It’s certain that the following tale is a nice example that can teach us a good lesson. One day, a young man 16 begged from door to door along the street. 17 an old wallet in hand, he was asking for a few coins to buy something to eat. He kept complaining about his bad 18 and kept wondering why those who had so much money were never 19 and were always desiring more.
“As for me, if I had only enough to eat and to wear, I would not want anything more."
Just at that moment Goddess Fortune 20 the beggar among the crowd and approached him, greeting, “Hi, young man, I have wished to 21 you for a long time. If you open your wallet, I will pour my gold into it. But keep in mind that I will do that only on this 22 : All that falls into the wallet will be pure gold belonging to you; but every piece falling upon the ground 23 become dust, worth nothing. Are you clear?”
“I see. Now I’m ready. ” said the beggar with confidence.
“Then you should 24 ! It’s obvious that your wallet is a/an 25 one, so don’t load it too heavily,” said the Goddess Fortune.
The excited beggar could hardly 26 to have gold. He quickly opened his wallet, and a 27 of yellow coins was poured into it. The wallet became heavier and heavier.
“Is that enough? Isn’t it cracking? Will your wallet strong enough for more?” warned the Goddess.
“Never 28 .It’s still strong enough now” replied the beggar firmly.
The wallet was filled with so many coins that the beggar’s hands began to 29 . “Ah, if only the golden stream would 30 forever! Just a little more,” said the beggar, “ 31 just a handful or two.”
“There! It’s full. The wallet will 32 .” warned the Goddess again, but the beggar insisted, “ I know it will 33 a little more, just a little more.”
One more piece was added and the wallet split. The 34 fell upon the ground and became dust. The greedy beggar had now 35 but his broken wallet.

Nowadays it is found that school students seldom pay much attention to sports. Is it because they have no 32 in sports? It may not be the fact. They often say they have 33 more important things to do.
34 are these important things? Examinations! They have to 35 themselves for the most important School Certificates of Education Examination(毕业会考), and also to 36 with the test and the exams in school. So many of them tend to 37 bookworms.
In the summer holidays of the former years they could do 38 they liked, but in the summer holidays of the 39 years, they have to 40 all their time to the preparation. So studies have 41 them from going in sports.
Because of the pressure 42 their parents and teachers, they have to work harder and spend most of their time on books. Many parents 43 their children to pass this examination in order to get a stepping stone for higher studies or better jobs. As for the 44 themselves, they want to get good results so that they can 45 their studies in the universities. So it is necessary that they 46 up their school activities, especially sports.
Indeed, a complete education cannot go 47 physical training, for a quick mind seldom 48 along with a weak body. It is well said, “All work no play 49 Jack a dull(迟钝的)boy.” In one word, without a strong body, you can never 50 anything, let alone a great success in 51

NASA’s twin Mars rovers, Spirit and Opportunity, have been exploring the Red Planet since 2004. But a little more than a year ago, NASA lost contact with Spirit. The space agency has tried several ways to make contact with the rover, but Spirit has not sent back any signals.
Spirit landed on Mars on January 4, 2004. Three weeks later, Opportunity arrived. Soon after, the rovers went to the opposite side of Mars. Spirit’s original mission was only designed to last for three months, but Spirit has worked for more than five years doing additional missions. Both rovers have made important discoveries about ancient Mars. They have taken thousands of images and found evidence in the rocks of a water, warmer past in Mars’ history.
Spirit is solar-powered. It got stuck in a sand trap in April 2009, trapped deep into the soil and with its wheels turning around and around but not able to move forwards or backwards. Spirit had to agree that there is nothing that can be done to change the situation—it’s never going to move again. However, even if it is a not moving station, it can still study the planet’s atmosphere and deep interior.
NASA has been concentrating on trying to position its solar panels to get as much energy from the sun as possible, or to get the rover leaning in a manner that will allow the most amount of sunlight falling on its solar panels, in order to keep it alive during the coming winter months. Engineers have planned to rock the vehicle back and forth to acquire a more favorable position. However, no matter how many efforts have been made, Spirit still could not get out of the soft soil and could not lean itself toward the sun as the Martian winter approached. Without enough energy reaching its solar panels and with so little energy in its batteries, it went into hibernation, just like a polar bear, and has not communicated with Earth since March 22, 2010.
Whatever the future holds for Spirit, its mission has been an outstanding success. When it landed on the Red Planet in January 2004, no one was really sure how long it would continue working in the cold and dusty environment. As a matter of fact, three months was its original goal.
After so many fruitless efforts, NASA scientists are losing hope of ever reconnecting with Spirit, but they will give it one more try. Ground controllers are contacting Spirit over a range of frequencies and at different times during the day in case its internal clock stopped working and it lost track of time. They also are commanding the rover to turn on its backup radio transmitter in case the main one is dead.
If this final effort to connect isn’t successful, NASA will shift the focus to its twin robot, Opportunity, which is in a different part of Mars. Opportunity is still on the move and continues to travel freely to this day. It has traveled 16.6 miles so far, and is currently rolling towards another crater it has yet to explore.
NASA has spent more than $900 million on the project but shows no sign of giving up on these determined and hard-working robots. The rovers are, though, experiencing gradual wear and tear, the expected damage to something caused by using it repeatedly over a period of time. Even before Spirit got trapped, one of its wheels had failed. And NASA says it’s just a matter of time before both robots break down completely.
