1 . Have you ever had the urge to open a book and stick your nose straight into the pages? The smell of old books can refresh any book lovers. We don’t know why, but it is just pleasant to us.
Describing the smell can be a challenge. And mere adjectives will likely be of little use to future generations of historians trying to document, understand or reproduce the scent of slowly decaying books. Now, that task may have just gotten easier thanks to the Historic Book Odor Wheel.
In one experiment, researchers asked visitors at the historic library to characterize the scents they smelled. All the visitors selected words like “woody”, “smoky” and “earthy” from the list, and described the smell’s intensity and perceived pleasantness. In another experiment, the study authors presented visitors to the Birmingham Museum with eight smells — one of which was an unlabeled historic book scent and seven were non-bookish, such as coffee, chocolate, fish market and dirty clothes. The researchers then had those museum goers describe the historic book smell.
The top two responses? Chocolate and coffee. “You tend to use familiar associations to describe smells when they are unlabeled,” study author Cecilia Bembibre says.
The team even analyzed the volatile organic compounds (VOCs) (挥发性有机化合物) in the book and the library. Using the data from the chemical analysis and visitors’ smell descriptions, the researchers created the Historic Book Odor Wheel to document the “historic library smell”. Main categories, such as “sweet/spicy”, fill the inner circle of the wheel; descriptors, such as “chocolate/cream”, fill the middle; and the chemical compounds likely to be the smelly source, like furfural, fill the outer circle. The researchers want the book odor wheel to be a tool that “untrained noses” can use to identify smells and the compounds causing them, which could address conservators’ concerns about material composition and historic paper conservation. And hopefully, smells of the past can be reproduced in the lab someday and museums and historians can use it to reconstruct a past we can no longer smell.

2 . Close your eyes for a minute and imagine what life would be like if you had a hundred dollars less. Also imagine what it would be like spending the rest of your life with your eyes closed. Imagine having to read this page, not with your eyes but with your finger-tips.
With existing medical knowledge and skills, two-thirds of the world’s 42 million blind people should not have to suffer. Unfortunately, rich countries possess most of this knowledge, while developing countries do not.
ORBIS is an international non-profit organization which operates the world’s only flying teaching eye hospital. ORBIS intends to help fight blindness worldwide. Inside a DC-8 aircraft, there is a fully-equipped teaching hospital with television studio and classroom. Doctors are taught the latest techniques of bringing sight back to people there. Project ORBIS also aims at promoting peaceful cooperation (合作) among countries.
ORBIS tries to help developing countries by providing training during three-week medical programs. ORBIS has taught sight-saving techniques to over 35,000 doctors and nurses, who continue to cure tens of thousands of blind people every year. ORBIS has conducted 17 plane programs in China so far. For the seven million to ten million blind people in China ORBIS is planning to do more for them. At the moment an ORBIS team is working on a long-term plan to develop a training center and to provide eye care service to Shanxi Province. ORBIS needs your help to continue their work and free people from blindness.
For just $38, you can help one person see; for $380 you can bring sight to 10 people; for $1,300 helps teach a doctor new skills; and for $13,000 you can provide a training programme for a group of doctors who can make thousands of blind people see again. Your money can open their eyes to the world. Please help ORBIS improve the quality of life for so many people less fortunate than ourselves.

3 . 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. |

6 . The sperm whale is an astonishing creature. It’s longer than a semi-truck, weighs more than 90, 000 pounds and is the largest member of the toothed whale family. It’s known to dive 6, 500 feet in search of food, and to stay down there for longer than an hour at a time.
Perhaps most fantastically, the sperm whale’s brain weighs as much as 20 pounds-the biggest of any species on Earth. But when it comes to brains, is size all that matters? There’s a lot we don’t know about the sperm whale’s intelligence because it’s difficult to carry out neurological (神经的) testing on such a huge marine mammal. But some clues point to sperm whales being much smarter than we give them credit for.
A 2021 study published in Biology Letters, for example, looked back to 19th-century historical logbooks from whalers. Researchers found that sperm whales were at first easy to catch-but almost immediately, the whales learned how to evade hunters and whaling success dropped by 60 percent. The study suggests that the whales passed information to one another through soundwaves to avoid being caught.
Animals that have big brains usually have a few things in common. They usually live long lives; for example, sperm whales can live for 70 years or longer. Additionally, they’re capable of complex behaviors and they tend to be more socia1. Whales may work together to hunt or communicate in a language all their own.
What’s more, humans, whales and dolphins all have spindle neurons in their brains. These nerve cells make us capable of deeper thought, such as reasoning skills, memory, communication and adaptive thinking. And like humans, whales have emotional intelligence- meaning they're capable of empathy, grief and sadness. Still, in proportion to (与…成比例)our body size, the human brain is bigger than that of the sperm whale.
Yet there’s still so much we don’t know about how smart sperm whales really are. And just like the whalers of a century ago, we have likely been underestimating marine mammals, whether large or small, for as long as we’ve known of their existence.

It was somewhere between spring and summer, and my mom and I were driving through the countryside. Back then, I was 13 years old, and always felt unhappy with Mom. But I didn’t know that this trip was going to be a special one.
A pot of flowers sat in the back seat, whose heavenly fragrance(香味)filled the car. Suddenly, in the middle of nowhere, my mom stopped the car. “What are you doing?” I shouted, fearing that the car had broken down and we’d be trapped there, so far from home. But that wasn’t the case. My mom jumped out of the car, grabbing(抓)the flowers from the back seat. “It’ll just be a minute,” she called back through the open windows.
I impatiently looked at the side of the road before finding a little sign showing that it was a nursing home. I looked back to the building, a little annoyed, as my mom reappeared ——empty- handed.
Before she started the car, curiosity drove me to ask, “Do you know someone there?” She shook her head. “Then what did you do with the flowers?” She smiled slightly, “I gave them to the receptionist (前台接待员).” “What?” She laughed at my confusion. “I told the receptionist to give the flowers to whoever needed them, especially those who haven’t gotten any in a while.”
I kept silent for a moment. Not long after we continued our driving, I spoke again, “Did you leave your name?” To this, she answered instantly, “No. Leaving flowers there for someone who will appreciate them makes me feel good, which is enough of a thank for me.”
Suddenly, still thinking about Mom’s deeds, I heard something burst loudly. It was our car that broke down! Nothing could be worse, because neither my mom nor I understood how to repair it, and we didn’t know where the garage was. It also seemed impossible to wait for any passer-by, since we had seen so few people along the way.
