1 . In comparison to many closely-related species, the human child takes a long time to grow up and requires a high degree of parental investment(亲情投资). Human children need more time to reach maturity(成熟)than other closely-related species.
A new study finds that one reason is the large amount of energy that the brain requires as it grows.
Christopher Kuzawa, first author of the study, explained: “Our findings suggest that our bodies can’t afford to grow faster during the toddler(幼童)and childhood years because a huge quantity of resources is required to fuel developing the human brain. As humans we have so much to learn, and that learning requires a complex and energy-hungry brain.”
Data from the study shows that at the moment when children’s bodies are growing the least-on average, at four years old-their brains are using the highest percentage of glucose(葡萄糖). That means that 40% of the child’s total energy expenditure is being used by its brain.
The findings support the theory that children take so long to mature because of the energy-intensive task of growing a massively over-sized brain in comparison to the brain-to-body weight ratio of other species.
Kuzawa continued: “After a certain age it becomes difficult to guess a toddler or young child’s age by their size. Instead you have to listen to their speech and watch their behavior. Our study suggests that this is no accident.”
Body growth nearly stops at the ages when brain development is happening at a lightning pace, because the brain is using up the available resources.”
“The mid-childhood peak in brain costs has to do with the fact that there are a huge number of synapses(神经元突触), connections in the brain, at this age, when we learn so many of the things we need to know to be successful humans.”

2 . Very far away from the city lived a poor farmer and his wife. In front of their house was a small dirt road. Very few cars drove on this road because it was so far from the city. On the dirt road, there was a big hole filled with water. The hole was very deep, but drivers on the road didn’t know just how deep. Drivers always drove into the hole, but they never drove out.
One day, a man in a new car was driving down the road. He saw the hole with the water, but he didn’t think it was very deep. He drove into the hole, but he couldn’t drive out. The man saw the farmer on his tractor working in the field, and he signaled to the farmer. The farmer drove over to the man in the new car.
“Is there a problem?” asked the farmer.
“Yes,” said the man. “My car is stuck in this hole. Can you help me?”
“Maybe,” said the farmer. “But I’m very busy.”
“If you help me, I’ll pay you,” said the man.
“OK,” said the farmer. The farmer pulled the car out of the hole with his tractor, and the man paid him a lot of money. The man looked at the farmer and said, “You must make a lot of money pulling cars out of this hole day and night.”
“Actually, no,” said the farmer.
“Why not?” asked the man.
“The hole is very deep, and a lot of people get stuck and ask for help. But I don’t make money day and night because I don’t pull cars out at night.”
“At night I’m busy filling the hole with water,” answered the farmer.

3 . Are you looking for some movies? You’ve landed on the right place. Let’s take a look at the list I’ve collected.
A Beautiful Mind
A Beautiful Mind is the story of John Nash, a mathematician who went on to win the Nobel Prize for his Game Theory. This movie brings his whole journey on screen—from his beginning to his downhill ride.
The first half is all about his rise to fame while the second half shows how he slowly falls into madness. After many years of fighting, he finally is victorious.
I.Q.
The story is about an auto mechanic who falls for Albert Einstein’s niece. The only problem is that she is engaged (已订婚的) to someone else. Fortunately, Einstein likes him. The young man pretends to be a physicist to run after her, but things don’t go as he has planned.
If A Beautiful Mind was a little too heavy for you, I.Q. would be the perfect fit. It’s a light drama that is funny and heartwarming for the most part.
Good Will Hunting
Good Will Hunting is a touching tale of a troubled young man called Will Hunting who is gifted with a natural talent in mathematics.
However, he is struggling to find his identity. He can solve any math problem, but not the one he seems to be struggling within his life. His life seems to be getting only worse until one day he meets Sean, a therapist, who helps him find direction in life.

5 . By now, we are all aware that social media has had a tremendous influence on our culture, in business, on the world-at-large. Social media websites revolutionized the way people communicate and socialize on the Web. However, aside from seeing your friend’s new baby on Facebook, or reading about Justin Bieber’s latest conflict with the law on Twitter, what are some of the real influences?
Social networks offer the opportunity for people to re-connect with their old friends and acquaintances, make new friends, share ideas and pictures, and many other activities. Users can keep pace with the latest global and local developments, and participate in campaigns and activities of their choices. Professionals use social media sites like LinkedIn to enhance their career and business development. Students can work together with their peers to improve their academic and communication skills.
Unfortunately, there are a few downsides too to social networking. If you are not careful, immoral people can target you for cyber bullying and disturbance on social sites. School children, young girls, and women can fall victim to online attacks which can create tension and suffering. If you are a victim of cyber bullying, do not take it lying down, but try to take appropriate legal action against the attacker.
Many companies have blocked social networks as addicted employees can distract themselves on such sites, instead of focusing on work. In fact, studies show that British companies have lost billions of dollars per year in productivity because of social media addiction among employees.
Also, what you carelessly post on the Internet can come back to trouble you. Revealing (泄露) personal information on social sites can make users vulnerable (易受伤害的) to crimes like identity theft, stalking, etc. Many companies perform a background check on the Internet before hiring an employee. If a potential employee has posted something embarrassing on social media, it can greatly affect their chances of getting the job. The same holds true for our relationships too, as our loved ones and friends may get to know if we post something undesirable on social networks.
Social media has its advantages and drawbacks as each coin has two sides. It is up to each user to use social sites wisely to enhance their professional and social life, and exercise caution to ensure they do not fall victim to online dangers.

7 . Traveling on an airplane can be a very tiring task even in the best of conditions, Sophie Murphy noticed an awful tension on a recent flight from Sydney to Melbourne. She first thought it was caused by typical bad-tempered passengers. But as the flight neared its end, it became obvious that something was very wrong.
A teenage boy with Down syndrome (唐氏综合症) who was traveling with his family had become upset and would not return to his seat, regardless of the cabin crew’s warnings over the loudspeaker that it was almost time to land. The pilot was forced to circle above the airport, delaying the landing—and angering people on the already tense flight.
As the boy’s elderly parents failed to persuade him to get off the floor and back into his seat, Murphy, who had been a teacher for more than 20 years, stood up and quickly headed to the back of the plane.
She found the boy in the passage between rows of seats, lying on his belly. She began chatting calmly with him, asking his name, his favorite book, and his favorite characters. He told her he felt sick and she tried to comfort him.
Minutes later, he allowed her to hold his hand—and then together they got properly back into airplane seats. Murphy asked for sick bags, and held them as the boy threw up several times. As she helped him clean up, she repeatedly told him everything would be okay and that they’d get through it together.
After the plane was finally able to land, no one was impatient to step off the flight as one might expect. Instead, calmed passengers—obviously following Murphy’s amazing example—allowed the boy and his family to depart first, smiling at them as they passed. His parents tearfully thanked Murphy for what she had done, and a doctor sitting nearby also let her know he had even taken notes on her expert way of handling the situation.

8 . Benefits of Sports
Doing sports is a physical, mental and social adventure. It’s a great way for children to take a break from studies and release extra energy. It also helps them lead fuller and happier lives as regular sports have proven beneficial to overall well-being.
The physical benefits of doing sports are probably the most obvious. Regardless of your fitness level when you start playing sports, you’ll notice an increase in your overall fitness once you’re involved.
Children who participate in sports might also benefit from the social aspect, feeling part of a group, building up responsibility and leadership.
Discipline is another social advantage. Most organized sports require a strict training and practice schedule. As a student-athlete, you need to balance studies and athletics.
There is no shortage of reasons to find a sport to get involved in. Are you ready to go? Pick one and get moving!
A.It’s not just your body that benefits from sports. |
B.Therefore, playing sports is going to make you more fit. |
C.But remember, a child’s self-worth should not be distinguished by victory or loss. |
D.If you play group sports, you’ll be part of a team that takes direction from a coach. |
E.Nearly every sport requires physical activities and the competitive skills. |
F.Among these, learning how to function as part of a team is the most important advantage. |
G.Only with strict discipline can you be successful both in the classroom and in the sports field. |
9 . Bertie knew there was something in the wind. His mother had been sad in recent days, not sick, just strangely sad. The lion had just lain down beside him, his head warm on Bertie’s feet, when Father cleared his throat and began, “You’ll soon be eight, Bertie. A boy needs a proper education. We’ve found the right place for you, a school near Salisbury in England.”
His heart filled with a terrible fear, all Bertie could think of was his white lion. “But the lion,” he cried, “What about the lion?”
“I’m afraid there’s something else I have to tell you,” his father said. Looking across at Bertie’s mother, he took a deep breath. Then he told Bertie he had met a circus owner from France, who was over in Africa looking for lions to buy. He would come to their farm in a few days.
“No! You can’t send him to a circus!” said Bertie. “He’ll be shut up behind bars. I promised him he never would be. And they will come to see him and laugh at him. He’d rather die. Any animal would!” But as he looked across the table at them, he knew their minds were quite made up.
Bertie felt completely betrayed. He waited until he heard his father’s deep breathing next door. With his white lion at his heels, he crept downstairs in his pyjamas, took down his father’s rifle from the rack and stepped out into the night. He ran and ran till his legs could run no more. As the sun came up over the grassland, he climbed to the top of a hill and sat down, his arms round the lion’s neck. The time had come. “Be wild now,” he whispered. “You’ve got to be wild. Don’t ever come home. All my life I’ll think of you, I promise I will.” He buried his head in the lion’s neck. Then, Bertie clambered down off the hill and walked away.
When he looked back, the lion was still sitting there watching him; but then he stood up, yawned, stretched, and sprang down after him. Bertie shouted at him, but he kept coming. He threw sticks. He threw stones. Nothing worked.
There was only one thing left to do. Tears filling his eyes and his mouth, he lifted the rifle to his shoulder and fired over the lion’s head.

10 . My teacher held up a piece of broken glass and asked, “Who broke this window?”
Thirty boys tried to think about not only what they had done, but also what the teacher might have found out. She seldom became angry, but she was this time.
“Oh,” I thought. I was the one who broke the window. It was caused by a naughty throw of a baseball. If I admitted guilt, I would be in a lot of trouble. How would I be able to pay for a big window like that? I didn’t even get an allowance. “My father is going to have a fit as a result of it,” I thought. I didn’t want to raise my hand, but some force much stronger than I was pulled it skyward (朝向天空). I told the truth, “I did it.” It was hard enough to say what I had done.
My teacher took down a book from one of our library shelves and I had never known my teacher to strike a student, but I feared she was going to start with me.
“I know how much you like birds,” she said as she stood looking down at my guilt-ridden face. “Here is the field guide about birds that you are constantly checking out. It is yours now. It’s time we got a new one for the school anyway. You will not be punished, but remember that I am not rewarding you for your misdeed (恶行), but I am rewarding you for your truthfulness.”
I couldn’t believe it! I wasn’t being punished and I was getting my own bird field guide — the very one that I had been saving up money to buy.
The lesson my teacher taught me stays with me every day, and it will echo forever.
