A number of years ago， a man went to visit a circus（马戏团） in New York．He was able to walk around looking at the lions， monkeys， bears and other circus animals．As he was passing the elephants， he suddenly stopped．He found that these huge elephants were being held by only a small rope tied to their front leg．No chains， no cages．It was clear that the elephants could，at anytime，break away from their ropes but for some reason， they did not．
He saw a trainer nearby and asked why these animals just stood there and didn't try to get away．"Well，"the trainer said，"when they are very young and much smaller，we use the same size rope to tie them and，at that age，its enough to hold them．As they grow up．they still believe they can not breakaway．They believe the rope can hold them， so they never try to break free．"
"How could it be？"said the man．These animals could at anytime break free from ropes．But because they were always stuck right where they were， they believed they couldn't．
Just like the poor elephants， how many of us go through life believing that we can not do something， just because we failed at it once before？

The air plant has wonderful and amazing features. It takes in moisture(水汽)from the air through its leaves．Although it is seen growing on another object or plant to support itself.
To prevent the roots from being too wet，avoid(避免) planting it in soil. Keep the roots in a well—ventilated(通风良好的)environment. Air plants can grow well hanging from fishing lines. They can also be hung from seashells, teacups or even on wood.
Water the air plant once in a while. Simply let the water fall from the roots. The roots will take in the water for the air plant. The air plant can live between 0℃° and 51 ℃. It does not need to be in the light all the time. However, sunlight(morning and evening only)helps it to reproduce(繁殖)faster. When it flowers，it turns a colorful pink, red or orange．At most 8 young plants can grow from the air plant．When these grow to half the size of the parent plant, simply pull them away gently from the parent plant and plant them in another place．
The lifespan of an air plant depends on the care it gets and the environment it is placed in. Generally, all air plant can live for many years.
Because they are so beautiful and easy to take care of, air plants are excellent as birthday gifts or housewarming gifts.The air plant takes in moisture from ______.

We may know that there are four basic periods(时期) for human beings to pass through when you enter and live in another country. This process helps you deal with culture shock（冲击）.
Culture shock begins with the "honeymoon period". This is the time when you first arrive in a place where everything about the new cu1ture is strange and exciting. You see new things, hear new sounds and language, eat new kinds of food. This period can last for quite a long time because you feel very happy.
Unluckily, the second period can be more difficu1t. After you have got used to your new life, you can become very tired and begin to miss your motherland, your family, your friends, your pets and so on. Al1 the little prob1ems in life seem to be much bigger and more worrying when you face them in a foreign country. This period can be very difficult and lead to moving backwards quickly.
The third period is called the "adjustment period". This is when you begin to realize that things are not so bad in the new country. Your sense of humor usually becomes stronger and you realize you are becoming stronger by 1earning to take care of yourself in the new place. Things are still difficult, but you are now a survivor.
The fourth period can be cal1ed "at ease at last". Now you feel quite comfortable in your new place. You can deal with most problems that you have. You may still have prob1ems with language, but you know you are strong enough to deal with them. At this time, you may feel a little uncomfortable if you go back to your motherland.According to the passage, culture shock usually happens when you ______.
| A．get married to a foreigner |
| B．live in a big city |
| C．go to live in a foreign country |
| D．meet foreigners in your motherland |
During the first period of the process, you feel _________.
| A．sad and lonely | B．happy and excited |
| C．angry but strong | D．easy but uncomfortable |
You will find that you are a survivor in _______.
| A．the 1st period | B．the 2nd period |
| C．the 3rd period | D．the 4th period |
The fourth period can be regarded as a period of being _____.
| A．relaxing | B．worrying |
| C．tiring | D．disturbing |
From the passage we can conclude that ______.
| A．living in another country is fun |
| B．it’s boring to live in another country |

Camilla Chomp was a strange little girl. She liked to spend her time alone eating chocolate. Her parents were worried, so they took all the chocolate away.
Camilla left her house to look for some chocolate. She found a small house full of bottles. Among the bottles, a blue bottle caught Camilla’s eyes. It was full of chocolate. In the bottle there was also a card with the words “Change tears(眼泪) into chocolate.”
Camilla was very excited. She ran out of the house with the bottle to look for someone crying. First, she met a little boy crying hard and collected his tears. The tears were quickly changed into chocolate. While Camilla was collecting the tears, she comforted the boy. Finally, the boy stopped crying and they had a good time together.

Have you ever had dreams about building a robot? Or putting together a spaceship? Or even seeing your face made out of chocolate? Done. All you need is a 3-D printer!
The possibilities of 3-D printing seem endless. All the user has to do is to design(设计) an object on the computer and choose a material(材料) to print in. The printers print in hundreds of different materials including glass, sugar and even skin! When the user presses “print”, the 3-D printer spreads the material layer(层) by layer and like magic the object is produced.
The first 3-D printer was invented in 1986 by an American, Charles Hull. But 3-D printing has only become cheap enough recently for most people to use. Designers now use 3-D printing to create unusual things. The Dutch artist Dirk Vander Kooj prints furniture made from old fridges. And doctors have used 3-D printing to print human body parts! The Telegraph reported in February that scientists from Cornell Medical College even printed a man-made ear.
But like a lot of new technologies, if 3-D printing gets into the wrong hands, it can be dangerous. In 2011 a group of four men in the US used 3-D printing to produce ATM skimmers (提款机盗刷器). These were placed on an ATM and stole over $400,000 from users of the ATM. It is terrible to think that criminals like them might one day use a 3-D printer to print a gun.
But for better or for worse, 3-D printing has been put into use. In a few years, you’ll probably be wondering how you could ever live without your 3-D printer!
_______ invented the first 3-D printer.
| A．Charles Hull | B．Dirk Vander Kooj |
| C．A doctor called Cornell | D．Four men in the U.S |

a. Choose a proper material.
b. Press the print button.
c. The 3-D printer spreads the material.
d. Use a computer to design an object.
| A．a-b-c-d | B．d-a-b-c |
| C．a-c-d-b | D．d-c-b-a |
