Experts recently suggested that teens should start adopting early bedtimes. Before you dismiss it as a habit suited only for young kids, consider that there are serious advantages in being well-rested. And now, even more research suggests that putting phones away before going to sleep is important to teens’ well-being.
A new study from Seton Hall University School of Health and Medicine Science found that 62 percent of kids used their smart phones before bed, and it’s causing less sleep and poor performance in school.
Those teens who text(发短信) before bedtime tend to go to sleep later, and get up later in the morning. Such behavior can be associated with mental health issues like depression or anxiety. Besides, once teens do receive a text, experts found, they tend to respond right away. Then the text conversation continues — resulting in an even later bedtime.
The study’s co-author Dr. Peter Polos says this leads to excessive stimulation(过度刺激) at night. Light from electronic devices can block the secretion(分泌) of melatonin — a hormone(荷尔蒙) that promotes sleep, which makes sleep difficult in the face of overuse of smart phones at night. It’s true! More screen time means less sleep time; other studies have suggested the same idea.
As for a final piece of advice, Dr. Sushanth Bhat says, since getting the proper amount of sleep is very important for brain development and learning in the teenage years, our study should encourage parents and guardians (监护人) to limit adolescent smart phone usage at night. Keep in mind that teens aren’t the only ones addicted to their phones! Adults can also benefit from setting a tech curfew(宵禁) for themselves. After all, kids learn by example!
1.What is the text mainly about?

American government suggests that children and teens should get 60 minutes of physical activity every day. But less than half of children and just 10% of teens meet these suggestions. What’s the deal?
It’s reported that about 44million US kids participate in organized sports(such as baseball, softball, soccer).But a new study says just one-quarter of kids get the government-recommended amount of exercise when they show up for team practices. The study, published online last month in a medical journal, says younger kids and boys do better than teens and girls.
The study looked at 200 kids aged 7 to 14 who played on soccer, baseball and softball teams. The kids wore sensors to measure their activity during practices.
During each practice, kids averaged 30 minutes of downtime(停工期). “It is not clear how much physical activity is provided by youth sports practices,” say the California-based authors of the study. “Much of the time may be inactive, such as receiving verbal instructions and waiting for turns.”
What’s a parent or coach—or kid—to do? The authors of the study suggest increasing the number of practices, extending the time of practices and changing it up(加快)during practices. For example, the coach could give each player a ball at the same time. Rather than focusing on one player’s skills, it’s best to get the whole team moving.
But, the study says, the bottom line is that team sports aren’t enough exercise. For a child to meet the US physical activity suggestions, the kid will have to do more than just join a team. Exercise is also necessary during breaks, during physical education class, after school and even on the way to school.
1.According to the text, which of the following statements is TRUE?
A. Only 10% of the teens can’t meet the suggestions about physical activity.
B. About 11 million US kids can get enough amount of exercise in team practices.
C. The new study was published on a famous magazine last month.
D. Teens do better than girls and younger kids in the new study.
2.The underlined word “extending” in Paragraph 5 means .
A. giving support or confidence
B. becoming smaller or fewer
C. making something longer or larger
D. causing to move or go quickly
3.The passage is probably written for .
A. physical teachers and parents
B. doctors and nurses
C. class advisers and researchers
D. kids and headmasters
4.What’s the best title of the passage?
A. Necessary for Kids to Exercise
B. Kids for Fun?
C. How to Keep Fit
D. Not Enough Exercise?

Experts have recently found that making conversation plays an essential part in connecting with people and building closer relationships. Although most people can hold a conversation, only a few are smooth when they talk. If you have dreamed about being a good talker, or you just want to make some change, then listen up!
●Talk slowly
Generally, good talkers don’t rush into a conversation. 1. They act as if they have all the time in the world. This makes them come off as centered and collected. Model this way of talking and you will create the same effect.
●Hold more eye contact
Most people keep eye contact about 2/3 of the time or less when they talk. 2. This will convey confidence and interest in interacting with them.
3.
People with good conversation skills are more likely to notice the kind of things that the average person doesn’t notice, and to bring such details into the conversation. They may notice and point out an interesting ring on the other person’s hand, a certain foreign accent, or a certain voice tone they use when saying a name. All these details help to leave a deep impression.
●Express Your emotions
4. Express your feelings about those facts. Keep in mind that it is at the emotional (情感) level that people connect best.
●Use the best words
The ability to talk smoothly has a lot to do with choosing the precise(精确的) words to convey your precise feelings or thoughts. 5. It will help you develop a way with words and allow you to express yourself more easily.
Conversational skills don’t improve just like that. It takes time, practice and the ability to learn at a rapid rate from your own experiences.
A. Notice the details.
B. Offer interesting news.
C. Improve conversational skills.
D. Don’t just present the facts—you’re not a newspaper.
E. It’s a very good idea to hold eye contact just a bit more than that.
F. Develop your vocabulary and practice communicating as accurately as possible.
G. They take their time when they think over something and when they say it out loud.
