Many people say pennies are not worth saving. After all, a penny is only worth a cent. But one unusual penny turned out to be worth a lot more when a coin collector paid $1.7 million for it earlier this month.
The coin is one of a kind. It is the only penny that the Denver mint(铸币厂) made out of copper, instead of steel, in 1943. Because it is unique, it is also very valuable. No penny has ever sold for so much money.
The Changing Penny
The Lincoln penny first appeared in 1909. For 34 years, the one-cent coin was made out of copper. Then, in 1943, the penny changed. World War II was going on, and copper was needed for equipment. So for one year, pennies were made out of steel instead. At least most of them were.
Only a few coins were made out of unused copper. There are three main mints, or places where coins are made, in the United States. Of the known copper pennies from 1943, twelve were made in the Philadephia mint, and five were made in the San Francisco mint. Only one was made in the Denver mint.
Nobody knows for sure why a copper penny was made at the Denver mint in 1943, coin dealers Andy Skrabalak told Time for Kids. “There is a rumor that a mint employee made the coin in the middle of the night.”
A Special Set
The coin collector who bought the $1.7 million penny wants to remain unknown. But the reason for the trade is known. He already had two copper pennies from 1943 – one from the San Francisco mint and one from the Philadephia mint. To complete the set, he needed the Denver penny. The three coins will go on display at a coin exhibition in Tampa, Florida.
The collector who sold the penny is also keeping his name a secret. It took four years to convince him to give up the rare coin. Now that he has finally donating all of the money to charity.Why is the Lincoln penny worth over one million dollars?
| A．Because it has a history of thirty-four years. |
| B．Because it was made out of a rare material. |
| C．Because it was made on one night of 1943 by the Denver mint. |

It’s not easy being a teenager---nor is it easy being the parent of a teenager．You can make your child feel angry, hurt or misunderstood by what you say without realizing it yourself．It is important to give your child the space he needs to grow while gently letting him know that you’ll still be there for him when he needs you．
Expect a lot from your child, just not everything．Except for health and safety problems，such as drug use or careless driving, consider everything else open to discussion．If your child is unwilling to discuss something, don’t insist he tell you what’s on his mind．The more you insist，the more likely that he’ll calm up．Instead, let him attempt to solve things by himself．At the same time, remind him that you’re always there for him should he seek advice or help．Show respect for your teenager’s privacy（隐私）．Never read his mail or listen to personal conversations．
Teach your teenager that the family phone is for the whole family．If your child talks on the family’s telephone for too long, tell him he can talk for l5 minutes, but then he must stay off the phone for at least all equal period of time．This not only frees up the line so that other family members can make and receive calls, but teaches your teenager moderation（节制）．Or if you are open to the idea, allow your teenager his own phone that he pays for with his own pocket money or a part-time job．
The main purpose of the text is to tell parents_________．
| A．how to get along with a teenager |
| B．how to help a teenager grow up |

The term, culture shock, describes the anxiety produced when a person moves to a completely new environment. This term expresses the lack of direction, the feeling of not knowing what to do, and not knowing what is appropriate or inappropriate. The feeling of culture shock generally sets in after the first few weeks of coming to a new place.
We can describe culture shock as the physical and emotional discomfort one suffers when coming to live in another country or place. Often, the way that we lived before is not accepted as or considered as normal in the new place. Everything is different, for example, not speaking the language, not knowing how to use banking machines and so forth.
Although one can experience real pain from culture shock, it is also an opportunity for resetting one' s life objectives. It is a great opportunity for learning and acquiring new viewpoints. Culture shock can make one develop a better understanding of oneself.
Culture shock has many stages. The first stage is called the "honeymoon" stage. The new arrival may feel excited as everything is new.
In the second stage, a person may encounter some difficult times in daily life. For example, communication difficulties may occur such as not being understood. There may be feelings of discontent, anger, sadness, and feeling incompetence. This happens when a person is trying to adapt to a new culture. Transition (过渡) between the old methods and those of the new country is a difficult process and takes time to complete.
The third stage is characterized by gaining some understanding of the new culture. One may start to feel a certain psychological balance. The new arrival may start to have a feeling of direction and want to belong.
In the fourth stage, the person realizes that the new culture has good and bad things to offer. The person has a more solid feeling of belonging and starts to set goals for living.
The fifth stage is called the " re-entry shock". This occurs when a return to the
country of origin is made. One may find that things are no longer the same. For example, some of the newly acquired customs are not in use in the old culture.
Many factors (因素) contribute to the length and effects of culture shock. For example, the individual's state of mental health, type of personality, previous experiences, familiarity with the language, and level of education. So the five stages are present at different times and each person has their own way of reacting.
The main purpose of the passage is to________
| A．discuss and clarify | B．argue and advise |
| C．introduce and explain | D．compare and evaluate |
While astronauts in space get to do many exciting things, they miss out on ordinary things that we all take for granted—being able to walk on firm ground, hanging out with family and digging into a slice of hot steaming pizza. Though not much can be done about the first two things, there may soon be a solution to the third one, thanks to this cool 3-D pizza printer!
About a year ago, NASA offered $125 ,000 to Anjan Contractor, a 3-D technology expert, to build a device (设备) that would allow astronauts to make pizza on demand. The mechanical engineer promised that his invention would produce pies in large quantities that looked, tasted and even smelled like pizza made in common ovens.
Late last year, the engineer presented a video of his first prototype (原型) that begins by creating a single slice of dough (面团) that is cooked and printed at the same time. Then comes the tomato “sauce” — a mix of tomato powder, oil and water and finally, a protein slice that resembles cheese. While the video doesn’t show the baking process, the inventor says that once the pizza is printed, it can be ready to be consumed in 7 seconds.
While the pie in the video looks delicious enough to attract any pizza lover, Anjan Contractor is far from ready for astronauts. That’s because he still has to find a solution to make the food container in the printer last for 30 years. Though that may sound unrealistic, actually it is not.
Anjan Contractor believes that the only way that is possible is that the water is removed from all the ingredients (配料) and then they are reduced to the powder form. This, as you can imagine, will not be so easy. But, while the printer may not be ready for space, it certainly looks ready enough for people on earth. Hopefully, NASA and Contractor will consider selling it to those not fortunate enough to go to Mars!
What’s the best title of the passage?
| A．NASA is trying its best to help astronauts eat better |
| B．Astronauts may soon be able to enjoy steaming hot pizza |
| C．NASA is working on making pizza for common people |
| D．A 3-D pizza printer has been used to make pizza |
Most of us spend our lives seeking the natural world. We go fishing, sit in the garden, have a picnic, live in the suburbs or go to the seaside. The most popular leisure activity in Britain is going for a walk. When joggers jog, they don’t run the streets. Every one of them tend to go to the park or the river.
But despite this, our children are growing up nature deprived(剥夺). I spent my boyhood climbing trees. These days, children are robbed of these ancient freedoms, due to problems like crime, traffic, the loss of the open spaces and strange new ideas about what is best for children, that is to say, things that can be bought, rather than things that can be found.
The truth is to be found elsewhere. A study in the US: families had moved to better housing and the children were assessed for ADHD—attention deficit hyperactivity disorder (多动症). Those whose accommodation had more natural views showed an improvement of 19%; those who had the same improvement in material surroundings but no nice view improved just 4%.
ADHD is one of the great problems of modern childhood. One study after another indicates that contact with nature gives huge benefits to ADHD children. However, we spend money on drugs rather than on green places.
The life of old people is measurably better when they have access to nature. The increasing concern for the growing population of old people is in quality rather than quantity of years. And study after study finds that a garden is the single most important thing in finding that quality. Even problems with crime and aggressive behaviour are reduced when there is contact with the natural world.
We need the wild world. It is essential to our well-being, our health and our happiness.
What is the main idea of this passage?
A. Access to nature improves our life.
B. Nature treats children with ADHD.
C. Getting close to nature reduces crime.
D. Man can’t live without natural areas.
When there are some strangers in front of us, which of them will we trust?
According to a new study in the online PLOS One, people make their decisions to trust others largely based on their faces．Your appearance can do a lot for you, especially if you are in the financial industry．The more trustworthy you look, the more likely people will buy what you’re selling．
Researchers from Britain’s University of Warwick Business School, University College London, and Dartmouth College, US, did a number of experiments．
The research team used computer software to make 40 faces, from the least to the most trustworthy-looking．
The study said that the difference between a trustworthy face and one that isn’t as trustworthy comes from features that look slightly angry or slightly happy, even when the face is at rest．However, a slightly happy face is more likely to be trusted．
Researchers gave participants some money and asked them which face they trusted to invest the money for them．Then researchers gave some good and bad information about the people with these faces, and asked the participants again whom they trusted．
The results showed that even if they got different information, the participants didn’t change their choices．They were still more likely to invest their money with the more trustworthy-looking faces．
Chris Olivola, one of the study’s authors, said in the University of Warwick’s press release: “It seems we are still willing to go with our own instincts about whether we think someone looks like we can trust them．The temptation to judge strangers by their faces is hard to resist．”
Which of the following can be a proper title for this passage?
| A．What kind of face do you trust? |
| B．Who did the experiments? |
| C．Why do you trust him or her? |
| D．Why did they do the experiments? |
