It was four o'clock when we left Micatlan,and we traveled quickly until it became almost completely dark.It was our intention to return to our general quarters in Atlacomulco that night.We had a long journey ahead of us,especially because it had been decided there was no way we would try to cross the ravines again at night,since they were considered far too dangerous.Futhermore,an eclipse of the moon was expected,and,in fact,while we were crossing an open field,the moon appeared on the horizon,half in shadow,a rare and beautiful sight.

After a few hours of riding,we suddenly realized that we had lost our way,and worse still,had no way of finding it again.Night had fallen and there was not a single hut in sight,only great plains and mountains and the lowing of distant bulls all around us.We continued on ahead,trusting in luck,though it was difficult to say where she had brought us.By good fortune,our advance riders ran into two Indians,a man and a boy,who agreed to guide us their village and no further.

After an interminable and exhausting road,which we traveled at a brisk trot,the barking of several dogs announced an Indian village.In the dying light,we could just make out cane huts,firmly situated between the banana trees,with fenced gardens in front of each one.Our convoy stopped in front of one particular hut,a kind of inn or shop for alcohol,where a naked goblin-like figure,the ideal husband for a witch,was serving cheap brandy to the Indians,most of whom were already drunk.

We dismounted and threw ourselves to the ground,too tired to even think.Someone found us,God knows how,a cup of dreadful hot chocolate.We began to realize that we were completely lost,and so it was agreed to give up our attempt to reach Atlacomulco that night.Instead,we should head for the village of “E1 Puente”,where our guides know a Spanish family,made up of several unmarried brothers,who,without any doubt,would be delighted to offer us a safe refuge for the rest of the night.We remounted and began our journey,a little restored after the pause in our journey and the dreadful hot chocolate.

Where did we travel to?

A.El Puente. B.The cane huts. C.Atlacomulco. D.An Indian Village.

When we traveled at night_________.

A.there was a good guide leading us

B.there was a full moon in the sky

C.we could hardly see anything

D.we could see everything around clearly

When we lost our way we believed that_________.

A.we should stay where we were for rescue

B.we should go on to seek after our fortune

C.we should go back where we started

D.we should ask the Indians for help

When we reached the inn-like hut_________.

A.someone served alcohol and hot chocolate at once

B.we had a good sleep

C.we had a good drink

D.we were too exhausted to ask for anything

It was early morning. Peter Corbett helped Mark Wellman out of his wheelchair and onto the ground. They stood before El Capitan, a huge mass of rock almost three-quarters of a mile high in California's beautiful Yosemite Valley. It had been Mark's dream to climb El Capitan for as long as he could remember. But how could a person without the use of his legs hope to try to climb it?
Mark knew he couldn't finish the climb alone, but his friend Peter, an expert rock climber, would be there to lend a helping hand. He and Mark thought that it would take seven days to reach the top.
Peter climbed about 100 feet up and hammered a piton (岩钉) into the rock. Fastening one end of a 165-foot rope to the piton, he let one end of the rope fall down. Mark caught the rope and fastened it to his belt with a special instrument. This instrument would allow Mark to move upward, but would prevent him from falling even as much as a single inch. He next reached above his head and fastened a T-shaped bar to the rope, using the same kind of instrument.
Mark took a deep breath, pushed the T-bar up almost as far as his arms could reach, and began the first of the 7,000 pull-ups needed to reach the top. High above, Peter let out a cheer. “You're on your way.”
Seven years before, at the age of twenty-one, he had fallen while mountain climbing, injuring his backbone. The fall cost him the use of his legs, but he never lost his love of adventure or his joyful spirit.
For the first four days the two men progressed steadily upward without incident. But on the fifth day an unbearably hot wind began to blow, and as time went by, it became stronger and stronger, causing Mark to sway (摇摆) violently on his rope. But Mark kept on determinedly pushing up the T-bar and pulling himself up. In spite of that, he had to admit that he felt a lot better when the wind finally died down and his body touched solid rock again.
It took them one day more than they had expected, but on July 26 at 1:45 in the afternoon, the crowd of people waiting on the top went wild with joy as the two heads appeared. Mark Wellman had shown that if you set your heart and mind on a goal, no wall is too high, no dream impossible.

If you were to walk up to Arthur Bonner and say, “Hey, Butterfly Man,” his face would break into a smile. The title suits him. And he loves it.

Arthur Bonner works with the Palos Verdes blue butterfly, once thought to have died out. Today the butterfly is coming back — thanks to him. But years ago if you’d told him this was what he’d be doing someday, he would have laughed, “You’re crazy.” As a boy, he used to be “a little tough guy on the streets”. At age thirteen, he was caught by police stealing. At eighteen, he landed in prison for shooting a man.

“I knew it had hurt my mom,” Bonner said after he got out of prison. “So I told myself I would not put my mom through that pain again.”

One day he met Professor Mattoni, who was working to rebuild the habitat for an endangered butterfly called El Segundo blue.

“I saw the sign ‘Butterfly Habitat’ and asked, ‘How can you have a habitat when the butterflies can just fly away?’” Bonner recalls. “Dr. Mattoni laughed and handed me a magnifying glass (放大镜), ‘Look at the leaves.’ I could see all these caterpillars(蝴蝶的幼虫) on the plant. Dr Mattoni explained, ‘Without the plant, there are no butterflies.’”

Weeks later, Bonner received a call from Dr. Mattoni, who told him there was a butterfly which needed help. That was how he met the Palos Verdes blue. Since then he’s been working for four years to help bring the butterfly back. He grows astragals, the only plant the butterfly eats. He collects butterflies and brings them into a lab to lay eggs. Then he puts new butterflies into the habitat.

The butterfly’s population, once almost zero, is now up to 900. For their work, Bonner and Dr. Mattoni received lots of awards. But for Bonner, he earned something more: he turned his life around.

For six years now Bonner has kept his promise to stay out of prison. While he’s bringing back the Palos Verdes blue, the butterfly has helped bring him back, too.
