22、   It’s safe to say that OLED displays are the gold standard on smartphones these days. Some OLED panels are better than others, and the Galaxy S21 Ultra features what may well be the best one to date — the device’s display is definitely the most power efficient. In fact, Samsung developed a new ultra-low-power OLED display for the new phone, and it reduces energy consumption by up to 16%.

The way Samsung did this is a little technical. OLED displays in general don’t require a backlight like LCD displays. Instead, each individual pixel(像素) is made from an organic carbon-based material that lights up when electricity is applied. OLED displays are made up of a range of layers, which serve different purposes. The core of the new OLED display tech is that Samsung found a way for electrons to flow faster between these layers, while at the same time creating a brighter light.

The power-consumption savings will be put to good use, as 5G phones can take up a little more energy than non-5G phones.

It’s important to note that the new display tech is only available on the Galaxy S21 Ultra — not the standard Galaxy S21 and Galaxy S21+. All three of the devices offer up to a 120Hz refresh rate. However, the Galaxy S21 Ultra has a 1,440p resolution(分辨率). And while the standard Galaxy S21 and S21+ have refresh rates that vary between 48Hz and 120Hz, the Galaxy S21 Ultra can go as low as 10Hz, which also helps save on energy consumption.

Samsung has been a leader in display tech for a long time, and it looks like that will continue well into the future. The company says that it holds 5,000 patents that involve the use of organic materials for displays. Hopefully, this new tech will be brought to lower-end phones over the next few years, or at least to the entire Galaxy S22 series next year.

【1】What is the advantage of Samsung’s new tech?

A．It makes electrons flow faster and light brighter.

B．It requires an organic carbon-based material.

C．It makes the OLED display more functional.

D．It has a new ultra-low-power OLED display.

【2】What makes the new display tech unique on the Galaxy S21 Ultra?

A．Changes that differ from other devices.

B．High resolution and low refresh rate.

C．Standard modern equipment.

D．Low energy consumption.

【3】What can we infer about Samsung display tech from the last paragraph?

A．Its display of patents relates to organic materials.

B．It has just become the leader in display technology.

C．It will be used on low-end phones over the next few years.

D．It will definitely be used in the entire Galaxy S21 series next year.

【4】What is the text mainly about?

A．Samsung has developed the most popular new phone.

B．The Galaxy S21 Ultra may have the best features up to now.

C．The difference among the Galaxy S21 Ultra, Galaxy S21 and Galaxy S21+.

D．Samsung’s new display tech makes the Galaxy S21 Ultra even more power efficient.

23、   HOW BIG should a business team be?It is an enormously important issue for companies, Teams that are too small may lack the skills required to get the job done:teams that are too big may be impossible to co-ordinate.

Robin Dunbar.an anthropologist at Oxford University,has done a lot of work on primate(灵长目）groups.His argument is that the size of the group is linked to the size of the brain.With their large brains,humans can cope with larger bands,A larger social group has many advantages,allowing for greater protection and specialization.

Whereas 150 is sometimes referred to as the"Dunbar number",the academic himself in fact refers to a range of figures.He observes that humans tend to have five intimate friends,15 or so good friends,around 50 social friends and 150-odd acquaintances.

Running a larger network can be difficult.The armed forces have spent more than 1,000 years experimenting with unit size.A Roman centurion(百天长）oversaw 100.The modern American army company has 180 members.Britain's equivalent numbers 120.These are rough estimates,rather than fixed figures.But it is striking that many group activities seem to be close to a Dunbar number. The Special Air Service of Britain has four-man patrols;when your life depends on it,you need to have absolute trust in your colleagues.As a result,such groups are limited in size.

For much of economic history,work was conducted in small units by peasants,tenant farmers and craftsmen.The coming of powered machinery enabled production at a much larger scale,with workers crowded into factories.These days the rise of the service economy means that workers are no longer concentrated in such large groups.

This may not be a bad thing.It was easy for employees in large factories to regard remote company owners as "them"rather than"us".The modern company may settle on a model with a small group of"core"workers and a larger group of contract workers.The result may be more united within the core staff but the non-core staff may be less well treated.The small core teams may work effectively.The big question will be the effect on morale of those outside those teams.

【1】What does the first paragraph serve as in the whole article?

A.An example of the topic,

B.An introduction to the topic,

C.A guide to the whole article,

D.No relation to the passage at all.

【2】What does the underlined"This"in the last paragraph refer to?

A.Workers crowded into factories

B.'These days the service economy has risen.

C.Workers are no longer concentrated in such large groups.

D.Employees regard company owners as"them"rather than"us".

【3】What is probably the best model for a company according to the author?

A.A large group of exact 150 workers.

B.A small group of less than 15 core workers.

C.A small group of peasants and a large group of factory workers.

D.A small group of efficient workers and more contract workers.

【4】What is the main purpose of writing the text?

A.To offer companies some useful advice.

B.To introduce us the most suitable size of teams.

C.To arouse the readers' interest in Robin Dunbar.

D.To persuade companies to adopt the"Dunbar number".

24、   When Omar Yaghi was growing up in Jordan, his neighborhood received water for only about 5 hours once every 2 weeks. If Yaghi wasn’t up at dawn to turn on the taps to store water, his family, their cow, and their garden had to go without. At a meeting last week, Yaghi, now a chemist at the University of California, reported that he and his colleagues have created a solar-powered device that could provide water for millions in water-stressed regions. At its heart is a porous crystalline  (多孔晶体) material, known as a metal-organic framework (MOF), which acts like a sponge: It sucks water vapor out of air, and then releases it as liquid water.

Yaghi and his colleagues first developed a zirconium( 锆 )-based MOF in 2014 that could harvest and release water. But at $160 per kilogram, zirconium is too expensive for massive use. So, last year, his team came up with an alternative called MOF-303, based on aluminum, which costs just $3 per kilogram, but the harvest was only about 0.2 liters per kilogram of MOF per day.

In July 2019, Yaghi reported that his team has designed a new and far more productive water harvester. Supported by a solar panel to power a fan and heater, which speed the cycles, the new device produces up to 1.3 liters of water per kilogram of MOF per day from desert air. Yaghi expects further improvements to increase that number to 8 to 10 liters per day. And his company plans to release a microwave-size device able to provide up to 8 liters per day this fall. The company promises an enlarged version next year that will produce 22,500 liters per day, enough to supply a small village.

However, it needs to be shown that Yaghi’s MOFs can be produced cheaply on a large scale. Each potential commercial MOF needs to prove itself in stability, efficiency, and life span. But if MOFs can pass those tests, they could offer a solution to some of the world’s most pressing problems.

【1】Why is Omar Yaghi’s childhood mentioned at the beginning?

A.To show how serious water problem is. B.To lead in the topic.

C.To introduce the chemist. D.To arouse reader’s interest.

【2】What is the problem of MOF-303?

A.It costs too much. B.It can’t last long.

C.It is hard to operate. D.It is low in efficiency.

【3】According to Yaghi, how much water will a large water harvester produce per day?

A.1.3 liters. B.10 liters.

C.22,500 liters. D.8 liters.

【4】What can be concluded from the last paragraph?

A.Yaghi’s MOFs are in great demand now.

B.Yaghi’s MOFs may help solve water shortage.

C.Yaghi’s MOFs have already entered the market.

D.Mass production of Yaghi’s MOFs is impossible.
