4 . 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。续写的词数应为 150 左右。

Anxiously and hurriedly, two young firemen，Adam and Ben arrived at the apartment of a single mother with two children after they answered a 911 call. To their surprise, they discovered that there was no emergency at all, only to find that the younger child, about three years old, was playing with the phone. Adam told the mother that she should let the kids play their own toys instead of the telephone. The mother said sorry to them, promising that she would make the kid far away from the telephone. The similar things would happen many times a year. All the firemen were not angry about it, especially with a three-year old kid. Adam and Ben looked around their house again and made sure there was really not any danger before they left their house. After they go on their fire engine (消防 车), Adam asked curiously, “Have you noticed something strange in their house?” Ben thought for a while and answered, “All of them weren't smiling. It seemed like they weren’t happy at all.” “Yes, you are right! But anything else? I still felt there was something wrong in their house." The two young men looked at each other, and cried almost at the same time, “There was no Christmas tree!”

It was December 23rd. It was a day when all families were preparing their Christmas buying gifts, making the delicious food, decorating their Christmas trees and so on, busy but happy. But the family they just met didn't have a Christmas tree in their house! It was pretty obvious that the family was having a poor life and they couldn't afford to buy a single Christmas tree! “Maybe they weren't going to have a Christmas this year. It was terrible!” Ben murmured (低声说) to himself.

5 . A dying battery is a huge annoyance for cell phone users. But for engineers? It’s an inspiration. “Can we design a smartphone which can make a phone call and have a conversation without the need for any kind of battery?”

Shyam Gollakota is a computer scientist at the University of Washington. He and his team have indeed designed a battery-free phone. It looks like a circuit board（电路板）, with touch-responsive number buttons. And it runs on just a few microwatts of power, which it harvests from light, and from the radio signals coming from a nearby wireless base station.

The team achieved the battery-free, energy-efficient design by abandoning two of power-hungry features of modern cell phones. One, it skips digital-to-analog conversion（数模转换）. And two, it does not produce its own wireless signals to make calls. Instead, when receiving signals, it absorbs incoming radio waves from the base station, and changes them directly into vibrations（震动）of its speaker. When sending signals, it uses the vibrations of its onboard microphone to change the way radio waves are reflected back to the base station. And it works.

This piece of equipment does have limitations：It can be only 50-foot away from the base station. The voice quality is pretty low. And you can’t check Facebook either. “Yet, we’re going to get there. This is again a first step. Think of it as like：you need to make a first move to basically get someplace where you can harvest power to do other operations,” said Shyam.“Andit’s those other operations that will be extremely important. Because, battery or not, you could argue that voice calls are by now just a completely basic feature of our smartphones.”

6 . Working from home has been a long-held dream for many employees craving more flexible work arrangements and comfort. With the fantasy coming true because of the outbreak of COVID-19, however, quite a few people find it less romantic than expected. Amid the ongoing epidemic, a large number of Chinese companies have ordered employees to work from home, looking to control the spread of the virus as staff members return from the Spring Festival travel rush.

Allowing employees to work from home-even if they are not symptomatic-and enabling virtual meetings could help limit the spread of the virus and assuage employees’ fears about exposure.

But there’s another side to the coin. As millions of people started to work at home, people found video communication difficult. Many telecommuting platforms, including DingTalk, an all-in-one mobile workplace from Alibaba, went through temporary outages due to surging demand.

Fu Yangang, a product manager at a house trading company in Beijing, found he couldn’t receive any messages from colleagues during an online meeting at home on Tuesday, and neither could they. Similar problems arose when they switched to Zoom, a California-based video communication app which provides remote conferencing services.

Residences filled with distractions such as spouses, parents, kids or pets set up another obstacle for many employees working from home. Xia Baigi, who works for an Internet company in Beijing, was required to stay at home in Jilin Province until Feb.10, but has found what was an oft-wished for working style a hindrance to productivity. Her parents, who don’t have much to do, suddenly became concerned about her job and asked many questions. “I love my mom and dad, but their current behavior just adds stress and strain,” she said. “Sometimes I have to lock myself in my own room to avoid their enthusiasm.”

For people who are able to stay as productive as they would in an office environment, they came across a different problem： “surprisingly” longer working time at home. Working for an investment company in Shanghai, Zhang Fei felt he could never escape from his job working at home in Shandong Province, which makes time management a whole lot messier. “There is no longer a’ work’ and’ no work’ time. My work comes calling at all hours, which can keep me at a frenetic pace,” he said. With the return date drawing closer, he said, he never felt so excited about being back at the office.

1. Why many people can work from home in China?

A．Because many employees think it is a fantasy idea.

B．Because the employers think more highly of working from home than traditional working.

C．Because the COVID-19 occurred.

D．Because large number of Chinese companies want to avoid the Spring Festival travel rush.

2. What’s the meaning of the underlined word in Paragraph 2?

A．Increase.

B．Ease.

C．Give up.

D．Find.

3. Which of the following statement is right?

A．After Fu Yangang and his partners switched to Zoom, their problem was solved.

B．Xia Baiqi’s parents could give her more constructive advice.

C．Xia Baiqi locked herself in her own room to avoid distractions.

D．By saying “There is no longer a ‘work’ and ‘no work’ time.”, Zhang Fei meant he can work less time when at home.

4. What is the best title for the text?

A．Working from home has unexpected challenges

B．Working from home can save you a lot of trouble

C．How to avoid distractions when working from home

D．More flexible, less work time

7 . Music influences your emotions. In turn, your emotions influence your behavior. One of these is your food intake.     1     What does science say about this subject?

Researchers at the University of Arkansas studied how music influences people when they eat in a restaurant. For the study, they used four types of music: jazz, classical, rock, and hip-hop. Their results showed that people had more appetite when they listened to jazz music while they ate.     2     This has a lot to do with emotions. For instance, when you listen to music with harmonic rhythms like jazz, you feel happier. This increases your appetite.

However, another study published in Psychological Reports suggests it isn’t only increased appetite that causes people to eat more.     3     A more stimuli-filled environment makes you eat more. In fact, they tend to urge you on to eat and even “encourage” you to eat faster. On the other hand, if the atmosphere in the restaurant is relaxed, you’re likely to feel more relaxed and spend more time enjoying yourself. For this reason, you’ll tend to eat less.

Besides, the study conducted by the Journal of the Academy suggests that the volume of music can also have an effect on how you eat. More specifically, the study states that, with low-volume music, you eat better because you make healthier choices. On the other hand, the study claims that music at high volume increases stimulation and stress.     4    

For this reason, restaurants should consider the fact when thinking about the optimization of their products and services.     5     They equip themselves with the technology needed to provide memorable experiences through music, greatly strengthening their relationship with the customer.

A．Does music influence how you eat?

B．Being in a rush to eat also plays a part.

C．Does your emotion boost your appetite?

D．However, they had less appetite when listening to hip-hop.

E．In fact, many catering establishments have already taken action.

F．This could prove to be quite an interesting concept for restaurants.

G．This means you’re more likely to order comfort food or other unhealthy options.

9 . According to the US economist Robert Gordon, all the “impressive stuff” has been created; we have run out of the big, life-changing ideas needed to encourage rapid economic growth and engineers are now only just making slight changes. Inventions such as mobile phones, Gordon says, have had less impact than, for example, the invention of indoor plumbing (管道系统).

But this is a misunderstanding of how engineers work. There is no “Wow!” moment. The development of new technology happens little by little. You build upon the work of those before you, thinking about what could be done better and what could be improved. It’s an unending task. Michael Faraday invented the first electric motor. But Faraday’s breakthrough followed William Sturgeon’s invention of the electromagnet (电磁铁), and Alessandro Volta’s invention of the battery before that. Faraday would have expected future engineers to pick up the baton (接力棒) later down the line.

Reduced energy supplies, increasing populations and mass urbanization keep clever young engineers awake at night. Those, for example, who enter the yearly James Dyson Award invent things that solve these problems and more. The 2012 winner Dan Watson designed a clever system of escape rings for fishing boat nets that deals with the issue of overfishing — not an exciting topic, but his invention is exceptional. Human inventiveness remains unreduced in the face of new global challenges.

Our problem is patience. We expect new technology at a rate like never before. I can’t tell you the world’s next big invention. Last week brought news that we’ve invented a new way to deal with antibiotic-resistant bacteria. Next week may bring a major development in another field. The biggest thing holding invention back is our impatience. With enough time and support, bright young engineers will develop exciting new technology to solve the world’s trickiest problems. Many have already begun.
