(44) “our total sales have increased this year by 20 percent since we added a pharmacy section to our grocery store. clearly, the customer’s main concern is the convenience afforded by one-stop shopping. the surest way to increase our profits over the next couple of years, therefore, is to add a clothing department along with an automotive supplies and repair shop. we should also plan to continue adding new departments and services, such as a restaurant and a garden shop, in subsequent years. being the only store in the area that offers such a range of services will give us a competitive advantage over other local stores.”

(21)“job security and salary should be based on employee performance, not on years of service. rewarding employees primarily for years of service discourages people from maintaining consistently high levels of productivity.”
Q
数学不难，除了一道题没看懂，瞎选了
What the amount in dollors to invest on a single interest rate of .02 annually for one year will be to equal $10,000 to invest on a interest rate of .04 annually for one year compounded semiannually?
A20,000
B20,150
...
其他答案不记得了，但是都比B要大，且好像小于等于25，000。题目大概是这样，数字肯定没记错。这题我不是太懂compounded semiannually在题目是什么意思,半年复利？我怎么算也想不出为什么结果等于或大于20，000。数学机经我没看完，不知道这题是否出现过。
其他题目我觉得都很简单，不少都是机经。所以题目我都没印象了，对不起。不过我相信，换了大家做这些题，肯定也都没问题。

第一篇讲科学家一直以为是体内一个什么东东控制动物和人的生物钟的rhythm,例如the fluctuation of the blood pressure.而且对动物的研究表明是这样。后来发现几个对rhythm有影响的gene并不存在于flies, rats和人的这个东东里。对rats做实验一天只喂一次食发现它们的某些rhythm改变，但那个东东控制的rhythm没变。所以科学家推断有其他的东东在体内影响生物的rhythm.
意思大概是这样，比较简单，有细节题，但是因为文章不长〔30-40lines)
所以挺简单。
