BEIJING—The sky is gray and air smells strange．It's another day of smog．On Saturday，heavy haze (霾) still covered north and east China．Highways were closed and1 couldn't take off on time．

    The smoggy weather 2 the country's land from north to south，including Beijing, Hebei， Shandong，and 60ther provinces．People could only see clearly 3 than 50 meters in some areas．

    Cities 4 Shanghai and Nanjing have been covered by the gray sky for the past several days．Many walkers in the street had to wear 5 ． In the Lukou airport in Nanjing more than 60 flights were canceled on Saturday 6 the haze，which also made primary and middle schools and kindergartens stop 7on Thursday and Friday in Nanjing．

    The office worker of Environmental Protection said earlier this week that there were several 8 reasons behind the widespread haze：unpleasant weather conditions making9 difficult for smog to disappear，automobile exhaust(尾气)，and coal use for winter heating．

    To fight pollution，the Chinese government now plans to clean up the air by cutting coal use，10 some factories，and removing 6 million old cars from the roads．

     “We must face up to the facts，”said Yan Naiqiang，a professor of environmental science at Shanghai Jiao Tong University．“The treatment of smog will be a long fight． From now on，if we use buses or cars less and do more tidin9，we believe a clear sky is not a faraway dream．”

    Natural resources that we use are things that come from the Earth.

    Our natural resources are limited(有限的）. This means that they will not1 forever. Some are renewable, like when you plant a new tree when you2 one down. Others are not renewable, like when you dig coal(煤）out of the3. Once it is used, it is gone.

    People realize the4 that the Earth's natural resources are limited, and people can do things to help conserve(节约）those resources. 5 you try to conserve a natural resource, you try to use less of it so it does not run out so 6One way that people conserve fuel, like gasoline, is by riding a bicycle or walking when the 7 is short instead of driving everywhere.

    Water is a very important natural resource because we all need it to stay 8. We can conserve water9 making sure that the pipes and taps do not leak(漏）. We can also make10 choices to conserve water, like only using the dishwasher or washing machine when they are full. Everyone can make contribution to protecting natural resources.

    A great way to limit(限制) your impact(影响) on the planet is to follow other animals' way of eating. Squirrels（松鼠）, 1, eat nuts close to their tree houses. Elephants eat trees or plants that 2 around. What these animals are doing is eating in season and locally. We can do the same.

    Most of our favourite fruit and vegetables have their own natural seasons. Modern farming techniques make it 3 for us to eat all kinds of things any time of the year. However, 4 we eat our food in their natural seasons, we will save more energy.

    Eating locally means eating things that are grown close to your home. It will lower the impact that you and your eating 5 have on the environment. An easy way to 6 local produce is to shop at a nearby farmer's market.

    One of the best things you can do is to grow your own food. It may seem like a lot of 7but people and communities all over the country grow some or all of their own food.

    There are many 8 to grow your own food. By doing this, you can 9 where your food comes from. Besides, you can make sure that your food is fresher. It can 10 weeks for the food to get from the farm to the supermarket.

    By growing your own food, those weeks become just days, hours or even seconds. Now that's fresh!

    Do you often drink bottled drinks? Of course 1  is so cool to get a cold one right out of the fridge, right? But all those plastic bottles use a lot of oil and  2 the environment. Americans buy 3 bottled water than any other nation in the world. In order to make all these bottles, 17 million barrels (桶) of oil  4up. That's enough oil to keep a million cars going for twelve months.

    Many people choose 5 the bottles away after having the bottled drinks. In fact, instead of going out with the trash, plastic bottles can be turned into carpeting for clothing. Remember this: Recycling one plastic bottle  6save enough energy to power a 60-watt light bulb for six hours.7 , for every six water bottles we use, only one is recycled. The rest are sent as garbage (垃圾). Or, even worse, they end up 8  trash on the land or in rivers and oceans.

    So why don't more people drink water from the kitchen? Some people drink bottled water 9 they think it is better for them, but that's not true. The chemicals in the bottles themselves may get into the water which can do harm to people.

    So next time when you have drinks or water, please  10 to use a glass at home or carry water in a steel bottle. And if you want to do something more, try to collect plastic bottles and send them for recycling.

The fear of the novel coronavirus（新冠病毒） has turned into discrimination (歧视) against certain groups of people, {#blank#}1{#/blank#}(include) people from Wuhan, Chinese people or Asians in general. However, the outbreak of the disease can't be an excuse to isolate these groups. What we should do is {#blank#}2{#/blank#}(get) rid of (消除) discrimination and show sympathy (同情) instead.

Since the outbreak of novel coronavirus pneumonia (NCP), many people {#blank#}3{#/blank#}(live) in fear. This is normal, as the disease is infectious (传染性的) and dangerous. However, some people turn pale at the mention of "people from Wuhan or Hubei province", the center of the outbreak.

    Ding Baixing, a doctor at Huashan Hospital in Shanghai, has seen this himself. He treated a suspected (疑似的) patient {#blank#}4{#/blank#}(name)Chen Hui who traveled from Wuhan to Shanghai. Chen appeared desperate (绝望的) and avoided {#blank#}5{#/blank#}(keep)in touch with other patients, as he worried that they would be afraid of him.

    Chen is not alone. Chen Xue, an editor {#blank#}6{#/blank#}(work) in Beijing, went to Chongli in Hebei for a ski trip on Jan 23. Though her temperature was fine and she hasn't been to her hometown – Hubei province – since October last year, the hotel she was in told her that it {#blank#}7{#/blank#}(will not) receive Hubei guests from the next day.

    However, the real enemy is the virus – not the patients or people from Wuhan or Hubei province. Singaporean Prime Minister Lee Hsien Loong echoed this idea in a speech at the Chinese New Year dinner. "Even though the virus started in Wuhan, it doesn't respect nationality or race (种族). It does not check your passport (护照) before it goes into your body. Anybody can be infected," he said.

    It is not the {#blank#}8{#/blank#}(patient) fault that they have been infected. There is no reason to blame them. If patients didn't go to the hospital for fear of discrimination, the virus {#blank#}9{#/blank#}(spread) to more people. "Protecting them is just as important as protecting ourselves," Ding said. 

Poem that inspires

At the CCTV Spring Festival Gala (春节联欢晚会), six hosts read a poem to inspire people across the country. It called for greater respect for medical workers, as well as called on everyone to work together to fight the virus. One of the lines – "we isolate (隔离) the virus, but we don't isolate love" – has been {#blank#}10{#/blank#}(wide) posted online.
