Nw read the passage and check yur predictin.
Silent SpringThere was a strange stillness. The birds，fr example—where had they gne? Many peple spke f them ， puzzled and disturbed. The feeding statins in the backyards were deserted. The few birds seen anywhere were mribund；they trembled vilently and culd nt fly. It was a spring withut vices. On the mrnings that had nce thrbbed with the dawn chrus f rbins，catbirds，dves，jays ，wrens ，and scres f ther bird vices there was nw n sund ；nly silence lay ver the fields and wds and marsh.Rachel Carsn was a scientist by prfessin，but these lines frm the pening chapter f her 1962 bk Silent Spring，“A Fable fr Tmrrw”，shw her talent as a writer. By imagining a wrld withut birds，she aimed t alert nt nly the scientific cmmunity but als the general public t the damaging effects f human activity n natural ecsystems—in particular ，t the harmful use f pesticides ，such as DDT. She believed that the chemical industry was knwingly causing harm t plants，animals and even humans，and wished t see pesticides used in a mre respnsible，limited and carefully mnitred way.
Carsn urged peple t make themselves aware f the facts and d smething abut the situatin. Silent Spring cntains a lt f scientific research and case studies. The bk details the gypsy mth eradicatin prgramme，which killed birds，in additin t gypsy mths. Anther case study was the fire-ant prgramme that killed cws，but nt fire ants. The bk als gives dzens f ther examplesf eradicatin prgrammes that did nthing t reduce the prblems they were riginally designed t slve. The 50 r s pages at the end f the bk list Carsn’s surces，shwing hw thrugh and precise she was as a scientist.Carsn’s message was very alarming，causing a great increase in envirnmental awareness. Its impact was immediate and far-reaching：the use f DDT was banned and the Envirnmental Prtectin Agency （EPA）was established in the US. Silent Spring was therefre regarded as a milestne in the launch f the green mvement in the Western wrld. It als earned Carsn a psthumus Presidential Medal f Freedm and put her face n the 17-cent US stamp.
Silent Spring was nt，hwever，received psitively by everyne. Thugh Carsn’s research was strng and was supprted by mst scientists wh reviewed her wrk，the bk quickly became a target fr critics in the pesticide industry. They said that Carsn did nt understand the science behind her arguments because she was a marine bilgist rather than a chemist. Sme als said that her wrk was mre emtinal than scientific. These were attempts t damage Carsn’s reputatin and stp her wrk frm influencing public plicy，but she remained determined t stand by her research. Carsn appeared in public and n televisin t defend her claims—and tday，mre than 50 years after it was published ，the vice f Silent Spring is still ringing lud and clear.Persnally，I enjy Carsn’s bk. She made a crucial but ptentially difficult-t-understand subjectinteresting and accessible t millins f peple. This is nt s much because f the quality f her arguments，strng thugh they are，but because f the beauty and elegance f her writing. Her bk nt nly changed the wrld；half a century later it remains a bk that deserves t be reread tday，s that we can nce again feel urselves warm t the fire f its passinate message. Fr unless we d listen t Rachel Carsn’s warning，ne day we may wake up t the strange and quiet hrrr f anther silent spring.
