考研英语是所有备考科目中比较难的科目，语法长难句部分更是重点，所以拿下这部分很关键。为此，小编整理了“2020考研英语：100个经典长难句解析(十)”希望对大家有所帮助。
91. Recently, there have been some imaginative attempts to make polycrystalline and ribbon silicon which are lower in cost than high-quality single crystals; but to date the efficiencies of these apparently lower-cost materials have been unacceptably small. ，有些人试图研制多晶硅和带状硅，这些材料比高质单晶硅成本小，但是，迄今为止，这些成本明显小的材料的效能低得不实用。
92. Although many scientists were aware of the very low cost of amorphous solar cells, they felt that they could never be manufactured with the efficiencies necessary to contribute significantly to the demand for electric power. 许多科学家虽然已经认识到非晶硅太阳能电池的低成本，但是他们也感到，要生产出这样的电池并使之产生足够的功效、在很大程度上满足对电能的需要，是不可能的。

93. Already, solar cells with efficiencies well above 6 percent have been developed using amorphous materials, and further research will doubtlessly find even less costly amorphous materials with higher efficiencies. 用非结晶体材料研制的太阳能电池的使用功效已经远远超过6%，未来的研究必将找出成本更低的但功效更高的非结晶体材料。
94. This imaginary task gives some idea of the challenge facing biologists in the United States and elsewhere as they embark on a monumental project: deciphering all the coded information in the human genome, all the genes in a human cell. 美国和世界各地的生物学家面临一项重大工程的挑战，这个假想的任务使人们对这个挑战的强度获得一些认识，这个挑战就是：破译人体基因组中的编码信息。
