21、Through an analysis of fMRI brain scan images taken from 138 people, the new artificial intelligence algorithm(算法) achieved an accuracy rate of over 99 percent in detecting potential indicators of Alzheimer’s(老人痴呆症). In particular, the method is able to pick out signs of mild cognitive impairment or MCI(轻度认知障碍) —which is the step between cognitive decline (as normally associated with aging) and Alzheimer’s. Often, MCI won’t come with any physical symptoms that can be spotted. However, it’s also important to note that MCI doesn’t always necessarily mean Alzheimer’s—but it’s an important potential indicator of the disease in the future.
While human analysis of fMRI scans for signs of MCI can well adapt to various situations, humans are nowhere near as fast or reliable as deep learning techniques, which learn from vast databases of training data, then apply that knowledge to new data in intelligent ways.
“Of course, we don’t dare to suggest that a medical professional should ever rely on any algorithm 100 percent. Think of a machine as a robot capable of doing the most tedious task of sorting the data and searching for features, ” says Rytis Maskeliūnas, an professor from the Kaunas University of Technology (KTU) in Lithuania.
Once the computer software has highlighted potential cases, specialists can then review and confirm them. An earlier diagnosis means earlier treatment, even if we’re yet to discover a way of stopping Alzheimer’s completely.
“Although this was not the first attempt to diagnose the early onset of Alzheimer’s from similar data, our main breakthrough is the accuracy of the algorithm, ” says Maskeliūnas.
Various methods are used to detect Alzheimer’s right now, including eye tracking, voice analysis, and even the installation of sensors in people’s homes—but AI methods like the one outlined in this new study promise to be faster and simpler.
【1】What do we know about MCI?
A．It can be identified by AI algorithm.
B．It can be easily discovered by people.
C．It is certainly caused by a certain disease.
D．It brings about apparent physical changes.
【2】What is an advantage of human analysis of fMRI scans?
A．More reliable.
B．More accurate.
C．Much faster.
D．More flexible.
【3】What’s author’s attitude to AI methods in identifying Alzheimer’s?
A．Doubtful.
B．Neutral.
C．Uncertain.
D．Favorable.
【4】Which can be the best title for the text?
A．AI Gained a New Function in Health Care
B．AI Can Offer Early Treatment for Alzheimer’s
C．AI Can Identify Signs of Alzheimer’s with High Accuracy
D．Modern Technologies Are Helpful in Protecting Our Health
22、Life lessons from death
Living gratefully has a huge transforming power, not just when something wonderful or special happens, but every day no matter what is happening. I've recently been involved with two people whose lives were challenged by bad luck. I have seen how grateful living had the power to keep one of them going and how it's beginning to lift the other. One was a friend and the other is my sister.
My friend seemed to be in good health when she received a deadly diagnosis（诊断）: a disease with no effective treatment. She had all the emotions that a tragedy（悲剧）brings, but she also had a powerful response to despair（绝望）that gave her " the happiness that doesn't depend on what happens." She wrote online daily, honestly sharing the details of her situations.
She wrote that even though it was difficult to move, this gave her more time to notice small things. She was grateful not only for the love and help of family and friends, but also for time to see the sun rise and watch the birds in her yard. No opportunity for gratefulness was wasted.
She taught that gratefulness is not a false cheerfulness. It's taking every opportunity to celebrate the blessings of small things. We can be grateful for the challenge that helps us develop compassion（同情）for each other. Life is a precious gift.
She repeatedly blogged（写博客）that she was happier than she had ever been. When she wrote about "the worst day", she ended with "Life is still a lovely gift." She died later that day.
Her message, however, changed my sister's life. My sister's health was getting worse and worse, though nothing life-threatening（威胁生命的）. She did have a very painful knee. Her life was in danger form her defeated spirit She was bed-bound（卧床不起）, getting weaker and weaker. Fearful, angry and depressed, she felt out of options for recovery.
I read my sister a few of my friend's messages. I was careful not to say, "Why can't you be more like her? " Instead, I let the words do their work. I'm grateful to say that an attitude of gratitude began to replace her anger and fear. I believe this helped her to heal.
We can't be grateful for all that happens, but we can practise gratefulness for life itself, for all we can learn to deal with, for all the ways we can help each other grow and heal.
【1】How did the author's sister feel when she was ill?
A．Calm
B．Lonely
C．Sad
D．Confused
【2】What happened when the author's friend found she had an incurable disease?
A．She complained that life was unfair to her.
B．She started to appreciate and enjoy the small things in life.
C．She tried her best to look for the best doctors.
D．She repeatedly blogged how painful it was.
【3】What does the underlined word "this" refer to in the passage?
A．Writing a blog
B．Eating healthy food
C．Talking with family
D．Being grateful for life
【4】What message does the passage mainly convey?
A．A friend in need is a friend indeed.
B．Gratitude has the power of lifting people's spirits.
C．Health is the most important thing for people.
D．Families will always be there no matter what happens.
23、From now on, never spend your precious time thinking of reasons for your failures and shortcomings. Instead, realize that the seeds of success were planted within you when you were born. Only you have the power to make those seeds grow.
The seeds, and the power to grow them, are contained in the most awesome (令人惊叹的) machine ever created: the human mind. Success is a choice and not a chance. You were born a winner. You were born rich. You can be a success if only you make the right choice.
You cannot be successful without first developing your self-esteem (自尊). Your level of self-esteem is always based on the degree of control that you are able to exercise over yourself, and thus over your life. People with low self-esteem are people who do not believe that they have any power, or responsibility for their lives. They are leaves tossed(摇摆)by the winds of chance blown about with any sudden change in the weather.
You can exercise control over your life only to the degree that you believe that you are responsible for everything that happens in your life. Failures think that everything happens by accident and chance. Successful people realize that they are responsible.
Everything happens as a result of something. If we can identify the cause, we can control the effect. We are responsible for what we choose to think and believe. One generally rises to the level that one expects. We are responsible for setting our expectations. Our success is dependent upon our level of confidence.
If you associate with positive-thinking people, you are definitely going to achieve success. On the contrary, the opposite happens. We are responsible for finding, planting, and nurturing (养育) the seeds that contain future victory, born from setbacks (挫折).
In short, in all areas of your life, whether they be financial, physical, emotional, or spiritual, you are responsible. Once you recognize this, accept it, and firmly believe it, you are on the road to success.
【1】People with low self-esteem are compared to leaves because they ______.
A．are ready to change their minds
B．don’t have the ability to control themselves
C．can’t be successful with self-control
D．are easily affected by windy weather
【2】Losers would think that ______.
A．their failure is accidental
B．working hard will lead to success
C．they are responsible for success
D．they should make efforts to succeed
【3】It can be inferred from paragraph 5 that ______.
A．our success results from our attitudes
B．one can rise to the level that one expects
C．we should be responsible for our thoughts and beliefs
D．setting our expectations is essential before taking action
【4】The last paragraph serves as ______.
A．the proof of the author’s points

D．a comparison between two views
【5】Which is the best title for the text?

26、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。
One day, my brother and I were coming back from the islands where we often risked going and got more fish than others. All at once, the sky was covered with dark clouds and in less than a minute we were in a terrible storm. A huge wave covered our boat and we nearly fell into the sea. My brother put his mouth close to my ear and cried out “Moskoe-strom!” The moment I heard the word I became very frightened. I knew what he meant by that one word well enough.
With the wind and waves, we were going in the direction of the whirlpool (漩涡). We were hopeless. Nothing could save us. I felt sick, as if I was falling from a mountain top in a dream. We went round and round, nearer and nearer to the horrible edge of the whirlpool. It may appear strange, but at that moment, when we were on the edge of the whirlpool, I felt calmer than when we were moving towards it. I began to think how amazing a thing it was to die in such a way, and how wonderful it was to see the power of nature. Suddenly, we went over the edge. I thought my life was over. But moment after moment passed, and I was still safe.
The boat was on the inside of the huge whirlpool and we were going round in circles at great speed. I saw clearly that there were other objects in the whirlpool—trees and barrels (水桶). After a while, I became curious about the whirlpool itself. I then made three important observations. The first, the larger the bodies were, the more rapidly they fell; the second, between two objects of equal extent, round objects fell down less rapidly; and the third, between two objects of the same size, objects shaped like a tube fell down more slowly. So I tied myself to a barrel to help me float. I tried to make my brother understand, but he was too frightened and stayed in the boat. Without waiting, I jumped into the sea to try and escape.
注意：1.所续写短文的词数应为150左右；
2.请按如下格式在答题卡的相应位置作答。
Paragraph 1:
Some time after I left the boat, I saw my brother struggling in the sea.
______________________________________________________________________________________________________________________________________________________________________________________________
Paragraph 2:
Soon after that, the whirlpool became less wild and then the sky was clear.
