“...This season is all I have left togive. My heart can take the pounding(重击). My mind can han-dle the grind(苦差事) but my body knows it's time to say goodbye"

  “Kobe Bryant is one of the greatest players in the history of our game. Whether competing in the Fi-nals orhoisting jump shots after midnight in an empty gym,  Kobe has an unconditional love for the game.

    I join Kobe's millions of fans aroundthe world in congratulating him on an outstanding NBA career and thank him forso many thrilling memories.”

    Australian scientists are trying to give kangaroo-style stomachs to cattle and sheep in order to cut the greenhouse gases they send out, which is thought to be responsible for global warming.

    Thanks to special bacteria in their stomachs, kangaroo flatulence (肠胃气胀) contains no methane and scientists want to transfer that bacteria to cattle and sheep who produce large quantities of the harmful gas.

    While the usual image of greenhouse gas pollution is a billowing smokestack, pushing out carbon dioxide, farm animals' passing wind contribute a surprisingly high percentage of total emissions in some countries.

    “Fourteen percent of emissions from all sources in Australia are from enteric methane from cattle and sheep,” said Athol Klieve, a senior research scientist with the greensland state government. “And if you look at another country such as New Zealand, which has got a much higher agricultural base, they are actually up around 50 percent,” he said.

    Researchers say the bacteria also make the digestive process much more efficient and could potentially save millions of dollars in feed costs for farmers. But it will take researchers at least three years to isolate the bacteria before they can even start to develop a way of transferring it to cattle and sheep.

    Another group of scientists, meanwhile, have suggested Australians should farm fewer cattle and sheep and just eat more kangaroos. And about 20 percent of health-conscious Australians are believed to eat the national symbol already.

    It's low in fat, it's got high protein levels and it is very clean in the sense that basically it is free-range(放养的) animal,” said Peter Ampt of the University of New South Wales' institute of environmental studies.

    Golden Gate Bridge

    Located in San Francisco,the Golden Gate Bridge started in the year 1933 to connect the San Francisco Peninsula with Marin County.It was finally thrown open to public traffic in 1937.It cost $25.7 million in the construction.Till the year 1957,the Golden Gate Bridge,at a length of 2,737 meters,was the longest suspension bridge in the world.

    Brooklyn Bridge

    The Brooklyn Bridge is located in Brooklyn.It is one of the oldest suspension bridges in the United States, having been opened in the year 1883.The length of the bridge is 1,843 meters.The bridge has been featured in several Hollywood movies.

    George Washington Bridge

    Also known as the Hudson River Bridge and the Columbus Bridge,the George Washington Bridge which connects Fort Lee to Manhattan came into use in 1931 after a construction period of almost 4 years.It is a two level suspension bridge that cost about $52 million to build.

    Mackinac Bridge

    This is the third biggest suspension bridge in the world at a length of 8,038 meters.The architect of this bridge was Dr.David B. Steinman who directed the construction of the bridge which started in the year 1054 and opened to the public in 1958.People using this bridge are charged a certain amount of money.

    Navajo Bridge

    Located in Arizona,this bridge crosses the Colorado River and is almost 250 meters long.The construction of this bridge started in the year 1927,ending two years later,costing $390,000.In the 1990s a second bridge was built which was opened to the public in 1994.The first bridge is now used only by pedestrians.

    Driving a car is not just handling controls and judging speed and distance. It requires you to predict what other road users will do and get ready to react to something unexpected. When alcohol is consumed, it enters your bloodstream and acts as a depressant (抑制药),damaging eyesight, judgment and co­ordination(协调),slowing down reaction time and greatly increasing the risk of accidents. Even below the drink driving limit, driving will be affected.

    Alcohol may take a few minutes to be absorbed into the bloodstream and start action on the brain. Absorption rate is increased when drinking on an empty stomach or when consuming drinks mixed with fruit juice. To get rid of alcohol from the body is a very slow process and it is not possible to speed it up with any measures like taking a shower or having a cup of tea or coffee.

    The present Road Traffic Ordinance states clearly that the limit of alcohol concentration is： 50 milligrams of alcohol per 100 ml of blood； or 22 micrograms of alcohol per 100 ml of breath; or 67 milligrams of alcohol per 100 ml of urine (尿液)．

    Drivers who cause traffic accidents, or who commit a moving traffic offence or are being suspected of drink driving will be tested.

    Any driver found drinking beyond the limit will be charged. The driver declared guilty may be fined a maximum of HK $ 25000 and be sentenced to up to 3 years in prison and punished for 10 driving­offence points; or temporarily banned from driving.

    The same punishment applies to failing to provide specimens (样本)for breath, blood or urine tests without good excuse.

    Drink driving is a criminal offence. Be a responsible driver, think before you drink. For the safety of yourself and other road users, never drive after consuming alcohol.

    A science teacher from rural Kenya who gives away most of his salary to help poorer students has been awarded the world's best teacher and $ 1 million, beating 10,000 nominations from 179 countries. Peter Tabichi, 36, a maths and physics teacher at Keriko secondary school in Pwani Village, has won the Varkey Foundation Global Teacher Prize 2019.

    Tabichi gives away 80% of his income to help the poorest students at the poorly-equipped and overcrowded school who could not otherwise afford uniforms and books. More than 90% of his students are from poor families and almost a third are orphans or have only one parent. Drug abuse, teenage pregnancies, leaving off their studies, young marriages and suicide are common. Students have to walk 7 km along roads that can become impassable in the rainy season to reach the school and the area can be affected by drought and starvation.

    Despite only having one computer, a poor Internet connection and a student-teacher ratio of 58:1, Tabichi started a "talent nurturing club" and expanded the school's science club, helping students design research projects of such quality that many now qualify for national competitions.

    His students have taken part in international science competitions and won an award from the Royal Society of Chemistry after using local plant life to generate electricity. Tabichi and four colleagues also give struggling students one-to-one tuition in maths and science, visiting students' homes and meeting their families to identify the challenges they face.

    Accepting the prize, Tabichi said Africa's young people would no longer be held back by low expectations." Africa will produce scientists, engineers and entrepreneurs whose names will be one day famous in every corner of the world." he said.

Chinese delivery driver, Gao Zhixiao, was featured on the cover of Time magazine in March because of his sense of commitment. Alongside five others, he was picked by the magazine as one of heroes among the novel coronavirus outbreak.

Ever since COVID-19 broke out, many restaurants shut down or switched to takeout-only services. Millions of people have been staying at home to avoid getting infected. "People choose to order food online or buy fruit and vegetables to cook at home," Gao told Time. As a result, delivery orders dramatically increased, placing a huge burden on delivery company.

Born into a poor family in the Ningxia Hui autonomous region, Gao started to make a living in Beijing at age 16. After the novel coronavirus broke out, Gao hesitated for a second to continue working, but then picked up orders because he thought customers might be in need.

Due to the danger of person-to-person transmission, Gao must take care to avoid spreading viruses during his route around Beijing, including taking a regular health test and spending 20 minutes disinfecting his motorcycle and clothes each morning. Besides delivering goods, Gao once willingly cooked for an elderly customer who was living alone at her home.

It is the commitment of ordinary people like Gao that has made the biggest contributions in the fight against COVID-19.
