Mothers and daughters go through so much--yet when was the last time a mother and daughter sat down to write a book together about it all? Perri Klass and her mother, Sheila Solomon Klass, both gifted professional writers, prove to be ideal co-writers as they examine their decades of motherhood, daughterhood, and the wonderful ways their lives have overlapped . Perri notes with amazement how closely her own life has mirrored her mother's: both have full-time careers; both have published books, articles, and stories; each has three children; they both love to read. They also love to travel--in fact, they often take trips together. But in truth, the harder they look at their lives, the more they acknowledge their big differences in circumstance and basic nature. A child of the Depression , Sheila was raised in Brooklyn by parents who considered education a _ for girls. Starting with her college education, she has fought for everything she's ever accomplished. Perri, on the other hand, grew up privileged in the New Jersey suburbs of the 1960s and 1970s. For Sheila, wasting time or money is a crime, and luxury is unthinkable while Perri enjoys the occasional small luxury, but has not been successful at trying to persuade her mother into enjoying even the tiniest thing she likes. Each writing in her own unmistakable voice, Perri and Sheila take turns exploring the joys and pains, the love and bitterness, the minor troubles and lasting respect that have always bonded them together. Sheila describes the adventure of giving birth to Perri in a tiny town in Trinidad where her husband was doing research fieldwork. Perri admits that she can't sort out all the mess in the households, even though she knows it drives her mother crazy. Together they compare thoughts on bringing up children and working, admit long-hidden sorrows, and enjoy precious memories. Looking deep into the lives they have lived separately and together, Perri and Sheila tell their mother-daughter story with honesty, humor, enthusiasm, and admiration... Why does Perri think that her own life has mirrored her mother's? A) They both have gone through difficult times. B) They have strong emotional ties with each other. C) They have the same joys and pains, and love and bitterness. D) They both have experiences as daughter, mother and writer.

In a unique research cooperation between Stratasys, Education, R&D departments and MIT's Self-Assembly Lab, a new process is being developed, known as 4D Printing. The 4D printing concept, which allows materials to "self-assemble " into 3D structures, was initially proposed by Massachusetts Institute of Technology faculty member Skylar Tibbits. Tibbits and his team combined a strand of plastic with a layer made out of "smart" material that could self-assemble in water. They advanced this concept by creating materials that can change into several different complicated shapes, though this kind of material remains the bottleneck of 4D technology. To many people that are just starting to get used to the idea of 3D printers, the name 4D is causing confusion because they cannot understand where this fourth "dimension" coming from. 4D technology shares many of the same principles of 3D printing and is essentially still about creating a new, 3D structure out of certain component; however, Tibbits states the fourth dimension at work here comes from concept of the fourth dimension of time. The difference between these 3D and 4D creations is that these new forms have the ability to transform and adapt over time. 4D printing works through self-assembly -- a system where "disordered elements form an "ordered" structure via an interaction. With these 4D printed materials, these disordered materials are strands or sheets of specially designed materials. Environmental changes then stimulate a response from them so that they form a preprogrammed shape. The idea of having adaptable technology that only relies on energy and non-human interactions raises some interesting questions about where 4D printing can be used and the practical applications in dangerous environments. This could mean improved infrastructures in extreme conditions, leading to a reduced need for workers to put themselves at risk, but the potential goes even further than that. The technology promises exciting new possibilities for a variety of... What does the passage lead you to believe? A) 4D printing will take the place of 3D printing in the near future. B) Most aspects of our daily life can be affected by 4D printing. C) 4D printing will benefit humans by saving labor somehow. D) Smart materials can be transformed into other types of material.

Ques: The Barcelonabased architects of the Galactic Suite Space Resort say it will cost $4.4 million for a threenight stay at the hotel. This price also includes an eightweek training course on an island. During their stay, guests would see the sunrise 15 times a day and travel around the world every 80 minutes. Galactic Suite Ltd's CEO Xavier Claramunt says the project will put his company in a leading position of a new industry with a huge future ahead of it, and forecasts space travel will become common in the future. "It's very normal to think that your children, possibly within 15 years, could spend a weekend in space" he told Reuters Television. A promising space tourism industry is beginning to take shape with construction in progress in New Mexico of Spaceport America, the world's first facility built specifically for passengers. British industrialist Richard Branson's space tours firm, Virgin Galactic, will use the facility to send tourists to space at a cost of $200,000 a ride. Galactic Suite Ltd, set up in 2007, hopes to start its project with a single pod in orbit 280 miles above the earth. "It will take a day and a half to reach the pod, and the passengers will join it for three days," Claramunt said. More than 200 people have expressed an interest in traveling to the space hotel and at least 43 people have already reserved it. The numbers are similar for Virgin Galactic with 300 people already paid or signed up for the trip, but unlike Branson, Galactic Suite says they will use Russian rockets to transport their guests into space from a spaceport to be built on an island in the Caribbean. But critics have questioned the project, saying the length of time that will be used is unreasonable and also where the money is coming from to support the project. What's Xavier Claramunt's attitude towards the space tourism industry? A) Quite critical. B) Slightly worried. C) Highly optimistic. D) Fully satisfied.
Ans: C
Children lie on couches or sit on floors, nearly hypnotized by all kinds of messages coming from the television. This scene has become all too familiar. Increasingly, young children are adopting a watching-TV lifestyle, at s stage in life when activity is important to their growth. Furthermore, family time is being destroyed by too much TV time. Here are some facts you need to know: *Research shows that children spend between five and six hours per day watching TV, and they go to bed before having any communication with other family members. *Time spent in front of a screen is reducing the amount of time children spend sleeping. *The more time a youth spends in front of a screen, the more likely he or she is to be overweight. Experts offer the following advice to parents on how to stop their children from becoming addicted to television: *Do not put a TV in a child's bedroom. *Make meal time, family time -----turn off the TV during a family meal time. Better yet, remove the TV from the eating area. *Make TV time active time by doing simple exercise during advertisement breaks. *Help your kids be clever TV watchers by teaching them to recognize a sales trick in advertisements . *Create family memories by planning fun activities instead of always watching TV with your family. * _ . Limit your own TV watching to less than two hours per day. The best way to learn is to follow; this is especially true for children. Which fact is not mentioned as a result of watching TV in this passage? A) Family time has been destroyed. B) Children who watch too much TV are often overweight. C) Children spend less time sleeping because of watching TV. D) Children's study can be badly influenced if they watch too much TV.
