Sammie Vance,14，knows there’s nothing worse than feeling left out.For years，she’s been helping kids who feel lonely make friends.What she was doing was running the Buddy Bench program.The idea was that anyone at school who was feeling lonely could sit on the “buddy bench”．That let other kids know someone needed a friend.“It’s really helpful to have other people be able to notice you，” Sammie says.
The idea quickly caught on.The bench brought kids together.Since then，Sammie has helped communities all over the country set up buddy benches.“It means a lot to me，” she says，“that this is making a difference in people’s lives.”
Sammie got the idea for the Buddy Bench program at summer camp in 2017.She thought it would be cool to have a buddy bench in her school，so when she got home，she presented the idea to her principal，her teachers，and her parents.
Getting approval for the project was just the first step.“There have been a lot of small challenges，like money，” Sammie says.
To reduce costs and be eco-friendly，Sammie decided to make the bench out of recycled material.So she called on her community to gather bottle caps.
Word of the project got out，and soon Sammie was getting caps from people in all 50 states.She even got them from people in Germany，the Netherlands，and other countries.In the end，she collected more than 1,200 pounds of bottle caps.A company called GreenTree Plastics was able to upcycle these into three benches.
In addition to all the kids her project has helped，Sammie is grateful for how it has changed her.“It just helped me grow in so many different aspects of my life，” she says.
Before long，Sammie was helping other schools acquire benches.She has donated more than 200 benches to schools and parks all around the country，and in Mexico and Australia.Her work continues to spread kindness far and wide.
Even small acts of kindness can be powerful.“It can make someone’s day and lead to a chain reaction，” she says.“You never know.Just be kind，in general.”

Teenagers need eight to ten hours of sleep per night.However，in adolescence(青春期) changes to the body’s sleep cycle make it difficult for teens to fall asleep early.Many cannot fall asleep until 10：30 p．m.or even later and most of them will feel sleepy if they have to get up too early.
Scientists recommend that both middle and high schools begin no earlier than 8：30 a．m.Later school start times support the natural needs of teenagers and increase their sleeping time.
Here are some other benefits of later school start times：
More time for a healthy breakfast
When running late in the mornings，students are likely to go without breakfast.With an empty stomach，one finds it difficult to focus in class.When they are always in a hurry，students may form unhealthy eating habits.
With extra time before going to school，students can eat a well-balanced breakfast and focus more on learning.
Fewer behavioral problems
Teens experience mood changes as a common result of this special period of life.Less sleep may cause worries，stress and unhappiness.
When they get enough sleep，students are calm and peaceful and their moods do not change suddenly.They’re less likely to feel worried，unhappy or get angry.For parents，children with more sleep are easier to live with.
Better performance(表现) in study
Sleep loss hurts attention，memory and brain development.Students with less sleep have difficulty paying attention in class and are likely to have lower grades.Students with enough sleep can be more energetic during the day and more willing to learn.They are also less likely to fall asleep in class and more able to understand what they learn.
In conclusion，starting school later helps students get a better night’s sleep.It improves their chances of eating，behaving and performing better.
5．According to the passage，what may cause teenagers to stay up

American students have different types of school transport.They usually take a yellow school bus or walk to school if they live close enough. 4 When they turn 16 years of age，most take a free driving class at school for one term.If students earn passing grades in the class and also pass their state driver’s exam，they can begin driving themselves to school.
5 They must take science，math，English and social studies.They can choose art，homemaking，fashion design and other classes.In some schools students are required to take one or more of the following special classes：health education，physical education or foreign language studies.Students move to different classrooms for each subject.This is because each teacher has their own classroom.There is a five-minute break between classes，to give the students the time to hurry to their next class.
The regular school day usually ends early in the afternoon.After school more than half of the students are involved in after-school activities.These activities include sports—especially football，basketball，baseball and soccer or clubs，such as yearbook，speech，school newspaper，photograph or student government.
