1 . Are you starting to feel a little burnt out by all the texts you’re getting? Constant conversations and messages make it harder to focus and could start stressing you out.     1     We’ll start with ways to choose and enforce your boundaries if someone tries to reach you when you’re not available.

Set daily times when you’re available.

Make a clear schedule each day for when you check your messages and are available to have a conversation.     2     It’s okay to read the texts you get during your leisure time, but don’t respond to them until you’re scheduled. Let anyone who would try to contact you know about your availability so they’re less likely to disturb you in the future.

Use screen time limits for your app usage.

Change your settings so you can’t use apps when you run out of time. Set a time limit for how long you can use your messaging apps. Sometimes you may run out of time.     3     Remember that it’s okay not to respond right away. If there is an urgent issue, someone can always call you.

    4    

Changing your boundaries can be tough, so keep strengthening them. Even though you may still get a lot of text messages, stick to the limits you set for yourself so you don’t stress yourself out or feel the need to reply. Otherwise, if you keep responding when you said you’re unavailable, other people might be confused or get mixed messages.

Silence the person if they don’t respect your boundaries.

Don’t hesitate to cut off communication if they still won’t listen. Some people may not understand your boundaries no matter how often you remind them. If you’re still bombed with messages throughout the day, silence the person or turn off notices from the app they use so you don’t get notified.     5    

A．Be consistent with your boundaries.

B．And it is impolite or rude.

C．You may not be able to access the apps until the next day.

D．Reply to the messages occasionally.

E．Give yourself set hours to relieve the pressure of replying right away.

F．Avoid responding to those people and their messages, and you can pull yourself out of a stressful situation.

G．Luckily, putting limits on how often you reply leaves you under less pressure.

2 . 阅读下面材料，在空白处填入1个适当的单词或括号内单词的正确形式。

Did you know chimpanzees(黑猩猩) have excellent mathematical and art skills? This was one of the ten studies     1    (award) at this year’s Pineapple Science Prize ceremony on March 13 in China. Over the past ten years, the Prize has explored the fun side of science and encouraged curiosity-driven scientific research.     2    , it’s not all funny business, in fact, all     3    (entry) must also be serious scientific studies. It is known that chimpanzees are much     4    (smart) than other animals, but we     5    (probable) don’t think they could heal university students or master art. A study by researchers from the Primate Research Institute of Kyoto University was     6     winner of this year’s award for mathematics and art.

    7    (use) their chimpanzee Abu and a control group of university students, the researchers surprisedly     8    (find) that Abu could remember random numbers both more quickly and more accurately than the students. In addition, the art skills of some chimpanzees demonstrate their ability     9    (connect) the real three-dimensional world     10     the two-dimensional world on paper, reflecting a huge jump in the brain.

3 . One of Switzerland’s most popular ski areas has been covering mountain areas with cloth material in an effort to reduce ice melt aver the summer.

Workers have ________ large blankets of material around Mount Titlis, a ski area near the Swiss mountain town of Engelberg. The area contains a glacier (冰川) that has been ________ large amounts of ice over the past 20 years. The ________ cloth, made of a chemical material, is designed to ________ the sun. “Putting the blankets ________ the glacier provides a natural protective shield,” Gian Darms, who oversees snow conditions and mountain security in the area, explained to Reuters. Decreasing snow cover ________ higher temperatures presents a huge ________ to ski areas across Europe. Having a glacier can provide some protection from ________ change. It can help ________ large snow supplies on the mountain year-round. This snow can later be moved to fill in areas where it is needed.

But the Swiss government has ________ that 90 percent of the country’s remaining 1,500 glaciers will ________ by the end of the century ________ nothing is done to cut man-made pollution emissions. Davms said he has had to ________ increase the size of the blankets over the glacier in recent years to save what is ________. A small group of ________ work over five-to-six weeks to cover parts of the glacier. ________ the summer, the workers spend weeks removing the ________.

Currently, the reflective material covers about 100,000 square meters, which is about the ________ of 14 football fields. The blankets help reflect the sun’s energy ________ into the atmosphere.

Collected ________ is used to fill openings in the glacier that could open up along the area’s ski runs. The snow also helps support lift structures that are fixed into the ice.

4 . Why is there a shortage of HGV drivers?

The UK needs 100,000 more HGV drivers if it is to meet demand, according to the Road Haulage Association (BHA).

Hod McKenzie, from the organisation, told Sky News it was a “critical situation” and a “cocktail of chaos” had led to the crisis.     1    ?

Retiring drivers

It says around 2,000 drivers are leaving the industry every week, often due to retirement, with only 1,000 new recruits joining over the same period. Mr McKenzie told Sky News, “    2    , so we’ve got more lorry drivers leaving the profession because they want to retire.”

Cost of training and pay

“We want younger people to want to be truckers, and it’s expensive—at least £4,000, possibly £7,000—to train to be a trucker and that’s beyond the pockets of most young people,” he told Sky News. “So we’ve got to make it easier to take that financial burden away from them and make it easier for them to gel in and stay in.     3    .”

Working conditions

    4    , according to Ms Short. She said, “When we’re trying to attract talent from mainland Europe to come here and work, and the pay and conditions that they have there are better, we need to consider how we can look at things like that for them as well.”

    5    

A change to rules on how people pay tax has been blamed for some HGV drivers leaving the industry. The reform of the IR 35 rules were designed to prevent workers from setting up limited companies through which they pay less tax and National Insurance while working, in effect, as an employee.

A．Tax changes

B．HGV driving tests

C．So what are the causes

D．What will be done to fix the problem

E．We’ve got an ageing population of lorry drivers

F．One of the problems we've had has been low pay and that’s now being addressed

G．Conditions at roadside services in the UK are “far worse” than in mainland Europe

5 . A NASA spacecraft that will deliberately crash into an asteroid (小行星) is preparing to launch this week. The DART mission, or the Double Asteroid Redirection Test, will lift off at 10:20 p. m. PT on November 23, 2021 aboard a Space X Falcon 9 rocket from Vandenberg Space Force Base in California. Live coverage of the event will air on NASA TV and the agency’s site. But the true test for this asteroid deflection (偏转) technology will come in September 2022, when the spacecraft reaches its destination, to see how it affects the motion of a near-Earth asteroid in space.

The mission target is Dimorphos, a small moon orbiting the near-Earth asteroid Didymos. This will be the agency’s first full-scale demonstration of this type of technology on behalf of planetary defense. It also will be the first time that humans have changed the motion of a solar system body in a measurable way, according to the European Space Agency.

It’s the perfect time for the DART mission to occur. Didymos and Dimorphos will be relatively close to Earth—within 11 million kilometers—in September 2022. The spacecraft will come speeding in at about 24,140 kilometers per hour, targeting Dimorphos, said Nancy Chabot, DART coordination leader at the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland.

The mission’s aim is to deliberately crash into Dimorphos to change the asteroid’s motion in space, according to NASA. This collision will be recorded by CubeSat, a companion cube satellite provided by the Italian Space Agency. It’s the Italian Space Agency’s first deep space mission.

The briefcase-size CubeSat will travel on DART and then be moved from it before impact (撞击) so it can record what happens. Three minutes after the impact, the CubeSat will fly by Dimorphos to capture images and video. The video of the impact will be streamed back to Earth, which should be “pretty exciting,” said Elena Adams, DART mission systems engineer at the Johns Hopkins Applied Physics Laboratory.

1. Which of the following is true according to the text?

A．The Italian Space Agency has launched deep space missions before.

B．The spacecraft will reach its destination in September 2022.

C．Humans changed the motion of a solar system body in the past.

D．Didymos and Dimorphos are 11 million kilometers away from Earth now.

2. Why will the spacecraft deliberately crash into an asteroid?

A．To destroy Dimorphos completely.	B．To be recorded by CubeSat.
C．To change the asteroid’s motion in space.	D．To show the technology.

3. What’s Elena Adams’ attitude to the coming video of the impact?

A．Positive.

B．Skeptical.

C．Cautious.

D．Unclear.

4. What does the passage mainly talk about?

A．NASA’s DART mission is set to launch.

B．A spacecraft will deliberately crash into the Moon.

C．NASA will show off its technology of defending the Earth.

D．A Space X Falcon 9 rocket will be launched this week.

6 . Many of us check labels to ensure the food we buy is healthy. But how many of us check what we eat, is produced in a way that benefits the environment? Some fanning methods actually help reduce carbon emissions, for instance by removing carbon from the atmosphere and improving the quality of the soil. Many smaller-scale farmers use these “regenerative farming” practices, but big food companies are also getting on board.

So what is “regenerative farming” and how can you tell if the food is produced in this way? Asking questions about the fanning methods used to produce food may not provide the precise answers you want (unless you talk to the farmers). But interest in and knowledge about regenerative farming are growing, and shops may he able to investigate and come back to you.

How has produce been grown?

Farmers using a regenerative approach typically avoid or minimize tilling (犁地) to protect the structure of the soil and its microorganisms. These microorganisms are vital for soil fertility and protect crops from pests and disease. Good soil structure also helps to prevent flooding and pollution. Regenerative farmers also typically plant a groundcover of herbs, wildflowers and grasses. These add nitrogen (氮) to the soil, encourage wildlife and pollinators, help prevent erosion and flooding, and control weeds.

Have pesticides (杀虫剂) and artificial fertilizers (肥料) been used?

Regenerative farmers may maximize crop diversity and rotate crops to reduce the need for chemical inputs and support wildlife, because artificial fertilizers are responsible for about one percent of all global, carbon dioxide.

How has the product been transported?

How it is transported is important, and food air miles can have 100 times the carbon footprint of miles of transportation by sea. If fruit and vegetables aren’t in season when you buy them, try to find the miles if they have been flown in or grown in a hothouse heated by fossil fuels. “If you can’t buy direct from a local producer, and obviously many people can’t, you need to do some research,” a farmer says, “Try to make your supply chain as short as possible.”

What have the animals been fed?

There are environmental benefits to being grass-fed, and feeding animals imported grains may be bad for the environment.

1. Which of the following is a regenerative farming method?

A．Minimizing the microorganisms.	B．Limiting crop diversity.
C．Growing herbs, wildflowers and grasses.	D．Slopping using fertilizers.

2. We can help reduce carbon emissions by ______.

A．picking up food from the nearby markets	B．feeding animals with imported grains
C．buying local products directly from farmers	D．transporting goods by air rather than by sea

3. What can we infer from the passage?

A．Big food companies are starting to use regenerative farming.

B．Fruit grown in the hothouse isn't available everywhere.

C．It is no use asking farmers about the farming methods.

D．People are clear about how food is produced.

4. What’s the purpose of this passage?

A．To instruct farmers how to farm regeneratively.

B．To encourage less use of pesticides and artificial fertilizers.

C．To promote local products to customers.

D．To teach customers how to tell regenerative farming.

7 . Doctors told us that our son, Matti, had a rare disease affecting his kidneys. We were in complete shock.

One of us would need to provide a kidney for him. This situation could have completely thrown us, but we decided to take it as it comes. We were in the hospital for a month and have to come back quite often.

Between the ages of 18 months, Matti was stable with the help of medication. Without warning, the function of Matti’s kidneys went downhill very quickly, before failing completely — what the doctors warned us of at birth.

Initially, we hoped dialysis would only be a couple of months until the kidney transplant happened, but the outbreak of COVID-19 mean I that it was put on hold.

As is known, it was tough trying to keep track of how much water he could take in. He was limited to 600 ml a day as required, but the restriction felt especially hard over the summer. In general, Matti was pretty accepting this — but there were moments when, understandably, he hated it. There were moments when we all got frustrated, I can’t deny.

Stefan and I had decided that he’d be the one to give Matti a kidney. Stefan was rejected, leaving me to be considered. I was nervous that the doctors would discover something that wouldn’t work with me too. But, thankfully, I was a match. I could barely explain the relief I fell when I woke up, to hear that the kidney had made it over to Matti safely.

Of course, there follow a lot of medications, and a specialist comes to bring a bit of fun to what can be a boring day. He is invaluable and occupies my son so that I can grab a coffee and a break. What I have learned is that nothing is more important that health.

1. What was the problem with the author’s son?

A．He had a rare disease at the age of 18 months.

B．He had a kidney transplant as soon as he was born.

C．His kidneys were damaged by an illness at birth.

D．He had to depend on dialysis to live all his life.

2. The underlined expression “put on hold” in Paragraph 4 probably means ______.

A．performed

B．cancelled

C．continued

D．delayed

3. What can we learn from the passage?

A．The author’s son was always ready to do what he was required.

B．Stefan failed to give his kidney because of his poor health.

C．The operation couldn’t have been successful without the specialist.

D．The couple had already been informed of his son’s condition before.

4. What kind of person is the specialist according to the text?

A．Helpful and considerate.	B．Clumsy and careless.
C．Modest and devoted.	D．Easy-going and cheerful.

For just 2 hours a week, there’s a simple practice that could make you healthier. Over the years, it’s becoming     1     (increasing) clear that spending time in nature is somehow linked to healthier and happier lives. But while some     2     (physician) have literally started “prescribing” (开药) doses of the natural world, like they will exercise, such practices are far from established.

Researchers in the United Kingdom have now taken     3     small but important step towards one of the most crucial, unanswered questions: How much time outdoors is enough? Drawing on a nationwide survey of nearly 20,000 British adults from 2014 to 2016, the team thinks they might have found a weekly “sweet spot” for nature exposure. “    4     (compare) to no nature contact last week, the likelihood of reporting good health became significantly greater with contact over 120 minutes,” the authors conclude. The findings are supported by past research, which has found that living in greener areas is associated with     5     (low) risks of cardiovascular disease (冠心病), obesity, diabetes, mental distress, etc.

    6    , these results are still in their early development, and it remains unclear how much exercise we humans truly need     7     (enjoy) the benefits. Participants in the last study     8     (ask) how much nature they had experienced in the last seven days. Randomly selecting just one of these “nature diary entries”:, the interviewer then asked for more details,     9     (include) how long the visit was, who they went with, and what they got up to. Bringing together these responses, the authors found that individuals who spent less than two hours in nature across the week reported health and well-being similar     10     those who experienced no nature.
