4. The table above shows the cost of renting a piece of equipment from stores A and B. Each store charges a larger amount for the first hour and a smaller constant amount for each additional hour. For what number of hours will the two stores charge the same amount?

(D)Michael Phelps will not only win seven gold swimming medals, but claim many world records in addition

prefer to do A rather than do B （不能用to do B）

(D)created or profited

C的问题是it只能指代instrument，但这样就和原句即A句的意思不相符了。原句的意思是从没看过歌剧，而C的意思是从没看见过乐器。在SAT的选项中，凡是改变原句即A句的意思的选项一定是错误的。

本文作者在句子结构方面的驾驭能力，可以从以下几个例子看出一二。

把结论重复后，紧接着就是把自己的论据即刚才的例子再提一下，说明是从这几个例子中证明了刚才的论点的，大致可以写成From example A and B, we can draw such a conclusion。

比（ratio）：描述量与量之间的比较关系。常用的表示法如：2：3, <图>, 2 to 3。

We were talking about the Civil War and the abolition of slavery. I was well prepared, of course. I knew all about the Battle of Antietam and the Battle of Bentonville, I could find the battlefields on a map and tell you how many people had died. I raised my hand to give an answer and Mr. Blumgarden called on me. After I had answered, he asked me another question. But this was an unusual question. He asked me what I thoughtsoldiers on both sides thought about what they were fighting for. After that other people chimed in. And the class began to discuss the beliefs of both sides, the reason they went to war, and what might have happened if the other side had won. And I kept raising my hand, not to show how much I knew but, for once, because I was really interested.

第二段，讲“我”上社会课，要去询问老人所经历过的改变（we had an assignmentto interview an older person about the changes he or she had witnessed）。

分析：由题意，这是一个首项为2，公比为－2的等比序列。故在前50项中，25个项数为偶数的项为负，必小于100。剩下的25个项数为奇数的项可以看成首项为2公比为（－2）2＝4的等比序列，tn＝24n－1＜100

比如本题，问的是是否可以从失败中学到一些有益的东西，那么开头段落就应该围绕着“失败”、“成功”和“学习有益东西”来展开。

其实在写这套丛书之前，我就给自己定下一个目标，那就是希望最后同学们在看这套丛书的时候，就如同在课堂围坐在我的身边上课那样，听我娓娓道来。

平均数（average, arithmetic mean）：若干个数的平均数，是用这些数的和除以数的个数。

C为正确答案，三个名词完美平行（即creation, establishment和purchase），并且在名词后分别有个of接宾语，平行的三个部分都是采用了A of B的结构。

最后一段，语言又要回归庄重。

I do my homework better than Mary does.

表bite pressure，但从指代对象上讲，those只能指代一个复数名词，所以这个those的使用是存在问题的，应该改为that；另一个问题是，对于一个“名词's＋名词”的结构，其比较对象最好也是“名词's＋名词”的形式（或采用名词's的省略形式），而不应该采用A of B的结构。所以C选项的harder than those of German Shepherds应该改为German Shepherds'。

(C)either Gwen or that of Christine
