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 (地殼) (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 between the hard rocks of the crust and the soft mantle (地幔). Sadly the project involved government 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 (裂縫).
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 (熔化的) 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 surface.
Stevenson compares his idea to space exploration. "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
C. The Mohole Project
D. David Stevenson's Proposal

Dear Jack,
I’m middle school student. I’m writing to tell you my problem with my mother. She is a doctor, whom works very hard. She is strict in me, but she is too busy with her work that she found little time to talk to me. I love her
and I do well in my studies, but I still feel a little of afraid of her because she loses her temper easy. I don’t know how to communicate with her. Maybe that’s why we have seldom sat down and exchanged our feeling and thoughts. I hope we can know more about each other and understand each other well. I do hope we’ll be closer. What can I do?
Looking forward to your reply.
Best wishes!
Your sincerely,
Tom

Everyone needs friends. We all like to feel close to someone. It is nice to have a friend to talk, laugh and do things with. Sure, there are times when we need to be alone. We don’t always want people around. But we would feel lonely if we never had a friend.
No two people are the same. Sometimes friends don’t get along well. That doesn’t mean they no longer like each other. Most of the time they will go on being friends. Sometimes friends move away. Then we feel very sad. We miss them very much. But we can call them and write to them. Maybe we wound never see them again. And we can make new friends. It is surprising to find out how much we like new people when we get to know them. Families sometimes name their children after a close friend. Many places are named after men and women, if they are friendly to people in a town. Some libraries are named in this way. So are some schools. We think of these people when we go to these places.
There is more good news for people, if they have friends. These people live longer than those people who don’t have friends. Why? It could be that they are happier. Being happy helps you stay well. Or it could be just knowing that someone cares. If someone cares about you, you take better care of yourself.

科目:高中英語 來源:2011年浙江普通高等學(xué)校招生全國統(tǒng)一考試英語試卷 題型:閱讀理解
One evening in February 2007 . a student named Paula Ceely brought her car to a stop on a remote in Wales . She got out to open a metal gate that blocked her path . That's when she heard the whistle sounded by the driver of a train.Her Renault Clio parked across a railway line. Second later,she watched the train drag her car almost a kilometre down the railway tracks.
Ceely's near miss made the news because she blamed it on her GPS device(導(dǎo)航儀).She had never driven the route before .It was dark and raining heavily . Ceely was relying on her GPS. But it made no mention of the crossing ."I put my complete trust in the device and it led me right into the path of a speeding train ,"she told the BBC.
W ho is to blame here ? Rick Stevenson ,who tells Ceely's story in his book When Machines Fail US, finger at the limitations of technology. We put our faith in digital devices, he says,
but our digital helpers are too often not up to the job. They are filled with small problems. And it’s not just GPS devices: Stevenson takes us on a tour of digital disasters involving everything from mobile phones to wireless key boards.
The problem with his argument in the book is that it’s not clear why he only focuses digital technology,while there may be a number of other possible causes. A map-maker might have left the crossing off a paper map. Maybe we should blame Ceely for not paying attention. perhaps the railway authorities are at fault for poor signaling system. Or maybe someone has studied the relative dangers and worked out that there really is something specific wrong with the CPS equipment. But Stevenson doesn’t say.
It’s a problem that runs through the book. In a section on cars, Stevenson gives an accout of the advanced techniques that criminals use to defeat computer-based locking systems for cars. He offers two independent sets of figures on car theft; both show a small rise in some parts of the country. He says that once once again not all new locks have proved reliable. Perhaps, but maybe it’s also due to the shortage of policemen on the streets. Or changing social circumstances. Or some combination of these factors .
The game between humans and their smart devices is complex. It is shaped by economics and psychology and the cultures we live in. Somewhere in the mix of those forces there may be way a wiser use of technology.
If there is such a way, it should involve more than just an awareness of the shortcomings of our machines. After all, we have lived with them for thousands of years. They have probably been fooling us for just as long .
