    A very important world problem is the growth of population on the earth. The population of the world today is more than 6,500,000,000. That is a great number and we know it quite well. ①The important thing is not how large the population of the world is now, but is the rate(速度) of the growth. It is about 1.63% every year after the number of dead people has been taken away.

    To give you some ideas of the birth rate, look at the ②second hand of your watch. Every second, four babies are born in the world. Another baby! Another baby! Another baby! Another baby! ③You can not speak quickly enough to keep up with the rate of the growth of the population. It is growing faster and faster. So it goes on, hour after hour. In one day, people have to find food for about 350,000 mouths more.

    This great growth of population will make a big problem by the year 2050 — there will be as many as 7,500,000,000 people on the earth! So this is one of the biggest problems that you are going to meet in your life.

    Do you want to be happier? Well, you can do something about it. Some psychologists（心理学家）believe that 10% of your happiness is due to life conditions and 40% is the result of your own choices. Your own choices include how you manage your time at school, your relationships, your friends, your activities and your health. So you have a lot of control over how happy you feel. {#blank#}1{#/blank#} Here are some tips on how to do that.

    Surround yourself with positive（积极的）people. Spend time with positive people and your ideas will become active. On the other hand, good friends will encourage, support, and lift you up when you're down. {#blank#}2{#/blank#} That's also true for the people that we work with. 

    Don't try to be perfect. Remember that nothing can ever be perfect. {#blank#}3{#/blank#} Instead think about what you already have. Think about what you've already done. Think of where you are today as a step towards tomorrow. Don't try to be perfect, just try to do things well-with excellence.

    Focus on now. Don't think about all the things that can go wrong, like failing at school or your friend leaving you. Thinking like this only results in worry and stress, which is a waste of time and energy.{#blank#}4{#/blank#} Just worry about making today great, because the best way to be happy is just to enjoy each day.

    Compare yourself to yourself, not to other people. There will always be someone smarter, or richer, or better looking or more successful than you. There will always be someone with a bigger house and a bigger boat than you. Someone will always have more. Rather, look at what you have got and who you are, accept and value that. Work toward being a better one than you were last month or last year.  {#blank#}5{#/blank#} And you will feel a lot happier with, and about yourself.
