3月5日新SAT北美卷语法考试阅读第一篇中的第七题
[7] Mudskippers absorb oxygen mainly through their Rills while underwater. However, studies have shown that as much as 40 percent of their aquatic respiration can be skin based. On land, both modes are still important. When leaving the water, in preparation for less aqueous conditions, mudskippers fill their gill chambers with water from which they can later extract oxygen. Out of the water, when the amphibious fish are hopping along tidal mud flats or the edges of mangrove swamps, approximately 50 to 60 percent of respiration occurs through the skin, while respiration using their water-filled gills accounts for the remaining 40 to 50 percent.
7. Which choice most effectively combines the underlined sentences?
A) Mudskippers have been shown in studies to be able to do as much as 40 percent of their aquatic respiration through their skin, but they mainly do it through their gills underwater.
B) Although mudskippers absorb oxygen mainly through their gills while underwater, studies have shown that as much as 40 percent of their aquatic respiration can be skin based.
C) As much as 40 percent of aquatic respiration in mudskippers can be skin based, and studies have shown that they absorb oxygen mainly through their gills while underwater.
D) There are studies of mudskippers, which have shown that as much as 40 percent of their aquatic respiration can be skin based, and they absorb oxygen while underwater mainly through
答案：B
考点：考察的是合并句子
解析：这整篇文章一个生物话题类的文章。讲解的是一种可以在沼泽中生活的鱼——Mudskippers弹涂鱼有对环境有很强的适应能力，可以在各种残酷的环境中生存。这就是一个典型的考察句子合并。
解答这道题目需要通过考虑句子结构和句间逻辑来选择答案。文章中可以看出两句话间为转折关系。B答案 although体现了转折关系的并且表达最为简洁。A选项使用被动语态，不简洁;C选项and逻辑错误;D选项there be句型不简洁。
