II. READING Read the passage and then answer the questions. (Đọc đoạn văn và sau đó trả lời câu hỏi.) We can communicate not only through words but also through body language. Body language includes our posture, facial expressions, and gestures. Because body language is so important, you’ll want to know what yours is saying and how to interpret other people’s, too. Here are some examples of body language and its meaning. If your posture is slumped and your head is down, this could mean that you are sad or you lack confidence. If your posture is straight but relaxed, you are expressing confidence and friendliness. A smile is a sign of friendliness and interest. But people sometimes smile just to be polite. To get another clue from people’s faces, notice their eyes. Friendliness and interest are expressed when a person’s eyes meet yours and then look away and meet yours again. A person who doesn’t look away is expressing a challenge. A person who doesn’t look at you is expressing lack of interest or is shy. Hand gestures can mean a person is interested in the conversation. But repeated movements - like tapping a pencil or tapping a foot - often mean the person is either impatient or nervous. Stay away from someone who points at you while talking with you: That person might be angry at you or feel superior to you. 1. How can we communicate?

Many people still believe that natural resources will never be used up. Actually, the world’s energy resources are limited. Nobody knows exactly how much fuel is left.
