We are lucky to live in a world that is full of incredible technology. Our living rooms are packed with computers, LCD TVs, video game systems, and Blue-ray players that help us enjoy the latest entertainment. Although these items bring us joy and convenience, they also create a lot of junk. Each device needs its own plug and adaptor to keep its batteries recharged, and over time these wires get tangled (缠绕在一起的). Thankfully, something has come along to help rid our homes of this mess while still supplying these devices with the power they need. It’s called wireless charging and this trend is just starting.
Wireless charging has a lot of potential for smartphones and other electronic devices. Electronic devices can absorb the electricity once they’re placed on a special charging mat. There are several advantages that wireless charging offers over traditional methods. For starters, cords (电线) have a tendency to wear out with use. Wireless charging users never have to worry about buying replacement cords. Wireless charging is also far more convenient for medical implants, as patients won’t need to recharge their devices through the skin using cords. In turn, this cuts down on the risks of infection. Wireless charging can also bring safety benefits, as wired charging devices that come in contact with water can increase the chances of getting an electric shock. Wireless charging gets rid of that danger completely.
Still, there are a few drawbacks to wireless charging. The first is speed. It takes a bit longer to charge devices wirelessly than it does if the device is plugged in. The process also requires more heat, so devices tend to get a bit hotter, which could create other safety issues. Also, since devices must be left on a special pad while charging, it is harder to operate them while they are powering up. This limitation may be gotten rid of in the future, as researchers are developing transmitters (发射器) that can charge several different devices in a room without the need to connect to a charging pad. Although wireless-charging technology may be far from perfect, it seems like a step in the right direction as we move towards a less-tangled future.

Foreign visitors to the UK might be disappointed when they learn that not everyone there speaks like Harry Potter and his friends. Usually, there’s an assumption by many non-Brits that everyone in Britain speaks with what’s known as a Received Pronunciation (RP, 标准发音) accent, also called “the Queen’s English”. However, while many people do talk this way, most Britons speak in their own regional accents.
Scouse, Glaswegian and Black Country – from Liverpool, Glasgow and the West Midlands – are just three of the countless non-RP accents that British people speak with. There are even differences in accents between towns or cities just 30 kilometers apart. What is even more disappointing is that not speaking in a RP accent may mean a British person is judged and even treated differently in their everyday life.
In a 2015 study by The University of South Wales, videos of people reading a passage in three different UK accents were shown to a second group of people. The group then rated how intelligent they thought the readers sounded. The lowest-rated accent was Brummie, native to people from Birmingham, a city whose accent is considered working class.
However, there is no need to be disappointed though you are not speaking in an RP accent. In fact, doing the opposite may even give you strength.
Kong Seong-jae, 25, is an internet celebrity from Seoul. After studying in the UK, he picked up several regional accents. He’s now famous for his online videos, where he shows off the various accents he’s learned. “British people usually get really excited when I use some of their local dialect words, and they become much friendlier. I think it makes a bit of bond between local people and foreigners to speak in their local accent,” he said.
So if you’re working on perfecting your British accent, try to speak like someone from Liverpool, Glasgow or Birmingham. You may not sound like Harry Potter, but you are likely to make more friends.
1.What can we infer from paragraph 1?
A. Only “the queen’s English” is accepted in the UK.

When school started on that warm August day, I threw myself into everything I did, including playing volleyball. I decided to become beautiful, or at the very least, skinny. I stopped eating completely. Soon I began losing weight, which thrilled me, and I even grew to love the tiredness and lightheadedness that came with my poor diet, for those feelings meant that I was winning.
As the season progressed, things had become tense between my head volleyball coach, Coach Smith, and me. She felt that something was wrong with my health. She talked with me about my eating and was angry that I wouldn’t listen to her when she tried to make me eat. She tried to persuade me in a determined way and so we fought constantly. Then my hunger started to affect my performance. I was so tired that practice and games were becoming a struggle. One afternoon, with hurt in her eyes, Coach Smith asked me what I had eaten and I told her nothing yet, but I was going to. She looked at me, disappointment in her eyes, knowing she couldn’t make me stop, and walked away.
A couple of weeks later I attended a formal dinner for our volleyball team. I stood there as my coach managed to say something nice about me. I realized then that I had ruined my senior year by being disrespectful, and I had probably ruined hers as well. So that evening I wrote her a letter apologizing and thanking her.
Then one Saturday, as I was reading in the library, I felt someone gently take my arm and say softly, “Lynn Jones, how are you doing?” I looked up and saw the familiar face. “Thanks for the letter,” she said. “It meant a lot.”
When I think of a coach, I think of someone above me, someone who gives instruction—not a friend. But Coach Smith is different, and, like any other good friend, she dealt with my problem in a determined way even when I hated her for it at that time. I didn’t deserve her kindness, but she gave it anyway. I will forever be grateful for her help, and now for her friendship.

Last week, Donna Strickland was awarded the 2018 Nobel prize for physics jointly with Arthur Ashkin and Gérard Mourou. It’s the first time in 55 years that a woman has won this famous prize, but why has it taken so long? We look at five other pioneering female physicists — past and present — who actually deserve the prize.
Jocelyn Bell Burnell
Perhaps the most famous snub(冷落): then-student Bell discovered the first radio pulsars in 1967, when she was a PhD student at Cambridge. The Nobel prize that recognised this landmark discovery in 1974, however, went to her male supervisor, Antony Hewish. Recently awarded a £2.3m Breakthrough Prize, which she gave away to help under-represented students, she joked to the Guardian: “I feel I’ve done very well out of not getting a Nobel prize.”
Lene Hau
Hau is best known for leading the research team at Harvard University in 1999 that managed to slow a beam of light, before managing to stop it completely in 2001. Often topping Nobel prize prediction lists, could 2019 be Hau’s year?
Vera Rubin
Rubin discovered dark matter in the 1980s, opening up a new field of astronomy. She died in 2016, without recognition from the committee.
Chien-Shiung Wu
Wu’s “Wu experiment” helped disprove the “law of conservation of parity”. Her experimental work was helpful but never honoured, and instead, her male colleagues won the 1957 Nobel prize for their theoretical work behind the study.
Lise Meitner
Meitner led groundbreaking work on the discovery of nuclear fission. However, the discovery was acknowledged by the 1944 Nobel prize for chemistry, which was won by her male co-lead, Otto Hahn.
1.When was the discovery of radio pulsars recognized by the Nobel?
A. In 1944. B. In 1967. C. In 1974. D. In 1980.
2.Which woman is most likely to win a Nobel prize later according to the text?
A. Donna Strickland. B. Jocelyn Bell Burnell. C. Lene Hau. D. Vera Rubin.
3.What do we know about the five females?
A. The five female scientists did greatly in chemistry.
B. Vera Rubin had opened up a new field in geometry.
C. Lise Meitner’s teacher won a Noble prize for her work.
D. All their findings haven’t been recognized by the Nobel.
