    My name is Leo. I never thought of myself as a special person, but I always dreamed to be a superhero like Batman and Superman.
    One morning, I awoke, slipped out of bed and looked out of the window. There was a world covered in a sea of white snow. I hurried to get dressed and set out to take a walk in the snow with my drone (无人机).
    When I wandered in the park near my home, I saw the frozen river lying there peacefully. Then, a young girl came into my sight. She ran happily, followed by her mom from a distance. Suddenly, she was so excited that she accidentally rushed to the ice on the river. There was a creak (嘎吱声) and the girl, sensing something wrong, said "Mommy!" just before the ice gave way. With a splash (落水声), the young girl crashed through the ice. At that moment two things happened to me. Firstly, I stood more alertly (警觉地) than I had ever been before in my life. Secondly, I was on the move.
    I didn't know what overcame me but I needed to help. The precious drone in my hand crashed to the ground and was crushed by me as I ran. I threw off my jacket and scarf while running, knowing they would weigh me down. As the woman yelled "Help!" at passers-by, I was already moving across the ice to get the girl. I tried to pull her up but the ice further broke and I fell in too. As the water began to make me very cold to the bone, I thought only of the young girl. I grasped her under the arms and pushed her up onto the ice near the edge. I was of almost no help so the mother reached out and pulled her daughter into her arms.
    "Take her. So c-c-c cold." I said as I pushed the girl upwards.
    The woman turned back to help me using the scarf but I was nowhere to be seen. Blackness enveloped me.
    With a start I awoke! There were firemen all around me and I was lying in the snow with a mask on my face. Cheers broke out around me. My life really changed. It was a spirit and it did come to me because I was a true hero.

    Most environmental pollution comes from humans and their inventions. The electric bulbs are thought to be one of the greatest human inventions of all time. However, too much of a good thing has started to negatively impact the environment. Light pollution, the extreme or inappropriate use of outdoor artificial light, is affecting human health and wildlife behavior. There is a global movement to reduce light pollution, and everyone can help.
    Light pollution is a global issue. This became particularly obvious when the World Atlas(地图册) of Night Sky Brightness, a computer-generated map based on thousands of satellite photos, was published in 2016. Vast areas of North America, Europe, the Middle East, and Asia are glowing with light, while only Siberia, the Sahara, and the Amazon are in total darkness.
    Artificial light can wreak havoc on natural body rhythms in both humans and animals. It interrupts sleep and confuses the circadian rhythm(生理节奏)—the internal, twenty-four-hour clock that guides day and night activities and affects physiological processes in nearly all living organisms. One of these processes is the production of the hormone melatonin (褪黑素), which is released when it is dark and is prevented when there is light. An increased amount of light at night lowers melatonin production, which results in lack of sleep, headaches, stress, anxiety, and other health problems. Blue light, in particular, has been shown to reduce levels of melatonin in humans. It is found in cell phones and other computer devices, as well as in light-emitting diodes (LEDs), the kinds of bulbs that have become popular at home and in industrial and city lighting due to their low cost and energy efficiency.
    Studies show that light pollution is also impacting animal behaviors, such as migration (迁徙) patterns and habitat formation. Because of light pollution, sea turtles guided by moonlight during migration get confused, lose their way, and often die. Large numbers of insects, a primary food source for birds and other animals, are drawn to artificial light and are instantly killed upon contact with light sources. Even animals living under the deep sea may be affected by underwater artificial lighting. One study looked at how animals in sea responded to brightly lit panels put under water off the coast of Wales. Fewer filter feeding animals (滤食性动物), such as the sea squirt (海鞘), made their homes near the lighted panels. This could mean that the artificial light is altering ocean ecosystems.
    The good news is that light pollution, unlike many other forms of pollution, is reversible (可逆的) and each one of us can make a difference! Now, many people are taking action to reduce light pollution and bring back the natural night sky. Individuals are urged to use outdoor lighting only when and where it is needed, to make sure outdoor lights are properly shielded (遮挡) and direct light down instead of up into the sky, and to close window blinds, shades, and curtains at night to keep light inside.
19. What does the underlined phrase "wreak havoc on" in Para.3 probably mean?
A. Greatly improve. B. Well maintain.
C. Strictly manage. D. Seriously damage.
20. According to the passage, which would the author agree with?
A. Light pollution was first studied as a global issue in 2016.
B. Deep-sea environment can help animals avoid light pollution.
C. Artificial light affects the sense of direction and habits of animals.
D. LEDs can be used more because of low cost and energy efficiency.
21. What is the author's attitude towards the control of light pollution?
A. Unconcerned. B. Negative. C. Neutral. D. Positive.
22. What is the main purpose of the passage?
A. To call on people to reduce light pollution.
B. To discuss fors and againsts of artificial light.
C. To give suggestions to protect environment.
D. To show development prospect of artificial light.

    There are hundreds of bacterial (细菌的) species in our stomach. Bacterial diversity is a good thing, a general contributor to and marker of good health. But what does a healthy stomach look like? Studies indicate that the composition varies by many factors.
    One of the most important, it turns out, is who you currently live with. Researchers have come to the conclusion: Diet and heritability(遗传力) are known to affect the microbiome(微生物组), but social relationships shape it most—especially when it comes to marriage. The Dutch Project, which studied microbes in 8, 208 individuals belonging to three generations, finds that the heritability of microbes is only 1.9 percent. They noticed much greater similarity among the unrelated individuals sharing a household than among relatives who do not share households, including twins whose living situations differ in adulthood.
    The researchers found that nearly 50 percent of microbial types were significantly affected by cohabitation. In general, the microbiomes of all types of cohabitors (including parents and children) were more similar than those of participants living separately no matter their relatedness. Married couples who report having a close, loving relationship have the most similarity. Evidence of microbial sharing, especially of rare species, shows exchanges through interactions. And that puts highlight on acts of close relationship—including kissing. Scientists have known for decades that social relationships, especially marriage, powerfully affect health. Not only are the microbiomes of cohabiting couples more similar to each other; they also are more similarly diverse. There is a greater richness of species than in unmarried, non-cohabiting individuals.
    Despite the dominating influence of a close, cohabiting relationship, the microbiome can be different in diet, especially one rich in plant fiber. It can also be influenced by behavior, such as farming and gardening and exercise. Moreover, it's adaptable to environment—green space and pollutants around you. Living in a rural environment brings increases in bacteria linked to health, and decreases in bacteria that are harmful. Living with pets also has a positive effect on the microbiome, while exposure to air pollution, especially car exhaust, and passive exposure to cigarette smoke have negative effects.
    It can also be affected by direct addition of specific species of bacteria, delivered in consumable probiotics (口服益生菌). There are probiotics now marketed for digestive health, others aimed at immune health, and still others for boosting mood. Now that it's clear that social relations play the largest role in the makeup of the microbiome, can probiotics for singles be far behind?
23. Which group has the most similar microbiomes?
A. Husband and wife. B. Adult twins.
C. Grandfather and grandson. D. Colleagues.
24. What can we learn from this passage?
A. Diet has a dominating influence on microbiomes.
B. Cohabitation is helpful for us to have a balanced diet.
C. Social relations play a similar role as some probiotics.
D. The microbiomes in couples are less diverse than singles.
25. Which would be the best title for the passage?
A. Who Are the Healthiest People？
B. How Does Social Life Affect Our Health？
C. What Will a Healthy Stomach Look Like？
D. How Do Microbiomes Work in Our Body？
    A Nervous Journey    Let's take a journey. It is going to be a fast one, so be prepared. Where are we going? We are going to start at your head and end up at your toes.   (1)   It may be the shortest and fastest trip of your life. Are you ready? Let's begin. Wiggle your big toe. Okay, we're done. You might be saying, "That's it?" We said it was going to be a fast ride!
    You just sent a message with an electrical signal from your brain to the muscles in your toe. Bingo! It moves.   (2)   The electrical signals in your body can move as fast as 150 meters per second. In the amount of time it takes you to say "Mississippi" three times, a nerve could send an electrical signal the length of a football field and back. Now that you know how fast a nerve impulse (神经冲动) can travel, let's take a look at the system that is the highway for these electrical signals.
    The human body is made of trillions of tiny cells. Each cell is so small that you need a microscope to see them. Your skin, your hair, your eye—all are made up of cells.   (3)   Muscle cells move your body. Skin cells protect your body. One special type of cell, neurons (神经元), allow your brain to send messages to every part of your body.
    The center of the nervous system is the brain. The brain takes in what your eyes see and what your ears hear.   (4)   You can think of your nervous system as a relay team passing a baton from one runner to the next. But instead of runners, you have cells, and instead of a baton, you have information.   (5)   It hands its information to the next cell, which passes the information to another cell. In the end, the information reaches its destination and causes a change—maybe a muscle contracts. The "information" baton passed from neuron to neuron is usually a small electrical event called an action potential.
A.Just how fast was the signal moving?
B.A neuron in your brain starts the relay.
C.Different types of cells do different jobs.
D.You might have heard them called brain cells.
E.Did you ever wish you could go inside someone's brain?
F.It may not seem like a long trip, but it is going to be fast.
G.If you decide that you want to move around, your brain tells your muscles to do it.

31.     About five years ago, I was part of a pilot group tasked with helping the disabled be successful inside the organization. My boss decided to be the sponsor for the pilot and he was very kind. Until then we had only hired people with visually challenged disability.
    I led the interview process and hired a candidate with autism (自闭症). The candidate had the qualifications but our interview panel felt the disability would prevent him from learning the skills and being competent for a job. I convinced my peers (同伴) to give him a role, and try out. He finally was hired as a temporary contractor.
    I gave the candidate a lot of encouragement and became one of his mentors (导师). He slowly and surely blossomed in the workplace. There were many difficulties and barriers along the way. But he tried his best to overcome all the challenges his disability brought him with my help, which deeply moved his colleagues and leadership. Gradually, he came to be accepted by them. He too won many friends and admiration at the workplace.
    Fast forward five years, he called me last night to let me know that he got a formal offer yesterday from his manager as a regular employee with a job title. I congratulated him and told him my joy. He went on to say "Sir, without your support all these years, I would not be here." I told him "Your success is the reward of your hard work and persistence. You are an inspiration to a lot of people with similar disabilities."
    Isn't it wonderful that a person with disability is becoming very successful in a workplace and makes his family so proud?
(1) What was the task of the pilot group?
​​​​​​​_______________________________________________
(2) Why didn't the interviewers want to hire the candidate?
_______________________________________________
(3) Please decide which part is false in the following statement, then underline it and explain why.
The candidate gradually came to be accepted by his colleagues and leadership because he managed to make friends with them.

1. 根据第三段中的It interrupts sleep and confuses the circadian rhythm(生理节奏)—the internal, twenty-four-hour clock that guides day and night activities and affects physiological processes in nearly all living organisms.（它会干扰睡眠，扰乱昼夜节律——几乎所有生物体内指导昼夜活动并影响生理过程的24小时生物钟。）和下文提到的人造光对人类和动物造成的危害可知，人造光会打扰睡眠，扰乱生理节律，对人类和动物产生危害，结合划线短语所在句子Artificial light can wreak havoc on natural body rhythms in both humans and animals.（人造光可以对人类和动物的自然节律______。）可知，人造光可以对人类和动物的自然节律造成严重破坏。即划线短语wreak havoc on意思与D项“严重损害”意思一样，故选D。
2. 根据第四段中的Studies show that light pollution is also impacting animal behaviors, such as migration (迁徙) patterns and habitat formation. Because of light pollution, sea turtles guided by moonlight during migration get confused, lose their way, and often die.（研究表明，光污染也影响动物的行为，如迁徙模式和栖息地的形成。由于光污染，在月光引导下的海龟在迁徙过程中容易迷路，甚至死亡。）可知，人造光影响动物的方向感和习性。故选C。
3. 根据最后一段中的The good news is that light pollution, unlike many other forms of pollution, is reversible (可逆的) and each one of us can make a difference!（好消息是，光污染，不像其他形式的污染，是可逆的，我们每个人都可以做出改变！）可知，光污染是可逆的，每个人都可以做出改变。即作者对光污染控制的态度是积极乐观的。故选D。
4. 根据第一段中的Light pollution, the extreme or inappropriate use of outdoor artificial light, is affecting human health and wildlife behavior. There is a global movement to reduce light pollution, and everyone can help.（光污染，极端或不适当的使用户外人工光，正在影响人类健康和野生动物的行为。有一个减少光污染的全球运动，每个人都可以帮忙。）可知，文章主要介绍了人造光对人类和动物的危害，呼吁我们要行动起来，减少光污染，所以文章的写作目的是A（呼吁人们减少光污染。），故选A。

23~25.【答案】A、C、C
【解析】【文章大意】本文是一篇说明文，文章介绍了一个健康的胃的组成是有很多不同的因素。
1. 根据第二段中的Researchers have come to the conclusion: Diet and heritability(遗传力) are known to affect the microbiome(微生物组）, but social relationships shape it most—especially when it comes to marriage. （研究人员得出结论：饮食遗传力已知会影响微生物组，但社会关系影响最大，尤其是婚姻关系。）以及They noticed much greater similarity among the unrelated individuals sharing a household than among relatives who do not share households, including twins whose living situations differ in adulthood.（同住一个家庭的无血缘关系的个体之间的相似性比不同住一个家庭之间的无血缘关系的亲属之间的相似性要大得多）可知，丈夫和妻子的关系会具有相似的微生物群。故选A。
2. 
根据最后一段中的Now that it's clear that social relations play the largest role in the makeup of the microbiome, can probiotics for singles be far behind?（既然社会关系在微生物的构成中起着重大的作用，那么单身者们的益生菌还会远吗？）可知，社会关系和一些益生菌都在微生物的构成中起着重要作用，由此可推知，社会关系和一些益生菌有着相似的作用。故选C。
3. 
结合文章第一自然段（我们的胃里有数百种细菌。细菌多样性是一件好事，是健康的总体贡献者和标志。但是健康的胃是什么样子的呢？研究表明，成分因许多因素而异。）可知，本文介绍了一个健康的人的胃受到各种因素的影响，因此C（健康的胃会是什么样子？）最适合做文章标题，故选C。

【解析】1. 【文章大意】本文是一篇记叙文。文章主要讲述了作为小组成员之一的作者帮助残疾人在组织内取得成功的故事，告诉我们帮助残疾人成功是一件很美妙的事情。
由本文第一段中的About five years ago, I was part of a pilot group tasked with helping the disabled be successful inside the organization.（大约五年前，我是一个试点小组的一员，该小组的任务是帮助残疾人在组织内部取得成功。）可知试验组的任务是帮助残疾人在组织内取得成功，故答案为The task of the pilot group is to help the disabled be successful inside the organization.

Gradually, he came to be accepted by them.（但在我的帮助下，他努力克服了残疾给他带来的一切挑战，这让他的同事和领导深受感动。渐渐地，他被他们接受了。）可知因为他设法和他们成为了朋友这句话是错误的。这位候选人逐渐被他的同事和领导层接受，是因为他在我的帮助下尽力克服了残疾给他带来的所有挑战，这深深打动了他的同事和领导者，故答案为The candidate gradually came to be accepted by his colleagues and leadership because he managed to make friends with them.
The reason that the candidate gradually came to be accepted by his colleagues and leadership is that he tried his best to overcome all the challenges his disability brought him with my help. This deeply moved his colleagues and leadership.
