    竹村坐落在杭州市郊的青龙山脚下。它三面环山,一面靠水。每当春暖花开时节,山间那婉蜒曲折的溪水便潺潺地流入村前的青龙河中。

    村后,漫山遍野郁郁葱葱,莶翠欲滴。那高大挺拔的是青竹,那纤巧细嫩的乏茶树相互掩映,编织成翡翠的绿衫。    

    春天,茶农家家户户起早贪黑地摘春茶。姑娘们身背茶篓,迎着朝霞,踏着畏露,穿梭般地巡回在茶树家。她们那灵巧的双手不停地上下飞舞:时而如小鸡啄米,时而如彩蝶翩跹,时而又如钢琴家娴熟地演奏贝多芬的《田园交响曲》。一大捧一大捧鲜嫩的茶叶装进了背篓。她们那五彩的衣裳点缀着明丽柔和的绿色的海洋,引得那小蜜蜂看花了眼,忙着追逐那不断晃动的花朵儿。    

    太阳升上了头顶,露珠不知什么时候悄悄地隐没了身子。背篓快满了,只听见此起彼伏的山歌在山坡上(    )。小鸟儿争先恐后,像开赛歌会似的在枝头吱吱喳喳。空气中弥漫着早茶的清香,沁人心脾,使人陶醉。    

    落日的余晖(    )了天空,小鸟归巢了,晚霞也回家了。村里家家的烟囱冒出(    )青烟。婉蜒的山路上晃动着姑娘们的衣衫,小扁担吱嘎嘎地响着,把一担担冒尖的新茶挑下山来,焙制成驰名中外的龙井。    

    每当我品尝这甘醇晶萤的碧茶时,心中便踊起(    )乡思……

    You may have heard of the American Dream, an ideal that has powered the hopes of Americans for generations.

    It began as a belief that the US was a land of opportunity, and that anyone could achieve success through hard work. At times, the dream has referred to home ownership, a good job, retirement security or each generation doing better than the last.

    Yet today, this concept seems to have greatly changed. As Time magazine pointed out, quite different from the older generation, many Millennials (the generation born after 1980) redefine(重新定义) the American Dream as “day-to-day control of your life”. They “prize job mobility, flexible schedules, any work that is more interesting than typing, and the ability to travel”, said the magazine.

    Home ownership, once the cornerstone of the American Dream, is becoming a smaller priority for this generation. Meanwhile, nearly 40% of them choose travel as part of their dream. And entrepreneurship(创业) is a rising favorite, as nearly 26% of Millennials consider self-employment as part of their dream.

    So what has led to this huge change?

    Many point fingers at the poor economy. “Modern young Americans seem bound to face a world stamped by ever narrowing opportunity and social stagnation(停滞),”noted The Daily Beast.

    “The rate of 16-to 24-year-olds out of school and out of work is unusually high at 15%. Many college graduates have taken jobs that don't require a degree,” Time reported.

    The magazine worries that these difficulties may lead to a lost generation who are “unable to ever truly find their feet on the corporation's ladder”.

    Dan Kadlec, a reporter of Time, sees Millennials as resetting their expectations.”This situation is different for young adults today,” he wrote. “A true American dream has to feel attainable, and many Millennias are feeling they can only attain a day-today lifestyle that suits them.”
