第三部分阅读理解(共两节,满分40分)
第一节(共15小题;每小题2分,满分30分)
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."
56.What's the passage mainly about?
A.How greatly air plooution affects our lives.
B.Effects of air pollution on bee populations.
C.Measures to fight air pollution.
D.The rapid decline of bee populations in the world.
57.According to the passage,Jay Evans probably agrees that ______ .
A.bees are the insect that suffers most from air pollution
B.bees are at risk of dying out owing to air pollution
C.the fading smell of flowers doesn't affect bees so greatly as was thought
D.as is often the case,bees fail to locate the flowers because of the missing scents
58.The word"exacerbate" in the last paragraph but one probably means ______.
A.worsen B.improve C.get rid of D.decrease
59.Which of the following is NOT true according to the passage?
A.The more air pollution there is in a region,the greater the destruction of the flower scents.
B.Bacteria,pesticides,and cellphone radiation are blamed for causing the decline of bees.
C.The scent molecules produced by flowers in a less polluted environment oculd travel longer and farther.
D.Air pollution does more harm to insects such as bees and butterflies than human beings.

The New York Institute for Special Education (NYISE) used to be a school for the blind. It was established in 1831, and it was one of the first places in the USA to offer education to blind children. Today NYISE's students are blind or learning disabled and aged between 3 and 21. they can attend school as day students or they can board on a weekly basis.
Another special institution is Gallaudet University in Washington D. C.. This is the only university in the world that is exclusively for the deaf and hearing-impaired. It was founded in the 1850s, but it was only permitted to award degrees to its graduates after 1863.
Some special schools cater for people with particular skills. Established in 1984 for students with artistic or musical talent, La Gauardia High School of Music and Performing Arts in Mew York was the first public school of this type. The school has an excellent reputation both in the United States and internationally.
When they are 14 or 15 years old, students living in New York can take the Specialized High Schools Examination. If they pass, they are allowed to study at one of the city's special high schools. The Bronx High School of Science is one of these institutions. Bronx Science had only 300 pupils when it was founded in 1938. the school used to exclusively for boys, but today it has over 3,000 male and female students specializing in science.
