50．According to the US' Office for National Statistic（统计），women reaching the end of their childbearing years had about 1.9 children each in 2004，compared with 3.1 for those women in 1976．Numbers from the UK's Office for National Statistics show a similar matter across the Atlantic：the percentage of one-child families in Britain had risen from 18 percent in 1972 to 26 percent in 2007．
But even though only children are becoming increasingly common，the stereotype（偏见） that they're selfish，spoilt（宠坏的） and short of social skills holds strong．Even parents of only children are made to feel guilty about having only one child．Worried that they're being selfish and endangering their child's future，they rush to online trying to get advice．Soon，however，they ask themselves：is this social stereotype really reasonable？
"There have been hundreds and hundreds of research studies that show that only children are no different from their mates，" Susan Newman，a social psychologist（心理学家） at Rutgers University in the US，told ABC News．
A perfect example is Natalie Portman． "I had the only attention of my parents．And you know what？If I had had brothers or sisters I would have never become an actress，" she told Naanoo，an online magazine． "My mother has been with me to every audition（试听） and every acting class．With more children that would have never been possible．They would have been jealous（妒嫉） of me．"
This raises another question：why are only children still get such suspicion（质疑）？
"There is a long-lasting belief that's been around probably since humans first existed that to have just one child is somehow dangerous，both for you and for the continuation of your race，" Toni Falbo，a professor of educational psychology at Texas University's Population Research Center，told The Guardian． "In the past a lot of children died．You'd have had to be crazy to only have one．"
Times，of course，have changed and baby's death has largely disappeared．So what do only children themselves say？Kayley Kravitz，a blogger for The Huffington Post，grew up as an only child and highly praises the experience． "Being an only child taught me the most valuable skill of all：the ability to be alone，" she said．
（1）What does the writer probably think of only children？
A．They are big problems．
B．They usually have more free time．
C．They are almost the same as others．
D．They can learn more social skills from their parents．
（2）What does the word "guilty " in paragraph 2 mean probably？

C．Disappointed．
D．Proud．
（3）What can we infer from the passage？
A．There were more only children in 2007．
B．Only children have more ability to be alone．
C．People usually have stereotypes on only children．
D．Modern medical technology makes only children more acceptable．
（4）The writer mainly wants to tell us that．
A．only children are social problems we should face directly
B．the parents were worried because of the stereotype
C．only children have more problems than others
D．there are more and more only children组卷：3引用：1难度：0.2 -
51．Spam （垃圾邮件） mail is a fact of Internet life．Some of it carries bad things，but the main problem with spam is that it is unpleasant because it fills your mail box with pointless messages．
Most email programs have built-in filters （过滤器） that will discover unwanted messages and put them into a junk folder （垃圾文件夹）．You can make the filter learn what you consider to be spam or block certain senders．
Avoid letting your email address appear on websites-spammers search the Internet for email addresses．Be careful who you give your email address to，and if you need to send out several copies of an email，use blind copy instead to cover the other people's addresses．
Delete （删除） spam emails without opening them．Signs of possible spam are bad spelling in email headers，strange sender addresses，or emails sent at unusual hours．If you do open a spam mail，never reply to it or click on any pictures it may have．
If you receive an unexpected email pretending （伪装） to come from your bank，credit card company or other suppliers，be very careful．If the email asks you to reply，don't do it!Instead，call up these places or visit their websites．
Consider setting up a second email address and keep one address for your personal use and another for your online communication．

A．It's everywhere．
