You have to praise the smoothness（顺畅）of ants on the move. No matter how many of them are going toward a place, there's never a hold-up. A new research paper shows how ants keep traffic flowing by changing their behavior to meet changing conditions.
For their experiments, researchers from the University of Toulouse focused on Argentine ants, animals that often move from colony（群落）to colony depending on where the food is. Making use of Argentine ants' talent for fast travel, the researchers built bridges connecting their colonies. The bridges were different in width from a fifth to three-quarters of an inch. The colonies, too, were of different sizes, ranging from 400 to more than 25,000 ants.
Then the researchers sat back andmonitoredthe traffic. To their surprise, even when those narrower bridges were full of ants, there were no "traffic accidents". "When the number of ants on the bridge increased, ants seemed to be able to understand the situation and adjusted（调整）their speed accordingly to avoid making the traffic flow stop. "the authors note. "Moreover, ants avoided entering a busy road and made sure that the bridge was never too packed to cross.”
The lesson for humans? The traffic problem may lie in our inability to adjust our driving habits for the good of the whole. Driving is fun when there are few cars on the road. Then the traffic moves very slowly. And yet, some impatient driver still acts like he's alone on the road.
The research suggests that projects, like the ever-widening of highways, may never free us from traffic jams. As long as we drive along with our own habits, no matter how many other people are on the road, we'll always end up in a traffic jam. Indeed, less space may actually be a good thing. It leaves less room for individual choice and forces us to take a page from the driving book of ants.

The idea came to him when he least expected it. Alvin Irby was at a barbershop when he saw one of his former students sitting in the shop with a bored look on his face. That’s when Irby realized that by pairing barbershops and books, he might be able to inspire young boys to read.
Alvin Irby, a former kindergarten and first-grade teacher, knows how important it is for young children to read. He also knows that young boys in particular often don’t have adult male role models who inspire them to read. “Many young boys may literally never see a man reading in school during the years when they’re learning to read because there are so few male elementary school teachers,” Irby toldMashable.
That’s where the barbershops come in. Four years ago, Irby launched Barbershop Books as a way to not just get books into the hands of young boys, but also to create community reading spaces in a place where kids go frequently. Since itsinceptionin 2013, the program has created kid-friendly reading spaces in 50 barbershops in 12 states throughout the United States.
Irby isn’t the first person to see the connection between barbershops and books and boys. Hair stylist Courtney Holmes, launched a program a few years ago offering free haircuts to kids as long as they read to him while he cuts their hair.
That’s the kind of environment that Irby wants to promote with his program. The reading spaces created by Barbershop Books help to spark an interest in books by showing kids that reading is about more than just spelling and vocabulary skills, it’s about making reading a low-stress activity that can help them relax, laugh and have fun.
“Our belief is that if we can create positive reading experiences early and often for young boys, then they will choose to read for fun,” Irby noted, adding, “This is really what Barbershop Books is about, getting young boys to say three words: I’m a reader.”
4. What happened to Alvin when he was at a barbershop?
A. He found it easy for young people to get bored.
B. He offered a barbershop to his former student.
C. He thought of a way to encourage young readers.
D. He realized the importance of reading for young boys.
5. What is the function of Barbershop Books?
A. To attract more customers who love films.
B. To provide free haircuts to book lovers.
C. To show the influence of reading on children.
D. To create a reading environment fbr children.
6. It can be inferred from the passage that ________.
A. reading is a low-stress activity that is relaxing
B. Barbershop Books is only suitable for young boys
C. Irby attaches great importance to school education
D. Barbershop Books can arouse (引起) young people’s interest in reading
7. What does the underlined word “inception” in the 3rdparagraph mean?
A. discovery.
B. success.
C. popularity.
D. beginning.
C
14 days. That’s the time Chinese scientists took to identify the full genetic sequence of the novel coronavirus (新冠病毒) since its outbreak. It was shared with the WHO immediately, and has now become an important foundation for global researchers in the fight against the COVID-19. But first, let us turn the clock back 17 years, when it took months to identify the SARS virus. From months to 14 days, what changed? It turns out AI played an important part.
The scientists first obtained bronchoalveolar lavage (BAL) fluid (支气管扩张灌洗液) samples from patients, isolated (分离) the DNA and RNA, then sequenced the genetic material by comparing them. AI’s advantage is its ability to recognize patterns among a flood of data.
Let me put it in a simple way. Sequencing the coronavirus genome (基因组) is similarto looking for a needle in a haystack (干草堆)---looking for genotypes (基因型) with specific characteristics from a huge gene pool. That’s where search algorithm (算法), a branch of modern AI, comes in. Think of it as an efficient search engine, which can find the needle in the haystack. This search algorithm can shorten months-long genetic sequencing to weeks or even just a few days. Combined with macro-genomic sequencing and a virus library, this AI technology can also be used in tracking virus mutation (突变).
AI doesn’t just support scientists. It can also help patients by improving the efficiency of diagnosis (诊
断).Chinalaunched a Genomics Service, which can run multiple virus gene comparisons and produce a detailed report within 60 seconds. This algorithm hasbeen put into use inChinaand shared to the world for free.
8. AI’s advantage is that it can ________.
A. slow down the spread of coronavirus
B. separate DNA from RNA
C.identify specific genotypes rapidly
D. obtain samples from patients quickly
9. The search algorithm helps shorten the time of genetic sequencing by __________.
A. finding a needle in a haystack
B. serving as a search engine
C. combining with a virus library
D. tracing virus mutation
10. What do we know about the Genomics Service in the last paragraph?
A. It has been widely used in the world.
B. It is mainly based on blood test.
C. It is for fast diagnosis of COVID-19.
D. It is used to track COVID-19 patients.
11. What’s the best title of the passage?
A. 14 Days---ChinaMade it!
B. AI Assists in COVID-19 Fight
C. Search Algorithm, Best Choice
D. China’s Genomics Service
D
Who is a genius? This question has greatly interested humankind for centuries.
Let's state clearly: Einstein was a genius. His face is almost the international symbol for genius. But we want to go beyond one man and explore the nature of genius itself. Why is it that some people are so much more intelligent or creative than the rest of us? And who are they?
In the sciences and arts, those praised as geniuses were most often white men, of European origin. Perhaps this is not a surprise. It's said that history is written by the victors, and those victors set the standards for admission to the genius club. When contributions were made by geniuses outside the club—women, or people of a different color1 or belief—they were unacknowledged and rejected by others.
A study recently published bySciencefound that as young as age six, girls are less likely than boys to say that members of their gender(性别)are “really, really smart.” Even worse, the study found that girls act on that belief: Around age six they start to avoid activities said to be for children who are “really, really smart.” Can our planet afford to have any great thinkers become discouraged and give up? It doesn't take a genius to know the answer: ly not.
Here's the good news. In a wired world with constant global communication, we're all positioned to see flashes of genius wherever they appear. And the more we look, the more we will see that social factors(因素)like
gender, race, and class do not determine the appearance of genius. As a writer says, future geniuses come from those with “intelligence, creativity, perseverance(毅力), and simple good fortune, who are able to change the world.”
12. Whatdoes the author think of victors' standards for joining the genius club?
A. They're unfair.
B. They're conservative.
C. They're objective.
D. They're strict.
13. What can we infer about girls from the study inScience?
A. They think themselves smart.
B. They look up to great thinkers.
C. They see gender differences earlier than boys.
D. They are likely to be influenced by social beliefs
14. Why are more geniuses known to the public?
A. Improved global communication.
B. Less discrimination against women.
C.Acceptance of victors' concepts.
D. Changes in people's social positions.
15. What is the best title for the text?
A. Geniuses Think Alike
B. Genius Takes Many Forms
C. Genius and Intelligence
D. Genius and Luck

The easy way out isn't always easiest. I learned that lesson when I decided to treat my father to a special meal. I glanced through the cookbook and chose a menu which included homemade bread. Knowing the bread would take time, I started on it as soon as he left for work.
As I was not experienced in cooking, I thought if a dozen was good, two dozen would be better, so I doubled everything. As Dad loved oranges, I also opened a can of orange and poured it all into the bowl. Soon there was
sticky dough (面团) covered with ugly yellowish marks. Realizing I had been defeated, I put the dough in the rubbish bin outside so I wouldn't have to face him laughingat my work.
I went on preparing the rest of the meal, and, when Dad got home, we sat down to Cornish chicken with rice. He tried to enjoy the meal but seemed disturbed. Twice he got up and went outside, saying he thought he heard a noise. The third time he left, I went to the windows to see what he was doing.
Looking out, I saw Dad standing about three feet from the rubbish bin, holding the lid up with a stick and looking into the container. When I came out of the house, he dropped the stick and explained that there was something alive in the rubbish bin. Picking up the stick again, he held the lid up enough for me to see. I felt cold. But I stepped closer and looked harder.
Without doubt it was my work. The hot sun had caused the dough to double in size and the. fermenting yeast (酵母) made the surface shake and sigh as though it were breathing. I had to admit what the "living thing" was and why it was there. I don't know who was more embarrassed by the whole thing, Dad or me.
