实例题目：

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.

(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, pear 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.

选项分析：

(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.

【正确】由“even though”引导的从句“Clovis points……have been found all over North America”与其主句“they are named for the New Mexico site where they were first discovered in 1932”形成了合理的转折关系。“they were first discovered”使用一般过去时表意合理。

【大意】尽管Clovis points，一种有纵向血槽刻入表面的矛头已经在全北美被发现，它们以第一次被发现新墨西哥州遗迹被命名。

(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.

【错误】句子意思：“Although X，Y”结构中，让步成分X，应与其主句Y形成转折关系，然而本选项中“named for the New Mexico”与主句中的一部分“Clovis points are spear points”并不具有任何转折关系。

(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.

【错误】动词时态：现在完成时表达的含义是“过去发生，对现在仍有效果”，所以现在完成时的“have been first discovered”相比于(A)中一般过去时的“were first discovered”表意欠佳。

(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.

【错误】句子结构：“although(though)”和“but”不会同时用于一对转折关系中。

(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.

【错误1】动词时态：见(C)。

【错误2】句子意思： “Clovis points are spear points”和“they have been found all over North America”不具有转折关系，因此“Clovis points are spear points”不应用“while”引导。

解题思路：

一对转折关系中“although(though)”和“but”只用其一，立即排除(D)。

“be first discovered”用一般现在时比用现在完成时表意更为合理，排除(C)。

(B)、(E)中转折关系不合理，排除。因此选择(A)。
