Written in the first chapter of the book Pride and Prejudice is an extraordinary sentence of which even a person who has had only a brief look upon the book will not fail to receive a deep impression — It is a truth universally acknowledged that a single man in possession of a good fortune must be in want of a wife. In terms of Sherlock Holmes, we'd better alter the sentence into “It is a fact universally accepted by readers throughout the world that an excellent book in possession of our famous detective Sherlock Holmes is undoubtedly a masterpiece of all times.” Perhaps this is one of the most obvious explanations for the unrivaled popularity of “Holmes series” in the field of detective stories. Overwhelmed by the recommendations provided by my friends, I decided to take a look on this Sherlock Holmes and the Duke's Son originally published by Oxford University Press.

    As a whole, this book is about a case concerning the Duke's missing son. Arthur, the Duke's son, was found out in a certain morning to have disappeared, accompanied with which was also the disappearance of the German teacher. The school master Dr. Huxtable then turned to the famous detective of the time Sherlock Holmes for help. Realizing how tough and important the case is, Holmes immediately made up his mind to accept the case and followed Dr. Huxtable back to Mackleton by train. Having formed a rough idea about the whole matter, Holmes probed into the case immediately and had a careful investigation of the entire area shortly after the arrival, during the process of which he discovered the body of the German teacher Heidegger. Finally, primarily due to his prominent ability as a detective, he managed to unravel the mystery.

    Having once started reading this fiction, I was completely immersed in the mysterious story. At the beginning, unlike other detective stories, this story first delineates the client's strange behavior at length to indicate the severity of the incident in order to attract the readers to continue reading it. As is known to all, vivid depiction is essential to detective stories as it makes the story more authentic and attractive. Therefore, trying to present a “real world” to his readership, Sir Arthur Conan Doyle, author of the original “Holmes series”, has skillfully arranged the plots of the whole story from the perspective of Dr. Watson, a friend of Homes'. In this way, he elaborately (精心)depicted every scene and character in the book. Apart from the special start, the ending of the whole story, being dramatic but reasonable, is certainly an outstanding one. After all, except the author himself, who knows that the Duke's seemingly ordinary secretary is in fact the Duke's bastard(私生子)? In addition, who knows that the Duke actually has already been acquainted with the whole thing before Holmes solves this complicated problem? Yet, surprising as it is, this ending seems so natural that it fits all the plots of the story perfectly well. Closing my eyes, I can even “see” the story happening just like watching a film.

    As far as I am concerned, nothing is more admirable and surprising in the hero Sherlock Homes than his profound knowledge which has certainly assisted him a lot when he was studying the case. Take the bicycle tyres for instance, Holmes is capable of recognizing 42 different varieties of bicycle tyres. Except for his illimitable knowledge, Holmes also specializes in arranging the facts in order and then finding the fact leading him to a great discovery or even the truth itself. In this case, after getting rid of unrelated facts, Sherlock Homes eventually grasped the clue and discovered the amazing fact.

    Needless to say, as a world-renowned masterpiece, Sherlock Holmes and the Duke's Son has attracted and is still charming numerous readers from all corners of the world and people from all walks of life. The “Holmes series” has already set up a standard against which all the following detective fictions are measured. Sherlock Holmes, beyond all doubt, has been a name firmly rooted in people's memories. Although Dr. Watson's closing The Case Book of Sherlock Holmes in 1927 was a great pity to the readers, the discontinuance of the entire “Holmes series” may have actually added to the legendary stature of Sherlock Holmes.

    Time flies, but the tracks of time remain in books and museums. This is what made a recent tragedy in Brazil even more terrible.

    On Sept.2, a big fire ripped through the National Museum of Brazil. "Two hundred years of work, research and knowledge were lost," Brazilian President Michel Temer wrote on Twitter after the fire. "It's a sad day for all Brazilians."

    Most of the 20 million pieces of history are believed to have been destroyed. Only as little as 10 percent of the collection may have survived, Time reported. Among all the items, there were Egyptian mummies, the bones of uniquely Brazilian creatures such as the long－necked dinosaur Maxakalisaurus, and an 11,500－year－old skull called Luzia, which was considered one of South America's oldest human fossils.

    Besides these, Brazil's indigenous(本土的，土著的) knowledge also suffered. The museum housed world－famous collections of indigenous objects, as well as many audio recordings of local languages from all over Brazil. Some of these recordings, now lost, were of languages that are no longer spoken.

    "The tragedy this Sunday is a sort of national suicide, a crime against our past and future generations," Bernard Mello Franco, one of Brazil's best－known columnists, wrote on the O Globo newspaper site.

    The cause of the fire is still unknown, as BBC News reported on Sept. 3. After the fire burned out, crowds protested outside the museum to show their anger at the loss of the irreplaceable items of historical value.

    According to Emilio Bruna, an ecologist at the University of Florida, museums are living, breathing stores of who we are and where we've come from, and the world around us.

    Just as underwater grass floats on the surface if it loses its roots, a nation is lost without its memories. The fire at the National Museum of Brazil teaches the world an important lesson: We should never neglect history.

    With all the wars, fighting and sadness in the world today, it's not only necessary, but also essential to have a good sense of humor just to help us get through each and every day of our lives. Putting a smile on someone's face when you know they are feeling down in the dump, makes me feel good and warms my heart.

    How would you feel if you could not joke around with your wife, husband, child, co-worker, neighbor, close friends, or even just someone that you are standing in line with at your corner store? I am always saying things that make others smile or laugh, even if I don't know the person I'm joking around with. My Grandma always found humor in everything she did, even if it was the hardest job anyone could imagine. This not only relieves stress in any situation, but also is common courtesy(礼貌)to speak to others that are around you.

    I know of a few people that don't have a funny bone in their bodies, as they say. Everyone around them could be rolling on the floor after hearing a great joke and they would sit there without the slightest smile on their face. They don't get the joke that makes others laugh. I am busting a gut while they just sit there, looking at me as if I were from outer space. How can people not get a really funny joke?

    Laughing is essential to keep your stress levels under control. Without humor we would find ourselves with a lot of psychological problems, or on a lot of medications to keep us from going crazy. There is too much sadness in this present world. It drives people crazy. We all need to find a way to ignore the sadness and bring a little light into our lives. So, I believe our best medicine is to get together and tell some jokes and have some fun laughing together.

    Better known by his stage name Kun, Cai Xukun is, without a doubt, one of the most popular stars in China.

    On July 26, the 21-year-old dropped his new single Young. Within just 20 seconds, it reached 1 million views and in only 3 days topped the music charts of Tencent's QQ music.

    Cai wrote the song by himself to share his understanding of modern-day youth. The singer has mixed R&B with electronic music to make his new beat cheerful. One reviewer wrote on QQ Music: "When you listen to the song, you just seem to go back to youth again."

    August 2 is Cai's birthday, and the song was a gift to himself. The singer hopes that he can always have the courage to follow his love of music, ignoring what anyone says. "My works are like my children and I have put my best effort into them. I want every piece of my work to have my own spirit in it. I feel more enjoyment when I am performing my own work." He told the Global Times.

    To find new inspiration, Kun attends different kinds of musical performances－from festivals to opera houses. "I just like to do everything, all for my music, all for my art," he told i-D.

    With talent and dedication(专注) to music, Cai is expected by many to make his mark in the competitive Chinese music industry.

Plastic is everywhere, from the Arctic ice to vital organs in the human body. In fact, previous estimates suggest that the average person swallows a credit card-worth of microscopic plastic particles(颗粒) every week. But new research shows that this could actually be an understatement. 

Microplastics are plastics smaller than 5 millimeters, found in industrial waste, beauty products, and formed during the degradation of larger plastic pieces. Over time, they break down into even smaller nanoplastics. These tiny particles can pass through our intestines and lungs into our bloodstreams, reaching vital organs like the heart and brain. 

While the idea of eating plastic is unsettling in itself, the major concern here is that these plastic particles contain chemicals that can interrupt our body's natural release of hormones, potentially increasing our risk of reproductive disorders and certain cancers. They can also carry toxins(毒素) on their surface like heavy metals. 

In the past, researchers have shown bottled water can contain tens of thousands of identifiable plastic fragments in a single container. However, until recently, only the larger microplastics were detectable with available measuring tools, leaving the area of nanoplastics largely a mystery. 

Using Raman microscopy (显微镜学), capable of detecting particles down to the size of a flu virus, the team measured an average of 240, 000 particles of plastic per liter of bottled water, 90 percent of which were nanoplastics, a revelation 10 to 100 times larger than previous estimates. 

These plastics likely originate from the bottle material, filters used to "purify" the water, and the source water itself. "It is not totally unexpected to find so much of this stuff, " the study's lead author, Columbia graduate student Naixin Qian, said in a statement. His team hopes to expand their research into tap water and other water sources to better inform our exposure to these potentially dangerous particles. "The idea is that the smaller things get, the more of them I reveal, " he added.

My mother has always been one of those rare people that sees the good in everyone and does good things "just because". Life hasn't always been kind to her; she lost my oldest sister to leukemia (白血病) in 1963 and my father in 2007 after nearly 51 years of marriage.

She's had her ups and downs but has always 1 a positive, sunny outlook on life and been very 2 to people.

One day, my little sister fell and hurt her ankle, desperately needing a 3 to the hospital emergency room. My mother immediately 4 into crisis mode, packed my sister into the car, and drove to our local hospital. In such a 5 , my mother didn't call to tell my father. When she got to the hospital, she realized she needed to 6 with my father immediately.

While waiting for my sister to be examined, my mother 7 her way to the pay phone to place her call. She put her coin in, called my father and told him everything. After she hung up, the phone 8 several additional coins that Mom wasn't owed.

Realizing that the phone was 9 , my mother decided to leave the 10 coins by the phone. She told us that in a crisis, people might not remember to bring 11 with them to make that emergency call.

I've often thought about her 12 from an adult's perspective I realize that someone seeing the money by he phone may have 13 taken it because not everyone was as 14 as my mother. But I like to believe that my mother's faith was 15 and that someone who needed them found the coins waiting there.
