There are a lot of famous women of {#blank#}1{#/blank#} (achieve) in the world. They all do {#blank#}2{#/blank#} (good) in their work, such as Lin Qiaozhi, Jane Goodall and Song Qingling. There is no doubt that they are real heroines and worth {#blank#}3{#/blank#} (praise). But in my opinion, all healthy humans have the ability to do that. It just depends on {#blank#}4{#/blank#} you have the determination to do it and whether the situation is in your favor. But never before have I {#blank#}5{#/blank#} (admire) a person so much as Helen Keller, who I just read about. She was a(n) {#blank#}6{#/blank#}  (luck) girl who could neither hear {#blank#}7{#/blank#} see. I just can't imagine how she could be so successful. {#blank#}8{#/blank#} I really don't believe is that a deaf-blind lady could become a world-famous writer. She must have met great difficulties and she must have made great efforts! If I were {#blank#}9{#/blank#} (she), I wouldn't have the courage to live on. It is {#blank#}10{#/blank#} her courage, imagination and intelligence that I was struck.

    My feelings about science have {#blank#}1{#/blank#} (complete) changed. The science teachers {#blank#}2{#/blank#} my new school are excellent and {#blank#}3{#/blank#} (friend). The science{#blank#}4{#/blank#} (facility) are very good with laboratories that have all the {#blank#}5{#/blank#} (late) equipment. Our chemistry teacher takes us to public science lectures about four times {#blank#}6{#/blank#} term, which are always interesting, because the lecturers are famous at {#blank#}7{#/blank#} (them) area of science. In the last 20 years, seven Canadian scientists {#blank#}8{#/blank#} (win) the Nobel Prize. Now {#blank#}9{#/blank#} I'm becoming more and more interested in is physics and I want to study it at university. But my parents are {#blank#}10{#/blank#} (astonish), as they always thought I would become an English teacher.

    Some students who had graduated visited their university professor. The conversation soon turned into complaints about stress in work and life. To offer his guests coffee, the professor went to the kitchen and {#blank#}1{#/blank#}(return) with a pot of coffee and {#blank#}2{#/blank#} variety of cups—porcelain, plastic, glass, some plain-looking, some expensive—telling them to help {#blank#}3{#/blank#} to the coffee.

    {#blank#}4{#/blank#} was when all the students had a cup of coffee in hand that he said, “All the nice-looking expensive cups have been taken up, {#blank#}5{#/blank#} (leave) behind the plain and cheap ones. Actually, the cup itself adds no quality to the coffee. {#blank#}6{#/blank#}all of you really want is coffee, not the cup. You consciously went for the best cups, {#blank#}7{#/blank#} then you began eyeing others' cups.”

    “Now consider this Life is the coffee; the jobs, money and position in society are the cups, {#blank#}8{#/blank#}  are just tools to hold and contain life. The type of cup we have does not change the quality of life. If we concentrate only {#blank#}9{#/blank#} the cups, we fail to enjoy the coffee. I {#blank#}10{#/blank#} (true) hope that you will never let the cups drive you ... enjoy the coffee instead.”

    In much of Asia, especially the so-called “rice bowl” cultures of China, Japan, Korea, {#blank#}1{#/blank#}Vietnam, food is usually eaten with chopsticks.

    Chopsticks are usually two long, thin pieces of wood or bamboo. They can also be made of plastic, animal bone or metal. Sometimes chopsticks are quite artistic. Truly elegant chopsticks might {#blank#}2{#/blank#}(make) of gold and silver with Chinese characters. Skilled workers also combine (组合) various hardwoods and metal {#blank#}3{#/blank#}(create) special designs.

    The Chinese have used chopsticks for 5000 years. People probably cooked {#blank#}4{#/blank#}(they) food in large pots, using twigs (树枝) to remove it. Over time, as {#blank#}5{#/blank#}population grew, people began cutting food into small pieces so it would cook more quickly. Food in small pieces could be eaten easily with twigs which {#blank#}6{#/blank#}(gradual) turned into chopsticks.

    Some people think that the great Chinese scholar Confucius, {#blank#}7{#/blank#}lived from roughly 551-479 B.C., influenced the {#blank#}8{#/blank#}(develop) of chopsticks. Confucius believed knives would remind people of killings and {#blank#}9{#/blank#}(be) too violent for use at the table.

    Chopsticks are not used everywhere in Asia. In India, for example, most people traditionally eat {#blank#}10{#/blank#}their hands.

    Two new satellites of BeiDou Navigation (导航) Satellite System (BDS){#blank#}1{#/blank#}(send) into space on a Long March-3D carrier rocket from the Xichang Satellite Launch Center in Sichuan Province, China at 2:07 a.m. on November 19, 2018. The satellites entered a Medium Earth orbit (轨道) {#blank#}2{#/blank#}(safe) more than three hours later and will work with 17 other BDS-3 satellites already in space. They are also the 42^nd and 43^rd{#blank#}3{#/blank#}(member) of the BDS satellite family.

    China launched these satellites with the aim of providing navigation services{#blank#}4{#/blank#}countries and regions which participate in the Belt and Road Proposal by the end of 2018. “This is a key and{#blank#}5{#/blank#}(value) step for BDS developing from a Chinese experimental system to a regional and then a global navigation system,” said Yang Changfeng, chief expert{#blank#}6{#/blank#}contributed much to the BeiDou system. The positioning{#blank#}7{#/blank#}(accurate) of the BDS-3 system has been improved to 2.5 meters to 5 meters, said Yang.

    {#blank#}8{#/blank#}(name) after the Chinese term for the Big Dipper, the BeiDou system has been serving China for 18 years where another six BDS-3 satellites will be put into the Medium Earth orbit from 2019 to 2020. The system is expected{#blank#}9{#/blank#}(provide) first-class services around{#blank#}10{#/blank#}globe by the end of 2020.

    Cao Yuan, a 22-year-old Chinese doctoral student in physics, was on top of {#blank#}1{#/blank#} most important scientists named by the journal Nature in 2018 for {#blank#}2{#/blank#} (discover) a "magic angle" in graphene (石墨烯).

    Cao's discovery takes a huge step in the decades-long search for superconductors (超导体) in the world. Why was Cao able to make the discovery? His teachers think it is Cao's independent learning ability and interest in doing experiments {#blank#}3{#/blank#} matter. His high school physics teacher said Cao had a strong ability to study on {#blank#}4{#/blank#} (he) own and was brave to challenge teachers and ask difficult questions. "Cao is {#blank#}5{#/blank#} (deep) curious about laboratory equipment," his college teacher told Nature. "Every time I go into Cao's office, it's {#blank#}6{#/blank#} a huge mess, with computers {#blank#}7{#/blank#} (pull) apart and pieces of telescope all over his desk."

    At 14 he {#blank#}8{#/blank#} (admit) into the University of Science and Technology of China's School of the Gifted Young, a special school to cultivate {#blank#}9{#/blank#} (teenager) into world-class talents. But Cao doesn't think himself special and often stresses that he is just an ordinary kid who {#blank#}10{#/blank#} (love) reading about science and doing experiments. "After all, we are all humans, with shortcomings and emotions," he once said.
