问题:

Better think twice before choosing a password for e-mail, online bank or shopping. Simple passwords are easy to be stolen.

A password is like a key to your home. If someone steals it, he’ll get chances to steal something else. We use passwords everywhere in our life. We are so used to passwords that we don’t pay any attention to them until we lose or forget one.

A study of 28,000 passwords recently stolen from a popular website showed that people often do the easy thing. It found that 16 percent took a first name as a password. Another 14 percent used the easiest keyboard combinations such as “12345678” or QWERTY. Five percent of the stolen passwords were names of television shows or stars popular with young people. Three percent of the passwords expressed feelings like “I don’t care,” “Whatever,” “I love you,” or their opposite, “I hate you.”

Robert Graham, who did the study, advises people to choose a password that is longer than eight characters with one capital letter(大写字母) and one symbol.

Of course, safe passwords don’t mean those hard to remember. Forgetting your password is sometimes a big headache for you. Maybe, the perfect password is easy for you and hard for others.

研究人员发现美国人口的老龄化或将有助于减缓全球变暖。一名人口统计学家使用了一种新的计算机模型来研究年龄与二氧化碳排放量之间的关系,显示美国人在退休之后对全球变暖的“贡献”就会减少。
如果以下各项为真,最能支持研究人员观点的是:

A.研究发现随着年龄增长,美国人二氧化碳的排放量逐渐增大,这种趋势会在65岁前后达到顶峰,然后骤然回落
B.研究报告认为,与美国有着类似的老龄化人口结构和消费模式的国家也许会发现它们的二氧化碳排放量将减少
C.有研究表明,65岁及以上的美国人捐献给关注全球变暖的绿色环保基金的慈善款金额高于其他年龄段的美国人
D.研究显示,美国二战后“婴儿潮”一代在退休之后的二氧化碳排放量在2030年后将逐渐减少,减幅十分显著
