@徐小梅老师，徐老师您好，第4)题，我也看到了“至少2人”这个字眼，也是按照至少2人来算的。但我是这么理解的：原来男女共有12个人，先从5个女生中取2个人，保证了至少有两个女生，所以是C5^2; 接着，再让剩下的3个女生和7个男生合并，共10人，取3个人（此时不论男女都可以），是C10^3。然后合起来就是C5^2*C10^3。

我能判断出的： A . but also 单独出现的时候表示转折（不太确定这里） B. 留着了，B让我看着不顺的地方是 主句的also 感觉是和前定从呼应，说不上是什么错，但.. C. 原因状从because 后不是完整句子 D. 比较对象不一致， 应该是...as the Moon (has) E. 我选了E，感觉句子说的很清晰，唯一心有余悸的就是这个so, 选的时候 把so 当做了副词看 问题： 1.E的不好是因为 so 表示“所以”的意思时，是连词要连接2个完整句么？ 2. 请老师讲解B 也欢迎纠正我做题思路的错误 多谢❤️！

如果一个句子里面有过去时和现在完成时，这两个动作哪个是先发生的？ 如果一个句子里面有过去时和过去完成时，这两个动作哪个是先发生的？ 如果句子中间是用；分开的的两个句子时态还会相互影响吗？ 这个题目里面after是介词不是时间状语从句对吗？

"思路： -觉得同位语比which好，排除AB -D的that was not successful有歧义 因为可 修饰到kings或者是achievement 上；排除 -CE里面 觉得C好 but后面虽然省略了主语 但这句的主语就只有other S kings"；it就是指前面的那个事，觉得没毛病； 我的问题是：（1）C这里没有E好的的原因是 but之后没有主语么 ？（2）E里面 "without success"修饰的是谁呢？是other S kings， 还是other S kings的这个动作？像 主谓宾 with xxx这种结构，with在最后的话 一般修饰的是啥？ 谢谢老师！

Years before the advent of plate tectonics―the widely accepted theory, developed in the mid-1960's, the holds that the major features of Earth's surface are created by the horizontal motions of Earth's outer shell, or lithosphere―a similar theory was rejected by the geological community. In 1912, Alfred Wegener proposed, in a widely debated theory that came to be called continental drift, that Earth's continents were mobile. To most geologists today, Wegener's The origin of Continents and Oceans appears an impressive and prescient document, containing several of the essential presumptions underlying plate tectonics theory: the horizontal mobility of pieces of Earth's crust; the essential difference between oceanic and continental crust; and a causal connection between horizontal displacements and the formation of mountain chains. Yet despite the considerable overlap between Wegener's concepts and the later widely embraced plate tectonics theory, and despite the fact that continental drift theory presented a possible solution to the problem of the origin of mountains at a time when existing explanations were seriously in doubt, in its day Wegener's theory was rejected by the vast majority of geologists. Most geologists and many historians today believe that Wegener's theory was rejected because of its lack of an adequate mechanical basis. Stephen Jay Gould, for example, argues that continental drift theory was rejected because it did not explain how continents could move through an apparently solid oceanic floor. However, as Anthony Hallam has pointed out, many scientific phenomena, such as the ice ages, have been accepted before they could be fully explained. The most likely cause for the rejection of continental drift―a cause that has been largely ignored because we consider Wegener's theory to have been validated by the theory of plate tectonics―is the nature of the evidence that was put forward to support it. Most of Wegener's evidence consisted of homologies―similarities of patterns and forms based on direct observations of rocks in the field, supported by the use of hammers, hand lenses, and field notebooks. In contrast, the data supporting plate tectonics were impressively geophysical―instrumental determinations of the physical properties of Earth garnered through the use of seismographs, magnetometers, and computers. 我选了E considerable overlap前面是despite XXX说明这个是个成就，他和后面的反对W的观点的事情是相反的。所以感觉D说用这个词的目的是解释为啥W理论。请老师辨析DE！谢谢！

希望May老师回答一下，我理解的题目意思是有v又有c的是1/30，有v的total是1/10，那么有v没有c的是2/30。有c的total是1/5，那么没有c的total是4/5，所以没有c也没有v的是（4/5-2/30）=11/15，可是给出的答案是A，不知道哪里搞错了。

A选项D选项动作发出者分别是什么A为什么不对 这个题能帮忙分析一下吗

请数学老师解答一下 谢谢 答案是星期四十点 我只能算出星期四12点

老师，对于这题ABC的their还有DE的they.他们指代有没有问题呢，就近的话我可以理解成指代records吗The loan company announced it would soon lend money to borrowers with proven records of their not paying back their loans on time,collectively known as subprime lending market. A.of their not paying back their loans on time B.of not paying back their loans on time, a group C.of not paying back their loans on time,with such a group D.that they do not pay back their loans on time. E.that they do not pay back their loans on time,such a group

图片里的并列不是很明白，还得麻烦老师帮忙将一下谢谢，此外， 下面这and连接的并列，不考虑语义，前面是过去分词，后面是it+过去分词这种属于并列吗？brightened the Northern Lights and it possibly knocked

本题是og19、sc720题，答疑器搜不出来，有如下疑问，谢谢老师 ①A选项不太明白， ②so as to 有没有这种说法？ ③D选项的enough和so as to能连用吗 ④E选项的so much as to有这种说法吗
