试题解析
记录容量
在购买数码相机的时候，一般会随机附送记忆体，这些记忆体的容量通常不大，对于300万像素的数码相机，随机记忆体一般为8-16MB，对于像素较大的数码相机，因为图片的体积大，所以随机记忆体的容量达到32MB。用户通常要另外买记忆体，否则仅凭随机记忆体可记录的图片和文件非常有限。存储卡的种类也分为很多种，例如CF卡、SD卡、索尼的记忆棒还有SM卡。就从储存的容量来说，看好的应该是SD卡和记忆棒，两者在储存量上的发展速度是惊人的，其中SD卡已经发展到4G的空间，适用于拍摄大分辨率图像的专业数码相机；而记忆棒的容量也达到了1G，也可以装载不少的图片。

Today ,as in every other day of the year ,more than 3000 U.S. adlescents will smoke their first cigarette on their way to becoming regular smokers as adults. During their lifetime,it can be expected that of these 3000 about 23 will be murdered,30 will die in traffic accidents, and nearly 750 will be killed by a smoking-related disease. The number of deaths attributed to cigarette smoking outweithts all other factors, whether voluntary or involuntary, as a cause of death. Since the late 1970s, when daily smoking among high school seniors reached 30 precent , smoking rates among youth have declined . While the decline is impressive ,several important issues must be raised. First, in the past several years,smoking rates among youth have declined very little. Second,in the late 1970s ,smoking among male high school seniors exceeded that among female by nearly 10 percent . The statistic is reversing.Third ,several recent studies have indicate high school dropouts have excessively high smoking rates, as much as 75 percent . Finally, thouth significant declines in adolescent smoking have occurred in the past decade,no definite reasons for the decline exist. Within this context,the Naional Cancer Instiute (NCI) began its current effort to determine the most effecive measures to reduce smoking levesl among youth.
