1. They used them t cunt things like the days f the mnth, the amunt f fd and the number f animals they had. 人们利用它们来数数，像每个月的天数，食物的数量还有他们所拥有的牲畜的数目。amunt 用作名词，意为“数量；总额”，通常用于a (great / large) amunt f 短语中，表示“大量；许多”，其后通常接不可数名词。例如： 他赚了很多钱。 He made a large amunt f mney.
Language pints
注意the amunt f 和the number f 的区别：这两个短语都表示“……的数量”，其区别在于:前者与不可数名词连用，而后者与可数名词的复数形式连用。例如:降雨量影响农作物的生长。The amunt f rain affects the grwth f crps. 在过去的五十年里，老虎的数目锐减。The number f tigers has reduced sharply in the last fifty years.
2. They ften put the tkens n pieces f string s that they culd carry them arund easily.他们经常把代币悬在绳子上，这样他们可以轻松地四处携带它们。【句型】 s that 引导目的状语从句时，意为“以便；为了”， 从句中常使用can，culd，may 等情态动词。注意，s ... that ...引导的是结果状语从句，意为“如此……以至于……”，试比较：
为了赶上早班车，他今早很早就起床了。He gt up early this mrning s that he culd catch the early bus. 他今早起得太晚了，以至于错过了早班车。He gt up s late that he missed the early bus this mrning.
3. ... and this led t the Hindu-Arabic system (0-9).……然后这最终形成了阿拉伯数字系统。lead t 可表示：(1) (道路)等通往……。例如：条条道路通罗马。All rads lead t Rme. (2) 引起(结果等)；导致。常见搭配：lead t + n. / v.-ing。
那场大雨引起水灾。The heavy rain led t a fld.懒惰导致考试的失败。Laziness leads t failing the exam.注意以下搭配：lead sb t sme place 把某人带到某地lead sb t d sth 带领某人做某事
