21、The Damage that aging does to a body extends all the way down to the cellular level. But the damage increased by cells in older muscles is especially severe, because the cells do not reproduce easily and they become weaker as their mitochondria (线粒体), which produce energy, reduce in energy and number. A study, however, suggests that certain sorts of exercise may remove some of what time can do to our mitochondria.
Exercise is good for people, as everyone knows. But scientists have surprisingly little understanding of its cellular impacts and how those might vary by activity and the age of the exerciser. So researchers recently conducted an experiment on the cells of 72 healthy but sedentary (久坐的) men and women who were 30 or younger or older than 64. After baseline measures were established for their aerobic (有氧的) fitness, their blood-sugar levels and the gene activity and mitochondrial health in their muscle cells, the volunteers were randomly assigned to a particular exercise program.
Some of them did intense (强烈的) weight training several times a week; some did brief interval training three times a week on exercise bicycles; some rode exercise bikes at an appropriate pace for 30 minutes a few times a week and lifted weights lightly on other days. A fourth group, the control (对照组), did not exercise. After 12 weeks, the lab tests were repeated. In general, everyone experienced improvements in fitness and an ability to regulate blood sugar.
But more unexpected results were found in the biopsied (活组织检查) muscle cells. Among the younger subjects who went through interval training, the activity levels had changed in 274 genes, compared with 170 genes for those who exercised more appropriately and 74 for the weight lifters. Among the older group, almost 400 genes were working differently now, compared with 33 for the weight lifters and only 19 for the appropriate exercisers.
Many of these affected genes, especially in the cells of the interval trainers, are believed to influence the ability of mitochondria to produce energy for muscle cells; the subjects who did the interval exercise showed an increase in the number and health of their mitochondria — an impact that was particularly pronounced among the older cyclists. It seems exercise could help contain the decline in the cellular health of muscles associated with aging, especially if it was intense, says Dr. Sreekumaran Nair, the study’s senior author. In fact, older people’s cells responded in some ways more strongly to intense exercise than the cells of the young did — suggesting, he says, that it is never too late to benefit from exercise.

22、“I like pigs,” Winston Churchill supposedly once said. “Dogs look up at us, cats look down on us, but pigs treat us as equals.” Whether Churchill’s contemporary George Orwell also liked pigs is less clear. But he, too, surely saw something in them that was lacking in other domestic beasts, for it was they who ended up running the show in novel Animal Farm. Pigs, then, are intelligent social creatures.
And, like all animals, they sometimes fight. A study just published in Animal Cognition by Ivan Norscia, a biological anthropologist at the University of Turin, in Italy, and his colleagues, looked at how a group of 104 domestic pigs went about resolving such incidents. In total, Dr. Norscia and his team studied the details of 216 pig conflicts over the course of six months.
Some pigs tend to be attackers; others tend to be victims. Who is what depends largely on weight, for, among pigs pounds mean power. The attacker might bite, kick, bump or lift the victim (or string together a sequence of those actions). Most conflicts ended in seconds, but some lasted a minute or two.
In most animal species that would be that. However, many of the pig conflicts Dr. Norscia observed had interested parties beyond the protagonists (主角). He therefore wanted to understand the role of these bystanders in resolving fights —and what this says about pigs’ cognitive (认知) abilities.
Since there was usually not enough time for a bystander pig to intervene during the heat of a conflict (though this did occur), he and his colleagues looked at what happened in the three minutes directly following an aggressive interaction. Sometimes, they found, the protagonists made up on their own —for instance, by touching noses.
On other occasions, though, a third pig stepped in. Sometimes this bystander acted as a peacemaker, engaging with the attacker and reducing the number of subsequent attacks compared with what might otherwise have been expected. Sometimes, by contrast, the bystander engaged with the victim. This appeared to calm the victim down, for it reduced anxiety-related behavior such as shaking and scratching.
【1】Why does the author mention Winston Churchill in the first paragraph?
A.To prove pigs are clever.
B.To show pigs are inspirational.
C.To state Churchill loves pigs.
D.To introduce the topic of the text.
【2】What probably decides on the pigs’ roles in pig conflict?
A.Their ages.
B.Their weight.
C.Their safety needs.
D.Their cognitive abilities.
【3】Why did Ivan Norscia and his colleagues conduct the study?
A.To comprehend the role of bystanders in conflict resolution.
B.To figure out the relationship between pigs.
C.To record the details of 216 pig conflicts.
D.To find out the reason for pigs’ conflicts.
【4】How will the bystander interact with the victim after a fight?
A.By shaking it.
B.By touching its nose.
C.By scratching its back.
D.By offering comfort to it.
23、One late winter day in Manchester, UK, as I step inside the University of Salford’s latest research building, the cold 3°C air bites immediately. In fact, it’s a giant climate- controlled room, designed to test how homes built today will cope with the wilder weather climate change could bring.
Inside the £16-million room, researchers can create any weather they want with the touch of a button, from —20°C cold to 40°C heatwaves, alongside strong winds, snow and ice. KAnywhere people live, we can recreate those conditions,,, says Fitton, who leads the Energy House 2.0 project for the university.
Inside the building are two new-build homes, complete with brickwork and pot plants. Both are equipped with cutting-edge green technology) like electric vehicle charging points, and will act as test beds to build greener homes in the UK. In 2025, the Future Homes Standard(FHS) will require all new homes to be built without gas central heating and with other green measures. Homes built to the FHS must deliver a 75% to 80% reduction in carbon emissions compared with homes built today.
That is why Bellway, partnering with the project, has built the rooms from its Coppersmith range of homes inside the Energy House 2.0. Yet clearly this is no ordinary new-build. For one thing, packed inside are three different heating systems: two air source heat pumps? plus panel heaters dotted around the walls and ceilings. There’s also a solar power input, a battery and a smart hot water tank that heats water using solar generation.
Over the coming months, Bellway will test different combinations of these technologies to find the most cost-effective way of meeting the FHS regulations.
Financially, things are promising: Based on energy-performance calculations, Bellway says its Future Home could have energy bills of just £11 a year.
Energy House 2.0 will let researchers see how houses perform in the UK’s future climate. “We can cycle through the climate change predictions 50 years into the future and see if we have any problems says Fitton.”
【1】What’s the aim of building the £16-million room?
A.To predict the extreme weather humans will face.
B.To test how long a house stands in extreme weather.
C.To find a way for homes to deal with climate change.
D.To explore the most habitable homes for humans.
【2】Why does Bellway cooperate with the project?
A.To design green houses to meet the standards of FHS.
B.To explore the household use of advanced technology.
C.To sponsor the Energy House 2.0 for market profit.
D.To popularize its Coppersmith range of future homes.
【3】Where will Energy House 2.0 research go?
A.It’ll explore the use of cutting-edge technology.
B.It’ll find how houses tackle future climate changes.
C.It’ll make future houses have zero carbon emission.
D.It5ll spread Coppersmith range all over the country.
【4】What is a suitable title for the text?

26、阅读下面材料,根据其内容和所给段落开头语续写两段,使之构成一篇完整的短文。
There was once a boy in ragged clothes running to ask a building contractor(包工头)who wore elegant clothes in a construction site of a skyscraper(摩天大楼),“How could I become as rich as you when I grow up?"
With a glance at the boy,the tall and strong-build contractor replied,"I would like to tell you a story first about three diggers.The first digger liked holding a spade(锹) without doing anything but saying that he wanted to be a boss in the future.The second digger liked complaining about the long-time work and his low salary.The third digger always quietly devoted himself to digging without making any claims.Several years later, the first digger was still holding his spade in the original place and the second took an excuse of work injury for early retirement.Only the third digger became the boss of the building company.Do you understand the moral of this story?Just go to buy a red shirt and work hard.”
The little boy was puzzled and could not figure out the implication of the story.So he asked the contractor to explain further.Pointing to the builders who were working on the scaffold(脚手架),the contractor talked to the little boy,"Look at those people! They are all my workers.I can't remember all of their names,and even I have no impression of some of them.But if you look carefully,you will notice a sunburned man in red among them.I notice him very early.He seems to be working harder with higher spirits than others.He is always the first one to work every day while the last one to leave.It is exactly his red shirt that makes him stand out among all the workers.Now I am about to ask him to be my taskmaster and I believe he will work even much harder from now on.Maybe he will soon be promoted to my assistant."
注意:1.续写词数应为150左右;
