21、An optical(光存储的)chip has been developed by a multi-institution research, group that has the potential to train machine learning hardware.
Training of modern-day artificial intelligence (AI) systems costs several million dollars in electric power and requires supercomputer-like equipment. This increasing AI desire leaves an ever-widening difference between computer hardware and demand for AI. Simply, photonic chips(光子芯片)have become a possible solution to deliver higher computing performance. However, though they’ve shown improved heart operations in machine intelligence used for data sort, photonic chips have yet to improve the actual front-end learning and machine training process.
Machine learning is a two-step procedure. First, data is used to train the system and then other data is used to test the performance of the AI system. A team of researchers from sever-al universities set out to do just that. After one training step, the team observed a mistake and reset the hardware for a second training cycle followed by additional training cycles until an enough AI performance was reached. Thus far, photonic chips have only shown an ability to sort and conclude information from data. Now, researchers have made it possible to speed up the training step itself.
This added AI ability is part of a larger effort around photonic tensor cores(张量核心) and other electronic-photonic application-specific combined circuits that use photonic chip producing for machine learning and AI applications.
“This novel hardware will speed up the training of machine learning systems and make the best of what both photonics and electronic chips have to offer. It is a major jump forward for AI hardware speeding-up,” said Volker J. Sorger, founder of a company.
“The training of AI systems costs a great deal of energy and carbon footprint. For example, a single AI transformer takes about five times as much CO2 in electricity as a gasoline car spends in its lifetime. Our training on photonic chips will help to reduce this spending. ”
【1】What can we infer about photonic chips from paragraph 2?
A.They still have failings.
B.They can soon be widely used.
C.They are beyond spending on AI.
D.They can provide more electric power.
【2】What do the researchers from several universities suggest?
A.Machine learning has two steps.
B.Mistakes are unavoidable in research.
C.Speeding up the training step is possible.
D.Photonic chips cannot sort information.
【3】What is Volker’s attitude to photonic chips?
A.Favourable.
B.Careless.
C.Doubtful.
D.Negative.
【4】What is the best title for the text?
A.Slowing Up AI’s Training
B.Reducing Machine Learning Spending
C.Photonic Chips to Reduce the Cost of Computers
D.Photonic Chips to Train Machine Learning Hardware
22、Michelle was a student at University of California, Los Angeles. She is here to tell us how she feels about the city.
What were the best things about Los Angeles?
One of my favorite things about Los Angeles is the weather. I hate the cold and it never really gets that cold there. Plus, most of the time it’s usually sunny, which is good because I love going to the beach during the summer. There’s so much to do at the beach, but my favorite thing in L.A. was having a picnic on the sand with my friends.
What were the worst things about being there?
I disliked having to drive everywhere to get around because the city is so spread out. Los Angeles has a lot of traffic and sometimes it takes a long time to get somewhere close by just because the streets are so crowded. Also, a lot of people complain about the pollution.
Did you have any problems there?
Just the normal problems of living in any city, like watching out for pickpockets. Some people think Los Angeles has a lot of crime, but I think it’s as safe as any other city. Also, many people think driving is difficult because there is a lot of traffic and road rage (路怒症), but it just takes a little practice and a lot of patience.
What are the people like in Los Angeles?
There are all types of people in Los Angeles since the city is pretty diverse. For the most part, though, most of the people are friendly, calm and relaxed. Some people say that everyone in Los Angeles is beautiful, but I think that’s just a stereotype.
Would you go back to Los Angeles?
Certainly. Los Angeles is one of my favorite cities in the world. I love the fact that it has all the nightlife and shopping of a big city, but also has access to beaches, parks, mountains and other places you can’t usually find in large cities. Between the weather and the beaches and all the fun things to do, it’s a great place to be.
【1】We can learn from the text that Michelle _____.
A. hates the heavy traffic in Los Angeles

23、A family is a collection of people who share the same genes but cannot agree on a place to pull over for lunch. Ed and I, plus his parents and sister Doris and eight-year-old niece Alisha, are on a road trip to Yosemite. Ed wants Subway, I want. In-N-Out Burger, Doris wants Sonic. In the end, we compromise on McDonald’s, where Alisha will get an action figure.
It’s a three-hour drive to Yosemite, but we’re taking a little longer, as we’re working in a tour of Highway 80’s public restrooms. As the saying goes, “Not one bladder(膀胱)empties but another fills.” Many of these restrooms belong to gas stations. I prefer them to the high-tech ones on planes.
We get back on the road. Ed is driving now. When all the tabloids(小报)have been read, the travel has grown tedious and anyone under age 12 asks “Are we there yet?” at ever-shortening internals. Just outside Manteca, California, we stop for coffee. At a Starbucks checkout, Ed buys a CD of Joni Mitchell’s favorite musical picks. The hope is that it will have a calming effect.
As we pull back onto the highway, it starts to pour. Then something amazing happens. As we climb the mountain, the rain turns to snow. The pines are spotted with white. We’re struck dumb(说不出话)by the scene outside. For a solid 15 minutes, everyone forgets about their bladder, their blood sugar and the temperature. Alisha has never seen snow, so we pull over to make snowmen and catch snowflakes on our tongues. Then Ed realizes we need tire chains, and we have to turn back and drive 30miles to Oakhurst. “Good,” says Doris. “There was a very nice restroom there.”
【1】Where does the family have lunch?
A. At Sonic. B. At Subway.
C. At McDonald’s. D. At In-N-Out Burger.
【2】Why does the family spend so much time going to Yosemite?
A. They stop a few times for gas. B. They go to the toilet frequently.
C. They are affected by the bad weather. D. They need to rest and refresh themselves.
【3】What does the underlined word “tedious” in Paragraph 3 probably mean?
A. Boring B. Difficult.
C. Educational. D. Comfortable.
【4】How does the family feel when it snows?
A. Sorry. B. Excited.
C. Worried. D. Relaxed.
24、Canadians are blessed with an abundance of natural wonders with enough lakes, mountains and rivers to explore for a lifetime. We’ve also got some of the most shocking waterfalls on Earth.
Pissing Mare Falls-Gros Morne National Park, Newfoundland and Labrador
Pissing Mare Falls may have a funny sounding name but they' re no joke: in fact, they' re one of the highest waterfalls in Canada. Located in the beautiful Gros Morne National Park, the falls are only accessible by boat tour.
Takakkaw Falls-Yoho National Park, British Columbia
Takakkaw translated from Cree loosely means the "magnificent", and it's a suitable word for the second-highest waterfalls in Canada. After a steep drive up a winding road, these falls are only a short hike from the parking lot along a wheelchair accessible path.

26、阅读下面短文,根据其内容和所给段落开头语续写一段,使之构成一篇完整的短文。
When parents take part in our school events, it is usually embarrassing. A few weeks ago, it was my mom who played the embarrassing parent role.
While my mom and I were shopping, we ran into my teacher, who mentioned that the school didn’t have a music teacher to help our class put together a performance for Winter Fair. And, right then and there, my mom said, “I know the perfect song-and-dance. I’ll teach it to the kids!”
Before I could say “Please don’t,” my mom had agreed to come to my class every morning at 9:30 for a week. Oh, and just to be clear, she is not a professional entertainer at all; my parents run a small grocery store.
“Um,” I said on our way home, “are you sure this is such a good idea?”
“Of course!” she said. “We’ll have fun!”
“OK, guys,” my teacher said at 9:28 on Monday. “We’re going to stop silent reading a little early because a special guest is here to help us with a performance for Winter Fair. Let’s welcome Arizona’s mother.” I looked up and discovered my mom standing at the front of the room wearing the world’s funniest big hat.
“I’m super excited to be here with you!” my mom said. “I’m going to teach you a fun little song-and-dance I learned a few years back, when I did some theater in college. Here it goes!”
Oh, please, oh, please, I said over and over in my head, let there be a fire drill, or an urgent meeting, or a power cut, or anything to stop my mom from completely embarrassing herself—and me!
But apparently, my mom was not at all concerned about looking silly. She turned on some background music and started singing and dancing away.
I closed my eyes, covered my ears, and sank as low as I possibly could in my chair.
