[填空题]One of the founding fathers of the Internet has predicted the end of traditional television. Vint Cerf, who helped to build the Internet while working as a researcher in America, said that television was approaching its" iPod moment". In the same way that people now download their favorite music onto their iPod, he said that viewers would soon be downloading most of favorite programs onto their computers.
"85 percent of ail videos we watch is pre-recorded, so you can set your system to download it all the time," said Mr. Cerf, who is now the vice-president of the Google, the world’s largest search engine. "You’re still going to need live television for certain things-like news, sporting events and emergencies-but increasingly it is going to be almost like the iPod, where you download content to look at later."

The first navigational lights in the New World were probably lanterns hung at harbor entrances.The first lighthouse was put up by the Massachusetts Bay Colony in 1716 on Little Brewster Island at the entrance to Boston Harbor, Paid for and maintained by“light dues”levied（征 收）on ships,the original beacon was blown up in 1776.Until then there were only a dozen or so true lighthouses in the colonies.Little over a century later,there were 700 lighthouses.
The first eight lighthouses erected on the West Coast in the 1850s featured the same basic New England design:a Cape Cod dwelling with the tower rising from the center or standing close by .In New England and elsewhere,though,lighthouses reflected a variety of architectural styles.
Since most stations in the Northeast were set up on rocky eminences（高处）,enormous towers were not the rule .Some were made of stone and brick,others of wood or metal.Some stood on pilings or stilts;some were fastened to rock with iron rods.Farther south,from Maryland through the Florida Keys,the coast was low and sandy.It was often necessary to build tall towers theremassive structures like the majestic lighthouse in Cape Hatteras,North Carolina,which was lit in 1870.190 feet high,it is the tallest brick lighthouse in the country.
Not withstanding differences in construction appearance,most lighthouses in America shared several features:a light,living quarters,and sometimes a bell(or,later,a foghorn).They also had something else in common:a keeper and usually the keeper's family.The keeper's essential task was trimming the lantern wick（灯芯）in order to maintain a steady,bright flame. The earliest keepers came from every walk of life, they were seamen,farmers,mechanics,rough mill hands and appointments were often handed out by local customs commissioners as political plums.
After the administration of lighthouse was taken over in 1852 by the United States Lighthouse Board,and agency of the Treasury Department,the keeper corps gradually became highly professional.
Why does the author mention the Massachusetts Bay Colony?
A.It was the headquarters of the United States Lighthouse Board.
B.Many of the tallest lighthouses were built there.
C.The first lantern wicks were developed there.
D.The first lighthouse in North America was built there.

Work hard and get ahead. That’s what every American learns growing up, but for millions of them, it’s getting harder to tell the difference between working hard and being a workaholic. "The line happens when you come home one day and your husband isn’t there, and you didn’t realize he left you a week ago," Stephen Viscusi said. Viscusi is CEO of the Viscusi Group.
The actual reasons for becoming a workaholic are quite varied. It might involve a need in someone to always stay a step ahead of their co-workers or anyone else they perceive as a competitive threat. It could be a desire to never leave the office at night without tying up any loose ends such as returning an email, writing a memo or getting a package out. It might be a single-minded commitment to being successful, gaining promotion after promotion, no matter what the cost.
