True friends are hard to find. Often you thought you could believe in someone, b   1   later he or she may let you down (让你失望).

A true friend is someone who will always be there for you. Through good times or b   2   times, they will stand by your side. They will not l   3   you alone when things get difficult. They will accept you without trying to change you. A friend will b   4   new and exciting things into your life and make it richer.

True friends will keep your worst secrets as you will keep t   5  . They will be honest and you can always believe in them. If you talk to someone who you believe in, you don’t have to w   6   about what you may say. We can enjoy this freedom only with friends.

Friendship is a two-way street. To find a true friend and keep the friendship b   7   you, you must do the same thing as well. Be there for your friends when they are in n   8   and share the good times with them. Offer them the same things they give to you. Friendship will break quickly if only one person is giving and p  9   effort into it.

You will find that there is nothing more valuable t   10   having a true friend by your side to share life with, just as someone says, “There is nothing on this earth more to be prized (珍惜) than true friendship”.
