In one of the world's most forbidding environments, Polar bears spend !heir summers roaming (漫步) the Arctic on large pieces of floating ice. They drift(漂移) for hundreds of miles, finding mates, hunting for seals , and fatting themselves up for the winter. Without the floating ice , the world's largest bears could not survive Yet at this moment , the polar bears' Arctic habitat (栖息地) is melting away under it because of global warming.

    Over the past three decades, more than a million square miles of floating ice has disappeared Scientists predict that, if the current rate of global warming continues, most, if not all, of the bears' floating ice will be gone by 2100. As a result, the world's polar bears could face global dying out by the end of this century.

    Already, the ice on the southern edge of the polar bears' habitat is melting about three weeks earlier than in the past. The loss of those key weeks leaves the bears less time to hunt, eat and store up fat. Once the ice melts, the bears must fast for up to eight months on land until the floating ice returns. As a result of early melting, there has been a 14 percent decline in the Hudson Bay polar bear population over the past ten years- a fall clearly caused by global warming.

    Besides, a growing number of polar bears may be drowning (溺水) as they are forced to swim more often, and for longer distances, looking for ice sheets(冰原). According to a report by the US Mincrals Management Service, researchers observed four dead polar bears floating 60miles off Alaska in September of2006 and said it was likely that many other bears swimming far off shore also drowned. Scientists have concluded that the worldwide population of about 20,000polar bears is likely to become smaller by more than 30 percent in the next 35 to 50 years alone.

    Every pet owner loves his pet. There is no argument here.

    But when we asked our readers whether they would clone their beloved animals, the responses were split almost down the middle. Of the 228 readers who answered it, 108 would lone, 111 would not and nine weighed each side without offering an opinion.

    Clearly, from readers' response, this is an issue that reaches deeply into both the joy and eventual sadness of owning a pet. It speaks, as well, to people's widely differing expectations over the developing scientific procedure.

    Most of the respondents who favored the idea strongly believed it would produce at least a close copy of the original; many felt the process would actually return an exact copy. Those on the other side, however, held little hope a clone could never truly recreate a pet, many simply didn't wish to go against the natural law of life and death.

    Both sides expressed equal love for their animals. More than a few respondents owned “the t dog/cat in the World”. They thought of their pets as their “best friend”, ''a member of the family,” “the light of my life.” They told moving stories of pets' heroism, intelligence and selfless devotion.

Little wonders the loss is so disturbing—and the cloning so attractive. “People become very lose to their animals, and the loss can be just as hard to bear as when a friend or family member dies,” says Gary Kowalski, author of Goodbye, Friend: Healing Wisdom for Anyone Who Has Ever Lost a Pet. “For me, cloning feels like an attempt to turn death away... It's understandable. Death is always painful. It's difficult to deal with. It's hard to accept.”

    But would cloning reduce the blow? This question seemed to be at the heart of this problem.

    Jack threw the papers on my desk. “Next time you want to change anything, ask me first,” he said. I had changed a long sentence and corrected its grammar — something I thought I was paid to do.

    Several days later, he made me angry again. I went to his office, prepared to lose my job if need be, but not before I let the man know how I felt. “What?” he said nervously.

    Suddenly I knew what I had to do. “Jack, the way you've been treating me is wrong. And it's wrong for me to allow it to continue,” I said. “I want to make you a promise. I will be a friend.” The next day I brought some cakes to Jack's office. Every time I saw Jack in the hall, I smiled at him. After all, that's what friends do.

    One year after our talk, I was told that I had breast cancer . When I was in hospital, my friends tried to find the right words to say, but no one could. The last day of my hospital stay, the door opened and Jack walked over to my bed. “Tulips (郁金香),” he placed some bulbs  beside me and said, “If you plant them when you get home, you'll be there to see them when they come up.” Tears filled my eyes.

    In a moment when I prayed for just the right words, a man with few words said the right thing. After all, that's what friends do. Now, I have seen those tulips push through the soil every spring for over ten years.

    Hey, ladies! It's summer again and it's time for a new you! No more make-up, no more pretending! Yes, that's right! It's time to stop making ourselves beautiful for the camera, and start posting confident pictures without all the make-up and extra tricks we add onto ourselves in the hope of appearing more attractive and beautiful. Because believe it or not, we already are!

    After we wash our face and go to bed, it is not so perfect. You know it the face we should confidently be showing to the world! Who cares if you have pimples（面痕）or your eyes look small, or if you have crow's feet? Guess what? Those are actually what make you such a beautifully grown woman. And any person who doesn't think so is just not as strong as you.

    Nowadays we are so prone to do anything and everything to make us look as young and perfect as possible. Yet the truth is, by doing this, we are actually making our tree skin get worse and badly affected by all the junk we put on. We are making ourselves believe that by changing our appearance we will be more accepted and seem more attractive to other people. And yet, our final goal is to find that without all of the make-up. What kind of twisted（扭曲的）game are we really playing with ourselves?

    So I would like to make a suggestion for all women out there to give yourself a break at least this summer. Take a couple of pictures without all of that make-up on. You don't need it every single day, especially not this hot summer! You'll be surprised that the more confident you are about showing the real side of you, the more attractive you will be to everyone else.

    Yes, the saying, “Beauty comes from within” is an old one, definitely still holds some troth today. So be brave, carefree, and make-up free! Let the world see you for who you really are!

    The University of Tokyo has eight museums covering various fields such as medicine, agriculture and art. Click the names of the museums below to read brief introductions about their histories and exhibits.

    The University Museum

    Having accumulated over three million academic materials for its collection since the University of Tokyo was founded in 1877, the University Museum is the largest museum of its kind in Japan. From the time of its reorganization into an independent entity in May 1996, the Museum has held exhibitions over 60 times.

    The Museum of Health and Medicine

    The Museum of Health and Medicine seeks to provide information about health and medicine to the general public and advance education for students studying medicine. The Museum features both a permanent and a temporary exhibition space and a temporary exhibition space, with the latter focusing on topics related to medical care and the study of medicine.

    The Agricultural Museum

    The Agricultural Museum displays materials from the collection of the University's Graduate School of Agricultural and Life Science, Notable items on display include the documents and portraits of scientists affiliated (隶属的)with the University, internal organs of Japan's famous dog Hachiko, and drawings illustrating German agriculture and the varieties of Japanese cows.

    The Farm Museum

    The Farm Museum opened in 2007 within a renovated dairy bam. The bam was built in 1934 as part of the moving of the University of Tokyo's farm from Komaba to Tanashi, an area in Western Tokyo. The Museum features both permanent and temporary exhibitions. Permanent exhibitions include European farming equipment used on the Komaba Farm, tools for agricultural experiments, agricultural machinery, American tractors and drawings illustrating German agriculture.

Are you a moviegoer? If, like me, you're a fan of film, then there's no better place to watch something than on the big screen at the cinema. You enter the dark theatre and take your seat, ready to be entertained. But while you are absorbed in some movie magic, many others are now getting their film fixed at home.

Over the last few years, cinemas have seen a comeback. Customers have been attracted by comfortable seats, and lots of choice of things to watch. Multiplexes in particular can screen up to twenty films at the same time, suiting all different tastes. In addition, 3D and even 4D movies can give the audience an extra immersive experience. So what's not to like about a trip to the cinema?

The coronavirus pandemic has put the future of cinema under the spotlight. Some have had to close because of reduced ticket sales. In the UK, it's brought about a surge in TV watching and online streaming. It's reported that half of UK adults will keep and continue using their new streaming subscriptions.

This isn't great news for cinemas. They rely on the release of a big blockbuster to bring the crowds back, but the launch of new films, such as James Bond: No Time To Die, are being delayed. Disney has released its $200m blockbuster, Mulan, online instead of in movie theatres. John Fithian, from the National Association of Theatre Owners, told Variety magazine: This idea of waiting out the pandemic to make your movies more profitable doesn't make sense to me. There won't be as much of an industry left to play your movies in if you do that. "
