Although many butterflies remain to be decreasing in the long run, last year three quarters of endangered species saw an increase in number, including some rare species.
Experts said the improvement in the butterflies’ fortunes was likely to be the result of effective action on protection, such as leaving open wetland in woods where flowers can grow, and better weather in 2010 after three damaging wet summers.
Dr Tom Brereton said butterflies are extremely sensitive to changes in the weather. Last ye
ar saw a warm summer for successful feeding, which helped a number of butterflies in some way.
He even said climate change could be benefiting some butterfly species but many other butterfly species suffer from it. For example, the mountain ringlet suffers as it needs cold climates. And at the same time, the change is too rapid for most to get used to.
In the long run butterfly numbers have continued to drop, with three quarters of the nearly 60 species found in Britain seeing numbers fall in recent decades and nearly half of them seriously threatened.
The Lulworth skipper, one of the UK’s rarest butterflies, had its worst year since 1976, and there are people worrying that changing the environment to benefit other species may be harming this kind of butterfly. Wild flowers have been grown in some places to help other butterflies but the Lulworth skipper needs long grass and wild areas. Meadow browns, the country’s most common species, also had the worst year on record. Some other kinds of butterflies also had a bad year.
However, in the short term many butterflies saw an increase in number in 2010 compared to 2009 levels.

ight,out of mind": throw it away and it`s gone.But imagine what really happens to all the rubbish the world throws away.Now suddenly，the government is worried about mountains of garbage piling up with no place to put them all．
China`s increasing prosperity and urbanlsm create tons of garbage since the 1980s，causing tons of trouble.The amount of paper,plastic and other garbage has increased more than three times in two decades to about 300 million tons a year．As busy families are shifting from fresh to packaged foods,more garbage is expected．

Food waste is collected by farmers to feed animals.
Even though we make an effort to recycle our solid waste，the amount of waste keeps increasing each year．Our biggest problem is where to put the solid waste and how to keep it from polluting our environment.If the solid waste is disposed incorrectly,it can pollute earth`s surface an underground water supplies.Currently,Our municipal waste goes to landfills or garbage dumps.
The waste must be treated to keep rats，flies and other anlmas from building their homes in the landfills.The treatrment also prevents the growth of bacteria that carry diseases．

Housing is always an important comcern,and things were no different back in Canada`s early days.The nailve population had several answers to the housing problem．
The igloo if a house built of ice or snow and is still in use today in more primitive areas of Canada`s north．The Inuit people find them the best type of housing,eSpecially when away from home on hunting or fishing trips.The igloos used o such trips are smaller and only temporary homes to be used for a few nights at most．Igloos are domeshaped（圆顶形的）and made of blocks of ice or snow.First a hole is dug out in the snow and this forms the lower part of the igloo.Then the blocks of ice or snow are built in a slope inwards and upwards from this base.Often a short tunnel leads to the door.This prevents the cold winds and snow blowing into the structure.
Tipis（or tepees）are the conical（圆锥形的）tents used by the majority of native People
across America.Some Canadian aboriginal people still prefer them to other types of housing. These structures are formed by a frame of poles covered with，usually，iether buffalo hide（水牛皮）or birch bark（桦树皮）．A hole at the top lets out the smoke from the cooking fires．Native people mostly travel from place to place,following their food supple across the countryside.Tepees are easy to taKe down，carry and put up at the next stopping place．
Another type of house iS the long house.This is exactly what the name suggests-a long narrow building that could house ten to twenty families.Built of poles covered with hides,there houses are common to the Iroquois people of 0ntario and NeW York.These structures are also on the West Coast by the Squeamish Indians.They are usually occupied by an exended family and divided into individual rooms,each with its own cooking fire.They are decorated with totem emblems （图腾标志）and a totem pole by the front door tells the history of the family．

Taste is such a subjective matter that we don’t usually conduct preference tests for food. The most you can say about anyone’s preference is that it’s one person’s opinion. But because the two big cola companies-Coca-Cola and Pepsi Cola-are marketed so aggressively, we’ve wondered how big a role taste preference actually plays in brand loyalty. We set up a taste test that challenged people who identified themselves as either Coca-cola or Pepsi fans: Find your brand in a blind tasting.
We invited staff volunteers who had a strong liking for either Coca-Cola Classic or Pepsi. Diet Coke, or Diet Pepsi. These were people who thought they’d have no trouble telling their brand from the other brand.
We eventually located 19 regular cola drinkers and 27 diet cola drinkers. Then we fed them with four unidentified samples of cola one at a time, regular colas for the one group, diet versions for the other. We asked them to tell us whether each sample was Coke or Pepsi; then we analyzed the records statistically to compare the participants’ choices with what mere guesswork could have accomplished.
Getting all four samples right was a tough test but not too tough, we thought, for people who believed they could recognize their brand. In the end, only 7 out of 19 regular cola drinkers correctly identified their brand of choice in all four trials. The diet-cola drinkers did a little worse-only 7 out of 27 identified all four samples correctly.
Both groups did better than chance would predict, but nearly half the participants in each group made the wrong choice two or more times. Two people got all four samples wrong. Overall, half the participants did about as well on the last round of tasting as on the first, so tiredness, or taste burnout, was not a factor. Our preference test results suggest that only a few Pepsi participants and Coke fans may really be able to tell their favorite brand by taste and price.

A 17-year-old boy，caught sending text messages in class，was recently sent to the vice principal`s office. The vice principal，Steve Gallagher，told the boy he needed to focus on the teach-er，not his cellphone. The boy listened politely and nodded，and that`s when Mr.Gallagher noticed the student`s fingers moving on his lap. He was testing while being scolded for texting. " It was a subconscious act，" says Mr. Gallagher，who took the phone away. " Young people today are con-nected socially from the moment they open their eyes in the morning until they colse their eyes at night.It`s compulsive."
A study this year by psychology students at Covenant College in Lookout Mountain,Ga.,found that the more time young people spend on Facebook，the more likely they are to have lower grades and weaker study habits. Heavy Facebook users show signs of being more sociable，but they are also more likely to be anxious，hostile or depressed.
Almost a quarter of today`s teens check Facebook more than 10 times a day，according to a 2009 survey by Common Sense Media,a nonprofit group that monitors media`s impact on families.Will these young people get rid of this habit once they enter the work force，or will employers come to see texting and `social-network cheeking` as accepted parts of the workday?Think back,When today`s older workers were in their 20s,they might have taken a break on the job to call friends and make after-work plans.In those earlier eras,companies discouraged non-business-related calls,and someone who made personal calls all day risked being fired.It was impossible to imagine the constant back-and-forth texting that defines interactions among young people today.Educators are also being asked by parents，students and educational strategists to reconsider their rules. "In past generations，students got in trouble for passing notes in class. Now students are good at texting with their phones still in their pockets，" says 40-year-old Mr.Gallagher,the vice principal,"and they`re able to communicate with someone one floor down and three rows over. Students are just fundamentally different today.They will take suspensions rather than give up their phones."

A.the employers will not accept young people`s sending text messages
B.a cellphone is a must for today`s older workers instead of young people
C.The employers prefer older workers to young people
