21、Earlier this week, I wrapped up (圆满完成) a 5-day trip in San Francisco. I woke up a few hours before sunrise, drove through the darkness and out of the city, hiked for 30 minutes to the top of a hill overlooking the Golden Gate Bridge, and snapped(拍摄) this photo. As I stood there soaking in the early morning light, I was reminded of an important lesson.
When I arrived in San Francisco, I told myself, “Just take photos as you do other things.” My primary goal was to meet with friends and so I figured I could take pictures as we walked around the city. This resulted in exactly zero photos worth sharing. I had vague ideas like, “I’d like to do some street photography,” but I never went out with the intent of photographing something specific. Finally, on the last morning, I went out with the intent of capturing a specific picture and I ended up with something worth sharing. My mistake was that I assumed that because I wanted to take photos, I would end up getting a desirable result.
How often do you do this in your own life? We go to the gym to “work out” without trying to become better at something specific. We wish that we were more creative, but never work on a particular project. When you commit to a task, however, then the next step is obvious. You want to take a picture of the Golden Gate Bridge at sunrise? Next step: find a good spot. You’ve found a good spot? Next step: wake up early and drive there.
This is perhaps the most shocking thing: if box yourself in, then you’ll begin to break out and achieve something greater than you ever imagined.
【1】What’s the author’s original purpose of the trip?
A. To take pictures. B. To attend lessons.
C. To visit friends. D. To enjoy sunrise.
【2】What lesson did the author learn?
A. A given task leads to achievement.
B. Stick to your own decision.
C. Get ready for challenges.
D. Hard work pays off.
【3】What are you advised to do first when you want to get stronger physically?
A. Make a detailed outline.
B. Go to work out immediately.
C. Discuss the ways with coaches.
D. Choose a certain muscle group.
【4】What’s the function of the last paragraph?
A. To introduce a new topic.
B. To draw a conclusion.
C. To make a suggestion.
D. To ask readers to reflect on something.
22、 Human activities are killing wildlife at an alarming rate, with causes ranging from environmental pollution to the built environment. For bird species, nighttime collisions (碰撞) with power lines are driving significant population decline. But now scientists have come up with a clever way to make the lines easier for birds to spot, without being ugly to humans.
Industry and U. S. Fish & Wildlife Service guidelines recommended that electricity companies mark their power lines with plastic attachments to make it more visible, but birds were still dying. Biologists reported that 300 Sandhill cranes (鹤) perished in one month in 2019 from collisions with marked lines at the Rowe Sanctuary ‘in Nebraska, where the cranes stopped over during their annual spring migration. “We need forward-thinking methods to protect not only large birds that are naturally at greater risk from power lines but also millions of smaller birds,” said Anne Lacy of the, International Crane Foundation.
Bird species can see ultraviolet light (紫外线) at night. So James Dwyer, a wildlife biologist at a consulting firm, EDM, had the idea of using near-visible UV light to brighten power lines. EDM’s engineering team and the Dawson Public Power District developed such light systems and installed them on a tower supporting a power line at Rowe Sanctuary. Over a 38-night period, crane collisions decreased by 98 percent when the lights were on, the researchers reported in a study published online in May in Ornithological Applications.
Richard Loughery, director of environmental activities at the Edison Electric Institute, who was not involved in the project, says the new UV system adds an important tool for use in hotspots where endangered bird species nest and feed.
“I don’t want electricity companies to build lines wherever they want because there’s a new tool,” says biologist Robert Harms of the U. S. Fish &. Wildlife Service, who was not involved in the work. But for existing lines, he says, the UV system could be absolutely amazing.
【1】Why was the first method abandoned to protect birds?
A.It couldn’t protect birds migration.
B.It couldn’t prevent birds from standing on the plastic attachment.
C.The used material was hard for birds to spot at night.
D.The used material made more birds come to the power line.
【2】What does the underlined word “perished” in paragraph 2 mean?
A.Died. B.Appeared. C.Survived. D.Increased.
【3】What was the main reason for choosing UV light to protect birds?
A.It was more economical.
B.It was not harmful to birds.
C.It was invisible to people but not to birds at night.
D.It was a new technology tool for protecting birds.
【4】What did Robert Harms think of the UV system?
A.Unnecessary. B.Satisfactory. C.Critical. D.Skeptical.
23、 Winters were bitterly cold in my memory. You had to bundle up just to keep warm when you went outside. You were often cold, wet, slip on the ice, and you’d arrive home to an ice-cold house. And that would mean turning on the heating and waiting. It’s a miracle you didn’t get cold to the bone.
Fortunately, things don’t have to be so challenging any more. Technology, engineering and design have advanced, giving us new solutions to old problems. It means dealing with winter needn’t be like skating on thin ice.
With a smart thermostat (温度自动调节器), our homes can be warm when we need them to be. Many models feature smartphone apps that allow you to control temperature remotely, so we can warm up the house before we arrive home. According to techradar.com, Tado’s model features voice control, while the Nest “knows” your habits and automatically heats the home for you.
Clothes have been given an upgrade, too. Electronic thermal jackets, sweaters and coats heat up when you turn them on. At the touch of a button, or through an app on our phones, the clothing produces heat from the equipment placed inside. Many models offer three levels of heating which stay warm for over 12 hours.
Finally, there is the clothing for the head, Beanies and Earmuff, which feature speakers included in the fabric using Bluetooth technology so we can listen to our favourite music or, in some cases, have a phone call using the in-built microphone. All keep the head warm while avoiding a cold.
For many, the thought of winter used to be enough to make their blood run cold. But using technology, life needn’t freeze up. With the right solutions, there’s no reason why winter can’t be really, really cool.
【1】What do the underlined words “bundle up” mean in Para.1?
A.Fix an air conditioner. B.Take a hot bath.
C.Dress up. D.Put on more clothes.
【2】How does electronic thermal clothing work?
A.It needs to be warmed up before being used.
B.The equipment placed inside the clothing produces heat.
C.The thermostat heat up automatically when the temperature is low.
D.It keeps warm for over 12 hours after being charged for an hour.
【3】Which of the following is NOT true?
A.With technology, it takes only half an hour to warm up houses after users arrive home .
B.Tado’s model can be controlled by saying something to it.
C.With the in-built microphone, Beanies and Earmuffs users can have a phone call.
D.Bluetooth technology is used in the clothing for the head.
【4】What’s the best title of this passage?
A.A Smart Thermostat B.Ways of keeping warm
C.A Modern winter D.An unpleasant winter
24、“Today, technical innovations dominate our everyday life in many areas. New technologies, however, always are associated with risks -- and these are also seen by laymen,” says Christoph Böhmert, first author of the recently published study and researcher of the Science Communication Group of KIT’s Institute for German Studies. “It is crucial to enable adequate communication between science and society, which does not only consider scientific findings, but also concerns of the population.” The study clearly showed that communication of risks may be complicated sometimes. Information on efficient precautions was found to lead to an increased risk perception by the recipients of the information.
In their study, the researchers analyzed communication about a technology that has become indispensable in our life -- mobile communications and the electromagnetic fields （电磁场）on which it is based. All over the world, radiation protection authorities, such as the German Federal Office for Radiation Protection, communicate the current state of research into risks of electromagnetic fields as follows: Investigations made and all findings obtained so far do not allow any conclusions to be drawn with respect to mobile communications being a risk for human health. But, the experts continue, there still are knowledge gaps as regards long-term impacts. Then, measures are recommended to reduce exposure of the individual to electromagnetic fields.
It had been known from previous studies already that information on precautions may increase worries. It had been suspected that people conclude from the recommendation of precautions that there really is a risk. This effect was not confirmed by the recent study. The scientists rather attributed the increased worries to a lack of knowledge about the propagation(传播) of electromagnetic fields.
Within the framework of the study, the recommended precautions were submitted to 1717 Australians, together with one of six information brochures providing scientific background information. When test persons were given not only the recommendations, but also explained why observation of these tips strongly reduces their exposure to electromagnetic fields, worries increased. For example, scientists explained to the test persons that telephone conversations with a headset largely reduce exposure. When a mobile phone is located ten centimeters instead of just one centimeter away from the ear, the electric power absorbed by the ear is about one hundredth of the initial value. Hence, the own mobile phone usually causes an exposure that by far exceeds that of mobile communications stations that are generally referred to as “cellphone towers.” While the scientists wanted to explain the effectiveness of precautions, test persons mainly considered this information to be an indication of their mobile phone -- not the transmission towers -- being dangerous. As a result, they perceived increased risk potentials for telephone conversations with their mobile phones.
“The study reveals that messages on precautions and information are a double-edged sword in terms of subjective risk perception. Their use should be far better understood,” Boehmert says.
【1】Which of the following statements is TRUE according to the passage?
A. Adequate information on efficient precautions can relieve the concerns of the public.
B. Information about technologies and their risks may have undesired side effects.
C. Mobile communications definitely do harm to people’s health in the long run.
D. Observation of the precautions can help reduce the concerns of the public.
【2】According to the passage, we can conclude that the best way to relieve the inappropriate worries is to __________.
A. inform the public about the potential risks with more patience
B. produce new electric products with a lower radiation value
C. provide the public with less information on effective precaution
D. enable the users to know better of science and technology
【3】Which of the following might be the best title of the passage?
A. Technical Innovations: Effectiveness of Precautions.
B. Technical Innovations: Worries and Information
C. Science and Technology: Security Tips for Users
D. Science and Technology: A Double–edged Sword

26、阅读下面短文，根据所给情节进行续写，使之构成一个完整的故事。
The Box Cat
Chester was born in a box with four other kittens. He was in a smaller box marked "free kitten" when Sasha met him and took him home. And from that moment on, he loved boxes. Every day after he finished grooming（刷洗）, licking his paws and fur with his tongue, he would look around for a box to sleep in.
He slept in hat boxes, gift boxes and takeout food boxes. He slept in Sasha's sock drawer, if she left it open. One year Sasha got a beautiful dollhouse for her birthday, a dark green three-story house with lots of furniture. Sasha loved it. So did Chester. He liked to push the furniture out of all the rooms and sit in the bedroom on the second floor. Sasha had to redecorate the dollhouse every day, but she didn't mind as long as Chester was happy.
One day Sasha came home from school, and she couldn't find Chester. He wasn't in the dollhouse, or her sock drawer, even though she'd forgotten to close it.
"Mom, Dad!" Sasha wailed（大叫）. "Chester is gone!"
Sasha's mom looked in the attic. There were boxes and dust bunnies, and even a mouse that had escaped Chester's notice, but no Chester. Sasha's dad looked in the kitchen cabinets, but no Chester.
Suddenly ---
"I found him!" Sasha cried.
Chester was inside her mom's new glass vase, and he didn't look happy at all. Even his whiskers（须）looked sad. Sasha tipped the vase over gently and tried to pull him out, but Chester just yowled（惨叫）.
"We'll have to break the vase to get him out!" Sasha cried.
Now her mom didn't look happy. It was a beautiful vase, clear glass with blue and green swirls.
"No," said her dad. "If we break it, the glass shards（碎片）might hurt Chester. Maybe we can put butter on the inside of the vase and slide him out, like the time you got that ring stuck on your finger."
Paragraph 1: Sasha's mom buttered as much of the inside of the vase as she could reach.
Paragraph 2: Soon they were at the vet's（兽医）office with an annoyed, frightened and buttery cat in a vase.
