Sometimes it is difficult to talk to taxi drivers. They must give all their attention to the road as they work out the shortest way to the place where you are going. However, passengers from Wangfujing were in surprise when they took a taxi. The driver just would not stop talking in English.

    Organized by the Cultural and Education Section of the British Embassy, “Dare to Speak” examines if Chinese people will speak English in “real-life” situations.

    Matthew Knowles, an acting student from South Carolina at Beijing Film Academy, acted the part as the “driver”. He collected six passengers on Saturday morning, most of whom were female white-collar （白领）workers.

    “Of course they were surprised at first, wondering why I'm driving a taxi, and wondering whether this is a real taxi, but then most of them were pretty willing to speak,” he said. Knowles said he was also surprised by his “passengers”. “Apart from my first ‘passenger', who could speak very little English, all the rest spoke English very well, and it was fun to communicate with them,” he said, adding that some “passengers” were quite talkative.

    The “foreign taxi driver” project was just one of the “Dare to Speak” activities, which have been going on since the end of October. Other projects included a foreign store owner near a high school in Beijing, a cook in a Shanghai university canteen. They were testing the willingness of Chinese people, especially students and white-collar workers, to speak to foreigners in English.

    Rong Xin, senior manager of IELTS （雅思） with the British Embassy, said they hoped to let IELTS takers in China know that communication is the ultimate goal of IELTS.

    “We hope that more and more IELTS takers in China can realize the importance of communicating in English in real life, instead of just getting high test scores,” she said.

One moment it was quiet and calm in the forest, the next, the air was charged with tension. The elephant had heard the distant alarm calls of animals and her mood suddenly changed. I urged the elephant deeper into the forest. We sounded like a forest fire — cracking, snapping, trailblazing. But through all the noise came a sharp warning cry. The elephant stopped and we heard it again — the tell-tale call of a spotted deer.

    I looked quickly around the shadows of the forest. Rays of sunlight shone through tree branches, beneath which the patchwork（交错）of green plants and shadows-within-shadows would make tiger stripes（条纹）look more attractive. Apart from an occasional noise from the elephant's stomach, the forest was silent.

    Gradually, the tension slipped from our bodies. The elephant seized a nearby branch and put it into its mouth. I reached forward and gently moved my hand over the elephant's neck; there was a soft part, free of wrinkles and hairs, behind her ear.

    This was my fourth time to sense the aura of the forest in Corbett, although I saw no tigers in the end. Located at the foot of the Himalayan mountains, Corbett is home to about 135 Bengal tigers, but the forest seemed to be guarding their whereabouts（出没处）, a silent reminder of their secrecy and rarity. Still, I was happy enough touching the elephant behind the ear. If I had so desperately wanted to see a tiger, I could have gone to a zoo. After all, spotting tigers merely confirms their beauty; tracking them can make you aware of something more.

    My husband and I wanted desperately the instant transformation from typical consumers to eco-conscious people. We switched our light bulbs to CFL(compact fluorescent light) bulbs to conserve energy. We went about the house turning off lights and unplugging appliances that weren't in use. But the rate of global warming exceeded our snail's pace conversion to greenhood. So I pressed onward.

    I decided to put veganism(素食主义) at the top of our agenda. Vegans refuse any animal flesh or commercial goods made from any animal byproducts such as milk or fats. All the family applauded this option except for my husband. Some kind of animal needed to sacrifice its dear life for his meal or it was his dinner. I cooked up a storm, struggling to prepare nutritious meals dominated by not-so-obvious vegan dishes like bean burritos and high-fiber vegetable stir-fry. It took a few days before he realized that he hadn't been eating any meat.

    "I feel like eating beef." he announced. So that night, I took full advantage of a zucchini (一种南瓜), cut it into chunky(粗大的) pieces and cooked them. Then I covered them with spices. My beef-starved husband had some and a curious look crossed his face.

    "Where's the beef?"

    "Living peacefully somewhere on an open plain where it belongs."

    "I knew it" he murmured. "You've surely made great contributions to the boom in cattle." His taste buds were developed completely around the flavor of every kind of animal: cattle, pigs, deer, lamb, chickens and ducks. Converting him was like feeding grass to a lion.

    I'm all for preserving our planet, but what good would it do to save the earth for tomorrow's generation if today's died of starvation? The next day, we went out for burgers. I was very careful to place the paper bag into our recycling bin.

    Chinese scientists recently have produced two monkeys with the same gene, Zhong Zhong and Hua Hua, using the same technique that gave us Dolly the sheep. These monkeys are not actually the first primates(灵长类)to be cloned. Another one named Tetra was produced in the late 1990s by embryo(胚胎)splitting, the division of an early-stage embryo into two or four separate cells to make clones. By contrast, they were each made by replacing an egg cell nucleus(原子核)with DNA from a differentiated body cell. This Dolly method, known as somatic cell nuclear transfer(SCNT), can create more clones and allows researchers greater control over the edits they make to the DNA.

    Success came from adopting several new techniques. These included a new type of microscopy to better view the cells during handling or using several materials that encourage cell reprogramming, which hadn't been tried before on primates. Still, the research process proved difficult, and many attempts by the team failed. Just two healthy baby monkeys born from more than 60 tested mothers. This leads to many researchers' pouring water on the idea that the team's results bring scientists closer to cloning humans. They thought this work is not a stepping stone to establishing methods for obtaining live born human clones. Instead, this clearly remains a very foolish thing to attempt, it would be far too inefficient, far too unsafe, and it is also pointless.

    But the scientists involved emphasize that this is not their goal. There is now no barrier for cloning primate species, thus cloning humans is closer to reality. However, their research purpose is entirely for producing non-human primate models for human diseases; they absolutely have no intention, and society will not permit this work to be extended to humans. Despite limitations, they treat this breakthrough a novel model system for scientists studying human biology and disease.

Let's face it. No one drinks diet sodas for the taste. People drink diet sodas in the hope that it will help them lose weight or at least keep them from gaining it. Yet it seems to have exactly the opposite effect, according to a new study.

Researchers from the University of Texas said those who drank two or more diet sodas a day had waist size increases that were six times greater than those who didn't drink diet sodas. "What we saw was that the more diet sodas a person drank, the more weight they were likely to gain," said Sharon Fowler.

The study was based on data from 474 participants in a large, ongoing research project, where the participants were followed for nearly 10 years.

While the findings are surprising, they also offer some explanations.

Nutrition expert, Melanie Rogers, who works with overweight patients in New York, has found that when patients are switched from regular to diet sodas, they don't lose weight at all. "We weren't seeing weight loss necessarily, and that was confusing to us," said Rogers.

So why would diet soda cause weight gain？No one knows for sure yet, but it could be that people think they can eat more if they drink diet sodas, and so over﹣compensate (补偿) for the missing calories.

A related study found some sweeteners (甜味剂) raised blood sugar levels in some mice. "Data from this and other potential studies suggest that the promotion of diet sodas and artificial sweeteners may be risky," said Helen P. Hazuda, professor at the University of Texas's school of medicine." They may be free of calories, but not of consequences. "
