Some people live in the world for body while {#blank#}1{#/blank#} for dignity(尊严).

    I once took a walk along the street on a Saturday dusk, with a Pepsi can in my hand. An old woman in ragged clothes, {#blank#}2{#/blank#}was living on collecting {#blank#}3{#/blank#} (use) cans, jars and tins, moved slowly towards me, with a bag on the back! {#blank#}4{#/blank#} (walk) nearer, she looked up at me and then fixed her eyes on my can. At that time, I hadn't finished my cola, so I gave {#blank#}5{#/blank#} several coins instead.

    She stared at me for a few seconds {#blank#}6{#/blank#} handed back the money. Quite confused, I asked: “Why not? Isn't that {#blank#}7{#/blank#} you want?” “I am not a beggar,” she said {#blank#}8{#/blank#} (serious), word by word.

    Instantly, I felt so sorry. I had intended to help her, completely misunderstanding her. Thus I hurt her. What I could do at that moment was only to drink up the cola and handed her {#blank#}9{#/blank#} emptied can. This time, she gave me a smile {#blank#}10{#/blank#} satisfaction and gratitude in her eyes. The woman is poor in material life but is so respectable as a man. I am not only moved but also have learned a good lesson.

    In recent years many TV shows have become extremely popular among Chinese audience. Those programs, ranging {#blank#}1{#/blank#} talent or dating shows to reality shows,{#blank#}2{#/blank#} (receive) both commercial success and public attention.

Their popularity is {#blank#}3{#/blank#} (main) based on simple facts. First, they care about social concerns. Second,  without exception, they explore a perfect balance between the international forms and Chinese expressions.

    Despite apparent highlights,  much room {#blank#}4{#/blank#} (leave) for improvement. Above all, commercial interests often outweigh  {#blank#}5{#/blank#} (education) purposes , causing many {#blank#}6{#/blank#} (complain) about the unbearable advertisements. In addition, some sharp remarks,{#blank#}7{#/blank#} they are eye-catching, may have misleading effects {#blank#}8{#/blank#} the youth.

    In my opinion, such shows should shoulder more responsibility instead of merely {#blank#}9{#/blank#} (entertain) the public.{#blank#}10{#/blank#} is expected, these programs should be positive in their forms as well as functions. Meanwhile, the media should also safeguard the values of our society.

    Disposing(处理) of waste has been a problem since humans started producing it. As more and more people choose to live close together in cities, the waste disposal problem becomes {#blank#}1{#/blank#}(increase) difficult.

    During the eighteenth century, it was usual for several neighboring towns to get together to select a faraway spot{#blank#}2{#/blank#}a dump site(垃圾场). People {#blank#}3{#/blank#} (transport) household rubbish, rotted wood, and old possessions to the site. Regularly some of the trash was burned and the rest was buried. The {#blank#}4{#/blank#} (pleasant) sights and smells caused no problem because nobody lived close by. Factories mills (制造厂), and other industrial sites also had waste to be disposed of. Those located on rivers often just dumped the unwanted {#blank#}5{#/blank#} (remaining) into the water. Others built huge burners with chimneys to deal with the problem.

    Several facts make these choices {#blank#}6{#/blank#} (accept) to modern society. The first problem is space. Dumps,{#blank#}7{#/blank#}are now called landfills, are most needed in heavily populated areas. Such areas rarely have empty land suitable for this purpose. The land is either too expensive or too close to residential neighborhoods. A long distance dump has been a common practice,{#blank#}8{#/blank#} once farm areas are refusing to accept rubbish from elsewhere, cheap land within trucking distance of major city areas is nonexistent.{#blank#}9{#/blank#} (aware) of pollution dangers has resulted in more strict rules of waste disposal. Pollution of rivers, ground water, land and air is a price people can no longer pay to get rid of waste. The amount of waste, however, continues to grow.

    {#blank#}10{#/blank#} (recycle) efforts have become commonplace, and many towns require their people to take part. Even the most efficient recycling programs, however, can hope to deal with only about 50 percent of a city's reusable waste.

    Once a group of 50 people was attending a seminar. Halfway through his talk, the speaker stopped and decided {#blank#}1{#/blank#} (create) a group activity. He went around the hall and gave each person a balloon. Each one was asked to write his or her name on the balloon {#blank#}2{#/blank#} (use) a marker pen. Then all the balloons were {#blank#}3{#/blank#} (collect) and put in another room.

    The speaker then led the group to the room full of balloons and asked them to find the balloon {#blank#}4{#/blank#} had their name written on, within five minutes. Everyone was {#blank#}5{#/blank#} (hurried) searching for their name, bumping into each other, pushing each other around. It was chaos. At the end of the five minutes no one could find {#blank#}6{#/blank#} (them) own balloon.

    Now each person was asked to randomly collect {#blank#}7{#/blank#} balloon and give it to the person whose name was written on it. Within two minutes everyone {#blank#}8{#/blank#} (have) their own balloon. When everyone quieted down, the speaker began to talk, saying that this is exactly what was happening in our {#blank#}9{#/blank#} (life)．Everyone is hurriedly looking for happiness, and not knowing where it is.

    Our happiness sometimes lies in the happiness of other people. Give them happiness {#blank#}10{#/blank#} you will get your own happiness.

    China's Chang'e 5 mission {#blank#}1{#/blank#} (successful) delivered samples of moon rocks and dust to Earth on December 17, 2020. It marks {#blank#}2{#/blank#} first time in 44 years that moon rocks have been brought back to our planet.

    The sample capsule landed in Inner Mongolia {#blank#}3{#/blank#} a little after 2:00 a.m. Thursday local time. The drop-off was the ending of a 23-day mission that began on November 23, {#blank#}4{#/blank#} China sent up Chang'e 5 from a site on Hainan Island. The mission's goal was {#blank#}5{#/blank#} (collect) at least four pounds of material and bring it back to Earth.

    The material collected by Chang'e 5 was from a site in the northwest region of the moon's near side. This area was formed more recently, and the rocks here {#blank#}6{#/blank#} (think) to be only about 1.2 billion years old now. That means scientists {#blank#}7{#/blank#}(study) the material could learn more about the {#blank#}8{#/blank#} (evolve) of the moon.

Although Chang'e 5 was a short mission, it was one of {#blank#}9{#/blank#} (complex) projects undertaken by the Chinese space program so far. The country is far from done with the moon—Chang'e 6, {#blank#}10{#/blank#} (it) second lunar sample return, is ready to launch in 2023 or 2024.
