牛津高阶英汉双解词典第四版1600页在对"times"的解释中有下面的例子:
This book is three times as long as / three times longer than/ three times the length of that one.
中文翻译为:这本书是那本书篇幅的三倍(比那本书长两倍/篇幅为那本书的三倍).
可以认为上题应该是4V.[em09]
per #23, (1) is enough, no matter which card is laid on the table, it is diviseble by 2
(2) it depends. no rules is given regarding numbers which are not divisible by 3.
