每日翻译练习[七十]

Prolonged and unseasonable frosts produce frost rings in deciduous trees, which grow in moderate climates. Frost rings do not appear in any of the fossilized deciduous trees that have been found in Antarctica. Hence, it is unlikely that such frosts occurred in Antarctica at the time the fossilized trees lived.

Which of the following is an assumption on which the argument depends?

 

  • There are fossilized no deciduous trees from Antarctica that bear frost rings.
  • Deciduous trees are more likely to bear frost rings than are other tree varieties.
  • The process of fossilization does not completely obscure frost rings in deciduous trees.
  • Present-day deciduous trees are more sensitive to changes in temperature than were the deciduous trees of ancient Antarctica.
  • Prolonged and unseasonable frosts that might have occurred in Antarctica when the now fossilized trees were still living did not always produce frost rings in deciduous trees.

答案:(C)

 

读题:持续的并且不合季节的霜冻会在落叶树上产生霜环,落叶树一般都生长在温和的气   候。在南极洲发现的落叶树化石上都没有霜环,因此,在当时有落叶树生长的时候,南极洲有这种霜冻的可能性不大。

 

问题:下面哪一个是上面的论述所基于的假设?

 

A. 南极洲有些落叶树化石上有霜环。

B. 落叶树比其它树种更易于有霜环。

C. 形成化石的过程中并不会完全使落叶树上的霜环消失。

D. 如今的落叶树比南极洲的落叶树对气温的变化更敏感。

E. 当如今的化石树仍然生长在南极洲时,南极洲上可能也有持续的反季节霜冻。但当时霜冻并不总是在落叶树上产生霜环。
