ing伴随要么表示伴随的动作,要么表示伴随的结果。表示伴随的动作时,要求: (1)动作跟随主句主语;(2)与从句的动作在一个时间框架里;表示伴随的结果时,要求是主句动作的直接的、自然而然的结果。
A,appear和vanish不在一个时间框架上,不能伴随发生,(总不能伴随着自己的消亡出现吧?)
the rate of mainstream American businesses failing is,介词+doing的情况,of的对象是名词businesses,即the rate of businesses,错误;the rate of mainstream American businesses's failing则核心词是动作failing,the rate of failing
if it's not表示如果不是,则是;instead是副词,表示相反地,却。If it's not A, instead it's B构句法上一主一从是没有问题的,但语意上是冗余的。
要用instead的话,改成:It's not A, but instead it's B
倍数的比较:as/as, than或直接+名词,直接+the number of 名词
D,the rate of fatty food consumed…可以指脂肪食物自己有一个rate,也可以指是这个rate被consumed了,应该用the rate at which fatty foods consumed…
D相比B去掉了consumed的动作主体people,主体明晰是更好的,比如the rate of fatty foods consumed in France没有说是consumed by people,那被食肉动物消耗的fatty food也可以算进去咯?
E,the rate of people consuming fatty foods,核心是名词people,即people‘s rate,如果要让动作做核心,改成the rate of people's consuming fatty foods
remain,可以做系动词,remain adj,保持某种状态;sth remain sth,仍然是……,如:they remain the best of friend,他们仍然是好朋友;life insurance remained a specialized contract,人身保险仍然是一个特定的契约
求问为什么不考虑AB相交呢,如果相交,1+2求出p(A)=0.7啊
ctm新题永远做错 能做对的都是记得住答案的 我不活了
range of the positive integers in list K 求的是正整数的值域 即集合里面所有>0的数的和
imitations of designers and crafters表示针对这些人的模仿,模仿这些人;应该用designers' and crafters' imitations
C,not until 19th, they have inspired时态错误。改为had inspired或inspired
until表示在……之前动作的持续。直到过去,用过去完成时或过去时;直到现在用现在完成时或现在时;直到未来用一般现在时或现在时。如:
They moved here in 2002, Until then they'd always been in the London area.
He continued working up until his death.
Until now I have always lived alone.
Let's wait until the rain stops.
You're not going out until you've finished this.
没说blocks都一样大,所以不能判断
Cubical立方体,不是正方体,不知道每个cubical的规格
百度立方体,得到:“立方体,又称正方体”
感谢指正,谢谢!
不用谢
每个都是Cubical block,但是可以一个是4*4,另一个是3*3
b选项:resulting in wood ,逻辑语义错误
难道是有5就行?
第一轮,三个都可以:3分之3
第二轮,只有两个可以:三分之2
第三轮,只有一个可以:三分之1
相乘
c
m小于0,mv小0,则,v一定大于0
2
已经说明x是负数了,则表明一定不为3
p的1
次方和t的4次方也符合1
