1、New Product Will Save Lives
Drinking water that looks clean may still contain bugs, which can cause illness. A small company called Genera Technologies has produced a testing method in three stages, which shows whether water is safe. The new test shows if water needs chemicals added to it, to destroy anything harmful. It was invented by scientist Dr. Adrian Patton, who started Genera five years ago. He and his employees have developed the test together with a British water company.
Andy Headland, Genera＇s marketing director, recently presented the test at a conference in the USA and forecast good American sales for it. Genera has already sold 11 0fits tests at $42,500 a time in the UK and has a further four on order. It expects to sell another 25 tests before the end of March. The company says it is the only test in the UK to be approved by the government.
Genera was formed five years ago and until October last year had only five employees; it now employs 14. Mr. Headland believes that the company should make around $19 million by the end of the year in the UK alone.
Genera has increased the number of its employees recently.

2、Fermi Problem
On a Monday morning in July, the world＇s first atom bomb exploded in the New Mexico desert, Forty seconds later, the shook waves reached the base camp where the Italian-American physicist Enrico Fezmi and his team stood. After a mental calculation, Fermi announced to his team that the bomb＇s energy had equated 10,000 tons of TNT. The bomb team was impressed, but not surprised. Fermi＇s genius was known throughout the scientific world. In 1938 he had won a Nobel Prize. Four years later he produced the first nuclear chain reaction, leading us into the nuclear age. Since Fermi＇s death in 1954, no physicist has been at once a master experimentalist and a leading theoretician.
Like all virtuosos (大师), Fermi had a distinctive style. He preferred the most direct route to an answer. He was very good at dividing difficult problems into small, manageable bits talent we all can use in our daily lives.
To develop this talent in his students, Fermi would suggest a type of question now known as a Fermi problem. Upon first hearing one of these, you haven＇t the remotest notion of the answer, and you feel certain that too little information had been given to solve it, Yet when the problem is broken into sub-problems, each answerable without the help of expert. s or books, you can come close to the exact solution.
Suppose you want to determine Earth＇s circumference without looking it up. Everyone knows that New York and Los Angeles are about 3,000 miles apart and that the time difference between them is three hours. Three hours is one-eighth of a day, and a day is the time it takes the planet to complete one rotation, so its circumference must be eight times 3000 0r 24000 miles. This answer differs from the true value, 24,902. 45 miles, by less than four percent.
Ultimately the value of dealing with everyday problems the way Fermi did lies in the rewards of making independent discoveries and inventions. It doesn＇t matter whether the discovery is as important as determining the power of an atom or as small as measuring the distance between New York and Los Angeles. Looking up the answer, or letting someone else find it deprives you of the pleasure and pride that accompany creativity, and deprives you of an experience that builds up self-confide. Thus, approaching personal dilemmas as Fermi problems can become a habit that enriches your life.
Fermi＇s team was impressed by Fermi＇s announcement in the base camp because he could even work out the power of the atom bomb in his mind.

3、African wild dog
Finding a babysitter while you go out to work is, for example, an inconvenience. For the African wild dog, one of the continent＇s most endangered carnivores （食肉动物), it＇s a matter of life and death. A new research shows that once packs (兽群) fall below a certain size, they are not enough animals to both hunt food and stay at home protecting the young.
The African wild dog has declined drastically over the past century. Habitual loss (栖息地的丧失), persecution and unexplained outbreaks of disease have all been blamed. Only 3, 000 to5,000 animals remain, and the species is expected to go extinct within decades if the trend continues.
Other large carnivores such as the spotted hyena (鬣狗) face similar pressures, yet are not declining. Now Franck Courchamp of Cambridge University has found a reason why. The dog＇s weakness lies in its social organization.
Within each pack of up to 20 adults and pups, only the dominant male and female breed. The remaining animals help raise the pups, cooperating to hunt prey and defend the kill from other carnivores.
Because pups can＇t keep up on a hunt, large packs leave an adult behind to protect them from predators (捕猎者), which include lions and hyenas. But leaving a babysitter also carries costs. A smaller hunting party is less able to tackle large prey and to defend the kill. There is also one less stomach in which to carry food back to the den, and one more mouth to feed when they get there.
Courchamp investigated this awkward trade-off (权衡) by modeling how the costs of a babysitter change with decreasing pack size. This showed that packs of more than five adults should be able to feed all the pups and still spare a babysitter. But with smaller packs, either the hunting or the babysitting suffers, or the animals have to compensate by increasing the number of hunting excursions which itself carries a cost to the pack.
Field observations in Zimbabwe supported the model. Packs of five animals or fewer left pups unguarded more frequently than larger packs did. There was also evidence that when they did leave a babysitter, they were forced to hunt more often.
A pack which drops below a critical size becomes caught in a vicious circle (恶性循环), says Courchamp, who is now at Paris-Sud University. "Poor reproduction and low survival further reduces pack size, culminating in (最终造成) failure of the whole pack. " And deaths caused by human activity, says Courchamp, may be what reduce pack numbers to below the sustamable threshold. Mammal ecologist Chris Carbone at London＇s Institute of Zoology agrees. Maintaining the integrity of wild dog packs will be vitalin preserving the species, he says.
The size of a pack must be big enough for it to survive.【单选题】

4、Travel Across Africa
For six hours we shot through the barren (荒芜的) landscape of the Karoo desert in South Africa. Just rocks and sand and baking sun. Knowing our journey was ending, Daniel and I just wanted to remember all we had seen and done. He used a camera. I used words. I had already finished three notebooks and was into the fourth, a beautiful leather notebook I＇d bought in a market in Mozambique.
Southern Africa was full of stories and visions. We were almost drunk on sensations. The roaring (咆哮) of the water at Victoria Falls, the impossible silence of the Okavango Delta in Botswana.
And then the other things, dogs in the streets, whole families in Soweto livng in one room, a kilometre from clean water.
As we drove towards the setting sun, a quietness fell over us. The road was empty and we hadn＇t seen another car for hours. And as I drove, something caught my eye. Something moved close enough to touch them, to smell their hot breath. I didn＇t know how long they had been there next to us.
I shouted to Dan: "Look!" But he was in a deep sleep, his camera lying useless by his feet. They raced the car for a few seconds, then disappeared far behind us, a memory of heroic forms in the red landscape. When Daniel woke up an hour later I told him what had happened.
"Wild horses?" he said. "Why didn＇t you wake me up, Sophia?"
"I tried, but they were gone after a few seconds."
"Are you sure you didn＇t dream it?"
"You were the one who was sleeping!"
"Typical," he said, "The best photos are the ones we never take."
We checked into a dusty hotel and slept the sleep of the dead.
Sophia wrote about her experiences in notebooks.
