精彩導讀

人類對環境的污染，正以不知不覺的方式進行。人類可能將面臨一個沒有鳥、蜜蜂和蝴蝶的寂靜世界。本文節選自《寂靜的春天》，以寓言開頭向我們描繪了一個美麗村莊的突變，并從植物到地區到人類自身，全方位地揭示了化學農藥的危害。作者借此向世人發出警告，要人們立即認識到可能會面臨的巨大災難，并采取行動保護環境。Pre-reading

Spring is a time when everything thrives.It is a lively and hopeful season.What does the author mean by describing it to be silent？

There was once a town in the heart of America where all life seemed to live in harmony with its surroundings.The town lay in the midst of prosperous farms， where， in spring， white clouds of flowers above the green fields.In autumn，oak and maple and birch（樺樹）set up a blaze （火焰）of color that flamed and flickered（閃爍）across a background of pines.Then foxes barked in the hills and deer silently crossed the fields.

Along the roads，wildflowers delighted the traveler's eye through much of the year.Even in winter the roadsides were places of beauty，where countless birds came to feed on the berries and on the seed heads of the dried weeds rising above the snow.The countryside was， in fact， famous for the abundance and variety of its bird life，and when the flood of migrants was pouring through in spring and fall people traveled from great distances to observe them.Others came to fish the streams，which flowed clear and cold out of the hills and contained shady（成蔭的）pools where trout （鮭魚）lay.So it had been from the days many years ago when the first settlers raised their houses， sank their wells， and built their barns（谷倉）.

Then some evil spells（符咒）settled on the community:mysteriousdiseasessweptthe flockso chickens;the cattle and sheep sickened and died.In the town the doctors were more and more puzzled b new kinds of sickness appearing among their patients.There had been several sudden and unexplained deaths，not only among adults but even among children.

There was a strange stillness.The birds，for example—where had they gone?The feeding stations in the backyards were deserted.The few birds seen anywhere trembled violently and could not fly.It was a spring without voices;there was now no sound only silence lay over the fields and woods and marsh.

The roadsides， once so attractive， were now lined with browned and withered （枯萎的）plant as though swept by fire.There deserted by all living things， it,too， was silent.Even the streams were now lifeless.Anglers（釣魚者）no longer visited them，for all the fish had died.

Some weeks before,a white powder had fallen like snow upon the roofs and the lawns，the fields and streams.

No witchcraft（魔法），no enemy action had silenced the rebirth of new life in this,in this stricken world.The people had done it themselves.

This town does not actually exist.I know of no community that has experienced all the misfortunes describe.Yet every one of these disasters has actually happened somewhere，and many real communities have already suffered a substantial number o them，and this imagined tragedy may easily become a harsh reality we all shall know.

Ⅲ.難句分析

1.There was once a town in the heart of America where all life seemed to live in harmony with its surroundings.The town lay in the midst of prosperous farms， where， in spring， white clouds of flowers above the green fields.從前，在美國中部有一個城鎮，這里的一切生物看來與其周圍環境生活得很和諧。這個城鎮坐落在繁榮的農場中央。春天，繁花像白色的云朵點綴在綠色的原野上。

本句是There be句型，其中包含where引導的兩個定語從句，分別修飾“a town”和“The town”。 先行詞是表示“地點”或任何含有“抽象地點意義”的名詞時一般用where引導定語從句。

2.In autumn，oak and maple and birch set up a blaze of color that flamed and flickered across a background of pines.Then foxes barked in the hills and deer silently crossed the fields.秋天到了，橡樹、楓樹和樺樹色彩斑斕，在一片松樹林間火焰般地燃燒與跳躍。狐貍在小山上叫著，小鹿靜悄悄地穿過了籠罩著秋天晨霧的原野。

首句是that引導的定語從句，修飾名詞color。flamed and flickered意為“燃燒與跳躍”，采用的是英語押頭韻的修辭手法，類似的還有pride and prejudice（傲慢與偏見），safe and sound （平平安安），now o never（機不可失，失不再來）。押頭韻的修辭手法一般在詩歌、散文、廣告、演講等文體中應用廣泛。此處使用“flamed and flickered”能使語言讀起來更具有音韻美，借此比喻橡樹、楓樹和樺樹色彩斑斕，更加突出了以前小鎮的秋天美感，更具有畫面感了。第2句中的barked和silently為一動和一靜的效果，分別描寫狐貍的叫喚聲和小鹿靜靜穿過原野的動作。
