为什么不是 C ?答案d是怎么算出来的///搞不懂。
另外,“at a speed 4 times faster than he drove ”怎么理解?
如开车速度是V,那么飞机速度应是4V,还是5V ?
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.
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]
Could you believe it has same meaning between " .A...4 times greater than B.." and "..A...4 times as many as B...." , each expression meaning A=4B even though it is overtly different.
Hope we can get confirm from ETS. Langue is used by People.
