How airplanes fly?

People {#blank#}1{#/blank#} (try) for a long time before they invented a {#blank#}2{#/blank#} (success) "flying machine". Now there {#blank#}3{#/blank#} (be) so many {#blank#}4{#/blank#} (plane) in the sky.

    An airplane {#blank#}5{#/blank#} (fly) because of the upward force(力量) of {#blank#}6{#/blank#} (move) air against its wings(翼). To get that moving air, it needs something {#blank#}7{#/blank#} (push) it forward—like a motor-driven propeller(螺旋桨) or a jet engine(喷气发动机). You can fly a kite if there  {#blank#}8{#/blank#} (be) enough wind to hold it up. An airplane is like a kite with such force!

    More and {#blank#}9{#/blank#} (many) young people are getting to like making model planes now. How about you? Are you interested in it after {#blank#}10{#/blank#} (read) this article?

    The Old Man and the Sea is a short novel written by the American author Ernest Hemingway in 1951 in Cuba. It tells the story of a fight between an aging fisherman and a giant marlin (枪鱼). The novel opens with the fisherman, Santiago, who has gone 84 days without catching a fish. He is so unlucky that his young apprentice (徒弟), Manolin, hasn't been allowed by his parents to sail with the old man. On the 85th day, Santiago sets out by himself, far onto the Gulf Stream. He sets his lines and by noon, a big marlin takes his bait (鱼饵). After three days' struggle with the fish, Santiago manages to tie the marlin to the side of his boat. While Santiago sails back to the shore, sharks are attracted to the blood left by the marlin in the water. Though Santiago makes a great effort, they have almost eaten up the marlin. Santiago knows that he is defeated (打败) and tells the sharks of how they have killed his dreams. Once home, he is so tired that he goes straight to bed and falls into a deep sleep. Manolin feels much worried. The next day he brings him newspapers and coffee. When the old man wakes, they promise to fish together once again. The old man doesn't feel well and also coughs up blood a few times towards the end of the story. Readers think that the story is about man's fight against the natural world. In the story, Santiago and the marlin show similar qualities of pride, honour, and bravery, and both have to obey the same natural law—they must kill or be killed.

    The novel has received so much praise and is considered to be one of Hemingway's most famous works. It was awarded the Pulitzer Prize for Fiction in 1953 and the Nobel Prize for Literature in 1954.

    Britons are well known for drinking tea. The average (典型的) person in the UK drinks around 1.9 kg of tea every year. That's around 876 cups of tea. Tea is drunk by all levels of society. But tea does not grow in Britain. Most tea grows in India and China. So, how did it become an important part of British culture?

    Tea arrived in London in the 1600s. At this time, British ships were exploring the world and came across the drink in China. It was not long before green tea could be bought from the market. However, it was only for the rich people.

    At the beginning of the 1700s, the amount (数量) of tea arriving in Britain increased rapidly. Black tea arrived at this time. At first this tea served exactly as it was in China. They soon discovered that it mixed really well with a little milk and sugar, giving the drink a special British colour.

    In the 1800s, tea was still a product enjoyed only by people with money. At this time, they began to have "afternoon tea". They drank tea with a snack around 4 pm to avoid feeling hungry between lunch and dinner. It is a still going today but has become less popular in recent times.

    Alice and John are in the music club at their school. Alice plays the violin and John plays the drums. There are two groups in the school music club: the training group and the concert group. Everyone starts in the training group!

    "When I first started to play the violin it sounded terrible!" Alice said. "My family asked me to practice outside."

    After a year's practice, Alice and John play much better. Now, they are both in the concert group and they are learning more difficult music. "We're learning the music from the film Pirates of the Caribbean. It sounds fantastic!" John said. "Playing in the club with other kids is a lot of fun."

    Playing an instrument (乐器) is not only fun. It also helps children learn to concentrate (集中注意力). "I have to concentrate when I'm practicing," Alice said. "And now it's easier for me to concentrate on my schoolwork."

    Playing an instrument can also help children become more confident. As John said, "I was scared when I played in front of a lot of people for the first time. But now I really enjoy it."

When you look at me now, you won't believe that I once weighed over 300 pounds. Yes, I used to be a really 1 girl. I never worried about it until I had a medical examination one day. 

The doctor told me that I was having heart trouble. He said it would be 2 if I could lose some weight. Then I decided to make a 3 .

After a year and five months, I lost 104 pounds. I didn't have any expensive food, medical treatment or camp- style exercise. So what was the secret to my 4 ?

First, I looked through the Internet for some 5 on losing weight. Of course, I saw many advertisements(广告), but I bought nothing. The only thing I did was change my bad6 . I stopped having drinks with too much sugar and 7 my love for sweet cakes. Now I have got used to eating a lot of green vegetables and using vegetable oil only. I 8 eat after 6:30 p. m. because it's unhealthy to have a late dinner. Also, I 9 for 15 to 20 minutes five days a week to keep fit. 

People sometimes say, " You don't need to tell me what to do. I've known it already!" The fact is that knowing what to do and doing what you know are completely 10 . The important thing is to know what to do and then keep doing it.
