One day. One lifetime. You can do it! From the museum of modern art to the museum of ancient articles, visit our picks for the world's best museums.

National Gallery of Canada (Ottawa)

    This museum has a great collection of art spanning the Middle Ages to the present day, including American, Indian, European, Inuit and Canadian works. It offers a unique, near-complete overview of Canadian art — from early Quebec religious work, through Inuit work from the 1950s, to the contemporaries.

Tokugawa Art Museum (Japan)

    The Tokugawa family reigned over Japan from 1600 to 1868. Under them, the country enjoyed the longest period of peace in its history. This time span is also known as the Edo period, during which the arts flowered in Japan. Artists of this period directly influenced Western masters such as Monet, Gauguin and Whistler and have since gone on to become household names. Other exhibits effectively present, through accurately reproduced environments, aspects of Japanese life at the time.

    Museum of Fine Arts (Boston)

    Highlights of this museum's collection include a 4th-century Christian marble bust (半身像) of St. Paul at prayer, and a painting that questions life and our very existence, Gauguin's “Where do we come from? What are we? Where are we going?” It's a must — go in the US.

The Egyptian Museum (Cairo)

    As well as gathering together some of the finest archaeological finds from all Egypt, this museum also provides a rare opportunity to simply pop in and within minutes be standing face-to-face with one of the greatest works of mankind, Tutankhamun's golden mask. A portrait of unbelievable quality, craftsmanship and beauty, the highly polished gold face — at once a god, a king and a teenager — shines like water: delicate, yet untouchable all at the same time.

Easy Habits That Help You Live Longer

    Go for a jog

    Among all the things you can do to achieve longevity, one of the most critical is to exercise. Aerobic activity, like running, is important for getting your blood pumping and your heart working. A recent study showed that a one-hour run adds seven hours to your life, up to four hours per week. People who run have a 25 to 40 percent reduced risk of early death, and live about three years longer.

    Get more sun—but not too much

    The “Sunshine vitamin” -vitamin D, that is-has been shown to fight disease, improve bone health, and avoid depression. One study even found it to extend lifespan by 33 percent. But because vitamin D comes from the sun, and our modem lives don't let us spend much time outside, we might not be getting enough. Getting 15 to 30 minutes of sun exposure a day should be enough for vitamin D production.

    Eat more plant protein

    A recent study from Harvard found that people who ate a diet high in processed meats like ham, were at a higher risk of death—but those who got their protein from plants had a lower risk, especially of heart disease-related deaths. The study said that for every three percent increase in calories from plant protein there was a reduction in risk of death by 10 percent.

    Eat nuts

    Although you may think nuts are unhealthy because they are calorically high, the exact opposite is true—they can actually extend your life. A study from Harvard found that daily nut-eaters were 20 percent less likely to die during the study. Specifically, the rates of death from heart and breathing disease were reduced. Other research has shown walnuts have a huge role in heart health because of the amount of antioxidants (抗氧剂）they contain.

    What do you use to unlock your cellphone? A password? A fingerprint? Or simply a glance?

    On September 12, 2017, Apple introduced its iPhone X, which has an eye-catching feature—Face ID.

    With Face ID, Apple says, you can unlock your new iPhone by just looking at it. It is powered by a so-called TrueDepth camera system built into the front of the iPhone X.

    When the camera system sees a person's face, it uses 30,000 unseen dots to “map” the shape and outline of the face. A mathematical model of the face will then be created and stored in the phone.

    The next time the person looks at the iPhone X, the same dots are mapped onto his or her face and compared to the stored model. If the two match, then the phone unlocks. This happens in less than a second.

    Apple says the system is smart. If you change your hairstyle, put on sunglasses or makeup, or use the phone in the dark, Face ID still works.

    Although the technology sounds fancy, there are still concerns. For example, will Face ID work for twins?

    According to Apple, the chance of others to unlock your iPhone X using Face ID is one in a million. Face ID can tell the difference between twins, but the error rating（出错率）rises. So one would need to set a password then.

    Apple also emphasizes that Face ID only unlocks when you stare at it. It is what Apple calls “attention aware”. So the phone won't unlock if you are just glancing at the phone for the time. It won't work either if someone puts the phone at your sleeping face or your photo.

    A new study suggests that people who drank a certain amount of alcohol（酒）had a lower risk of cancer and death than those who drank more or none during a nine-year period. And with each additional drink a week, the risk of cancer and death from any cause increased, the scientists reported.

    However, the study found only an association between alcohol and cancer and death, and did not prove cause and effect, the researches said. What sets the new study apart, said lead study author Andrew Kunzmann, is that previous studies looked at cancer and death separately. “What our study does is combine the two outcomes together and we find that lighter drinking is associated with the lowest risk of cancer or death,” Kunzmann said.

    But Kunzmann noted that the participants（参与者）were all older adults. That means that “we're not really showing what happens in younger people if they drink,” he said. Also, it's difficult to account for other lifestyles that could have affected the results. “These could also influence health. But the results did take into consideration differences in diet, smoking and education among participants,” Kunzmann noted.

    The researchers said that they hope their study sparks conversation about reducing the suggested alcohol intake in countries' guidelines. “We're not telling people what they can or can't do or what they can or can't drink,” Kunzmann said. “We're just trying to give them reliable evidence so that they can make their own informed, healthy decisions.”

    One day after school, I went to the teacher's office to see my teacher, but nobody was there. As I was about to leave, I noticed a piece of paper on the floor. I picked it up and saw the words "FINAL-TERM EXAMINATION" at the top. I put the paper into my school bag secretly and ran out of the room.

    After I came back home, I took out the paper quickly. It was the exam paper of my worst subject, History. I felt excited. My heart beat fast. I took out my History book and started working on the answer. I had never answered any questions so seriously.

On the day of the History exam, I went into the exam hall confidently. When the paper was sent to me, I dreamt of getting the highest mark in the whole grade and could not help smiling. "My History teacher always encouraged me to work hard and get better grades, but I let him down time and time again. This time I will give him a big surprise," I thought.

    When the teacher said we could start, I turned the paper over. To my great surprise, all the questions were different. Later I felt nervous. In the end, I almost left the paper undone. After the exam. I ran to the toilet, took out the paper and carefully read it from the top. Oh! It was last year's exam paper. I read all the questions but I hadn't read the date.

    This is a lesson in which I know I have to put my feet on the ground. I regretted doing such a silly thing. After that, I told my teacher the truth and I promised to be honest. From then on, I worked harder than ever before.
