ticked和exceed speed limit regularly 是否等于? 选项B补充了这个gap,压根跟数字没关系啊迷惑
E说新机器替代旧机器,但是不知道新机器需要花多少钱,有可能还花的更多,所以不能说明剩下的钱会变多。
B雇了没训练好的新员工,所以accidents per employee不会因为花钱多了就lower, 削弱结论
单词要命啊
B错误,第一句并没有support第二句表达的strategy,很明显是不同的strategy
E错误,goal是large profit,显然第一句并没有reject这个goal。
还是题目没有理解到位,公司的目的是扩大利润,开始提出了一个strategy,然后说这个strategy不行,最后提出一个认为可行的strategy
B重复了题目前提,只是换了个说法。
C说明如果每间新公司提供的工作不如去年的新公司多的话,那肯定需要提高新公司的数量才可以有破纪录的total number。number of companies 和 record job created 中间就差个 job per company
C选项说明火山爆发和天气寒冷无绝对因果关系
D说的是any programme,题目说的是special programme,所以其实是无关项
要收到special programme有两个条件:1. 在RDS radio station范围内 2. radio带RDS功能。题目只说了因为条件2没变所以收到的人没变,但忽略了条件1.
选项A取非说明了因为增加了radio station,所以很多有RDS功能的radio只不过是因为以前不在station范围内,现在在station范围了那就收到了,即收听到special programme的人会增加。取非削弱了结论。
一些经济学家认为,7月份的失业率下降至两年来的最低水平,表明就业市场的逐步改善正在继续。
premature 过早的
所以选项是要选可以削弱 the rapid development of new fields will result in higher oil exports
错选B,每株长的更高就想当然每株产量会高,但是忘了题目前提是lower yields per plant
(1)∠BDC=∠BAD + ∠ABD 2x=x+∠ABD,DAB和BDC均为等腰三角形。
(2)X=36 不能 只有度数,没有长度,无法推,不充分
c选项定位:Four critical genes governing circadian cycles have been found to be active in every tissue, however, not just the SCNs, of flies, mice, and humans. In addition, when laboratory rats that usually ate at will were fed only once a day, peak activity of a clock gene in their livers shifted by 12 hours, whereas the same clock gene in the SCNs remained synchronized with light cycles. 四个控制昼夜周期的关键基因被发现活跃在每一个组织中,然而,不仅仅是在苍蝇,老鼠和人类SCN中。此外,当通常随意进食的实验室大鼠每天被喂食一次时,肝脏中时钟基因的峰值活性移动了12小时,而SCNS中相同的时钟基因则与光周期保持同步。
这就说明scn并没有控制许多组织和器官的时钟基因,它可能只能保证控制它其中的时钟基因。
e选项说的是这个scn受其他外部因素影响比受光线影响因素要多,这是错误的。因为是scn和其他外部因素影响生物周期,而不是SCN被影响。
这里说个计算捷径——(从gmatclub 来的)
Shortcut to multiply numbers of the form (100 + a) or (100 - a)
Write a2a2 on the right hand side. Add a to the original number and write it on left side. The square is ready.
e.g. 1082=(100+8)21082=(100+8)2 Write 64 on right hand side
________ 64
Add 8 to 108 to get 116 and write that on left hand side
11664 - Square of 108
e.g. 912=(100−9)2912=(100−9)2 => ______81 => 8281
(Here, subtract 9 from 91)
Note: a could be a two digit number as well.
e.g 1122=(100+12)21122=(100+12)2 = ______44 => 12544
(Only last two digit of the square of 12 are written on the right hand side. The 1 of 144 is carried over and added to 112 + 12)
This is Vedic Math though the trick uses basic algebra.
(100+a)2=10000+200a+a2(100+a)2=10000+200a+a2
(100 + 8)^2 = 10000 + 200 x 8 + 64 = 10000 + 1600 + 64 = 11664
This is a useful trick that saves time.
(2) (1 + r/100 )^2 > 1.15 --> if r=8 then (1+r/100)^2=(1+8/100)^2=1.08^2≈1.16>1.15
so, if r is slightly less than 8 (for example 7.99999), (1+r/100)^2 will still be more than 1.15. So, this statement is not sufficient to say whether r>8.
must be true
A. 通过wasp的behavior能够确定 能产蛋的hostage的最小size,正确
(小于这个size的不产蛋,大于这个size的有蛋,故这个范围值可以确定)
A. 并没有identify the origin
C. a commonly held belief = because wages are lower in developing countries than in developed countries, competition from developing countries in goods traded internationally will soon eliminate large numbers of jobs in developed countries.
b,lighting still provided mainly by candles-句子结构不完整,缺少谓语
c,where lighting was still being + where引导的noun modifier离修饰的主语homes太远
d,there was less than one percent of homes that had electricity,主谓不一致,there were less than one percent of homes
e,同c,where引导的noun modifier离修饰的主语homes太远,where就近修饰electricity【曼哈顿上说noun modifier需要和修饰名词尽量靠近,adv modifier主要不产生歧义,可以和修饰的adj/verb有距离】
综合来说a是最优选,其他选项都有明显错误
B. 主语是their descendants,变成了descendants released the honeybees,错误
C. 两个过去完成时,错误
D. when错误
E. and错误
A. 最高法院是强调了“国会”在土著问题上至高无上的单边权利,不是最高法院的地位增加
C. abandoned negotiation and execution of formal written agreements = no longer needed to conclude a formal agreement
逗号ing 不是应该修饰上一句的主语吗 不是union members 吗?
