count

count, calculate, number, reckon

这组词都有“数”“计算”的意思,尤其是count和reckon在很多情况下可互换,它们之间的区别是:
1.count的含义是“数数目”; reckon则侧重“计算”。例如:
I counted the broken windows and found there were eight.
我数了数破损的窗户,共有八个。
We'll have to reckon the cost of it.
我们得计算它的成本。
2.count和reckon都有“认为”之义,但reckon则更侧重于“推定”“公认”,指对事件全面权衡。例如:
Because our family is happy and healthy, we reckon ourselves fortunate.我们很幸运,因为我们的家庭是一个健康、幸福的家庭。
3.calculate作“计算,核算”解时,指通过较复杂的过程,如:算术上的加减乘除或精密计算等。例如:
Can you calculate how much a trip to the Great Wall will cost?你能计算去长城旅游一次要多少钱吗?
4.count和reckon多用于口语或日常生活; calculate多用于自然科学、生产部门或需要专门计算的场合。例如:
Astronomers can calculate when there will be eclipses of the sun and the moon.天文学家能算出什么时候有日食、月食。
5.count既可用作动词,也可用作名词；而calculate和reckon只能用作动词。
6.number侧重“编号”。

count up to, add up to, amount to, come to, run into

这五个短语动词都是“总计”的意思,其差别很细微：
1.从构成上说, add up to和count up to是动副介型短语; 而amount to, come to和run into是动介型短语。
2.从主语上说, add up to和come to相同,均多为钱、账单、数目等; amount to和run into的主语多为loss, cost, expense, debt, sum等名词; 而count up to的主语则仅限It。例如:
Our hotel bill added up to〔amounted to,came to〕 300 dollars.我们的旅馆费共计300美元。
His debts amounted to〔ran into〕 over 3000 dollars.他的债务已高达3000多美元。
It counts up to 300 dollars.共计300美元。
3.从宾语上说, add up to, amount to, come to后一般接数字; 而count up to和run into后除可接数字外,还可接名词。例如:
It counts up to a considerable sum.合计起来数目相当可观。
Losses run into six figures.损失高达6位数。
4.从使用场合上说, come to最通俗, count up to不常用。
