Iman, the last Sumatran rhino(犀牛) in Malaysia, died in 2019 — bringing the endangered species one step closer to extinction. Now, Malaysian scientists are hoping to use tissues and cells from Iman and other dead rhinos to bring the population back.

"Before the three rhinos (the last survivors in Malaysia) died, we got their cells, and the cells are still alive — which is why I'm quite confident," Dr. Lokman said. "If we don't have any cells, or have just tissue that isn't living anymore, we wouldn't be able to do anything. But now we have a living thing that we can use. "

The cells came from the rhinos'hearts, lungs and brains. What is the most important is that the team collected stem cells (干细胞). One possible approach is to develop these stem cells into an egg (卵子) and sperm (精子), to create an embryo (胚胎) that will be placed into a surrogate mother (代孕母亲). She will likely be another rhino, either a Sumatran rhino from another country or another species. The other method is to take the egg of a surrogate animal, remove the nucleus (细胞核), and join it with a Sumatran rhino's body cell. This technique was famously used to clone Dolly the sheep in 1996. Dr. Lokman and his colleagues are trying both ways. The team is still in the early stages; next, they need to find a suitable surrogate female.

Sumatran rhinos are listed as critically endangered by the World Wildlife Fund. There are less than 80 alive in Indonesia and Thailand. The fall in the population was first caused by hunting. Later, the situation was worsened by the loss of habitats and human activity. Unfortunately, there are now only five remaining rhino species worldwide, and all are threatened. Some sub-species have already died out; the western black rhino was declared extinct in 2013. And it is a pity that the last male northern white rhino died in 2019.

(1)、What makes it possible for the team to bring the Sumatran rhinos population back?
A、They have collected three rhinos living cells. B、They have carried out similar experiments before. C、There is a baby Sumatran rhino living in Malaysia. D、There are still some cells alive in the dying rhino.
(2)、What do the two methods have in common?
A、Both have been used for Dolly. B、Both change the cell's nucleus. C、Both involve a surrogate female. D、Both rely on the Sumatran rhinos' stem cells.
(3)、What feeling does the author express in the last paragraph?
A、Her admiration for cloning technology. B、Her satisfaction with the scientists' efforts. C、Her disappointment at protection measures. D、Her deep worry about the rhino population.
(4)、What's the main idea of the passage?
A、Last Sumatran rhino in Malaysia has died. B、Scientists hope to clone Sumatran rhinos. C、Stem cells are giving birth to new rhino babies. D、Sumatran rhinos are listed as critically endangered.

    I believe that my country,Poland,is a perfect example for a place where food is particularly important. When we were little children, we began to understand how much a loaf of bread meant to our parents—to some it might sound silly but for me the custom of kissing bread before you started cutting it was simply amazing. It's not so common nowadays to treat food that way,since you hardly ever bake your own bread. Besides, everyone would call you crazy if you tried to kiss every bread roll before you ate them! But though we no longer make our food from scratch (起点), some customs have been kept—that's why I feel so sorry every time I have to throw any food away—even though I no longer live with my parents and nobody would blame me for this anymore!

    Many people of our nation are still working as farmers, eating what they grow and harvest and therefore enjoying everything more. It's widely known that you value more anything that needs your effort in the first place. In most homes in Poland, especially those of farmers, the whole family would try and have their meals together—extremely difficult now, but so rewarding! You can share other members' troubles and successes, give your children some attention, or just sit down for a moment, instead of rushing through life aimlessly. Furthermore, your body,and stomach in particular will be very grateful for such a time!

    In Poland, a wedding,Christmas or even a birthday is celebrated with a great meal. Women in the house get together and cook ,sometimes for a few days before the event,and the extremely good or unusual food will be remembered and widely talked about.

    You cannot over-value the importance of food in the country. What's more, almost everyone in Poland will be as interested in the topic as I am.

    After finishing my teaching for a school year, I thought that I should go back to Montreal, Quebec, my hometown for a visit. My main goal was to relax in preparation for the challenges of my retirement in the coming year.

    Through my stay in Montreal, I met lots of Chinese who are struggling to succeed and then lead a better life in Canada.

    Some travelled thousands of miles to get knowledge. When I spoke with some of them about the major barrier they had to face after they arrived in Canada, they all talked about the two official languages of Canada. But I was impressed by their ability to express their ideas while switching between English and French.

    Almost all of those people said they often felt homesick. They miss their families and friends. Though Montreal has lots of Chinese restaurants, they long for a home-cooked meal.

    I met some tourists who were trying to realize their childhood dreams of experiencing the life in a developed country. When I asked them if Montreal had lived up to their expectations, they hesitated. They said that reality never agrees with fantasies. However, they were glad to have the opportunity to visit Montreal and didn't regret taking the trip.

    Not all the Chinese people I met were happy. I once met a young lady who met with a gentleman through the Internet. However, to her disappointment, he disappeared after he promised to marry her in Montreal.

    I was served by another Chinese person who could not handle the challenges of studying in an English environment and ended up working in a restaurant with minimum pay.

    Exploring different parts of the world, without any doubt, is an amazing experience. However, one should be realistic when it comes to leaving his hometown to set up a new life in a foreign country. One should take the time to examine the advantages and the shortcomings of the venture before they decide to chase an uncertain dream of achieving success or leading a better life.

     “Oh, my god. Are you serious?”

    That's a reaction I often get when people hear the tale of my childhood.

    It's a story I don't often share. Growing up in a bad home, I learned to protect myself by not speaking up. I've seldom said anything about how badly I was treated and hurt as a child.

    I don't talk about how my name was changed at least three times, what it was like to live in my van (箱式货车), or how I've struggled with anxiety, depression and wanting to kill myself.

    But I learnt to start speaking up for myself. I went on to earn two graduate degrees and I will complete my doctorate (博士学位) this year. I've also become a widely published author. So, how did I get to where I am today?

     What's helped me is surrounding myself with caring, loving people. I've learned day-to-day skills through research, trial and error, and with the help of skilled professionals.

    They've taught me how to slow down, to breathe, to be thankful for what I've got. They're the ones who make my goals possible. They have also taught me to turn my past experiences into strength—to make the negatives into positives.

    My hope is that sharing my story might help others to see what is possible even in the darkest of times and help others to speak out.

    I don't think I'm in any way special or unique. I'm a common man, no more deserving than anyone else. But for far too long, I've been afraid that others think I'm damaged goods. I've worried about how I might be treated differently.

    Pain and fear teach us to be silent. It's time for that to change.

    I don't know what tomorrow might bring. But one thing I've learned is that if we can hold on and find help, if we find ways to get through the day and speak up, we'll not only survive, but become stronger than before.

    Our very survival can be an inspiration all on its own. And with love of my friends, I look forward to so much more than completing my education – I look forward to the future.

    British English may have come first, but around the world, the American way of spelling is now far more popular.

    A recent examination of the English language shows that publications now largely use the American version swapping words like “centre” for “center” after the 1880s. To get data, researchers used Google's Ngram Viewer to analyze the words found in all English-language publications from 1800 to 2000. Entering a word into the viewer will show how frequently it occurs within the massive corpus(语料库)of books around the world.

    According to the data, this shift was further strengthened around World War I. Since then, English-language publications have preferred “gray” and “flavor” instead of “grey” and “flavour”. The American spelling has continued to grow over the years, with “liter” passing “liter” around 1900, and “center” becoming the more common choice over “centre” in 1913. “1913 marked a turning point in British spelling, as the American alternative became more frequently used in literature,” the post explains, in regard to “center”. This was just a year before the beginning of World War I, which many views as a key period in America's rise to superpower status.

    Though this switched again between 1920s and the late 1930s, the American, spelling took over for good around 1940, during which time the spelling “airplane” shifted dramatically over “aeroplane”.

    Ever since the middle of the 19th century, even the British Isles have slowly rejected the old spelling. The future is gray for British English.

    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.
