Sam Scott and his sister are both students. They1to school every day. Some students often take a bus to school. They sometimes play2after school. They do3homework before dinner. They watch TV4about an hour. They go to bed5 It's a good habit.

   In thetime it takes you to read this sentence, the population of the Earth will have grownby 10 people. That may not sound much, but it is about 14,000 people an hour. Thatis 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 countriesare found in much of Africa, South America, and parts of Asia. In the developedcountries of Europe and North America, the population is growing very slowly. Thisis 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, aroundone 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 belowthe 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 beginningof the 21st century, the world's population was around six billion people. The UNhas said that the world's population will level off at 12. 5 billion people by theyear 2100. Other people think the world's population will continue to grow, reaching14 billion people before it becomes stable or even falls.

At 9:30, Rose said, "I hate going to bed. I want to stay up and watch a show!" At 6:00 in the morning, her alarm clock went off. Her mother heard her say, "The only thing I hate more than going to bed is getting up in the morning!"

What does Rose have in common with thousands of kids? She is not getting enough sleep. Have you ever stayed up later than you should? If you have, you know that not getting enough sleep can leave you feeling tired and upset. You may have even noticed that it's hard to think clearly and stay focused (专注的) when you are overtired.

Need some motivation (动机) to go to bed on time? Here are some important advantages (好处) of getting a good night's sleep. After a good night's sleep, we are more energetic, smarter and even happier.

Do you like to play sports? It has been shown that football players, swimmers and tennis players all perform better after a good night's sleep. Your coach may not tell you this, but the simplest way to improve your performance is to get enough rest.

Do you want to improve your grade? Healthy sleep habits improve your memory and your ability to pay attention to tasks, making schoolwork seem easier. While you get a snooze, your mind is very busy so you needn't get a good rest like a long sleep. Researchers have found that it's easier to learn after a good night's rest. So, it's no surprise that students who get enough sleep get better grades than those who don't.

Science and experience have shown that getting a good night's sleep is the key to success in whatever you do. Get a good night's sleep. You're worth it.

The Internet has changed our habits, including our habits of sending greeting cards. There are many e-card websites that make it so easy to find the right greeting cards. They have greatly changed the way we send greetings to each other.

Our lives have become so busy that we have limited personal time. These e-card websites have allowed everyone to e{#blank#}1{#/blank#} share their feelings and emotions with the people they love. They contain plenty of greeting cards that can be used immediately. The users can choose any card they like, from festival greetings to birthday w{#blank#}2{#/blank#}. In fact, e-cards are perfect for any event. That's why more and more people like to send e-cards. If the users are i{#blank#}3{#/blank#} in making their own greeting cards on the Internet, they can create a card within only a few minutes.

A{#blank#}4{#/blank#} benefit of e-card websites is that they have made it possible for you to send top quality cards to your beloved ones and surprise them with cheerful greetings. They allow you to send your greetings on a specific date. So you can plan for the occasion when you want to send the card. For example, you can send your e-card on a certain day and then visit the person with some flowers the next day. This will surely create a good impression o{#blank#}5{#/blank#} the person you love.

We have never forgotten the importance of saying sorry to our beloved ones. But sometimes we fail to do b{#blank#}6{#/blank#} we are not brave enough to face those we hurt. Some e-cards on these websites allow us to express our feelings in a more thoughtful way.

Although some people still would rather buy t{#blank#}7{#/blank#} cards in the shops for the persons they love, especially when they want the cards to last a long time, more and more people are choosing to send greetings on the Internet.

Parents often find children watch cartoons for at least three to four hours a day. Studies show that kids start watching cartoons on TV at an early age of six months, and by the time they reach the age of two or three, they become fans of cartoons and they would like to spend much time on them. Is it good for kids to watch cartoons?

Parents often see this as a problem because most of the kids are too crazy about watching cartoons. Parents think if kids spend too much time on cartoons, they won't do well at school. 

Some people think it's good to watch cartoons. They help the working parents the most because parents can do a lot of work when their kids watch cartoons on TV. 

When children watch educational cartoons, they get to learn things. Cartoons also help to improve children's language skills. Educational cartoons help children try different languages. Kids can learn English well with the help of those cartoon programs. At the same time, some kids can learn about the friendship and teamwork from the cartoons. It is good for them to get on well with their friends and classmates. 

So sometimes it is meaningless to stop kids from watching cartoons, but parents should make sure that their kids are watching the right things.
