1 . It is sometimes jokingly said that you may skip a meal a day without any adverse effect but skip using your WeChat for an hour and you will feel distinctly unwell. It is an acknowledgement of the fact that the app is no longer only a fun tool but an essential part of life for millions.
Launched in January 2011, this messaging, social media and mobile payment app today has more than 1 billion individual users. People use it for everything, from applying for a business license to booking a hospital appointment to keeping up with family and friends, shopping and paying bills—activities that are part and parcel of our everyday life.
When it was first introduced, WeChat was only an app supporting voice, video, picture and text messages between two persons or among a group. But today it has become ubiquitous.
In the past, people carried their wallet and keys with them wherever they went; today, a smart phone with WeChat installed is all they need in daily life. Its functions like Moments and mini programs and the official WeChat accounts of government agencies and companies have made communication and public services accessible and convenient like never before.
WeChat is also widely used by enterprises. Figures from Tencent show there are around 15 million WeChat official accounts, which enjoy 5 billion followers. Most businesses use their WeChat groups as a standard marketing kit. This has immensely reduced advertising, marketing and communication costs, and in the background of the novel coronavirus disease, made operations faster, contactless and safe.
However, there are concerns about the downsides of WeChat, such as addiction among primary school children. Equally serious is the misuse of WeChat for fraud or instigating crimes. However, it has to be kept in mind that these fallouts are not really the fault of WeChat, but due to the misuse of the app.
If we learn to temper our use of messaging apps with prudence and pragmatism, we could be looking forward to yet new conveniences and experience in this decade with the rapid development of 5G technology and artificial intelligence. Ultimately, the choice is ours, whether to use WeChat or any other new invention, wisely or wantonly.

2 . Norway aims to discover new resources beneath the sea, but its push into mining has raised environmental concerms.
Norway could license companies for deep-sea mining as early as 2023. That could place it among the first countries to harvest seabed metals. Copper, zinc and other metals are in high demand for electric vehicle batteries, wind turbines and solar energy centers. However, that could also place Norway on the front line of controversies over the environmental risks of mining the world’s unexplored seabeds.
Norway recently announced it was carrying out an environmental study needed to start mineral exploration and mining. Once that is completed, the govemment plans to have public comments on its environmental study and on a proposal to open areas for exploration and production by the end of 2022.
The demand for minerals is being driven by what are often called “clean” technologies. But the process of getting those minerals from the seabed could cause environmental problems.
Environmentalists including Britain’s David Attenborough have called for a temporary (暂时的) stop to deepseabed mining until more is known about how it affects sea life. The environmental group Greenpeace called for a total ban in a recent report. In another report, the High Level Panel for a Sustainable Ocean Economy, known as the Ocean Panel, also called for greater knowledge about the effects of deep-sea mining. The Ocean Panel is cochaired by Norway and has 14 member states that want to shape policy on the world’s oceans.
Norway is known as a major oil producer. But, the country of 5. 4 million people wants to find something to replace its top industry that is better for the environment and can grow in the future.
The move toward deep-sea mining follows three years of expeditions(探险). The Norwegian Petroleum Directorate, which carried out the work, said it found copper, zinc, cobalt, gold and silver. The expeditions also discovered large armounts of lithium and the rare earth metal scandium used in electronics and metal mixtures.

3 . When he was two years old, Ben stopped seeing out of his left eye. His mother took him to the doctor and soon discovered he had cancer in both eyes. After possible treatments failed, doctors removed both his eyes. For Ben, vision was gone forever.
But by the time he was seven years old, he had developed a technique for feeling the world around him: he clicked with his mouth and listened for the returning echoes. This method enabled Ben to determine the locations of open doorways, people, parked cars, garbage cans, and so on. He was echolocating: bouncing his sound waves off objects in the environment and catching the reflections to build a mental model of his surroundings.
Echolocation may sound like an improbable feat for a human, but thousands of blind people have perfected this skill, just like Ben did. The event has been written about since at least the 1940s, when the word ''echolocation" was first invented in a science article titled “Echolocation by Blind Men , Bats, and Radar.”
How could blindness give rise to the amazing ability to understand the surroundings with one's ears? The answer lies in a gift on the brain; huge adaptability.
Mother Nature filled our brains with flexibility to adapt to circumstances. Just as sharp teeth and fast legs are useful for survival, so is the brain's ability to reset, which allows for learning, memory, and die ability to develop new skills.
In Ben's case, his brain's flexible wiring repurposed his visual cortex for processing sound. As a result, Ben had more neurons available to deal with listening information, and this increased processing power allowed Ben to interpret soundwaves in shocking detail. Ben's super-hearing proves a more general rule: the more brain area a particular sense has, the better it performs.
1. How did Ben “see” after he had his eyes removed?| A．By using a walking stick. | B．By asking others for help. |
| C．By inventing a new system. | D．By echolocating surroundings. |
| A．Skill. | B．Task. | C．Sense. | D．Invention. |
| A．He laughs best who laughs last. | B．Actions speak louder than words. |
| C．God shuts one door but he opens another. | D．Man becomes learned by asking questions. |
| A．Culture Shock. | B．Human Biology. |
| C．Scientific Technology. | D．Environmental Protection. |
4 . An international group of electronic music composers is taking beats from the dance club to jungles and forests and back, all to help save nature's greatest singers. A Guide to the Birdsong of Mexico, Central America and the Caribbean is a new album that includes the sounds of endangered birds. The album will come out next month, whose proceeds will go directly towards efforts to save birds.
The whole project was born out of this idea of trying to combine birdsong, electronic music and conservation. A Guide to the Birdsong of Mexico, Central America and the Caribbean was organized by activist, music producer, Robin Perkins. He invited artists from each of the endangered birds 'homelands to build their own songs around the birds’ songs. There are contributions from ten artists in eight different countries.
First single Black Catbird was created by The Garifuna Collective, from Belize. Al Obando, guitarist and producer of the group, always took in national parks and viewed birds when on the road with the band. “There are no trails, and there are no signs there to tell you about what you reseeing,” Obando says. “So we're trying to do something for the birds and nature tourism.”
Another musician who responded to Robin's call is Tamara Montenegro, an artist from Nicaragua. She was shocked to hear of the serious situation of the Guardabarranco after being approached: “This beautiful creature I grew up adoring also faced the influence of the systematic human activities”. In response, she created a song inspired by this bird and the challenges it faces to live naturally.
The new album is the second edition, following on from A Guide to the Birdsong of South America, produced by Robin in 2015. That first album has raised, to date, over $15,000 benefitting conservation projects in South America. As with the first album, all of the money from the sales of the new album will support specific organizations, including Birds Caribbean.

5 . It’s easy to assume that a vacation to Bali will cost a small fortune. There are plenty of accommodations, food and local transportation, and even the spas offer massages and treatments at value prices. However, you can easily spend a week or two in Bali for under $2,000, without having to sleep on the beach. Here are a few things to consider when planning Bali on a budget.
What is the best time to visit Bali on a budget?
If you’re on a budget, consider visiting Bali during the lower, wetter season, which runs from October through March. The crowds will be fewer, and both hotel rates and flights from abroad are often cheaper, except during the holiday period between mid-December and early January, when crowds swell. The only trade-off for the lower prices is the wet season. This time of year isn’t always ideal for sunbathing, and serious rainfall can make outdoor activities, such as whitewater rafting and visiting waterfalls and rice terraces, less than appealing. That said, even during rainy season, it doesn’t usually rain all day long. Expect bursts of sunshine between the storms.
What is the cheapest way to get around Bali?
The absolute cheapest way to get around Bali is by local bus, but it can take a long time. There are also tourist buses, including hop-on, hop-off options, that travel between different hubs across the island. Bali is well-served by taxis, both of the car and motorbike variety, and the prices tend to be affordable by international standards. Most drivers will offer you a fixed rate for full-day hires or to get from point A to point B, rather than using a meter.
Remember to bargain; doing so is particularly easy when a driver is on his own rather than at a taxi stand.
How much does food cost in Bali?
If you’re into fine dining, you can end up spending a large chunk of your budget on food. Eating at the average restaurant geared towards tourists is the best way to have a meal in Bali on a budget. A good meal should cost you around 100,000 rupiah (around $7), but if you’re willing to subsist mostly off of local specialties such as nasi goreng (fried rice) and eat at local restaurants, you can expect to pay around 30,000 rupiah ($2) to get fed. Best of all, most hotels and guesthouses in Bali come with free breakfast, and many offer heavier options of noodles and meat that may keep you full until lunch.

| B．Passengers had better fix the price with drivers before the taxi pulls out from the station. |
| C．If on a tight budget, one is advised to visit Bali at the end of December every year. |
| D．It’s relatively economical to eat merely at average restaurants tailored to visitors. |

6 . The Sanxingdui Museum in southwest China’s Sichuan Province enjoyed huge popularity during the three-day Qingming Festival holidays by receiving nearly 20,000 visitors on the peak day, after the new archaeological discoveries brought international attention.
According to media reports, the museum saw over 15,000 visitors on Saturday, the first day of the Qingming Festival, breaking its record for daily visitors. And on the next day, more visitors swarmed into the museum to exceed 19,800. To cope with the large flow of people, on Sunday afternoon, the official Weibo account of the Sanxingdui Museum released the message to remind visitors of avoiding rush hours or rescheduling their visiting time.
The Sanxingdui Museum showcases various kinds of precious cultural relics unearthed at the site, such as the 2.62-meter-tall standing statue, 1.38-meter-wide bronze mask, 3.95-meter-high bronze tree. Earlier on March 20, Chinese archaeologists announced some new major discoveries made during the 37th excavation (挖掘) since its last excavation 35 years ago. The ruins were first discovered in the late 1920s and first excavated in 1934.More than 500 important cultural relics have been unearthed in the six newly-found pits. Since the new discoveries were known to the public, the number of people visiting the Sanxingdui Museum has increased sharply.
The museum said although they are open as usual, the newly-found pits have not opened to the public yet and the newly-excavated cultural relics are still under restoration and cannot meet the public currently. But a hall for cultural relic conservation and restoration will be in pilot operation in April and officially open on May 18. Visitors to it can see how the relics are restored, according to Zhu Yarong, vice director of the Sanxingdui Museum.
Dating back about 3,000 years, the Sanxingdui Ruins have shed light on the ancient Shu civilization and cultural origins of the Chinese nation, and have been regarded one of the most important archaeological discoveries in the 20th century.
