Men have always wondered about the earth they live on and about the ①_____ above them.

    When early men looked at the night sky, they asked themselves a lot of questions. They looked at the moon, and wondered what this strange bright object in the sky was. They did not understand why it changed its shape from night to night. They looked at the stars and planets. They also wondered why some of them changed their positions, while others did not.

    ②他们也思考地球的形状。 Most early people believed the earth was flat.

    ③In different parts of the world, there were different ideas about the universe. The ancient Greeks were the first people to study the universe(宇宙) more scientifically. In the sixth century BC Pythagoras put forward the idea that the world was round. However, he could not explain why people at the bottom of the world did not fall off.

    It was not until the sixteenth and seventeenth centuries that scientists found the answers to some important questions. ④With the help of Galileo's telescope, people could see the sky more clearly, and find the positions of the stars and planets. Finally in 1665, Isaac Newton explained to the world what gravity (重力) was and people at last understood why they did not fall off the earth.

    In a school, you may hear a student saying in Chinese,“我对汉语很感兴趣。“ but you're not in China. You're in a foreign country. Like the student, many foreigners are learning Chinese. But it's not easy. The Chinese use a different character(汉字) for each word. People have to memorize about 600 characters before they can do even basic reading and writing. For foreigners, it's hard to memorize them. And the following chart shows the top 3 difficulties for foreigners while learning Chinese.

    However, Chinese is more popular around the world today. The long history and colorful culture of China attract many foreigners to learn Chinese. With the rapid development, China is staying ahead in many fields and is playing its role in the world.

    Chinese is becoming a global (全球的) language and its popularity has risen around the world. Many countries set up Chinese courses in their schools.

    For example, in the UK, students used to choose between Spanish, Latin, French and other foreign languages. But now schools encourage their students to study Chinese. The increase in popularity of Chinese has been surprising. 1031 people took Chinese language exams in 2001, and the number was 2062 last year, while 2561 people chose Spanish. It's predicted that studying Chinese in the UK could overtake (超过) Spanish in less than five years.

    Just like the foreigners do, we also learn foreign languages. Different languages carry different cultures. So exchanges are necessary. By learning a foreign language, we not only have a useful tool of communicating, but experience a new culture, what's more important, learning a foreign language well will help us tell our own stories to the world.

    English is the first language of several countries. However, it has many differences. British, American, and South African English are all spoken differently. In many English language courses, the British and American differences are taught. There are important differences between the two.

    Probably the biggest difference between American and British English is the vocabulary. Different words and expressions are used to talk about the same thing. For example, in the United States, people throw their garbage into the trash can. In England, people throw their rubbish into the dustbin. In Britain, people take a lift to the fifth floor. In America, people take an elevator.

    American and British grammar can be also different. For example, speakers of British English will ask "What did you do at the weekend?", but Americans usually say "on the weekend." In the United States people usually say "I've gotten a new car.", but in the UK they will say "I've just got a new car."

    The pronunciation in American and British English is also different, even when the spelling is the same. The word "tomato"—pronounced "to-mah-to" in British English—is a classic example of this.Vocabulary, grammar, and pronunciation are three ways English is different in different parts of the world.

    Learning all these is not easy, so English learners should just know that they are always there.
