Washington DC holds a special place among the American cities. The route below includes some of the city's big-hitting museums and unexpected treasures.
Phillips Collection
Founded in 1921 by art collector Duncan Philips and his wife Marjorie, the Philips Collection was the first museum of modern art in the US and continues to change and expand with new exhibits The personal collection is a rollcall of some of the most celebrated names, including Monet, Picasso, and Van Gogh.
Go-Go Museum & Cafe
Hire a bike to cross the Anacostia River and seek out one of the city's newest museums. As its name suggests, the Go-Go Museum and Cafe celebrates go-go, the lively style of funk known for its unique beat and vocals. Go-go has its roots in the city's African American community, with local guitarist Chuck Brown known as the "Godfather of Go-Go"
National Mall
Make the short walk south—past the White House—and the National Mall outspreads like a vast, green carpet, between the Lincoln Memorial and the United States Capitol, with the towering Washington Monument at the heart of it. Near a two-mile grass walkway is the Library of Congress the largest library in the world. At a leisurely pace, a full lap of the Mall can easily take over two hours, so allow time to take it all in.
Rubell Museum
Back across the river, on 1st Street SW, the Rubell Museum is a fun place with contemporary art. This is one of the largest private collections of modem works in North America, collected over a period of nearly 60 years by Don and his son. See them showcased through a collection of paintings, sculptures, videos and photography
Rachel began rowing when she was 53, after spotting a six-oar rowing boat in Bristol harbour Fascinated by its size and distinctive appearance, she was encouraged to do a trial run. "As soon as I got on the water. I was hooked," she says. "Feeling your whole body working and the fresh air on your skin is amazing."
It wasn't until 2017, though, that Rachel's Atlantic plans were born. She had experienced back pain occasionally since her teens, and then one day, while at home, she was suddenly unable to walk
"I knew I needed to keep myself healthy-minded, so I began thinking of things I could look forward to after I had surgery," she said.
Rachel had retired a few years earlier, when she moved from Bristol to the coast to help look after her elderly mother. "Every time I decided to go on holiday or leave, I'd get a call to find out mum was in hospital. Eventually, I stopped making plans," she says. "But as soon as I was disabled myself, it made me realize that I had to do something to make my own life count."
After successful surgery, Rachel began driving around the country to meet other women who had undertaken endurance rows. Hearing the experiences and advice of other athletes gave Rachel the confidence she needed. Soon after, she heard that a new boat maker was building a team for a maiden voyage across the Atlantic. So Rachel began intensive training, even adapting her garden into a gym during the Covid lockdowns. Finally, she set off in 2021.
Empowered by this successful expedition, she has been inspired to keep pushing the limits, planning to break a few world records by rowing around the UK at 64, and motorcycling through the Himalayas later in the year. "I know my body is changing and the physical challenge is greater, but that just makes me want to achieve even more," she says.
The tale of the ants who scared the elephants to help the lions catch the zebras may sound like a children's fairy tale, but it is a true story with an unhappy ending for the big cats. Lions in Kenya are being pushed closer to endangered situation because the acacia trees that they rely on for cover while hunting zebras are dying. leaving them nowhere to hide while hunting.
Scientists were surprised that acacia trees were able to grow fast in the Nature Conservancy in central Kenya, as there are so many leaf-eating mammals such as elephiants and giraffes that would normally eat up the tree leaves.
The acacias' secret weapon is a species of ant that lives in the tree. The trees are historically protected from leaf-eating animals by this species. In return for their home, the ants defend the trees from huge plant eaters, like elephants, giraffes, an arrangement ecologists call mutualism(共生).
About 15 years ago, unnoticed by environmentalists, a new species of ant slipped into the region. It is thought that this invasive species, known as the big-headed ant, often found hidden in the wood used in construction, was brought to the area by human activity. These ants set about attacking and destroying the ants that used to defend the trees. The new ants do not make any effort to protect the trees, leaving the acacia trees defenceless. This has set off a chain of events, resulting in a shift in predator-prey(捕食者—猎物)behaviour that may further endanger populations of lions, researchers said. "The lions rely on the tree cover to hunt and hide before attacking zebras. Less tree cover means lions are not as successful at ambushing(伏击)their prey."
Intel has created the world's largest neuromorphic(神经形态) computer, a device intended to imitate the operation of the human brain. The firm hopes it will be able to run more complicated AI models than is possible on conventional computers.
A regular computer uses its processor to carry out operations and stores data in separate memory, but a neuromorphic device uses artificial neurons to both store and compute, just as our brains do. This removes the need to transmit data back and forth between components, which limits the speed of current computers.
It also means "brain-like" computers can be more energy efficient. Intel claims its new Hala Point neuromorphic computer uses 1% of the energy a conventional machine takes when running optimization(优化)problems, which involve finding the best solution to a problem given certain restrictions. Mike Davies at Intel says that despite its big power, Hala Point is about as big as a microwave oven. Intel suggests that a machine like Hala Point could create Al models that learn continuously, rather than needing to be trained to learn each new task, as is the case with current models.
But James Knight at the University of Sussex, UK says current models like ChatGPT are trained using graphics cards operating in parallel(平行), meaning that many chips can be put to work on training the same model. But as neuromorphic computers work with a single input and can't be trained in parallel, it is likely to take decades to train something like ChatGPT on such hardware, not to mention make it learn continually, he says.
While today's neuromorphic hardware still needs to be improved, says Davies, it could one day take pre-trained models and let them learn new tasks. "This is the kind of continual learning problem that we believe large-scale neuromorphic systems like Hala Point can solve in the future," he says.
If you lost your watch after a football match, you'd notice it. If you came home to find your jewelry drawer on the floor, you would probably cry out, "We've been robbed!" However, people hardly notice when they're robbed of something much more valuable. .
We are miserably aware that we never seem to finish our work. But we do. The problem is that we let people and devices take it from right under our noses
They're usually the most important people in our lives: the boss, colleagues, family and friends. "Got a minute?" they ask. And just like that, you're robbed again of something valuable that you can never get back.
If you're like most people, you lose three to five hours every day. It goes to interruptions; that's where. If you want to get that stolen time back and use it the way you desire, here's what to do:
First of all, count it up. Don't be fooled by that "Got a minute?", because such interruptions throw you off tasks and leave you frustrated of having to make up for time lost. You need to Count it all up. Secondly, explain to your time robbers that you have their best interests at heart so that they will not be disappointed. Lastly, work alone, totally focused on important tasks and stop losing your precious time.
A. Don't take it into account
B. That is their precious time
C. Who are these "time robbers"?
D. Worse yet, you don't realize where the time goes
E. We complain that we simply don't have enough time
F. Total up the time you're losing to interruptions every day.
G. They never know what prevents them from the good stuff
I've loved to sew(缝制) all my life ever since I was 7. As a teenager. I began to 1 and sew my own outfits. In my 20s, I began to buy 2 and out-of-date clothes to upcycle and refashion.
However, about 10 years ago, when I was 3 a beautiful long blue evening dress. I stopped. From a hidden pocket I pulled out an old 4 . In it a young woman was 5 the very same blue evening dress. A long silver chain necklace hung 6 down the front of the dress. Holding a black purse, she had a soft 7 . Who was she? Did she wear it to the theater? And I was now tearing it apart. I felt 8 .
I mentioned my 9 and guilt to my daughter. She said, "Mom, you should be 10 of your upcycling and your sewing creations. You are keeping these clothes from being 11 away If you find objects in the pockets, consider it a 12 ."
I decided to show 13 to this upcycling discovery—by displaying it on a beard in my sewing room. It made me 14 refashioning and upcycling clothes even more. But I have learned to be a little 15 when dealing with clothes and approach pockets more carefully.
Famous for silk production and traditional gardens. Suzhou, the city of just over 10 million people (offer) a week of free subway rides during the 2024 Lunar New Year period to passengers in Hanfu.
(dress) up in Hanfu to visit local attractions has become a popular way to express one's holiday spirit in China in recent years, (especial) among youth. "The preference is an important symbol of the Chinese cultural renaissance." Song Weixia, a brand (design)from Anhui says. "There's more to this fashion flashback than just holiday spirit. It is the rise in the desire (appreciate) Chinese culture among young people in recent years that counts. In fact it's an expression of a nation feeling (confidence) with its culture."
"There is a group of people wear it as a trend," she says. "But it's important to preserve the tradition an accurate way so the tradition doesn't get (lose)." In the end. Song says she doesn't focus too much on what clothes she wears rather how she spends time with her loved ones, as "that's the core tradition of Lunar New Year."
She was the new girl in our school, Anna. She had the prettiest face in our school and she had very nice manners, but I hated her. I was jealous(妒忌的) of her as I was the most popular girl in the school and I didn't want her to be liked by everyone, so I spread rumors(谣言) about her but she never looked at me with anger.
I bullied Anna mentally most of the time and I never realized that I was that rude. She would cry bitterly every time I spoke ill of her parents. Anna was being liked by more and more people because of her good attitude. I was really angry with her.
One day, I saw that there was a poster for our Prom(正式舞会). I wanted to become the Prom Queen this time. When the Prom Princesses were announced, Anna was one of them. My heart was burning with jealousy as I had the fear that she might be chosen for Prom Queen.
I saw Anna buying a dress for her Prom from the same mall I was buying mine. We chose the same dress but she was looking more brilliant than I was with her beautiful long brown hair. When she was going back home, I followed her and went into her house. Her house was very small and I didn't see any of her family members there. I tore her dress in front of her. Her beautiful eyes were filled with tears but I didn't feel sorry for her.
Several days before the Prom, I was walking on the street while listening to a song. The volume was so high that I did not realize a car was behind me, honking(按喇叭) to warn me that it was in a very fast speed.
注意:
1. 续写词数应为150个左右;
2. 请按如下格式在答题卡的相应位置作答。
Suddenly, someone pushed me out of the way.
Finally, the doctor came out and said that Anna would be fine soon.
