21、A team of University of Houston researchers is reporting a newly recognized process of drug metabolism(代谢) in the intestines(肠)—followed by recycling through the liver(肝脏)—that could have important meanings for developing treatments for intestinal diseases and for taking multiple drugs at the same time.
“The intestines play an important role in metabolizing and recycling certain plant compounds and drugs,” reports Ming Hu, a professor in University of Houston.
The new information could help chemists develop better drugs and doctors fine-tune medication dosing, especially when a patient takes multiple drugs at the same time.
Scientists have long recognized that bile(胆汁) acid is produced in the liver and released into the intestines and is then recycled back through the liver for reuse as the bile, Some drugs that are metabolized in the liver also go through this process.
“The liver has long been considered the most important organ for drug metabolism,” said Hu. “But we’ve shown that the intestines also play a major role in drug metabolism.”
In the experiments, the team administered 16 different types of drugs directly to the liver or intestines and then tracked what happened to the treatments. They found that some drugs and plant compounds were metabolized in the intestines and the metabolites were then transported to the liver before being cycled back into the intestines.
“In this process, the liver acts only as a recycling organ, which is rare, since the liver is known to be the metabolic ‘superstar’ organ in humans,” said Hu. “This may explain why some drugs or plant compounds have larger effects on the intestines than anticipated the body. We hope our findings will be useful for medicinal chemists to design new drugs tailored to treat intestinal diseases.”
【1】What is the new discovery of University of Houston researchers?
A．A new cure for intestinal diseases.
B．The way the liver recycles medicines.
C．A newly recognized effect of taking multiple drugs.
D．The phenomenon of drug metabolism in the intestines.
【2】What does the underlined word “administered” in Paragraph 6 mean?
A．Produced.
B．Studied.
C．Gave.
D．Introduced.
【3】What’s the role of the liver in the newly discovered process?
A．A recycling organ.
B．A metabolic organ.
C．A transporting organ.
D．A drug tracking organ.
【4】Which of the following is a suitable title for the text?
A．Where Are Drugs Metabolized?
B．How Are New Drugs Designed?
C．What’s the Metabolic Superstar?
D．Why Are Intestinal Diseases Hard to Cure?
22、Never play games with a bot(robot)—it will find a way to cheat if it can. A team from OpenAI, an artificial intelligence lab in San Francisco, has developed artificially intelligent bots that taught themselves to cooperate by playing hide-and-seek. The bots also learned how to use basic tools to help them win.
Bowen Baker at Open AI and his colleagues wanted to see if the team-based dynamics of the OpenAI Five could be used to produce skills that could one day be useful to humans.
The researchers set their bots loose in a simulated (模拟的) environment filled with fixed walls, movable boxes and ladders, and left them to play team games of hide-and-seek. The bots each had their own view of the world and couldn’t communicate with each other directly.
At first, the hiders simply ran away. But they soon worked out that the quickest way to stop the seekers was to find objects in the environment to hide themselves from view. The seekers learned that they could move boxes around and use them to climb over walls. The bots then discovered that being a team-player -passing objects to each other or cooperating on a hideout -was the quickest way to win.
But the real surprise came when the bots started making use of problems or faults. Seekers found that if they pushed a ladder towards a wall, they could launch themselves into the air and spot hiders from above. Hiders found that they could get rid of the ladders by pushing them aside.
It shows that AIs are able to find solutions that humans miss, says Baker. “Maybe they’ll even be able to solve problems that humans don’t yet know how to.” However, it is a large leap (跳跃) from virtual hide and seek to real problem-solving. “The main limitation is that it is in simulation,” says Chelsea Finn at Stanford University.
【1】Why did Bowen and his colleagues conduct the research?
A．To teach bots to play games.
B．To train bots to use basic tools.
C．To find if bots may cheat like humans.
D．To see the potential of robots cooperation.
【2】What’s the third paragraph mainly about?
A．The tools of the research.
B．The design of the research.
C．The competitors of the game.
D．The environment of the game.
【3】What does the underlined word “It” in the last paragraph refer to?
A．Passing objects.
B．Moving boxes around.
C．Making use of faults.
D．Hiding themselves from view.
【4】What does Chelsea think of the finding of the research?
A．It can bridge a gap in the AI research.
B．It will not be influenced by the real world.
C．It will definitely help the real problem-solving.
D．It may not be realized out of the virtual world.

24、 A months-long drought affecting most of southern Africa has led to serious food shortage for millions of people.
The United Nations estimates(估计 )that more than 11 million people are facing extreme lack of food. The World Food Program says southern Africa has received normal rainfall in just one of the past five growing seasons.
Among the hardest hit areas is South Africa’s Northern Cape province. There, many farmers are struggling to keep their families and animals alive as they lose money and debt grows. Sheep farmer Louis told the AP he had lost more than 400 sheep over the past two years. He said this drought was the worst during his 45 years of farming. He got emotional while explaining that he now accepted donations of animal feed so he could keep the rest of his animals alive.
It’s estimated that this area will need at least $28 million over the next three months to assist 15, 500 affected farms. So far, South Africa’s government has promised $2 million.
Gertruida from Vosburg told the AP things had gotten so bad that she shared her family’s food with their animals. Small children were hungry, too. At Vosburg’s only school, Delta Primary School, large groups of children lined up for what became both breakfast and lunch. The meal usually included corn meal, vegetables and soup. “It’s very hard for the parents to actually feed their children at home, “one teacher said.
In Kimberley, the capital of Northern Cape, government officials give out money from the $2 million disaster aid program. The job can be difficult because some farmers live in places that are not easy to get to.
【1】Which of the following is TRUE about the drought?
A.It has lasted a whole month.
B.It is the worst in Africa’ s history.
C.It has killed 400 sheep altogether.
D.It affects Northern Cape worst.
【2】Why were Louis’ feelings out of control?
A.Because his debts grew.
B.Because he got donations.
C.Because he lost more sheep.
D.Because his children went hungry.
【3】What’s the text mainly about?
A.Government takes measures to fight the rare drought.
B.People carry out self-rescue after the severe drought.
C.Farmers suffer a loss of animals because of the drought.
D.Deadly drought in Southern Africa leaves millions hungry.
25、I was a boy of nine in 1960. I used to mow the lawn for Mrs. Long. She paid me little for the job, but promised to give me a Christmas present.
I spent much time _________ what it would be. Many boys had baseball gloves or ice skates and I was eager to have any of these. “It would _________ be a baseball glove,” I _________ with myself. “She wouldn’t know much about baseball.” So I was convinced that she would give me ice skates. I even imagined myself upon the skates.
As Christmas approached, it was with _________ that I stopped myself from reporting to Mrs. Long and demanding my present. On December 22, I presented myself at the door of the house. Mrs. Long handed me a small box which under no circumstances could _________ a pair of skates. I was disappointed. When lifting it from her, I was curious about the _________ of the present. It weighed almost nothing.
“What is it?” I asked.
“A kind of magic,” she said. Her words were enough to set my mind _________ with new possibilities.
On Christmas morning, I had this box on my knees. With great _________ I opened the box to find inside ten sheets of black paper, each labeled in colorful letters, Carbon Paper Regal Premium. “What is it?” I asked. Mum took two pieces of white paper, placed between them one of the black paper, and wrote my name on the upper sheet. Then she handed me the second sheet, which her pencil had in no way touched. There was my name!
It was a miracle to my _________ mind. In that one moment, I remembered the ideas about the duplication(复制) of words and the printing and the mystery of spreading ideas. Thank Mrs. Long for her wisdom to guess that a boy might profit from a present totally outside the realm of his ordinary experience.
The __________ present merely satisfies a temporary desire; the great one lights up all the years of life that remain.
