Last Thursday, the world’s first self-driving, electric container ship made its first trip to Oslo, Norway. The ship’s owners aim to cut pollution by transporting large quantities of products by water on the southern coastal of Norway instead of by truck.
The ship, called the Yara Burkeland, is owned by Yara, a company that makes fertilizer (肥料). The company wanted to develop a zero-emission (零排放的) ship that was completely self-driving. Yara worked with a ship-building company called Vard and the technology company Kongsberg to develop the ship. The company says that in the future everything, including loading and unloading the ship, will be handled completely automatically.
The Yara Birkeland can carry 120 large containers like those pulled by trucks. But the ship is fully electric and is powered by batteries. The company says the ship has roughly as many batteries as 100 electric cars. The electricity that will be used to recharge the batteries is from renewable hydroelectric (水力发电) sources, so there’s no pollution at all.
The Yara Birkeland won’t usually be going to Oslo, and it won’t be traveling far, either. It will travel along a regular route from Yara’s factory in Porsgrunn up to the port in Brevik. By road, that’s a distance of about 14 kilometers. Yara normally uses diesel-powered (柴油动力的) trucks to move fertilizer between these locations.
Now, with the Yara Birkeland moving huge amounts of fertilizer by water, the company expects to suspend 40,000 yearly trips by diesel-powered trucks. That will prevent about one million kilograms of carbon emissions every year.
In the future, as an autonomous ship, the Yara Birkeland is expected to operate without any human involved. Yara plans to spend the next two years improving and testing the ship. But, as with many autonomous cars, the ship will continue to have humans watching over even if it is driving by itself.

【推荐1】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.

【推荐2】The world’s longest sea bridge has opened. It links Hong Kong and Macau to mainland China. The bridge is called the Hong Kong-Zhuhai-Macau Bridge and is 55 kilometers long. The bridge took over a decade to construct. Builders had to make artificial islands (人工岛) in the Pearl River Delta (珠江三角洲) to provide the supports for the bridge. There is also a 6.7-kilometre underwater tunnel in the middle of the bridge. This is to allow ships to sail through the Delta. The new bridge is longer than 14 Golden Gate Bridges lined up end to end. The bridge will greatly cut the time it takes to travel from mainland China to Hong Kong and Macau. The journey time to Macau has been cut from over three hours to just 30 minutes.
Chinese President Xi Jinping attended the opening ceremony of the bridge on Thursday. He hopes the new crossing will help to connect 68 million people in 11 different cities. China’s government believes that up to 29,000 cars will cross the sea link daily by the year 2030. A trade and tourism expert said: “This makes Hong Kong a lot more accessible for goods, passengers and trade, so this is a benefit from the economic perspective.” The bridge will be open to tourists to drive across it. However, local car owners will not be able to cross the bridge unless they have a special permit. Most drivers will take a shuttle bus to make the journey. The shuttle buses will cost $8-$10 for a single trip.

【推荐3】Extreme sorrow claws my mind. I am a statistic. When I first got here. I felt very much lonely. I found no sympathy. I saw only thousands of others whose bodies were as badly mangled as mine. I was given a number and placed in a category, which was called “traffic death”.
The day I died was an ordinary school day. How I wish I had taken the bus! But I was too cool for the bus. I remember how I wheedled (哄骗) the car out of Mom. “Special favor,” I pleaded. “All the kids drive.” After school, I rushed to the parking lot, excited at the thought of driving a car and being my own boss.
It doesn’t matter how the accident happened, I was going too fast taking crazy chances. But I was enjoying my freedom and having fun. The last thing I remember was passing an old lady who seemed to be going awfully slow. I heard a crash and felt a terrific shake. Glass and steel flew everywhere. My whole body seemed to be turning inside out. I heard myself scream.
Suddenly, I awakened. It was very quiet. I saw a police officer and a doctor. I was saturated with blood. Pieces of jagged glass were sticking out all over. Strange that I couldn’t feel anything. Hey, don’t pull that sheet over my head. I can’t be dead. I’m only 17. I’m supposed to have a wonderful life ahead of me. I haven’t lived yet. I can’t be dead!
Later I was placed in a drawer. My folks came to identify me. Why did they see me like this? Why did I have to look at Moms eyes when she faced the most terrible ordeal of her life? Dad suddenly looked very old. He told the man in charge, “Yes — he is our son.”
Please — somebody — wake me up! Get me out of here. I can’t bear to see Mom and Dad in such pain. My grandparents are so weak from grief they can barely walk. My brother and sister move like robots.
Please don’t bury me! I’m not dead! I promise if you give me just one more chance, God. I’ll be the most careful driver in the whole world. All I want is one more chance. Please, God, I’m only 17.

【推荐2】Scientists in South Korea have proven that a new technology will cut the time it takes to charge electric cars to just nine seconds. And even those plugging-in at home will have the time reduced from 10 hours to 3 minutes.
The new device uses the laws of quantum (量子) physics to power all of a battery’s cells at once-instead of one at a time-so recharging takes no longer than filling up at the pump. Electric cars were rarely seen on the roads 10 years ago, but millions are now being sold every year and it has become one of the fastest growing industries, but even the fastest superchargers need around 20 to 40 minutes to power their car.
Scientists at the Institute for Basic Science (IBS) in South Korea have come up with a solution. Co-author Dr Dario Rosa said the consequences could be far-reaching.
The concept of a “quantum battery” was first proposed in a paper published by Alicki and Fannes in 2012. It was theorized that quantum resources can be used to vastly speed up battery charging. The researchers used quantum mechanics to model their super fast charging station with calculations of the charging speed showing that a typical electric vehicle with a battery containing around 200 cells would recharge 200 times faster. The group went further to provide a specific way of designing such batteries. This means charging times could be cut from l0 hours to 3 minutes at home and from around 30 minutes to just a few seconds at stations.
Co-author Dr Dominik said,“Of course, quantum technologies are still in their initial stage and there is a long way to go before these methods can be used in practice. Research findings such as these, however, create a promising direction and can incentivize the funding agencies and businesses to put more money in these technologies. If employed, it is believed that quantum batteries would completely revolutionize the way we use energy and take us a step closer to our sustainable future.”

【推荐3】Imagine getting ready for bed, brushing your teeth, setting your alarm and then putting a device on your head that allows you to control your dreams. It might sound like something out of a Christopher Nolan movie, but it’s also the real-life promise of a new futuristic-looking headband called Halo, currently in development by US tech start-up Prophetic.
Planned for release in 2025, Halo aims to allow you to have more lucid dreams-dreams where you are aware that you’re dreaming. In some cases, you might also exert (施加) a degree of control over what happens in these dreams, perhaps in ways that benefit your waking life, such as solving work problems, visiting faraway lands, practising guitar and much more.
The state-of-the-art approach taken by the team behind the Halo device involves two stages. First, they are using EEG (脑电图) and fMRI (功能性磁共振成像) to collect vast amounts of brain data from volunteers experiencing lucid dreams. This information will be key for the second main area of investigation, which involves using TUS (超声) to manipulate brain activity in a way that will induce (诱导), sustain and influence lucid dreams by employing high-frequency sounds.
So, is there any reason not to be excited about the Halo headset? One issue is that TUS is a relatively new approach to brain stimulation and it's not entirely clear what the long-term consequences of zapping your brain with high-frequency sounds might be. A second Issue is that some sleep scientists believe dreams have basic functions. One potential concern is that by using a device to alter (更改) the nature of your dreams, you risk interfering with the usual purpose of your dreams: A final consideration is that there are already several established techniques for inducing lucid dreams that do not involve cutting-edge technology, such as training by repeatedly pairing a sound with deliberate thoughts of self-awareness, which are cheaper than the Halo headset.
With all these issues taken into consideration, the journey ahead is not without obstacles, and only time will reveal the future path of Halo.

【推荐1】The cancer death rate in the U.S. fell by the most on record as advances in treatments for lung tumors (肿瘤) like video-assisted surgery helped prolong the lives of patients.
The death rate from cancer has been gradually declining for 26 years, thanks in large part to fewer people smoking cigarettes. But from 2016 to 2017, the most recent period available, it dropped by 2.2%, the most ever in a single year, according to a report released Wednesday by the American Cancer Society. That compares with an average 1.5% yearly decline over the decade. The drop translates to roughly 2.9 million fewer cancer deaths than would have occurred had death rates remained at their peak. For lung cancer specifically, the death rate declined 4.3% annually from 2013 to 2017.
"It is really lung cancer that is driving this," said Rebecca Siegel, scientific director of surveillance research at the American Cancer Society, and lead author on the new study. "We found increases in survival for lung cancer at every stage in diagnosis.”, She attributed the lower deaths to improvements in treatments, including video-assisted surgery that enables more patients with early lung tumors to become eligible for operations; more precise radiation treatment; and better scanning technology that allows doctors to better assess the stage of tumor, so the patient gets the best treatment right away. At later stages of illness, new, targeted drugs that aim at specific disease-causing genes are helping patients whose tumors have those genetic flaws (缺陷).Overall, lung cancer death rates have dropped by 51% for men since their peak in 1990, and by 26% for women since their peak in 2002.
There's the potential for more progress in future reports. That's because the latest death-rate statistics go only through 2017, and likely don't include the potential impact in lung cancer death from immune-therapy drugs. They became widely used in lung cancer only in the past few years.
The report, based on U.S. government data, isn't all good news. Prostate (前列腺)cancer death rates have leveled off recently after a period of decline. That may be because many doctors pulled back on using the controversial prostate-specific antigen test, or PSA, which can spot the disease but can lead to over-treatment of men who may never have died from their tumors.
"Though it was definitely causing harm, it was also contributing to declines in death," Siegel said. What's needed now is better screening tests to detect only the prostate cancers that will go on to cause harm.
Population death rates are considered one of the most reliable ways of measuring progress in cancer treatment and prevention. By contrast, cancer survival rates can sometimes be influenced by improvements in diagnosing tiny, early stage tumors that wouldn't necessarily be deadly.

There are some special features of poetry, which make it quite different from other forms of literature. First of all, poems have rhythmic patterns. Generally most parts of a poem follow the same form of rhythm. Poems may have rhyme, but they don't have to. The lines are neatly arranged together so that they express a particular feeling or emotion.
There can be various types of poems but according to the pattern or the form, there are mainly three types:
Lyrics: The lyric mainly concentrates on human thoughts and emotions rather than a story. Lyrics always bear song-like appeal. These are mainly short poems. Popular lyric poem forms are the elegy, the ode and the sonnet. William Shakespeare, Edmund Waller and Keats are some of the greatest lyric writers of all times.
Narrative poems: This type of poetry tells a story. Narrative poems are usually long poems. Epics(史诗) and ballads fall under this type. Some of the greatest epic poets are John Milton, Dante, Edgar Allan Poe, Alexander Pope, William Shakespe are, etc..
Dramatic poems: Any drama that is written in verse is a dramatic poem. These poems generally tell a story. Black verse, dramatic monologue(独白) and closet drama belong to this type. William Shakespeare, Christopher Marlowe and Ben Jonson are some of the greatest dramatic poets.
Whatever the form is, one thing, which cannot be denied, is that poetry is one of the most powerful tools to express our feelings.
1. What do we know about lyrics?
①They are similar to songs.

【推荐3】It has always been thought that alcohol causes people to put on weight because it contains a lot of sugar, but new research suggests a glass a day could form part of a diet. Looking at past studies they found that, while heavy drinkers do put on weight, those who drink in moderation can actually lose weight.
A spokesman for the research team at Navarro University in Spain says, “Light to moderate alcohol intake, especially of wine, may be more likely to protect against, rather than promote, weight gain.” The International Scientific Forum on Alcohol Research reviewed the findings and agreed with most of the conclusions, particularly that data do not clearly indicate if moderate drinking increases weight.
Boston University’s Dr. Harvey Finkel found that the biologic mechanisms(生物学机制) relating alcohol to changes in body weight are not properly understood. His team pointed out the strong protective effects of moderate drinking on the risk of getting conditions like diabetes (糖尿病), which relate to increasing obesity. Some studies suggest that even very obese people may be at lower risk of diabetes if they are moderate drinkers.
The group says alcohol provides calories that are quickly absorbed into the body and are not stored in fat, and that this process could explain the differences in its effects from those of other foods. They agree that future research should be directed towards assessing the roles of different types of alcoholic drinks, taking into consideration drinking patterns and including the past tendency of participants to gain weight.
For now there is little evidence that consuming small to moderate amounts of alcohol on a regular basis increases one’s risk of becoming obese. What’s more, a study three years ago suggested that resveratrol (白藜芦醇), a compound present in grapes and red wine destroys fat cells.
