LSAT－17－3－14 实在没信心了，大家给点建议吧

14.   Historically, monetary systems have developed only in population centers with marketplaces. Through the fourth century B.C. Mesopotamian cities engaged in trade, but had never had marketplaces. By that period, however, Greek cities all had marketplaces, or agorae. The Greek cities’ agorae were centrally located and goods were traded there either for money or for commodities.

If all of the statements in the passage are true, then which one of the following must also be true?

(A) In the fourth century B.C. Greek cities were the only population centers with monetary systems.

(B) The development of monetary systems has historically led to the development of marketplaces.

(C) In the fourth century B.C. the Greeks and the Mesopotamians traded with each other.

(D) After the fourth century B.C. Mesopotamian cities had marketplaces and monetary systems.（E）

(E) The Mesopotamian cities of the fourth century B.C. did not have monetary systems.

lsat 题中是不是有很多句子都是跟问题没有联系的？比方说这道

是不是从第一、二句话就可以推出E 了？

1。monetary systems------population centers with marketplaces.

2。Mesopotamian cities engaged in trade（这个trade在这里干什么，暗示什么？ 跟population center ,marketplace 有什么关系？）, but had never had marketplaces

so :  Mesopotamian cities no marketplaces,

后面又出了个greek city, 怎么知道greek city 与Mesopotamian cities 的关系啊？ 我当时作题就想成是两个city，现在看来是不是应该 Mesopotamian cities 属于greek city 的一种啊？

最后一句就更迷糊了，在说什么啊？The Greek cities’ agorae were centrally located and goods were traded there either for money or for commodities.

唉，这就是我的理解水平，大家有什么好的建议吗，对我这种打死都不开窍的人。现在lsat 我已经做了17套了，前面也分析了一些，可还是在60分钟，错12个以上的水平上，最糟糕的是错17个题，我是不是已经破最笨人的记录了呀，真是不想活了呀，我以前还是英语专业呢，简直是羞死了，现在都不敢告诉别人我的专业了。真想撬开脑门看看到底出什么毛病了！！是不是不该再继续做下去了，真没信心了！

我知道有人可能要劝我开始做OG, 可是我觉得我还是能力不够，能力够了的话，做什么都不在话下，我现在就是一门心思想把lsat攻下来，要不然做og也是一样错的很多，提高不大，关键还是能力啊！！ 各位xdjm们，给些建议吧，不会有比我更菜的了吧！！

1. the choice indeed can be made from the first two sentences;

2. the Meso- cities and Greek cities are two contrasting examples in support of the "Historically, monetary systems have developed only in population centers with marketplaces"

3. not every word in the argument dirctly relates to the question. some information simply serves the argument as an independent reasoning

4. I personally believe that your situation is normal. When i first started practice, i was no better than you. LSAT is frustrating to most of us, except a few real NNs. I'd say it is simply a matter of practice. So don't put doubt on your capability or something.

My suggestion is: concentrate on one type of questions at one time. Repeadly doing one type of questions before you move on to another type. You should have access to some guides on the approaches to each type of questions. Read them before you start practice, and reread them two or three times during and after the practice.

Thanks very much,chaseayang. Now I decided to follow your suggestions .

I need to focus on one type of questions, exactly right!

thank you again!
