21、British sculptor Jason Taylor has made it his mission to use his talent to conserve our ecosystems by creating underwater museums. Over the years, the environmentalist has put over 850 massive artworks underwater worldwide. On February 1, 2021, Taylor launched his latest work---The Underwater Museum of Cannes.
“The main goal was to bring attention to the fact that our oceans need our help,” Taylor told Dezeen. “Ocean ecologies have been destroyed by human activity in the Mediterranean over the past few decades, and it is not obvious what is taking place when observing the sea from afar.”
The Underwater Museum of Cannes contains 6 sculptures featuring local residents of various ages. They range from Maurice, an 80-year-old fisherman, to Anouk, a 9-year-old student. Towering over 6-feet-tall and weighing 10 tons, the faces are sectioned into two parts, with the outer part like a mask. The mask indicates that the world’s oceans appear powerful and unbeatable from the surface but house an ecosystem that is extremely fragile to careless human activities.
Though the waters surrounding the sculptures now appear a pristine blue, the seabed was filled with old boat engines, pipes, and other human-made trash when the project began about four years ago. Besides removing the trash, Taylor also restored the area’s seagrass. Just one square meter of the seagrass can generate up to 10 liters of oxygen daily. The seagrass also helps prevent coastal erosion and provides habitats for many ocean creatures.
“The idea of creating an underwater museum was to draw more people underwater and develop a sense of care and protection,” Taylor told Dezeen. “If we threw unwanted waste near a forest, there would be a public outcry. But this is happening every day in our surrounding waters and it largely goes unnoticed.”
【1】What are the underwater museums intended to do?
A．To make huge profits.
B．To raise awareness of protecting the ocean.
C．To show Jason Taylor’s talent.
D．To draw attention to endangered sea animals.
【2】Why does the outer part of the sculptures look like a mask?
A．To popularize the features of the locals.
B．To remind people to protect themselves.
C．To reflect people’s protection of the ocean.
D．To stress the sensitiveness of the ecosystem.
【3】What’s Paragraph 4 mainly about?
A．How the project was started.
B．How the seagrass was restored.
C．What recovery effort the project made.
D．Why the surroundings were improved.
【4】What can we infer from what Jason Taylor said in the last paragraph?
A．The situation of the ocean is easily ignored.
B．The destruction caused to the ocean is noticeable.
C．Forests play a more important role in ecosystems.
D．People have zero tolerance to damage done to nature.
22、 Scientists have created the world’s first living, self-healing (自愈) robots using stem cells from frogs. Named after the African clawed frog from which they take their stem cells, xenobots are less than a millimeter wide (0. 04 inches) — small enough to travel inside human bodies. They can walk and swim, survive for weeks without food, and work together in groups. These are “entirely new life-forms,” said project co-leader Michael Levin, director of the Allen Discovery Center.
The researchers removed living stem cells, which have the ability to develop into different cell types, from frog embryos (胚胎), and left them to incubate (孵化). Then, the cells were cut and reshaped into specific “body forms” designed by a supercomputer.” They’re neither a traditional robot nor a known species of animal,” said robotics expert Joshua Bongard. The cells then began to work on their own and even have the regenerative power; when the scientists cut the living robot almost in half, its cells automatically zippered its body back up.
Xenobots don’t look like traditional robots-they have no shiny clothing or robotic arms. Instead ,they look more like a tiny drop of moving pink flesh. The researchers say this is deliberate-this biological machine can achieve things typical robots of steel and plastic cannot do.” Traditional robots degrade (降解) over time and can produce harmful ecological and health side effects,” researchers said in the study. As biological machines, xenobots are more environmentally friendly and safer for human health, the study said.
Research is being done into using the robots to clean up radioactive waste or even microplastics from the oceans. Scientists are also trying to include a greater variety of cells; a new nervous system for example. However, some people argue that the addition of nerve cells would cause moral problems. The general public have also expressed concern that humans would be taken control of by robots. However, Michael Levin thinks there’s no need to worry. “Xenobots have no ability to reproduce or evolve. The supercomputer which is used to produce them does use artificial intelligence. But for now, all is fine,” said Levin.
【1】What is the text mainly about?
A.The advantage of AI technology. B.The introduction of a latest robot.
C.The medical value of African frogs. D.The application of robots in medicine.
【2】Which of the following best explains “regenerative” underlined in Paragraph 2?
A.Healing by itself. B.Replacing old cells.
C.Living much longer. D.Defending against attacks.
【3】What do we know about xenobots?
A.They can break up steel and plastic while degrading.
B.They can do everything that traditional robots can do.
C.They do less harm to the environment and human health.
D.They often change their color deliberately while moving.
【4】What is Michael Levin’s attitude toward the development of xenobots?
A.Ambiguous. B.Positive.
C.Skeptical. D.Cautious.
23、Chinese female scientist Tu Youyou won the 2015 Nobel Prize in medicine on October 5 for her discoveries concerning a novel treatment against Malaria（疟疾）. This is the first Nobel Prize given to a Chinese scientist for work carried out within China.
Tu shared the prize with Irish-born William Campbell and Satoshi Omura of Japan, who were honored for their revolutionary anti-roundworm treatment. 84-year-old Tu is awarded this prize for her contribution to cutting the death rate of malaria, reducing patients’ suffering and promoting mankind’s health. Although she received several medical awards in the past, the 2015 Nobel Prize is definitely the most privilege reward that recognizes Tu’s dedication and perseverance in discovering artemisinin（青蒿素）, the key drug that battles malaria-friendly parasites（寄生虫）.
However, her route to the honor has been anything but traditional. She won the Nobel Prize for medicine, but she doesn’t have a medical degree or a PhD. In China, she is even being called the “three-noes” winner: no medical degree, no doctorate, and she’s never worked overseas. No wonder her success has stirred China’s national pride and helped promote confidence of native Chinese scientists.
The fact that Tu has none of these three backgrounds reminds us that science should be more accessible to all. One shall be able to become a scientist no matter what kind of background he or she comes from, as long as one dives into scientific research. There have been discussions on people who really love science but are never able to achieve much during their whole life. Their contributions can never be ignored. They work so hard to prove the wrong way so that the future researchers will be closer to the right one.
As the first Chinese mainland Nobel Prize Winner of natural science award, Tu’s record-breaking winning also serves as a reminder to those who are too eager for instant success. Science is never about instant success. Tu spent decades on scientific research before its value is officially acknowledged. There is no way to measure how much one devotes to science and compare it with how much reward he or she may get.
【1】It can be concluded from the text that __________.
A. Tu worked home and abroad to conduct her research
B. Tu got the Nobel Prize for her anti-roundworm treatment
C. The Nobel Prize is the first award to recognize her work
D. Her discovery of artemisinin has helped to cut Malaria death rate
【2】The author seems to agree that a person who is more likely to become a scientist is the one with__________.
A. a sense of national pride
B. relevant academic knowledge
C. enthusiasm for scientific research
D. a desire to achieve success
【3】In writing the passage, the author intends to ___________.
A. remind readers of the principles of scientific research
B. discourage the pursuit of instant success in science
C. inform readers of the news and make comments
D. praise the award winner and encourage scientific research
24、Your car is a necessary part of your life. You use it every day. Of course, you want to hold on to it so you make sure it has the latest alarm and immobilizer. But despite all these, cars like yours are still stolen every day. In fact, in this country, one car is stolen almost every minute! And if your car is stolen, you only have a 50:50 chance of seeing it again.
Each year, car crime costs nearly £3 billion. Of course, if you’re insured, you won’t lose out, or will you? Firstly, you will have to pay extra insurance later on, and then you may not be offered the full amount by the agent. You will probably have to hire a car and you will also lose the value of the contents and accessories (配件) in the car.
Now comes the solution. An RAC Trackstar system, hidden in one of 47 possible secret locations in your car, is the key of our system. If your car is stolen, radio signals are sent at twenty-second intervals from the car to the RAC Trackstar National Control Center via a satellite network. Then a computer gives the vehicle’s exact location, speed and direction.
The RAC Trackstar National Control Center, which operates 24 hours a day, 365 days a year, will immediately inform the police in the area where the car is located. Because the police receive information every twenty seconds, they will always know the vehicle’s location. Once the thief has been arrested, your car will be returned to you.
RAC Trackstar is unique in being able to provide the National Control Center with details of the exact location of your car, its speed and direction. And speed is the key to successful recovery of a stolen vehicle. RAC Trackstar Control will immediately tell the police if you report your car stolen and under the 24-hour Guardian Option. It will also tell you if your car has been stolen. RAC Trackstar’s constant updates mean the police are kept informed of the car’s location. All these greatly improve your chances of seeing your car again.
【1】If your car is stolen, you will have to ______.
A. pay more insurance
B. hire a new car
C. buy a RAC Trackstar system
D. inform the National Control Center
【2】The Trackstar system can tell the police ______.
A. how the car is stolen
B. who the thief is
C. where the car is
D. what brand the car is
【3】The underlined word “It” in the last paragraph refers to ______.
A. the local police station
B. the RAC Trackstar Control
C. the Guardian Option
D. the insurance company
【4】According to the passage, people with RAC Trackstar ______.
A. automatically find directions
B. seldom get their vehicles damaged
C. are more likely to get the stolen cars back
D. have less chance of being in an accident

26、阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。
It was freezing! Temperature was zero degree!
During patrolling（巡逻）, a group of soldiers were passing through a mountainous path. Their commander was also with them. The way became difficult and dark. The soldier started to feel tired and difficult to continue walking down the path.
Just a little ahead, they saw a tea shop, but when they reached there, they saw it was closed. Every soldier looked at the commander with teary eyes.
The commander understood everyone wanted to have a rest. So he ordered that they should rest there for some time.
Everyone sat there. Just then one of them said, “If we could get a cup of tea in this cold day, we could feel a little relieved.” The commander understood that his soldiers wanted to drink tea so he said. “But the shop is locked, how can we drink tea?”
And then a soldier said, “Sir, let’s break the lock. After all, we protect these people. One cup of tea... at least this is our right. It isn’t like we steal things from the shop. We just want to drink a cup of tea.”
Saying this, the soldier broke the lock of that tea shop.
Everyone drank tea, ate biscuits and continued their patrolling, but before leaving, the commander left two notes of RS（卢比） 500 on the table of that tea shop.
In the next morning, when the shop owner saw that the lock of his tea shop was broken, he cried and said, “Oh, God! My child is sick. I don’t even have money for his treatment and now my shop got robbed!” Then he went inside nervously and saw that all stuff（物品） was there except for some biscuit packets. Worried as he sat on the table, he saw two notes of RS 500 on it. Seeing the money, he immediately jumped with joy, but still not knowing what has happened and where the money was from.
注意：
1.续写词数应为150左右；
2.请按如下格式在答题卡的相应位置作答。
The next day, when the troops returned along the same road, they stopped at the same tea shop drink tea.
