count backwards

I could count backwards in this time.

这么久我都可以倒数回去了。

I want you to snap your fingers exactly 50 times, or count backwards from 100 by seven, like this: 100, 93... Go!

我想你们打50次的响指，或者从100开始，每隔七位数倒数，100，93……开始！

Cannot count lines backwards! ( Internal error) { 0}, { 1}

无法向后计算行数！（内部错误）{0}、{1}

Aren't you usually the second count backwards?

平时都不是考倒数第二的吗？

The N content per unit leaf area was the highest in the second leaf count backwards, and that of decrepit leaf was about the 1/ 3 of the normal leaf.

单位叶面积含N率以倒数第2展开叶最高，衰老叶片只有正常叶片的1/3左右。

Aren't you usually the second count backwards? What to do with so bad result?

补考。我的成绩一直很稳定。因为平时考倒数第一的人生病了。

If you knew in advance, you could have, actually, your car's mileage counter to count backwards from the point where the car will die and start walking.

如果你事先知道，你可以倒着走，用里程表计算从起点到终点的路程。
