Once upon a time, there was a small town in the center of America, where everything seemed to be in harmony with its surroundings. The town is surrounded by prosperous farms, fields and orchards all over the hillside.从前在美国中心有一个小镇，那里的万物看上去都与其四周的环境融洽相处。小镇的四周是像棋盘交错的兴旺的农庄，还有一块块的田地和一座座遍布山坡的果园。Spring is coming, white flowers are floating on the green fields like clouds; Autumn is coming, the oak, maple and birch trees are colorful, burning and jumping like flames in a pine forest. Foxes bark in the hills, deer jump quietly in the fields, and everything is half hidden in the mist of the autumn morning.春天来了，白色的鲜花云彩般地漂浮在绿色的田野上；秋天到了，橡树、枫树和桦树色彩斑斓，在一片松树林间火焰般地燃烧与跳跃。小山上狐狸吠叫，田野间小鹿静静地跃过，所有的一切都在秋天清晨的薄雾中半隐半现。On both sides of the road, laurel trees, Podocarpus, alder trees, ferns and various wild flowers can make passers-by enjoy themselves at many times of the year. Even in winter, the roadside scenery is still beautiful, where countless birds come to search for berries, berries and seeds on the branches exposed in the snow.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。In fact, this village is famous for its large number and variety of birds. In the spring and autumn season when migratory birds come, people come from far away places to admire. Others come here to fish in the stream. The clear stream flows out from the mountain, in which there are many shady pools where trout hide.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。 Therefore, from many years ago, the first group of residents built houses, dug wells and built their own barns here.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。这部分内容主要考察的是现在完成时的应用：
