1 . Cutlery (餐具) including chopsticks, knives, forks and spoons which delivers an electric shock to change the taste of food could help cut down salt in fast food. Scientists have developed a pair of chopsticks, which can make food taste saltier, sour or bitter without the need for extra seasoning (调味). They are also working on a spoon and fork that could make food taste spicier or sweeter. This “digital seasoning” technology could help food manufacturers and restaurants to reduce the amount of salt they put into food without relinquishing taste.

They work by delivering pulses of electricity to the tip of the tongue to stimulate the tastebuds(味蕾). Dr Nimesha Ranasinghe, an assistant professor who led the work on the electric cutlery, said, “This technology is aimed at creating a virtual taste sensation.”

Some Chinese takeaway food and ready meals were recently found to contain up to 11 times more salt than a bag of crisps — more than half of an adult’s daily allowance. Salt is known to be linked to serious health problems like heart disease and stroke.

But using a pair of electric chopsticks could help cut salt levels without influencing the taste, said Dr Ranasinghe. The technology, which Dr Ranasinghe initially developed while at the University of Singapore, works by installing two electrodes (电极) into each chopstick or the end of a spoon. These electrodes send a weak current through the tip of the tongue when they touch it to stimulate the taste buds.

By controlling the frequency and strength of the electric current, the researchers can stimulate either sourness, saltiness or bitterness. They say up to 80% of people experience changes in saltiness and sourness with the devices and 70% can sense changes in bitterness.

Dr Ranasinghe said he was also working on ways of imitating sweetness and spiciness by rapidly heating and cooling the tongue. It could lead to a spoon that allows desserts to taste sweet while having lower sugar levels or a fork that can give a curry extra heat without the need for extra chilies (辣椒). Dr Ranasinghe said: “We have some early findings of imitating sweetness, a mint-cool sensation and hot or spicy sensations.”

2 . A 4—DAY GORILLA SAFARI(游猎) IN UGANDA

Just £3,500 per person!

What makes this trip extraordinary?

 Short fly—in safari for those with limited time, cutting down travel time.

 Two days tracking gorillas in Bwindi Impenetrable Forest.

 Explore the exciting Batwa Trail.

DAY 1 ENTEBBE—BWINDI

You will catch a short flight to Bwindi at Entebbe International Airport. Upon arrival, you will be met by your expert guide, and then take a bus to the lovely Bwindi Lodge (approx. 45 mins). It is a chance to relax and admire the views over the forest.

Overnight: Bwindi Lodge

DAY 2 BWINDI IMPENETRABLE FOREST

Today’s activities may be among the most exciting and challenging of any safari! The gorillas we will track belong to one of only a few family groups. For up to five years, these groups have undergone an extremely delicate process that has gradually brought them to tolerate the presence of humans for a brief period every day. The gorillas are by no means tame, and are completely wild animals. However, experienced guides will accompany you on your tracking. The guides will use their knowledge to locate the group’s whereabouts.

Overnight: Bwindi Lodge

DAY 3 BWINDI IMPENETRABLE FOREST

Today you can spend a second day tracking gorillas. Ideally, try and spend as little time today behind the lens of your camera as possible, so you can fully appreciate this precious experience.

3 . 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。

In today’s competitive world, the emphasis in athletics is so often put on breaking records. A runner’s creed: “I will win; if I cannot win, I shall do my best.” Those inspirational words, and others like it, fuel the soul of the long distance runners. Competing not only with one another, they hope to achieve their own “personal best”.

For one teen Brandon Schutt, a student in Omaha Burke High School, had been looking forward to his final cross-country race before graduating from high school. He was determined to finish the race with a respectable enough time to qualify for the upcoming state meet. Like him, all other runners were accumulating strength for a take-off.

One runner, Blake Cerveny, whose record was the fastest, tried to beat his own best. After a fast start, he continued to push himself to the limit. If he could hold on to his lead, there was no doubt that he would win. However, with less than 400 meters to go, Cerveny’s legs cramped up(抽筋)and failed him. Resolve to finish，Cerveny rose up from the ground, and continued on his way,only to fall again.His legs had simply given out. Seconds later, he lay curled on the ground, frustrated and disappointed. Other runners surpassed Cerveny with-out stopping. His will to go on faded from his body gradually.

A few moments later, Brandon, running at a very aggressive speed, drew near Cerveny. He had actually been in the same position three weeks prior when he wasn’t able to complete a race. He felt awful about not finishing. He had trained so hard for this final race in high school, to hopefully qualify for the state meet. So this time, he had made up his mind to prove himself under no circumstances.

4 . A method to transform a commonly thrown-away plastic to a resin(树脂) used in 3D printing could allow for making better use of plastic waste. A team of Washington State University researchers developed a simple and efficient way to transform polylactic acid (PLA) (聚乳酸),a bio-based plastic used in products such as filament,plastic silverware and food packaging to a high-quality resin.

“We found a way to immediately turn this into something that’s stronger and better, and we hope that will provide people with the inspiration to upcycle this stuff instead of just throwing it away,” said Yu-Chung Chang, a postdoctoral researcher in the WSU School of Mechanical and Materials Engineering and a co-corresponding author on the work. “We made stronger materials just straight out of trash. We believe this could be a great opportunity.”

Although it’s bio-based, PLA, which is categorized as a number 7 plastic, can float in fresh or salt water for a year without degrading. It is also rarely recycled because like many plastics, when it’s melted down and re-formed, it doesn’t perform as well as the original version and becomes less valuable.

“It’s biodegradable and compostable, but once you look into it, it turns out that it can take up to 100 years for it to rot away in a landfill,” Chang said. “In reality, it still creates a lot of pollution. We want to make sure that when we do start producing PLA on the million-tons scale, we will know how to deal with it.”

While the researchers focused on PLA for the study, they hope to apply the work to poly-ethylene terephthalate(PET)(涤纶树脂), which is more common than PLA and has a similar chemical structure and presents a bigger waste problem. They have filed a temporary patent and are working to further improve the process. The researchers are also looking into other applications for the upcycling method.

1. What can the method help do according to paragraph 1?

A．Solve financial crisis.

B．Change waste into wealth.

C．Control plastic production.

D．Determine 3D printing skills.

2. What does Yu-Chung Chang think of the method?

A．Unrealistic.

B．Imaginable.

C．Promising.

D．Common.

3. Which of the following is a feature of number 7 plastics?

A．They are hard to break down.

B．They are easy to deal with.

C．They are invaluable to recycle.

D．They are difficult to sort out.

4. What is the text mainly about?

A．Applications of an upcycling method.

B．3D printing with newly found materials.

C．A new way to turn plastic into valuable products.

Spreading Kindness Around the World

“Mom, we want to write a book,” my five-year-old twins, Delilah and Nathenial, told me one day.

I looked at my kids curiously. “What do you mean?”

Are they joking? I thought. I don’t know the first thing about getting a book published. Still, I didn’t want to squash their creativity. “Okay…what do you want it to be about?”

“An envelope that travels all over the world spreading kindness,” Nathenial said, his eyes shining.

Over the next few months,my kids dreamed up more of the story. The main characters were a pair of twins just like them. I wrote down everything, making sure not to miss a detail. The kids even sketched scenes with colored pencils.

The theme of Delilah and Nathenial’s story was being kind to others, no matter how little you might have. I wondered if that was partly because I’d told them what my life had been like when I was their age.

I remember my father died when I was five. My mom, younger sister and I ended up on the streets,sleeping in parks and homeless hotels for more than a year. I found myself standing in any line I could to get donated food.

Despite—or maybe because of—our hardships, I tried to help others. I handed out snacks to people who were homeless, took in stray (走失的) animals and helped give out donations at a church where the woman in charge would send me home with food. After I gave birth to our twins, I not only taught them to be kind but also to make sure they knew that anything was possible.

I guess I did a pretty good job, because here the twins were, at age five, managed to write a book. After we self-published The Magical Envelope last Children’s Day, the kids decided to donate it to the kindergarten in our community.

8 . Self-concept is how we perceive our behaviors, abilities, and unique characteristics. For example, beliefs such as “I am a good friend” or “I am a kind person” are part of an overall self-concept.    1    It also affects how we feel about the person we think we are, including whether we are competent or if we have self-worth.

    2    Ideal self: The ideal self is the person you want to be. Self-image: It refers to how you see yourself at this moment in time. Self-esteem: How much you like, accept, and value yourself all contribute to your self-concept.

Self-concept develops, in part, through our interaction with others.    3    For instance, one study found that the more a teacher believes in a high-performing student's abilities, the higher that student’s self-concept will be.

The media plays a role in self–concept development as well—both mass media and social media.     4    And the more often these ideals are presented, the more they affect our self-identity and self-perception.

Self-concept can change. Our environment plays a role in this process. Places that hold a lot of meaning to us actively contribute to our future self-concept through both the way we relate these environments to ourselves and how society relates to them.    5    This is particularly true with regard to individuals in our lives who are in leadership roles. They can impact the collective self (the self in social groups) and the relational self (the self in relationships).

A．Self-concept can develop in a number of ways.

B．It helps people understand why they feel the way they do.

C．It is believed that self-concept is made up of three different parts.

D．Self-concept can also change based on the people with whom we interact.

E．Our self-concept is important because it affects our attitudes and behaviors.

F．When these media promote certain ideals, we're more likely to make them our own.

G．Our family members, close friends and even others can contribute to our self-concept.

9 . You just never know when a skill you learned decades ago might come in handy.

Rosa was spending the day with her family at Thetis Lake when she heard a man crying out for help. The lake has a sudden drop-off, and the man was desperately trying to keep himself, his wife, and their son afloat. Rosa handed off her 4–month–old daughter to her mother and dashed down the hill and into the water.

Without thinking, Rosa dove into the water and swam hard for the family. When she reached them, they were so panicked that they repeatedly pushed her under the water, but Rosa didn’t give up. She tried to remember her lifeguard training—which was a long time ago when she was a teenager. Rosa was aiming for the drop-off ledge (平台), hoping to get the adults to a spot where they could touch the bottom. Yet as she approached the drop-off, Rosa couldn’t summon the strength to haul them all up. That’s when she heard the bystanders calling out encouragement from the shore. They responded by forming a human chain to drag Rosa and the family to shore!

Once they were safely out of the water, the family expressed their gratitude to Rosa and the others while gasping for breath. Rosa was relieved that those long–ago lessons returned to her when she needed them most, especially because she was never formally taught how to rescue groups! The heroic mom has now made it her mission to improve the safety of Thetis Lake. She’s requested more signage about the water drop–off and is campaigning to get lifeguards at beaches in the region.

Rosa insists she was just at the right place at the right time and says anyone would have done what she did, but we know a hero when we see one! Thank goodness this tough mother was there when that family needed her.

1. Why did Rosa dash into the lake?

A．To swim with her mother.

B．To rescue a drowning family.

C．To show her bravery to her daughter.

D．To teach a stranger how to swim safely.

2. What lifted Rosa up when she approached the drop–off?

A．Several swimmers’ timely appearance.

B．Her mother’s suggestions of being calm.

C．A lifeguard’s immediate response to danger.

D．Some strangers’ encouragement from the shore.

3. What made Rosa relieved?

A．Her family was saved at last.

B．She learned how to save groups.

C．Her former training worked in time.

D．She was highly honored for her kindness.

4. Which of the following can be used to describe Rosa?

A．Sensitive and curious.	B．Cautious and patient.
C．Determined and flexible.	D．Courageous and modest.

10 . Best Films to Watch in 2022

Jurassic World: Dominion

It is the final film in the second trilogy (三部曲) of dinosaur-movies. It’s the first one that really deserves to be called “Jurassic World” rather than “Jurassic Park”. Yes, prehistoric dinosaurs appear in the wild this time, rather than being stuck in a theme park. What’s even more exciting is that the (human) stars from the first Jurassic film have reunited.

Release date: 10 June, internationally

Director: Colin Trevorrow

Official Competition

Cruz and Banderas have been two of Spanish cinema's most famous superstars for decades, and yet have rarely acted on screen together. Now, once again, that wrong has been corrected by Official Competition,a good movie-business satire (讽刺作品). Cruz plays a director who is adapting a Nobel Prize–winning novel. Banderas is a Hollywood action hero who is hired to star in it.

Release date: 1 June in France, 9 June in Singapore, 17 June in the US and 30 June in Germany

Brian and Charles

Not a typical science-fiction movie, Brian and Charles is a low-cost British comedy starring and co-written by David Earl, a regular in situation comedies. “Brian and Charles is this year’s sweetest film,” says Cory. “It’s like an Edgar Wright’s Mighty Boosh project thrown into a cotton-candy machine,but also one of the most surprising films about being a parent, even when your son is a 7 feet-tall robot who loves cabbages.”

Release date: 17 June in the US and Canada

Director: Jim Archer

Lightyear

After four Toy Story films, everyone's favorite space ranger action figure, Buzz Lightyear, gets to leave Woody and friends behind, and starts an adventure on his own. In fact, the latest Pixar cartoon isn’t about the toy.
