Imagine having an idea, drawing it on paper, bringing it to a store and seeing it turned into a
physical object. This is now possible with the help of 3D printers. Such machines were once used just
by universities and big companies, but now, stores with 3D printing services are appearing around the
United States.
Bryan Jaycox and his wife opened The Build Shop LLC in Los Angeles two years ago. The store
is filled with tools like a laser cutter, an industrial sewing machine and 3D printers. The Jaycoxs offer
3D printing classes and services for anyone who is interested.
"I think 3D printing is going to be huge. It's going to have a huge effect on society as a whole."
One of the students in a recent class was KiChong Tran. He plans to open a 3D printing business in
Cambodia.
3D printing services are becoming available for American consumers.
The UPS Store is a nationwide retailer (零售商 ) that provides shipping, copying and other
services. The UPS Store recently put 3D printers in three of its independently-owned stores. Burke
Jones owns one of the stores in San Diego.
"The demand has been amazing. It's been much more than I would have imagined." The UPS
Store plans to add 3D printers in three more stores.
At The UPS Store, the cost of the object depends on the amount of materials used. The store
charges up to $95 an hour to design the object with computer software that creates a digital file to
guide the printer.
Mr. Jaycox predicts that within five years, 3D printing technology could become more popular.
But KiChong Tran says even current technology can make a difference in a developing country like
Cambodia.
"With 3D printing, you can give them tools; you put it in their hands so they are responsible
more for their own development and they learn skills beyond just learning English and becoming a
tour guide or something like that or working at a bank; you can actually create things that give value
to the world."
He says it's not just in Cambodia but anywhere where there is a 3D printer that it can turn a good
idea into reality.

My 17-year-old daughter went off to college and having her away from home brought back memories of watching Peter Pan when she was little. In the classic TV production, one scene in particular impressed me: when Mrs. Darling puts her children into bed. As she turns off the last of the night light, she takes one last look at the bedroom and says, “Dear night lights, protect my sleeping children.” As a mother, I know how much she loves her children.
It has been several weeks since we took our daughter to college and she seems to be adjusting well after a short period of homesickness. For us, though, it’s another story. Like most parents, I love checking in on my children at night. But now she’s gone, and I find night times the hardest. I miss her most at night.
In my neighborhood, most of the parents whose kids are off to college are dealing with similar melancholy. My husband is filled with anxiety. One friend talked about getting this sick feeling in her stomach as she prepared for the college drop-off. We complained that many of us were too busy to truly enjoy being with our children while we had them.
For us moms, seeing Toy Story 3 only made the sadness worse as we watched the character Andy, who is the same age as our kids, say goodbye to his childhood as he prepares to leave for college. And it’s not just “first-time” parents like me. Two moms who have kids already well into college said the separation didn’t get any easier. “You feel like something has been taken away from inside you” said one of them.
I imagine things will get easier with time, especially as I see my daughter adjust to college life. Meanwhile, as I keep my cell phone close to me in bed and text my daughter goodnight and sweet dreams every night, I like to think that messages serve as a night light that keeps her safe.
1.The writer was deeply impressed by the scene in Peter Pan because ________.
A. the scene showed a mother’s deep love for her children
B. the scene was very exciting and interesting
C. the scene taught her and her daughter a good lesson
D. she watched the scene with her daughter
2.After her daughter went to college, the writer ________.
A. realized she hadn’t done enough for her daughter
B. often cried as she missed her daughter so much
C. didn’t get used to the change for a long time
D. failed to have a good sleep every night
3.What is the underlined word “melancholy” in Paragraph 3 similar in meaning to?
A. Happiness. B. Anger.
C. Excitement. D. Sadness.
4.According to the last paragraph, why did the writer keep her cell phone close to her in bed?
A. To call her daughter any time.
B. To wait for her daughter’s calls.
C. To wait for her daughter’s messages.
D. To say good night to her daughter.

Is beauty something always positive? Almost everyone thinks attractive people are happier and healthier, have better marriages and have more respectable jobs. Personal advisors give them better advice for finding jobs. Even judges are softer on attractive defendants. But in the executive(主管的) circle, beauty can become a disadvantage.
While attractiveness is a positive factor for a man on his way up the executive ladder, it is harmful to a woman. Handsome male executives were considered having more honesty than plainer men; effort and ability were thought to lead to their success. Attractive female executives were considered to have less honesty than unattractive ones; their success was connected not with ability but with factors such as luck.
All unattractive women executives were thought to have more honesty and to be more capable than the attractive female executives. Why are attractive women not thought to be able? An attractive woman has an advantage in traditionally female jobs, but an attractive woman in a traditionally manly position appears to lack the manly qualities required.
This is true even in politics, “When the only clue is how he or she looks, people treat men and women differently, ” says Anne Bowman, who recently published a study on the effects of attractiveness on political candidates(候选人). She asked 125 college students to rank two groups of photographs, one of men and one of women, in order of attractiveness. The students were told the photographs were of candidates for political offices. They were asked to rank them again, in the order they would vote for them.
The results showed that attractive males completely defeated unattractive men, but the women who had ranked most attractive unchangeably received the fewest votes.
1. In traditionally female jobs, attractiveness ________.
A. makes women look more honest and capable
B. strengthens the manly qualities required
C. often enables women to succeed quickly
D. is of no importance to women
2.Bowman’s experiment shows that when it comes to politics, attractiveness _____.
A. turns out to be a disadvantage to men
B. has as little effect on men as on women
C. affects men and women alike
D. is more of a disadvantage than an advantage to women
3.According to the passage, people’s views on beauty are often _____.
A. practical B. one – sided
C. old fashioned D. supportive
4. The passage is mainly about _____.
A. the advantages of being attractive
B. the disadvantages of being attractive
C. equal rights for women
D. the importance of appearance

Are you an optimist? Do you look at your glass and see it as half full? Do you believe that every cloud has a silver lining and that generally things turn out for the best? Do you believe that if something is meant to be, it will be? If you reply “yes” to all of these questions, then you are an optimist. You probably are enthusiastic, cheerful and outgoing. You may well be successful at work and in love.
But you may be misguided because things don’t turn out for the best. You may believe that when one door closes another one opens (for example, you may fail to obtain a new job, and another chance will come around soon). Wrong. When one door closes, another door slams in your face. That’s bitter reality.
Now a book has been published which confirms what we pessimists (悲观者) have suspected all along. It’s called The Positive Power of Defensive Pessimism. Its author argues that defensive pessimism can lead to positive results. Defensive pessimism is a strategy used to manage fear, anxiety and worry. Defensive pessimists prepare for things by setting low outcomes for themselves. They carefully consider everything that may go wrong and plan for ways to handle these problems. And this gives them a sense of control. Lawrence Sanno, a psychology professor, says, “What’s interesting about defensive pessimists is that they tend to be very successful people, so their low opinion of the situation’s outcomes is not realistic. They use it to motivate themselves to perform better. ”
So far, so good. This is not rocket science. Defensive pessimists prepare carefully and consider what might go wrong, whether at work, on a date or even in a sports game. It makes sense to have a back-up plan. There are many sayings in English urging caution. For example, “Don’t put all your eggs in one basket,” and “Don’t count your chickens until they hatch.” To have a confident and optimistic approach to life’s problems is good. But listen to what Woody Allen, the American comedian says, “Confidence is what you have before you understand the problem.”
There are pros and cons of being an optimist and a pessimist. Don’t feel bad if you see the glass half empty. You are a realist. But lighten up and hook up with someone who sees the same glass half full.
1. The writer would probably describe himself as ________.
A. a realist B. a scientist
C. an optimist D. an artist
2.Defensive pessimists are likely to make use of ________ to help achieve success.
A. the final outcome B. their low opinion
C. people’s motivation D. their performance
3.The underlined sentence “This is not rocket science” in Paragraph 4 means “________”.
A. it is out of the question
B. it is quite simple to understand
C. it is far beyond reach
D. it is not a worthwhile thing to do
4. Which of the following English expressions would a defensive pessimist probably believe?
A. “Every cloud has a silver lining.”
B. “Whatever will be, will be.”
C. “Don’t put all your eggs in one basket.”
D. “The glass is half full not half empty.”
