请认真阅读下列短文，并根据所读内容在文后表格的空格处填入最恰当的单词。注意：每个空格填1个单词。 As a saying goes, a warm and loving hug to embrace(拥抱) you. Man is a social animal by nature. We all need friends, as they are there for us when we need support, just as we are there for them whenever they need us. Therefore, it is necessary for you to know how to make friends. The first step is to open yourself up. If you want to make good friends, you should be able to share your thoughts and feelings with other people first. Only when you share something of yourself with others, can you begin making friends. When your friends open a conversation with you, they are usually expecting you to share information in return. That is to say, when you are in a conversation, you’d better express your own thoughts and feelings. If a conversation is one-sided, the person doing all the talking may think the other person is not interested in what he is saying. So, when talking with your friends, be sure that the conversation is a two-way street. One of the most important keys to building a solid friendship with other people is to listen to them—really listen. When your friends tell you something that happened to them or complain（埋怨） about a situation, they are usually not looking for agreement but just want to be heard. So don’t try to change their mind or solve their problems, just let them know that you are listening to them. Respecting your friends is also important to keep your relationships healthy and strong. Looking at your friends while they are talking to you is one way to show your respect, as they will feel that what they are saying is important to you. Unconditional support and encouragement is one of the things which friends have. True friendship means offering a shoulder when they need it, crying with them when they are sad, and laughing with them when they are happy. Only in this way, can the tree of friendship last for a long time.
