2 . If you’ve ever had trouble getting your teen up in the morning or you’ve seen your teen fall asleep during the school day, you’re not alone. Many teens have difficulty in waking up early for school, and that’s because they sleep late at night.

The American Academy of Pediatrics’ Adolescent Sleep Working Group reviewed studies about sleep in teens. Researchers studied the harmful effects of not getting enough sleep-anything less than 8.5 to 9 hours of sleep on school nights-could have on young people. They discovered not getting enough sleep may cause poor grades at school. Not getting enough sleep has also been connected to a higher risk of car accidents in teens.

It may seem as though the way to solve the problem would be for teens to just go to sleep earlier. But researchers say that isn’t likely to work. Teens experience physical changes that make falling asleep earlier difficult. Their biological (生物的) clocks just won't allow them to fall asleep at 8 p.m., even when they’re tired.

Studies have shown that just delaying (推迟) school by 30 minutes can have a great effect on a teen's health and performance. So most researchers suggest the school start time be delayed until at least 8:30 a.m. for teenagers.

Some of the benefits could include:

·Teens may be more likely to get the necessary amount of sleep.

·The delayed start time could help teens sleep during their natural sleep.

·Teens may be less likely to depend on coffee to stay awake during the day.

·Enough sleep could help teens study better in class, which could help them do better in exams.

·Sleeping longer could reduce health problems caused by a lack of sleep in the long run.

·Getting home later in the afternoon may reduce the amount of time when some teens are home alone, and could reduce the possibility that tens will take part in unhealthy activities.

But doing that can also cause some problems.

7 . The newest Japanese robot has a name and humanoid look. It is 1.70 meters high and can easily walk on a slippery floor. Not only is it able to operate a tool by its right hand, leaning forward and bow, but also it can balance it as a human does. The robot can not take over some human professions, such as low-tech construction workers, dustman and guards as well. It had the ability to perform human functions. The entire production cost will be reduced and the problem what Japan is rapidly aging and need a larger work force urgently can be solved.

8 . My favourite book is The Adventure of Tom Sawyer by Mark Twain. Tom lives with his aunt Polly in a quiet street of St. Petersburg, Missouri. He’s a lively and clever young boy, and he finds himself in many exciting adventures. He runs away with his two friends, Huck Finn and Joe, to an island in the middle of the Mississippi River for several days. With Huck he goes looking for treasure, with Becky he gets lost in a cave. And finally, they find a box of gold.

My favourite scene in the book is when everyone thinks Tom is dead. He decides to go to his own funeral. He hides and watches for a time and then suddenly he appears. Everyone is astonished to see him but they’re also pleased to see him alive.

Tom is the hero of the story, but there are other important characters. Huck is an outsider and everyone is afraid of him. Becky is pretty with fair hair, Joe is Tom’s best friend. And Injun Joe is the bad man of the story.

The theme of the story is about children growing up. It describes how strangers are seen in small towns of America. Finally, it talks about freedom, social rules and how people are punished for bad behaviour.

Why do I think The Adventure of Tom Sawyer is a great book? Mark Twain wrote the story in 1876, but it’s still read and loved by people all over the world today. And although it’s only a story, Twain wrote it in the everyday English of the southern states of America in the 19th century, so it sounds very real. Today it’s thought to be one of the greatest books in American literature. Go on—read it! I know you’ll enjoy it, too.

9 . LANGUAGES Canada,a new Canadian national organization of public and private language training programs,was started recently to ensure that language training in Canada is of high quality,Canada News Wire has reported.
