In the movie The Wrong Trousers, a pair of futuristic trousers lets people walk on walls and ceilings.Inspired by the movie, researchers in England created “The Right Trousers”, a set of trousers embedded(嵌入) with electrical pumps to force air into tiny tubes that expand and can help elderly or disabled people with issues like getting up or improving blood flow.Now, material scientists, computer programmers and fabric designers are working to advance robotic clothing.
In June, researchers in Australia created robotic fibers, which can make fabric move automatically.Last year, scientists at MIT built fiber batteries that could be embedded into clothes and power robotic clothing.In recent years, Google partnered with brands like Levi's and Adidas to put sensors in jackets, backpacks and shoes, letting users access their phones instantly.Researchers said they could soon unlock an era where clothing will act more like a computer, sensing how your body feels and telling your clothes how to help.
At the University of New South Wales in Australia, researchers are creating fabrics that can shape-shift.Thanh Nho Do, a senior lecturer at the school, said his team has created tiny tubes that can weave into sheets of fabric.These tubes can make fabric take various preprogrammed shapes.But challenges still remain for Do's team, notably around making these robotic tubes smaller so they can weave easily with other fabrics.
Rebecca Kramer Bottiglio from Yale University agreed that many challenges remain before smart clothing “reaches their full potential”. “It will be challenging to make these clothes, equipped with fibers and technology, strong enough to go through multiple cycles in the laundry,” she said.Despite that, she says researchers will figure out a way forward.“Recent breakthroughs point toward a not-so-distant future where smart clothing will be a part of our everyday life,” she said.

We know light pollution can threaten the heath and well-being of humans, animals, and the environment.Researchers have long studied the impact on birds and how brightness can affect their reproduction(繁殖), feeding, and migration behaviors.A new study, published in Nature, takes a comprehensive look at how light pollution affects birds throughout North America.It found that these factors can affect how birds succeed in reproduction and often are related to the impacts of climate change.
For the study, researchers looked at data collected by other researchers and by citizen scientists.They analyzed how light pollution affected the reproductive success of more than 5,800 nests from 142 bird species across North America.They considered several factors including the time of year when reproduction happened and whether at least one chick got the feathers necessary for flight or independent activity.
Birds typically reproduce about the same time each year, using daylight cues to time their reproduction to coincide with when the most food will be available to feed their babies.“Artificially changing day length with light pollution essentially misleads them to start reproducing earlier than they normally would,” Francis says.When that happens, sometimes chicks hatch before food is available.But with climate change, sometimes the results are a little different.
“We also found that the same species that reproduce earlier appear to benefit from light exposure in terms of nest success.This was unexpected.We do not know for sure that light pollution helps birds cope with climate change.It needs to be tested in further research.Nevertheless, it is quite possible that light allows birds to ‘catch up’ to earlier prey availability due to climate change,” Francis explains.
Researchers know through studies of climate change that plants and insects are starting to emerge earlier each spring.They respond to warmer temperatures rather than light.So possibly the birds are benefiting from that change. “A likely explanation is that light pollution causes birds to nest earlier and restore the match between the timing of their nesting and the highest availability of their food,” Francis says. “Again, this needs to be tested.Still, if true, it means that birds exposed to light pollution are ‘keeping up’ with climate change and those in pristine areas where there is no light pollution would not.”

语篇导读 主题语境:人与社会/历史、社会与文化。本文为说明文,介绍了位于中国湖南省的武陵源风景名胜区。
1.答案 an
解析 考查冠词。句意:武陵源风景名胜区位于中国中部的湖南省,面积超过397平方公里。with an area of…面积有……,为固定搭配,area的发音为元音音素开头,故此处应用不定冠词an,表示泛指。
2.答案 includes
解析 考查时态和主谓一致。句意:它包括三个部分:张家界国家森林保护区、索溪峪地区和天子山地区。句子陈述的是客观事实,应用一般现在时;主语为It,故填includes。
3.答案 developing
解析 考查非谓语动词。句意:主要地貌由砂岩丘陵组成,逐渐发展成3 103多座惊人的山峰,其中许多超过400米高。句中有谓语动词consists of,且空前无连词连接,故空处应用非谓语动词,句中表示自然而然的结果,故用现在分词作结果状语。
4.答案 which
解析 考查引导词。句子为非限制性定语从句,先行词为peaks,指物,在从句中作of的宾语,故用关系代词which引导。
5.答案 from
解析 考查介词。句意:该遗址远离现代城市,85%被树木覆盖。(be) remote from…远离……,为固定搭配。
6.答案 wonders
解析 考查名词的数。句意:武陵源以五大奇观而闻名:壮丽的山峰、独特的岩石、宁静的山谷、静水和深邃的洞穴。wonder(奇观)为可数名词,根据five可知,空处应用名词复数形式。
7.答案 was listed
解析 考查时态、语态和主谓一致。句意:它在1992年被联合国教科文组织列为世界自然遗产。句子陈述的是过去发生的事,It指代上文的The Wulingyuan,与list之间为逻辑上的动宾关系,故句子应用一般过去时的被动语态;主语为it,故填was listed。
8.答案 constantly
解析 考查词性转换。句意:随着季节和天气的变化,它们不断向游客呈现不同的景观。空处作状语修饰动词present,应用副词形式。constantly不断地。
9.答案 highest
解析 考查比较等级。句意:该地区最高的山峰之一是兔儿望月,又叫赏月兔峰,天子山因其良好的景观而被特别推荐。“one of the+形容词最高级+可数名词复数”意为“最……的……之一”,为固定句式。
10.答案 its
