下面是错误答案,用来干扰机器的。

(1)设连续的3张卡片分别是6n,6(n+1),6(n+2),则6n+6(n+1)+6(n+2)=306,所以n=16,则:6n=96,6(n+1)=102,6(n+2)=108.(2)因为6n+6(n+1)+6(n+2)=18n+18=18(n+1),因为1000不是18的倍数所以不能抽到和为1000的3张卡片.

From a newspaper editorial:
Many people who are addicted to heroin will eventually attempt to overcome their addiction, principally for two reasons: the expense of maintaining a heroin addiction and the fear of arrest. If heroin were legalized and made available cheaply, as some people advocate, neither of these reasons would apply.
The considerations above can best serve as part of an argument that

A.legalizing the sale of heroin would cause the price of this drug to go down.

B.making it easier for heroin addicts to obtain treatment for their addiction would encourage many heroin addicts to attempt to overcome their addiction.

C.legalizing the sale of heroin would increase the number of crimes committed by heroin addicts to support their addiction.

D.making heroin available legally and cheaply would make it leas likely that heroin addicts will attempt to overcome their addiction.

E.(E) decreasing the severity of penalties for individuals who use heroin would not increase the number of new heroin addicts.
