A certain clock marks every hour by striking a number of times equal to the hour, 说明6点会敲6下
and the time required for a stroke is exactly equal to the time interval between strokes. 敲击所需要的时间等于敲击的时间间隔6-1=5
所以22秒内总共走了（5+6=11），所以每走一步花2秒。
敲钟和间隔时间一样，6点时敲6下隔5次，共11次，22秒，每下2秒
12点时，敲12下，隔11次，共23次，46秒
摆坏了，6点的时候应该摆六下花22秒，问12点的时候摆12下应该花几秒。

d项 antedate 先于，其他几项都在1500年之后了

公因数不能大于两数

with 1 and 2, we could count cupcake and donghut's price. but how many of donghut 0.4x+0.3y=6? no integer solution.

全家revenue in May is A, Lee in may earned 0.6A, in June is 0.6A*1.2=0.72A, in June， family total is 0.4A+0.72A. 0.71/1.12=64%. If the rest of the family's income was the same both months, understand it carefully,

总量为x，v1是x／5，v2是x／3，当总量为2／3 x时，h=（2／3 x） ／（x／5+x／3）

当x=0是，点分别为（0，0）（0，1／2）（0，5）（0，0）（0，5）

考时态

E 前半句同位语修饰 Incan highway，后半句ing伴随状语

弱弱地问一下....这一题主句的谓语动词是啥....找半天没找到

这题对我真是钻石级别的难题。。。。
