A car that runs on coffee is unveiled（shown to the public for the first time）today but at between 25 and 50 times the cost of running a car on petrol, the invention won’t please any motor industry accountants．
Nicknamed the Car-puccino, it has been created using a 1988 Volkswagen Scirocco bought for £400 and it was chosen because it looked like the time-traveling DeLorean in the movie Back To The Future．The car will be driven the 210 miles between Manchester and London powered only by roasted coffee granules （颗粒）．It has been built by a team from the BBC1 science programme Bang Goes The Theory and will go on display at the Big Bang science fair in Manchester to show how fuels other than traditional petrol can power vehicles．
The team calculates the Car-puccino will do three miles per kilo of ground coffee （咖啡粉） — about 56 cups of espressos （浓咖啡） per mile．The journey will use about 70 kilos of ground coffee which, at supermarket prices of between £13 and £26 a kilo depending on brand and quality, will cost between £910 and £1,820, or between 25 and 50 times the £36 cost of petrol for the journey．In total, the trip will cost 11,760 espressos, and the team will have to take ‘coffee breaks’ roughly every 30 to 45 miles to pour in more granules．They will also have to stop about every 60 miles to clean out the ‘coffee filters’ to rid them of the soot and tar which is also generated by the process．So despite a top speed of 60mph, the many stops mean the going will be slow, with the journey taking around ten hours．
Sadly, the inventors will still have to pay duty on their coffee fuel---even though tax collectors at Her Majesty’s Revenue and Custom haven’t yet worked out how much．
Nick Watson, producer of Bang Goes The Theory, said, “Coffee, like wood or coal, has some carbon content so you can use it as a fuel．The coffee needs to be very dry and in granules to allow the air to move through the pile of coffee as it burns．The brand doesn’t matter．” He said the same technology could be used to power a car on other unusual fuels, such as woodchips or nut shells, construction or agricultural waste．
49．Which is the right way to choose the coffee used as fuels to run the Car-puccino?
A．It should be very dry．                B．The stronger, the better．
C．The smaller the granules are, the better．  D．It should be of a certain brand．
50．What can be inferred from the passage?
A．All kinds of materials can be used as fuels．
B．The Car-puccino will be put into the market soon．
C．Nick Watson is the designer of the Car-puccino
D．Much remains to be improved for the Car-puccino．
51．The Car-puccino has its disadvantages EXCEPT that ________．
A．it makes a lot of noise           
B．it runs at a very high cost
C．it has to stop to be refueled very often．       
D．it’s not good enough for long-distance journey
52．How much ground coffee will be used to cover a distance of 126 miles in this car?
A．About 70 kilos    B．About 42 kilos．  C．About 32 kilos    D．About 30 kilos

The rise of the so-called “boomerang generation” is revealed in official figures showing that almost one in five graduates in their late 20s now live with their parents.
By contrast, only one in eight university graduates had failed to fly the nest by the same age 20 years ago. It also found that grown-up sons are twice as likely as their sisters to still be living with their parents in their late 20s. With nearly a quarter of men approaching 30 still living at home, the findings are bound to lead to claims of a “generation of mummy’s boys”.
Young professionals in their late 20s or early 30s have been nicknamed the “boomerang generation” because of the trend toward returning to the family home having initially left to study. Recent research has suggested that young people in Britain are twice as likely to choose to live with their parents in their late 20s than their counterparts elsewhere in Europe.
Rising property prices, mounting student debts and the effects of recession on the job market have forced a wave of young people to move back into the family home at an age when they would normally be moving out. But commentators warned that the phenomenon may have more to do with young people facing “dire” prospects than simply a desire to save money.
While the proportion of those of university or college age moving out from the family home has continued to rise in the last 20 years, among those in their mid and late 20s the trend has been reversed. Overall 1.7 million people aged from 22 to 29 now share a roof with their parents, including more than 760,000 in their late 20s. In 1988, 22.7 per cent of men aged 25 to 29 were still living with their parents but last year the proportion was 24.5 per cent.
【小题1】 What is the main idea of the passage?

A．Male children seem to more independent than females.

B．Eighty percent of university graduates were able to live independently two decades ago.

C．The grown-up children choose to live with their parents only to save money.

D．More and more children are moving out at university age.
