Who can forget their first day of school? Students come into the classroom wondering who their teacher will be for the year.1.Introducing yourself to those students is a big part of that first day.
Pay attention to your appearance.
Dress professionally and make sure you follow any published dress codes applying to students and staff. While you want the students to enjoy their time in your class, you want them to respect you.2.On the first day, putting your best appearance forward can set the tone for the year.
Tell personal interests and hobbies.
3.It helps them identify with you as more than just a teacher. Students may be surprised you have interests after school. Explaining some of your hobbies and interests can give students the chance to interact with you on the first day. Offering these small personal details can make you seem more approachable and will open up to a connection with your students.
Explain classroom rules.
Getting started on the first day by also explaining your class rules and what your class can expect of you is a good way to set guidelines. For example, you could say “I’m easy-going, but I do have some rules that everyone must obey.”4.
5.
If you have time after your basic introduction, ask your new students if they'd like to know anything more about you. After you have answered their questions, ask the class what they have learned about you. For example, ask "What do I like to do in my free time?" By doing that, you're reiterating your introduction, which makes it easier for the students to remember you.
A. Give name details step by step.
B. Invite questions and responses.
C. Tell your class a little more about yourself.
D. Teachers are faced with new students sitting in desks.
E. Continue to remain polite and positive when speaking to students.
F. Dressing in inappropriate clothing can be destructive in the classroom.
G. Keep those rules easy-to-remember if you introduce yourself and the rules together.
Working robots, like the KASRO, are typically big, simple, and strong. They are large preprogrammed units working in dangerous and dull jobs. But the growing trend towards collaborative(合作的) robots, or cobots, is transforming robotic use worldwide.
What big companies such as Germany’s Mercedes-Benz discovered was that robots alone were not enough to keep pace with the demand for customized products. Human-robot collaboration was identified as the most suitable strategy. By shrinking robots down to desktop size and equipping them with sensors and AI, the next generation of cobots will feel our presence, learn from us, and cooperate with us better.
“When we have people and machines cooperate, we’re much more flexible and can produce many more products on one production line,” said head of production planning, Markus Schaefer. “The variety is too much to take on for the machines.”
The future of cobot working is likely to change as new ways of interacting are developed. Voice commands are bound to be a feature as natural language processing systems become more widespread. Closer integration( 融 合 ) with machine learning and AI is sure to help realize the benefits of elements such as voice control and machine vision. Unplanned changes to production and safer interaction with humans will then require a step-change in robot learning.
Cobots will learn directly from human interaction or even from simulations( 模拟) that will help them to adapt to real-world situations. Open robotics platforms, such as Carnegie Mellon University’s LoCoBot or Elephant Robotics’ Catbot, mean that programmers can share the skills they have developed via the cloud.
Importantly, for household robots to become popular, robot learning—where environmental data is gathered to make more ideal decisions— will be needed. Cobot carers, such as ElliQ the companion robot and IKEA’s robotic furniture, promise a bright future of cooperation.
Like any achievable technological dream, such as self-driving cars, their realization is coming soon. Cobots will become standard in the same way that a car’s GPS or the smartphone did. Their integration into society will gradually become normal.

A new report from the U.K. says that more than 1 in 5 teens there spend five hours or more per day on social media. And the heavier users of social media go to bed later and get poorer quality sleep. The new study was based on self-reported survey data from nearly 12,000 teenage participants in the U.K. Millennium Cohort Study.
Megan Moreno, a researcher at the University of Wisconsin-Madison, says that social media is too often described as either entirely good or bad, when the reality is more complicated for teens. "Social media may have its problems, but it is the way that they stay in touch with each other," she says.
Perhaps unsurprisingly, the study found a link between high social media usage and poor sleep patterns. Specifically, teens who report heavier social media use go to sleep later. And, the study authors note, late bedtimes are linked with poorer academic and mental health outcomes.
Holly Scott, a researcher at the University of Glasgow, isn't sounding the alarm. She says, "it's easy to look at the results of this and think, 'We should just get teenagers to spend less time on social media.' I think that's an understandable response, but what I really encourage people to do is look beyond that." She says people should pay attention to the "important emotional and cognitive and social factors" at play with when teenagers are using social media.
Scott emphasizes that the study is pointing to a correlation between social media and poor sleep, but not necessarily demonstrating cause and effect.
"Certainly some teens do say that they struggle to get off of social media at night — they might be worried about missing out on things, or affecting their friends by not answering messages — and they stay up late from that," she says. But, "maybe for some of those young people they have a naturally later body clock, and are passing their free time at night on social media until they're ready to fall asleep," she says.
1.What’s the purpose of the new study in the U.K.?
A.To find the benefits of using social media.
B.To know the effects of using social media.
C.To know teenagers’ habits of using social media.
D.To prove the growing popularity of social media.
2.What attitude does Megan Moreno take towards social media?
A.Critical.
B.Positive.

3.What does Holly Scott think of social media’s causing poor sleep?
A.It’s interesting.
B.It’s impossible.
C.It’s beyond doubt.
D.It lacks evidence.
4.What is the best title for the text?
A.How to Sleep Well Tonight
B.Social Media Is Wasting Our Time

Promise Sawyers, a 10-year-old girl in Nashville, Tenn., is inspiring people old and young after making a video before going to school “bigger and better” with her natural hair, just one day after she was made fun of for her afro.
Promise Sawyers’ motivational video was posted online by her mom Qui Daugherty, after the 5th-grader secretly recorded it on Daugherty’s phone. In it, Sawyers explained that she was feeling “some type of way” after her classmates had mean things to say after she wore her natural hair the day before. But she was determined not to let it bring her down, and wore it the same way the following day. “Don’t allow anyone to steal your joy,” Promise said. “Don’t give them that much power.”
Daugherty says that Promise has been surrounded by that type of positivity her whole life. She’s always taught her daughter to “meet a negative with a positive”, even when somebody is trying to bring her down. And although this example seems like one of the more disheartening( 令人气馁的) ones that Promise has faced after starting at a new school, her video proved that she took her mom’s advice to heart.
Now, nearly 2 million views later, people everywhere are responding to the video. “We had no idea the impact that it was going to make and the amount of messages,” Daugherty said. “It’s made a huge impact behind the scenes that has blessed me personally.”
Daugherty jokes that Promise doesn’t understand how influential her words are. Instead, the 10-year-old is just excited about the millions of views.
“I just tell her not to focus on the numbers,” Daugherty says. “Let’s find a way we can be impactful behind this and make an influence and inspire people. That’s all we want.”
1.What does the underlined word “afro” in Paragraph 1 refer to?
A.A hairstyle.

A.Switch to a new start.
B.Look on the bright side.
C.Make necessary changes.
D.Share her joy with others.
4.How did Daugherty feel about people’s response to the video?
