    Expensive perfumes (香水) come in tiny bottles, but many hide a whale-sized secret.

    To perfect a particular smell, perfume-makers often use an ingredient that comes from sperm whales, called ambergris (龙涎香). But using ambergris, which helps a perfume last longer, is strongly opposed by many people who think it is wrong to kill whales just so we can smell sweet. Joerg Bohlmann is neither a perfumer nor a whale expert. He's a plant biologist at the University of British Columbia in Canada. But his discovery of a new plant gene (基因) might push whales out of the perfume business.

    The gene comes from fir trees, found throughout North America and commonly used as Christmas trees. The trees produce a chemical that can be used in perfume in place of ambergris-but with a catch. "There's a problem that many people wouldn't consider. In the tree, the chemical is mixed with many others. That makes separation a challenge," Bohlmann says. "lt's like trying to isolate sugar from a biscuit. "

     This is where science becomes useful. When Bohlmann learned that fir trees produce the ambergris-like chemical, he decided to use his gene know-how to find the instructions for how to make the ambergris-substitute.

    Bohlmann found that gene and took it out of the tree cells. Then he did something that might sound strange to someone who doesn't work in genetics: Bohlmann put the gene from the tree into yeast (酵母) cells.

    Yeast may sound familiar because it's used to make things like bread, wine and beer. Biologists like to work with yeast because it easily adopts new genes and changes its features and behaviour. When Bohlmann put the fir tree gene into the yeast, the yeast started making the same chemical that had been produced by the tree.

    Perfumers pay big money for ambergris because it is a fixative, which means it holds a smell in place on a person's body.

    "Cheap perfumes smell good in the first hour or so and then everything is gone," explains Bohlmann. "But expensive perfumes are much more stable.  Their smell lasts much longer, for hours or even a day after you apply them. "

    The new chemical, made from the tree genes, can be used as a fixative, too. And using yeast to make it is far cheaper than acquiring ambergris.

    Bohlmann admits he never thought he'd get into the perfume business. But now, he says, producers have been calling to find out how to use his technology in new perfumes.

(1)、It can be inferred from the passage that if a perfume contains ambergris,           .

A、its user probably supports whale hunting B、it is probably very expensive C、its smell will last for about an hour D、there will be a whale symbol on the bottle
(2)、The underlined expression "with a catch" in Paragraph 3 means____.

A、being difficult to hold B、being too similar C、having a hidden problem D、needing further testing
(3)、According to the passage, why are yeast cells often used in genetic research?

A、They're much cheaper to use than ambergris. B、They can reproduce much faster than other cells. C、They share some of the qualities of plant genes. D、They can take on the characteristics of other genes.
(4)、What can we learn about Joerg Bohlmann from the passage?

A、He is opposed to whale hunting. B、He made his discovery during Christmas. C、He has worked in the perfume industry for many years. D、He has previously done genetic research.

    England's highest main-line railway station is in serious trouble, deserted and unmanned since it was officially closed in 1970, Dent, located high in the hills of Yorkshire, wakes up on six summer weekends each year, when a special train unloads walkers, sightseers and people who simply want to catch a train from the highest station to its platforms.

    But even this limited being may soon be brought to an end. Dent station located on the Settel to Carlisle railway line, is said to be surrounded by the most beautiful scenery in the country. But no amount of scenic beauty can save the line because of the British Rail's money problems.

    It is now an open secret that British Rail sees no future for this railway line. Most of its trains disappeared some time ago. Bridges, built a century ago, are falling down. It is not alone. Half a dozen railway routes in the North of England are facing a similar threat. The problem is an old system and an almost total lack of cash to repair it. Bridges and tunnels are showing their ages, the wooden supports for the tracks are rotting(腐烂) and engines and coaches(车厢) are getting old.

    On main lines between large cities, the problem is not too bad. There lines still make a profit and cash can be found to keep them in good condition. But on the country branch line, the situation is different. As track wears out, it is not replaced. Instead speed limits are introduced, making the journey longer than necessary and discouraging travelers.

    If a bridge is dangerous, there is often only one thing for British Rail to do: go out and find money from another places. This is exactly what it did a few months ago when a bridge at Bridling station was threatening to fall down. Repairs were calculated at 200,000 pounds just for one bridge, so British Rail was pleased, and rather surprised when two local councils(理事会) offered half that amount of money.

    The softshell turtle species is officially listed as endangered by the IUCN Red List. Scientists long thought softshell turtles were extinct in the Cambodian part of the Mekong River until they discovered some stragglers (掉队者) in the early 2000s.

    The species had quite a wide historical range across Asia, but much of that range is now completely gone. Much of the turtle's habitat in Southeast Asia have disappeared due to urban and industrial development along the Mekong River. The sand where turtles multiply is routinely carried away for use in construction projects, while fishing nets lift up hatchlings. People also take turtles and their eggs to sell for food.

    Initial surveys in 2003 and in 2007 found two small populations of the softshell turtles along a 30-mile stretch (水域) of the Mekong River. Since then, conservation groups have worked with local communities and officials to increase the wild population of these endangered turtles, including a program to hire former egg collectors to help search for and protect nests instead of harvesting the eggs.

    For the last decade, WCS, Conservation International, the Turtle Survival Alliance and local groups have worked to protect turtle nests. Their goal is to ensure eggs will multiply and hatch, and that baby turtles grow strong enough to eventually take care of themselves in the wild.

    A team recently released 150 hatchlings back into their natural habitat, bringing the total to more than 7,700 baby turtles in the past 10 years.

    Why do some people live to be older than others? You know the standard explanations: keeping a moderate diet, engaging in regular exercise, etc. But what effect does your personality have on your longevity(长寿)? Do some kinds of personalities lead to longer lives? A new study in the Journal of the American Geriatrics Society looked at this question by examining the personality characteristics of 246 children of people who had lived to be at least 100.

    The study shows that those living the longest are more outgoing, more active and less neurotic (神经质的) than other people. Long-living women are also more likely to be sympathetic and cooperative than women with a normal life span. These findings are in agreement with what you would expect from the evolutionary theory: those who like to make friends and help others can gather enough resources to make it through tough times.

    Interestingly, however, other characteristics that you might consider advantageous had no impact on whether study participants were likely to live longer. Those who were more self-disciplined, for instance, were no more likely to live to be very old. Also, being open to new ideas had no relationship to long life, which might explain all those bad-tempered old people who are fixed in their ways.

    Whether you can successfully change your personality as an adult is the subject of a longstanding psychological debate. But the new paper suggests that if you want long life, you should strive to be as outgoing as possible.

    Unfortunately, another recent study shows that your mother's personality may also help determine your longevity. That study looked at nearly 28,000 Norwegian mothers and found that those moms who were more anxious, depressed and angry were more likely to feed their kids unhealthy diets. Patterns of childhood eating can be hard to break when we're adults, which may mean that kids of depressed moms end up dying younger.

    Personality isn't destiny, and everyone knows that individuals can learn to change. But both studies show that long life isn't just a matter of your physical health but of your mental health.

    Charlie is a teacher and his wife, Maria is an artist. The night before last, just before the longest day of the year, Charlie was sitting in a deckchair enjoying the warm summer air when Maria touched his shoulder and he could tell immediately she was a little worried about something. He asked her what the matter was and she replied that there was a strange thing on the jacket that was hanging in the bedroom. They had both lived in the West Indies (西印度群岛) and had seen a lot of strange creatures in their house before. But now they were living in England and so Charlie just laughed and said he would have a look at the "thing".

    He walked to the bedroom. He saw a jacket hanging in the bedroom and went up to it to have a closer look at the "thing". The moment he touched it, the thing sprang into life. Now Charlie experiences fear like the rest of us but when this creature opened its wings, he jumped out of his skin and ran screaming from the room like a small child doing about 100 miles an hour.

    For a moment the next-door neighbours thought that Charlie was murdering his wife because of the noise they could hear. In fact, it was a bat that frightened Charlie.

    Eventually Charlie managed to trap the bat in a box and took it to the garden to let the bat fly. Maria, who had been playing the guitar while Charlie was upstairs, asked Charlie if he had found out what the thing was. "Oh, nothing to worry about", he said casually hoping that the terror could not be seen in his eyes, "it was just a bat."
