OG的阅读跟着携隐她们做了第二遍, 今天结束.每组平均时间在35-40分钟, 没有刻意计时. 有的也用了50分钟. 平均错3-5题.
也看了OG解释, 大部分的都明白了(可是好象没什么作用,或许要拿来应用下再看, 我要开始做大全了)
问题是许多的错题居然还是第一遍就错了的, 看来还是有瓶颈没解决, 正在总结中)
今天先请教具体问题:
OG的第五篇, 关于胚胎形成的决定因素那篇
该题看了OG的解释也好象云里雾里,哪位DX给解释下?
25. It can be inferred from the passage that the morphogenetic determinants present in the early embryo are( 只能用排除法, 利用OG解释回文章对应, 没戏)
(A) located in the nucleus of the embryo cells
(B) evenly distributed unless the embryo is not developing normally
(C) inactive until the embryo cells become irreversibly committed to their final function
(D) identical to those that were already present in the unfertilized egg
(E) present in larger quantities than is necessary for the development of a single individual
括号当中那是我当时分析时的感觉
这道题确实应排除其他选项,对每个选项回原文对应。其实,如果能把这题做清楚,全文的基本框架也就差不多理解了。
这是个巨难题,那位大牛有好办法?
(D) identical to those that were already present in the unfertilized egg
unfertilized ,inactive
in the early embryo,active
C) inactive until the embryo cells become irreversibly committed to their final function
inactive untill fertilized
为什么c不对呢?
原文有:
" In the unfertilized egg, the substances are inactive and are not distributed homogeneously."
" In the unfertilized egg, the substances are inactive and are not distributed homogeneously."
可是irreversibly committed to their final function跟fertilized 不是指同一个时间,
时间上应该是unfertilized,然后fertilized,再后是at an early stage of its life,最后是irreversibly committed to their final function
