    A Chinese scientist's attempt to produce the world's first gene-edited babies who are immune to HIV has caused floods concern.

    In an online video posted on Monday, He Jiankui, a biological researcher, announced that a pair of twin baby girls, Lulu and Nana, was born healthy a few weeks ago with genetic editing technology that can prevent them from being infected with HIV.

    He, who was believed to be in Hong Kong on Monday to attend the Second International Summit on Human Genome Editing, could not be reached for comment. But his announcement sparked a heated argument concarning medical ethics(伦理)and effectiveness.

    The Shenzhen Health and Family Planning Commission said on Monday evening that it had not received any ethical assessment application for the study, which is required as a prior condition for such experiments.

    More than 120 scholars from universities and institutes with high status from China and abroad,such as Tsinghua University and the Massachusetts Institute of Technology (MIT),strongly condemned the research in a signed statement, saying the “research” lacks effective ethics inspection, and it amounts to human experimentation,which is “crazy”.

    In the statement, published on Sina Weibo, the scientists said any attempt to make changes to human embryos with genetic editing and give birth to such babies involves high risk as an inevitable part, due to inaccuracies in existing genetic editing technologies.

    “Scientists all over the world dare not make such attempts due to the huge risks and more importantly, ethics. The government must make quick legal moves to strictly supervise(监督)such research. The Pandora's Box has been opened, and we may still have a chance of closing it before it is too late,”the statement said.

    Tsui Lap-chee, president of the Academy of Sciences of Hong Kong, said a lot of issues may occur in gene editing. If one gene is edited, it will affect others that interact with it. And the whole genome, a collection of genes, may also be affected.

(1)、Scientists compare baby gene-editing experimentation to Pandora's Box mainly because ______.
A、existing genetic editing technologies are not accurate enough B、the baby gene editing experimentation is likely to cause huge risks C、genetic editing technologies may have a bad influence on the whole genome D、it is crazy for scientists to do the gene-editing experiment without permission
(2)、It can be inferred from the passage that ____.
A、it is too late for the Chinese government to take any effective measure B、He Jiankai didn't apply for ethical assessment before conducting the research C、Sina Weibo didn't approve of such research due to the consequence of high risk D、MIT doesn't have strict supervision in the research as to genetic editing technology
(3)、What is the best title for the passage?
A、Newly-born gene-edited babies are on the way B、A breakthrough in Human Genome Editing is made C、A pioneer in genetic editing technology receives credit D、Birth of gene-edited babies causes widespread concern

    Long Beach, a 28-mile area of beach, lies in southwestern Washington, and is generally called Long Beach Peninsula. Communities there take you back to old days of a simple life. Here, visitors can relax and enjoy the good of a total rest.

    Bird watching

    There are different kinds of birds on Long Beach. It's best if you watch them from a distance and don't try to frighten them. The Southwest Loop Route Map can be got through the Long Beach Peninsula Visitors Office by calling 1-800-451-2542.

    Horses

    A popular activity on Long Beach is horseback riding. Two businesses in the city of Long Beach offer guided horseback tours along the beach: Black Country Wilderness Outfitters and Skipper's Equestrian Center. You may also bring your own horse. Among the adventures offered with horses is a wagon(四轮马车)ride along the beach, a carriage ride through Seaview or Long Beach, a back country pack trip, or a sunset ride by horseback on the beach.

    Camping

    RV(活动房屋式旅游车)and tent camping aren't allowed on the beach. Camp fires are allowed within 100 feet off the beach, but must be away from the dry grass.

    Swimming and other activities

    Swimming is allowed, but you must be careful. The waters are very cold and dangerous. Surfing(冲浪)is advised only for experienced surfers. Beach driving is allowed at certain areas on the beach. The speed limit is 25 mph. Building sand castles, digging sand to find something, riding bicycles and flying kites are also popular activities in the area.

    Enjoy your trip to Long Beach, Washington!

    Sunday is more like Monday than it used to be. Places of business that used to keep daytime“business hours” are now open late into the night. And on the Internet, the hour of the day and the day of the week have become irrelevant(不相关的). A half century ago in the United States, most people experienced strong and precise dividing lines between days of rest and days of work, school time and summer time. Today the boundaries still exist, but they seem not clear.

    The law in almost all states used to require stores to close on Sunday; in most, it no longer does. It used to keep the schools open in all seasons except summer; in most, it still does. And whether the work week should strengthen its legal limits, or whether it should become more “flexible,” is often debated. How should we, as a society, organize our time? Should we go even further in relaxing the boundaries of time until we live in a world in which every minute is much like every other?

    These are not easy questions even to ask. Part of the difficulty is that we rarely recognize the “law of time” even when we meet it face to face. We know as children that we have to attend school a certain number of hours, a certain number of days, a certain number of years — but unless we meet the truant officer (学监), we may well think that we should go to school due to social custom and parents' demand rather than to the law. As adults we are familiar with “extra pay for overtime working,” but less familiar with the fact that what constitutes(构成)“overtime” is a matter of legal definition. When we turn the clock forward to start daylight-saving time, have we ever thought to ourselves: “Here is the law in action”? As we shall see, there is a lot of law that has great influence on how we organize and use time: compulsory education law, overtime law, and daylight-saving law — as well as law about Sunday closing, holidays, being late to work, time zones, and so on. Once we begin to look for it, we will have no trouble finding a law of time to examine and assess.

    The popular wisdom for years has been that drinking in moderation (适度)—that's one “standard” drink a day for women and two for men-is linked to a lower risk of cardiovascular (心血管的) disease. But recent studies are casting some doubt on that long-held learning. Science now says it depends on your age and drinking habits.

    A 2017 study of nearly 2 million British with no cardiovascular risk found that there was still a modest benefit in moderate drinking, especially for women over 55 who drank five drinks a week. Why that age? Alcohol can influence the substance in the blood in positive ways, experts say, and that's about the age when heart problems begin to occur.

    Also, a 2018 study found that drinking more than 100 grams of alcohol per week—equal to roughly seven standard drinks in the United States or five to six glasses of wine in the UK—increases your risk of death from all causes and in turn lowers your life expectancy. Links were found with different forms of cardiovascular disease, with people who drank more than 100 grams per week having a higher risk of stroke, heart failure.

    Another 2018 study found that consistently drinking a moderate amount of alcohol, within recommended guidelines, had a protective effect on the heart over time. Unstable drinking habits were associated with a higher risk of heart disease, which the authors reflected might indicate broader lifestyle changes, such as poor health or stress. Former drinkers were also at greater risk.

    Overall, however, the latest thinking is that any heart benefit may be outweighed by other health risks, such as high blood pressure, certain cancers and liver damage.

Women who drink are at a higher risk for breast cancer; alcohol contributes about 6% of the overall risk, possibly because it raises certain dangerous hormones in the blood. Drinking can also increase the chance you might develop liver, mouth and oral cancers. One potential reason: Alcohol weakens our immune systems, making us more likely to inflame (发炎)—a driving force behind cancer.

It's generally believed that people act the way they do because of their personalities and attitudes .They recycle their garbage because the care about the environment .They pay $5 for a caramel brulée latte because they like expensive coffee drinks.

It's undeniable that behavior comes from our inner dispositions (性情), but in many instances we also draw inferences about who we are, as suggested by the social psychologist Daryl Bem , by observing our own behavior .We can be strangers to ourselves .If we knew our own minds, why would we need to guess what our preferences are from our behavior? If our minds were an open book, we would know exactly how much we care about the environment or like lattes .Actually, we often need to look to our behavior to figure out who we are.

Moreover, we don't just use our behavior to learn about our particular types of character—we infer characters that weren't there before .Our behavior is often shaped by little pressures around us, which we fail to recognize .Maybe we recycle because our wives and neighbors would disapprove if we didn't .Maybe we buy lattes in order to impress the people around us .We should not mistakenly believe that we always behave as a result of some inner disposition.

Whatever pressures there can be or inferences one can make, people become what they do, though it may not be in compliance (符合) with their true desires .Therefore, we should all bear in mind Kurt Vonnegut's advice: "We are what we pretend to be, so we must be careful about what we pretend to be."

Minu Pauline is the owner of Pappadavada Restaurant in Kochi, India. Late one night, as she watched a homeless woman searching through the garbage bin outside her house, a realization hit her with full force—she had been abandoning perfectly good leftover food while someone in need was looking for food.

Touched by this sad sight, Pauline knew she had to find a solution to this problem. That woman had been sleeping and was woken up by her hunger, so she had to go in search of food instead of sleeping.

Inspired by her desire to make a difference, she decided to take action. The idea was simple but mighty: She placed a refrigerator at the entrance of her restaurant, stored with leftover food that anyone could take for free. This refrigerator became a beacon (灯塔) of hope for the hungry and the homeless.

Each day, Pauline fills the refrigerator with 75 to 80 packets of leftovers, carefully labeling each one with the date it was cooked. And there are days when she goes above and beyond, putting in 100 packets to ensure no one leaves hungry. The self-service refrigerator is open 24 hours a day, 7 days a week, allowing anyone in need to access a warm meal whenever they require it. It's about recognizing the value of resources and combating food waste.

In an interview with The Huffington Post, she passionately emphasized that while money may belong to individuals, resources are a communal asset. She believes that wasting resources, especially food, is not only a loss for individuals but also a disservice to society as a whole.

Through her selfless act, Pauline has sparked a ripple (涟漪) of kindness and compassion in her community.
