在英语学习中,一些简单的数学等式,例如“2+3=5”,我们应该怎样正确用英语表达这个数学等式呢? 等号“=”的英语表达在数学等式里,“=”是必要存在的,不然就不能称之为等式了。那么,在英语里我们可以用“is/are”、“equal”或“is/are equal to”来代表等号“=”。 加“+”、减“-”、乘“×”、除“÷”的英语表达
例子:3+1=4 英语表达: ① Three and one is four. ② Three plus one equals four. ③ Three added to one are four. ④ If we add three to one,we get four.
例子:10-2=8 英语表达: ① Ten minus two is eight. ② Two taken from ten equals eight.
例子:8×7=56 英语表达: ① Eight times seven are fifty-six. ② Eight multiplied by seven is fifty-six.
例子:20÷5=4 英语表达: Twenty divided by five are equal to four. 用“How much is”来提问数学算式在英文里,“How much is”不仅可以用来表达“多少钱?”的意思,在算式提问中还可以用来表达“等于多少?”的意思。 例子: ① “7+4=?”可表示为:“How much is seven plus four?” ② “12-6=?”可表示为“How much is twelve minus six?” ③ “3×2=?”可表示为“How much is three times two?” ④ “15÷5=?”可表示为“How much is fifteen divided by five?” |
