                                                         Learning a Second Language

   Some people learn a second language easily. Others have trouble learning a new language. How

can you help yourself learn a new language, such as English? There are several ways to make learning

English a little easier and more interesting.

   The first step is to feel positive about learning English. If you believe that you can learn, you will learn.

Be patient. You do not have to understand everything all at once. It is natural to make mistakes when

you learn something new. We can learn from our mistakes. In other words, do not worry about taking

risks.

to writing it in English, and you will feel comfortable expressing your ideas in English. Several weeks later, you will see that your writing is improving. In addition, you must speak English every day. You can

practice with your classmates outside class. You will all make mistakes, but gradually you will become

comfortable communicating in English.

   The third step is to keep a record of your language learning. You can write this in your journal. After

each class, think about what you did. Did you answer a question correctly? Did you understand

something the teacher explained? Perhaps the lesson was difficult, but you tried to understand it.

every day and make a record of your achievements. You will enjoy learning English, and you will feel
