21、Lights Out at Bedtime
There are plenty of good reasons to power up a personal desktop or laptop computer in the evening — writing e-mails， chatting on social networks or making purchases over the Internet， for instance． But various studies indicate that people who stare at a PC’s bright monitor shortly before going to bed probably sleep less soundly than they would otherwise because the light seriously affects their natural wake-sleep cycle．"They haven't proved it though，" says Dieter Kunz， the team's director at Charite's Psychiatric Clinic in St． Hedwig's Hospital in Berlin．
Similarly， exposure to just 10 minutes of normal bathroom lighting is enough to free the sleep hormone melatonin， which regulates people's natural wake-sleep cycle and makes them sleepy at nightfall．
Ten years ago， a team of British and American researchers detected a photo-pigment（光敏色素） in the human eye that signals to the body whether it is day or night， summer or winter． The photo-pigment is especially sensitive to blue light．
"The blue light more or less tells the body， It's daytime， be awake，'" Kunz says． Monitors have a mostly cold white light content and scientists suspect the photo-pigment may react similarly to it． So the longer people look into the bright light， the more awake they become - and then sleep poorly．
A lot of people have difficulty "switching off" in the evening． About half of the women in Germany and a quarter of the men sleep poorly．
Environmental factors are only one of the possible causes． Job stress as well as personal and health concerns are also the main reasons for their sleep problems．
In addition， electronic objects' standby lights and indicator lamps can be annoying in the dark and affect sleep．"Sound scientific evidence is still lacking on this matter，" Kunz notes．
According to Kunz， those who cannot go without their computer in the evening should turn down the blue content if possible and lower the brightness somewhat．"But nobody does that because， after all， you want to concentrate while working at the computer and the light helps the brain．"
【1】The passage is mainly about ____________．
A. natural wake-up cycles
B. the effect of light on sleep
C. personal and health concerns
D. functions of computer monitors
【2】The underlined word “which” in Paragraph 2 refers to_____．
A. normal bathroom lighting
B. 10-minute exposure to lighting
C. the release process of a chemical
D. a chemical affecting one’s sleep cycle
【3】We can learn from the passage that ______．
A. the blue light has a calming effect．
B. the photo-pigment tells people day or night
C. women in Germany use computers more often than men
D. it has been proved that standby lights affect people’s sleep
22、Thermoelectric generators turn waste heat into electricity without producing greenhouse gas emissions, like a free lunch. But the high cost of these devices has prevented their widespread use. Now, researchers have found a way to make cheap thermae-lectrices that work just as well. The work could pave the way for greener car engines, and other energy-generating devices.
“This looks like a very smart way to realize high performance,” says Li-Dong Zhao, a materials scientist. He notes there are still a few more steps before these materials can become high-performing. However, he says, “This will be used in the not too far future.”
Thermoelectrics are semiconductor devices placed on a hot surface. That gives them a hot side and a cool side. If a device allows the hot side to warm up the cool side, the electricity stops flowing. A device’s success at preventing this, as well as its ability to conduct electrons, feeds into a score known as the figure of merit, or ZT.
Researchers have produced thermoelectric materials with increasing ZTs. The record came in 2014 when Mercouri Kanatzidis came up with a tin selenide with a ZT of 3.1. Yet the material was too fragile to work with. “For practical applications, it’s a non-star-ter,” Kanatzidis says.
Getting through that door will still take some time. The tin selenide the team makes is mixed with Na, creating a “p-type” material that conducts positive charges. To make working devices, researchers also need an “n-type” version to conduct negative charges.
Zhao’s team is now working on making an n-type version. Once successful, researchers should have a clear path to making a new generation of super-efficient thermoelectric genera-tors. Those could be installed everywhere from automobile exhaust pipes to water heaters and industrial smelters to scavenge some of the 65% of fossil fuel energy that winds up as waste heat.
【1】The first paragraph wants to tell us________.
A．The wide use of thermoelectric generators
B．The devices of current thermoelectric generators
C．The reason why researchers make cheap thermoelectrics
D．The greener car engines that contribute to environmental protection
【2】How does Li-Dong Zhao feel about cheap thermoelectric generators?
A．Indifferent.
B．Optimistic.
C．Critical.
D．Worried.
【3】What do you know about the research in 2014 from paragraph 4 and 5?
A．It was far from a success for practical applications.
B．A tin selenide with a ZT of 3.1 can be easy to work with.
C．Researchers made an “n-type” version to make working devices
D．A “p-type” material made from the tin selenide conducts negative charges
【4】What does the underlined word “scavenge” in the last paragraph mean?
A．Recycle.
B．Produce.
C．Clean.
D．Increase.

24、Britain’s meat industry on Friday warned that an upcoming shortage of carbon dioxide (CO2) could cause massive disruption (中断) to food supplies within two weeks.
The gas is used to stun animals before slaughter (屠宰), in the vacuum packing of food products to extend their shelf life, and to put the fizz into beer, cider and soft drinks. It is also required for some medical procedures and used in the nuclear and semi-conductor industries.
Britain’s food supply chain, already creaking from a severe shortage of heavy goods vehicles (HGV) drivers and the impact of Brexit (脱欧) and COVID-19, is heavily reliant on fertiliser producers for CO2 which is a by-product of their production process. However, two of the largest fertiliser producers, Norway’s Yara YAR.OL and rival CF Industries Holdings CF.N, have restrained production due to a sudden increase in natural gas prices, which has in turn started to dry up CO2 supplies.
Nick Allen, chief executive of the British Meat Processors Association (BMPA), said that once current stocks of the gas run out, some meat companies will have to stop taking animals and close production lines, leading to a logjam of animals back to the farms. “We already have this situation in the pig industry which is now facing the disruption prospect of a humane killing on farms,” he said. The BMPA is persuading Business Minister Kwasi Kwarteng to help support UK CO2 production in the short-term.
“We are monitoring this situation closely and are in regular contact with the food and farming organizations and industry, to help them manage the current situation,” said a UK government spokesperson. “The UK benefits from having access to highly diverse sources of gas supply to ensure households, businesses and heavy industry get the energy they need at a fair price. Britain last suffered a major CO2 shortage in 2018, leading to some drinks wholesalers to ration (定量) sales.”
【1】What’s the direct cause of the CO2 shortage this year?
A．A government policy.
B．Cost rise.
C．Transportation failure.
D．An infectious disease.
【2】What does the underlined word “logjam” mean in paragraph 4?
A．Recovery.
B．Promise.
C．Death.
D．Bottleneck.
【3】What measure may the UK government take?
A．To explore more gas supplies.
B．To stop marketing animals.
C．To limit the drinks wholesale.
D．To close production lines.
【4】What may be the suitable title for the passage?
A．Diverse Applications of CO2
B．The Future of Britain’s Meat Industry
C．Efforts Taken to Produce CO2
D．CO2 Shortage Hit Food Supplies
