gmatcoin以太坊
⑴ gmatcoin是网络诈骗吗
从微信上订的草莓,收取定金打了1000元未给发货,一般是民事纠纷,不算网络诈骗。
⑵ GMAT语法more than机经知多少
1. 考了more by....rather than by ....
选项有
than by,语法君帮大家分析下吧,跪的答案就不干扰大家了。应该就原题和这个之间选,其他都好像都不对
考点分析:
1) More ... rather than ;More ... instead of ;More ... as…; 比较级 + over
都是错误的用法 From Manhattan SC
2) 主语比较: A do sth than B do.
AB为对等名词,加do是为了显示这是一个可以发出动作的名词,因而确定是主语,进而确定是主语对比)
介宾比较: A do sth of C1 by D1 than of C2 by D2.(C1C2,D1D2对等名词)
理论上介宾短语比较一定要补出介词,否则容易造成歧义;但是具体情况要看选项,并不能作为Split
宾语比较: A do C1 than C2.(C1C2为对等名词)
状语比较: A do sth than usual/everbefore/people expected(直接加状语)
3)顺便Refresh一下Rather/rather than 用法
- 记得在哪里看过,rather 几乎可以接任何东西。
- Rather,是副词,单独出现表转折时一般都在句首,用逗号隔开,接句子,不能接to
do,也不能直接跟句子。而且一般不会单独出现语法SC-133d0h
- 介词短语作状语时,要么提到句首,要么放在动词之后
- Neither … nor…, but rather 固定用法 OG13-74
语法SC-133d0h One critic's response to the philosopher's new work is not that
the position it takes is heretical, as some have asserted, but rather that it is
nothing new to anyone who knows anything about the topic.
OG13-74 Although it covers the entire planet, Earth’s crust is neither
seamless nor stationary, but rather fragmented into mobile semi-rigid
plates.
下面附上相关例题2道
Prep07-1的106题是这么说的
Officials at the United States Mint believe that the Sacagawea dollar coin
will be used more as a substitute for four quarters rather than for the dollar
bill because its weight, only 8.1 grams, is far less than four quarters, which
weigh 5.67 grams each.
(A) more as a substitute for four quarters rather than for the dollar bill
because its weight, only 8.1 grams, is far less than
(B) more as a substitute for four quarters than the dollar bill because it
weighs only 8.1 grams, far lighter than
(C) as a substitute for four quarters more than for the dollar bill because
it weighs only 8.1 grams, far less than
(D) as a substitute for four quarters more than (for )the dollar bill
because its weight of only 8.1 grams is far lighter than it is for
(E) as a substitute more for four quarters rather than for the dollar bill
because its weight, only 8.1 grams, is far less than it is for
句子结构:Officials believe that the Sacagawea dollar coin will be used as a
substitute for… more than for… because it weighs…
主语是officials,谓语是believe,宾语是由that引导的宾语从句。
考点:比较、指代一致
比较,less/more + adj. … than… ,比较对象要对等,介词不可省略;more… than 经常会出现rather
than作为混淆;如果比较结构中的than前面有多个名词,than后面需要补充出介词以避免产生歧义。
指代,单数代词it在句中指代出现过的名词,要注意逻辑意思是否合理。
(A) more… rather than 搭配错;its weight和后面four quarters比较对象不对等。
(B) more as… than the dollar,the dollar和前面比较对象有歧义。
(C) 正确,介词短语a substitute for… more than for…形式上并列。
(D) more than 后面省略介词for使句子产生歧义;it没有指代对象,根据句意it应该指weight,不能指代its
weight,因为原句是将dollar的 weight和for
quarter的weight进行比较,两个weight不同,如果用it指代,则不符合逻辑。
(E) more… rather than 搭配错;it没有指代对象,根据句意it应该指weight,不能指代its weight,
Gone are the sharp edges and jutting planes of styles from former eras;
instead, designers of everything from cars to computer monitors have adopted a
corner less style of smooth surfaces and curves that is more ergonomic,
conforming to the shape of the body rather than flaunting shape for its own
sake
(A) more ergonomic, conforming to the shape of the body rather than
flaunting shape
(B) more ergonomic, conformed to the body's shape and not to flaunting
shape
(C) ergonomic, more conformed to the shape of the body and not to shape
flaunted
(D) ergonomic, conforming more to the body's shape rather than shape
flaunted
(E) ergonomic, conforming more to the shape of the body than flaunting
shape
翻译:前一个时代那种锋利的边缘和突出的面的风格已经过去了
句子结构:Gone are …; instead, designers… have adopted a style… that is …,
conforming to… rather than flaunting…
That is定语从句修饰单数名词style,并列的现在分词结构conforming to… rather than
flaunting…作状语修饰is more ergonomic。
考点:逻辑表达、平行对称
1) 逻辑表达,原句中的副词位置不能随意改变。
2) 平行对称,选项中如果都包括连接并列成分的连词,如rather than, but,
and等,要注意对比各选项之间并列成分的区别,是否保持了原句要表达的意思。
(A) 正确,conforming… rather than flaunting…是现在分词作状语修饰前面的句子that is more
ergonomic。conforming和flaunting 的平行
(B) 用过去分词conformed表示被动,不符合逻辑意思;and后面的to shape...与to the shape of the
body并列对象错误。
(C) more位置改变,改变了原句意思;rather than连接对象不对称。
(D) more位置改变,改变了原句意思;and后面的to shape...与to the shape of the body并列对象错误。
(E) more位置改变,改变了原句意思;more…than错误搭配改变了原句意思。

⑶ GMAT数学备考你需要注意的几个问题
GMAT数学备考要注意什么?
一、语言问题
在GMAT考试数学部分的解题过程中,题目语言通常是国内考生们首先需要面对的大问题。即使题目本身仅仅相当于中国初中数学水平,但一旦使用复杂的英文语句去阐述,同学们往往搞不清数量之间的关系。但对于语言问题,如果更加细分地去区别到底题目语言的难点在哪里的话,会发现一般可分为三类:第一、英文词汇不够;第二、数学词汇不够;第三、数量关系的表达方式不熟悉。
第一类问题所造成的错误,主要体现在考生不知道某些英文名词的意思,从而完全不清楚题目所描述的事物是什么或过程怎样进行。例如下面这道例题:
例1:A quarter, a dime, a nickel, and a penny are placed in a box. One coin is
drawn from the box and put back before a second coin is drawn. In how many
different ways can two coins be drawn so that the sum of the values of the two
coins is at least 25 cents?
A. 9 B. 7 C. 6 D. 5 E. 4
题目问有多少种方式两种硬币之和至少25分。如果学生不清楚quarter、dime、nickel和penny分别对应着25美分、10美分、5美分和1美分,则很难能做起这道题。要解决这类问题,学生需要更大量的单词积累。就数学而言,学生尤其要重视一些常出应用题的知识模块,其周边的单词非常重要。例如概率问题中与赌博相关的单词,硬币的两面head和tail、骰子die和dice、扑克的花色spade、heart、diamond和club等等。
第二类数学单词的问题,学生必须在考试准备的最初阶段就完全解决。而复习的方式就是认真背诵数学单词表。在记忆过程中,需要着重记忆单词的数学含义,最好能将知识的复习融入其中,并且要重视记忆复数形式和多义词,例如vertex的复数形式是vertices,radius的复数形式是radii。
例2:Which of the following fractions has an equivalent decimal that is a
terminating decimal?
A. 10/189 B. 15/196 C. 16/225 D. 25/144 E. 39/128
此题含有大量数学单词,题目意思是下面哪个分数的恒等小数是有限小数。其中terminating
decimal很多学生并不清楚表示有限小数。由于GMAT不能使用计算器,因此如何快速找到答案也是我们在GMAT数学考试中需要具备的能力,由于是否为有限小数由分母决定,分母含有3或7的最简分数一定不是有限小数,因此A、B、C、D都能快速排除,选择E。
第三类语言问题,主要是一些短语对于数量关系的表达学生并不清楚。例如:
例3:There are three type of pencils, J, K, and L, cost $0.05, $0.10, and$0.25
each, respectively. If a box of 32 of these pencils costs a total of $3.40 and
if there are twice as many K pencils as L pencils in the box, how many J pencils
are in the box?
A.6 B.12 C.14 D.18 E. 20
对于“there are twice as many A as
B”这种句型,学生通常会迷糊到底是A=2B还是2A=B。这里A=2B才是正确的理解,从而可以表示出K=2L,J=32-3L,利用总价格可以得到一个一元一次方程,算出L为6,得到答案J=14。
二、逻辑问题
GMAT作为商科研究生的考试,非常重视对于学生逻辑的考查,在数学部分体现为对于符号逻辑和条件逻辑的考查。尤其是GMAT数学中所独有的Data
Sufficiency题目,对于学生逻辑思维的考查远甚于对于数学知识的考查。对于这类题目,学生首先需要时刻清醒认识的是,题目到底问什么?因为你需要判断条件是否能充分回答问题。因此,如果问题问的是what,那么答案必须有且仅有一个值,才算条件充分。如果问题是一般疑问句,条件既能回答yes又能回答no,那算是不充分。但如果只能回答其中之一,无论yes或者no,都算条件成立。而这类问题中,尤以不等式的Data
Sufficiency题目最有难度。
例4:If x and y are positive integers, is x>y?
(1)
(2)
注意到,题目是一个一般疑问句,条件(1)或(2)只要能确定得到x>y或者x,所以单独(1)条件能判断。第二个条件只能得到,x是否一定大于或小于y呢?可以代入特值来判断,例如若x=4,y=3满足(2),若x=2,y=3也满足(2),因此无法断定x一定大于或小于y。此题选A。
三、知识问题
一般而言,GMAT所考查的知识范围,中国学生应该掌握得都不错。但仍然需要对整个知识进行系统地复习,尤其是小学和初中学的算术部分,以及概率统计的相关知识,特别要注意对于知识细节的梳理。对于长期在国外学习的学生,或者一直以来数学成绩不怎么理想的学生,需要在这方面花费远多于其他学生的功夫进行复习。下面这道题就是对于知识细节的考查:
例5:If set S consists of ten distinct positive integers, which of the
following could be a member of S?
I. The mean of the members of S
II. The median of the members of S
III. The mode of the members of S
(A) None
(B) I only
(C) II only
(D) I and III
(E) II and III
这道题需要学生清楚mean,median和mode的定义,并且需要知道和仔细思考定义中的一些细节。众数mode除了知道表示出现次数最多的数,还要知道当所有数个数一样多时,众数是不存在的,因此一定不在S中。中数median在个数为偶数时,表示中间两个数的平均数,由于10个数都不同,则其中两个数的平均数肯定不等于中间任意一个。只有mean有可能会等于其中之一,由于问题用的could而非must,所以选B。
