One of the latest trends(趋势) in American childcare is Chinese au pairs.Au Pair in Stamford，Conn，for example，has got increasing numbers of requests for Chinese au pairs from zero to around 4，000 since 2004.And that's true all across the country.

“I thought it would be very useful for him to learn Chinese at an early age，” Joseph Stocke，the managing director of a company，says of his 2-year-old son.“I would at least like to give him the chance to use the language in the future.” After only six months of being cared for by a 25-year-old woman from China，the boy can already understand basic Chinese daily expressions，his dad says.

Li Drake，a Chinese native raising two children in Minnesota with an American husband，had another reason for looking for an au pair from China：She didn't want her children to miss out on their roots.“Because I am Chinese，my husband and I wanted the children to keep exposed to(接触)the language and culture.” she says.

“Staying with a native speaker is better for children than simply sitting in a classroom，” says Suzanne Flynn，a professor in language education of Children.“But parents must understand that just one year with an au pair is unlikely to produce wonders.Complete mastery demands continued learning until the age of 10 or 12.”

The popularity of au pairs from China has been strengthened by the increasing numbers of American parents who want their children to learn Chinese.It is expected that American demand for au pairs will continue to rise in the next few years.

NEW YORK-Australian mining enterprise Clive Palmer on Tuesday unveiled(公布)blueprints for TitanicⅡ， a modern copy of the doomed ocean liner, although he didn't call the ship unsinkable any more.

The ship will largely recreate the design and decoration of the fabled original, with some modifications to keep it in line with current safety rules and shipbuilding practices, and the addition of some modern comforts such as air conditioning, Palmer said at a press conference in New York.

The three passenger classes, however, will be prevented from mingling(混杂), as in 1912, Palmer said.“I'm not too superstitious(迷信的).”Palmer said when asked whether recreating a ship best-known for sinking was tempting fate.

White Star Line, the operator of the original ship, had said the Titanic was designed to be unsinkable.About 1, 500 people died on Titanic's maiden voyage in 1912 from Southampton to New York after the ship collided with an iceberg in the North Atlantic.

Palmer, who created the company Blue Star Line last year, refused to make a similar boast.

“Anything will sink if you put a hole in it, ” Palmer said.“I think it would be very cavalier to say it.”

Unlike the original, TitanicⅡwill have more than enough space in its lifeboats for every person on board and will have additional escape staircases.Markku Kanerva, sales director at Deltamarin, the Finnish company designing the ship, said it would be the “safest cruise ship in the world”.

Palmer refused to answer questions about the project's cost.Although the Titanic was the world's largest ship in her time, she would be smaller than many of today's modern cruise ships.

“It's not about the money，” Palmer said.“I've got enough money for it.I think that's all that matters.”

Forbes estimated Palmer's net worth to be $795 million in 2012.He describes himself as a billionaire.

TitanicⅡwill be built by Chinese state-owned CSC Jinling Shipyard, which has already built four ore carriers for Palmer's mining business, he said.The contract to build TitanicⅡhas not yet been signed, Palmer said.

12.What can be inferred about TitanicⅡfrom the passage?

A.TitanicⅡwill have more space in its lifeboats than the Titanic.

B.TitanicⅡwill be the largest cruise ship in the world.

C.TitanicⅡwill allow different classes of passengers to mingle.

D.TitanicⅡwill be a real unsinkable cruise ship.

13.Which of the following statements is TRUE according to the passage?

A.1，500 people died on Titanic's maiden voyage in 1912.

B.The Titanic collided with an iceberg in the South Pacific.

C.The Titanic was equipped with air conditioning.

D.The Titanic was the world's largest ship at that time.

14.What's the author's purpose of writing the passage?

A.To tell us the story of the Titanic.

B.To tell us TitanicⅡwill cost a lot of money.

C.To tell us about the future Titanic.

D.To tell us a Chinese Shipyard will build TitanicⅡ.
