关于number和numbers的用法求问

fuchengxuan · 发表于 2012-7-12 22:24:45

什么时候用用their number,什么时候用their numbers?
之前看了一个帖子（http://forum.chasedream.com/archiver/GMAT_SC/thread-226606-1.html），仍然没理解到底
The gyrfalcon, an Arctic bird of prey, has survived a close brush with extinction, their numbers now fivefold what they were when the use of DDT was sharply restricted in the early 1970's.
这个句子中为什么用的是numbers而不是number.
我google了一下，关于their number 和their numbers的例句都有很多，百思不得其解。

楼主能再举一个用number的例子吗？
我感觉number和numbers没用明显的错误区别。只是用的时候应该有不同的理解吧~这应该不会成为一个绝对的考点吧。
比如您所举例句中的numbers可以指的是种群中鸟的数量，而种群有很多啊，所以数量也就不止一个，就用复数numbers。

their number:
1.The scientists at Loyola University in Chicago studied tennis prodigies to see whether playing another sport would increase or decrease their number of injuries.
2.The permits will be tradable, and their number will gradually decline.
their numbers:
1.Unless we know how many tigers are left in the wild, and whether their numbers are increasing or decreasing, we will not be able to conserve them.
2.Introducing these germs to the ants' new homes may start to keep their numbers in check.
请问有什么区别？

楼主发现了没有，你所举例子中的numbers都是用在了对生物数量的形容上，可以理解为同一物种不同种群的数量。
而number用单数的时候，所形容的名词都是可数的（这和manhattan上讲的是一样的，amount用来形容不可数名词），这时可以把number理解成“数目”，不管那个可数名词的数量有多少，其数目都是一个，用单数number即可。

只是自己的感觉，楼主可继续召唤大牛~~

时间久了，依稀记得曼哈顿说除了numbers of 这个固定搭配，其他情况不要用 numbers

那为什么这道题里用numbers呢...

试着说一下..感觉说出来也很乱..

numbers的出现情况，最适用的就是【一个种群它数量多少的变化】。就如同举得这个例子：
1.Unless we know how many tigers are left in the wild, and whether their numbers are increasing or decreasing, we will not be able to conserve them

也就是说，我们在描述的是The real number and change of a certain species, 它本身就有很多只（个）

但是一般情况下还是不要用numbers。

而这个为什么用number：The scientists at Loyola University in Chicago studied tennis prodigies to see whether playing another sport would increase or decrease their number of injuries.

是因为，这里的number更倾向于指示的是我在笔记本上记录下的这个数字。就是原来是4个受伤的，现在变成5个，但是我记录的就是一个很单纯的number，4 or 5....它其实并不同于上面提到的种群numbers变化的那个概念。。

是不是可以理解成，如果这个数字是具体的，能确定的，就用number，而对于不能精确确定的，只能是大概的用Numbers?
