1 . Google Flights reveals new feature to help travelers save money

Regular users of Google Flights might notice a new feature the next time they go to the site to check out airline schedules and compare flight prices.

The new feature officially announced on Monday morning in a news release is Google guidance on the cheapest time to book a flight, which adds price tracking alerts and a price guarantee option already in place.

Cheapest time to book: Google Flights said starting this week, searches that have reliable trend data will let users see in what time frame prices have typically been lowest. Users can then better decide whether to book now or later, Google said in the release.

Take flights from New York to Miami, for example, the cheapest time to book is usually from Sep 13 to Dec 7. Prices during this time are $59 cheaper on average.

Price tracking: Users who want to wait for lower fares before booking can use a price tracking feature that “can do most of the heavy lifting for you,” Google said.

Price guarantee: On some flight results, users might notice a price guarantee badge (标志) pop up (this won’t happen on every use). If you book one of these flights, Google said it will monitor the price every day before takeoff.

“If the price does go down, we’ll pay you back the difference via Google Pay. These price guarantees are part of a pilot program available for select Book on Google itineraries (行程) departing from the U. S.,” Google said in the release.

2 . The Nobel Prize in Chemistry 2023 was awarded to three American scientists Moungi G. Bawendi, Louis E. Brus and Alexei I. Ekimov “for the discovery and development of quantum (量子) dots”. They are so tiny that their size determines their properties. These smallest components of nano (纳米) technology now spread their light from televisions and LED lamps, and can also guide surgeons when they remove cancer tissue, among many other things.

Everyone who studies chemistry learns that an element’s properties are governed by how many electrons (电子) it has. However, when matter contracts to nano-dimensions quantum phenomena arise; these are governed by the size of the matter. The Nobel winners in Chemistry 2023 have succeeded in producing particles so small that their properties are determined by quantum phenomena. The particles, which are generally known as quantum dots by scientists, are now of great importance in nanotechnology.

“Quantum dots have many fascinating and unusual properties. Importantly, they have different colours depending on their size,” says Johan Åqvist, Chai r of the Nobel Committee for Chemistry.

Physicists had long known that in theory size-dependent quantum effects could arise in nanoparticles, but at that time it was almost impossible to sculpture in nanodimensions. Therefore, few people believed that this knowledge would be put to practical use.

However, in the early 1980s, Alexei Ekimov succeeded in creating size-dependent quantum effects in coloured glass. The colour came from nanoparticles of copper chloride (氯化铜) and Ekimov demonstrated that the particle size affected the colour of the glass via quantum effects. A few years later, Louis Brus was the first scientist in the world to prove size-dependent quantum effects in particles floating freely in a liquid. In 1993, Moungi Bawendi revolutionised the chemical production of quantum dots, resulting in almost perfect particles. This high quality was necessary for them to be used in applications.

Quantum dots are thus bringing the greatest benefit to humankind. Researchers believe that in the future they could contribute to flexible electronics, tiny sensors, thinner solar cells and quantum communication — so we have just started exploring the potential of these tiny particles.

4. What can we infer from the Nobel Prize in Chemistry 2023?

A．Innovation is the most important thing.

B．Practice is the only criterion for testing truth.

C．The development of science and technology is endless.

D．Technology from quantum dots is constantly improving.

In Xia, Shang and Zhou dynasties, ancient China established itself a complete ceremony system.     3     (drive) by the system, it’s widely believed that it’s impolite to serve     4     alcohol, which helped greatly promote the     5     (popular) and use of bronze (青铜) drinking vessels,     6     (make) them a significant symbol of bronze culture in this period. The drinking vessels came with a variety of shapes and sizes.

Drinking wine was     7     (extreme) popular in the Tang Dynasty. Among more than 40,000 poems included in the Complete Tang Poems, there are up     8     5,400 poems written about wine.

7 . AI Can Bring Great Benefits to Human Beings

The explosion of progress in AI in recent months has surprised even the scientists and engineers who specialize in applying AI to real-life tasks. Several big companies started amazing new programs in a short time, including OpenAI’s ChatGPT, Microsoft’s Bing and Google’s Bard. “A few years ago I never would have imagined we would advance this far this soon,” says Zhe Jiang, a University of Florida researcher who studies applications of AI. Here are some examples of AI applications.

In April, a study published in Nature showed that an AI program was as good as or better than human experts at spotting heart problems in patient ultrasound (超声波) images. That is to say, AI is able to match or go beyond human doctors at catching cancers and other disorders by scanning images and tissue samples.

Some drug companies are already relying heavily on AI to help find promising new drugs. For example, PsychoGenics, a company specializing in drugs for mental disorders, is improving on the inefficient, inexact and costly process of testing new mental drugs on mice, which typically takes five years. By using AI instead of lab staff to observe the effects of new drugs on mice, the company can test more drugs with greater accuracy at a tenth the cost and two years faster.

With 56 million Americans over 65, the high cost and short supply of eldercare workers, eldercare robots have already stepped in. Without using the recent Al advances, robots already watch over seniors with electronic eyes, fetch small items, answer questions. Some of them can already start conversations with seniors, help them recall what happened, and then report the results to family members. Soon, the power of such devices to interact with people will improve greatly. “Caregiving and companion robots equipped with the latest AI can provide ‘empathy’,” says Forrester’s Curran. “They can tell the difference between a senior who is searching through a drawer, and one who is struggling to open a drawer,” he explains.

8 . Here in eastern Spain, human towers are very popular. The tower sometimes falls because it’s so high. I used to ________ to be up there, but for the past year, I’ve been practicing ________. So today, I finally became a casteller — a castle constructor.

My friend Tomeu was also part of our team. Tomeu had been a casteller before. “What if I’m not ________ for this?” I asked him. Tomeu smiled, “We’re never ready, Jordi. Just trust those below who ________ you up and yourself. Have faith!”

It was our turn. We first made the ________ for our tower. My father and three of the strongest men formed a ________ facing each other as they held each other’s arms tightly. Four more strong men stepped behind, each wrapping his arms around the ________ of a man and giving him a bear hug. Four smaller men climbed onto the backs of the ________ group and stood on their shoulders.

Our base was solid, so my father ________ and we continued building. After the sixth tier (层) was set up, it was my turn.

“Have ________!” Tomeu said to me again. I passed the first two tiers ________ because the people were leaning forward. But the higher I went, the more unstable the tower became. By the time I reached the sixth tier, the tower below me ________ a bit. My heart began a crazy dance in my chest. I took a deep breath to ________ myself. Reaching deep inside to feel my ________, I rose slowly out of my crouch (蹲伏) and straightened my knees. I waved my hand to the judges, meaning our tower was ________.
