Everybody knows how important it is for students to get a good night's sleep every night. You aren't able to do your best and keep up with all of your responsibilities unless you sleep well. I'm sure you already know that you should go to bed at a reasonable hour. Most experts agree that the ideal number of hours is eight, and his has been accepted as common sense for as long as I can remember. However, I was young once and I know that most of you get much less sleep than that—and in some cases it will be affecting your schoolwork.
I read an interesting article in a teachers' magazine recently. they did a study of 848 students in Wales. Worryingly, the results showed that teenagers are facing a new problem. They may go to bed get up at suitable times but a growing number are waking up in the middle of the night, not to use bathroom or have a snack but because of a new phenomenon: FOMO-fear of missing out!
According to the article, schoolchildren are suffering because of a growing trend(趋势)to wake up during the night to check social media. Afraid of missing a comment or opportunity to take part in a chat teenagers are waking at all times of the night, going online and getting involved. All this happens when they should be sound asleep.
Experts are worried about this growing trend and the report gives some worrying results that I'd like to share with you: 23% of 12 to 15-year-olds wake up nearly every night to use social media. Another 15% wake up at night once a week for the same reason. One in three students are often tired and unable to behave energetically in the daytime. Students who use social media during the night are more likely to suffer from depression and anxiety.
So, I'd like to ask you to be responsible when it comes to social media. Be brave! Switch off your devices at night. The world won't end and your social media will be waiting to greet you in the morning! I give you my word that you won't have missed anything important.

What is the most important invention of all time? Is it the written word that helps us to record information? Is it the telephone that lets us talk to people from all over the world? Is it the car that lets us travel at great speeds to meet others? Umberto Eco, an Italian writer, thinks it is something quite different. He says the most important invention might be bright in front of your eyes. He is talking about a simple pair of glasses.
Modern eye glasses were invented around 1000 years ago. They were more than just a convenient way to read. Before glasses, writers, scientists or teachers who could not see properly had to memorize everything. After about ten years of poor eyesight, they could not remember well enough and could not work. Glasses meant that people could work in their old age.
People who wanted to remember some information could write it down and read it. Eye glasses are one of the world’s greatest inventions and were probably worn by the people who designed the first telephones and cars.

Should we teenagers help our parents do chores? Is it important for us to learn how to do chores? I think so. Most of the teenagers like us students are the only children in each family. So our parents love us very much. They have done everything well for us and don’t want us to do any chores. I think it’s bad for us. It's not the true "love" we want to see.
I have a classmate called Li Ting. She is the only child in her family like me. Her parents love her very much, and they don’t let her do any chores. Every day she only gets up, has meals, goes to school, comes home, does homework and goes to bed. So she doesn’t know how to do chores. One day, her father was badly ill and had an operation in a hospital. Her mother had to take care of her father in the hospital and couldn’t cook the dishes for Li Ting for a week. Li Ting didn’t know how to cook the meal. She fell down in great trouble and often felt hungry. She even had instant noodles for meals. How funny! From the story we know it’s very important for us to learn to do chores and learn other skills from now on besides studying.
根据文章内容,判断句子正(T)、误(F)
1.Parents usually do everything for children at home.
2.Not all the teenagers are the only children in each family.
3.Li Ting can do some chores at home.
4.Li Ting's father was badly ill just for one day.
