Making friends is a skill. Like most skills, it    with practice. If you want to meet people and make friends, you must be willing to    some actions. You must first go where there are people. You won’t make friends staying home     .
Join a club or group, talk with those who like the same things    you do is much easier. Or join someone    some activity.
Many people are nervous when talking to new people.    all, meeting strangers means    the unknown. And it’s human nature to     a bit uncomfortable(不舒服)about the unknown.
     our fears about dealing with new people come from doubts(怀疑)about      . We imagine other people are judging us, finding us too tall    too short, too this or too that, but don’t forget that they must be feeling the same way. Try to accept yourself     you are, and try to put the other person at ease(不拘束).You’ll both feel more comfortable.
Try to    self-confident(自信)even if you don’t feel that way when you    a room full of strangers, such as a new classroom, walk tall and straight, look directly    other people and smile.
If you see someone, you’d like to    , say something. Don’t wait for    person to start a conversation(谈话).
Just meeting someone new does not mean that you will    friends with that person. Friendship is based on mutual(相互的)liking and “give and take”. It    time and effort to develop. And there are things that keep a new friendship from     .
