Ques:Dogs have long been used to find explosives and drugs.Now,a new study shows that man's best friend can also help to find lung and breast cancer,researchers report in integrative Cancer Therapies.The findings show that trained ordinary household dogs can detect early--stage lung and breast cancers by smelling the breath samples of patients. Researchers have found that cancer cells send out molecules different from those of healthy ones,and that might be sensed by smell by the highly sensitive dog's nose. For the study,five dogs were trained by a professional instructor to respond differently to breath samples of healthy and cancer patients."The dogs learned to sit or lie down in front of cancer patient samples and to ignore control samples through the method of food reward," McCulloch explained. After a period of training,researchers tested the animals'ability to distinguish cancer patients from controls.The animals were given breath samples from 55 patients with lung cancer,3 1 with breast cancer and 83 healthy controls who were not included in the original training period. McCulloch's group found that the dogs were able to correctly distinguish the breath samples of cancer patients from those of the control subjects in about 90 percent of the cases.The dogs were also able to detecting early-stage lung and breast cancers. "These results show that there is hope for early detection,"McCulloch said.The re-searches are planning to conduct further studies on the breath composition of cancer patients to possibly design an electronic device that can do the dogs'job."A dog's nose is so powerful it can detect odors 10 000 to 100 000 times better than a human nose can.I hope people will be interested in doing this research,"McCulloch added,"It shows that there is definitely something out there." Which of the following would be the best title? A) Special Noses of Dogs B) Dogs and Cancer C) Dogs Smell Signs of Cancer D) McCulloch'S New Discovery

Ques:It is six o'clock in the morning. You are asleep in my left arm and I am learning the art of one-handed typing. Your mother, more tired yet more happy than I've ever known her, is sound asleep in the room next door. When you're older we'll tell you that you were born in Hong Kong in the lunar year of the pig. "It's a boy, so lucky," our neighbours told us. They said you were the first baby to be born in the block this year. This, they told us, was good Feng Shui, in other words, a positive sign. Naturally your mother and I were only too happy to believe that. Your coming has turned me upside down and inside out. I am pained by the memory of each suffering child I have come across on my journeys as a journalist. To tell you the truth, it's nearly too much for me to even think of the children being hurt and abused and killed. Last October, in Afghanistan, when you were growing inside your mother, I met Sharja, aged twelve, motherless, fatherless, guiding me through the grey ruins of her home. Everything was gone, she told me. There is another memory of Rwanda, and the churchyard where I found a mother and her three young children huddled  together where they'd been beaten to death. The children had died holding on to their mother. Daniel, these memories explain some of the protectiveness I feel for you, and the occasional moments of blind terror when I imagine anything bad happening to you. The author mentions some of his painful memories because   _  . A) he wants his son to care for others B) he feels more pain thinking about them as a father C) he hopes to forget the tragedies he witnessed D) his experience has affected his mental health

Ques:(The Guardian):              More UK universities should be profiting from ideas A repeated criticism of the UK's university sector is its noticeable weakness in translating new knowledge into new products and services. Recently, the UK National Stem Cell Network warned the UK could lose its place among the world leaders in stem cell research unless adequate funding and legislation could be assured, despite an annual PS40m spent by the Department of Health on all kinds of research. However, we do have to challenge the unthinking complaint that the sector does not do enough in taking ideas to market. The most recent comparative data on the performance of universities and research institutions in Australia, Canada, USA and UK shows that, from a relatively weak starting position, the UK now leads on many indicators of commercialization activity. When viewed at the national level, the _ (interference) of the past decade have helped transformed the performances of UK universities. Evidence suggests the UK's position is much stronger than in the recent past and is still showing improvement. But national data masks the very large variation in the performance of individual universities. The evidence shows that a large number of universities have fallen off the back of the pack, a few perform strongly and the rest chase the leaders. This type of uneven distribution is not strange to the UK and is mirrored across other economies. In the UK, research is concentrated: less than 25% of universities are receiving 75% of the research funding. These same universities are also the institutions producing the greatest share of PhD graduates, science citations, patents and license income. The effect of policies generating long-term resource concentration has also created a distinctive set of universities which are research-led and commercially active. It seems clear that the concentration of research and commercialization work creates differences between universities. The core objective for universities which are research-led... What does the author say about the national data on UK universities' performance in commercialization? A) It masks the fatal weaknesses of government policy. B) It indicates their ineffective use of government resources. C) It does not rank UK universities in a scientific way. D) It does not reflect the differences among universities.

Ques:Many people rely on a cup of coffee or two to wake them up in the morning or refresh them during the working day, but now a chemist has come up with a speedy alternative to drinking coffee. U.S. biochemist Ben Yu has created 'Sprayable Energy', which claims to be the world's first caffeine - based topical energy spray. He said tired workers can spray a 'shot' of caffeine onto their skin without experiencing a strong noise, taking in unnecessary calories or being stuck with a nasty aftertaste like they might get from drinking energy drinks or coffee. The tasteless caffeine spray is absorbed through the skin and spread through the body over a number of hours to deliver a caffeine hit that lasts longer than drinking a cup of coffee. The only active ingredient in the spray is caffeine, which is very similar to nicotine in structure. Each spray 'Sprayable Energy' contains around a quarter of the amount of caffeine found in a cup of coffee, but apparently has the same effect as a full cup. The website said: "The reason for this is our product isn't entirely metabolized  by the liver before entering your system and becoming available to your body." Sprayable Energy's website recommends that users apply the spray in places where they normally spritz perfume, such as wrists, the neck or behind the ears, but warns users not to exceed 20 times a day. It claims that after spraying the product on the skin, users will feel awake and focus without being over-excited, which is common with coffee and energy drinks. Which of the body may not be suitable to apply "Sprayable Energy"? A) The neck. B) Behind the ears. C) Wrists. D) Mouth.
