Referred to as my hero, Jack, my brother, held significance in my life. Since he did everything before me, he always guided me and shared with his experiences I would have never had otherwise. As a master of learning and sports, he always accompanied me to study and take exercise. And he even got me through difficulties in life.

My first steps into high school were exciting but nervous, and I believed my extracurricular grades would be seen and valued by colleges. However, this sudden shift was difficult for me. Luckily, my brother noticed it all.

During that time, Jack was beginning his senior year and was finished with all the stressful subjects from junior year while I was studying for my very first math exam. Rather than just break into my room and sit down next to me, he let me decide by myself. He didn’t want to bother me because having someone sit next to me and micromanage my every move made me feel uncomfortable, leading to more stress and a feeling of distrust. Knowing this, he would leave me chips and snacks by my door, so I could pick them up whenever I felt like taking a break. He was there to help whenever I needed. With his encouragement and company, I became more confident while doing my homework.

The workload was just a major struggle for me during high school. Homework from advanced classes began piling up, and I was often stressed about different projects and deadlines. Moreover, there was also a math competition that my parents valued a lot, which needed plenty of practice every single day.

Even though I liked the time my brother gave me to figure out things on my own, it was reassuring to always have somebody who was willing to help me when I was stuck on an unsolvable problem. He would help me memorize formulas, explain different terms to me, and point out traps in different questions. And with his reputation as the best math student in our school, he could make those topics and questions simple to understand.

I began to spend hours at my desk focusing on getting a good score in the math competition.

6 . Virtually, there is nothing that man cannot do. Only what he has to do is keep doing and doing without being discouraged. Success will come someday or other, though it may apparently be the conception about something that it cannot be done.     1     But the reality is that man’s success depends on whether he can do the toughest tasks successfully. It is because our life is complicated and tough. And to succeed in this tough battle, perseverance and hard work are a must     2    . We can prove this fact when we look at the reality of life and the history of man’s success. Perseverance helps us do what we otherwise would consider impossible to do.

What the world-famous scientist Sir Isaac Newton had done by twelve years’ constant hard work was burnt out by his pet dog. But that could not discourage him a little.     3     It is only for his undefeated perseverance that’ we have been able to have many inventions and discoveries.

    4     He went through thick and thin to reach his destination after months of the strenuous voyage on the sea. He discovered the way from Spain to America and offered the world a new route of communication with America. This outcome of his perseverance will be generated by the world forever.

All the great men in history have written their names in golden letters by means of perseverance.     5     If we all are perseverant in whatever we do, we are sure to stand out as a successful nation in the near future.

A．Every action has its reaction.

B．It is a unique precondition to success in life.

C．In human life, perseverance plays a very important role.

D．Their success will always remain as perfect examples to us.

E．Columbus has left us an adventurous story of perseverance.

F．The task that is easily done at the first attempt is undoubtedly very easy.

G．He was able to do it again through years of hard work and perseverance.

7 . From the moment we are born, we interact with the world through movement. We move our lips to smile or to talk. We extend our hand to touch. How does our brain remember this wide range of motions? How does it learn new ones? How does it make the calculations necessary for us to grab a glass of water, without dropping it, squashing it, or missing it?

Technion Professor Jackie Schiller from the Ruth and Bruce Rappaport Faculty of Medicine and her team examined the brain at a single-neuron (单神经元) level to shed light on this mystery. They found that calculation happens not just in the interaction between neurons, but within each individual neuron. It turns out that each of these cells is not a simple switch, but a complicated calculating machine.

This discovery, published recently in the Science, promises changes not only to our understanding of how the brain works, but better understanding of conditions ranging from Parkinson’s disease to autism. And if that isn’t enough, these same findings are expected to advance machine learning, providing inspiration for new architectures.

“We used to think of each neuron as a sort of whistle, which either rings, or doesn’t,” Prof. Schiller explains. “Instead, we are looking at a piano. Its keys can be struck at the same time, or in order, producing an infinity (无限) of different tunes.” This complex music playing in our brains is what enables us to learn and perform an infinity of different, complex and precise movements.

These same findings can also serve as an inspiration for the machine learning community. Deep neural networks, as their name suggests, attempt to create software that learns and functions somewhat similarly to a human brain. Although their advances constantly make the news, these networks are primitive compared to a living brain. A better understanding of how our brain actually works can help in designing more complex neural networks, enabling them to perform more complex tasks.

8 . Some 20 percent of adults are procrastinators (拖延症患者). Everyone might put off a task or two, but long-term procrastinators do it at home, at school, at work and in their relationships.

For years, researchers have focused on the personalities of people who procrastinate. The results suggest procrastinators may be impulsive (冲动), worriers and have trouble regulating their emotions. But procrastinators are not lazy. They’re actually very busy doing other things than what they’re supposed to be doing. Though procrastinators may think they perform better under pressure, studies have reported the opposite. And when deadlines are uncertain, procrastinators tend to delay their work.

When people put off a tough task, they feel good-in the moment. Procrastinating is a way to avoid the negative emotions linked to the task. But the relief it provides is only temporary, and many seek out ways to stop procrastinating.

In fact, most research today suggests procrastination is a behavioral pattern, which means it’s something you can change, regardless of whether you’re impulsive. What works best is still under research. Some scientists have reported success with time management. But the evidence for that is all over the map. That’s because poor time management is a symptom not a cause of procrastination.

For some procrastinators, seemingly obvious tips can work. Researchers advise students to simply put down their smartphones. Silencing notifications or studying in the library rather than at home can regulate distractions and keep people on task. But that won’t be enough for many people. Stubborn procrastinators may benefit from cognitive behavioral therapy (认知行为疗法). This type of therapy, which involves managing thoughts and emotions and trying to change behavior, seemed to be the most helpful. Still, not many studies have examined treatments, and there’s room for improvement.

9 . A New Campaign to Stress the Benefits of a Balanced Diet

Look out for a new TV campaign, entitled “Eat Balanced”, which will highlight the continued benefits of eating meat and dairy (奶制的) products as part of a balanced diet.

Introduction

The campaign spearheaded by the Agriculture and Horticulture Development Board (AHDB) will appear on TV, social media and supermarket packaging and aims to highlight the nutritional benefits of enjoying red meat and dairy, while showing Britain’s world-class standards in food production and sustainability.

Basis

The campaign will be built on the following three key messages about meat and diary products:

●Meat and dairy products contain vitamin B12, an essential nutrient not naturally present in vegan diet;

●Red meat and dairy products from Britain are produced to world-class standards;

●Red meat and dairy products from Britain are among the most sustainable in the world.

The Aim

AHDB is conveying a message to consumers for a bright new year—enjoy the food you eat.

AHDB’s Chief Communications and Market Development Officer Christine Watts says, “In Britain, we have so much to be proud of when it comes to the food we eat, how it’s produced and the entire journey from farm to fork. Our farmers operate farms in the excellent way, so our food meets the international criterion. This campaign is aimed to balance the negative commentary around farming, as well as highlight the importance of eating meat and dairy products as part of a balanced and healthy diet.”

10 . 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。

Ever wonder    1    it would feel like to hide away in a dark cave without being connected to the outside world for 40 days? Fifteen people in France just did that. The group    2    (live) in a cave as part of the Deep Time project. The project was conducted by scientists from the Human Adaptation Institute, who wanted to see how they would react to and cope with being    3    (total) disconnected from the modern world. Since the volunteers    4    (cut) off from the outside world, they had to rely    5    their body clock to know when    6     (wake) up, go to sleep and eat. As expected, those in the cave lost their sense of time. “Time seemed to pass more slowly in the underground cave, where there were neither clocks    7    sunlight,” said Deep Time’s director Christian Clot.

The majority of the volunteers said they enjoyed the experience of total isolation. Two-thirds expressed a desire to remain underground a while    8    (long) in order to finish projects they had started. “The experience tested humans’ ability to adjust    9    (they) to the sudden huge changes in living conditions and environments,” said Clot. “We hope to better understand how our brains are capable of    10    (find) new solutions, whatever the situation.”
