Imagine a house that keeps itself warm in the wintertime. Think of the savings in terms of fuel bills and unfriendly emissions. Such houses in fact exist, called “passive houses”. The concept of these highly energy-efficient buildings took root in the 1990s, before slowly consolidating as a niche construction (生态位构建) concept in the 2000s. Are passive houses now actively moving into the mainstream as sustainable buildings?

For Brian Mc Garry, an economics lecturer who built a family house based on passive housing criteria in the Pyrenees this year, the arguments look convincing. As his first full winter in the low energy house draws in, we asked him to keep us informed. Do passive houses work?

I had never heard of a passive house in February 2012, when I purchased a plot of land. Nor did I expect that I would be persuaded to build a pre-constructed, custom-designed house based on energy-efficient passive house criteria. It promised to be easier and quicker to build, cheaper to run, and more comfortable to live in. The objective was to incorporate the fundamental concepts of passive energy management into my project: an airtight and highly insulated building envelope; large south facing double or triple-glazed windows (if possible, filled with argon gas) that passively capture the energy of the sun; a heat recovery ventilation system to provide fresh air; and a simple, low-cost heating system consisting of a modern wood-burning stove, a bathroom heater and a portable radiator backup for when the sun doesn’t shine and temperatures decline. No significant limitations were placed on the design, and it had excellent environmental credentials. Moreover, the cost was no more than a conventional build.

After six months in use, the house is proving to be both cheap to run and remarkably comfortable–staying cool in the hot summer was effortless, as long as the windows were shuttered or shaded from the sun. Nowstaying warm in the cold, high-altitude December climate also seems easy, so far.

Winter arrived in force in the Pyrenees in November, with abundant snowfalls and temperatures as low as minus 8° Celsius. Though early days, the house has responded well: the stove is lit during cold evenings but the portable radiator has not yet been needed. This type of construction seems not only to make economic and environmental sense, but to enhance our quality of life, too.

Published March 30, 2011)Albert Einstein’s Theory of Relativity might have a few mistakes—and Jake Barnett has set out to prove it.Between attending college classes at Indiana University-Purdue University Indianapolis (IUPUI) and tutoring his fellow students, Jake is also working on a new theory about the creation of the universe.He happens to be 12 years old.

From an early age, Jake showed an extraordinary interest in stars.When he was 3, his parents took him to a space observatory.He tried to learn as much as he could about astronomy.Jake’s IQ measured remarkably high at 170.

As a baby, Jake was found out with Asperser’s syndrome, a form of autism (孤独症).Autism causes difficulties in communication and social abilities.People with autism may also have strong interests—like Jake’s interest in the stars at a young age.

The symptoms of autism can range from mild to extremely severe.Asperser’s is one of the milder forms of autism.Sometimes people with Asperser’s, like Jake, develop extremely advanced skills in science, music or art.

When Jake was in elementary school, his parents worried that the effects of his Asperser’s were worsening.He became quiet.And he was withdrawing from people.So a doctor recommended that Jake’s parents let him study more advanced subjects, like math and physics.

Jake’s mother asked an astronomy professor to let Jake sit in on his class.Now, Jake studies advanced sciences like electromagnetic physics at IUPUI.

But Jake thinks it’s important to have a normal life too.He likes to play Guitar Hero with his friends and watch science fiction movies.He also enjoys playing classical music on the piano.But for Jake, studying physics is the most important thing.Jake’s professor, John Ross, is working on getting a large sum of money for him to do research at the university.

Doctors have said Jake’s autism symptoms have lessened over time.Still, Jake proudly refers to himself as an “Aspy”, or someone with Asperser’s.In an interview with his university student newspaper, he said, “I think the autism is the reason I’m even at IUPUI.”

1.What did Jake want to do at IUPUI?

A. Get a degree in astronomy.

B. Put forward his own theory in physics.

C. Become an Albert Einstein in the future.

D. Teach his fellow students Theory of Relativity.

2.Which of the following is the correct order of the events that happened to Jake?

a. He set out to disprove Einstein’s theory.

b. He began to study math and physics.

d. He was found out with a mild form of autism.

A. b-d-c-a

B. d-b-c-a

C. b-a-c-d

D. d-c-b-a

3.The underlined sentence in the passage means ______.

A. he was unable to help others

B. he was impolite to other people

C. he was afraid of seeing other people

D. he was only concerned about learning

4.In the eyes of Jake, autism is something ______.

A. not worth worrying about

B. annoying

C. not necessary to know about

D. embarrassing
