Making friends is a skill．Like most skills，you can improve it if you are patient．If you want to meet people and makes （61）friends，you must be willing to take action．You must first go where there are people．You won't make friends staying home alone．
Joining a club（62）or a group，talking to those who like（63）the same things as you do is much easier．Or join someone in some activities．
Many people are nervous when you talk（64）to new people．After all，meeting strangers means seeing the unknown．And it's human nature to feel a bit unpleasant about the unknown．Most of fears about dealing with new people come from doubts（懷疑） about ourselves．We imagine other people are judging us-finding us too tall or too short，too this or too that．But（65）don't forget that they must be feeling the same way．Try to accept yourself as you are，and try to make others feel at home．You'll all feel more confident（66）．

If you see someone you'd like to speak to，say something．Don't wait for（69）the other person to start a conversation．
Just meeting someone new does not mean that you'll make friends with that person．Friendship is based on mutual（相互的） likings and"give and take"．It takes（70）time and effort（精力） for us to develop friendship．And there are things that stop a new friendship from growing．
