阅读下面短文，并按照题目要求用英语问答问题（请注意问题后词数要求）。

Making friends can be difficult, especially these days with so many peer pressures. If you want to develop a more pleasing personality and make friends，become genuinely(真正地) interested in other people and show kindness. You may be wearing the latest designer label clothes，the hottest brand shoes and the coolest jewelry, but if you display sourness and selfishness you’ll have a battle ahead of you to make good friends.

Smile...smile and continue to smile. It costs nothing, enriches those who receive it, happens in a flash(闪烁)but the memory lasts forever；it creates happiness in the home and classroom. A smile can not be bought，begged or borrowed，it comes from the heart. If you want other people to like you, make the other persons feel important, and do it sincerely!

Choose your friends carefully. If others try to persuade you to smoke, take drugs, steal，gamble, fight etc...dare to say NO. Doing the wrong thing is the quickest way to lose friends，especially honest, good and upright friends.

Being mentally strong is not always easy but let me assure you that the more you practise it，the easier it becomes. Soon those who thought they were trendy will want to dress like you，talk like you and be with you because you have a personality which is different. People like being different! By being an individual with your own personality you can achieve the very best experiences in your life. You may not ever have many friends but let me tell you that it is better to have one good friend than ten dishonest friends who will stab you in the back at the very first opportunity that arises.
