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 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 (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
C.The Mohole Project
D.David Stevenson' s Proposal

When I was in middle school, I was one of the smaller players on the basketball team. In our first game of the season, we were 31 to face a good team, all of whom were tall guys. Naturally, at my 32 , it would have been easy to be 33 by our competitors.
On game day, my basketball coach called me over to him. He was a strong and tough coach, and in his 34 rough manner said, “Joel, you’re not that 35 , but let me tell you that size doesn’t matter. Don’t be afraid. What 36 is right down in here.” He pointed his finger at his 37 as he continued, “Joel, you’ve got a big heart, and you’re to 38 it this year.”
When I heard the coach’s 39 , I stood taller than usual! I thought to myself: The coach believes in me! My confidence 40 and I played better that year than I’d ever done before.
It’s 41 what we can achieve when we know somebody really believes in us. That coach took a little time to make a big 42 . He took time to make me confident in myself. If we’re going to 43 the best in people, we need to sow seeds of 44 .
As the saying goes, “Love looks for a way of being constructive.” 45 , love looks for ways to help improve somebody else’s life.
When people are 46 us, they should leave better off than they were before. People should feel 47 and inspired after spending any time with you and me 48 feeling discouraged or defeated.
Remember, there’s 49 greater investment(投資)in life than in being a people builder. Relationships 50 much more to us than our achievements.

My parents were in a huge argument, and 1 was really upset about it. I didn't know who I should talk with about how I was feeling. So I asked Mom to allow me to stay the night at my best friend's house. Though I knew I wouldn't tell her about my parents’ situation, I was looking forward to gelling out of the house. I was in the middle of packing up my things when suddenly the power went out in the neighborhood. Mom came to tell me that I should stay with my grandpa until the power came back on.
I was really disappointed because I felt that we did not have much to talk about. But I knew he would be frightened alone in the dark. I went to his room and told him that I'd stay with him until the power was restored. He was quite happy and said, "Great opportunity."
"What is?" I asked.
"To talk, you and I" he said. "To hold a private little meeting about what we’re going to do with your mom and dad, and what we're going to do with ourselves now that we're in the situation we are in."
"But we can't do anything about it. Grandpa," I said, surprised that here was someone with whom I could share my feelings and someone who was in the same "boat" as I was.
And that's how the most unbelievable friendship between my grandfather and me started. Sitting Acre in the dark, we talked about our feelings and fears of life — from how fast things change, to how they sometimes don't change fast enough. That night, because the power went out, I found a new friend, with whom I could safely talk about all my fears and pains, whatever they may be — suddenly, the lights all came hack on. "Well," he said, "I guess that means you'll want to go now. I really like our talk. I hope the power will go out every few nights!"
