Good Communication for Making Friends As a communication skills trainer, I've met a wide range of people. Some people have trouble associating with others and have difficulty making friends. So I would like to discuss two key points to making good friends. The first is to show respect and love for your friends through your words. Try to say things to others that would feel good to you if you heard them. For example, say things like, "Thanks for the great time" and "It was really nice to get to know you."If you are not good at speaking, then smiling and using body language to express your sincerity is also an effective way to communicate. Additionally, I recommend that when you meet someone new send them an e-mail or letter before the day is over to express how nice it was to meet them. The goal of good communication is to reach another person's heart and form a comfortable relationship. It is, therefore, based the premise that you get rid of your worries and become a bright and positive person. When there is static noise over the phone line, you can't hear the other person clearly, right? In the same way, when your mind is full of worries and you try to communicate with another person, you cannot give or receive messages accurately. For example, let's say you are still tied to a past wound of being betrayed by a friend and feeling hurts .Even if you meet someone new and he or she tells you, "Let's be good friends," you may not be able to accept it because you will hear a negative inner voice saying something like "I might be betrayed again" or "the person might have a hidden agenda."With this worry in your mind, you will not be able to make friends. If you can be refreshed and get rid of your worries, you should be able to sense others' thoughts and feelings without prejudice and build a relationship of trust. If you really can't let go of your painful past experience, then try to change your perspective on the experience. For example, try to think that it was a necessary lesson for you to understand others' pain. If you can think of the positive intention behind the event, then you will be able to view the experience favourably and feel better. The main topic of the passage is（） The effective way to communicate includes（ ） The effective way to communicate includes（ ） Which of the following statements is NOT true according to the passage? （ ） The example in paragraph 2 is intended to show that（ ） In the sentence "the person might have a hidden agenda" (para.2) ,the word "agenda" means（）
