突破SAT阅读长难句是拿高分的重点

　　SAT阅读要想拿高分，重点是突破SAT阅读长难句，而长难句的学习是一个持之以恒、熟能生巧的过程，所以我们不断地给大家讲解，也是希望大家能够在每天的练习中总结方法和技巧，能够有所收获。

　　1. Studies by Hargrave and Geen estimated natural community grazing rates by measuring feeding rates of individual zooplankton species in the laboratory and then computing community grazing rates for field conditions using the known population density of grazers.

　　由哈格雷夫和吉恩所进行的研究，对自然条件下的群落捕食速率进行了估计，其手段是通过测量出实验室内单独的浮游动物种类的捕食速率，然后利用已知的食草动物种群密度，计算出实地状况下的群落捕食速率。难句类型：复杂修饰

　　2. In the periods of peak zooplankton abundance，that is，in the late spring and in the summer，Haney recorded maximum daily community grazing rates，for nutrient-poor lakes and bog lakes，respectively，of 6.6 percent and 114 percent of daily phytoplankton production.

　　在浮游动物数量激增的高峰期，亦即在春季后期以及夏季，哈尼记录了最大程度上的每日群落食草比率，对于营养物不充足的湖和沼泽湖而言，分别为每日浮游植物繁殖量的6.6%和114%.难句类型：插入语

　　3. The hydrologic cycle，a major topic in this science，is the complete cycle of phenomena through which water passes，beginning as atmospheric water vapor，passing into liquid and solid form as precipitation，thence along and into the ground surface，and finally again returning to the form of atmospheric water vapor by means of evaporation and transpiration.

　　水文循环，作为该学科中的一个主要课题，指的是水所经过的诸现象的整个循环过程，开始时是作为大气中的水蒸气，转而作为雨、雪、露、雹一类的降水量经过液体和固体形态，由此而沿着地层表面分布或进入地层表面，最终通过蒸发和散发作用再度回复到大气水蒸气的形态。难句类型：复杂修饰、插入语、省略

　　4. Only when a system possesses natural or artificial boundaries that associate the water within it the hydrologic cycle may the entire system properly be termed hydrogeologic.

　　只有当一个系统拥有自然的或人工形成的边界来把边界中的水与水文循环联系起来的时候，才有可能把整个的系统恰当的成为与水文地质学有关。难句类型：复杂修饰、倒装

　　5. The historian Frederick J. Turner wrote in the 1890s that the agrarian discontent that had been developing　steadily in the United States since about 1870 had been precipitated by the　　closing of the internal frontierthat is，the depletion of available new land　needed for further expansion of the American farming system. 史学家弗雷德里克.杰.特纳于十九世纪九十年代著述道，美国约自18世纪70年代以来一直在持续不断发展的农民不满，由于国内边远地区的封闭而更趋加剧亦即是说，美国农业系统进一步扩展所必需的可资利用的新土地几近耗竭。
