Someday you may no longer need to brush your teeth by hand.Instead,billions of
nanoparticles(coul automatically do all that work for you.The nanoparticles are very tiny.
Magnets(can make them move.If you set up a magnet in just the right way,says Ed Steager,"You
can arrange them into any shape you want."
Steager is an engeer at the University of Pennsylvania.Together,he and hiscollague Hyun Koo
found a way to form the nanoparticles into long.skinny bristles(),a lot like the ones on a
toothbrush.But these bristles shape-shift to fit whatever surface they encounter.They can even squeeze
between teeth.
The scientists tested the robotic bristles in the lab.But the device isnt yet ready for people to use.
The magnets and nanoparticles will need to fit comfortably and safely inside a person's mouth.The
researchers are working with a company to accomplish this safely and effectively.But if these inventors
can perfect the device,a lot of people will benefit,especially the disabled.
The tooth-cleaning robot works thanks to two magnets.One goes on each side of the teeth.The
nanoparticles sit in a water-based solution between the magnets.All of this may fit into something the
size and shape of a mouthguard,though the researchers havent settled on a design for the device yet.
As a bonus,the nanoparticles also kill those harmful bacteria in the mouth.The water-based liquid
that holds them contains a substance commonly added to toothpaste()and mouthwash.It kills some
bacteria on its own.But when these nanoparticles react with it,powerful germ-killing substances get
created.
The new device is just a proof of a notion.The researchers still need to turn it into a product that
people will want to use.It must fit comfortably and safely in people's mouths.It can't draw too much
power or cost too much."There's a lot of engineering to get from here to there,"says Steager.But,as
Melo says,"every good idea needs to have a start."

Being a person of value
What Einstein said means aiming to be a person of value rather than merely succeeding. I see it as urging us to rethink what matters most. As a high school student, success often links to grades and popularity. But what if we aim for more—a life of value？
Last year, I participated in a food drive for the local shelter. Instead of merely donating canned goods, I volunteered at the shelter. I met people who had lost everything. Their stories touched me deeply. I realized that my time and presence mattered more than any test score. What truly counts is the value we bring to others.

She realized that this might be her only chance to pursue her passion. At the thought of that, she decided to talk to her mother. "Mum, I promise I'll still help around the house and do my chores, but this is a once-in-a-lifetime opportunity for me." Mrs. Muntari looked at Mavis, considering her request. She could see the determination in her daughter's eyes. " Alright, Mavis. I'll support you. ”
Paragraph 2:Everything seemed to change after her parents witnessed her performance in the field .They realized how talented Mavis truly was and began to support her dream. With their encouragement, Mavis's confidence soared. She started training harder, and her skills continued to improve. One day, while playing a local game, a scout was in the audience. Mavis's outstanding performance caught the scout's attention, and soon, she was offered an opportunity to play for a professional team in England. She proved that with hard work, talent, and a strong belief in oneself, anyone could achieve their goals and make a difference in the world.

【原文】M: We’ve just moved into a new house.
W: Really Congratulations!
M: Thank you, so we want to buy a new TV set.
W: What kind of TV set do you want to buy
M: Maybe we should buy a big one. What’s your opinion
W: In my opinion, I don’t think it’s necessary to buy a very big one. Your sitting room isn’t very big. If you put a very big television in the room, it will be bad for your eyes, and a small TV set can still pick up good programs.
M: Mm, that’s quite sure. The big one is not the better choice.

听第10段材料，回答第17至20题。
【原文】
M: Hello, everybody. I’m Reid. Today I will discuss the effect of sleep on school students. Many teenagers are getting little sleep and there are concerns that this could have a serious long-term effect on their body health and spirits, but we aren’t sure about that now. However, one study has clearly shown that high school students getting low grades also get on average one hour less sleep than students getting high grades. Then why aren’t teenagers getting enough sleep I think they spend too much time on TV and computer games. So how can teenagers fall asleep easier Well, don’t have any soft drinks or any drink that contain chocolate before sleeping. Reading a book or listening to a story, rather than music, should help your brain relax.
It would be better for schools to stay open longer so that pupils can do homework before they get home. Another thing that some schools have tried successfully is to begin the school day half an hour later and end the school day half an hour later, and I really recommend that.
