A Book Review—The Snake-Stone by Berlie Doherty
The setting: Urban England (the cities), but also rural England (the countryside) including remote English villages. The theme: The main theme is a teenage search of self-discovery, in this case the search for a mother from whom the hero was separated at an early age. Its other concerns are love, getting on with others, being persistent and courageous and trying to deal with doubts, troubles and worries. As the book moves to a close, James’ swimming coach says to him: “You are not like a kid obeying instructions any more. You are diving like a young man who knows where he is going.”
The characters: James is the hero of the story. He is a championship diver, and has a comfortable life with his foster parents (养父母). Yet he also has the qualities to take him on a long journey to find his birth mother. The other characters in The Snake-Stone, James’ parents, his diving instructor, best friend, the villagers, people he meets on his journey, are pictured realistically.
The turning point:The turning point in the story comes while James’ foster parents are away in London, and he wonders about the identity of his birth mother. The only clue he has is a fossil, “the snake stone” which she left behind along with a note on which she had wri tten: “Take good care of Sammie.” It was written on a torn envelope with parts of an address still there.
The journey: Instead of going to London, James decides to find his birth mother. With help from his geography
teacher, James sets out for the remote country village where his mother might be found. James has painful, challenging, but also humorous and happy travels. The mother he finally meets, Anne, has a minor yet powerful voice in the novel. He comes to understand why she left him at a stranger’s doo r fifteen years before. Although the meeting is not long, it leaves him with a feeling of completeness. As a journey of self-discovery, The Snake-Stone also provides its readers with a happy ending. Its hero says, on re turning to his foster parents, “I was home.”21．What is the main theme of the novel?
A．Life with foster parents. B．Life in the world of diving.
C．A journey of self-discovery. D．A travel around the country.
22．What do the coach’s words in P aragraph 2 suggest?
A．James is a successful diver. B．James is an independent young man.
C．James is an outgoing young man. D．James is a hopeful swimmer.
23．The snake stone in the novel is .

Some people believe that a Robin Hood is at work, others that a wealthy person simply wants to distribute his or her fortune before dying. But the donator who started sending envelopes with cash to deserving causes，accompanied by an article from the local paper, has made a northern German city believe in fairytales.
The first envelope was sent to a victim support group. It contained €10,000 with a cutting from t he Braunschtveiger Zeitung about how the group supported a woman who was robbed of her handbag; similar plain white anonymous (匿名) envelopes, each containing €10,000, then arrived at a kindergarten and a church.
The envelopes keep coming, and so far at lea st €190,000 has been distributed. Last month, o ne of them was sent to the newspaper’s own office. It came after a story it published about Tom, a 14-year-old boy who was severely disabled in a swimming accident. The receptionist at the Braunschweiger Zeitung opened an anonymous white envelope to find 20 notes of €500 inside, with a copy of the article. The name of the family was underlined.
"I was driving when I heard the news.”Claudia Neumann, the boy’s mother, told DerSpiegel magazine.“I had to park on th e side of the road; I was speechless.”
The money will be used to make the entrance to their house wheelchair-accessible and for a course of treatment that their insurance company refused to pay for.
“For someone to act so selflessly, for this to happen in such a society in which everyone thinks of himself, was astonishing," Mrs. Neumann said. Her family wonder whether the donator is a Robin Hood character, taking from banks to give to the needy.
Henning Noske, the editor of the Braunschweiger Zeitung, said:“Maybe it is an old person who is about to die. We just do not know.” However, he has told his reporters not to look for the city’s hero, for fear that discovery may stop the donations.
24．The Braunschweiger Zeitung is the name of_____________ .
A．a church B．a newspaper
C．a bank D．a magazine
25．Which of the following is TRUE about the donation to Tom?
A．The donation amounted to €190,000.

C．His mother felt astonished at the donation.
D．The money will be used for his education.
26．It can be inferred from the passage that____________.
A．the donation will continue to come
B．the donator is a rich old man
C．the donation comes from the newspaper
D．the donator will soon be found out
27．What would be the best title for the passage?
A．Money Is Raised by the Newspaper
B．Newspaper Distributes Money to the needy
C．Robin Hood Returns to the City
D．Unknown Hero Spreads Love in Envelopes

Pangolins (穿山甲) are the most trafficked (非法交易) mammals in the world and are facing extinction. To draw attention to these scaly (有鳞片的), anteater-like animals, a new wildlife documentary, Eye of the Pangolin, is attempting a unique way to inspire action and conservation. Partnering with the non-profit organization Pangolin Africa, the documentary was made available on YouTube in May 2019. The intention is to reach communities wherever the Internet is available, especially African communities, who live near the animal’s habitats.
Over two years, the documentary crew traveled to South Africa, Ghana, Central African Republic and Gabon in search of the four unique species of pangolin, which has never been achieved before. Filmmakers Bruce Young and Johan Vermeulen say that they went into the shoot knowing relatively little about pangolins, but grew to respect and appreciate the animals. Getting close to the creatures over two years was a crash course in these secretive creatures. Johan Vermeulen said, "One thing however that might seem unimportant is that they are actually quite fussy eaters. You would think they would eat any type of ant, but they all prefer a specific type ant."
Pangolins are hunted illegally across Africa for their scales, which are used for traditional medicine, and their meat. In April 2019, Singaporean customs officials conducted two separate seizures of 24 tons of pangolin scales,
which equals to the death of 69,000 pangolins.
Though the documentary focuses less on the trafficking of pangolins, and more on the animals in their natural habitat, the aim of the documentary is to inspire viewers around the world to call for action to end trafficking and protecting these unique creatures.
Filmed on location in South Africa, Ghana, Central African Republic, and Gabon, this powerful documentary is the story of two men on a mission to get all four species of African pangolin on camera for the very first time. 28．What is the purpose of the documentary?
A．To study the situation of pangolins.
B．To raise awareness of pangolin protection.
C．To collect fund to protect pangolins.
D．To propose setting up pangolin reserves.
29．What is the meaning of the underlined word “fussy” in paragraph 2?
A．picky. B．messy. C．showy. D．heavy.
30．What’s the documentary mainly about?
A．The illegal trade of pangolins.
B．The medical function of pangolin's scales.
C．The efforts of Pangolin Africa to save pangolins.
D．The life of pangolins in their natural habitats.
31．Where is the text most likely from?
A．A brochure. B．A diary. C．A magazine. D．A novel.
D
You know the saying “You’re as young as you feel." Well, there may be some truth to that, according to researchers at Harvard and the Massachusetts Institute of Technology.
Ellen Langer, a Harvard psychologist who studies how the mind influences the body, and colleagues reviewed the scientific literature for evidence that a person’s perception of their age might influence their health. They published their results in the journal Perspectives on Psychological Science.
In one study that Langer led, 47 women had their hair done. The women who thought their new hairdos made them look younger did look younger to objective observers, who were shown before-and-after pictures. The women who thought they looked younger also showed a drop in blood pressure. Another study involving 4,421 men found that those who became bald at a relatively young age were more likely to get cancer and heart disease than men who did not. Similarly, another study involving 2,017 men found that those who lost their hair early were more likely to develop heart disease. “We believe that the feelings associated with being older than one’s real age account
for some of these health outcomes,” the researchers wrot e.
The researchers also described studies that found that women who had children later in life were more likely to be healthier and live longer than those who had children early, which they attributed to the fact that these mothers tend to spend more time with younger women. Similarly, people who marry younger partners tend to live longer than those who marry older partners, according to other studies.
Taken together, the research “supports the general mind-body hypothesis (假说) that when a younger mind is prepared, a younger body can accompany it.” While the mechanism(机制) remains unclear, the researchers figured that suggestions associated with aging can “make one unconsciously or consciously aware of old age and set in motion a series of physiological processes that can have real effects on short-term and long-term health."
32．What’s the author’s attitude towards the research results?
A．Negative. B．Indifferent. C．Supportive. D．Objective.
33．Which of the following statements is true according to paragraph 3?
A．Blood pressure is highly related to hairdos.
B．Getting cancer or heart disease is the cause of hair losing.
C．Feeling older than real age may be tied to health problems.
D．The women who love hairdo s look younger than those don’t.
34．It can be inferred from Paragraph 4 that ________.
A．often staying with younger people can benefit people's health
B．the younger one of a couple lives much longer
C．a younger mother is more likely to live longer
D．people who want to live longer need to marry
35．The passage mainly tells us that ________.
A．Getting bald too early is not good for health
B．People’s feeling of their age may have an effect on their own health
C．Feeling younger to a couple is very important to their health
D．Women had better give birth later in their life
第二节（共5小题；每小题2分，满分10分）
根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
If you take a look around your kitchen or office right now, chances are that you’ll notice you’re surrounded by plastic—water bottles, to-go coffee cups, straws, plastic grocery bags, food wrappers, take-out containers, single-serve coffee pods and produce bags. 36 ．
It’s certainly not realistic to remove all plastic from your life, but let’s examine some statistics that may
encourage you to reduce your single-use plastic footprint by throwing away straws, switching to reusable water bottles, bringing cloth bags to the grocery store and more.
According to a study published in the journal Science Advances, the popularity of plastic, which began rising in the 1950s, is growing out of control. 37 ．And there’s no sign of slowing down, considering scientists say that another 12 trillion kilograms will be produced worldwide by 2050.
“Every piece of plastic that has ever been created will remain in the environment in some form, but once we conveniently throw out our rubbish at home, wind and runoff carry our waste from landfills and streets to the ocean,” says Mystic Aquarium’s chief clinical veterinarian Jennifer Flower, DVM, MS. “Given that we are globally producing over 320 million tons of plastic annually, the marine environment is taking a big hit from our daily disposal of plastic.
38 ．For example, newborn fish are mistaking tiny bits of plastic waste for food. If they die, there will be fewer big fish—and that could damage the food chain. Often our society is so focused on making our lives more convenient in the short term, but in the long run, our health and the health of marine life are at the expense of those everyday conveniences.”
39 ．A recent report suggests that when heated, certain food additives (添加剂) can damage hormones, growth and development, as well as increase chances for children of being fat.
40 ．It is found in plastic containers and metal cans. Parents are urged to avoid using microwaves to warm food and drinks or placing plastics in the dishwasher.
A．Using plastic containers in microwaves is also harmful to child ren’s health.
B．Our plastic consumption is directly affecting the life in the ocean.
C．8.2 trillion kilograms of plastic have been produced around the world.
D．People are concerned about the results of overusing plastic containers.
E．Let’s stop using plast ic for the benefit of the environment and human beings.
F．The most concerning artificial additive BPA is a chemical used in the production of plastics.
G. These are all examples of single-use plastic products, which is a hot topic nowadays.

The mascot(吉祥物) for the 2022 Winter Olympic Games official made its public appearance on Tuesday. It was a cartoon character inspired by giant pandas. The smiling panda is named with Bing Dwen Dwen in Chinese. Color circles around its face symbolize skating tracks and 5G technology.

第二节书面表达
Dear Mike,
I'm more than delighted to receive your letter and really appreciate your concern about my family's health at this very moment. I'm writing to tell you about what we've done and how I feel.
Over the past three months, the novel coronavirus has spread around China. As a
consequence, we're required to stay indoors and avoid contact with others. Every time we have to go out, we must wear protective masks. When coming back from outside, we should wash hands thoroughly and air the room. In
addition, as senior three students, we're instructed to take online courses conducted by our teachers who also selflessly answer our questions after class, improving our study.
For us Chinese, the ongoing outbreak of the novel coronavirus is both a crisis and a big test. Luckily, with arduous work and courageous devotion of the government and thousands of doctors and nurses, the outbreak is under control and the number of infected people is steadily declining. With joint efforts, we will surely defeat it.
Looking forward to your early reply.
