终于确定,重复阅读以前的文章是有用处的。
今天上午重读了两篇OG上的文章,其中把那个《embryo》的逻辑图画出来之后,忽然发现,所有的题目围绕的不是所谓的“假说”或者“理论”的内容(我以前一直这样认为),而是所提到的各个概念的逻辑关系!或者是因果,或者是前提,总之是各种逻辑关系。
比如说:
4. According to the passage, when biologists believed that the cells in the early embryo were undetermined, they made which of the following mistakes?
这个问题是首段中提到的两个先决条件之一。
而这两个先决条件,同时在第8题也出现了。
8. The passage suggests that which of the following plays arole in determining whether an embryo separated intotwo parts will two parts will develop as two normalembryos?Ⅰ.The stage in the embryo's life at which the separationoccursⅡ. The instrument with which the separations isaccomplishedⅢ. The plane in which the cut is made that separatesthe embryo
第6题最缺德了,不过我觉得也是体现得最明显的。
6. It can be inferred from the passage that which of thefollowing is dependent on the fertilization of an egg?
这道题是这样的,从第2段中找到substances,然后到第4段中,告诉你这个substances就是
maternal messenger RNA's --products of certain of the maternalgenes. He and other biologists studying a wide varietyof organisms have found that these particular RNA's direct, in large part, the synthesis of histones, a classof proteins that bind to DNA.
所以这道题就选B,Sythesis of proteins called histones 。
不知道我的体会对不对?这点体会对阅读水平提高能有多大点的作用呢?
