While new phones are advertised as “water resistant (防水)”, this doesn't mean they are waterproof, or totally immune to water. Water resistance just implies the device can handle some exposure to water before substantial damage occurs.
The water resistance of phones is rated by an “ingress (进入) protection” code, commonly called an IP rating. The rating includes two numbers. The first demonstrates protection against solids such as dust, while the second indicates resistance to liquids, specifically water. a phone that has a rating of IP68 has a solid object protection of 6 (full protection from dust, dirt and sand) and a liquid protection of 8 (protected from immersion in water to a depth of more than one metre).
The popular iPhone 12 and Samsung Galaxy S21 phones both have a rating of IP68. However, regarding exposure to water, the iPhone 12 has a permissible immersion depth of a maximum of 6m for 30 minutes whereas the Galaxy 21's immersion limit is up to 1. 5m, also for 30 minutes.
While IP ratings indicate the water-resistant nature of phones, taking most phones for a swim will land you in deep trouble. The salt content in oceans and swimming pools can corrode (腐蚀) our device and cost you a heavy replacement.
Then how to fix a water-logged phone? Follow these steps: First, turn off the device immediately and don’t press any buttons. then wipe the phone dry with paper towels or a soft cloth and gently shake the device to remove water from the charging ports. Next, remove the SIM card and dry out the phone in front of a fan. Do not charge the phone until you are certain it's dry.
If the above steps don’t help and you're still stuck with a seemingly dead device, don't try opening the phone yourself. You're better off taking it to a professional.

【推荐2】The Best Ways to Lose Weight with Walking
Walking regularly is the easiest and least expensive form of exercise. Except for a good pair of walking shoes, no special equipment is needed. It is not necessary to join a gym.
● Ways to lose weight by walking
The first way to begin to lose weight by walking is to start walking. The initial goal should be 10,000 steps per day. Using a simple pedometer(计步器) attached to the waistband or on a belt will help you to count your daily steps. Consistency—even 10 minutes 3 times a day at first will produce the immediate results.
●
It is very important to check with your medical professional before beginning any exercise program; especially if you are over age 65, have been required sitting or little activity for more than a year,or have been diagnosed with heart disease,pregnancy,high blood pressure,or any other medical conditions.
● How to walk to lose weight
A good walking technique will help you achieve the physical or mental energy you need to walk consistently for the amount of time you have set for your goal. Making sure that you are using your large muscles correctly will also help to build your muscles.
Walking regularly can aid in muscle growth and increase the amount of calories you burn throughout the day. Eating a healthy low-fat diet will raise your metabolism(新陈代谢).
A.Limit your "bad" fat intake. |
B.Begin a walking program with suitable physical qualities. |

【推荐3】A patient and I are working on an eating disorder, trying to find out the cause. It turned out to be a relationship break-up in high school. The unpleasant experience led to not eating for a couple of weeks. Then comes a compliment (赞美) from a friend that totally has the opposite effect. “Wow, you look great!” Suddenly, this praise inspires an inner thought: “Oh, people care more about me if I lose weight. So I can control people’s affection by not eating.”
Consider busy parents who don’t notice their child until a good grade appears. In the absence of attention and connection, a sudden strong expression of well-intended praise can bring about the thought, “Wow, my grades make me valuable. I’m noticed when I achieve!” The result can be a twisted view of self-value and an anxiety around grades, exams, and performance. A similar situation occurs with athletic success or high praise for being “nice”. The result is a false mindset: “My worth is totally tied to this desirable behavior.”
So what’s a better way? One answer is to exit the game of “right and wrong” and enter a focus on what needs are present. Returning to our example above, when you see someone has lost weight and you want to give them a compliment, just pause and simply ask, “How are you doing?” See them and hear them. Appreciate them as a person of great value. There may be much more to their inner world than meets the eye.
Similarly, when you see someone’s success, appreciate the hard work they put into it. Ask with gentle curiosity, “How’s it been for you?” Listening with full attention can be a rare gift in today’s world. See if you can understand them from the bigger frame of what they’ve experienced, how they’re feeling, and what they’re needing now.
1. What can we learn from paragraph 2?A.It’s parents duty to care for their children. |
B.A strong expression of praise should be prevented. |

【推荐1】When George Smith was 31, he became enthusiastic about some ancient tablets in the British Museum. But even after the tablet fragments(碎片) had been pieced together, little had been translated. The 3, 000-year-old tablets remained as mysterious as buried in the ruins. Even so, the English archaeologist (考古学家) decided he would be the man to reveal the secrets. Smith taught himself Sumerian and literary Akkadian. After nearly two decades, Smith had a breakthrough:The complex symbols were describing a story, just like Noah’s Ark!
For thousands of years, humans have been telling stories, sharing the morally even before the invention of writing. In one way or another, much time in people’s lives is spent telling stories. Besides entertainment, stories did give us something more.
Stories can influence people’s emotional lives. Storytelling allows people to peek into someone’s conscience to see how others think and feel. Studies have found reading stories significantly increased empathy towards others, especially people initially seen as “outsiders”, such as foreigners or people of a different race. Interestingly, the more absorbed the readers are in the story, the more empathetic they are in real life. Psychologists tested this by “accidentally” dropping a handful of pens. Those who had previously reported being “highly absorbed” in the story were about twice as likely to help pick up the pens.
But why start telling stories in the first place? Their usefulness in understanding others is one reason, and another theory is that storytelling could be an evolutionary(进化的) mechanism that helped keep our ancestors alive. For example, if you heard, “There’s a monster near that tree, so don’t go over there,” it would not be as effective as told, “My cousin was eaten by a scary creature that lurks around that tree, so don’t go over there.”
Upon translating the 11th tablet, the most important part of the story, Smith told a coworker, “I am the first person to read that after 3.000 years of oblivion(被遗忘)!”
1. Why did George Smith decide to translate the tablets?A.Because he hoped to be an archaeologist. |
B.Because he wanted to learn old languages. |
C.Because he was employed by the museum. |
D.Because he showed great interest in history. |

【推荐2】Internet Explorer (IE) has finally been withdrawn from the market.
As of Wednesday, Microsoft would no longer support the once-dominant browser (浏览器) that the legion of web surfers loved to hate - and a few still claim to adore. The 27-year-old application now joins BlackBerry phones, dial-up modems and Palm Pilots in the dustbin of tech history.
IE’s exit was not a surprise. A year ago, Microsoft said that it was putting an end to Internet Explorer on June 15, 2022, pushing users to its Edge browser, which was launched in 2015. The company made clear that it was time to move on. “Not only is Microsoft Edge a faster, more secure and more modern browsing experience than Internet Explorer, but it is also able to address a key concern: compatibility (兼容) for older, legacy websites and applications,” Sean Lyndersay, general manager of Microsoft Edge Enterprise, wrote in a May 2021 blog post.
Users marked Explorer’s passing on Twitter, with some referring to it as a “bug-ridden, insecure POS” or the “top browser for installing other browsers.” For others it was a moment for 90’s memory, and The Wall Street Journal quoted a 27-year-old who was sad to see IE go. A Chinese user said that IE is nothing but corresponding with the changing tide of technology, as new things emerge in an endless stream on the Internet, and people are more likely to pursue advanced technical services, but IE’s presence could not be erased. While there are also netizens that believe that IE sitting back for another five years would not be a problem, just leave IE for those certification examinations, as some exams in China appointed IE registration website because of its compatibility.
“Welcome to Microsoft Edge from now on,” the official account of Microsoft Edge browser announced. Today, the Chrome browser dominates with roughly a 65 percent share of the worldwide browser market, followed by Apple’s Safari with 19 percent, according to internet analytics company Statcounter. IE’s heir (继承者), Edge, falls behind about 4 percent, just ahead of Firefox.

【推荐1】In his lifetime La Tour must have been one of the most admired painters, who was on close terms with courts in Lorraine and Paris and became the King’s Painter to Louis XIII in 1639. However, not many of his works survived. These can be divided into his early “day pieces”, and the later “night pieces”. His sometimes direct realism and unflattering (不恭维的) presentation of the miserable subjects does not at all mean a sympathetic attitude to the socially disadvantaged of the day, on the contrary, issues of this kind were intended to amuse high society, who enjoyed decorating the walls of their homes with such melodramatic scenes. La Tour, affected by Caravaggio, painted various scenes of gambling. In Cheater with the Ace of Diamonds, an inexperienced, wealthy and well-dressed young man is being cheated at cards in the dishonest company of a courtesan (交际花) with her lover and a servant girl. Wine and the promise of love adventure have made the young dandy (好打扮的男人) so light-headed that he does not notice the apparent trick of an ace being drawn from his opponent’s belt.
Most of the paintings by La Tour we have at our disposal the art historians date after 1640. In these works La Tour is captivated with lightning effects which create sharp outlines. This fascination with light brought him great success in his day. However, he was completely forgotten after his death, only to be rediscovered in our own day. La Tour is an example of how artists can pass in and out of favor of the public.

Li Qing, a 29-year-old resident in Fengjie, Chongqing, is an online marketer. Betting on the huge development potential of the agriculture, Li gave up her job as a white-collar worker in Beijing and moved back to her hometown to be an online marketer. She opened a store on an online sales platform, selling mushrooms, potatoes and rice.
Today, many farms in the country’s hinterland(内地)are developing fast, but they need more accessible channels to sell their products. “Over the past three years, our total sales volume has grown to more than 100 million yuan, leading to income growth for more than 1,000 rural families,” Li said. “It’s a business opportunity for me and also a good chance to help farmers earn more money.”
Jin Yi, in his 20s, is a new member of AI trainers. Just like a child learning to walk, AI needs trainers to constantly remind it of the right methods and human beings’ mindset. Through numerous data accumulation and practice, AI is able to recognize human beings’ languages.
In recent years, AI trainers have sprouted up across China as a result of the rapid development of new economic models(模式).“It’s estimated that there is a shortage of about 5 million skilled workers in the AI industry. Shanghai needs about 400,000 AI workers alone, but there are only around 40,000 students majoring in AI at colleges,” said Qiu Xin, Party Secretary of Fudan University.
“I believe our industry will see greater development in the future, along with the advancement of AI. I hope more graduates will join the industry and contribute to the development of AI,” Jin said.
In addition to creating more jobs, new technologies will help transform traditional industries, which will help create more new and higher-paying jobs in the coming years, said Li Chang’an, a professor at the Academy of China Open Economy Studies of the University of International Business and Economics.

【推荐3】New York Times---( DINITIA SMITH )Tomorrow is the 433d anniversary of Shakespeare’s birth. A recent survey shows that more people are watching him, reading him and studying him than ever before.
Consider the recent yearly conference of the Shakespeare Association of America in Washington, where more than 600 people who study or admire Shakespeare from 18 countries took in topics like ‘‘Whither Attribution Studies,’’ ‘‘Unpopular Shakespeare’’ and ‘‘Sex Me Here,’’ a talk on breast-feeding and Lady Macbeth.
‘‘The national media is saying that fewer students’ taking Shakespeare,’’ Barbara Mowat, the editor of The Shakespeare Quarterly, observed in a speech at the conference. ‘‘But Shakespeare is thriving.’’ The association’s membership has increased by a third since 1990.
The Shakespeare business is so good these days that W. W. Norton is introducing a huge new collections of the plays into the already crowdedfieldjust in time for tomorrow’s birthday anniversary. Priced at $44.95, ‘‘The Norton Shakespeare: Based on the Oxford Edition’’ runs for 3,420 pages, offering introductions, illustrations and notes and three versions(版本) of‘‘King Lear.’’
Today, movies and videos have made the plays even more accessible. Last year, ‘‘William Shakespeare’sRomeo and Juliet’’ was No. 1 at the box office when it opened, and it grossed nearly $50 million. In New York in January, crowds lined up in the freezing cold to see Kenneth Branagh’s four-hour‘‘Hamlet.’’The students select a scene and then have a violent discussion about it.’’ Influenced by films, professors are increasingly teaching students by having them perform the plays.
