In Britain you are allowed to drive a car when you are seventeen. You have to get a special two-year driving license before you can start. When you are learning, someone with a full license always has to be in the car with you because you aren't allowed to drive the car on the road alone. You don't have to go to a driving school--a friend can teach you. The person with you isn't allowed to take the money for the lesson unless he's got a teacher's license.

    Before you are allowed to have a full license, you have to take a driving test. You can take a test in your own car, but it has to be fit for the road. In the test you have to drive round for about half an hour and then answer a few questions. If you don't pass the test, you are allowed to take it again a few weeks later if you want to. In 1970 a woman passed her fortieth test after 212 driving lessons. When you've passed your test, you don't have to take it again, and you are allowed to go on driving as long as you like, if you are healthy. Britain's oldest driver was a man who drove in 1974 at the age of 100.

    Before 1904 everyone was allowed to drive, even children. Then from 1904 car drivers had to have a license. But they didn't have to take a test until 1935. On the early days of car driving, before 1878, cars weren't allowed to go faster than four miles an hour, and someone had to lead the car with a red flag.

    As a teenager, I am often asked what I am going to be in the future. A lawyer? A doctor? Or a scientist? No, my ideal career is to be a teacher. One of the 1for that is I want to be a teacher like Mr. Chen.
    "Look! Do you know what it is? A-ha, it's the  2 ! And it will always move around the sun."Mr. Chen said and pointed to his head. He then touched the nose and 3 , "Can you tell me the name of this mountain? It is the highest mountain on Earth! What's the  4of it? Yes, it's 8844.43 metres…" I'll never forget my first geography lesson. He was  5 humorous that we all fell in love with his lessons   6. It's Mr. Chen who opened the door of geography for us.
    Generally speaking, most of the teachers are strict7students and sometimes a little bit demanding（苛求的）, not so with Mr. Chen. He is a lighthouse, showing us the way to the treasure of knowledge. He is a friend and easy to get  8 with, always encouraging us to speak out loud without 9our shyness and other disadvantages. He is an example, volunteering his time to students and other teachers.
     One day I happened to meet him in the hospital. Seeing the cut on his arm, I realized he was donating his 10. I was moved and was  11 another lesson, a lesson of love and devotion.
    Every time I see my globe（地球仪）, it would 12me of Mr. Chen. He is the most unforgettable teacher I have 13met and he will always be. Someday I hope I am  14  to be a teacher like him.
    Thank you, Mr Chen, thank you for making learning not a job but a joy.
    Thank you for helping me to discover what I do best and to do it even  15Thank you for understanding all of us and giving us the time and care each of us needs.
