21、Humans’ invention of zero was vital for modern mathematics and science, but we’re not the only species to consider “nothing” a number. Parrots and monkeys understand the concept of zero, and now bees have joined the club, too.
Honey bees are known to have some numerical skills such as the ability to count to four, which may come in handy when keeping track of landmarks in their environment. To see whether these abilities extended to understanding zero, researchers trained 10 bees to identify the smaller of two numbers. Across a series of trials, they showed the insects two different pictures displaying a few black shapes on a white background. If the bees flew to the picture with the smaller number of shapes, they were given delicious sugar water, but if they flew toward the larger number, they were punished with bitter-tasting food.
Once the bees had learned to consistently make the correct choice, the researchers gave them a new choice: a white background containing no shapes at all. Even though the bees had never seen an empty picture before, 64% of the time they chose it rather than a picture containing two or three shapes, the authors report today in Science. This suggests that the insects understood that “zero” is less than two or three. And they weren’t just going for the empty picture because it was new and interesting. Another group of bees trained to always choose the larger number tended to pick the nonzero image in this test.
In further experiments, the researchers showed that bees’ understanding of zero was even more complex: for example, they were able to distinguish between one and zero-a challenge even for some other members of the zero club. Advanced numerical abilities like this could give animals an evolutionary advantage, helping them keep track of predators（捕食者）and food sources. And if an insect can display such a thorough grasp of the number zero, write the researchers, then this ability may be more common in the animal kingdom than we think.
【1】According to the trials, the researchers have found that bees ________.
A. have the same intelligence as parrots and monkeys
B. can count many numbers after being trained
C. can identify the smaller number quickly
D. understand the concept of zero
【2】The researchers trained another group of bees to ________ .

22、For many health-conscious people, bread is a little slice of hell. Shelves of multigrain loaves—or friends passing around sourdough (酵母面包) starters and attaching the word artisanal (手工艺性的) to the ancient combination of yeast (酵母), flour and water—have led consumers to believe whole grain bread is healthier than industrial white bread. That trend has made for a lot of expensive sandwiches.
Fortunately, a new study by researchers at the Weizmann Institute of Science is here to cut through the confusion. In the study, published in Cell Metabolism, researchers randomized 20 participants to consume either processed white bread or artisanal whole wheat sourdough in order to compare the effects of each on the body.
Before the study started, all participants consumed the same amount of white and nonwhite bread for several days. Then each group ate, on average, at least 100 grams of bread—three to four slices—per day for one week. After a two-week break, the groups switched types for another bread-laden week. The total amount of calories the participants consumed remained constant the duration of the study.
The researchers were surprised by what they found. “There were no clinically significant differences between the effects of these two types of bread on whatever we measured,” said computational biologist Eran Segal, senior author of the study in a statement. Those measured included glucose levels upon waking, fat and cholesterol levels, the amounts of essential minerals in the bloodstream and several indicators of tissue damage. Segal and colleagues examined 20 variables and found not one notable difference between the white bread eaters and the artisanal bread eaters. The key finding: It wasn’t that both breads had no effect on the body. Rather, they both did equal damage. As it turns out, half the participants had a higher glycemic response to industrial white bread, and half had the higher response to artisanal sourdough bread.
The researchers also found that which bread was best for you can be predicted based on the bacteria present in your body. They found that the “profile”—the variety of bacterial species—correlated with the glycemic (血糖) response to each bread. The small size of the study means the results should be considered preliminary. The researchers hope to study these predictors more carefully as a potential way to improve nutritional recommendations, says biologist Avraham Levy, another study co-author.
In short, the study provides vital evidence that we need to stop judging each other in the supermarket bread aisle.
【1】Why does the author use “fortunately” at the beginning of the second paragraph?
A．The study is conducted by researchers specializing in food and nutrition.
B．The study can deepen people’s understanding of the advantages of yeast.
C．The study has made great breakthroughs in finding what matters in bread.
D．The study shows you needn’t spend so much money on wholegrain bread.
【2】What can be concluded from the study mentioned in the passage?
A．Both white bread and nonwhite bread may do harm to our health.
B．People respond similarly to white bread but differently to nonwhite bread.
C．White bread and wholegrain bread produce no immediate effect on the body.
D．White bread eaters and artisanal bread eaters report different body responses.
【3】The findings need more research because of ________ .
A．the theory they are based on
B．the number of participants
C．the method of the experiments
D．the duration of the study
【4】Which of the following is the author most likely to agree with?
A．It’s better to stick to ancient ways of making bread.
B．Supermarkets should label the bread that may do harm.
C．There is no need to choose bread due to its ingredients.
D．Bread must be free of bacteria for the sake of our health.
23、When the world responded to the COVID-19 epidemic with broad lockdown orders, home delivery services lacked the manpower to keep up with the explosion in demand. Stores and companies went on doing the hiring; in some areas, it was very hard to get goods delivered.
You know what might have made things a bit easier? Drones. It has taken years for the Federal Aviation Administration (FAA) to allow the use of unmanned aerial devices for commercial delivery. Over the course of a decade, we've gone from a complete ban to slow, heavily regulated, and restricted initial testing.
At the end of August 2020, the FAA finally gave Amazon approval for its Prime Air drone delivery fleet. It did that by classifying Amazon as an "air carrier" and making it obey some relatively recent regulations intended to facilitate drone deliveries.
The FAA's rules initially required that private drones remain in sight of the operator at all times. That simply won't work for delivery services. So in 2019, the agency introduced a special certification process that would allow approved pilots to operate drones across much longer distances.
Amazon will now be able to join Google in drone deliveries. The company revealed that its fleet can carry packages weighing up to 5 pounds and deliver them within a 15-mile range in less than 30 minutes. The FAA also recently granted the company Zipline, a temporary waiver allowing it to deliver medical supplies in North Carolina. Zipline had been operating for some time in Africa. But the United States continues to fall behind both developed and developing nations in giving drone companies the freedom to test their services.
While Amazon still faces several technical problems and strict regulations, it's great that the government is giving it this new room to move. Too bad it took the feds this long to allow it, especially as the pandemic made drone deliveries not just an innovation, but something we could have used yesterday.
【1】What can be inferred from Paragraph 2?
A．Drones are the most convenient aerial devices.
B．The use of drones was completely banned at first.
C．It took a short time to allow the use of drones.
D．FAA allows drones to serve for the army.
【2】According to the passage, which of the following statements is TRUE?
A．Home delivery services were in great demand because of the COVID-19 epidemic.
B．Rules for private drones also works for delivery services.
C．Amazon's pilots were allowed to operate drones across much longer distances until 2020.
D．America took the lead in giving drone companies the freedom to test their services.
【3】What's Paragraph 5 mainly about?
A．The companies allowed to use drone delivery.
B．Amazon joining in drone deliveries.
C．Drone deliveries used in medical service.
D．Zipline operating in Africa and America.
【4】What's the author's attitude toward Amazon's drone delivery?
A．Neutral.
B．Negative.
C．Favorable.
D．Indifferent.
24、I believe that my country，Poland，is a perfect example for a place where food is particularly important. When we were little children, we began to understand how much a loaf of bread meant to our parents—to some it might sound silly but for me the custom of kissing bread before you started cutting it was simply amazing. It’s not so common nowadays to treat food that way，since you hardly ever bake your own bread. Besides, everyone would call you crazy if you tried to kiss every bread roll before you ate them! But though we no longer make our food from scratch (起点), some customs have been kept—that’s why I feel so sorry every time I have to throw any food away—even though I no longer live with my parents and nobody would blame me for this anymore!
Many people of our nation are still working as farmers, eating what they grow and harvest and therefore enjoying everything more. It’s widely known that you value more anything that needs your effort in the first place. In most homes in Poland, especially those of farmers, the whole family would try and have their meals together—extremely difficult now, but so rewarding! You can share other members’ troubles and successes, give your children some attention, or just sit down for a moment, instead of rushing through life aimlessly. Furthermore, your body，and stomach in particular will be very grateful for such a time!
In Poland, a wedding，Christmas or even a birthday is celebrated with a great meal. Women in the house get together and cook ,sometimes for a few days before the event，and the extremely good or unusual food will be remembered and widely talked about.
You cannot over-value the importance of food in the country. What’s more, almost everyone in Poland will be as interested in the topic as I am.
【1】When the writer was a child, he/she _______.
A. found people were crazy about bread
B. began to realize the importance of food
C. thought that cutting bread was amazing
D. learned people hardly baked their own bread
【2】The writer feels very sorry when he/she has to throw away any food because___________.
A. he/she makes food from scratch
B. his/her parents would blame him/her
C. some customs still have effect on him/her
D. many people are still working hard as farmers
【3】From the text, we can learn that, in Poland, ________.
A. most meals can be interesting topics for a long time
B. the whole family often have meals together nowadays
C. it’s common for women to get together to cook for a few days
D. family members can know more about each other by having meals together

26、阅读下列短文，根据其内容写一篇 60 词左右的内容概要。
Yours, Li Hua
“Stop the world, I want to get off!” This popular expression refers to a feeling of panic, or stress, that makes people want to stop whatever they are doing, try to relax, and become calm again. Stress is one of the most common causes of health problems in modern life. Too much stress results in physical, emotional, and mental health problems.
There are numerous physical effects of stress. Stress can affect the heart. It can increase the pulse rate, make the heart miss beats, and can cause high blood pressure. Stress can affect the respiratory(呼吸的) system. It can lead to asthma and cause a person to breathe too fast, resulting in a loss of important carbon dioxide. Stress can affect the stomach. It can cause stomachaches and problems of digesting food. These are only a few examples of the wide range of illnesses and symptoms resulting from stress.
Emotions are also easily affected by stress. People suffering from stress often feel anxious. They may have panic attacks and feel tired all the time. When people are under stress, they often overreact to little problems. For example, a normally gentle parent under a lot of stress at work may yell at a child for dropping a glass of juice. Stress can make people angry, moody, or nervous.
Long-term stress can lead to a variety of serious mental illnesses. Depression, an extreme feeling of sadness and hopelessness, can be the result of continued and increasing stress. Alcoholism and other addictions often develop as a result of overuse of alcohol or drugs to try to relieve stress. If stress is allowed to continue, then one's mental health is put at risk.
It is obvious that stress is a serious problem. It attacks the body. It affects the emotions. Untreated, it may eventually result in mental illness. Stress has a great influence on the health, our feelings, and our minds. So, reduce stress: stop the world and rest for a while.
