

Speak life to those who cross your path. It is sometimes hard to understand that an encouraging word can go such a long way. It is great for a person to take the time to encourage another.

A. Then the two frogs began to stop jumping

B. But he jumped even harder and finally he made it

C. Firstly, there is power of life and death in the tongue

D. So he thought they were encouraging him at that time

E. They tried to jump up out of the hole with their efforts

Imagine you’re at a party full of strangers. You’re nervous. Who are these people? How do you start a conversation? Luckily, you’ve got a thing that sends out energy at small chips(芯片) in everyone’s name tag(标签).The chips send back name, job, hobbies-whatever. Making new friends becomes simple.

This hasn’t quite happened in real life. But the world is already experiencing a new age of using RFID technology.

An RFID tag with a small chip can be fixed in a product, under your pet’s skin(皮肤), even under your own skin. Some RFID tags have no energy source because they do not need it. The energy comes from a scanning device(扫描装置), which sends out energy and starts up the tag immediately.

Such a tag carries information to that object, and the information can be renewed. Already, RFID technology is used for recognizing(识别) each car or truck on the road and it might appear in your passport. Doctors may put a small chip under the skin to get a patient’s medical records. At a nightclub in Paris or in New York the same chip might get you to pay for the bill with the wave of an arm.

Take a step back: 10 or 12 years ago, you would have heard about the coming age of computing. One example always seemed to surface: Your refrigerator would know when you needed to buy more milk. The idea was that computer chips could be put everywhere and send information in a smart network that would make life simpler.

RFID tags are a small part of this situation. “The world is going to be a connected set of personal small devices.” predicts Dr. J. Reich. But some people are nervous about the possibilities of such technology. It goes too far tracking(跟踪)school kids through RFID tags, they say.

When Marconi invented radio, he thought it would be used for ship-to-shore communication, not for pop music. Who knows how RFID and other technologies will be used in the future. Here’s a wild guess: Not for buying milk.

1.The article is intended to______.

A. warn people of the possible risks in adopting RFID technology

B. explain the benefits brought about by RFID technology

C. convince people of the uses of RFID technology

D. predict the applications of RFID technology

2.We know from the passage that with the help of RFID tags, people_____.

A. will have no trouble getting data about others

B. will have more energy for conversation

C. will have more time to make friends

D. won’t feel shy at parties any longer

3.Passive RFID tags chiefly consist of____.

A. scanning devices B. radio waves

C. batteries D. chips

4.Why are some people worried about RFID technology?

A. Because children will be tracked by strangers.

B. Because market competition will become fiercer.

C. Because their private lives will be greatly affected.

D. Because customers will be forced to buy more products.

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
