这里首先需要读懂意思。最后一句话,当(假)的支票被电子扫描仪伪造出来,支票上会出现点点混合组成“假的”字样。C 完全无关,因为 C 根本没有提伪造的支票以及点点的事情。(c) is irrelevant, since it deals with what can be detected by the human eye (this is what "visually" means). the passage deals only with what can be detected by scanners, not by human eyes. https://www.manhattanprep.com/gmat/forums/general-availability-of-high-quality-electronic-scanners-t8440.html
100的倍数当中,x最接近于500,y最接近于400。问x+y最接近于100的倍数当中的哪一个?
The question is essentially asking why the threshold of economic viability has remained unchanged. In other words, why would the price of oil still have to hit $35 in order for solar powered plants to be a good idea? The best answer I can give is that the price of oil has nothing to do with how much the price *would* have to be in order for solar power to be viable. What would change my threshold of viability? NOTHING about the price of the oil can change the threshold.
1.(-x,y)唯一确定一个象限
由于(-a,b)(-b,a)在同一个象限,所以ab>0,且这两点可能在第二或者第四象限内;
找不到这个问题的信息点,哪里可以推出选项?
15的因数有3,5

笔记:错选C,还是要坚持大部分时候which只能紧跟前一个动词的原则,不要打破,所以which不能指代time;同时A--having...在剧中是修饰industrialization and...所以不能跟 gone unregulated (unregulated 的是pollutants).所以选B。
B选购的It 和them分别指代的是什么?
C 选项 the money is to be controlled by local school districts, but allowing it only to be spent;前半句时态问题同A ,另外is是约束力较弱的动词,不能连接 to do ,翻译成钱是去被控制的也不对啊;后半句有歧义如果but 连接的句子和同位语从句的前半句并列的话,allowing 的主语是the money,逻辑语义错;but 连接的句子和主干并列的话,allowing 的逻辑主语是the budget,语义也不对。
这个句子的主干是 The budget for education reflects the administration's demand,后面that 引导同位语从句。按照老师在“同位语”知识点写的 在某些名词(如demand, wish, suggestion, resolution等)后面的同位语从句要用虚拟语气。
我曹好开心这次skim第一次那么快的做题。。希望以后保持。。。
选项A even是副词,不能用作连词;foods have possibility 语义错误;have possibility for doing错误搭配
没看懂contentions是吵架的意思……另外做题速度真心慢啊…………
对比的是现在收集能源和以前收集能源,则the case in 1990是正确的对比
同问,非划线部分是its,为啥前面是用their和they呢?
E The average people 是说普通人,文章中很明显就是指特定的病的那部分人。
关注未划线部分,就可以排除ABC, initiating一定是california而不是consumption, 然后E中的per capita和per person重复,所以选D
