可不可以用这种思路?抽的第一个人可以从10个人里面选,抽的第二个人本应该从剩下的9个人里面选,但是其中有一个是夫妻,所以只能从剩下8(9-1=8)里面选,第三个人只能从剩下6(7-1=6)个人里面选,所以一共有10*8*6种排列方式,但因为这是组合问题,所以要除以不同选择顺序的总数,即3*2*1,所以一共有(10*8*6)/3! = 10*8=80种
相当于是运用了乘法原理来做的
cool,我跟你一个方法,看到你的评论我放心了很多
now: the value of H is more than 25% of debt, it covers all debt still leaves 25%
if the selloff causes price plunge: the value of H down 25%, value of H becomes 125%*75%=375/400<100% of debt, can not cover all debt
主要是要echo前面“can be planned”被动结构吧
时态不一致,不能省略
Some buildings 【that were destroyed or heavily damaged in the earthquake last year】 had been constructed {in violation of the city's building cede.}
39897约等于40000。 不是4000
because of this ideaology, women are marginalized because their contribution are omitted in the eyes of the male-domi unions.
A D只有两句话, 谁主谁从都可以, 错在时态
C 选项 同时发生 所以伴随优于并列
老师,请问E选项,为什么first made in 1845 作定语呢?
问is x>2 ?
选项一:x=1、2、5等
选项二:x=1、2、3、4
所以C:x=1、2时,is x >2不成立,充分
题目求4m+6n,条件2告诉你2m+3n=55,选B

Gusty westerly winds 【will continue】 to usher in a seasonably cool air mass into the region, as a broad area of high pressure 【will build and bring】 fair and dry weather for several days.没有用主将从现❌
B
【Gusty westerly winds will continue ushering in a seasonably cool air mass into the region】 and 【a broad area of high pressure will build that bring fair and dry weather for several days】❌
Gusty winds 先把冷空气团带进了地区,形成了冷高压,是这个冷高压导致了几天晴朗(fair)干燥的天气
C
Gusty westerly winds will continue to usher in a seasonably cool air mass to the region, a broad area of high pressure building, and bring fair and dry weather for several days. a broad area of high pressure building作为插入语❌
D
Gusty westerly winds will continue ushering a seasonably cool air mass in the region, 【with a broad area of high pressure building】 and 【bring fair and dry weather for several days】and前后明显不平行❌
E
Gusty westerly winds will continue to usher a seasonably cool air mass into the region while a broad area of high pressure builds, which will bring fair and dry weather for several days. which修饰"a broad area of high pressure"✔
为什么C不对
看了半天,我少看了条件 ...
This year city services will separate for recycling enough refuse to reduce the number of truckloads of refuse to be incinerated to half of last year's number
这就话说will..... will是100%的意思 ... 所以E 选项才会被排除 。这句话意思就是无论如何,今年用来燃烧的truckload的数量将会被减到只有去年的一半....垃圾多了,少了,都会被控制到去年一半
所以在这个前提下,才有D的合理性 X(ash总量)= M (truckload数 )* N(单位车产生的ash ) .... 1/2 X = 1/2 M * N
没有这句话,D和E选项就是一样的 ,就成了数学题,必须有个参照数据才能决定哪个效果大
看了一圈下来,我觉得你的解释是最有道理的,关键是在于对这句话的理解。OG对E项的解释感觉不好。

为什么主句不用虚拟语气呢
between and 包含两边
归因:没读懂
C that 指代fidelity
五句话是3种不同的意思 A C的意思比较合理
A 比较对象错误
