21、Alexander Miles is an African-American inventor who is largely known for his contribution to the elevator industry. He was awarded a US patent in 1887 for his design for the elevator. The design allowed the doors of the elevator to open and close automatically when it stopped on a floor. 【1】
Alexander Miles’ invention was an improvement on the previous models of the elevator, mainly due to safety concerns. Older models of the elevator would not close automatically before the elevator started to move. 【2】 There were accidents where people would fall out of the elevator and into the shaft (电梯通道).
【3】 His device worked by attaching a flexible belt to the elevator cage. When the belt bumped against drums that were placed directly above and under the floors, it caused the elevator doors to open and close. The doors were further operated through a series of levers and pulleys (滑轮).
Sometimes, people might mistake Alexander Miles for inventing the elevator door system. 【4】 The first patent for elevator doors was given to John W. Meaker. Mr. Meaker was awarded the patent for the creation of the elevator door system in 1874, 13 years before Mr. Miles’ patent.
Despite the confusion, Alexander Miles made a huge contribution to the elevator. 【5】 His patent for automated opening and closing doors is still used by most elevators today.
A．Actually, it’s not the case.
B．They are located below and above the doors.
C．Before his design, the doors had to be opened by hand.
D．This could be dangerous if someone forgot to close the door.
E．Modern-day elevator doors are still designed based on his basic principles.
F．At this time, Miles was inspired to work on elevator door mechanisms.
G．Miles’ improvement to the elevator was basically a matter of structure.
22、Charlie Bucket，the beloved hero of British writer Roald Dahl’s evergreen 1964 children’s story Charlie and the Chocolate Factory ,is like all of Dahl’s readers．We may come from richer or poorer families than Charlie does，but we all share his desire to win that golden ticket to explore the wonders of Mr Willy Wonka’s candy factory． ． ．
Mr Wonka is the most famous chocolate maker in the world．His chocolates
are not just sweet and delicious but little works of art. He makes hot ice creams for cold days and candies that change color every 10 seconds as you suck on them.
So, naturally, when Mr Wonka announces a competition to visit his famous chocolate factory, very kid in the world is wildly excited. To win a place you have get a ticket. To get a ticket you have to be lucky, finding a golden ticket beneath the silver foil(箔) when you buy a bar of Wonka's chocolate.
Charlie wants a ticket more than anyone. But his family is so poor that they have no money to spare for candy. Charlie watches on the news as each lucky kid gets a ticket. When his grandpa slips Charlie some money and tells him to buy a Wonka bar, it seems that the story will change. But no, there's no ticket in the bar.
But Charlie's luck does change. Against all the odds(逆境),when he has given up all hope,he finds himself holding the last golden ticket.
So Charlie，along with other kids，starts his magical trip. Inside, there are more amazing things than you could ever imagine.
People love to read about the downtrodden(受压迫的)hero who comes out on top. but Charlie and the Chocolate Factory is much more than a simple story.“Dahl's words.,wild imagination and menacing(令人讨厌的)adult characters all combine to make his work ring so true ,”commented Publishers Weekly. “The way he celebrates the innocence of childhood never goes out of style.”

23、Over the past 50 years, scientists have been attempting to understand one of the most pressing iss ues in biology — understanding how proteins fold. Recently, DeepMind, a leader in Al, demonstrated their project AlphaFold which won first place in a contest that encourages teams to accurately predict protein structures.
Proteins are one of the main building blocks of life — they help us maintain our health and fuel our bodies with energy. Each protein is made up of one-dimensional-strings of amino acids (氨基酸), and the folding process occurs when the chains fold into a three-dimensional shape to create an active protein. Protein folding is important as the structure of the protein determines its function. However, issues may arise during the folding process as proteins can become unfolded or misfolded, resulting in diseases and life-threatening conditions, such as Parkinsons disease, Alzheimer’s disease, and more.
Being able to predict a proteins shape is incredibly important. It will allow scientists to develop the right medicines and drug molecules (分子) that can join to the protein and possibly fix, or alleviate the consequences. Fixing damaged proteins is the key to solving a wide variety of diseases
DeepMind takes inspiration from the human brain and its pattern-matching abilities, known as neural networks. To train the algorithm (算法), scientists feed it several amino acid chains and the final protein structure. The machine gradually learns by observing the patterns, until it is ready to start making predictions.
Andrei Lupas, an evolutionary biologist in Germany, had been trying to understand a protein structure for a decade. Alpha Fold solved the problem in just thirty minutes!
There are some who question AlphaFold’s abilities, claiming that the algorithm may not work as well in real-life settings where amino acid strings are more complex. But despite this DeepMind’s achievement is definitely a milestone in biology. Not only is DeepMind in the process of applying this to the current COVID-19 pandemic and what proteins are affected but future pandemics and viruses could also be fought with ease!
【1】What can we infer from the second paragraph？
A．Unfolded proteins are incredibly active.
B．Some diseases result from damaged proteins.
C．All proteins have the similar shapes.
D．The function of proteins decides their structures.
【2】What does the underlined word “alleviate” in paragraph 3 mean？
A．Suffer
B．Cause
C．Bear
D．Ease
【3】Why does the author mention Andrei Lupas？
A．To stress the drawback of AlphaFold.
B．To analyze the barriers for AlphaFold
C．To explain the learning process of AlphaFold.
D．To prove the efficiency of AlphaFold.
【4】What might be the best title for the text？
A．AI solves the biggest problem in biology
B．AI helps fix damaged proteins
C．AI makes proteins change their shapes
D．AI finds the cause of the illnesses
24、The fish eggs, all 200 of them, were settled and ready to go. The ground crew had counted the eggs carefully, and sealed them tightly within a plate filled precisely to the edge with seawater.
The countdown, and then—ignition (点火)! For two full minutes, the precious eggs suffered a violent shaking as the rocket’s engines exploded to life, and then rise to the heavens. These eggs were on their way to low Earth orbit. Next stop: the moon.
Well, they haven’t actually left yet. But after a recent simulation (模拟) designed to re-create the intense shaking of a typical takeoff, researchers in France found that the eggs survived. It’s a crucial discovery in the progress of the Lunar Hatch, a program that aims to determine whether astronauts could successfully raise fish on a future moon base.
Finally, Cyrille Przybyla, an aquaculture (水产养殖) researcher at the French Research Institute for Exploitation of the Sea who led the research, dreams of designing a lunar fish farm that uses water already on the moon to help feed residents of the future Moon Village set to be established by the European Space Agency (ESA).
Przybyla’s hope is to offer lunar residents fresh, inviting, protein-rich fish—not just packets of freeze-dried food. “I proposed the idea to send eggs, not fish, because eggs are very strong,” he says.
Besides, Przybyla suggests there will be other benefits for astronauts who may one day find themselves raising animals in space. “From the psychological point of view, it’s better to have a reminder of Earth–you have a garden; you have a tank with fish,” he says.
Designing self-contained and self-supporting systems for food production beyond Earth will be crucial for future space exploration programs, says Luke Roberson, a researcher at NASA’s Kennedy Space Center in Florida. And he says Przybyla’s study is “a great first step” toward showing that aquaculture is a practical part of that future.

【3】What’s the psychological advantage of raising animals in space?
A．It can get rid of loneliness.
B．It diversifies the space food.
C．It gives astronauts something to do.
D．It helps astronauts remember the Earth.
