An annoying problem for humans, who like to boast (夸耀) about all the distant planets and moons we have explored, is that we've never taken a good look right under our noses．The inside of the earth is relatively close but how can we get there?

The deepest oil well enters a mere six miles into the crust (地壳)  (the center of the earth is about 4,000 miles deeper)．Russian scientists dug the deepest hole in Siberia," but bottomed out at about 7.5 miles below the surface．The Mohole project, a U.S．plan in the 1950s, called for drilling a hole 25 miles down to the boundary be??tween the hard rocks of the crust and the soft mantle (地幔)．Sadly the project involved govern??ment supporting.

It gets harder and harder to drill deep into the earth because rocks get softer and softer． Hard but easily broken at the surface, rocks become plastic at depth, and the pressure caused by the weight of the overlaying crust — about 52,800 pounds per square inch at a depth of ten miles, makes further drilling impossible.

What little we know about the inside of the earth (like the fact that there' s a crust, a mantle, and a core) comes from indirect evidence, such as the analysis of earthquakes.

So maybe it' s time for a thorough new method to explore the earth's inside．Scientist David Stevenson says we should forget about drilling holes．Instead, we should open a crack (裂缝)． 

Stevenson suggests digging a crack about a half mile long, a yard wide, and a half mile deep (not with a shovel) but with an explosion on the scale of a nuclear bomb．Next, he'd pour a few hundred thousand tons of molten (融化的) iron into the crack, along with a robot．The iron, thicker than the surrounding crust, would move downward at about 16 feet per second, carrying the robot with it and opening the crack deeper and deeper．The iron mass would drop for about a week and 2,000 miles to the outer edge of the earth core, the robot sending out data to the sur??face.

Stevenson compares his idea to space explo??ration．"We're going somewhere we haven't been before," he says．"In all possibility, there will be surprises."

This idea can probably be put in．the drawer marked with Isn't Going To Happen．The robot would have to survive temperatures that would melt pretty much anything．But Stevenson's idea may inspire a new look at an old problem．Great things can come from what seems like impossible ideas.

Going inside the earth is ________ than going into space.

A．more interesting B．more possible    C．easier            D．more challenging

How deep have we gone into the earth until now?

A．6 miles．         B．4,000 miles． C．7.5 miles．        D．25 miles.

Which of the following is TRUE about David Stevenson's idea?

A．It is an inspiring but not practical idea now．

B．It is a practical proposal that has come into use now.

C．It is a good proposal that will soon be put into practice.

D．It is a false theory that cannot be carried out at all.

What might be the most suitable title for the text?

A．An Annoying Problem for Humans

B．To the Center of the Earth

D．David Stevenson' s Proposal

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．

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．

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．

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

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

Why can coffee be used as a fuel?

A. It looks like wood or coal.          B. It contains some carbon content.

C. It is very cheap.                  D. It is much better than woodchips or nut shells.
