1 . I fell in love with Yosemite National Park the first time I saw it. My parents took us there for camping. On the way out, I asked them to wait while I ran up to El Capitain, a_________rock of 3,300 feet straight up. I touched that giant rock and knew_________I wanted to climb it. That has been my life’s passion(热爱) ever since—_________the rocks and mountains of Yosemite. I’ve long made Yosemite my_________.

About 15 years ago I started seeing a lot of_________, like beer cans, empty boxes, around the area. It’s beyond me why visitors started respecting the place_________and treated such a beautiful home-like place this way.

I tried_________trash(垃圾) myself, but the job was too big. I would_________an hour or two on the job, only to find the area trashed all over again weeks later. Finally, I got so tired of it that I decided something had to change.

In 2004, together with some climbers, I set a date for a_________. On that day, more than 300 people__________. Over three days we collected about 6,000 pounds of trash. It was amazing how much we were able to__________. I couldn’t believe the__________we made—the park looked clean!

Each year volunteers come for the cleanup from everywhere. In 2007 alone, 2,945 people picked up 42,330 pounds of trash.

I often hear people__________about their surroundings. If you are one of them, I would say the only way to change things is by__________rather than complaining. We need to teach by__________.

2 . Ann’s neighbour Tracy found a lost dog walking around the local primary school. She asked Ann if she could keep an eye on it. Ann said that she could _______ it only for the day.

Tracy took photos of the dog and printed off 400 FOUND fliers（传单）and put them in mailboxes. _______ , Ann bought some pet foods in the dollar store nearby, and _______ her two sons not to fall in love with it. At the time, Ann’s son Thomas was 10 years old, and Jack, who was _______ from a heart operation, was 21 years old.

Four days later Ann was still _______ the dog, whom they had started to call Riley. When she arrived home from work, the dog _______ itself against the screen door and barked madly at her. As soon as she opened the door, Riley _______ into the boys’ room where Ann _______ that Jack was suffering a heart attack caused by the operation. Riley ran over to Jack, and when Ann bent over to help him, the dog went _______ .

“If it hadn’t come to get me, the ________ said Jack would have died,” Ann reported to a local newspaper. At this point, no one had called to claim the dog, so Ann decided to ________ it.

The next morning Tracy got a call. A man named Peter ________ his dog and called the number on the flier. Tracy started ________ , and told him, “That dog ________ my friend’s son.”

Peter drove to Ann’s house to pick up his dog and saw Thomas and Jack crying in the window. After a few moments Peter said, “Maybe Odie was supposed to ________ you: maybe you should keep it.”

3 . Last night my husband and I were walking when we saw a man bending (弯腰) over on the ground, crushing (碾碎) something with a rock. He was so focused on his ________ that he didn’t look up at anyone passing by. We kept noticing him and ________ what he could be doing. I thought he was crushing stones to make sand, but why would he do that?

________, we decided to go up and ask him. He was crushing pieces of left-over bread that he had ________ to prepare food for the birds that come there early morning. The large pieces of bread would be ________ for the birds to eat so he crushed them into powder. Every ________, after coming home from his job as a tailor, he goes ________ the villa (乡间别墅), collecting left-over bread from all his neighbors. He then eats a quick meal and comes here, and spends the next 1-2 hours carefully crushing each piece and makes a neat pile for the birds. He has been doing this for the last 3-4 years, which ________ us a lot. When we told him that we took an interest in this, he felt ________, since for him it wasn’t a big ________.

When we asked him what encouraged him to do this act of ________, he said, “It’s just something ________ I do, so that the left-over bread doesn’t go into the rubbish and the birds get food.” We ________ his story with the hope that it would ________ us to be aware of leftovers too and that it might ________ someone to start something similar in their own area.

6 . Heimaey is a small island off the southern coast of Iceland. But with its neighbouring islands, there ________ the world’s largest puffin colony (海鹦群). Each spring, puffins go to the islands to breed (繁殖). Around August, baby puffins ________ their way to the ocean. That’s when the ________ begins.

Baby puffins leave at night by instinct (本能) and follow the light of the ________ to the sea. But they are ________ by bright lights. Every year, a large number of baby puffins ________ lost. Worse still, the lost birds are ________ hit by cars or eaten by cats.

Each breeding season, the ________ of Heimaey start their own midnight adventure, which is called the Puffling Patrol. They formed search parties. ” When you see a bird, you try to ________ it and guide it into the box, “ Eldur Hansen, a 14-year -old boy says.

The next morning, they take the birds to the beach for release(释放). Over the years, kids have even developed a ________ method. ”You do not throw them like a baseball,“ Eldur says. ”You hold them in both hands. Then spread your arms out in front of you and let go. “ Before being set free, the birds are ________ and tagged(打标签) for tracking purposes.

“ Thanks to kids’ help, we scientists have learned that baby puffins now weigh less. That means they have a ________ chance of survival , ”says Erpur Hansen, Eldur’s dad, a researcher in the Southeast Iceland Nature Research Center.

Scientists worry puffins will ________ completely. But the kids give ________ to Erpur Hansen. “The story is that people can make a(n) ________”he says.     Each time these kids help a bird get back to the ocean, they show us that.

10 . Adventure is in my blood. And I had been considering how I was going to celebrate my high school graduation. I didn’t just want a small_________in the backyard. I started thinking about doing a solo_________somewhere out of the ordinary. I took out the map and drew a 1,500-mile_________along which I would be_________from the northernmost point in Norway to the southernmost section of Sweden. When I_________ my plan with my dad, he_________as I thought he would. Because I get my adventurous_________from him, he was all for it.

I had only been away from my home for three days, but there was an inner_________going on. Part of me was homesick and doubting whether I really could_________ it. The other part of me was ready to__________to myself and my family that I could do it by myself.

On the road, I met another bicyclist who was quite a bit older than I was. He started his journey alone by bike at the southern part of Norway and last finished. I could tell he had a great sense of__________. It encouraged me not to__________.

As I listened to my favourite artists on my MP4 player, I pedaled with my feet. There was nobody around me for miles.____________, that wasn’t entirely true. There were mosquitoes, millions of them. My arms were so dotted with__________ that they looked like a topographical (地形的) map. But however__________it would be, nothing could stop my advance on the destination. As you know, adventure is in my blood.
