3 . It seems rather obvious that facial characteristics are determined by our genes. But until recently geneticists(遗传学家) had very little understanding of which parts of our DNA were linked to our facial appearance.

An international team of researchers identified more than 130 chromosomal(染色体的) regions associated with specific aspects of facial shape. This is a critical first step toward understanding how genetics impact our faces, Live Science noted.

Researchers scanned the DNA of more than 8,000 people and analyzed dozens of shape measurements from their 3D facial images to look at the statistical relationships between about 7 million genetic markers—known locations in the genetic code where humans vary—and the facial features.

“When we find a statistical relation between a facial feature and one or more genetic markers, it points us to a very precise region of DNA on a chromosome. The genes located around that region then become our prime candidates for facial features like nose or lip shape,” Seth Weinberg, co-author of the study, wrote on Live Science.

Researchers discovered some interesting patterns after looking at the implicated(牵涉其中) genes at these DNA regions. Your nose is the part that is most influenced by your genes. Areas like the cheeks, which are highly influenced by lifestyle factors like diet, showed the fewest genetic associations.

There is also a high degree of overlap(重合) between the genes involved in facial and limb development. This provides an important clue as to why many genetic syndromes(综合症) are characterized by both hand and facial malformations(畸形). Some genes involved in facial shape may be involved in cancer, too. It explains why people treated for pediatric(小儿科的) cancer show some distinctive facial features.

So, can someone take your DNA and construct an accurate image of your face? It’s unlikely. The 130-plus genetic regions that were identified explain less than 10 percent of the variation in facial shape. But even if we understood all of the genes impacting facial appearance, prediction would still be a big challenge. That’s because facial features are affected by other factors as well, such as age, diet, climate and sun exposure.

Still, the knowledge of patients’ genetic information can be an invaluable tool in creating personalized treatment plans in fields like orthodontics(畸齿矫正学) or reconstructive surgery. For example, if someday doctors can use genetics to predict when a child’s jaw will hit its growth peak, it will help them decide the best time to intervene.

The world will observe International Museum Dayon May 18th. Since 1977, this day    1    (celebrate) by the International Council of Museums annually to raise awareness of the role that museums play in the development of society. The day is an excellent way of    2    (get) more of the younger generations interested in the history and culture available in museums. Every year, the organization    3    (decide) on a new theme. And the theme for 2023 is Museums, Sustainability and Well-being.

Reading is a unique human experience. Just by skimming our eyes over some words, we can    1    (mental) travel across time and space.

But reading can also be hard, especially when we’re faced with a difficult text.    2    (make) it an easier, more rewarding experience, you’d better read in print whenever possible. One reason for doing so is that our eyes are less likely to skim past printed words than those    3    screen. Plus, consuming content on a physical page helps the brain make a mental map of the information,    4    in turn makes it easier to remember details in future.

7 . I have a friend who bird watches. She feels comfortable whenever she’s doing it. If you ask her why she likes it, she will say things like “Well, birds are the world’s most magical creatures.” I have another friend who knits. She likes it because it’s satisfying, and has an astonishingly impressive impact on people for whom being able to knit gloves is out of reach.

As a term, “hobby” has always been of arguable meaning. Ask someone what they think a hobby is, and you’ll get a dictionary definition that they will have just looked up on their phones and, then, a passionate speech on all of the activities that can under no circumstances be put into groups as hobbies by their own highly unique and inflexible standards. Being online is not a hobby, apparently, nor is listening to music.

Hardly anyone knows what a hobby is, and this is particularly the case now that so many of us are spending our leisure time online arguing about these sorts of basic definitions with people, as the writer Max Read put it in an essay, “to whom the world has been created again every morning, for whom every settled argument of modernity must be rewritten, but this time with their engagement.”

Even taking these difficulties into account, however, it seems obvious that birdwatching and knitting are classic hobbies. They are enjoyable, involve practice and reward effort, and they are given immediate access to a group with the same interests. They are the sorts of hobbies advice columnists (专栏作家) have in mind when people write in about their imbalanced lives. It’s interesting, then, that not one of my two clearly hobby-having friends would admit to the practice.

They worried that their hobbies, which give them pleasure and keep them far from their computers, made them seem like they had too much leisure time and too Lew inner resources that would enable them to naturally avoid boredom. They are fully paid-up members of society, with busy lives, fulfilling interpersonal relationships and, again, hobbies that make them happy. It’s just that hobbies have an undeservedly bad reputation, one made worse by the Internet, like everything else.

The birdwatcher said the problem with having a hobby was that it made people seem like they were contributing and learning nothing. The knitter said that she personally connected hobbies with having no friends and no idea of what normal people do to have fun, Actually, they do not want to be seen as mad people who intentionally get away from the correct course.

Well, I enjoy certain light operas. I play music for my own amusement. And yes, I am an ordinary student, and that is not a sign of madness.

8 . I still remember how a pet mouse was popular among my classmates in Broadbeach State School. One day, my friends and I decided to buy a pet mouse. The pet shopkeeper wouldn’t sell us one until he got our parents’ letter that could show their permission for us to get a pet. So, having the neatest handwriting, I faked one. The store owner quickly saw through my handwriting and asked me to contact my mother to confirm the situation. My trick quickly failed, and it was all messed up.

My mum got very angry and felt that the punishment should fit the crime. Knowing that my writing was poor and always in need of improvement, she made me write letters to a few randomly selected relatives. One of them was my uncle whom I’d only met a few times when I was a kindergartner. I wrote a long letter detailing my life and listing my interests.

My punishment was complete. I forgot about this until I suddenly got a reply from my uncle.   “How lovely to hear from you,” he said, and went on to tell me all about his life. He’d love to hear about what subjects at school I enjoyed. And so started a correspondence(信件往来)that went on for several years. He turned out to be the most fascinating man.

Then out of the blue, he died. My mum took the phone call and she was shocked. She deeply regretted it as they had not really spoken for years because of their busy life and workload. I went upstairs and produced a box of letters, the last one being from just a few days before he had passed away. My mum began to read them and knew that although she hadn’t been in touch, I had grown close to him by writing to him, which relieved and calmed her. In fact, I then became close to his wife, whom I also wrote to for many years.

I often think about how that one naughty childhood crime led to such an enriching correspondence that stretched on for many years. It encouraged me to write to lots of other people in fact, and it’s something I keep up with to this day. Besides, receiving a letter is such a lovely surprise. Be bold and write to someone you maybe don’t know that well. Who knows where it will lead?

10 . On a cold November morning. Wade MacKinnon hiked around Mermaid Lake. In the _______ on the shoreline, something moved slightly and caught his eye. _______, he approached to find a balloon stuck in the branches of a bayberry bush. When he untied the string, he found a piece of paper at the end of it which read,

I’ve been missing you so much since you passed away. November 29 is my 10th birthday, but I will never receive your greetings...

Daisy”

It finished with a mailing address, almost 3,000 miles away. With tears in his eyes, Wade thought, “Such a young girl having to deal with _______. It’s awful!”

When back home, Wade placed the note in a drawer and _______ the balloon to the window of his room. Every day, the _______ of the balloon reminded him of little Daisy.

As the end of November was drawing nearer, Wade found himself thinking more and more about the poor girl. So he wrote a letter, put it into a birthday card and _______ mailed it with a book.

The _______ arrived just two days before Daisy’s birthday. When she opened it and found the card, “For a Dear Daughter...”, her heart _______.

“Happy birthday! I _______ to read your note, and feel sorry for you. I’m sure your daddy would want you to be happy. He loves you very much and will always be ________ you.” Tears began to roll down Daisy’s cheeks.
