    In the morning, our art teacher, Mrs. Wang3the classroom and says, "Boys and girls, today we'll have a class in the zoo. You can see your favorite animals and draw pictures of4there."

    Then we take a bus to the zoo. After we5there, we see so many animals. Some6eat bamboo (竹子). They are so cute. Tom7a picture of them. Jenny's favorite animals are monkeys (猴子). She wants to see them first.8those monkeys are in the trees. They don't come9, so Jenny can't see them. She doesn't know what to do. Peter is very10.He asks Jenny to give (给) these monkeys some bananas. Then all the monkeys come to them. All of us are happy to have the class in the zoo.

    In the time it takes you to read this sentence, the population of the Earth will have grown by 10 people. That may not sound much, but it is about 14,000 people an hour. That is the same as adding most of the population of Germany to the world every year!

    Most of these new people are born in developing countries. These countries are found in much of Africa, South America, and parts of Asia. In the developed countries of Europe and North America, the population is growing very slowly. This is because women in these countries have, on average, only one or two children. In the developing countries, many women have five or more children. In 1950, around one quarter of the world's population lived in the developed countries. By 2050, these countries will be the home to only around one tenth of the world's people.

    In the developing countries, more than one billion people already live below the poverty line (贫困线).These people don't have enough food to eat and they live in poor housing; children get little or no time at school and suffer from many kinds of diseases.

    The United Nations (UN) tries to guess population growth. At the beginning of the 21st century, the world's population was around six billion people. The UN has said that the world's population will level off at 12. 5 billion people by the year 2100. Other people think the world's population will continue to grow, reaching 14 billion people before it becomes stable or even falls.

How to be a friend of yourself?

We often pay attention to developing relationships with others. However, we forget the basic step: being friends of ourselves. How can we have good relationships with others if we don't even have good relationships with ourselves?{#blank#}1{#/blank#}.

First, forgive(原谅) yourself. It's true that you are not perfect, and neither is everybody else. It's normal for everyone to make mistakes.{#blank#}2{#/blank#}.

Second, accept things you can't change. There are many things you cannot change, such as your background and past.{#blank#}3{#/blank#}If you face the things you can't change, just smile and move on.

Third, focus on(聚焦于) your achievements. You can try making a list of your achievements, which do not have to be big things. There are a lot of small but important achievements in our life.{#blank#}4{#/blank#}

Last but not least, stop comparing yourself with others. You are unique.{#blank#}5{#/blank#} Your success is not determined(决定) by other people. Instead, it is determined by your own life purpose.
