1. component of sth
2.do without is a phrase, but i am comfused with the usage of making here, i think should be making does without ...
3.in greater detai than ever before should not be interrupted, my opinion, otherwise, you wont know the exact things being compared
4.A is right,the male and female blue-winged warbler is one of species of warbler, but the only difference is that it is blue-winged warbler, and the femal and male of this species are very difficult to tell apart.
B,the pronoun it here , do you think it can stand for what?
5.the subject of are here is ripples. if you choose c, what is the subject of it?

以下纯属个人意见:

2. making do 的意思是凑和着用,与did it without不同.

3.既然study in greater detail 说名study 已经开始了,不应在说possible to study. 另外in greater detail than ever before应尽量放在一起用否则导致比较对象不明.

4.应是B对.the male and female blue-winged warbler不属于warbler species 而B中

Blue-winged warblers 却是 species of warbler 种属关系清楚.

1.even as就相当于as,这个问题我也问过，后来在lsat上找到答案le
GMATEven as they never forgave) the Crusaders who overran their homeland, the Syians have never absolved the French for taking territory from them.

LSAT句子：Even as an individual fails to develop fully without constant interaction with an equal, a tradition of thought loses vitality and lacks the capacity for rigorous self-criticism without the probing presence of an authentic "other".
2.make do是固定词组，make do : to get along or manage with the means at hand,就是凑合着用的意思
3.study和后面的宾语分割太远
4.B is right,A中的most warbler species和the male and female blue-winged warbler不可比较。the pronoun it here stand for the infinitive "to tell..apart"
5.这位gg，你题目都没抄对阿
OG 205
The peaks of a mountain range, acting like rocks in a streambed, produce ripples in the air flowing over them; the resulting flow pattern, with (crests and troughs that remain stationary although the air that forms them is moving rapidly, are) known as "standing waves."
(A) crests and troughs that remain stationary although the air that forms them is moving rapidly, are
(B) crests and troughs that remain stationary although they are formed by rapidly moving air, are
(C) crests and troughs that remain stationary although the air that forms them is moving rapidly, is
(D) stationary crests and troughs although the air that forms them is moving rapidly, are
(E) stationary crests and troughs although they are formed by rapidly moving air, is
OG解释的意思是E把although引导的非独立状语从句放在了前置短语中（with crests..),正确的用法是只能出现在整个从句的谓语部分。具体的意思我也说不上来，只是觉得E中的although从句是在修饰crests and troughs,而C中的although从句好像是更独立一些，因为从句的主语是air,不是they(crests and troughs)。呵呵，估计我也没说明白，斑竹给解释一下吧：）

5 的关键我认为是 保留了remain 阿

tongxun

princess真是个细心人。5题你已经说的明白了。我再补充一下。
1）所有真题中although的用法，均符合OG 205。
2）在读题时，E给我的感觉在troughs 和although 间象少了点什么，怪怪的。具体也说不上来。大家试试。

5。 我是这样理解的：
OG的意思是说：although引导的非独立状语从句必须置于一个完整的从句中，用来修饰谓语，如C，although置于that从句中修饰remain stationary，而E中错将该从句用在了with短语中。

谢谢princess对even as 的解释，不过你举的lsat句子：

Even as an individual fails to develop fully without constant interaction with an equal, a tradition of thought loses vitality and lacks the capacity for rigorous self-criticism without the probing presence of an authentic "other".

我还是不太理解，可以具体解释一下么？

princess

这是一道逻辑题的题干
“就像一个人如果不和别人（equal)交流的话就无法充分发展一样，一种文化、思想如果不和对别的文化思想进行探索就会失去活力和自我批判的能力。”

大概就这个意思，even as 在这儿相当于just as，就像。。。一样

D,E 采用形容词修饰 crests and troughs 使 athough状语部分修饰不明确。
