21、In my living room, there is a plaque (匾 ) that advises me to “Bloom(开花)where you are planted.” It reminds me of Dorothy. I got to know Dorothy in the early 1980s, when I was teaching Early Childhood Development through a program with Union College in Barbourville, Kentucky.The job responsibilities required occasional visits to the classroom of each teacher in the program.
Dorothy stands out in my memory as one who “bloomed” in her remote area.Dorothy taught in a school In Harlan County, Kentucky,Appalachian Mountain area.To get to her school from the town of Harlan, I followed a road winding around the mountain. In the eight-mile journey, I crossed the same railroad track five times, giving the possibility of getting caught by the same train five times.Rather than feeling excited by this drive through the mountains,l found it depressing. The poverty level was shocking and the small shabby houses gave me the greatest feeling of hopelessness.
From the moment of my arrival at the little school, all gloom(忧郁)disappeared. Upon arriving at Dorothy's classroom. I was greeted with smiling faces and treated like a queen. The children had been prepared to show me their latest projects.Dorothy told me with a big smile that they were serving poke greens salad and cornbread for “dinner”(lunch). In case you don't know, poke greens are a weed-type plant that grows wild, especially on poor ground.
Dorothy never ran out of reports of exciting activities of her students.Her enthusiasm never cooled down.When it came to time to sit for the acquired testing and interviewing to receive her Child Development Associate Certification(证书),Dorothy was ready.She came to the assessment and passed in all areas. Afterward, she invited me to the one-and-only steak house in the area to celebrate her victory, as if she had received her Ph. D. degree.After the meal,she placed a little box containing an old pen in my hand.She said it was a family heirloom(传家宝), but to me it is a treasured symbol of appreciation and pride that cannot be matched with things.
【1】In the journey, the author was most disappointed at seeing________.

C．the same train
D．the winding road
【2】Upon arriving at the classroom, the author was cheered up by________ .

A．She was invited to a celebration at a restaurant.
B．She got a pen as a gift from the author.
C．She passed the necessary assessment.
D．She received her Ph.D.degree.
【4】What does the author mainly intend to tell us?

22、How does an ecosystem(生态系统)work？What makes the populations of different species the way they are？Why are there so many flies and so few wolves？To find an answer，scientists have built mathematical models of food webs，noting who eats whom and how much each one eats.
With such models，scientists have found out some key principles operating in food webs. Most food webs，for instance，consist of many weak links rather than a few strong ones. When a predator(掠食动物)always eats huge numbers of a single prey(猎物)，the two species are strongly linked；when a predator lives on various species，they are weakly linked. Food webs may be dominated by many weak links because that arrangement is more stable over the long term. If a predator can eat several species，it can survive the extinction(灭绝)of one of them. And if a predator can move on to another species that is easier to find when a prey species becomes rare，the switch allows the original prey to recover. The weak links may thus keep species from driving one another to extinction.
Mathematical models have also revealed that food webs may be unstable，where small changes of top predators can lead to big effects throughout entire ecosystems. In the 1960s，scientists proposed that predators at the top of a food web had a surprising amount of control over the size of populations of other species---including species they did not directly attack.
And unplanned human activities have proved the idea of top-down control by top predators to be true. In the ocean，we fished for top predators such as cod on an industrial scale，while on land，we killed off large predators such as wolves. These actions have greatly affected the ecological balance.
Scientists have built an early-warning system based on mathematical models. Ideally，the system would tell us when to adapt human activities that are pushing an ecosystem toward a breakdown or would even allow us to pull an ecosystem back from the borderline. Prevention is key，which scientists says because once ecosystems pass their tipping point(临界点)，it is remarkably difficult for them to return.
【1】What have scientists discovered with the help of mathematical models of food webs？
A．The living habits of species in food webs.
B．The rules governing food webs of the ecosystems.
C．The approaches to studying the species in the ecosystems.
D．The differences between weak and strong links in food webs.
【2】A strong link is found between two species when a predator______
A．has a wide food choice
B．can easily find new prey
C．sticks to one prey species
D．can quickly move to another place
【3】What conclusion can be drawn from the examples in Paragraph 4？
A．Uncontrolled human activities greatly upset ecosystems.
B．Rapid economic development threatens animal habitats.
C．Species of commercial value dominate other species.
D．Industrial activities help keep food webs stable.
【4】How does an early-warning system help us maintain the ecological balance？
A．By getting illegal practices under control.
B．By stopping us from killing large predators.
C．By bringing the broken-down ecosystems back to normal.
D．By signaling the urgent need for taking preventive action.
23、 "The queuing delays are a tiny part of your total hours of life, so don't let them be a major source of anxiety," says Richard Larson, who has studied queuing for 40 years. Larson came up with mathematical methods for predicting what he calls slips and skips, where a newcomer arrives after you but gets the service first. Such cutting doesn't need to be intentional to feel unjust. “If you are the victim, you suffer a psychological cost," Larson says. “You can get angry or even violent" Just relax instead.
Larson has noticed more and more queues that allow people to buy their way into a faster lane. He's unsure whether that could change the culture of how Americans line up, but it might. A well- designed line makes cheating nearly impossible. If you find yourself in a long line, a queue to get hundreds of millions of people vaccinated (接种疫苗) for Covid-19, be patient. Don't try to cut ahead of others just because no one is standing behind you to see it.
While you wait, let yourself be distracted (分心) by a book, music or whatever occupies your mind. Sometimes, distraction is built in by designers. If you find yourself growing disappointed in a line, look behind you. The more people you see, the more likely you are to stay in line and maybe even be pleased with your position.
Sometimes great human experiences are shared while waiting in line. Larson recently got his Covid-19 vaccination. Normally, he tends to avoid queues, but he relished this one. Many around him were elderly, some in wheelchairs, some with helpers. There was excitement on their faces as they waited together, a lightness that only comes when fear begins to lift.
【1】According to Richard Larson, if faced with slips and skips, you should,
A．be overcome with unfairness.
B．solve the problem with violence.
C．cut in line without being noticed.
D．have a calm and peaceful mind.
【2】We can conclude from the passage that
A．the way that Americans queue up will be changed.
B．people never jump the queue in a well- designed line.
C．it is unnecessary to stay in line when you get vaccinated.
D．distraction can relieve anxiety of people in a long line.
【3】The underlined word "relished" in the last paragraph probably means
A．teased.
B．enjoyed.
C．reserved.
D．opposed.
【4】The passage is intended to answer the question
A．Why should you queue up in public places?
B．What are the reasons for jumping the queue?
C．What can you do while waiting in line?
D．How can queuing up be avoided?
24、For many young adults, what to do after finishing high school is a question that is not easy to answer. For some their path is clear, but for others a number of possibilities lie before them. 【1】 You are not too sure about the direction you want to take and would like to explore your options. Or maybe you have a desire to travel and experience other countries before settling down to further studies. 【2】 What to do during your gap year can be tailored to suit your needs, interests and budget. Let’s look at a few ideas that can just help you!
【3】 You can become a babysitter in your community or work on an oil field in another country. This can really help you to gain insight into yourself when you decide what you are passionate about. 【4】 Choosing a sporting adventure in another country, either playing or coaching will be an amazing experience. In addition, giving back to the community by volunteering in a local charity is also how you would like to spend your time.
From these experiences, you will learn much more than just how to do a job. Aside from your photographs, your most treasured possession will be that new experiences challenge you and allow you to grow. So whether you are going abroad or going to your local community center, one thing is for certain — a gap year is definitely not just filling a gap. 【5】
A．Perhaps you are one of the latter.
B．Why not apply for a job locally or abroad?
C．How about combining sports with learning?
D．You can find helpful information on some websites.
E．It is a year that can make all the difference to your future.
F．You will look back and know that your gap year has done that.
G．Whatever your reasons, a gap year can be an enriching and exciting time.
