21、What happens when we experience emotions?
In brief, emotional responses have four parts. There is a bodily (physiological) response, an interpretation in the mind, feelings, and an effect on behaviour. These do not happen in any special order - they happen at the same time and affect each other. 【1】
To understand the physiological response, imagine you are frightened by an aggressive, noisy dog. Your brain sends messages throughout your body. It does this by releasing a chemical called adrenaline, which the blood carries to other parts of the body. Then, the bodily sensations of being frightened begin. Blood drains from your stomach (giving a feeling we describe as a "knot in the stomach"). The blood vessels（血管）in the face become narrower (which makes you become white). Similar processes exist for other emotions. 【2】 This helps the person get ready for a fight.
The second aspect of emotion is interpretation in the ind of events and feelings. This is both conscious and unconscious. In fact, the more you think about the dog, the more frightened you become. Thinking like this sends both your feelings and your physical arousal to new heights.
【3】 In one, the brain senses the body's state of arousal. The other comes from memories of your body's reactions in similar situations in the past. So, when you see the angry dog, your brain may remember your feelings from past experiences with angry dogs.
Finally, emotions can also affect behavior. 【4】 In this, the person either becomes aggressive or runs away. Responses may also include facial expressions and sounds, such as crying, screaming or shouting. There may also be gestures, such as waving arms.
A．The “feeling” aspect of emotions comes from two sources.
B．We will illustrate this process with the most carefully studied of all emotions: fear.
C．In response to the aggressive dog, this could be the so-called "fight-or-flight" response which appears to be part of our biology.
D．We should make clear, however, that emotions are not completely fixed by our biology.
E．With anger, for example, more blood flows to the hands, and more energy is released.
F．Fear, for example, undoubtedly helped people thousands of years ago to respond to dangerous situations.
22、 When you walk with a backpack, you know how the belongings inside swings from side to side? Now scientists have figured out how to make use of that movement to generate electricity.
Here's how it works. Imagine a pendulum fixed to a backpack frame and fixed with springs on either side. The pack's weight is attached to the pendulum, so the pendulum swings side to side as you walk. Gears then use that swinging motion to drive a generator, and the generator release electrical current to charge a battery.
Volunteers carried the pack while walking on a running machine and wore masks to measure the flow of oxygen and carbon dioxide. Walking with the slightly swing 20-pound load, the device did not significantly affect the volunteers' metabolic rate compared to when they carried the same weight fixed in place. In fact, the energy-harvesting pack reduced the forces of speeding up force they'd feel in a regular pack, which might mean greater comfort for a long hike. And the device did produce a steady trickle of electricity—the key word being trickle.
Because if you up the load to 45 pounds, the passive motion of the pack could fully charge a Samsung Galaxy S10 smartphone only after 12 hours on the way. The details are in the journal Royal Society Open Science.
But here's the backpack difficulty: the energy-harvesting device currently weighs five pounds. The researcher say that's about four pounds too many to be a smart alternative to batteries. So they hope that more research lets them lighten the load, to ensure the pack charges you up without weighing you down.
【1】What does the passage mainly talk about?
A．The working theory of a new electrical device.
B．The working theory of a backpack generating electricity.
C．The discovery of using a backpack's movement to generate electricity.
D．The advantages and disadvantages of using a backpack to generate electricity.
【2】What other benefit does the backpack have?
A．losing weight.
B．charging a device.
C．saving money.
D．walking comfortably.
【3】Which of the following is most relevant to the amount of electricity?
A．walking distance.
B．load weight.
C．swing time.
D．moving speed.
【4】Why is there difficulty of carrying the backpack?
A．The generator is too heavy.
B．The electricity is too low.
C．It takes too much time.
D．The electricity isn't steady.
23、 When it comes to modern communication, security is a big concern. It seems like we’re forever hearing about hackers leaking(泄露) emails, passwords and other important personal information.
But thanks to a breakthrough by Chinese scientists, who won the 2018 Newcomb Cleveland Prize in February, we may soon never have to worry about our data again. This is thanks to the satellite called Micius that uses cutting-edge technology to send and receive information.
Micius is the first satellite of its kind to use quantum key distribution(量子密匙分发), which uses particles (粒子) that transmit(传输) light to transfer information from one point to another. Currently, it can communicate with two base stations(基站), both of which are located high up in the mountains in two different areas of Tibet, around 1,200 kilometers apart. Data is sent between the satellite and one of the base stations in the form of a ray of light. This makes it almost impossible for data sent and received using quantum satellite technology to be stolen, as the connection will be broken if someone tries to hack it.
“Any eavesdropper(偷听者) on the quantum channel attempting to gain information … can be found by the communicating users,” the scientists wrote in the paper.
However, the technology does have a few limitations. For example, the process only works at night, as the information isn’t able to pass through sunlight.
Despite these small issues, the scientific community across the world has reacted positively to China’s achievements in this groundbreaking project.
“This Chinese experiment is a quite remarkable technological achievement,” Artur Ekert, a professor of quantum physics at the University of Oxford, told BBC News.
And Karl Ziemelis, an editor for Nature, told Xinhua, “It’s a testament(见证)to China’s investments and significant efforts in the physical sciences that this group has been able to push research in practical quantum communication technologies to such an astronomical(天文学的)height.”
【1】According to the passage, why Micius is safe for transporting messages?
A.Because it is only data base located in space, which cannot be touched.
B.Because it only works at night, as the information isn’t able to pass through sunlight.
C.Because it uses particles that transmit light to transfer information from one to another.
D.Because it doesn’t score any important private information like passwords and e-mails.
【2】Which of the following can best describe scientists’ words in the paper?
A.It gave out the working principle of Micius.
B.It tells of a kind of scientific appearance.
C.It warned hackers not to steal information from Micius.
D.It is a more apparent explanation of its safety.
【3】What’s the main problem of Micius?
A.Its core technology is controlled in foreign countries.
B.Light is a must in its working process.
C.Its safety performance needs improving.
D.Sunlight has a deadly influence on its working.
【4】What’s the best title of the passage?
A.Leaping into an age of secure data
B.How should you avoid information hackers
C.Old Problem, New Approaches
D.Taking on data theft
24、My son Daniel's love for surfing began at the age of 13. After school he wore his wet suit, walked out beyond the surf line and waited to be challenged by his three-to six-foot companions. Daniel's love of the ride was tested one fateful afternoon.
“Your son’s been in an accident,” the lifeguard (救生员) reported over the phone to my husband Mike. “When he surfaced to the top of the water, the point of the board was heading toward his eye.” Mike rushed him to the emergency room. He received 26 stitches (针) from the corner of his eye to the bridge of his nose.
I was on an airplane flying home from a speaking arrangement while Dan's eye was being stitched. Mike drove directly to the airport after they left the doctor's office. He greeted me at the gate and told me Dan was waiting in the car, “Daniel?” I questioned. I remember thinking the waves must have been awful that day. “He's been in an accident, but he's going to be fine.” A traveling working mother's worst nightmare had come true.
I sobbed telling Daniel how awful I felt about not being there when the lifeguard called. “It's okay, Mom,” he comforted me. “You don't know how to surf anyway.” “What?” I asked, confused by his reason, “I'll be fine. The doctor says I can go back in the water in eight days.” Was he out of his mind? For the next seven days he kept pressing me to let him go back on the board. One day after I repeated “No” to him for the 100th time, he said, “Mom, you taught us never to give up what we love.” I gave in.
I was tested in my own backyard on an important principle that I teach audiences in distant cities: Passionate (热情的) people hug what they love and never give up .

26、阅读下列短文，根据内容写一篇60词左右的内容概要。
Almost all Americans are involved with sports in some way. They may play baseball or volleyball or go swimming or skiing. They may watch football or basketball on the high school, college, or professional level. In reality, sports have reached a point where they play too large a role in daily life.
The overemphasis (过度强调) on sports can be seen most obviously in the vast media coverage of athlete events. It seems as if every race, meet, or match is shown on one television channel or another. In addition, sports news make up about 30 percent of local news. Radio offers a complete list of games and a wide variety of sports shows. Furthermore, many daily papers such as USA Today are devoting more and more space to sports coverage, often in an attempt to attract more readers. The paper with the biggest sports section is the one people will buy.
The way we raise and educate our children also illustrates our sports craziness. As early as six or seven, kids are placed in little leagues, often to play under screaming coaches and pressuring parents. Later, in high school, students who are selected by the school and the community are not those who are the best academically but those who are the best athletically. And college sometimes seems to be more about sports than about learning. The United States may be the only country in the world where people often think of their colleges as teams first and schools second. The names Penn State, Notre Dame and Southern Cal mean “sports” to the public.
Our sports craziness is especially evident in the prestige (声望) given to athletes in the United States. For one thing, we reward them with enormous salaries. In 1990, for example, baseball players averaged 350,000 a year; the average annual salary in the United States is 18,000. Besides their huge salaries, athletes receive the admiration, and sometimes the votes of the public.
