Earth is our home. It has air that we can breathe(呼吸). It has water for us to drink. It has plants and animals that we can eat. Earth is not too hot or too cold for us. It has everything we need to live.

    We are on earth, but we call see things that are not on earth. Early in the morning, we can see the sun comes up. All day, the sun seems to move across the sky. Later in the day, we can see the sun goes down. But the sun is not really moving around us. We are the ones who are moving. Every morning, we turn towards the sun. Every night, we turn away from it. Every year, we go around it. Earth is our spaceship. All of us in the spaceship are riding around the sun.

    At night, we can often see the moon and stars. From earth stars look like little points of light because they are so far away. But stars are really big. A star is a great mass of burning gas. It gives off light and heat. Our sun is a star.

    There are eight planets moving around our sun. Earth is the third planet around the sun. Some of the planets have moons. A moon goes around a planet just as a planet goes around a star. Earth has only one moon. Some planets have more.

    When Norman left high school, he went to a college to learn cooking for two years. He enjoyed cooking and was good at creating (创造) his own dishes. Then he got a job in the kitchen of a big hotel as an apprentice (学徒) for four years.

    ①Norman soon found that cooking in a hotel was nothing like cooking for his family at home. He needed to work in a hot kitchen for a long time every day. A lot of people couldn't stand it, but Norman enjoyed it. He always made new and unusual cakes on Friday. More and more people visited the hotel on Friday just ②________ his cakes. The hotel owner soon found out why.

    When Norman decided to leave the hotel, ③the hotel owner offered(提供) him more money and the position (职位) of the head cook. Norman took the position and saved most of the money he made. Finally, he bought his own hotel last year. Then he found he needed a lot more skills than just cooking skills. So he went to an evening school to learn business every Tuesday and Friday.

    Norman enjoys having his own hotel. But he also enjoys working in the kitchen and ④thinking up new creations when the hotel is not too busy.

    When the Titanic was built, she was the largest ship in the world. It had taken 50,000 men two years to build her. She was 269 metres long and as high as an eleven storey building. She was huge! In fact, the word "titanic" is often used to describe something which is "very powerful, strong, important or large".

    It was built because of increased tourists travel between North America and Europe. The Titanic was like a floating palace. Everything about her was beautiful and comfortable. She was also impossible to sink or that's what everyone thought.

    The Titanic left Southampton on the south coast of England for New York on 10 April, 1912. She stopped first in France and then in Ireland before setting off across the Atlantic Ocean. There were 1,632 passengers on board; 907 crew members(船员) looked after them.

    Four days after leaving Southampton, the Titanic's captain received not one but four icebergs(冰山) warnings.

    Icebergs are very dangerous for ships- only 10% of an iceberg can be seen above the water. But the water was clear and the captain decided to continue without reducing the ship's speed. At 11:40 p.m. the ship hit an iceberg, which cut a hole about 100 metres long underwater. The passengers were not told, but the Titanic could not survive this terrible damage.

    It was dark and freezing cold. The ship was filled with water. There was no time to waste. Women and children were told to climb into the ship's lifeboats. But there were not enough lifeboats for all the passengers. Finally, at 2:20 a.m. the Titanic sank to the bottom of the sea. 916 passengers and 673 crew members died in the icy water.
