　　阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项，并在答题卡上将该项涂黑。
A
　　Soon it may be harder to stop and smell the roses.
　　Growing levels of air pollution from power plants and automobiles have reduced flower fragrances (芬芳) by up to 90 percent in the US.That is compared with pre-industrial levels,a new study has found.
　　The trend is unpleasant for human noses,but may be life - threatening for bees and butterflies.
　　"Many insects find flowers by folowing the scent(香味) produced by those flowers," said the studies lead author Jose D.Fuentes,an environmental scientist at the University of Virginia.
　　"The increasing pollution makes it difficult for them to locate the flowers and feed on their nectar(花蜜)."
　　Scientists have alrady known that flowers produce scent molecules(分子) that bond with pollutants.The process breaks down the plants' sweet smell.
　　With more pollution in the air,the scent molecules don't remain effective as long and travel shorter distances on the wind.
　　The new study suggests that in the mid - 19th century,when pollution levels were first recorded,scent molecules would have been able to travel some 1,000 to 1,200 meters.
　　Today,in the polluted air found downwind of large cities,scentst may only make it some 200 to 300 meters.
　　The report was recently published in the journal,Atmospheric Environment.
　　Bee farmers have reported that bee populations are dropping dramatically in many parts of the world in recent years. Could these missing scents be a factor?
　　Scientists trying to hind the cause of bee population declines have blamed bacteria,pesticides,and even cellphone radiation.
　　Jay Evans,an entomologist(昆虫学者) at the US Department of Agriculture's bee research laboratory,was interested in the new study.But he says he hasn't seen bee behavior that suggests trouble with scents.
　　"Over the last couple of summers I don't think the bees in this area were bringing in much less food,"he said.
　　"It might be that they had to work harder,but it seems like as long as there were bees to collect food they were finding flowers somewhere."
　　But Fuentes fears that the fading smell of flowers may stress insects that are already faced with other threats.
　　"The effects shown in these studies will simply exacerbate whatever the bees are going through right now,"he said.
　　"It's something that is really worthwhile paying attention to."

What’ s the fastest way to learn a language?

Learning a new language seems hard and frightening as
we look back on the years of grammar and translations in
school．Yet babies communicate t eighteen months and speak
the language fluently before they go to school.
Firstly and most importantly, a child’ s natural language-learning ability exits only in a speech environment free of translations and explanations of translations and explanations of grammar．Secondly, a child’ s language learning speeds up by constant feedback（反馈）from family and friends．Thirdly, children learn through play.
At Rosetta Stone, you know adults can recover the native language-learning ability they once had as children．At every step and in every skill, you receive immediate and actionable feedback, including speech recognition（识别）, advice and attention.
Every act is an act of play for children and there’ s no reason why it should be different for learners of any age．With Rosetta Stone programs, you rediscover the joy of learning languages．Clever, puzzle-like activities produce sudden “aha!” moments and astonishing language discoveries, we see it all the time．A slow of recognition, as though the brain suddenly realizes what is like to learn a language as a child.
