Is there anything strange on the top of the world's highest mountains? If so, is it a bear? Is it a monkey? Or is it a kind of man?

    No one 1. The world has tried their best to know more about this mystery (神秘) for years. In 1887, 2 mountain climber found very big footprints of a very large man. 3 man doesn't walk barefoot（光脚）in the snow. In 1906, 4 climber saw more than footprints. To his surprise, he saw a great hairy animal 5 on two legs. As he watched, it ran out of sight（视线）.

    Fifteen years later, there were 6 about the thing in the newspapers. A mountain climber said that he had seen the “snowman”   7 slowly across the snow, far below him. He said it looked like a very large hairy man.

    From that time on, more and more people had stories to tell. But not until 1951 did a mountain climber bring back 8 of giant (巨大的) footprints. The picture showed 9 that the snowman walked on two legs. So it was not a bear or a monkey. Could it be an ape man? The mystery grew!

    And the mystery keeps on growing. 10 men still hunt the snowman in the high mountains. Some day we may find out just what it is that makes the giant footprints.

    China has made big progress in running competitions! The young 1 Su Bingtian made history on Sunday by becoming the 2 Asian athlete to appear in the men's 100m final at the world athletics championships.

    As the 3 man in China, Su was born in a 4 family in Guangdong in 1989. His parents were both farmers and had a lot of work to do on the farm every day. So Su often helped them with housework at home. Though his study was not very good, he was 5at running than many other boys in his class. He6 this kind of sport very much, so he practised running as often as possible. In 2004, Su started to take part in different competitions and has won many prizes since then. And this year, he managed* to finish 100 metres in 9.99 7. That was the best result in Asia. His dream8! When he heard the news, he could not believe 9 ears.

    Though Su is famous now, he never behaves arrogantly*. Instead, he still works hard 10 he wants to have a better chance of winning! I believe there is a lesson there.

    At my heaviest I weighed 370 pounds. I had a very poor relationship with food: I used it to1bad feelings, to make myself feel better, and to celebrate. Worried about my health, I tried many different kinds of diets but nothing worked. I came to believe that I could do nothing about my weight.

    When I was 50, my weight problem began to affect me2. I didn't want to live the rest of my life with this extra weight any more.

    That year, I3a seminar(研讨课) where we were asked to create a project that would touch the world. A seminar leader shared her4story —she had not only lost 125 pounds, but also raised ＄25,000 for homeless children.

    5by her story, I created the As We heal(痊愈), the World Heals project. My goal was to lose 150 pounds in one year and raise $50,000. In this way, I could not only heal myself but heal the world by supporting a movement set up 30 years ago to end hunger.

    6I began my own personal weight program, I was filled with the fear that I would run into the same difficulties that beat me before. While the7hung over my head, there were also signs that I was headed down the right path. I sent letters to everyone I knew, telling them about my project. It worked perfectly. Donations began 8in from hundreds of people.

    Of course, I also took some practical steps to lose weight. I hired a fitness coach. I began to eat small and9meals and exercise often.

    A year later, I10my goal: I lost 150 pounds and raised $50,000! I feel that I've been given a second life to devote to something that is meaningful and great.

    Four women lived in the same building and all of them were going to a party. They were 1about what dresses they would wear. They final decided to choose a dress that matched the hair colour of their own 2.

    The first woman said, "I will go in red 3 my husband coloured his hair red."

    4 this, the second woman said, "Well, I will5 black because the colour of my husband's hair is black."

    The third woman also had a(n) 6, "Yes, then I would love to go in a 7 dress because my husband has yellow and blonde(金色的)hair!"

    They all turned to the 8 woman, but she stayed quiet. So they asked her 9 she would wear." I am thinking very hard, but I can't 10 a right dress. It seems that I can't wear any dress. I use my husband is bald(秃头的)!" said the woman.

Last year in early summer, I was walking up the hill to my house when I saw two birds, each about 60 centimeters tall, standing on the road. They didn't seem to 1  me until I was right in front of them and then they at once moved 2 into the trees.

I was quite excited by the idea of two 3 making a nest(鸟巢) in my front yard, although I didn't really expect them to 4 wild birds don't usually nest so close.

A few weeks later, the birds 5 again. I found them crouching (蹲伏) beside a tree. As I moved nearer to them, I 6 that they would run away like they did last time. But instead they stuck out their heads and made a threatening (威胁的) croaking sound. It seemed to warn me not to go any 7 .

I didn't know why they were croaking at me until a short time later I made an amazing 8 : they had two small baby birds.

As I moved quietly towards the birds, 9 not to make any sudden movements, they started their croaking again. They straightened their necks forward so they seemed 10 and more threatening. The mother looked at the babies, and 11 them well in her feather (羽毛).

I was watching them 12 respect when I suddenly tripped and fell to the ground. The birds took this as a threat and the father raced towards me, 13 his wings to protect the mother and the chicks while making himself appear larger.

I was 14 to have surprised them and left quickly. I was amazed by their fearless actions. Their parental natural ability kicked in and made them so brave. It is hard not to 15 nature.
