At exactly eleven Sir Percival knocked and entered, with anxiety and worry in every line of his face. This meeting would decide his future life，and he obviously knew it.

    "You may wonder, Sir Percival,”said Laura calmly, “if I am going to ask to be released (免除）from my promise to many you. I am not going to ask this. I respect my father's wishes too much.”

    His face relaxed a little, but one of his feet kept beating the carpet.

    "No, if we are going to withdraw. (退出）from our planned marriage, it will be because of your wish, not mine.

     “Mine?” he said in great surprise. “What reason could I have for withdrawing?^'

    "A reason that is very hard to tell you," she answered. "There is a change in me.”

    His face went so pale that even his lips lost their color. He turned his head to one side.

    "What change?" he asked, trying to appear calm.

     “When the promise was made two years ago,” she said, ⁴⁴ my love did not belong to anyone. Will you forgive me, Sir Percival, if I tell you that it now belongs to another person?”

    “I wish you to understand, “Laura continued, “that I will never see this person again, and that if you leave me, you only allow mc to remain a single woman for the rest of my life. All I ask is that you forgive mc and keep my secret."

    ‘I will do both those things, “he said. Then he looked at Laura, as if he was waiting to hear more.

    "I think I have said enough to give you reason to withdraw from our marriage, “she added quietly.

    “No. You have said enough to make it the dearest wish of my life to marry you, ” he said.

BLOOD DRIVE ＆ MARROW（骨髓）REGISTRATION

    "These patients deserve a chance at a normal, happy future and they rely on the kindness of the strangers to make that happen.

    — Daisy, Isabelle's Mother

    Isabelle is the daughter of Daisy and Saman Mirzaei. In January 2008 Isabelle was diagnosed（诊断）with a genetic blood disorder，beta thalassemia. Isabelle's body is unable to produce healthy red blood cells. As a result, Isabelle has been receiving blood transfusions (输血) every 4-6weeks since she was 11 months old. A lifetime of regular transfusions can lead to serious medical problems. Her only chance at a normal, healthy life is to have a marrow transplant.  Isabelle is an only child, so doctors have started a search for an unrelated marrow donor through The Match Registry. The Mirzaei family asks that you consider helping patients like Isabelle by registering to be a marrow donor and give the gift of life, the gift of blood.

    Sumeja Tulic had moved from London to New York nine months ago to attend journalism school. Yet her time in New York met with a season of never-ending ugliness in politics and acts of terrorism(恐怖主义) around the world. “One day you laugh, and then you're angry,” said Tulic. As she walked toward the subway station, she thought, “I want to see something nice. Enough of this craziness.”

    At the City Hall station, she saw a man resting against a pillar(柱子), the way anyone might, waiting for the train. The stillness was interrupted(打断) by an announcement that the next train was two stations away. Then Tulic saw the man at the pillar falling forward onto the tracks.

    The man who had fallen was not moving. In what seemed like an instant, three men jumped down to help.

    I don't know where these men got the intelligence and the quickness," Tulic said. "The man who fell was about six feet tall and quite heavy. He was kind of stuck in the tracks. It was terrifying to know that the train was coming. Will it stop? Will they succeed in pulling him out?"

    On the tracks, the unconscious(失去知觉的) man was put into a sitting position by the three men, who then lifted him from below to others who lifted from above and rolled him onto the platform. Then the rescuers were themselves rescued, pulled back to safety by helping hands. As soon as they were all clear, the train pulled in. People getting off the train walked around this unconscious man.

    Two of the men who had jumped onto the platform were holding his hands. “They were saying, ‘You're going to be fine,'” Tulic said. “This was an additional layer of goodness.”

    Doctors arrived, and the man was taken to a local hospital with serious but non-life-threatening injuries.

    “That is the greatest thing,” Tulic said. “The infrastructure(基础) in this city of millions is the people themselves providing, being there for others, without even knowing the person, who he is. It was beautiful to see.”

    We all have different ways to navigate (导航) when lost—whether asking a stranger for help, consulting an old-school map or simply following our nose. But on a bike, the risks are higher. One wrong turn or that you're in a traffic jam with two lanes between your bike and the nearest pavement may ruin your good mood. Although cyclists, of course, managed to navigate before smart phones, cyclists can make two choices: a few stay calm and embrace getting lost, and the rest turn to a navigation app.

    Google Maps added a directions function for cyclists in 2015 in the US and Canada, and two years later across Europe. And while there are dozens of other apps now offering a similar service, Google Maps has the demerits for many, so the app seems to be falling behind expectations.

    As someone with no sense of direction, I knew it wouldn't be easy when I started cycling earlier this year. I appreciated that the app gave me two warnings before I needed to turn off a road, and automatically recalculated my route if I accidentally went off course. But still, it wasn't a smooth process. Google Maps thought I could cut across a double carriageway with no breaks in its barrier, assumed I knew what it meant when it told me to “head west”, and thought nothing of taking me the wrong way down a busy one-way street.

    Cyclists don't just want safety—they want convenience. Londoner Robson Smith regularly cycles between Clap ham and the City of London and would like to see Google Maps calculate routes where his bike is allowed on public transport and more choice of the type of routes he can take. “Google tends to calculate the most common and comfortable cycle routes. It would be better to have an option which included the fastest route, regardless of comfort,” he says.

    For this reason, Robson says he uses the app Cycle Streets instead. It offers a choice of four different route modes, based on the type the user wants, and saves previous routes. It also tells you how many calories a route burns, how many traffic lights you wilt encounter, and how busy it is.

When it comes to sitting properly, we all know the correct way even if we don't do it to the letter. No crossed legs, bottoms touching the back of the chair and feet on the ground. But even if you're doing it right, sitting for long periods is shockingly bad for you. It has been described as the new smoking, linked to heart disease and even cancer. There is no doubt we should all try to do less of it. But perhaps we could also do it better.

A classic survey, published in 1953, described 100 different sitting postures adopted by 480 cultures around the world. Among the most common were sitting cross-legged, kneeling and the deep squat (深蹲), with feet flat on the ground and bottoms resting on or just above it. Even in Western cultures, these are preferred sitting positions among young children. But Westerners tend to prefer chair use from an early age, insisting children sit on seats in school.

One big problem with this desire for chairs is that they make sitting so, well, sedentary (久坐不动的). Consider the Hadza, a group of hunter-gatherer people in Tanzania. They spend around 9 hours a day sitting. However, they squat and sit on the ground in various positions, and this involves high levels of muscle activity. The supportive nature of chairs, with their high backs and armrests, removes this effort perhaps the reason that people love them.

So what's the best way to sit? Josette Bettany-SaItikov at Teesside University, UK has found that kneeling can help keep the spine in a better position as does squatting. We might also take inspiration from traditional cultures like the Hadza. "Use a variety of postures and preferably not just still postures but some which allow movement," says Bettany-Saltikov.

Bettany-Saltikov believes that we should be rethinking what it means to do a desk job. "We still need to design workplaces that enable people to be productive while being lightly active, like with under-table cycling or walking desks," she says. For now, if your job is sedentary, don't forget to stand up regularly and move around.

China's Tianwen 1 Mars probe (探测器) conducted its fourth orbital correction on Friday evening, as the spacecraft makes ready for its arrival in orbit around Feb. 10, according to the China National Space Administration.

The name comes from the long poem Tianwen, meaning Heavenly Questions or Questions to Heaven, written by Qu Yuan, one of the greatest poets of ancient China. In Tianwen, this name conveys the Chinese nation's steady effort in pursuing truth and culture of exploring nature and the universe. CNSA also unveiled (发布) the logo of China's planetary exploration missions, featuring the letter C, signifying China, international cooperation and capacity of entering space.

Tianwen I has flown for 197 days and more than 465 million kilometers on its journey to the planet. It is now around 184 million km from Earth and I. I million km from Mars. Depending on the two planets' orbits, Mars is between 55 and 400 million km from Earth. Mars probe Tianwen I is seen in its first selfies in space on Oct. 1, 2020. The administration also published a black-and-white picture of Mars taken by Tianwen I, the first snapshot (抓拍的照片) from the Chinese craft.

Tianwen I, the country's first independent Mars mission, was launched by a Long March 5 heavy-lift carrier rocket on July 23 from the Wenchang Space Launch Center in Hainan province, kicking off the nation's planetary exploration program.

A successful landing would make China only the second nation to place a spacecraft on the Martian planet. China would also be the first to successfully orbit, land and deploy (部署) a vehicle in the same mission. According to experts, searching for signs of life on Mars will be the first and foremost scientific goal. China is open and inclusive in the development of its space technology not least because it believes that the exploration of outer space should help build a community with a shared future for mankind.
