A
I truly thought thatI might die that day. Had I not seen three bears and a few wolves over the last couple of days near the road, I might have just lain down and called it quits. What in the world was I thinking, dragging my bike up to Yellowstone and thinking I could ride from West Yellowstone to Old Faithful in the snow? No less!
I had planned this trip for more than two months, and I wasn't about to give up so easily. The first few miles were beautiful. Ten miles in, I started sucking wind. Fifteen miles and my legs felt like they were made of lead. By twenty miles, my lungs were burning and felt like there was nothing left in the tank. That was when I turned around and saw my husband and three children cheering me on in the van behind me. I knew I couldn't quit because I tell my children all the time that just because something is hard doesn't mean that you stop doing it. I had to live what I'd been preaching(说教). That thought got me up that mountain and to the end of the ride.
The importance of that ride was apparent after only a week. My eight-year-old daughter Emalee wanted to ride in a twelve-mile charity ride. That day was cold as well. She was the youngest rider. About four miles into the ride, she started feeling cold. The chill(寒冷)was making her muscles cramp a little and she began to struggle. By six miles, she had tears running down her face. It broke my heart to see her suffering like that.I told herthat she didn't have to finish. She said that she wouldn't quit. I told her how I had wanted to quit the week before, but perseverance had gotten me to the end and I knew she could do it, too.
The look on her face as she pulled into the finish was priceless. She threw her arms around me and said, “You didn't quit, Mommy, so neither did I.”
1. What motivated the author to finish her ride?
A. Her family's encouragement.
B. Her own instruction for children.
C. The beautiful scenery and weather.
D. The careful and thorough preparation.
2. By describing the conditions Emalee met, the author wanted to________.
A. show her guilt for her daughter
B. prove that riding is a tough task
C. persuade her daughter to give up
D. indicate she was proud of Emalee
3. What does the author want to tell us according to the story?
A. Never say die.
B. Do nothing by halves.
C. Children are what the mothers are.
D. Every mother's child is handsome.
B
Identifying the chemical makeup of pigment (色素) used in ancient documents, paintings, and watercolor1 s is criticalto restoring and conserving the precious artworks. However, despite numerous efforts, scientists had been unable to determine the source of folium, a popular blue dye used to color1 manuscripts (手稿) in Europe during the middle ages — from the 5th to the 15th century. Now, a team of researchers fromPortugalhas finally uncovered the mysterious ingredient responsible for the gorgeous blueish-purple color1 that helped bring ancient illustrations and texts to life.
The research team began byporing overinstructions penned by European dye makers from the 12th, 14th, and 15th centuries. They found what they were seeking in a 15th-century text entitledThe Book on How to Make All the Color Paints for Illuminating Books. However, translating the instructions was no easy task. It was written in the now extinct Judaeo-Portuguese language, and though the source of the dye was traced back to a plant, no name was mentioned.
However, by piecing together suggestions from the text, the scientists were able to determine that the dye was made from the bluish-green berries of the chrozophora tinctoria plant. After an extensive search, the team found a few varieties of the plant growing along the roadside near the town ofMonsarazin southPortugal.
The detailed instructions gave the researchers critical clues — including the best time to pick the berries. “You need to squeeze the fruits, being careful not to break the seeds, and then to put them on linen (亚麻).” The scientist says the detail was important since broken seeds polluted the pigment, producing an inferior quality ink. The dyed linen, which was left to dry, was an efficient way to store and transport the pigment during ancient times. When needed, the artist would simply cut off a piece of the cloth and dip it with water to squeeze out the blue color1 .
Once the key ingredient had been identified, the researchers began to determine the dye’s molecular structure. To their surprise, they found that folium was not like any other known permanent blue dyes — it was an
entirely new class of color1 , one they named chrozophoridin. “Chrozophoridin was used in ancient times to make a beautiful blue dye for painting.” the team wrote in the study. “Thus, we believe that this will not be our final word on this amazing plant and its story and that further discoveries will follow soon.”
4. The primary purpose of the study is to ________.
A. restore and conserve ancient precious artworks
B. determine the substance making up the folium
C. prove the ancient dye-making technique was organic
D. identify which class of color1 folium belongs to
5. The underlined phrase “poring over”in the second paragraph means ________.
A. discussing publicly
B. testing repeatedly
C. passing directly
D. reading carefully
6. What can be learned about the blue dye folium?
A. It was essentially an inferior type of ink.
B. It was the only kind made from wild berries.
C. It could be carried and used easily.
D. It was carefully squeezed from broken seeds.
7. The article is mainly about _________.
A. how the mystery ofa thousand-year-old blue dye was solved
B. why the researchers took the trouble to recreate the dye
C. what needs to be done to make an organic dye from a plant
D. when and where the discovery of the dye was made
C
Bill Gates on how to fight future pandemics
WHEN HISTORIANS write the book on the covid-19 pandemic, what we've lived through so far will probably take up only the first third or so.The bulk of the story will be what happens next.
I believe that humanity will beat this pandemic, but only when most of the population is vaccinated(接种疫苗）.Until then, life will not return to normal.
As the pandemic slows in developed nations,itwill accelerate in developing ones.Their experience,however,will be worse.In poorer countries,where fewer jobs can be done remotely,distancing measures won't work as well.The virus will spread quickly,and health systems won't be able to care for the
infected.
Wealthy nations can help.But people in rich and poor places alike will be safe only once we have an effective medical solution for this virus,which means a vaccine.
My hope is that,by the second half of 2021,facilities around the world will be manufacturing a vaccine.If that's the case,it will be a history-making achievement: the fastest humankind has ever gone from recognizing a new disease to immunizing（免疫）against it.
Apart from this progress in vaccines,two other big medical breakthroughs will emerge from the pandemic.One will be in the field of diagnostics.The next time a novel virus crops up,people will probably be able to test for it at home.Researchers could have such a test ready within a few months of identifying a new disease.
The third breakthrough will be in antiviral drugs.We haven't been as effective at developing drugs to fight viruses as we have those to fight bacteria.But that will Researchers will develop large diverse libraries of antivirals,which they'll be able to scan trough and quickly find effective treatments for novel viruses.
All three technologies will prepare us for the next pandemic by allowing us to intervene(干预）early when the number of cases is still very low.
Our progress won't be in science alone.It will also be in our ability to make sure everyone benefits from that science.In the years after 2021,I think we'll learn from the years after 1945. With the end of the Second World War, leaders built international institutions like the UN to prevent more conflicts.After covid-19, leaders will prepare institutions to prevent the next pandemic.
These will be a mix of national,regional and global organizations.I expect they will participate in regular"germ games”in the same way as armed forces take part in War games.These will keep us ready for the next time a novel virus jumps from bats or birds to humans.
I hope wealthy nations include poorer ones in these preparations,especially by devoting more foreign aid to building up their primary health-care systems.This pandemic has shown us that viruses don't obey border laws and that we are all connected biologically by a network of microscopic germs,whether we like it or not.
The best analogy(类比）for today might be November 10th 1942.Britainhad just won its first land victory of the war,and Winston Churchill declared in a speech: “This is not the end.It is not even the beginning of the end.But it is,perhaps,the end of the beginning.”
8. What are the three technologies that will prepare us for the next pandemic?
①manufacturing a vaccine fast
②diagnosing a virus at home
③developing antiviral drugs
④allowing us to intervene early
A. ①②③
B. ①②④
C. ①③④
D. ②③④
9. As far as poorer countries areconcerned,which of the following is TRUE according to this passage?
A. pandemic disease is more likely to begin in poorer countries
B. Working from home can work well in poorer countries.
C. Health systems are sufficient to care for the infected in poorer countries.
D. Virus will cross borders if poorer countries fail to contain it.
10. Why is the Second World War mentioned in Para.8?
A. The fight against the COVID-19 is similar to the Second World War.
B. People are suffering just as they were in the Second World War.
C. We should cooperate globally just as we did after the Second World War.
D. Countries are fighting each other like in the Second World War.
11. What is the tone of this passage?
A. pessimistic
B. optimistic
C. neutral
D. indifferent
D
In the northern part ofAustin there once lived an honest family by the name of Smothers. The family had John Smothers, his wife and their five-year-old daughter.
One night after supper the little girl was ill with a serious stomachache, and John Smothers hurried downtown to get some medicine. He never came back. The mother was very sad over her husband's disappearance, and it was nearly three months before she married again, and moved to San Antonio. The little girl recovered and in time grew up to womanhood. After a few years had rolled around, the little girl also married in time, and she also had a little girl of five years. She still lived in the same house where theydweltwhen her father had left and never returned.
By an unbelievable coincidence her little girl was taken with the same stomachache on the same night of the disappearance of John Smothers, who would now have been her grandfather if he had been alive. “I will go downtown and get some medicine for her,” said John Smith(for it was he whom she had married). “No, no, dear John,” cried his wife. “You, too, might disappear forever, and then forget to come back.” So John Smith did not go,
and together they sat by the bedside of little Pansy. After a little while Pansy seemed to grow worse, and John Smith again wanted to go for medicine, but his wife would not let him.
Just then, the door suddenly opened and an old man with long white hair entered the room. “Hello, here is grandpa,” said Pansy. She had recognized him before any of the others. The old man drew a bottle of medicine from his pocket and gave Pansy a spoonful. She got well immediately. “I was a little late,” said John Smothers, “as I waited for a street car.”
12. What happened after John Smothers disappeared?
A. His daughter took some medicine.
B. His wife left for San Antonio.
C. Pansy immediately had a stomachache.
D. John Smith went for medicine.
13. What does the underlined word “dwelt” in paragraph 2 probably mean?
A. Lived.
B. Left.
C. Returned.
D. Married.
14. What is the relationship between John Smothersand Pansy?
A. Husband and wife.
B. Father and daughter.
C. Grandfather and granddaughter.
D. Father and son.
15. How could Pansy's mother feel when she saw John Smothers?
A. Worried.
B. Sad.
C. Uninterested.
D. Surprised.

What Are the Roots of Your Self-Esteem?
Self-esteem is a person's subjective assessment of his or her worth to himself or herself. Self- esteem covers various beliefs about oneself (such as 'Tm a failure" and "I'm beautiful") as well as physiological states, including sadness, joy, and shame. The more we believe that we are worthy of happiness and good things in life, the more self-fulfilled we will be. When we don't believe that we are worthy of these things, our ability to enjoy them can suffer.____16____
Healthy self-esteem as an adult can be a gift given in your childhood. It is a blessing that most people overlook. There are so many ways adults with high self-esteem were supported as children that resulted in them having high self-esteem. For instance, they were praised for what they had achieved.
____17____They likely experienced affection and were given enough attention. It is also possible that they excelled in studies or in sports and were admired for it by peers.
____18____As children, many of these people were criticized, yelled at, or abused in one way or another.
There is also a high chance that they were given no attention by the adults who were supposed to care for them. In some cases, adults with poor self-esteem were often ridiculed for their shortcomings or bullied by peers.
It is common that these adults also believe that in order to be appreciated they need to be perfect.
____19____There are people who are obsessed with their careers or hobbies because in their mind they need to tie their worthiness to something concrete. Oftentimes these people have to pretend to be something they are not just to get approval.
How you feel about yourself impacts how you live your life. People with high self-esteem tend to have better relationships than those with low self-esteem.____20____So if you struggle to reach out for assistance, it could be rooted in your low self-esteem.
A.There is also a good chance that they were spoken to respectfully.
B.When we start to doubt what's important in life, we tend to do less of it.
C.Since self-esteem is connected to how we perform, it is important to work on it.
D.People with poor self-esteem, on the other hand, often experienced the opposite.
E.This creates an image in their mind that without accomplishment they are worthless.
F.They face failure too, but they understand that failure or success doesn't define them.
G.High self-esteem enables you to ask for help and support from the people around you when you need it.

When I was a very young children, my father created a regular practice I remember well years late. Every time he arrived home at end of the day, we’d greet her at the door. He would ask who we was and pretend not to knowing us. Then he and my mother would have had a drink while she prepared dinner and they would talk about
his day and hers. While they chat, my father would lift my sister and me up to sit in the top of the fridge. It was both excited and frightening to be up there! My sister and I thought he was so cool for putting us there.
第二节书面表达（满分25分）
52.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。

I grew up in a large family of twelve siblings（兄弟姐妹）.We weren’t poor by most standards, but things were definitely tight for us. My parents never shared their financial worries. Instead, they chose to let us have a carefree childhood. But despite their consideration, I knew, as children often do, that there were times they went without and that certain things my friends had wouldn’t be available to me.
Back in those days, hot lunch was a luxury for the wealthier kids, and hot-lunch buyers sat separately from the students who brought cold lunch. My siblings and I brought lunch from home every day: thick slices of homemade bread hiding one scant slice of bologna, three oatmeal cookies, and a small apple. We would look on longingly as the rich kids proudly sat down with their steaming plates of fried chicken or fish sticks and potato puffs, cartons of cold milk, chilled peaches and a slice of cake.
I never said anything, but my first grade teacher, Mrs. Caruso, must have seen the desire in my eyes. One day she quietly pressed a note into my hand and whispered, “Give this to your mother.”
I skipped home and gave my mom the note. She read it and smiled. “Well, Mrs. Caruso said because of all your hard work, she wants to buy your lunch tomorrow.” The next day, I proudly carried my tray of chicken fricassee across the cafeteria and took my seat at the hot-lunch table. Honestly, the food wasn’t as great as I had imagined, but I was pleased to be there and felt honored to be a part of the group.
One rainy day, Mrs. Caruso asked me to stay after school. My stomach instantly dropped to the floor. Surely, I must be in trouble! Did she know I hadn't finished my math sheet? Did she see me teasing Billy on the playground?
注意：
1.续写词数应为150左右；

After the other students had left, Mrs, Caruso said she was going to finish her work and then drive me home. _____________________________________________________________________________________________ _____________________________________________________________________________________________ ____
