A和B 错选B 现在看起来觉得从局子的逻辑关系看A更合理；但在考试中做判断的时候，总觉得A中的they重复了，因为主语一直是Clovis points。不知道自己思维是不是陷进去了，请老师解答。

这种全部划线的改错好难做

我错选了A。A选项：spear points是Clovis points的同位语，但是they are named for the New Mexico site where they were first discovered in 1932. 这里的they指代不明，不知道是spear points还是Clovis points，排除。】这个理由成立嘛？ C：第一句有they，但是有疑问第一时间被解决了，是可以的，选之

这道题是全划线的，我选了D选项。整个句子划线这种题老做不好，老师帮忙解惑~ Even though Clovis points, spear points with longitudinal grooves chipped onto their faces, have been round all over north America ,they are named for the new Mexico site where whey were first discovered in 1932 A. Even though Clovis points , spear points with longitudinal grooves chipped onto their faces, have been found all over north America, they are named for the new Mexico site where they were first discovered in 1932.

Even though Clovis points, spear points with longitudinal grooves chipped onto their faces, have been found all over North America, they are named for the New Mexico site where they were first discovered in 1932. 题目全部划线内，把BDE杀掉，剩A,C.选A，正确答案C 个人读的意思是Clovis points found all，转折 named for the New Mexico。C中Named for the New Mexico site where they，这个they开始觉得没指明说谁，但是根据后面意思看出来是Clovis points。 (A)Even though Clovis points, spear points with longitudinal grooves chipped onto their faces, have been found all over North America, they are named for the New Mexico site where they were first discovered in 1932. (B) Although named for the New Mexico site where first discovered in 1932, Clovis points are spear points of longitudinal grooves chipped onto their faces and have been found all over North America. (C) Named for the New Mexico site where they have been first discovered in 1932, Clovis points, spear points of longitudinal grooves chipped onto the faces, have been found all over North America. (D) Spear points with longitudinal grooves that are chipped onto the faces, Clovis points, even though named for the New Mexico site where first discovered in 1932, but were found all over North America. (E) While Clovis points are spear points whose faces have longitudinal grooves chipped into them, they have been found all over North America, and named for the New Mexico site where they have been first discovered in 1932.

如何区分AC

OG这一题也是选A的。可是模考答案是C A为什么不好？ C中我把动词的时态读出来了。我觉得have been first discovered in 1932不好。就把它杀了。 听管老师的录音说A的主从句子调换了，我看不出这个错误。 但是管老师也说了C的这个时态确实有问题， 那要怎么比呢？？

Even though Clovis points, spear points with longitudinal grooves chipped onto their faces, have been found all over North America, thev are named for the New Mexico site where they were first discovered in 1932. (A) Even though Clovis points, spear points with longitudinal grooves chipped onto their faces, have been found all over North America, they are named for the New Mexico site where they were first discovered in 1932.

(E) While Clovis points are spear points whose faces have longitudinal grooves chipped into them, they have been found all over North America, and named for the New Mexico site where they have been first discovered in 1932. 答案有争议；OG ：A, 模考系统答案: C 自己选了A,因为感觉C中where they have been first discovered in 1932的时态不对； 请老师讲讲正确的答案和思路

读下来感觉好像强调墨西哥命名，就选了A
