When you are about to do something brave, a cheerful wish of "Good luck!" from a friend can be helpful. But if you think you need lots of luck, what else might you do?

    In the UK and US there are some strange traditions for bringing yourself a little more good luck. Some are hundreds of years old and some are much newer.

    Have you heard the saying "When you wish upon a star"? If you are looking up at the sky on a clear night and you see a sudden flash of light, it is probably a shooting star! Seeing one doesn't happen very often. The saying goes that you have been very lucky if you see one, and so if you make a wish, it will come true.

    Maybe you have heard of the lucky  rabbit's foot. Some people believe that rabbits are lucky animals, so they carry a part of the rabbit, its foot, for good luck. There are all kinds of strange, unclear rules about which of the rabbit's feet is the luckiest. It is said that this good luck tradition is the oldest one of all. However, as the funny saying goes, "Depend on the rabbit's foot if you will, but remember it didn't work for the rabbit!"

    People in Britain love trees. If it is autumn and leaves are falling from the trees, some people try to catch the leaves as they fall because they think each leaf they catch will bring them a lucky month in the following year—they will need to catch 12 falling leaves to have a whole of good luck!

    Nobody knows how many different languages there are in the world. The most widely used language is English. It's used by business people, airline pilots all over the world. It's also the first language of sports and science. So it's very important for us to learn English.

    English is most widely spoken in the world, while Chinese has the largest number of speakers. There are not only over one billion people living in China, but also many Chinese people living outside China. You can find large or small groups of Chinese people living in almost every country in the world.

    There are some other important languages in the world, too. Chinese is of course very important, especially in Asia. Arabic is widely spoken in many parts of Asia and Africa. Russian is spoken both in Europe and Asia. French is widely understood, not only in Europe, but also in parts of Canada, Africa and Asia. Spanish has a growing number of speakers all over the world, especially in Central and South Africa.

    What language do people speak in the United Nations? There are so many different languages in the world, but they decide to use only six of them. They are Arabic, Chinese, English, French, Russian, and Spanish. Everything spoken or written in one language is translated into the other five.

Nowadays in school life, a lot of students develop a fear of tests. It's not because tests are something to be afraid of. Most students are afraid of tests mainly because they don't always think they are well—prepared and they don't have enough self—confidence. If you follow the advice below, it's not difficult to overcome your fear of tests.

People who know that they are not well—prepared are usually those who fear tests most. However, most students don't know when they are truly prepared for a test. As long as you know that you have studied well and long enough, you have reason to believe that you are well—prepared.

Be confident about yourself. Confidence before a test can bring about two results: either you fail the test and feel as if your confidence was unfounded (毫无根据的) or you could actually do well in the test because of your confidence. Some students find that they experience the first result. However, this is only because those students might not have followed the first advice mentioned above. As long as you have studied well, you will be more confident of your chance to succeed in a test. If you feel as if you have not studied hard enough, then you will not be as confident as you should be.

Ask your teacher in advance (提前) about the material that is going to be covered in the test. In this way, you will know what you should prepare for and you can get confidence in the test. But you have to be brave enough to ask. Most students do not ask unless their teacher gives the information first, so make sure that you ask.

You should know that tests are only telling if you have got the knowledge, not how good or bad your IQ is. So, even if you do badly in one test, you should know that there are other tests to come. As long as you think that there is another tomorrow, you can overcome your fear of a test. However, make sure that you are going to prepare well for the other tests.

Fear can be a problem in the process of achieving success. However, with the right attitude (态度) and preparations, you can overcome your fear of tests by using these suggestions.

    Schools in the UK are quite different from those in China. In the UK, at the beginning of the term, students must select their courses and teachers first.

    {#blank#}1{#/blank#} So in the first term, don't select too many courses, or you'll feel nervous and it may influence your study. Then you have to ask for some teaching plans. There is some information about subjects, time arranging, marks and textbooks. {#blank#}2{#/blank#} Different teachers have different teaching methods.

    If the teacher is called "killer" by the last grade, many students will give up choosing him, because this kind of teacher will leave too much homework, give too many exams and too low grades.

    {#blank#}3{#/blank#} How to buy textbooks makes each student feel hard. The textbooks in the UK are very expensive. Each copy is about $30 -50. In order to save money, many students buy some used textbooks. {#blank#}4{#/blank#}

    In class, discussing is very important. The teachers always encourage you to ask questions or show your own opinions freely. They don't usually ask you to sit well. {#blank#}5{#/blank#} They usually don't give you much homework to do. So in the schools in the UK you can learn knowledge and do exercises by yourself. You must do almost all things independently.

A. And some students usually borrow textbooks from the school library.

B. At the same time, you must select the teachers.

C. Selecting is very important for your grades in the UK.

D. Instead, they allow you to sit or stand everywhere you like.

E. There is another thing after you select the courses and the teachers.

What did people do to communicate in ancient times? Here are some very interesting answers to this question.

Alphorns（阿尔卑斯长号角） were once used to communicate in the mountains in Switzerland. They are very long and they are very heavy, too. So, alphorns are hard work to blow. Then why use them? Well, they make a loud sound which travels much further than the human voice. Herdsmen（牧民） used them to call cows in the distance for milking. At sunset, alphorns were also used to send a message down to villagers that all was well. These days, they're mostly used as musical instruments.

The people of La Gomera, an island in Europe, have their own special way of sending messages from mountain to mountain. They use a whistled（口哨） language called el silbo, which comes from their language Spanish. Whistling can be heard within five kilorneters, which means it can be used across much greater distances than shouting. El silbo can be used for all kinds of messages, including greetings and announcements. El silbo is used a lot less than it used to be, but primary school students in La Gomera have to leave it.

Did you know it 's also possible to send messages without making a noise? This is called visual communication, and it includes the use of flags and even smoke. Long ago, soldiers along the Great Wall of China used smoke as a warning. If they noticed the enemy from their signal（信号） tower, they lit a smoky fire. When soldiers in other towers saw the smoke signal, they lit fires, too. In this way, messages about the enemy's arrival could travel as far as 800 km in just a few hours.
