【题目】 Russia has announced that it is developing a specialized washing machine for astronauts to use in space. The announcement came from a missile, spaceship and space station manufacturer RKK.
Normal washing machines require gravity to function, not to mention significant amounts of water that has to be stored somewhere and increases weight — they are not suitable for space missions (任务). This means that astronauts cannot wash their clothes and either have to pack enough for their whole trip or rely on costly resupply missions and throw used items into space.
Crewmembers taking part in long-term missions on the International Space Station (ISS) often end up wearing the same garments for several continuous days and just change into new ones when they get dirty. Aside from this issue, wearing dirty clothes can be uncomfortable for the astronauts and could also provide perfect conditions for dangerous bacteria to grow and spread.
RKK has previously outlined plans for a space washing machine in a Russian space industry journal paper published in 2017. In the paper, the authors estimated (估计) that 1,450 pounds of clothes are surprisingly transported to the ISS every year to cover the requirements of just three astronauts. And this quantity could increase to three tons for a two-year voyage to Mars involving six crewmembers and could increase the costs and complexity of a mission.
The Russian scientists said that, instead of water, the washing machine would use the carbon dioxide produced by the astronauts’ breathing in the spaceship. Special technology would then turn the gas into a liquid under high pressure in order to clean the clothes.
The Russian designs are not the first proposals for a space washing machine. NASA has previously made a model of a low-power, low-water washing device (设备) which was designed to work in the microgravity of low-Earth orbit or that of the moon or Mars.
【1】Normal washing machines are not suitable in the spaceship mainly because __________.
A.they lead to serious space pollution
B.they make some bacteria spread
C.they require gravity to function
D.they increase the weight of the spaceship
【2】What might be the biggest advantage of the specialized washing machine?
A.Helping astronauts dry their clothes.
B.Having a competition against NASA.
C.Making the missions cheaper and easier.
D.Getting astronauts to adapt to the environment.
【3】Where can astronauts get the liquid for washing clothes in the spaceship?
A.From the water tank in the spaceship.B.From the outer space.
C.From the recycling water in the spaceship.D.From the gas carbon dioxide.
【4】What does the text mainly talk about?
A.Russia is developing a space washing machine.
B.A space washing machine has been used in Russia.
C.NASA’s made a model of a space washing machine.
D.RKK transports tons of clothes to astronauts in space.
【答案】
【1】C
【2】C
【3】D
【4】A
【解析】
这是一篇说明文。俄罗斯宣布正在开发一种宇航员在太空中使用的专用洗衣机。洗衣机将使用宇航员在宇宙飞船中呼吸产生的二氧化碳,而不是水。特殊的技术将气体在高压下变成液体,以便清洗衣服。
【1】细节理解题。根据第二段第一句Normal washing machines require gravity to function, not to mention significant amounts of water that has to be stored somewhere and increases weight-they are not suitable for space missions.(普通的洗衣机需要重力才能正常工作,更不用说大量的水了,这些水必须储存在某处并增加重量——它们不适合太空任务。)可知普通的洗衣机不适合在宇宙飞船里使用,主要是因为它们需要重力来运转。故选C。
【2】推理判断题。根据第四段最后一句And this quantity could increase to three tons for a two-year voyage to Mars involving six crewmembers and could increase the costs and complexity of a mission.(这一数量可能会增加到3吨,用于为期两年的火星之旅,包括6名宇航员,这可能会增加任务的成本和复杂性。)可推测定制洗衣机最大的优点是使在太空洗衣更便宜更容易。故选C。
【3】细节理解题。根据倒数第二段The Russian scientists said that, instead of water, the washing machine would use the carbon dioxide produced by the astronauts’ breathing in the spaceship.(俄罗斯科学家说,洗衣机将使用宇航员在宇宙飞船中呼吸产生的二氧化碳,而不是水。)可知宇航员会从气体二氧化碳得到洗衣服的液体。故选D。
【4】主旨大意题。根据第一段Russia has announced that it is developing a specialized washing machine for astronauts to use in space.(俄罗斯宣布正在开发一种宇航员在太空中使用的专用洗衣机。)以及文章主要内容围绕着俄罗斯正在研制一种太空洗衣机这一事件,故选A。
推理判断题要求考生在理解原文表面文字信息的基础上,做出一定的判断和推理,从而得出文章的隐含意义和深层意义。推理判断题属于主观性较强的高层次阅读理解题,做这类题目时,同学们应严格依据作者所陈述的细节、事实以及作者的措词、态度和语气等,找出能够表露作者思想倾向和感情色彩的词语,然后利用自己已获得的相关知识进行推理判断,从而得出符合逻辑的结论。如第二小题,根据第四段最后一句And this quantity could increase to three tons for a two-year voyage to Mars involving six crewmembers and could increase the costs and complexity of a mission.(这一数量可能会增加到3吨,用于为期两年的火星之旅,包括6名宇航员,这可能会增加任务的成本和复杂性。)可推测定制洗衣机最大的优点是使在太空洗衣更便宜更容易。故选C。

【题目】 Classified advertising is that advertising which is grouped in certain sections of the paper and is thus distinguished from display advertising. Such groupings as ―Help Wanted, RealEstate(不动产), Lost and Found are made, the rate charged being less than for display advertising. Classified advertisements are a convenience to the reader and a saving to the advertiser.
The reader who is interested in a particular kind of advertisement finds all advertisements of that type grouped for him. The advertisers may, therefore, use a very small advertisement if it was placed among larger advertisements in the paper. It is evident that the reader approaches the classified advertisement in a different frame of mind from that in which he approaches the other advertisements in the paper. He turns to a page of classified advertisements to search for the particular advertisement that will meet his needs.

【题目】 Since 1970, North America has lost more than 2.9 billion birds, according to a study recently published in the journal Science. In less than half a century, the bird population has declined by some 29 percent, or more than 1 in 4 birds. For the first time, researchers have discovered that rare species aren't the only birds suffering population loss. In fact, common birds-including beloved backyard friends like sparrows and blackbirds-are taking the biggest hit.
The new study used nearly 50 years of data collected largely by bird watchers and citizen scientists. "A total of 419 native migratory species experienced a net loss of 2.5 billion individuals," the study says. More than 90 percent of the total loss can be found among just 12 bird families. Some of these widespread birds can thrive almost anywhere. The large-scale loss of these hardy birds reveals they're struggling to survive throughout the world/
Birds are considered indicator species because they're crucial to ecosystems, and their populations anticipate the environment's health. Birds are "amazingly efficient" at spreading seeds. Birds also keep insect populations in check. Even the smallest bird helps control the spread of plants or insects.
The new study, however, identifies the losses without knowing all the causes. Scientists do identify habitat loss as the biggest challenge. Climate change, disrupted migration patterns and pesticide use are also major factors. Industrial agriculture may present a bigger challenge. The species disappearing most rapidly—sparrows, blackbirds and larks—are associated with agriculture. In recent decades, agriculture has grown to produce more food, but cleared landscapes have become unlivable for birds.
“We need to change the way we grow food. Birds are signaling that we are doing it wrong, "as the study says. The study offers the example of the 1990s effort to switch to no-till farming, which reduced greenhouse gases and soil erosion(侵蚀). “Farmers are innovators. And they've done it before. This is a great opportunity to have a huge impact on birds."
【1】What's the study mainly about?
A.The climate issues.B.The disappearing birds.
C.The agricultural problems.D.The environmental protection.
【2】How is the second paragraph mainly developed?
A.By listing figures.B.By giving examples
C.By analyzing reasons.D.By making comparisons.
【3】What's the main reason behind the birds' habitat loss?
A.Climate change.B.Greenhouse gases.
C.Industrial agriculture.D.Disrupted migration patterns.
【4】What does the study suggest as a solution?
A.Producing more food.B.Clearing more landscapes.
C.Reducing the use of pesticide.D.Adopting new means of farming.

My senior high school life started with military training(军训). It consisted in two parts: the theory exam and the physical training, which was lasted about two weeks. The latter was much tough than the former. Dressed in green uniforms and exposing to the sun, we had to follow the soldier daily routine and go through hard training. Each morning, we had to get up and fold quilts rapid. We should finish our meals in limited time, too. Then I think it unbearable. Besides, now looking back, I find it necessary. It is the military training which teaches me how to bear hardship and lead better life.

【题目】 When I was a child, I dreamed of becoming many things. Sometimes, I wished I was an astronaut going up into space, finding new planets and jumping around in a cool space suit. Other times, I imagined being a cowboy in the Wild West, wearing stylish cowboy boots. On other occasions, I pretended to be a famous footballer, using my skills to score lots of goals for my team.
Looking back, I realize that imagination is a wonderful thing. I was able to create entire environments and scenarios in my head, using nothing more than my brain, and to be able to adapt things in my everyday surroundings to fit the specific story of the day. Growing up with siblings (兄弟姐妹) also helped, as it meant that even bigger stories could be created, combining our ideas and putting our thoughts into action. It also allowed for more varieties in the stories, as sometimes I could be the hero while on other occasions, I would be the bad guy.
One of my all-time favorite memories as a kid was playing in my back garden. I played the role of Indiana Jones, which cleaned up at the cinema at that time, with my younger sister as my assistant and my brother as a bad person. We used everything in our garden, from the path to the fence, as part of the storyline to create obstacles that needed to be overcome, and we would keep the story going for hours!
My personal favorite game was Indiana Jones and the Stolen Easter Eggs, where my brother hid small chocolate eggs around the garden and my sister and I had to find them by answering questions or solving a puzzle. It was difficult, but eventually we found all the eggs and shared them together.
Since then, I have seen many great things and met many amazing people. The elements of fun and varieties of my creative imaginations are what I try to bring into every part of my positive life. So I can enjoy sharing with and hearing about other people’s stories, too.
【1】What do we know about the author from his childhood?
A.He enjoyed living a life full of freedom.
B.He was longing to experience adventurous things.
C.He was always imagining a bright life for his future.
D.He had a clear picture of what he would do after growing up.
【2】Which of the following can best replace the underlined word “scenarios” in Paragraph 2?
A.experiencesB.situations
C.positionsD.excuses
【3】From the passage, we know that Indiana Jones was .
A.an astronautB.a famous footballer
C.a hot filmD.a very popular book
【4】What would be the best title for the passage?
A.My Creative Imagination.B.My Childhood.
C.My Positive Life Today.D.My Pride in Myself.

【题目】 I drove a taxi to make a living. One night about twenty years ago, I went to pick up a passenger at 2:30 AM. When I arrived to collect, I found the building was dark except for a single light in a ground floor window.
I walked to the door and knocked, “Just a minute,” answered a weak, elderly voice.
After a long pause, the door opened. A small woman in her eighties stood before me. By her side was a small suitcase.
I took the suitcase to the car, and then returned to help the woman. She took my arm and we walked slowly toward the car.
She kept thanking me for my kindness. “It’s nothing,” I told her. “I just try to treat my passengers the way I would want my mother treated.”
“Oh, you’re such a good man.” She said. When we got into the taxi, she gave me an address, and then asked, “Could you drive through downtown?”
“It’s not the shortest way,” I answered quickly.
“Oh, I’m in no hurry,” she said. “I’m on my way to a hospice(临终医院). I don’t have any family left. The doctor says I don’t have very long.”
I quietly reached over and shut off the meter(计价器).
For the next two hours, we drove through the city. She showed me the building where she had once worked, the neighborhood where she had lived, and the furniture shop that had once been a ballroom where she had gone dancing as a girl.
Sometimes she’d ask me to slow down in front of a particular building and would sit staring into the darkness, saying nothing.
At dawn, she suddenly said, “I’m tired. Let’s go now.”
We drove in silence to the address she had given me.
“How much do I owe you?” she asked.
“Nothing.” I said.
“You have to make a living,” she answered. “Oh, there are other passengers,” I answered.
Almost without thinking, I bent and gave her a hug. She held onto me tightly. Our hug ended with her remark, “You gave an old woman a little moment of joy.”
【1】The old woman chose to ride through the city in order to ______.
A.show she was familiar with the city
B.let the driver earn more money
C.see some places for the last time
D.reach the destination on time
【2】The taxi driver did not charge the old woman because he ______.
A.shut off the meter by mistake
B.wanted to do her a favor
C.had received her payment in advance
D.was in a hurry to take other passengers
【3】What can be inferred from the story?
A.Giving is always a pleasure.
B.People should respect the old.
C.People should learn to appreciate others’ concern.
D.An act of kindness can bring people great joy.
