When Dean Arnold got his first job, he was miserable (痛苦的), Each time he went to work, he coughed and he couldn’t breathe. Working in a bakery(面包房) when you are allergic to (对…过敏) flour can be painful.

    But Arnold stayed with the National Biscuit Company for ten years. He was a businessman and he helped them improve production. At last his health problems became too serious. He left and formed his own company.

    With his wife and mother, he founded Arnold Bakery. They tried new recipes (配方), changing the kind and amount of flour used. This enabled Arnold to work there without too much pain. The bread, made with unbleached flour (标准粉), was baked in a brick oven (烘炉).

    They began by baking two dozen loaves. The bread was sold door to door for fifteen cents a loaf. Winning customers to his unusual, old-fashioned bread took time. But Arnold, struggling against his allergy, built his bakery into one of the largest in the United States.

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 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 (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?

Children are our future, and it’s up to us to arm them with the tools to succeed. Sadly, today’s children are being armed with more dangerous tools like weapons （武器）, drugs and gangs. Once a relatively peaceful environment, many schoolyards of today are becoming unsafe for both students and teachers.

Home schools are available to give you choices. Home schooling provides top-quality education, flexibility, and freedom to create your own schedule. At Heritage Home School we believe the choice should be yours. Thanks in part to modern technology, home schooling information is becoming readily available across our nation. A recent study by the ITBS （Iowa Tests of Basic Skills） and TAP （Tests of Achievement and Proficiency） shows us that students of home schools do particularly well when compared with the nationwide average. In every subject at every grade level, students of home schooling scored obviously higher than those in public and private schools.

If you’re new to home schooling, you may be asking yourself, “Will home schools really work for my children?”

Fact: A nationwide study using a random（任意）selection of 1,516 families found students of home schooling to be scoring, on average, at or above the 80th percentile in all areas on standardized achievement test.

Note: The national average on standardized achievement tests is the 50th percentile. Collectively, the staff at Heritage Home School brings 65 years of experience in home schooling curriculum. We’ve placed students in the top 2 % of the nation in math and many are successfully moving on to college.

One study found that of the home schooled adults, 0% were unemployed, 0% were on welfare and 94% said home education prepared them to be independent persons. For more home schooling information, call us today toll free at（877）532-7665.

       Phys ed （physical education） is making a comeback as a part of the school core curriculum（核心课程）， but with a difference．While group sports are still part of the curriculum, the new way is to teach skills that are useful beyond gym class．Instead of learning how to climb a rope, children are taught to lift weights, balance their diets and build physical endurance（忍耐力）．In this way，kids are given the tools and skills and experiences so they can lead a physically active life the rest of their life．

       Considering that 15 percent of American children 6 to 18 are overweight, supporters say more money and thought must be put into phys ed curriculum．In many cases, that may mean not just replacing the old gym-class model with fitness programs but also starting up phys ed programs because school boards often "put P．E．on the chopping block（砧板）, cutting it entirely or decreasing its teachers or the days it is offered," says Alicia Moag-Stahlberg, the executive director of Action for Health Kids．The difference in phys ed programs is partly due to the lack of a national standard．"Physical education needs to be part of the core curriculum," she added．

       The wisdom of the new approach has some scientific support．Researchers at the University of Wisconsin have showed how effective the fit-for-life model of gym class can be．They observed how 50 overweight children lost more weight when they cycled and skied cross-country （越野）than when they played sports．The researchers also found that teaching sports like football resulted in less overall movement, partly because some reluctant students were able to sit on the bench．

       Another problem with simply teaching group sports in gym class is that only a small percentage of students continue playing them after graduating from high school．The new method teaches skills that translate to adulthood．

1.According to the passage, what is usually taught in the old gym class?

       A．Lift weights                                      B．Climb a rope    

       C．Cycle                                           D．Have a balanced diet

2.What does Alicia Moag-Stahlberg mean by saying “some school boards put P．E．on the chopping block”?

     A．Schools do not pay enough attention to P．E．．

     B．Schools welcome P．E．but do not have time for it．

     C．Schools put P．E．in the first place．

     D．Schools cut down other subjects’ time for P．E．．

3.Which is NOT the reason to carry out phys ed programs according to the passage?

     A．More teenagers are overweight．

     B．Traditional group sports teaching is not effective．

     C．Students need to learn some skills to help them lead a physically active life．

     D．Phys ed programs need less money to support．

4.How many problems are mentioned in the passage with simply teaching group sports?

     A．Two                B．Three             C．Four               D．One

5.What’s the difference between the come-back phys ed and the ordinary gym-class model？

     A．The Phys ed teaches group sports．

     B．The Phys ed provides more fitness programs．

     C．The Phys ed teaches tools and skills which could be used in the future life．

     D．The Phys ed has more support from the government．
