In classes, your teachers will talk about the topics that you are studying. The information will be important for you to know when you take tests. So you must be able to take good written notes from what your teachers say.

Here are three stages (阶段) of taking notes and what you should do during each stage.

Before class

Review (复习) your notes before you come to class. This will be good for remembering what was covered. Get you ready to understand new information your teacher will provide.

During class

Keep your attention (注意力) on what your teacher is saying. Be sure to include in your notes information that your teacher repeats or writes on the blackboard. Write quickly so that you can include all the important information in your notes. Do this by writing abbreviations (缩写) such as med for medicine, using symbols such as % for percent, and writing short sentences.

After class

Rewrite your notes to make them more complete and accurate (准确的) by changing abbreviations into whole words, symbols into words, and shortened sentences into longer sentences. Use them to answer your questions. If necessary, ask your teacher for help.

Are you happy? Perhaps some of you will say “no”. In fact, being a teenager is hard. You may worry about a lot of things in your life.

Do you know what British teenagers worry about most? You can find the answer from the chart below. The research was done by the UK’s Department of Health among more than 100,000 teenagers. Here are the results.

Many Chinese teenagers share similar worries with the British teenagers. A recent research shows that many Chinese teenagers suffer from social life, study and emotional problems.

To solve the problems, some schools came up with the idea of happiness education. For example, Tsinghua University High School tried to meet students’ needs. It built a skating rink and different laboratories to develop their interest.

While schools take action, students themselves can do something, too. The professor Nadia Lovett from Australia believes students’ habits, hobbies and attitude toward life all play a role in their happiness.
