不懂D为什么错……

veritas的语法视频里老师说being表示暂时的状态，不知道老师可以不可以这么理解？

e选项没有缺少一个the吗？melting直接就跟a rise平行了，难道是因为of吗

老师，E选项不是并列的吧？

A：要保证样本数量足够

？？？

choice b is badly worded: 'compares to 42 times in 1980' seems to say that, on forty-two different occasions in 1980, the ceo:blue-collar ratio reached 419:1. this is not what we are trying to say.

but you can't just leave "42 times" hanging out alone.

percentages, on the other hand, can be referenced by themselves (as long as context, somewhere else, clearly indicates what the percent is of).
for instance, you can say "80% of the X's are male, up from 67% five years ago". here, the second percentage is understood to be also "of the X's".

you can't just write "42 times" by itself. it has to be 42 times something.
if it's 42 times something that was mentioned previously, or 42 times something that is in parallel structure to something that was mentioned previously, then you could use a relative pronoun (i.e., something like "42 times that in 1990", etc).

使用了代入法，不过此类题目真正的解法是什么？If x is an integer and y = 4x + 3 which of the following CANNOT be a divisor of y ?是一类吗？

3的幂次方个位数为1379循环

3^24=81^6 个位数1六次方还是为1，那么除以5，余数为1。【若问3^23，同理余数为3；若问3^86，3^86=9*81^21，因为81^个位数始终为1，乘以9，个位数始终为9，所以余数为9-5=4】。

one half the number of issues 意思是发行的数量比原来少了一半

needed to found new businesses就近原则修饰 “the contempt of risk and the presumptuous hope of success”，而who have ... 就近修饰 young people。

原文内容着重强调两种Skills的对比，如果选D，那么willing to admit that they lack computer skills or other technical skills就变为可删除的插入语，对比意思就不那么强烈。与D相比，C虽然有名词和动名词的区别，但是语法和语义上都表达的更为完整。所以，选C不是更好吗？

B选项，如果把annually的位置调整，比如as much as is emitted annually by...是不是也不对？因为is？

对so的理解错了，因为是代指前面整个行为。。
