1 . Animals can adapt quickly to survive unfavorable environmental conditions. Evidence is mounting to show that plants can, too. A paper published in the journal Trends in Plant Science details how plants are rapidly adapting to the effects of climate change, and how they are passing down these adaptations to their offspring(后代).

Plants are facing more environmental stresses than ever. For example, climate change is making winters shorter in many locations, and plants are responding. “Many plants require a minimum period of cold in order to set up their environmental clock to define their flowering time,” says Martinelli, a plant geneticist at the University of Florence. “As cold seasons shorten, plants have adapted to require shorter periods of cold to delay flowering. These mechanisms allow plants to avoid flowering in periods when they have fewer opportunities to reproduce.”

Because plants don’t have neural(神经的) networks, their memory is based entirely on cellular(细胞的),molecular(分子的),and biochemical networks. These networks make up what the researchers call somatic memory(体细胞记忆). “It allows plants to recognize the occurrence of a previous environmental condition and to react accordingly,” says Martinelli.

These somatic memories can then be passed to the plants’ offspring via epigenetics(表现遗传). “Several examples demonstrate the existence of molecular mechanisms modulating plant memory to environmental stresses and affecting the adaptation of offspring to these stresses,” says Martinelli.

Going forward, Martinelli hopes to understand even more about the genes that are being passed down. “We are particularly interested in decoding the epigenetic alphabet without changes in DNA sequence(序列),”he says. “This is especially important when we consider the rapid climate change, we observe today that every living organism, including plants, needs to quickly adapt to survive.”

2 . It is that time of the year, when a handful of world’s leading scholars, social activists and researchers are rewarded with what is often cited as the most prestigious acknowledgement of human effort-the Nobel Prize. Here’s a look at who has won the prize and for what.

Physiology or Medicine

Swedish geneticist Svante Peabo won the first Nobel of the year, for starting the field of ancient DNA studies. He is well-known for extracting, sequencing, and analyzing ancient DNA from Neanderthal bones.

Physics

Alain Aspect, John F. Clauser and Anton Zeilinger’s work in quantum (量子) technology landed them the second Nobel Prize announced in 2022. Although Aspect is from France, Clauser from the U.S, and Zeilinger from Austria, the three separately performed “groundbreaking experiments” as one team. “Their results have cleared the way for new technology,” the committee stated.

Chemistry

The Nobel Prize for chemistry went to another trio, Carolyn R. Bertozzi from the U.S., Morten Meldal from Denmark and K. Barry Sharpless from the U.S. “for the development of click chemistry and biorthogonal chemistry,” the committee stated. Dr. Bertozzi is the eighth woman chemist to be awarded the prize, while Dr. Sharpless is the fifth scientist to be awarded two Nobel Prizes.

Economics

The Prize in Economic Sciences was awarded to three American economists, Ben S. Bernanke, Douglas W. Diamond and Philip H. Dybvig “for research on banks and financial crises,” the Nobel Prize committee announced on Monday. By studying the history of American economics, particularly the Great Depression of the 1930s,they improved how we understand the role of banks during times of hardship and the bank’s impact on societal functions.

1. What prize is related to the research with bones?

A．Physiology.

B．Chemistry.

D．Economics.

2. For what study did Ben S. Bernanke, Douglas W. Diamond and Philip H. Dybvig win the prize?

A．About societal functions.	B．About the history of America.
C．About banks and financial crises.	D．About the Great Depression of the 1930s.

3. What do the prizes for physics, chemistry and economics have in common?

A．Their winners are from different countries.	B．They have three winners.
C．They improve new technology.	D．They help people understand hardship.

3 . The Feynman Technique(费曼学习法)is a powerful method that you can use to learn anything faster because it forces you to actively think about the problem instead of passively reading or listening to someone else talk about it. You can take the following five simple steps to study better.

·Find out the topic you want to learn.     1     Otherwise, you'll end up jumping between topics without developing a deeper understanding of any of them.

·Explain the topic as if teaching a sixth-grader. This step is the heart of the FeynmanTechnique—    2    .This requires you to meet the child at their level of understanding by using the simplest way.

.Identify areas of improvement in your explanation. You’ll need to critically(批判性地)review the explanation you cane up with in Step Two     3    . Try to find any knowledge gaps, together with any areas where you felt that you couldn't explain the topic simply.

·Improve and optimiez(优化) your explanation. Think about all the knowledge gaps and other areas of improvement you found before.     4    

· Repeat the steps until you’ve achieved mastery of the topic. Keep going through each step you're fully satisfied with your explanation.    5    , and that is why going through all the prior steps just once is usually not enough to achieve topic mastery.

A．Use those to improve your explanation

B．To do so, take a critical look at your explanation

C．Make sure that your explanation is interest-based

D．Your explanations need to be short and to the point

E．The Feynman Technique works best with a repeat

F．It’s important that you clearly know the topics you’re trying to learn

G．Explaining the topic simply enough to be understood by a sixth-grade student

4 . The United Kingdom is a land of natural beauty and history, with many of its finest attractions discovered through hiking. Now, dust off your boots, plan according to the following routes presented by a survey of senior hikers and an incredible experience will wait for you.

Wales Coastal Path

Wales is the only country in the world that has an official walking path covering its whole borders. The Wales Coastal Path is a footpath stretching 870 miles from Chester to Chepstow. Walking the whole thing might be demanding, but there are plenty of stretches that can be enjoyed over a day or two.

Southwest Coast Path

You need a fair amount of annual leave, a casual 52 days or so, to undertake this in one go. The route runs from Somerset all the way to Dorset, via rugged cliffs, cute fishing villages and surfing spots along the coastline. You can surely jump on to any point as you like, but you can't afford to miss all the pubs full of jokes and laughter on the way!

Coast to Coast Walk

This long-distance trail isn’t official, but popular in the country, taking hikers from the Irish Sea to the North Sea as it rolls into historic Robin Hood’s Bay in Yorkshire. Following local footpaths, the route takes you through three UK National Parks: the Lakes, the Yorkshire Dales and the North York Moors.

Cleveland Way

You’ll want nine days to folly complete this hike, which explores both the North York Moors and the county’s world-famous coastline. Just make sure you allow enough time to properly enjoy spots like Roseberry Topping hill and pick up a gentle afternoon walk at Whitby’s clifftop church.

1. Who will be more interested in the routes?

A．Explorers in the UK.	B．Hiking lovers.
C．Nature photographers.	D．Field researchers.

2. What is highly recommended about Southwest Coast Path?

A．Fishing villages.	B．Surfing spots.
C．Local pubs.	D．National parks.

3. What do the four routes have in common?

A．They include cliffs worth visiting.	B．They are official and demanding.
C．They run along the coast.	D．They can be completed in a month.

5 . The Music Educator Award, this year, went to Annie Ray, an orchestra(管弦乐队)director at Annandale High School.She was recognized for her efforts to make music accessible to all students, particularly those with disabilities.Ray got to attend the awards ceremony in Los Angeles and bring home a $10,000 prize.

Ray created the Crescendo Orchestra for students with severe intellectual and developmental disabilities, as well as a parent orchestra that teaches nearly 200 caregivers a year to play the same instrument as their child.Ray also works with a local charity to give damaged instruments a second life in her classroom.

The orchestra is about much more than just making music.The most important is to give students a chance to develop their cooperation skills, make mistakes and learn the art of refining something.Ray pushes her students to be brave, go outside their comfort zone and realize they have to learn how to make bad sounds before learning how to make good sounds.And they teach her a lot in return.” They changed my educational philosophy.I understand what it truly means to meet a student where they’re at and apply that elsewhere,” she said.

The warm reception on the ceremony was meaningful.Actually, not many people understand what exactly music educators do or how much their work matters.While her administration is supportive, that lack of understanding is a problem facing the profession in general.Another is resources.She says her school “desperately” needs new instruments.She will use some of her prize money to buy more.

Ray also plans to put some of the money towards an ongoing scholarship for students who want to pursue music when they graduate.She knows of several, those particularly interested in music, and aims to offer financial support needed to realize their musical dreams” It is hard but truly satisfying,” Ray said.“And there’s nothing else like it for them.”

1. What can we learn about Ray from the first two paragraphs?

A．She hosted the award ceremony.	B．She brought music to more people.
C．She gave away instruments to the poor.	D．She founded a local charity for children.

2. What do students benefit most from the orchestra?

A．They acquire in-depth musical knowledge.	B．They make friends with the like-minded.
C．They gain personal growth from playing music.	D．They improve their connections with educators.

3. What is paragraph 4 of the text mainly about?

A．The reception on the ceremony.	B．Importance of music education.
C．Challenges for music educators.	D．Plans to obtain resources.

4. What does Ray find satisfying according to the last paragraph?

A．Winning a scholarship.	B．Developing interest in music.
C．Making musical achievements.	D．Transforming dreams into reality.

I was eight years old and wasn’t aware of all the arrangements being made for our journey as a family to London in 1950. My mother was in great pain and wished to visit specialists in London. My father reluctantly had to sell our property in Queensland. The day before we boarded the ship, Father unwillingly said goodbye to his five-year-old cattle dog, Spider, who was loved by us all. Father’s friend Sandy was to be his guardian while we were overseas, as he had been getting to know Spider for many weeks.

Six weeks later, an airletter arrived from Sandy, giving my father the news that Spider had run away just two weeks after we had sailed. Sandy had advertised constantly on ABC and other regional newspapers. Despite many “sightings”, the dog was never found. It seems Spider just kept running and searching for us. As he was cattle dog, my father thought he would shoe or dingo-trapped, because of his appearance. But our family thought that Father held a secrets hope that Spider was still alive.

We sailed back to Australia two years later and re-established our home. My father immediately began his own search for Spider. One cold winter’s Saturday morning eight months after our return, my father had a call from an elderly lady living on her own on the outskirts of the town. As she told my father on the telephone, it was “just glimpses of a dingo-type dog in the shadows” of her disused tennis court. That was enough for my father to interrupt my homework.   

We set off in his blue and black Jensen car which he had brought back from England. It was hardly the right vehicle for the rough roads we travelled that day. Five and a half hours later, we found the run-down old property. Sadly, she told my father that the “dingo dog” hadn’t been around for a few days. My father had a strange look in his eye. He put two fingers to his lips and did his special whistle for Spider.

9 . 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。

Bacteriophages (phages) and other mobile genetic elements (MGEs) exert an immense selective pressure on     1    (bacterium), which in response have developed a broad arsenal of defence mechanisms.     2     these, CRISPR–Cas (clustered regularly interspaced short palindromic repeats–CRISPR-associated proteins) is a group of widespread RNA-guided adaptive immune systems that are classified into two broad classes, six types and numerous subtypes according to their genetic composition and interference mechanism1. The CRISPR–Cas immune response starts with the    3    (acquire) of short DNA fragments (protospacers) from invading MGEs. The protospacers are inserted as spacers between repeats in the CRISPR array to create a memory of the infection. Next, the CRISPR array is expressed    4     a long transcript that is processed into small, mature CRISPR RNAs (crRNAs), each    5    (carry) a spacer sequence flanked by part of the repeat. Finally, the interference complexes, composed     6     a crRNA and one (class 2) or more (class 1) Cas proteins, degrade the complementary nucleic-acid targets that are often found next to a short protospacer-adjacent motif (PAM). The specificity and programmability of the CRISPR–Cas machinery     7    (lead) to the development of various biotechnological applications in genome editing, molecular diagnostics and more.

In the evolutionary arms race with CRISPR–Cas, phages and other MGEs have evolved diverse strategies to block or circumvent immunity. One widespread evasion mechanism uses protein-    8    (base) CRISPR–Cas inhibitors called anti-CRISPRs (Acrs). So far, more than 100 Acr protein families have been identified    9     inhibit different stages of the CRISPR–Cas immune response, mainly by interacting directly with Cas proteins. For example, Acrs prevent crRNA loading, effector-complex formation, and target DNA binding and cleavage. Notably, the discovery of these natural ‘off switches’ has presented new opportunities    10    (control) the activity of CRISPR–Cas technologies.

A GIFT FOR GRANDPA

Summer vacation was coming. Jack and his brother Berlin were filled with excitement as they thought of visiting their grandparents again.

The big day came at last. After the happy family got ready, they set out for the grandparents’ eagerly. On the way, the brothers were excitedly talking about the fun they had with grandparents.

A little blue house with a tall white chimney finally appeared. Behind the property was the forest carrying their good memories with Grandpa. They arrived at the driveway, at the end of which Grandma was waiting for them joyfully.

Jack and Berlin each gave Grandma a big hug and then swept to the living room, shouting excitedly “Grandpa, we are back!”

Seeing his grandsons, Grandpa was wild with joy and tried to get up with all his strength from the chair but in vain. A helpless expression flashed on his face. Grandma explained that his health was declining rapidly and maybe couldn’t stand up on his own forever. But Grandpa declared stubbornly (倔强地), “I can!” Certainly, he was stuck in his boyish way. Mum and grandparents were happy to meet again after a long time. They sat together and chatted about what happened recently.

The brothers were soon bored with adult conversation, went out and wandered into the forest. Tall trees stretched up to the heavens with large branches crossing each other, while young ones rose straight like soldiers. Grandpa was once a great explorer full of wisdom. He could tell where the birds came from only by their calls and songs. The trees, birds, lizards, lots of bugs...How many merry moments they spent with Grandpa in the kingdom!

But now Grandpa couldn't get up. This made them worried. “We’d think out a way to cheer him up.” Jack said. “Grandpa is a bird lover, and we can catch him a bird.” Berlin suggested. “But he hates birds being caged!” Jack shook his head.

Then a bright idea came to Jack’s mind. “Why not make a cane (拐杖) out of a young tree!”
