In the country of Veltria, the past two years' broad economic recession has included a business downturn in the clothing trade, where sales are down by about 7 percent as compared to two years ago. Clothing wholesalers have found, however, that the proportion of credit extended to retailers that was paid off on time fell sharply in the first year of the recession but returned to its prerecession level in the second year. Which of the following, if true, most helps to explain the change between the first and the second year of the recession in the proportion of credit not paid off on time? (A) The total amount of credit extended to retailers by clothing wholesalers increased between the first year of the recession and the second year. (B) Between the first and second years of the recession, clothing retailers in Veltria saw many of their costs, rent and utilities in particular, increase. (C) Of the considerable number of clothing retailers in Veltria who were having financial difficulties before the start of the recession, virtually all were forced to go out of business during its first year. (D) Clothing retailers in Veltria attempted to stimulate sales in the second year of the recession by discounting merchandise. (E) Relatively recession-proof segments of the clothing trade, such as work clothes, did not suffer any decrease in sales during the first year of the recession. 这道题错选了A。 思路如下： 题目问的是为什么在经济不好，衣服卖不动的情况下，第一年零售商还不上钱第二年就能还上了。讲的是零售商还钱的问题。 当时留下的是A,C,D 排除D是因为觉得，即使刺激销售量衣服打折也不能说明能还上钱。可能打折卖1块，纵使家当全卖了也不够。 排除C是因为觉得， 那些本身经济状况就很差的在第一年被淘汰掉以后，剩下的那些没说经济状况如何啊，如果也不咋地，第二年还是得淘汰啊。 A选项当时觉得，即使credit extended，对pay off on time也无太大用处，但最起码跟原文意思接近。所以选了A。

请问当遇到这种完全看不懂不明白逻辑关系的题怎么办？可以帮忙分析一下这篇文章吗

011我是把去银行放进了第一个、第二个、第三个然后分别去算它的可能性，我算出来是10种诶，不太懂为什么答案是12种

请金老师帮忙回答下 七龙珠E卷 34 考点： 并列，时态 我自己选的A， 理由：划线外are often dragged under and drowned的 主语that指的就是seabirds， 语义，并列都符合，虽然用的是encountered但是感觉可以接受 给出的答案C，说长线 devastating 海鸟 are often dragged and drowned. 感觉从修饰结构能接受，但是句意不是很理解

请金老师帮忙回答，七龙珠E卷的 32题 考点： 修饰，分号与逗号 读完句子直间排除了BCD， 保留了A，E,做题时没有注意到分号， 是否因为it appears darker是有完整主谓，E不能直接逗号接从而排除

七龙珠E卷的16题 请金老师帮忙解答： 可以看出考点：修饰，指代，时态 根据副词修饰形容词排除了AB， CDE选项，我能看出考点，但是缺选不对答案，比如我知道考点是指代，但是我无法判断percentage of it这个加上到底好不好， 再比如我能注意到 estimated that, 会认为需要用将来式，但是做题的时候感觉读C更顺，而选择C 实际做题的时候，应该怎么结合看出来的考点提高正确率呢？

请问什么时候用从句，什么时候用svo+doing呢？

请问"and consequently"的意思和作用与“and thus" 或“and also"是一样的嘛

since Robert boyle是什么意思怎么感觉怪怪的？所以这道题就是关注语义形式并列而不是看功能并列嘛？还有就是and also到底可不可以用？
