American farmers have been complaining of labor shortages for several years.The complaints are unlikely to stop without an overhaul(全面修订)of immigration rules for farm workers.

Congress has obstructed(阻挠)efforts to create a more straightforward visa for agricultural workers that would let foreign workers stay longer in the U.S.and change jobs within the industry.    1     .

Perhaps half of U.S. farm laborers are undocumented immigrants.As fewer such workers enter the country,the characteristics of the agricultural workforce are changing. Today's farm laborers.while still predominantly born in Mexico,are more likely to be settled rather than migrating and more likely to be married than single.They're also aging. At the start of this century,about one-third of crop workers were over the age of 35.Now more than half are.And picking crops is hard on older bodies.One oft-debated cure for this labor shortage remains as implausible as it's been all along:Native U.S.workers won't be returning to the farm.

Mechanization isn't the answer,either--not yet,at least. Production of corn,cotton,rice,soybeans,and wheat has been largely mechanized,but many high-value,labor-intensive crops,such as strawberries,need labor.    2     .

As a result,farms have grown increasingly reliant on temporary guest workers using the H-2A visa to fill the gaps in the workforce.Starting around 20l2,requests for the visas rose sharply;from 2011 to 2016 the number of visas issued more than doubled.

    3     . Even so,employers complain they aren't given all the workers they need.The process is cumbersome,expensive,and unreliable.One survey found that bureaucratic delays led H-2A workers to arrive on the job an average of 22 days late.The shortage is compounded by federal immigration raids,which remove some workers and drive others underground.

In a 2012 survey,71 percent of tree-fruit growers and almost 80 percent of raisin and berry growers said they were short of labor.Some western farmers have responded by moving operations to Mexico.    4     . Little more than a decade later,the share of imports was 25.8 percent.

In effect,the U.S.can import food or it can import the workers who pick it.

A.One trouble with U.S. agricultural workforce is the high mobility of crop workers.
B.The H-2A visa has no numerical cap,unlike the H-2B visa for nonagricultural work,which is limited to 66,000 a year.
C.Even dairy farms,where robots do a small share of milking have a long way to go before they're automated.
D.From1998 to 2000,14.5percent of the fruit Americans consumed was imported.
E.To attract younger laborers to the farm work is the much argued solution to the labor shortage in U.S.farming.
F.If this doesn't change,American businesses,communities,and consumers will be the losers.

【推荐1】Last week, Vodafone started a test of the UK’s first full 5G service, available for use by businesses in Salford. It is part of its plan to trial the technology in seven UK cities. But what can we expect from the next generation of mobile technology?

One thing we will see in the preparation for the test is lots of tricks with the new tech. Earlier this year, operators paid almost £1.4 billion for the 5G wavelengths, and to compensate for that cash, they will need to catch the eye of consumers. In September, Vodafone used its bit of the range to display the UK’s first hologram(全息) call. The Manchester City captain Steph Houghton appeared as a hologram in Newbury. It isn’t all holograms, however: 5G will offer faster Internet access, with Ofcom(英国通讯管理局) suggesting that video that takes a minute to download on 4G will be available in just a second.

The wider application is to support connected equipment on the “Internet of things” –not just the Internet-enabled fridge that can reorder your milk for you, but the network that will enable driverless cars and delivery drones(无人机) to communicate with each other.

Prof William Webb has warned that the technology could be a case of the emperor’s new clothes. Much of the speed increase, he claims, could have been achieved by putting more money in the 4G network, rather than a new technology. Other different voices have suggested that a focus on rolling out wider rural broadband access and addressing current network coverage would be more beneficial to the UK as a whole.

Obviously, 5G will also bring a cost to consumers. It requires a handset for both 5G and 4G, and the first 5G-enabled smart phones are expected in the coming year. With the slow pace of network rollout so far, it is likely that consumers will end up upgrading to a new 5G phone well before 5G becomes widely available in the next couple of years.

1. Why does Prof William Webb say “the technology could be a case of the emperor’s new clothes”?
A.He is in favor of the application of the new technology.
B.5G will bring a cost to comsumers in their daily life.
C.5G helps people communicate better with each other.
D.He prefers more money to be spent on 4G networks.
2. The underlined word “addressing” in the fourth paragraph has the closest meaning to ________.
A.making a speech toB.trying to solve
C.managing to decreaseD.responding to
3. The last paragraph indicates that ________.
A.it’ll take several years to make 5G accessible to the public in the UK
B.5G service shows huge development potential and a broad market
C.customers are eager to use 5G smart phones instead of 4G ones
D.it’s probable that 5G network rollout is speeding up in Britain
4. What do we know about the text?
A.Vodafone is successful in spreading the 5G service.
B.Steph Houghton appeared as a hologram by 4G.
C.The application of 5G will make life much easier.
D.5G phones are available in rural areas of the UK.
5. What’s Prof William’s attitude towards 5G service, the new generation of mobile technology?
A.Favorable.B.Negative.
C.Indifferent.D.Objective.

【推荐2】Do you jump out of bed early, wide awake and ready to start your day?If so, you would be called an “early bird”. Perhaps, you hate the sound of your alarm clock each morning and have little energy until afternoon. If so, you're probably a “night owl”.

Most people can be divided into such two groups, but what makes us this way?And is one better than the other?There are different opinions.

Usually, early risers have been praised as hard-working while those who prefer to get up late are considered lazy. Most people believe the early bird catches the worm.

Yet some scientists now believe “night owls” can really focus(集中) longer and produce more than early risers.

Research has found that the early bird does not always get the worm. In a Belgian study, both “morning people” and “evening people” were watched during their normal asleep and awake routines(常规).After 10 hours of being awake, the “evening people” became more alert(思维敏捷的). However, the “morning people” became sleepy and less focused. Researchers believe the reason for this difference is that night owls receive a last-minute increase from their brains. This added energy allows them to stay alert for longer periods of time.

Environment, lifestyle, activities and childhood routines all may have an effect on sleeping habits, yet genetics(遗传学)may play the biggest role.

It is possible to change your sleeping habits through regular bedtimes, early exercise and by avoiding midnight snacks. But if you're happy rising early or staying up late, you're probably doing what works best for your own personal body clock.

1. The author introduces the subject by ________.
A.telling an interesting story
B.giving different opinions
C.showing research results
D.asking a question

A.Those who get up early achieve their goals.
B.Early to bed, early to rise is good for health.
C.“Night owls” can focus longer than “early birds”.
D.“Early birds” are as hard-working as “night owls”.
3. What did the researchers find in a Belgian study?
A.Late risers become sleepier than early risers.
B.Early risers become as focused as later risers.
C.Late risers can think quickly after being awaken for 10 hours.
D.Early risers can think clearly after being awake for 10 hours.
4. What opinion does the author finally agree to?
A.People should get up early.
B.Whatever time suits you, it’s OK.
C.Staying up late is good for health.
D.It’s impossible to change one’s sleeping habit.

文章大意:本文是一篇说明文,主要讲述了一项新研究表明以安全的名义放弃同情可能对我们的心理健康有害。

【推荐3】A new study suggests that turning away from compassion (同情) in the name of safety may not protect us as we hope. Shutting off our compassionate response may threaten our mental health, the research team found. “This research shows the harmful effect of controlling our natural ability to connect with others,” says Leah Weiss, a founding member of Stanford University’s compassion cultivation training program.

To explore how attitudes toward compassion were affecting people’s well-being, University of Coimbra psychologist Marcela Matos and her team employed over 4000 people from 21 countries. All of the participants completed an online survey in spring 2022 that asked them to describe what they think of compassion, how their psychological state is and how strong their social connections are.

When the team analyzed the survey responses, they found that participants who expressed a fear of showing compassion for themselves or others were likely to feel more depressed, anxious, and stressed out. People with a fear of compassion also reported feeling less connected to others.

Marcela’s findings are consistent with earlier research showing the damaging effects of isolation and withdrawal on mental health. “Social isolation is associated with not just loneliness, anxiety, and depression, but also an increased risk of high blood pressure and cognitive decline,” says Australian psychologist Hugh Mackay, author of The Kindness Revolution.

On the other side, people who choose compassion during stressful situations seem to have a more durable sense of well-being. Training programs that promote people’s compassionate response appear to reduce their fear of compassion, based on results from another of Marcela’s studies.

Once people realize that compassion can benefit them in tough times as much as it benefits others, they’d be motivated to pull out of an isolation situation. “We have natural desire for social connection, community, kindness and compassion, because those are the pathways to social harmony and cooperation,” Mackay says. “If you can find the resources to address the needs of other people, your own anxieties tend to melt away.” Thus, it’s better to show sympathy.

1. What information were the participants required to provide?
A.The range of their social circle.B.The levels of their compassion.
C.Their beliefs about compassion.D.Their physical and mental states.
2. What did the team find about avoiding compassion?
A.It damages social connections.B.It can lead to physical disorders.
C.It reduces one’s life satisfaction.D.It threatens one’s ability to recover.
3. Why are earlier research and Marcela’s other studies mentioned?
A.To further support the new findings.
B.To provide background information.
C.To make comparisons between them.
D.To come up with different viewpoints.
4. What does the author intend to do in the last paragraph?
A.Compare notes.B.Make a promise.
C.Give an example.D.Provide advice.
