语法： 只有一道明显的either or的平行考点，其他的都是一些句子都读不懂的2行的怪题，其中有一道so as to的考点，但是其他的选项都没有so，特别的奇怪。。。好想吐槽，运气是有多差。。。！！！！！然后都是用语义解题，找最简洁的。。。（考点：简洁有效--吐槽啊！！） 想起来一道： 是平行比较 是protion of people和另一个人口比例的比较（另一个的表述忘记了，反正找比率VS.比率）
【参考资料】 In the 1980's, astronomer BohdanPaczynski proposed a way of determining whether the enormous dark haloconstituting the outermost part of the Milky Way galaxy is composed of MACHO's(massive compact halo objects), which are astronomical objects too dim to bevisible. aczynski reasoned that ifMACHO's make up this halo, a MACHO would occasionally drift in front of a starin the Large Magellanic Cloud, a bright galaxy near the Milky Way. The gravity of a MACHO that had so drifted,astronomers agree, would cause the star's light rays, which would otherwisediverge, to bend together so that, as observed from Earth, the star wouldtemporarily appear to brighten, a process known as microlensing. Because many individual stars are ofintrinsically variable brightness, some astronomers have contended that the brighteningof intrinsically variable stars can be mistaken for microlensing. However, whereas the different colors oflight emitted by an intrinsically variable star are affected differently whenthe star brightens, all of a star's colors are equally affected bymicrolensing. Thus, if a MACHO magnifiesa star's red light tenfold, it will do the same to the star's blue light andyellow light. Moreover, it is highlyunlikely that a star in the Large Magellanic Cloud will undergo microlensingmore than once, because the chance that a second MACHO would pass in front ofexactly the same star is minuscule.
