    1.      But science may have just proved them right – because beautiful women are more likely to have daughters than their plainer counterparts, according to a study.

As parents tend to pass on genes that determine looks, this could result in handsome men becoming rather thin on the ground.    2.     For example, Yasmin Le Bon is signed to the same modelling agency as daughter Amber, and Jerry Hall’s daughters Elizabeth and Georgia Jagger have both taken to the catwalk.  

Dr Satoshi Kanazawa, of the London School of Economics, analysed data from a survey of 17,000 babies born in Britain in March 1958 and tracked them throughout their lives.      3.     When they reached 45, they were asked about the gender of any children they had.

Those rated as attractive were equally likely to have a son or daughter as their first child – but the unattractive sorts were more likely to have a son.      4. 

Dr Kanazawa believes that parents tend to produce children who benefit from their own features.   5.     So it pays for attractive women to have daughters. But couples blessed with strength and aggression rather than looks are better off having boys, as these characteristics are of more use to males.

A. Women are becoming more beautiful over the generations because attractive women have

more children than plain ones.

B. Single girls have always complained that good-looking men are difficult to find.

C. Beauty is of more benefit to a woman than a man.

D. At the age of seven, their attractiveness was rated by their teachers.

E. Put another way, the beautiful women were more likely to have daughters.

F. And it may also explain why many models have daughters who follow in their fascinating footsteps.

G. Famously good-looking parents like Tom Cruise and Katie Holmes are more likely to have girls than uglier couples.

Federal regulators Wednesday approved a plan to create a nationwide emergency alert (警报) system using text messages delivered to cell phones.

Text messages have exploded in popularity in recent years, particularly among young people. The wireless industry’s trade association, CTIA, estimates (估计) more than 48 billions text messages are sent each month.

The plan comes from the Warning Alter and Response Network Act, a 2006 federal law that requires improvement to the nation’s emergency alter system. The act tasked the Federal Communications Commission (FCC) with coming up with new ways to alter the public about emergencies.

“The ability to deliver accurate and timely warning and alters through cell phone and other mobile services is an important next step in our efforts to help ensure that the American public has the information they need to take action to protect themselves and their families before, and during, disasters and other emergencies,” FCC Chairman Kevin Martin said following approval of the plan.

Participation in the alter system by carriers — telecommunication companies — is voluntary, but it has received solid support from the wireless industry.

The program would be optional for cell phone users. They also may not be charged for receiving alters.

There would be three types of messages, according to the rules.

The first would be a national alter from the president, likely involving  a terrorists attack or natural disaster. The second would involve “approaching threats,” which could include natural disasters like hurricanes or storms or even university shootings. The third would be reserved for child abduction (绑架)emergencies, or so-called Amber Alerts.

The service could be in place by 2010.

A. CTLA.   B. the Warning Alert and Response Network
