菜鸟问题---请教关于rate的使用方法和含义

三零年代

1. at an increasing rate of 是什么意思？
is rising at a rate of 2 percent annually  --- 以每年2%速度增加。
2. rate和rates怎么区分，我看到有些地方使用economic growth rates有时候使用economic growth rate?
这两个问题都是以下PREP的分析中看到的。请教各位

231.(T-4-Q3)

Currently 26 billion barrels a year, world consumption of oil is rising at a rate of 2 percent annually.

A.world consumption of oil is rising at a rate of

B.the world is consuming oil at an increasing rate of

C.the world’s oil is being consumed at the increasing rate of

D.the rise in the rate of the world’s oil consumption is(A)

E.oil is consumed by the world at an increasing rate of



题目释义：Currently 26 billion barrels a year, world consumption of oil is rising at …

考点：题目释义逻辑表达

1.同位语要对修饰对象有解释力，Currently 26 billion barrels a year应对其后的主语具有解释力。

2.is rising at a rate of 与 at an increasing rate of 是不同的逻辑概念

选项分析：A. Correct。

B. 同位语要有解释力，26biliion barrels a year无法解释the world；改变原意，at an increasing rate of 与is rising at a rate of是不同的概念。

C. 同位语要有解释力，26billion barrels才能解释oil，26billion barrels a year解释world consumption或者D的the rise。另eg. "50 degrees" would refer to a temperature."2 degrees per century" would refer to a rise/drop/change in temperature改变原意，同B。

D. “the rise in X is SPECIFIC NUMBER”是错误的表达，可以说the rise has been extremely rapid。

E. 同C的，另被动语态也显得没有必要的冗赘，直接world consumption of oil简洁。
