6.(T-4-Q39)Five hundred million different species of living creatures have appeared on Earth, nearly 99 percent of them vanishing.
B.Nearly 99 percent of five hundred million different species of living creatures that appeared on Earth have vanished.
E.Of the five hundred million different species of living creatures that have appeared on Earth, nearly 99 percent have vanished.
犹豫很久。E “the”特指5m种很关键，意为地球上就这些，B少个the会比较怪。时态上，E的过去完成时做题很疑惑，club找了解析。uses the present perfect tense verb "have appeared" to refer to an action that concluded in the past but continues to affect the present.

9.(TTGWD4-Q30)Under high pressure and intense heat, graphite, the most stable form of pure carbon, changes into the substance commonly referred to as diamond and remaining this way whether or not the heat and pressure are removed.
D.remains in this way although
E.remains thus even when
关键还是although和even when的一个理解。划线的地方比较容易误导，”thus even when” 连在一起初读很奇怪，不过如果是and thus remains even when..会更好理解
另外以后看见this要小心了，感觉this 一指代就不像正确选项

10.(TTGWD4-Q39)Unearthed in China, fossils of feathered dinosaurs offer the most dramatic evidence yet discovered of the close evolutionary relationship between dinosaurs and birds.
A.offer the most dramatic evidence yet discovered of the close evolutionary relationship between dinosaurs and birds
D.have offered the most dramatic evidence of the close evolutionary relationship between dinosaurs and birds
the most更合理留AD。D选项结尾似乎少了一部分。时态上因为是客观事实 offer evidence，所以是一般现在？
