Unit8 Protecting Our environment;appreciate; 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 a checkerboard of prosperous farms, with fields of grain and hillsides of orchards where, in spring, white clouds of bloom drifted above the green fields. In autumn, oak and maple and birch set up a blaze of color that flamed and flickered across a backdrop（背景） of pines. Then foxes barked in the hills and deer silently crossed the fields, half hidden in the mists of the fall mornings.;Along the roads, laurel, viburnum and alder, great ferns and wildflowers delighted the travelers 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 pools where trout 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.;在路的两旁，一年中许多时候，月桂树、荚莲、桤木、蕨类植物和各样的野花都能让过往的行人赏心悦目。 即使是冬天，路边的景色依旧是美不胜收，那里无数的小鸟来觅取浆果莓和露在雪地上的枯枝上的种子。 事实上，这乡村正是由于鸟类的数量和种类之繁多而出名的。在候鸟群潮涌而来的春秋季节，人们从大老远的地方慕名前来欣赏。 还有的人来这里的小溪垂钓。清冽的溪水从山中流出，溪水中有许多鳟鱼藏身的背阴的水潭。 所以，从许多年前开始，第一批居住者就在这里盖房挖井，搭起了自己的谷仓。;Language Points:;1.2.
