题目：

In the year following an eight-cent increase in the federal tax on a pack of cigarettes, sales of cigarettes fell ten percent.  In contrast, in the year prior to the tax increase, sales had fallen one percent.  The volume of cigarette sales is therefore strongly related to the after-tax price of a pack of cigarettes.

选项:

A、During the year following the tax increase, the pretax price of a pack of cigarettes did not increase by as much as it had during the year prior to the tax increase.
B、The one percent fall in cigarette sales in the year prior to tax increase was due to a smaller tax increase.
C、The pretax price of a pack of cigarettes gradually decreased throughout the year before and the year after the tax increase.
D、For the year following the tax increase, the pretax price of a pack of cigarettes was not eight or more cents lower than it had been the previous year.

Which of the following most logically completes the passage?
 
Appendicitis (inflammation of the appendix) is potentially fatal; consequently, patients with symptoms strongly suggesting appendicitis almost always have their appendix removed.  The appropriate surgery is low-risk but performed unnecessarily in about 20 percent of all cases.  A newly developed internal scan for appendicitis is highly accurate, producing two misdiagnoses for every 98 correct diagnoses.  Clearly, using this test, doctors can largely avoid unnecessary removals of the appendix without, however, performing any fewer necessary ones than before, since ______.
请陆旭老师回答一下。我选了C。因为我对C的理解是test不会将没有阑尾炎的人误诊成了有阑尾炎的人，换句话说就是误诊都是把有阑尾炎的人误诊成了没有阑尾炎的人。这样，医生至少是避免了不必要的阑尾手术的。而B和C的意思相反，说的是test的误诊通常是将没有阑尾炎的人误诊成了有阑尾炎的人。这样的话医生还是无法避免一些不必要的手术，没办法构成一个原因。请老师解答一下，感谢！

Coffee shop owner: A large number of customers will pay at least the fair market value for a cup of coffee, even if there is no formal charge. Some will pay more than this out of appreciation of the trust that is placed in them. And our total number of customers is likely to increase. We could therefore improve our net cash flow by implementing an honor system in which customers pay what they wish for coffee by depositing money in a can.

Manager: We’re likely to lose money on this plan. Many customers would cheat the system, paying a very small sum or nothing at all.

Which of the following, if true, would best support the owner’s plan, in light of the manager’s concern?
唐塘老师您好！问题中提到了两个人的观点，owner在前，manager在后。您在阅读课上说过，哪个在后面哪个就是重要的那个，是否符合这个题呢？感觉如果重心放在了manager的观点中的话，就不知道怎么选了...如果看owner的观点的话，目标在improve net cash flow，就能得知D正确，小吃点心这种其他业务带来了巨大的利润。详细讲一下好嘛~

In the first 2 hours after Meadow’s self-service laundry opens, m large washing machines and n small washing machines are in continual use. Including the time for filling and emptying the washing machines, each load of laundry takes 30 minutes in a large washing machine and 20 minutes in a small washing machine. What is the total number of loads of laundry done at Meadow’s self-service laundry during this 2-hour period?
  1. n = 3m
  2. 2m + 3n = 55
老师，这道题看到两个条件之后，一点思路都没有。根据提干，the total number of loads＝4m+6n, 我的理解是，只要能求出m和n的条件就是充分的。不知道我的思路哪里有问题？

Marconi's conception of the radio was as a substitute for the telephone, a tool for private conversation; instead, it is precisely the opposite, a tool for communicating with a large, public audience.
唐老师您好。我想问：A项可不可以这么排除：A的主语是conception，所以不能说conception是substitute；B可不可以这么排除：逗号后的提示词but后的代词which一定指代上一句中的主语Marconi，所以意思错了；E可不可这么排除：what it was违反简洁原则；C正确但我不明白instead后的it难道没有指代不清的问题吗？？
