1.(y平方-1）平方-1,所以就是y4-y2-1
2.（3*0.5+ 5*0.3+ 2*0.2）/10=0.34
3.y与x成反比,y=a/x,y =15 when x=5说明a=75,所以y=75/25=3
evanescence的意思是那种消失,幻灭,可句子后面用了个even though,说明要填相反意思的词,那就是存留的,没有消失的.seise是依法占有的意思,但还有个抓住的意思,这个还能靠得上边,但absolved是无罪的,根本和它没关系,所以不选A.
这句话里的while指的是即使的意思,与当···时候无关,所以evenif 后面的depiction的形容与stock意思相同,A选项第一个词是催眠的,与题意无关,所以选B.即使这个电影有了陈旧的记述,人们反驳说还是偏向理智的虽然描写有点格式化.
要理解tangent什么意思,指突然转移话题,所以与此相对应,这里应该是digress离题.
repudiation吧?这个句子的意思就是市长重新选举很多人支持不是因为大家支持他的政策,而是因为他反对批判了他对手极端的观点.
这个句子想说,不会有这样的先例存在：为了统一决定,法庭反过界打破法律的标准.需求和真实都和这个没关系.
光从pioneer和progenitor看不出什么大区别,两个都符合题意,关键是你要注意exploit多指开发,比如后面跟什么资源,项目,在这里要尽量和音乐挂上钩,比如句子里的drumming,所以mimic更能和句意贴切.
再问： 谢谢哈，但是那个关于音乐那道题我不是很理解为神马用乘法。我想的是用3除以0.5……算出每首歌时间，再加起来除以3
再答： 相当于总体唱了x首。 （3*0.5x+ 5*0.3x+ 2*0.2x）/(3x+5x+2x)，最后把x简化掉了 人家要求的是总体平均数，你理解的那个算法成了先算每部分的平均数，再来一次平均数。
