monitoring air quality and planning biking routes and walking paths,suggests a new study by scientists at western washington university in bellingham.leaves along bus routes are up to 10 times more magnetic than leaves on quieter streets.that magnetism comes from tiny particles(微粒) of pollution that float through the air and either stick to leaves or grow right into them.geophysicist bernie housen and his colleague luigi jovane collected several leaves from 15 trees in and around bellingham.five of the trees lay next to busy bus routes.five sat on parallel but much quieter side streets.five were in a rural area nearby.using two measurement techniques,housen and jovane found that leaves along bus routes were between 2 and 8 times more magnetic than leaves from nearby streets and between 4 and 10 times more magnetic than rural leaves.breathing in particles of pollution has been linked to a number of negative health consequences,including breathing troubles and even heart problems.tiny particles get deep into the lung tissues.the new study suggests that biking or walking along heavy bus routes might be bad for your health.thats something cities might want to consider as they plan new routes for cyclists and pedestrians.while many details remain to be worked out,the study also suggests that collecting tree leaves can be a simple and effective way to measure the load of particles in the air.european researchers have been exploring the idea for a while.“using trees is a nice,low-tech way to do these studies and you dont need to use expensive particle collectors,”housen said.“if it works,you could easily collect a lot of data from a region.you could even have kids collect leaves.”1.bernie housens new study suggests that .a.trees should not be planted along roadsb.heavy traffic may lead to more magnetic leavesc.magnetic leaves can give off poisonous gasd.tiny particles are not likely to cause breathing troubles答案:b提示:细节理解题。bernie housen和luigi jovane所研究的只是树叶磁性的高低意味着吸收尘埃的多少,可以作为衡量路上交通拥挤的程度和对人身体健康的影响度的一种方法。故答案为b项。2.which of the following is true according to the text?a.choosing walking paths is of great significance.b.leaves in rural areas are not magnetic.c.biking along heavy bus routes is great exercise.d.its impossible for tiny particles to grow into plants.答案:a提示:推理判断题。由文章第六段可以推断出答案。3.the last paragraph implies that using tree leaves to measure the load of particles in the air is .a.expensiveb.easyc.ridiculousd.complex答案:b提示:细节理解题。文章倒数第二段就已经提到“.collecting tree leaves can be a simple and effective way to measure.”最后一段又提到这种方法不需要很复杂的科学仪器,采树叶就是小孩子也可以做,意味着此种方法的简便性。故答案为b项。4.what would be the best title for the passage?a.collecting tree leaves is simpleb.its easy to choose biking routesc.air quality may affect peoples healthd.tree leaves may be powerful air quality indicators答案:d提示:主旨大意题。文章一开始就指出了树叶可以作为跟踪检测空气质量的工具,有助于我们选择骑车路线和步行途径。.语法填空wife:shall i phone 1 tell your secretary youre not going to

songs,blues,and so on?in high school i took one course calling music appreciation which i great enjoyed.this was not only to learn how to play a specific instrument but learn how to read and listen to music as an art form.we read the stories about the life of many composers and the history of the music instruments themselves.sometimes we listen to tapes in the language laboratory or concerts.music is sometimes called an universal language.a composer whom cannot speak a single word of our language can make us feel joy and pride,excitement and despair,peace and mystery along his music.答案:what is your favourite kind o
