A little battery puts out a little bit of electricity, so you can use it safely for your experiments. But the electricity that comes through the wires in your house or school is much more powerful.1..
Inside the walls where you live or study, there are big wires that carry electricity. When you plug in a light or radio or other electrical appliance, you are putting the light or radio in the path way of the electricity. You have heard adults say, “Don’t stick your finger into the wall plug.” Now do you know why?2.Your body is a pretty good conductor of electricity. The electrical current coming through the wires to the wall plug is so strong that it would hurt a lot if you stuck your finger in the plug.
Think: Why should you never put your fingers into the socket（插座）where the light bulb is fixed into a lamp？3.Put your finger in there and it could be you, rather than the light bulb, that becomes part of the electrical path way. And that would hurt！
What if you held a piece of metal, like a fork or knife, and stuck it into the wall plug？Don’t do it！Why？It’s because metals conduct electricity. And you would get a terrible shock！
4.Can you think why？It’s because water is a good conductor of electricity. When your hands are wet or when your body is in a bathtub full of water, the electricity could flow right through you and give you an awful shock, or even kill you.
Electricity is very useful, but it can be dangerous. Be careful, be safe and be smart.5..
A.Let electricity help you, not hurt you.
B.Keep yourself away from the electricity.
C.Therefore, you need to remember some safety rules.
D.Don’t touch any electrical appliance when you are wet.
E.Make your home as safe as possible for kids with these tips.
F.If you did, you would become part of the electrical path way.
G.That’s the place where the electricity flows into the light bulb.
A desire among many seniors is to “age in place.” Aging in place is a term used to describe a person living in their own house, for as long as they are able to, as they age. Yes, the familiarity of your current home is the advantage of aging in place, but the potential financial drawbacks to renovate（翻新）the house might actually be more costly than the long-term benefits.
40 years ago, with a growing family, you probably purchased a 4-bedroom child-friendly house. Now, with kids moving out, you might be thinking about changing one of your bedrooms into a massive master bathroom, and another into an open-space reading area. You might also be thinking about cutting back on lawn maintenance（草坪维护）by installing a pool surrounded by beautiful paving stones. It all sounds wonderful doesn’t it？For the short term, you may really enjoy the new upgrades, but you’ll still have to climb those stairs, pay to heat and cool a home that’s larger than what you need, and continue fixing all the things that start to go wrong with a 40-year-old home.
Last month, in their Retirement Repot, Kiplinger addressed the point, “Renovations are just a part of what you need to make aging in place work for you. While it’s typically less expensive to remain in your home than to pay for assisted living, that doesn’t mean it’s a slam dunk to stay put. You’ll still have a long to-do list. You need to plan ahead for how you will manage maintenance and care-for your home, and for yourself.”
So, at some point, the time may come when you decide to sell this house anyway. That can pose a big challenge if you’ve already taken cash value out of your home and used it to do the type of renovation we mentioned above. The family moving into your neighborhood is probably similar to what your family was 40 years ago.

Noah Higgs hated learning Irish in school. He hated the way it was taught, overly formal and disconnected from ordinary people’s lives. Most of all he hated the effect the lessons had on his fellow students’ willingness to speak the language. But the Dublin native never lost his love for Irish, nor his opinion that more people should be learning the language.
Today, almost 40% of the 7,000 languages spoken worldwide are endangered, according to the United Nations. More are going extinct every year. It was once widely feared that the Internet revolution would accelerate this decline. If developers and smartphone manufacturers aren’t willing to invest in supporting minority languages, that would cut off people who speak them from an important way to communicate and trap those languages in the past.
Higgs, 23, though, is one of a small group of educators and activists reinventing how minority languages are taught and preserved online by using cutting-edge technology.
When he was 17, Higgs had a “crazy teenage idea”. He had begun using Duolingo, a mobile language-learning app, to study French, and wondered if the creators had considered adding support for Irish.
At the time in early 2013, there were five languages on Duolingo, the smallest of which, Italian, has an estimated 67.9 million speakers worldwide. By comparison, at its height in the 18th century, there were an estimated four million Irish speakers. Today the figure is closer to 1.2 million.
“I didn’t get a reply,” Higgs said.
But his email wasn’t ignored. Inside Duolingo’s open-plan, Silicon Valley-style headquarters in Pittsburgh, Pennsylvania, change was going on. Within five years, the language startup would build a library of over 30 languages, including some of the most endangered on the planet.
1.What was the public concern over the Internet revolution?
A.People’s less contact in real life. B.The negative effect on the lessons.
C.Fewer ways of learning languages. D.The decline of endangered languages.
2.What was Higgs’ “crazy teenage idea”?
A.Turning to Duolingo to study French.
B.Teaching minority languages on the Internet.
C.Asking Duolingo developers to support Irish.
D.Using cutting-edge technology to preserve Irish.
3.What can be learned from the last three paragraphs?
A.Higgs’ email went unnoticed. B.Duolingo improved its service.
C.Duolingo’s headquarters changed. D.Irish was on the point of dying out.
The promise of college in America is the promise of a clear path to the future, of a reward for all the sleep deprivation and soul-deadening competition of high school, and, most of all, of instant adulthood. As of April, 2020, however, none of that is happening due to the outbreak of the novel coronavirus（新型冠状病毒）.
Saminah Haddad, a seventeen-year-old senior at Long Beach Polytechnic High School, wasn’t expecting her college offers until later in the spring. This year, there will be no spring season, which for Haddad means no four-year college. She is considering Long Beach City College, which is free for state residents. She also lost her job at an amusement park. All of the senior-year milestones that Haddad had been looking forward to have been cancelled: prom, graduation, and an event called the “Pursuit of Excellence Awards,” where she would have been recognized for perfect attendance. She doesn’t yet know if she’ll still be working this summer for her father, who was about to open a juice bar in Brooklyn.
In the meantime, Haddad’s school is offering some online instruction, but in her case the course load has dropped to just two classes: A.P. Literature, which meets virtually, and a government class, which consists of written assignments that she receives by e-mail. Haddad is planning to take her A.P. exam, though she finds it hard to imagine what the forty-five-minute, cell-phone-friendly version of the test will be like. No one knows how colleges will view it, either.
Life has been emptied of content, and the plot is lost. She texts with friends. She argues with her mom and stepdad a lot. “It’s bringing us closer together,” she half joked. “But it’s O.K.”
1.What can be known about Haddad from Paragraph 2?
A.She has applied to study abroad.
B.She will attend a graduation ceremony.
C.She won’t work in her father’s juice bar.
D.She may get her college offers in late spring.
2.How does Haddad feel about the A.P. exam?
A.Doubtful. B.Bored.
C.Excited. D.Nervous.
3.In which section of a newspaper may the passage appear?
A.Family. B.Society.
C.Education . D.Health.

I was lucky enough to study abroad as an exchange student, but this allowed me to improve my language skills and found out more about the local culture. It was my active participation (参与) which helped me make the friends in a foreign country. Instead staying in my room, I got out of the house so as not to be homesick. I’ll never forget the times when I first went camping with my friends. I also tried something entire new such as a dance class and a walking club. In addition, I tried to make my voice hearing. As a result, everyone wanted to know something about myself and I made much good friends!
