Digital technology — email and smart phones especially — have vastly improved workers' ability to be productive outside of a traditional office. Even so, most white-collar work still happens in an office. One reason is that, according to findings of a new survey (调查) of office workers conducted by Wakefield Research for the IT company Citrix, most bosses are doubtful about remote working. Half of the workers say their boss doesn't accept it and only 35 percent say it’s tolerated.
Skeptical bosses will likely have their doubts reinforced (加深) by the same survey, which shows that 43 percent of workers say they’ve watched TV or a movie while “working” remotely, while 35 percent have done housework,and 28 percent have cooked dinner.
It is true, however,that working at home makes people much more efficient (高效的), because it allows workers to take care of annoying housework while still getting their jobs done. It’s much faster, for example, to shop for groceries at a quarter to three than to stand in line during the after-work rush.
The fact that such practices remain officially unaccepted reflects how far we haven't come as a society from the days when we expected every full-time worker to be supported by a full-time homemaker.
More broadly the Wakefield survey suggests that employers may be missing a low-cost way to give workers something of value. Sixty-four percent of those survey participants who have worked remotely would rather give up some bonus in order to get even one day a week working from home. Under such circumstances, smart firms need to find ways to let their employees have enough flexibility to manage their time efficiently.
1. Why do some employers hesitate to allow remote working?
A.They fear losing control of their workers.
B.They want to stick to their routine practice.
C.They have little trust in modem technology.
D.They are used to face-to-face communication.
2. What seems to be most workers’ attitude toward remote working?
A.Doubtful.B.Favorable.C.Reserved.D.Disapproving.
3. What does the author suggest smart firms do?
A.Shorten their office hours.
B.Give employees a pay raise.
C.Adopt flexible work patterns.
D.Reduce their staff’s workload.

文章大意:本文为议论文。我们生活中常会遇到交通拥挤的现象,蚁群中虽然蚂蚁很多,但是不会导致交通堵塞。本文用事实证明了蚁群可以避开交通堵塞。

【推荐1】Anyone who commutes (通勤) by car knows that traffic jams are an unavoidable part of life. But humans are not alone in facing potential backups.

Ants also commute —between their nest and sources of food. The survival of their colonies depends on doing this efficiently.

When humans commute, there’s a point at which cars become dense (稠密) enough to slow down the flow of traffic, causing jam. Motsch, a mathematician in Arizona State University, and his colleagues wanted to know if ants on the move could also get stuck. So they regulated traffic density by constructing bridges of various widths between a colony of Argentine ants and a source of food. Then they waited and watched. “The goal was to try to find out at what point they are going to have a traffic jam.” said Sebastien Motsch.

But it appears that that never happened. They always managed to avoid traffic jam. The flow of ants did increase at the beginning as ants started to fill the bridge and then levelled off at high densities. But it never slowed down or stopped, even when the bridge was nearly filled with ants.

The researchers then took a closer look at how the behavior of individual ants impacted traffic as a whole. And they found that when ants sense overcrowding, they adjust their speeds and avoid entering high-density areas, which prevents jams. These behaviors may be promoted by pheromones, chemicals that tell other ants where a trail is. The ants also manage to avoid colliding (碰撞) with each other at high densities, which could really slow them down. The study is in the journal eLife.

Can ants help us solve our own traffic problems? Not likely, says Motsch. That’s because when it comes to getting from point A to point B as fast as possible, human drivers put their own goals first. Individual ants have to be more cooperative in order to feed the colony. But the research could be useful in improving traffic flow for self-driving cars, which can be designed to be less like selfish humans— and more like ants.

1. What does the underlined word “this” in para.2 refer to?
A.Surviving.B.Avoiding jams.
C.Finding food.D.Commuting.
2. How did the researchers control the traffic density of the commuting ants?
A.By controlling the widths of their path.
B.By finding out the dense points.
C.By regulating their numbers.
D.By observing closely.
3. According to the research, ants can avoid traffic jams mainly because ________.
A.they follow a special route
B.they level off at high densities
C.they depend on their natural chemicals to adjust their speeds
D.they never stop or slow down on the way in the whole process
4. What is the best title of the passage?
A.Traffic JamsB.Unavoidable? Not for Ants!
C.Survival of an Ant ColonyD.Difference between Human and Ants

文章大意:本文为一篇说明文。文章主要介绍了气候危机导致的气温上升会缩短世界各地人们的睡眠时间。

【推荐2】Rising temperatures driven by the climate crisis are cutting the sleep of people across the world, the largest study to date has found.

The researchers used data from sleep-tracking wristbands (手环) used by 47,000 people over 7 months and across 68 countries. The analysis revealed that due to increasing night-time temperatures, the average global citizen is losing 44 hours of sleep a year.

However, lost sleep affects some groups much more than others. The sleep loss per degree of warming is about a quarter higher for women than men, twice as high for those over 65 years old and three times higher for those in less affluent nations, where people have less access to cooling features.

Previous studies have shown that rising temperatures damage health, including increasing heart attacks, mental health crises, and accidents and injuries. Poor sleep has also been shown to have these effects, and the researchers say their new study suggests that disturbed sleep may be a key mechanism by which heat causes these health impacts. The researchers say their data shows no signs of people being able to adapt to hotter nights.

“In this study, we provide the first planetary-scale (世界范围的) evidence that warmer than average temperatures cut human sleep,” said Kelton Minor, who led the research. “It’s very likely the effect is more serious.” Minor added that the research had important implications for policymakers, who need to ensure cities, towns and buildings are well adapted to heat in order to reduce the health impacts.

The data used in the study came mainly from richer nations. The wristbands also tended to be worn by people less prone (易于遭受) to sleep disturbance by warmer temperatures. “Lower-income people are underrepresented in the data and we’re well aware of that,” said Minor. He said more research was needed, particularly in places that are already among the hottest in the world.

1. Which is NOT mentioned about the study in paragraph 2?
A.How the data was collected.
B.How many respondents were involved.
C.The duration of the study.
D.The purpose of the study.
2. What does the underlined word “affluent” in paragraph 3 probably mean?
A.Thickly populated.B.Badly polluted.
C.Wealthy.D.Equal.
3. How do increasing temperatures harm people?
A.They cause car accidents.
B.They reduce people’s sleep time.
C.They result in extreme weather events.
D.They limit people’s adaptation ability.
4. What can be learned from Kelton Minor’s words in paragraph 5?
A.The study adopted a new research method.
B.Some cities have taken firmer action to fight the heat.
C.Policymakers have doubts about the study.
D.Heat’s impacts may be worse than estimated.
5. What does the last paragraph mainly tell us about the study?
A.Its findings.B.Its limitations.
C.Its applications.D.Its significance.

【推荐3】You can tell a lot about people's general state of mind based on their social media feeds. Are they always tweeting about their biggest annoyances or posting pictures of particularly cute kitties? In a similar fashion, researchers are turning to Twitter for clues about the overall happiness of entire geographic communities.

What they're finding is that regional variation in the use of common phrases produces predictions that don't always reflect the local state of well being. But removing from their analyses just three specific terms — good, love and LOL — greatly improves the accuracy of the methods.

“We're living in a crazy COVID-19 era. And now more than ever, we're using social media to adapt to a new normal and reach out to the friends and family that we can't meet face-to-face.” Kokil Jaidka studies computational linguistics at the National University of Singapore. “But our words aren't useful just to understand what we, as individuals, think and feel. They're also useful clues about the community we live in.”

One of the simpler methods that many scientists use to analyze the data involves correlating words with positive or negative emotions. But when those records are compared with phone surveys that assess regional well-being, Jaidka says, they don't paint an accurate picture of the local zeitgeist.

Being able to get an accurate read on the mood of the population is no laughing matter.

“That's particularly important now, in the time of COVID, where we're expecting a mental health crisis and we're already seeing in survey data the largest decrease in subjective well-being in 10 years at least, if not ever.”

To find out why, Jaidka and her team analyzed billions of tweets from around the United States. And they found that among the most frequently used terms on Twitter are LOL, love and good. And they actually throw the analysis off. Why the disconnect?

“Internet language is really a different beast than regular spoken language. We've adapted words from the English vocabulary to mean different things in different situations.” says Jaidka. “Take, for example, LOL. I've tweeted the word LOL to express irony, annoyance and sometimes just pure surprise. When the methods for measuring LOL as a marker of happiness were created in the 1990s, it still meant laughing out loud.”

"There are plenty of terms that are less misleading," says Jaidka. "Our models tell us that words like excited, fun, great, opportunity, interesting, fantastic and those are better words for measuring subjective well-being."

1. The researchers turn to social media feeds to________.
A.help with the analysis of people's subjective well-being
B.locate the most-frequently used words
C.prove the disconnect between language and emotions
D.make the prediction method more effective
2. How did Jaidka know the analysis wasn't accurate?
A.It didn't reflect the mood of the entire geographic community
B.It didn't match the assessment result of the phone surveys.
C.It didn't consider the features of Internet language.
D.It didn't take the regional variations into account.
3. Which of the following statements will Jaidka most probably agree with?
A.Face-to-face communication is needed to ensure happiness.
B.Internet use is to blame for the decrease in subjective well-being.
C.Internet language should be abandoned as a source of scientific analysis.
D.Less misleading words should be used in assessing subjective well-being.
