1 . What does being happy have to do with luck? To answer the question, a team of researchers from the UK and Hong Kong gave surveys to 844 English-speaking university students in Hong Kong. The survey questions measured their thoughts about luck and their happiness levels.
The researchers observed that less happy people believed in external (外在的) luck—the “Good luck with that!” variety that controls our good or bad. The authors point out that blaming “luck” for events and experiences makes people lose personal self-determination, which diminishes their sense of purpose and, in turn, their happiness. Believing we need luck to be successful may make us less determined to reach goals and take risks.
On the other hand, happier people believed themselves to be personally lucky. Viewing yourself as lucky, the researchers suggest, shows an active and positive attitude that develops hope and self-acceptance. Personally lucky people may feel more confident to try new things or act in ways that help others.
How does luck influence those people? Next, the research team asked those people to fill another survey. They found that people who believed in external luck were more likely to be less active, and in turn were less happy. Those who believe they’re especially lucky suffer less of a hit to happiness.
This study has its value. However, the data all come from surveys filled out by those surveyed, which means the responses may be too personal. Moreover, the use of a one-time survey means we cannot say that one thing causes another.
Although there are some limits, this study stresses the value of thinking about luck as something that benefits us. Moreover, this study helps explain why we call people “happy go lucky”—because happy is how we feel when we focus on how personally lucky we are.

2 . The CCU (Charity Cycling UK) recently called on to raise awareness (觉察，意识)of dooring after discovering that many people don’t know what it is. Dooring is when a driver or passenger opens the door into another road user (typically cyclist) without looking for other road users.
The CCU chief officer Paul told Glou Live: Some people seem to see car dooring as a bit of a joke, but it’s not and can have serious results. We want to see great awareness made about the dangers of opening your car door carelessly, and people to be encouraged to look before they open. w Among the 3,000 injuries, 2,009 were cyclists, resulting in five deaths but this might not be the whole of the danger. Not all car dooring incidents will be attended by police, so the CCU has written to call for a public awareness campaign urging(敦促)all car users, not just drivers, to look before opening vehicle doors.
One of the ways the CCU suggests is the “Dutch reach”, where people leaving a vehicle reach over and use the non-door side hand to open the door. In the Netherlands they are known for practicing a method, known sometimes as the “Dutch reach”, which we think could be successfully encouraged in the UK. If you're really concerned about opening a door into the path of a cyclist coming behind you, consider using what’s known as the “Dutch reach” to open the door. That will naturally turn you in your seat and give you a much better view of what's coming up alongside in the car.

3 . The personal computer has overtaken (赶上)the family dog as man's best friend, according to a study.
Researchers found that just 6 per cent of us believe that" most people rely more on their dog than they do on their PC", while 67 percent think the opposite to be true.
Even 38 percent of dog owners admitted to relying more on their PC than on their dog, although 36 percent disagreed. And 71 percent of 18 to 24-year-old dog owners said they relied more on their computer.
Paul Allen, editor of Computer-active magazine said, "These days you can even take your PC lor a walk, if you have a laptop or tablet." "It's only a matter of time until the first PC that fetches your slippers."
Researchers questioned 2,000 British adults to find out the change modern technology has brought to their home life. They found that male dog owners are almost twice as likely as female owners to rely on their computer than acaninecompanion.
Mr Allen said, "With broadband bringing them global news and newspaper sales falling, the family dog even misses out on the pleasure of taking the paper to his owner. " But it's not all had news for obedient（顺从的）dogs. "The family PC has given dog owners access to a wealth of resources and information that can help with the long-term care that a dog needs, " Mr Allen said.

4 . Yangsigang Yangtze River Bridge, the double-deck suspension (悬浮) bridge with the longest span in the world, opened to traffic on Tuesday after five years’ construction, according to a statement from the constructor.
It is reported that the bridge is 4. 13 kilometers long, with 12 lanes in both directions on the main I bridge. It is a long-span suspension bridge with the largest volume in the world, China Railway Major Bridge Engineering Group said. The bridge connects the Hanyang and Wuchang and its opening will ameliorate the urban expressway system, relieve traffic pressure across the river, and drive development in the area, according to the company.
On both sides of the upper deck of the bridge, there is a two-meter-wide footpath, with eight rest and sightseeing areas, where people can enjoy the river scenery. The lower level is designed with two non-motorized lanes, each 2. 5 meters wide. A 1. 5-meter wide walkway is also a feature of each side of the floor so pedestrians (行人) can walk on the lower level without getting caught in the rain.
Chief designer of the bridge, Xu Gongyi, said, “Considering navigation and traffic volume, the main span of the bridge is 1, 700 meters, which is the second-largest in the world and also the largest in bridges of double-deck structure.”
According to Luo Ruihua, project manager of the bridge, the Yangsigang Yangtze River Bridge has set several records in the process of its construction. The designed tension of each of the two main cables (钢索) is 65, 000 tons.
From 2014 to 2019, builders have shown the world the speed of China. The bridge not only enhances Wuhan’s reputation as a “bridge museum”, but also represents a super project of a new era.

5 . There are many things that we can do in our own ways which will help save the environment. What are some of these ways to save the environment? Let’s take a look at a list of them.
There won’t be enough water before we need to fight for clean and fresh water. That is why saving water and preventing water pollution becomes very important. Keep simple things in mind like turning off the tap when you are brushing teeth. Don’t often take a shower. Don’t pour oil into the drains. Don’t throw rubbish into the river.
Save paper to save trees. Make sure that you use both sides of paper before throwing it away. If you can, try not to use paper as possible as you can and do not forget to recycle paper. Also, using cloth bags instead of paper bags can save much Paper. This is one of the best ways to save our environment.
Recycling is important. It makes sure that the environment is not more polluted. Recycling does not simply include recycling paper, but things like plastic, metal and office supplies like pens, ink and more. This makes sure that they are changed into material that is reusable and also puts less pressure on the environment.
What are the ways to save energy? Turn off the lights and computers before you leave. Use cold water instead of hot water to wash clothes, use the stairs instead of the lift and keep the air conditioner on moderate setting(设置)to save energy.
In a word, try our best to do something to save our environment, and we will do something helpful to save ourselves.

6 . With attractiveness in its structure (结构) and in its presence, the Eiffel Tower has become a great site of France and Gustave Eiffel's architectural wonder. Also known as La Tour Eiffel, the Eiffel Tower is climbed by millions of visitors every year. Do you know how tall the Eiffel Tower is? Standing at 1, 063 feet tall, this is the second tallest building in France after the Millau Viaduct, a road bridge across the river Tarn. Nicknamed La Dame de Fer, or the iron lady, this tower is a symbol of France even today.
The tower was built between 1887 and 1889 as the entrance for the World Fair. This event was to mark the 100th celebration of the storming of the Bastille and the French Revolution. Ironically, at first, the tower was considered unpleasant by a lot of art enthusiasts. Several members from the arts community said it only ruined the empty skyline of the Paris city. French novelist Guy de Maupassant expressed his dislike for the tower by eating lunch every day at the tower's restaurant — his explanation was that it was the only place in Paris where one could not see the structure! Whatever may have been the opinion about the structure at the time, the fact remains that it became an object that attracted many people around the world.
The tower, weighing 10, 000 tons, includes several non-metallic (非金属的) parts as well. The metallic parts used in the structure weigh 7,300 tons, which, if melted (熔化), will fill up a 125-meter square with a depth of 6cm. At the time when the tower was built, the great structure amazed lots of engineers and common people. The Eiffel Tower needs 50~60 tons of paint every seven years to keep the rust (铁锈) away.
The structure decorates the Parisian skyline. Being one of the most visited sites in the world, the Eiffel Tower still remains an architectural wonder!

7 . A teenager of 17 walks into a corner store and grabs a Coca-Cola, but the cashier refuses to sell it to him because he is underage. That rule is expected to soon become reality in parts of Mexico, as lawmakers in several states push legislation (立法)to keep junk food away from children. know it can sound a bit difficult but we have to take action now," says Lopez, a lawmaker in Oaxaca's Congress.
More than 70,000 Mexicans have died from COVID-19, the world's fourth-highest recorded death toll, tracked by Johns Hopkins University. 89% of those who died in Mexico had an underlying medical condition such as obesity, diabetes (糖尿病)，high blood pressure and heart problems. That has led to a new urgency to change diets so that the younger generation doesn't suffer those illnesses.
The critics, however, say the leaders are using preexisting health conditions in COVID-19 patients to distract from a weak government response to the virus outbreak. Yet few people would deny that the country consumes large amounts of sugar-sweetened drinks and processed snacks with little nutrition --- or that Mexico has a major weight problem.
Oaxaca's governor approved the state's junk food prohibition last week. Legislators still have to complete the legal systems, and punishment could include fines and even jail. Lopez says legislators from all over the country have called her for advice. Many other states are debating a junk food ban. However, a nationwide law would not be easy. "There are powerful commercial interests that least want it to happen, but we must prioritize the well-being of our children," Lopez says.

8 . China will have the most 5G connections of any nation by 2025, according to a new study, while Europe will fall behind Korea, the United States and Japan in terms of 5G penetration(渗透)by that year.
5G is the fifth generation of network technology. It is expected to bring unbelievable speeds to Internet users, with some operations running 10 times faster than on 4G networks. 5G is also expected to unlock the potential in a lot of new services, including artificial intelligence, science of robots self-driving cars, and the Internet of things.
The GSMA said that China's three major mobile operators-China Unicorn, China Mobile, and China Telecom-are already moving ahead with 5G networks. While most nations will have 5G by updating existing foundations, the study noted that China plans to build part of its 5G networks.
One of the most distinguishing(显著的) factors between Chinese mobile operators and those in the rest of the world is the intention to erect the new and independent 5G networks. That is, China is determined to build a completely advanced 5G. The high cost underlines China's seriousness about paying whatever it takes.
Korea will lead the world in terms of 5G penetration in 2025, when 66 percent of the nation's total connections will be 5G, according to GSMA. This compares to 50 percent in the US, 49 percent in Japan, 36 percent in China, 30 percent in Europe, and a global average of 18 percent. Out of the five economies leading on 5G, Europe will have the lowest participation in 2025, as the area is moving more slowly in having its 5G networks.
1. What will 5G bring?| A．A completely new pattern for daily life. |
| B．Excellent networks and national safety. |
| C．Amazing speeds for public transportation. |
| D．Realizing the potential in many new services. |
| A．It will develop rapidly. | B．It may be lack of government support. |
| C．It will move forward slowly. | D．It may fall behind Europe. |
| A．bring up. | B．set up. | C．turn up. | D．pick up. |
| A．More than half Koreans use 5G in 2025. | B．Chinese cannot own 5G in 2025. |
| C．Only five countries will have 5G in 2025. | D．Europe will pay little attention to 5G in 2025. |
9 . Israeli researchers say they have invented a reusable face mask that can kill the coronavirus with heat by drawing power from a mobile phone charger.
The disinfecting(消毒)process takes about half an hour-and users should not wear the mask while it is plugged in, said Professor Yair Ein-Eli, who led the research team at Technion University in Haifa. TI new mask has a USB port that connects to a power source such as a standard cellphone charger that heats an inner layer of carbon fibres to 70 degrees Celsius, high enough to kill viruses.
Ein-Eli said disposable masks, in high demand globally during the health crisis, were not economically or environmentally friendly. “This is our solution,” he said.
Professor Allon Moses, an infectious diseases expert at Jerusalem’s Hadassah Medical Center, said there was “no question” that a half hour’s exposure to 70-degree heat would kill the coronavirus. But he cautioned that repeated heating could “damage the masks paper or fabric and spoil its ability to protect from diseases in the future.”
During testing, the prototype was exposed to 20 heating cycles, each for half an hour, with no damage on durability, Ein-Eli said. “We can guarantee it up to a few dozen cycles, without any risk,” he added.
The prototype looks like a standard N95 face mask, with a valve(阀) at the front and bands to hold it in place around the head. The researchers submitted a patent for the mask in the United States in late March and say they are discussing commercializing the product with the private sector. It will likely sell at a $ l premium over the price of a typical disposable face mask, the researchers say.
1. How long does the disinfecting process usually take?| A．Around 20 minutes. | B．around 30 minutes. |
| C．Around 60 minutes. | D．Around 70 minutes. |
| A．To kill viruses thoroughly. | B．To spread a novel idea. |
| C．To replace the traditional ones. | D．To make reusable and friendly ones. |
| A．The reusable face masks were unhealthy. |
| B．70-degree heat would hurt people in a way. |
| C．The cost of reusable face masks may be high. |
| D．The function of mask to prevent diseases was ruined. |
| A．Fine. | B．Extra. | C．Currency. | D．Face value. |
10 . The ancient tale of the Country Mouse and the Town Mouse was only the first to emphasize rural folk’s supposed simplicity when compared with more complex urbanites. However, neuroscientists announce that, in fact, it is city living that can dull the wits.
The new study led by Dr. Spiers at Nantes University describes how they used a dataset from 4 million people of a computer game, which tests navigating skills by asking players to memorise a map showing the location of checkpoints and then measuring how well players can find them, guided only by their mental map. Dr. Spiers and his colleagues examined the 4 million people from 38 countries, and found that the strongest indicator of a high score was a player’s age — older people performed relatively poorly, which agrees with what researchers know about age-related cognitive (认知的) drop. But the benefit of rural living was strong enough to offset some of that. Data showed that a 70-year-old who grew up in the countryside had the navigational abilities of an average 60-year-old across the dataset.
There is a huge gap between the navigation skills of rural and city people, and the researchers think they know why. Dr. Spiers says that the brain’s navigational abilities probably weaken in the less challenging city environment because they are not being used as much. Although cities may appear more detailed, they also feature more clues to help residents find their way, such as numbered streets. In the countryside, however, one field tends to look much the same as another, so there are fewer landmarks to help guide the way.
Neuroscientists already know that living and working in more complex environments can influence the function and structure of the brain. Brain scans of London taxi drivers, who have gained a good memory of the city’s streets, show that they tend to have an enlarged hippocampus — a region of the brain acting as a neural GPS, sensing position and path on an inside map of the environment.
The harmful effect of city living on navigation is probably most serious in people under 16-18, Dr. Spiers says, because their still-developing brains respond and change the most according to outside stimuli (刺激). And while people who live in cities with young children should not be alarmed, the study does raise some interesting ideas for urban planners: keep their city designs not so simple perhaps. And for everyone else, it might be an idea to turn off maps on the phone.
