Plant cloning has been an agricultural technique used by farmers and gardeners for centuries. Grafting is a common form of plant cloning. Many plants in nature actually clone themselves and reproduce asexually. Cloned plants are much more predictable than normal plants, so their yield is more reliable. Cloned plants also reproduce faster, limiting the amount of time between planting and harvesting. It is also often cheaper to produce seeds through cloning than through traditional methods. Plants can essentially be optimized so that farmers or individual growers always have the best seeds available. With more yield at a faster rate, farms can produce more food for more people while decreasing overall costs. Cloning can be used to wipe out diseases that previously killed off entire fields of crops. This would make plants immune to the kinds of diseases that farmers and gardeners around the world fear each year. Crop failures due to disease and virus could become a thing of the past. Also, plants that are near extinction can be brought back to life through cloning. Through cloning scientists can develop "super" fruits and vegetables of superior nutritional quality. This could make for a healthier population overall. This is already being done through selective pollination , and genetic cloning could take it to the next level. By plant cloning we have a population of identical plants and all these plants equally suffer from the same diseases, but in nature the weak would die and the strong would survive. While there are some dangers to consider with plant cloning, there are plenty of benefits that could prove vital to the propagation of the human species. According to the text, cloned plants_. A) have lower yield than normal plants B) need little care from people C) resist various kinds of diseases D) have a short growth cycle

It took me more than 10 years to realize that the world has no shortage of fashion designers who have the ability to make trendy and elegant garments, but that it is badly in need of, simply, clothes designers. My own definitions would set fashion and clothing greatly apart. It is a fact that, in the shopping malls, there are plenty of beautiful garments whose unpredictability makes our life color1ful and interesting. You are almost convinced: You can buy whatever you dare to think. There is no doubt that fashion designers are usually with high qualifications. They study fashion trends, select color1s, and make sure the final production of their designs is done properly. However, as experience grew with age, my attraction to arts became ever stronger. I have a strong desire for clothing to stand as does paint to the painter, as does stone to the sculptor, as a simple and particular language of an individual creation, which draws the audience from an appreciation of the surface to deeper thoughts with the world of the soul. I believe that the most meaningful creative motives should arise through caring for other people, the great care of humanity--a concern for human feeling and spirituality. _ , but it is bigger than love, and it is unconditional. I believe the greatest works of art can touch the deepest and strongest parts of human feelings and the world of the spirit, and only these works can be the memories of history, preserving the most valuable feelings that have ever existed, and inspiring a greater awareness of ourselves. I am not satisfied if people only appreciate clothing if it merely satisfies their desire. I believe clothing could be a specific creative language for communicating ideas and thoughts, for inspiring you and shaping your behavior. Those clothes fashioned out of necessity possess a power that can continue to exist across the ages. This is what I have tried to achieve, the clothing to return to its original simplicity, the clothing to help people regain the natural sense. The true... The writer indicates that the primitive clothes are made as a result of _ . A) respect for nature B) spiritual value C) necessity D) simplicity

Q: A man enters a store to buy milk. He walks out of the store with milk. That is all--milk. At the same time, a woman enters the same grocery store also to buy milk. She buys it. But, she also buys chicken and lemons to make dinner that night. She also gets a bottle of wine for drinks with friends and a birthday card for her husband's niece. And that is the difference between the female and male brains simply explained in a grocery store. Generally speaking, men do one thing at a time. Women do many. Doing many things at one time is often called "multi-tasking," a very popular word these days. Now scientific research supports this theory about male and female brains. A recent study has confirmed what we have known all along--men and women think differently. Scientists at the University of Pennsylvania studied brain images of 949 people aged from 8 to 22 years old. They found that male brains have more connections on one side of the brain, or hemisphere. In the female brain, they found more activity and connections between the right and left sides of the brain. The left side of the brain is known as the side of "reason". The right hemisphere is known as the "creative" side. Regina Verma is a professor at the University of Pennsylvania. She co-wrote the report. She says when women are asked to do something complicated they might use different parts of the brain. But men generally use just one. As a result, men generally deal directly with a problem. There is a strong connection between the "understanding" and the "action" parts of their brains. Women, however, might include other parts of the brain, like the part connected with "reason" and the part connected with sensitivity when solving a problem. Women take a less direct path to find a solution. Thanks for your listening. I'm your announcer Anna Matteo. Where does this passage probably come from? A) A textbook. B) A newspaper.

Q: China needs to set absolute restrictions on greenhouse gas emissions if it is to fulfill its aim to set up a carbon market over the next five years, a cabinet office think tank said in a paper. "It is only under an absolute emissions cap that carbon emission permits will become a scarce resource and possess the qualities of a commodity," the State Council"s Development and Research Center said in a paper in Seeking Truth, a magazine published by the ruling party. China has traditionally baulked at the idea of emissions caps either on a regional basis or for industrial sectors, invoking a key Kyoto protocol principle that puts most of the burden of cutting green-house gases on developed countries. China, the world 's biggest emitter of greenhouse gases, has also been under external pressure to make stronger commitments in the battle against global warming .The country has been the biggest beneficiary of the Clean Development Mechanism, a UN-backed scheme that allows industrialized countries to meet their CO2 reduction targets by purchasing certified emission reductions or CERs from low-carbon projects launched in developing nations. However, the European Union, the biggest buyer of CERs, has said it will not accept CERs generated by Chinese projects once the first phase of its Emissions Trading Scheme ends in 2012, though projects already registered will remain valid. China agreeing to limit emissions now because _ A) they care about the environment B) emissions harm people's health C) of pressure from other countries D) they want more profit for their factories
