Question

我们教室面积是他们的两倍大,英语有疑问,
Our classroom is twice as big as theirs.
Our classroom is bigger than theirs.
Our classroom is twice the size of theirs.
我们老师说三处都用twice
,但参考书有一处是once
希望可以解答,这里到底是twice还是once
Our classroom is once bigger than theirs

Answer 1

这和汉语里差不多……
Our classroom is twice as big as theirs 这句话是说我们的教室是他们两个教室的大（他们*2=我们）
Our classroom is !once !bigger than theirs 而这句话是说我们的教室比他们还大一倍（我们大于他们 且他们+他们=我们）
第三句应该和第一句一样的
关键在一个as……as和一个bigger than上
一个是和……一样 强调一样 另一个强调比……大
也就是：一个是等式 一个是不等式~~~
