You may like at least some kind of music. But the problem is that, in lots of places, you're made {#blank#}1{#/blank#}(hear) somebody else's choice of music. Say you've just landed at an airport, where the background (背景) music may be played loudly. When you are {#blank#}2{#/blank#} the way to you hotel, there may be another kind of music {#blank#}3{#/blank#} (switch) on by the taxi driver. Then you go out to dinner and end up in a restaurant,{#blank#}4{#/blank#}owner thinks music will help make you eat more and spend more. Then a person {#blank#}5{#/blank#}(play) the violin comes around. This is called the “music wallpaper” and its purpose is to make you consume more. In a word, you find {#blank#}6{#/blank#} hard to find a quiet public place without music.

    Noise pollution may be {#blank#}7{#/blank#}(harm) to our hearing. It's also bad for some of our daily {#blank#}8{#/blank#} (activity).

    The fact {#blank#}9{#/blank#} you can't see, taste or smell noise may help explain why it has not received as much attention as other kinds of pollution, such as air pollution or water pollution. Many of us fail to realize we {#blank#}10{#/blank#} (surround) by too much noise. As a result, harm is done to our health without us being aware of it.

    One day, I was comfortably waiting for my flight with a good book to read when {#blank#}1{#/blank#} elderly lady was wheeled to our waiting area. I noticed the trouble she was having {#blank#}2{#/blank#} (try) to open a packet of nuts with her shaking hands. No one else was willing to meet her gaze (目光), so I {#blank#}3{#/blank#} (offer) to help. The lady was very grateful. We sat and chatted. The time came to board the plane. She could walk but needed some {#blank#}4{#/blank#} (assist), so I volunteered to help her and carry her bag.

    As I helped her get {#blank#}5{#/blank#} (settle), I noticed her “seat mate”, a businessman, looked a bit horrified at having to make the flight with her. He offered to change {#blank#}6{#/blank#} (seat) with me — and I agreed. We had a long chat. As we were entering another country we needed to fill out forms. I offered to fill {#blank#}7{#/blank#} (her) out because of her shaking hands. We landed and I needed to change planes, but I helped her first. The wheelchair she ordered was nowhere to be seen so we slowly walked to the gate {#blank#}8{#/blank#} her daughter was waiting.

    As a result, I had to run to catch my connection but, as I thought about the experience, I saw her {#blank#}9{#/blank#} my airport angel, a chance for me to hope that in the future when I'm in my eighties and traveling, someone will take the time {#blank#}10{#/blank#} (connect) with me.

    The polar bear is found in the Arctic Circle and some big land masses as far south as Newfoundland. While they are rare north of 88°, there is evidence {#blank#}1{#/blank#} they range all the way across the Arctic, and as far south as James Bay in Canada. It is difficult to figure out a global population of polar bears as much of the range has been  {#blank#}2{#/blank#} (poor) studied; however, biologists calculate that there are about 20,000-25,000 polar bears worldwide.

    Modem methods {#blank#}3{#/blank#} tracking polar bear populations have been employed only since the mid-1980s, and are expensive {#blank#}4{#/blank#} (perform) consistently over a large area. In recent years some Inuit people in Nunayut {#blank#}5{#/blank#} (report) increases in bear sightings around human settlements, leading to a {#blank#}6{#/blank#} (believe) that populations are increasing. Scientists have responded by {#blank#}7{#/blank#} (note) that hungry bears may be congregating(聚集) around human settlements, leading to the illusion(错觉) that populations are {#blank#}8{#/blank#} (high) than they actually are. Of {#blank#}9{#/blank#}  nineteen recognized polar bear subpopulations, three are declining, six {#blank#}10{#/blank#} (be) stable, one is increasing, and nine lack enough data.

    An app aimed at {#blank#}1{#/blank#} (enable) people to learn more so they can make the country stronger has become popular recently.

    The app, {#blank#}2{#/blank#} focuses on promoting the Xi Jinping Thought on Socialism with Chinese Characteristics for a New Bra and the spirit of the 19th National Congress of the Communist Party of China, is {#blank#}3{#/blank#} platform that enables Party members and the public to raise their ideological (思想的) consciousness: sense of civic duty and scientific literacy.

    The learning platform, which includes several channels, {#blank#}4{#/blank#} (provide) a huge amount of text and video material including news, periodicals, books, open courses, songs and {#blank#}5{#/blank#} (movie) for the public to browse and study {#blank#}6{#/blank#} free.

    The learning platform was {#blank#}7{#/blank#} (official) opened to the public on Jan. 1 this year, {#blank#}8{#/blank#} it has become popular among the public within a short time. According to the media, till the {#blank#}9{#/blank#} (begin) of April, the total amount of registered users of the learning platform has exceeded 100 million, and the {#blank#}10{#/blank#} (day) active users account for as high as 40 to 60 percent of the total users.

    The Wandering Earth is a Chinese science fiction movie, {#blank#}1{#/blank#} is based on the novel of {#blank#}2{#/blank#} same name by Liu Cixin, and was released on February 5, 2019, the Chinese New Year's Day.

    After learning the sun is dying out ,people all around the world feel {#blank#}3{#/blank#} (panic), so they build giant planet thrusters(星球推进器) to move the earth out of its orbit and sail {#blank#}4{#/blank#} to a new star system. The 2500 years' journey comes with unexpected dangers, but in order to save humanity, a group of young people come out bravely and fight hard for everyone's {#blank#}5{#/blank#}  (survive).

    We {#blank#}6{#/blank#}(impress) to see the theme of this film. It does not particularly show somebody's ability to save our world {#blank#}7{#/blank#} shows all the human beings are working together,  {#blank#}8{#/blank#} (spare) no effort to save this world.

    The Wandering Earth is seen by people {#blank#}9{#/blank#} the dawn(开端) of Chinese science fiction movies. It means that China's sci-fi movies have {#blank#}10{#/blank#} (official) set sail.
