An Israeli surgeon's dexterity  treating the largest and most serious wounds has brought him to Sichuan province again and again, he tells Liu Zhihua. Moris Topaz, head of the plastic surgery unit of the well-known Hillel Yaffe Medical Center in Hadera, Israel, finally had a good sleep on the flight from New York to China recently. The 63-year-old usually sleeps only three hours a day but that's enough, he says, to give him plenty of energy for his work. On this, his most recent trip to China, he was part of a delegation led by Ronni Gamzu, director-general of Israel's Ministry of Health, which aimed to strengthen the cooperation of health communities in the two countries. While "cooperation" may sound vague to outsiders, Sichuan resident Gong Fangxue has a very clear idea what that word means to ordinary people. If not for TopCloser, a groundbreaking method for closing large wounds that Topaz applied in her operation, Gong probably would have died from a huge fatal tumor. "It was a unique case over a very big tumor. Usually with these kinds of tumors, we have to do complicated surgeries with skin grafts or flaps," Topaz says. "This time, we actually stretched the skin in a way we hadn't done before." Gong, 40, found a suddenly fast-growing bump on her right shoulder in 2009. The resident of Deyang was diagnosed with a fatal spindle cell tumor. Although it didn't spread to other parts of the body, the cancerous bump grew very fast. Over the next two years, Gong underwent several removal surgeries, but the condition always recurred shortly after the treatments, and the tumor grew bigger and bigger. Late last year, Gong came to the People's Hospital of Deyang City, after many other hospitals, including big ones in Beijing, refused to treat her. By that time, the tumor had become half as big as Gong's head, making her head lean toward the left. It had become difficult for her to move her neck. Worse, the tumor stretched the skin so far that at any time, the blood vessels could be broken, potentially leading to... All the following contribute to the successful surgery on Gong Fangxue except   _  . A) the medical method of TopCloser B) the diagnosis of the disease in 2009 C) the superb experience and skills of Topaz D) the cooperation between the Israeli and Chinese doctors

Technological change is everywhere and affects every aspect of life, mostly for the better. However, social changes are brought about by new technology are often mistaken for a change in attitudes. An example at hand is the involvement of parents in the lives of their children who are attending college. Surveys   on this topic suggests that parents today continue to be "very" or "somewhat" overly-protective even after their children move into college dormitories. The same surveys also indicate that the rate of parental involvement is greater today than it was a generation ago. This is usually interpreted as a sign that today's parents are trying to manage their children's lives past the point where this behavior is appropriate. However, greater parental involvement does not necessarily indicate that parents are failing to let go of their "adult" children. In the context   of this discussion, it seems valuable to first find out the cause of change in the case of parents' involvement with their grown children. If parents of earlier generations had wanted to be in touch with their college-age children frequently, would this have been possible? Probably not. On the other hand, does the possibility of frequent communication today mean that the urge to do so wasn't present a generation ago? Many studies show that older parents - today's grandparents - would have called their children more often if the means and cost of doing so had not been a barrier. Furthermore, studies show that finances are the most frequent subject of communication between parents and their college children. The fact that college students are financially dependent on their parents is nothing new; nor are requests for more money to be sent from home. This phenomenon is neither good nor bad; it is a fact of college life, today and in the past. Thanks to the advanced technology, we live in an age of bettered communication. This has many implications well beyondthe role that parents seem to play in the lives of their children who have left for... The writer believes that   _  . A) parents today are more protective than those in the past B) the disadvantages of new technology outweigh its advantages C) technology explains greater parental involvement with their children D) parents' changed attitudes lead to college children's delayed independence

*Question*
The future of agriculture must achieve several goals at the same time.  First, it now appears that we will have to double world food production in the next 40 years due to population growth, increasing meat consumption and pressure from biofuels  . We will also have to reduce the environmental impacts from our farming practices, which have caused widespread damage to soils, ecosystems, waters and even the atmosphere. In fact, agriculture's impacts are as bad as climate change as an environmental concern. Besides, we will have to improve food security for the world's poor. While the Green Revolution of the 1960s made it possible to feed hundreds of millions more people than in earlier eras, the number of the under-nourished in the world has started to rise again. Finally, we will have to increase the recovering ability of agriculture from shocks. Today, our high-efficiency, globalized world has many benefits, but it is vulnerable   to destruction, whether from droughts, diseases or sudden price rises. We must start building better food systems to better keep us away from future shocks. Currently, there are two models of agriculture: local and organic agriculture vs. globalized and industrialized agriculture. Each has been strongly supported and severely criticized, but neither of these models, standing alone, can fully meet our needs. Organic agriculture teaches us important lessons about soils, nutrition and pest management. Unfortunately, organic food provides less than 1% of the world's calories, mostly to the wealthy. It is hard to imagine organic farming developing to feed 9 billion. Globalized and industrialized agriculture has benefits of high output and low labor demands. Without it, billions of people would have starved. However, it has come with enormous environmental and social costs, which cannot be sustained. Rather than voting for just one solution, we need a third way to solve the crisis. Let's take ideas from both sides, creating new, hybrid solutions that increase production, save resources... We can learn from the passage that   _  . A) everyone can afford to enjoy organic food at will B) we will vote to decide which farming system to take C) the writer is quite optimistic about future agriculture D) only experts can find a better agricultural solution
