Article: From furniture to jewelry, from the medical industry to civil engineering,three--dimensional printing can turn all sorts of ideas into objects. "I wanted to print large objects such as buildings,"said Behrokh Khoshnevis,professor of the University of Southern California.He planned to construct a house in 24 hours by applying 3D printing techniques,but he admitted there would be difficulties in meeting his goal. "For example,if you run out of ink while printing on paper,you will throw that paper away.But you cannot throw half completed buildings away if your material gets stuck,"he said.Although the printed house is not available to visit,there is a chance for people in Shanghai to see items printed in 3D. The Belgium-based company Materialize NV is currently holding a 3D printing exhibition in Shanghai that started in late 2012 and will continue until the middle of this year.The company is eager to show Asia what is possible with 3D printing. "All the pieces shown here are what cannot be made through traditional techniques. A good example of this customization is hearing aids More than l0 million people already use 3D printed hearing aids.all made according to the size of their ear."said Wim Michiels, executive vice-president at Materialise NV. "You can produce anything whenever and wherever you like.You don't need to set-up production lines for pieces that only need a limited amount of product.Setting up a production Line is a tot of work, takes a long time and is very expensive for a limited number of pieces" said Michiels. Kim Francois,managing director of Matcrialise China,said their European and American clients have at ready made the next step toward additive manufacturing with small-series production such as hearing aids. Question: According to Khoshnevis,what is the main difficulty in printing buildings? - Time. - Technique. - Space. - Material.

Read the following article and select the best answer. Article: It would be pleasant to believe that all young girls in the past got married for romantic reasons; but the fact is that many of them regarded marriage as their only chance to gain independence from their parents, to have a provider, or to be assured of a good place in society. A couple of generations ago, an old maid of twenty-five did not have much to look forward to, she was more or less fated to remain with her parents or to live in some relative's home where she would help with the chores and the children. Not so any more. In the first place, women remain young much longer than they used to, and an unmarried woman of twenty-eight or thirty does not feel that her life is over. Besides, since she is probably working and supporting herself, she is free to marry only when and if she chooses. As a result, today's women tend to marry later in life. They have fewer children-or none at all--if they prefer to devote themselves to their profession. The result is a decline in the birthrate. The new role that women have developed for themselves has changed family life. Children are raised differently; they spend more time with adults who are not their parents: baby sitters, day-care center personnel, relatives, or neighbors. Whether they gain or lose in the process is a hotly debated question. Some child experts believe that young children must spend all their time with their mother if they are to grow sound in body and mind. Others think that children get more from a mother who spends with them "quality time" (a time of fun and relaxation set aside for them) rather than hours of forced and unhappy baby sitting. And many child psychologists point out that children kept in day-care centers every day are brighter than those raised at home. No matter what it is, one thing about child-raising to be certain of is that the longer the child is with the mother, the better. Question: It can be concluded from the passage that _ . - women today have developed a new role in family life - the birthrate is declining as a result of women's pursuit of careers - women have always been dependent on their parents even after marriage - children must spend all their time with their mother if they are to grow sound
(Answer)
the birthrate is declining as a result of women's pursuit of careers

Ques:Read the following article and select the best answer. Article: Not everyone can sit around and daydream while twirling hair or worrying about how they are going to style it for school pictures or a special event. Some kids have no hair at all due to illness. Locks of Love is an organization that helps kids deal with their hair loss by providing real hair wigs from donors. Jessica Moon, a photo editor, donates her hair whenever she cuts it, waiting each time for it to grow the necessary 10 inches. "I don't miss my hair at all," Moon said. "And it grows really quickly." At Locks of Love, the focus is on helping kids who have gone bald and feel embarrassed to go out in public to go on with the activities they normally enjoy. Lauren Kukkamaa, who works for the organization, believes that it is important for kids to live out their lives as normally as possible. "Many times, a lot of children feel embarrassed by their baldness, " she said. "They have low self-confidence, so they may want to stop playing sports or going to summer camps. When they get the hair wigs, they feel confident to start doing these things again." "For a donor, I think it's a very personal donation," said Kukkamaa. "You're giving of yourself. If you're looking for a way to get involved and give back, I think it's a great opportunity for someone." Moon, who first donated her hair when she was 15 after she found out her father had cancer, said donating is a good way to make a difference. "The best part is that it's helpful for someone and it does make a difference for patients who need the hair," she said. Question: According to the text, Kukkamaa thought that _ . - 10 inches of hair may change a child's life - people are devoting themselves by donating hair - a person with long hair will be more confident - children like wearing wigs for a special event

Ans:
people are devoting themselves by donating hair
