2．Everyone would like to be a millionaire，a person with a lot of money，but can you imagine having over 30 million and only being 20 years old？Britney Spears from Kentwood，a small town in Louisiana，is only 20 years old．She is a world famous film star with not only 30 million but also a 2 million house in LA．At her young age，she can look after her family financially （經(jīng)濟(jì)上） all her life．This year is a big year for Britney．She is now on a 31-day tour of the US and every concert is a sell-out．That means she plays in front of a crowd of around 18，000 people every time．It's a tiring schedule but brings her a lot．When touring，she goes to bed around 1 a．m．a(chǎn)nd then has a lie-in until 1 p．m．the next day．Her philosophy （人生觀） is to take care of the body and relax but always make sure youwork hard and have fun．
Spears is not pleased with only touring and selling nearly 40million records so she decided to step into the movie business and try a bit of acting．She made an appearance in"Austin Power 3"this year and she is filming a teenage light play that will come out in March 2003．In this movie，she has a starring role．
For Britney，acting is another way to express herself and she is enthusiastic （熱心的） about it all．If her movies are successful，her money in the bank is sure to grow by another few million dollars but she does it for the love，not the money，as she herself tells the reporters．

3．When Jack was a small boy，he was once asked to give a speech about"A Big Challenge（挑戰(zhàn)） in My Life"．To talk before the whole class，he was（61）terribly （terrible） shy as soon as he thought of so many eyes （62）staring（stare） at him．He had no other（63）choice （choose），though．First Jack was to draft（打草稿） the speech，which was just a piece of cake for him because he was a good writer，But the hard part（64）lay （lie） in his oral presentation（展示），for it was not allowed to read from the paper．He had to give the speech （65）from his memory and in front of such a big audience（觀眾）!

4．Ask a teacher to name the most annoying invention of recent years and they will often mention the mobile phone．Disturbed by the problems they create，many head teachers have ordered that pupils should keep their phones switched off at school．Others have told pupils to leave them at home．
However，education researchers at The University of Nottingham believe it is time that phone bans were reassessed，because mobile phones can be a powerful learning aid，they say．Dr Elizabeth Hartnell-Young and her colleagues have reached this conclusion after studying the consequences of allowing pupils in five secondary schools to use either their own mobile phones or the new generation of‘smartphones'in lessons．
During the nine-month experiment，14-to-16-year-old pupils used the phones for a wide range of educational purposes，including creating short movies，setting homework reminders，recording a teacher reading a poem，and timing experiments with the phones'stopwatches．The smartphones，which could be connected to the Internet，also allowed pupils to access revision websites，log into the school email system，or transfer （轉(zhuǎn)存） electronic files between school and home．
The research involved 331pupils in schools in Cambridgeshire，West Berkshire and Nottingham．"At the start of the study，even pupils were often surprised at the thought that mobile phones could be used for learning，"Dr Hartnell-Young said．"After their hands-on experience，almost all pupils said they had enjoyed the project and felt more inspired．"
Some teachers found that pupils who lacked confidence gained most from the project．However，they recognized that greater use of mobile phones in schools could cause problems．

12．We can infer from the first paragraph thatD．
A．teachers are strongly against students owning mobile phones
B．mobile phones should be developed to meet students'needs
C．students are free to use their mobile phones at school
D．mobile phones are usually forbidden to be used at school
13．When the students first used mobile phones for learning，theyC．
A．a(chǎn)ll enjoyed the project very much
B．didn't know what they were used for
C．didn't fully realize the learning functions of mobile phones
D．were surprised that they were allowed to use mobile phones in schools
14．Who benefited most from the project？B
A．Older pupils．
B．Pupils who were not confident．
C．Younger pupils．
D．Pupils who were confident．
15．The purpose of the text is to tell us thatA．
A．mobile phones can actually help students learn
B．mobile phones begin to be widely used in schools
C．too much use of mobile phones in schools can cause problems
D．the mobile phone is considered the most annoying invention of recent years．
