1 . Fat is an important part of all living things and most body fat in animals and people is white. White fat allows people to eat more than they need when food is enough. It stores those extra calories until food becomes short.     1    

Hibernation(冬眠) can help animals get through the cold winter. They feed themselves on much food in fall in preparation for a long and cold winter. Animals don’t eat when they are hibernating.     2     To spend an entire winter, these animals enter a state called torpor(不活泼), where they use the white fat more slowly than they usually do.

When in torpor, it seems that animals have been sleeping. But torpor goes much deeper than that. In fact, animals’ activities slow down in torpor.     3     An animal may take several breaths and then stop breathing for several minutes. Instead of wasting energy to keep warm, bodies in torpor can remain just above freezing.     4     Every week or two, they will wake up. They stay awake for a day or so before going back into torpor. The time is different in different species. What causes the wake-up or why it happens is unclear. However, all true hibernating animals go through this cycle.

In order to wake up during the hibernation, these animals have to warm their bodies.     5     This process burns up white fat. And not only on hibernating animals, the warming process has the same influence also on humans, Ballinger explains.

A．But hibernating animals don’t stay asleep all winter long.

B．If so, they will suffer from hunger during the winter.

C．Their heart may beat only a few times each minute.

D．Instead, they burn their white fat to keep their bodies running.

E．They might feel comfortable when they wake up after a long winter.

F．Then the body burns it for energy to stay alive until more food shows up.

G．That   means going from a temperature above freezing to their usual body temperature.

2 . In Billings, Montana, some healthcare experts are using 3D printers to make reusable plastic masks. What makes them special is that the masks are then fitted with pieces of surgical (外科的) masks which can be replaced when needed.

“The surgical masks are cut into smaller squares that can be filled into the plastic mask to serve as a filter (过滤器) ,”said Dusty Richardson, a surgeon at the Billings Clinic. “The filter can be used for a day and you can substitute it the next day, but I do wash it for the next use,” Richardson added. The plastic mask and filter can be cleaned with soap, bleach (a chemical that is used to make something become white) and other cleaning chemicals. Richardson believes healthcare workers can get six to ten uses out of a single surgical mask.

Richardson came up with a prototype (原型) of the mask and worked with surgeon Spencer Zaugg and Spencer’s son Colton to make the design become a reality. They’re all really into 3D printing and Colton has design experience and was able to adapt a pattern he found online.

“Spencer and Colton have four 3D printers,” Richardson said. “They have created at least 15 masks so far.” Public schools in Billings are closed because of COVID-19, but some teachers went back into their classrooms on Monday to start printing out masks on their schools’ 3D printer. It takes a few hours to print a single mask.

Richardson said the files and instructions are posted online so anyone can make the masks on their own 3D printer. “I got a text from someone who printed one out in Scotland and is even working on it overseas,” Richardson said.

They’ve already made one huge improvement to their design. A company called HiTech Filters heard about the project and said that they could mass-produce filters using hospital-grade high-efficiency material quickly without wasting precious surgical masks.

“We’re just trying to help people here,” Richardson said. “We want healthcare providers and patients to be safe.”

5 . How to Beat the Rising Prices

A recent study by the Office of National Statistics tracked prices of essentials over a year. Pasta increased by almost 50%, bread by 16%and rice by 15%. So how do you combat the creeping cost of your groceries?     1    

Plan what you need to buy

    2     . First up, meal planning is a great way to ensure you have enough food in for the whole household, check what you already have so you can use these up with similar recipes but cost less. Then your plan can turn into a shopping list.

    3    

We’ve all got our favorite brands and supermarkets, and it can be hard to ditch these for cheaper alternatives. But doing this can make a huge difference. Look for own brand items. Which are often made similar recipes but cost less. It might be that you end up just swapping one or two items-but that’s still saving you some cash.

Take advantage of deals

Special offers can be a huge help, but you do have to be careful. Many. such as Buy-One-Get-One-Free(BOGOF). are designed to make us buy more than we need. But if you are certain you’re going to use something, then buying in large amounts when they’re on offer will bring savings.     4     from which I have benefited a lot.

Prevent food waste

Finally, you’ll save a decent chunk of cash by avoiding throwing out food. There are two parts to this. On one hand, there’s forgetting you’ve got something and it’s gone off before you can use it-so keep an eye on the dates.     5    As long as items have been properly stored they’ll be fine to consume after the date. So don’t throw away those packs of crisps, tinned tomatoes or cans of beer just because they’ve been out of date.

A．Change what you buy

B．Remember your freezer

C．You need to check a discount really is a discount too

D．I tend to do this for toothpastes, tissue or any other products that I use everyday

E．Best-before, on the other hand, is just a guide to the quality of the product

F．Well. there are some simple tricks you can try that’ll reduce what you spend

G．There are a few advantages of thinking ahead before you get to the supermarket

6 . Rahul Aggarwal was in medical school when he got the surprising news that his mother-a fit woman in her 40s-had been diagnosed with type2 diabetes (糖尿病). “I always thought of diabetes as a disease of people at higher weights and with certain lifestyle practices.” he recalls, “but my mom was an Indian American woman with a healthy weight and good diet and exercise practices.”

Aggarwal, now a clinical fellow at Beth Israel Deaconess Medical Center in Boston began thinking about how diabetes seems to affect certain ethnic and racial groups. It quantified diabetes risk in minority groups to determine if current screening recommendations are correct and equal.

The current standard was released in 2021 by the U. S. Preventive Services Task Force (USPSTF), which issues evidence-based guidance on disease prevention. The recommendation is to test adults aged 35 to 70 for diabetes if they are overweight or obese, defined as having a body mass index (BMI)of 25 kg/m2 or more. Aggarwal and his cooperators looked at the lowest-risk individuals qualified to screen under that rubric(评价量规). The researchers were shocked to find that the rate was about double for Hispanics and even higher among Black and Asian Americans. They concluded that to detect diabetes equally across all these groups, you would need to test Asian Americans with a BMI of 20 and Black and Hispanic individuals with a BMI of just 18. 5-measures considered to be in the healthy range.

Ngo-Metzger, who was the USPSTFs scientific director from 2012 to 2019, notes that “most studies of diabetes were done in middle-aged white individuals,” She argues that they ‘should be revised. “The study found that you would miss so many Blacks, Hispanics and Asians when you use these guidelines. I think it’s a kind of harm.”

B．She was diagnosed with diabetes at an old age.

C．Her poor diet and overweight accounted for her disease.

D．Her disease probably had a connection with her race.

2. What’s Ngo-Metzger’s attitude towards the current screening standard?

B．Positive

C．Neutral

D．Indifferent

3. What is the text mainly about?

A．New findings about cure diabetes.

B．The causes of diabetes are complicated.

C．More and more people suffer from diabetes.

D．The current screening standards are not proper.

4. What might be talked about in the following passage?

7 . In a series of Instagram posts this week the actress Kate Beckinsale shows her growing friendship with a fox in her mother’s London garden, encouraging him on to her lap by handfeeding him bits of ham and naming him Peepo. It’s as if Beckinsale is auditioning (试演) for alive-action of Snow White, commanding a series of forest animals at her finger tips.

Beckinsale-like pretty much one woman on every urban UK street—is a “fox feeder”. This troubles me. Not because of the old horror stories about city foxes stealing babies from their beds, but because it means that I have to accept that I’m not very cool. Foxes, on the other hand, are unbelievably cool. They were voiced in Wes Anderson’s stop-motion film Fantastic Mr Fox by the silver fox himself, George Clooney.

To be anti-fox is to be with Dahl’s boring rule-followers, Boggis, Bunce and Bean. To be pro-fox is to be with Ricky Gervais delightedly, filming Foxes partying in his Hampstead garden, or the DJ Annie Mac filming, this summer, a fox strolling into her kitchen from her London patio. The fox takes a cold glance at Mac sitting on the sofa, ignores her, then cuts her shoe before loping off out the door. It was a mint green Nike Air Force 1, retailing at about 100 a pair.

The London Wildlife Trust estimates that there are 10, 000 foxes in the capital and about half of them sleep in our garden. They have wandered into the house and learnt how to open the lock on our food waste bin by rolling it over and over down the street at 2 am until the lid swings open.

A few days ago I was at my front door late at night finding my key awkwardly when a fox walked behind me. Even though her dinner plans-the food-waste picnic hamper were right there, she seemed more interested in going to the house party without being invited. Only after I’d banged the door in her face did I feel safe. Do you still think it kind and safe to feed foxes?

1. What is the purpose of Kate’s feeding the fox in paragraph 1?

A．To attract her fans on Instagram.	B．To promote the live-action of Snow White.
C．To show that Kate is an animal lover.	D．To introduce the topic of the passage.

2. Who shares the same attitude with the author towards foxes?

A．Boggis	B．Annie Mac
C．Wes Anderson	D．Kate Beckinsale

3. What can we learn from the text?

A．Old horror stories make the author dislike foxes.

B．Wes Anderson starred in the film Fantastic Mr Fox.

C．George Clooney is a voice actor in Fantastic Mr Fox.

D．More and more people realize the danger of feeding foxes in the city.

4. What message does the author want to convey in the passage?

A．Foxes are pretty cool animals.

B．Foxes should be driven out of the city.

C．Feeding foxes in the city might not a proper action.

D．Foxes and human beings are living in harmony in the city.

8 . I’m Gu Ailing Eilleen, a professional freeskier, and twin-tipped skis, 22-foot halfpipes (U型滑道) and double-cork rotations are my main sources of adrenaline (肾上腺素), the truly addictive core of extreme sports.

Though it’s easy to label extreme sport athletes as fearless, the countless hours I’ve spent visualizing tricks and practicing them in foam pits and on airbags suggest otherwise. Instead of ignoring fear, we build unique relationships with it.

The work begins with visualization. I take a deep breath and close my eyes. As I go up the huge takeoff slope, I imagine extending my legs to maximize lift. Then I picture twisting my upper body in the opposite direction I intend to spin, generating force before I allow it to move back the other way.

1440 degrees. I smile. Then I open my eyes.

It doesn’t take much, unfortunately, for uncertainty to override confidence. Imperfect preparation moistens my palms and makes each breath shallower than the last. The feeling isn’t panic, but something like dread. Danger! cries every evolutionary instinct. Every freeskier’s goal is to recognize the minute differences between excitement and uncertainty in order to maximize performance while minimizing the risk of injury.

Finally, there’s pressure, an energy source that can be employed in many ways. I’m proud of the work I’ve done to cope with pressure by improving my self-esteem and minimizing my need for external validation. No matter how much time passes, I’ll always be a hopeless romantic when it comes to fear.

1. According to Gu, what mainly makes athletes fall in love with extreme sports?

A．The honor she will obtain if they win a match.

B．The athletes social status will be improved after winning.

C．The money they will be rewarded in the case of winning.

D．The athletes experience the feeling of excitement during the sport.

2. Why do athletes become fearless in extreme sports?

A．They are born fearless.	B．They overcome fear by practice.
C．They are forced to be fearless.	D．They just ignore fear.

3. What does “moisten” underlined in paragraph 5 refer to?

A．break

B．improve

C．unfold

D．wet

4. Which is the most suitable title for the text?

A．Gu Ailing is on the way to success.	B．I admit it, I am in love with fear.
C．How Gu Ailing overcomes her fear.	D．All success comes from hard work.
