21、Sending human travelers to Mars would require scientists and engineers to overcome a range of technological and safety obstacles. One of them is the enormous risk posed by particle radiation from the sun, distant stars and galaxies.
Answering two key questions would go a long way toward overcoming that: Would particle radiation pose too serious a threat to human life throughout a round trip to the red planet? And, could the very timing of a mission to Mars help protect astronauts from the radiation?
In a new article published in the journal Space Weather, an international team of space scientists with researchers from UCLA, answers those two questions.
That is, humans should be able to safely travel to and from Mars, provided that the spacecraft has adequate shielding (防护) and the round trip is shorter than approximately four years. And the timing of a human mission to Mars would indeed make a difference: The scientists determined that the best time for a flight to leave Earth would be when solar activity is at its peak, because the most dangerous and energetic particles from distant galaxies are deflected (偏移) during solar maximum.
Imaginably, the average flight to Mars takes about nine months, so it is reasonable that a human mission could reach the planet and return to Earth in less than two years,according to Yuri Shprits, a UCLA research geophysicist and co-author of the paper.:
“This study shows that although space radiation imposes (追使) strict limitations on how heavy the spacecraft can be and the time of launch, and it presents technological difficulties for human missions to Mars, such a mission is viable,” said Shprits, who also is head of space physics and space weather at GFZ Research Centre for Geosciences in Potsdam,Germany.
【1】What are the two questions about?
A．Getting rid of the technological obstacles.
B．Making astronauts return from Mars safely.
C．Protecting astronauts from particle radiation.
D．Launching the spacecraft to Mars in shielding.
【2】Which decides the time when humans fly to Mars?
A．The distance to stars.
B．The length of the round trip.
C．The size of particles.
D．The degree of solar activity.
【3】What does the underlined word “viable” in Paragraph 6 mean?
A．Challenging.
B．Workable.
C．Rewarding.
D．Affordable.
【4】What is the best title for the passage?
A．Two Questions, a Help to Humans?
B．Particle Radiation, an Obstacle to Mars?
C．Travelling to Mars, an Impossible Mission?
D．A Round Trip to Mars, Technological Advance?
22、Picture this:you’re switching channels and you come across an advertisement for a popular cigarette brand with doctors promoting its health benefits. Unbelievable? Think again. A century ago, attitudes around smoking were strikingly different, and, shocking though it may now be, it was common to see health professionals give their approval to cigarette makers.
In a jaw-dropping state of affairs , doctors weren’t the only ones to promote smoking —in fact , during the first run of the cartoon show The Flintstones in 1960, its official sponsor was Winston cigarettes, and in one advertising session, the characters Fred Flintstone and Barney Rubble are seen smoking a pack together, with the latter remarking:“It tastes good, like a cigarette should.”
There was pushback in the media against the overstatements of wealthy tobacco giants (巨头) however,and it was the American issue of Reader’s Digest which regularly sounded the smoke alarm.The first story on the topic was published in its pages in 1924.“Does Tobacco Injure the Human Body?”, focused on a groundbreaking study that concluded smoking was “one of the very significant reasons fewer men than women attain old age. ”Another story published in 1952 called “Cancer by the Carton” was credited with contributing to the largest drop in cigarette smoking since the Great Depression.
Smoking has lost its cool factor in recent decades, and the number of smokers across the country continues to steadily decline. In 1922 over 65,000 tons of tobacco were sold in the UK , reaching a peak of 125,960 tons sold in 1961. Due to growing public awareness of smoking’ s harmful health effects, by 2014 that figure had dropped to 43,793 tons.
In the past decade, the rate of smokers has dropped considerably. And it’s young people in particular who are turning away from smoking: 25.7 percent of 18-24 year olds smoked regularly in 2011 while in 2018 16.8 per cent did. Hear that? It’ s the collective sound of lungs breathing again.
【1】What can be inferred from Paragraph 1?
A．Doctors consider smoking harmful to health.
B．People’s attitudes to smoking remain the same.
C．Advertisements for tobacco are everywhere on TV.
D．Cigarette producers disagreed with health proessionals.
【2】What did the stories in Reader’ s Digest reveal?
A．Smoking made profits for tobacco giants.
B．Smoking contributed to the Great Depression.
C．Smoking led to a shorter life of men than women.
D．Smoking caused damage to people’s mental health.
【3】What is the author’ s atitude to the reduction of smoking?
A．Objective.
B．Doubful.
C．Negative.
D．Favorable.
【4】Which of the following can be the best title for the text?
A．The harnful effects of smoking
B．The ups and downs of tbacco industry
C．The change of attitudes towards tobacco
D．The increasing awareness of quitting smoking
23、For humans, the early days of the COVID-19 pandemic were a stressful time, marked by fear, isolation(隔离), canceled plans and uncertainty. But for birds that inhabit developed areas of the Pacific Northwest, the reduction in noise due to pandemic lock downs allowed them to use a wider range of habitats in cities.
A new University of Washington study led by Olivia Sander foot reported that many birds were just as likely to be found in highly developed urban areas as they were in less-developed green spaces during the peak of the COVID-19 lock downs.
“Our findings suggest that some birds may have been able to use more spaces in cities because our human footprint was a little lighter,” said Sander foot. “For about half of the species we observed, neither land use nor canopy cover(林冠盖度)had an effect on their site use. That’s very interesting, because we had expected that whether a habitat was mostly covered in concrete or vegetation could tell us something about what birds would be there.”
In the spring of 2020, Sander foot and her colleagues invited more than 900 community scientists in the Pacific Northwest to participate in the study. The volunteers chose their own monitoring sites—mostly backyards and parks where they could safely follow public health orders—and recorded the birds they observed over a 10-minute period at least once a week.
In order to compare the volunteers’ bird observations with human activity, Sander foot and her colleagues used data from Google’s Community Mobility Reports, which track the relative amount of people moving around at various points during the pandemic. While most people spent the spring of 2020 isolated in their homes, many began venturing out again over the course of the study period.
As people returned to public spaces and human activity increased, the study volunteers recorded an increase in sightings of several bird species in their monitoring sites.
“The birds mostly were in highly developed urban areas at the height of the lock downs, because human activity wasn’t as much of a disturbance, but then returned to those vegetated areas as human activity increased again,” Sander foot said.
【1】What benefit could birds get during the pandemic lock downs?
A．Gaining more human attention.
B．Living in a lively environment.
C．Expanding their living places.
D．Returning to vegetated areas.
【2】What can we learn from Sander foot’s words in paragraph 3?
A．Birds actually dislike living in big cities.
B．It is very difficult to identify bird species.
C．The findings aren’t what he expected.
D．Human footprint hardly affects bird species.
【3】What did Sander foot and her colleagues do for their study?
A．They got community scientists involved in it.
B．They tracked human activity for a whole year.
C．They chose monitoring sites for the volunteers.
D．They only observed birds in less-developed areas.
【4】What can be a suitable title for the text?
A．The Influence of the Pandemic on Humans
B．The Impact of Human Activity on Green Spaces
C．How Birds Adapt Themselves to Uncertainty
D．Birds’ Habitat Change During the Pandemic
24、 Brecon Beacons YAC has an amazing opportunity for budding(崭露头角的) archaeologists of all ages, in Sunderland in Tyne and Wear. Thanks to funding from the Heritage Lottery Fund, professional archaeologists from Wardell Armstrong will be investigating an archaeological mystery and they need your help.
Romans?
“The site is a bit of a mystery”, Frank Giecco from Wardell Armstrong said. “There is a very nice cropmark recorded on the site that has got lots of people very excited. Geophysicists failed to find anything relating to the cropmark. There is anecdotal evidence of Roman material being found, but nothing is officially recorded. We hope to finally answer the question of what is in this field, during the two weeks on site. Is there evidence of any Roman occupation on the site? Can you help us find out?”
Get involved
This is an opportunity for both adults and children to take part in field walking and trial trenching (small hand-dug test pits for children). No experience is necessary, training will be provided by the professional archaeologists from Wardell Armstrong, and all equipment will be provided. Volunteers can attend for as few or as many days as they wish, but they do need to book a place.
