Polar bears are suffering in a {#blank#}1{#/blank#} (warm) world.

    Polar bears live in environments too cold for most animals. {#blank#}2{#/blank#} much of the year, they live and hunt on the frozen Arctic sea ice. Nature has prepared {#blank#}3{#/blank#} for the cold conditions. But nothing has prepared the bears for the danger that {#blank#}4{#/blank#} (threat)the only home they know.

    The polar bears' world is melting. Studies show that the polar ice has reduced by 9.8% every 10 years {#blank#}5{#/blank#} 1978. Now about 20,000 to 25,000 polar bears live in the Arctic. Polar bears depend on the sea ice for their {#blank#}6{#/blank#}． (survive). “The sea ice is more than just this platform that the bears walk over,” says Andrew Derocher, {#blank#}7{#/blank#} scientist who studies North American polar bear populations. “{#blank#}8{#/blank#}  it, they can't exist.”

    Some melting and refreezing of the polar ice is natural. {#blank#}9{#/blank#} in a warmer world, these cycles speed up, and bears have less time to hunt. Normally, they have three months in the spring when they gain more weight. The extra fat is used later, {#blank#}10{#/blank#} the bears are not actively hunting.

    When I was 13, my journey in a great valley changed my attitude towards the recording of a travel. During the trip, I was busy recording every event, name and place I came across. I felt proud to {#blank#}1{#/blank#} my time, keeping a {#blank#}2{#/blank#}description of my travels. On my last night there, after I {#blank#}3{#/blank#} the tent, I went out with diary in hand. The sky was clear with the bright moon, and the walls of the valley looked frightening behind their curtains of shadows（阴影）. The beauty of nature at dusk {#blank#}4{#/blank#} my heart entirely. I took out my pen right away... At that moment, I understood that the beautiful scenery I saw {#blank#}5{#/blank#} was more meaningful than the tiring words that I had {#blank#}6{#/blank#} in my diary. Since then I have {#blank#}7{#/blank#} only to keep a special thought or feeling in my diary. The unforgettable moments I {#blank#}8{#/blank#} would be the sweet and lasting memories for my life.

    To celebrate the Lantern Festival the Palace Museum organized its first light show in the Forbidden City.

    The complex, home to Chinese emperors for five {#blank#}1{#/blank#}(century), was opened at night for the first time in 94 years. It was lit up with giant red lanterns and projections of ancient paintings. Masterpieces such as Along the River During the Qingming Festival were projected on the roofs, giving visitors a feeling like walking {#blank#}2{#/blank#} time. The design team smartly combined high technology{#blank#}3{#/blank#}(light) with the principles of cultural relic preservation.

    Only 3, 000 people {#blank#}4{#/blank#}(allow) in on that day: 500 people who booked their tickets online, and 2, 500{#blank#}5{#/blank#}(invite) guests including model workers, officers, soldiers, and ambassadors.

    With{#blank#}6{#/blank#} series of well-planned and tourist-friendly cultural activities, the Palace Museum is now on a campaign to make traditional Chinese culture more {#blank#}7{#/blank#}(access) to the general public. It has set an example to other museums in our country, most of {#blank#}8{#/blank#} seem to be still living in days gone by. Hopefully, the handsome turnover will be used{#blank#}9{#/blank#}(appropriate) to better protect the Forbidden City and improve {#blank#}10{#/blank#}(it)international image of being part of the world's cultural heritage.

    For Nigel Portman, a love of travelling began with what's called a "gap year". In common with many other British teenagers, he chose{#blank#}1{#/blank#}（take） a year out before settling down to study for his degree. After doing various{#blank#}2{#/blank#} （job） to raise some money,  he left home to gain some experience of life in different cultures, visiting America and Asia. The more adventurous a young person, the{#blank#}3{#/blank#}（great） challenge they are likely to set{#blank#}4{#/blank#}（them） for the gap year, and for some, like Nigel, it can result in a thirst for adventure.

    Now that his university course{#blank#}5{#/blank#}（come） to an end, Nigel is just about to leave on a three﹣year trip that will take him right around the world. What's more, he plans to make the whole journey{#blank#}6{#/blank#}（use） only means of transport which are powered by natural energy. In other words, he'll be relying{#blank#}7{#/blank#}（main） on bicycles and his own legs; and when there's an ocean to cross, he won't be taking a shortcut（捷径）{#blank#}8{#/blank#}flying aboard﹣he'll be joining the crew of a sailing ship, instead.

    As well as doing some mountain climbing along {#blank#}9{#/blank#}way, Nigel hopes to pass on to the people he meets the environmental message {#blank#}10{#/blank#}lies behind the whole idea.

    When it comes to climate change, language does count. In March, the Guardian changed{#blank#}1{#/blank#}(it) wording – using "global heating" instead of "global warming" , after scientists found that Earth's temperature is set {#blank#}2{#/blank#}(rise) from between 2.5C and 4.5C. And on May 1, the UK parliament declared a "climate emergency", {#blank#}3{#/blank#}(become)the first parliament to do so.

    If with "global warming", we're still inside our comfort zone of handling the situation, entering the state of "global heating" is like heading to a point {#blank#}4{#/blank#} the delicate balance of nature is disturbed so much that there is no turning back. Everything will be changing: Coral will die, polar bears will lose their habitats completely, and extreme{#blank#}5{#/blank#} (weather) like droughts and heavy storms will happen at a higher{#blank#}6{#/blank#} (frequent). There is no denying that we're entering a climate emergency.

    Decades ago when the science on the climate issue was first increasing, the impacts could be seen as an issue for future generations," but now it's {#blank#}7{#/blank#}(definite) our issue, {#blank#}8{#/blank#}shift we all are living together.

    However, getting these messages {#blank#}9{#/blank#} is far from enough. It depends on each to find a solution – if there are any solutions left to find. The UK's Labor leader Jeremy urged that "we {#blank#}10{#/blank#}(take) rapid and dramatic action now".

    Indeed, language matters. But action matters even more.
