We may not be aware of it, but ordinary family homes in the U.S. and the rest of the world are not energy-efficient.

Most of their energy goes to heating and cooling, and a lot of it is wasted, as warm air and cool air escape through fireplace chimneys and thin or poorly fitting windows and doors. A passive house loses almost none."Imagine a thermos(保温瓶),"said housing developer Brendan O’Neill."You have insulation(隔绝) everywhere, and it’s basically completely sealed. And so the idea is to build a house like a thermos. So the windows are sealed. There’s insulation completely surrounding the building. We make it as sealed as possible."

A 147-square-meter passive house, presented by O’Neill Development Corp. as a demonstration unit just outside Washington, was brought to the site in two boxes. "Once it’s set and put together, it takes about four weeks to complete the outside construction, to put down carpets," O’Neill said. "If everything is set in place, you put a house like this together in about four months.”The total cost of building it was $325,000, or about 17 percent more than constructing an ordinary house. But its utility(公用事业) bill is only around $20 monthly, or one-tenth the amount for the average house of the same size.

While passive houses have been around for a long time, the idea has never taken root in the U.S. There was no driving force to push it.

However, David Peabody, an architect who designs passive houses said, "I think climate change is now becoming a larger issue. And I think building standards are catching on to that. So people are becoming more aware of energy."Peabody said the cost of building passive houses could come down."What really makes sense for truly affordable housing," he said, "is to build multi-storey buildings."

1.Why aren’t ordinary family homes energy-efficient?

A. Building them wastes much energy.

B. Their energy mainly goes to heating and cooling.

C. Their sealing performance is poor.

D. They have no insulation around at all.

2.What is the feature of a passive house?

A. There’re no windows or chimneys.

B. There’s little space to place furniture.

C. Its building cost is relatively high.

D. It takes about four weeks to build one.

3.What’s David Peabody’s attitude to the future of the passive house?

A. Cautious.        B. Optimistic.        C. Skeptical.        D. Concerned.

Dolphin or not a dolphin? That is the question! You see，there are several types of dolphins．Some are saltwater dolphins while others are river dolphins．

“What are the 32 types of dolphins?”When people are asking the question，they are actually referring to the saltwater dolphins in oceans and seas．The river dolphins living in fresh water are not included in these species．But what would be the answer in this case if we ask．“Dolphin or not a dolphin?”The answer would obviously be yes．River dolphins still belong to the dolphin family．

Among the 32 types of dolphins do not actually wear the word“dolphin”in their names，such as the tucuxi，while others actually have the word“whale”as part of their names even if they are not whales but in fact，belong to the dolphin family，for example，the melon-headed whale and the killer whale．So what would be the answer to the question“Dolphin or not a dolphin?”in these cases? It would’be yes．All these species do belong to the dolphin family．

Another question that people ask is．“Are the sea animals that perform at aquariums(水族馆)all dolphins?”So，it always seems to come back to the question，“Dolphin or not a dolphin?”Well the answer is no in this case．The sea animals that perform there are not all dolphins．The beluga which people tend to think belong to the dolphin family because they show what seems like a smile，like most dolphins，are in fact a species of the whale family．

Now that you read these facts about dolphins，you probably realize that certain sea animals may appear to be part of the dolphin species and that others seem to be part of the whale family but in either case，it is not obvious and can be surprising when you identify a sea animal as being a dolphin or not a dolphin．That is the question ！

1.Which of the following statements about dolphins is RIGHT according to the passage?

A. The tucuxi is a type of dolphin living in rivers．

B. There are 32 types of dolphins in the world altogether．

C. All the sea animals that perfom at aquariums are dolphins．

D. The melon-headed whale and the killer whale actually belong to the dolphin family．

2.What do we know about the majority of the dolphins?

A. They appear friendly．　　 B. They perform for audience．

C. They look like whales．　　 D. They live in fresh water．

3.What could be added about dolphins before the last paragraph if you were the author?

A. The living areas of dolphins．

B. Training of dolphins at aquariums．

C. The eating habits of dolphins．

If you are a sleep deprived(被剥夺) teacher, you may not be aware of the term woodpeckering(啄木鸟式点头), but you’ve probably done it. It happens the day following a bad night’s sleep. You’re sitting in a long meeting and you can barely keep your eyes open, so you support your head up with your hand. Next thing you know, you are moving your sleeping head back to its upright position. Do this a few times and you are woodpeckering.

I thought I knew sleep deprivation when I did my medical internship(实习) in hospital. That year I frequently went 36 hours with no sleep. When I finished my stay in neurology(神经内科), I welcomed the promise of full nights of sleep ever after. It went pretty well for the next 10 years until I became a school teacher and experienced a whole new level of sleep deprivation.

Teachers’ working hours go far beyond the 8 am to 5 pm schedule of kids in school. There are hours spent at staff meetings, correcting homework, preparing for the next day- and then there is the worrying. What I did in a hospital emergency room required no more intensive mental energy than what is need to keep 30 kids attentive enough to learn what I was teacher.

Good teachers are like magicians keeping a dozen balls in the air to come at right time, with alarm set for 6 am to finish grading papers, memories of the day that’s gone- including the students who didn’t understand something, forgot their lunch or were embarrassed by wrong answers. All these will become sleep-resistant barriers. And also with some financial stress, you’ll have a cycle of insomnia(失眠) with unwelcome consequences.

With inadequate sleep comes irritability(易怒), forgetfulness, lower tolerance of even minor annoyances, and less efficient organization and planning. These are the very mental useless that teachers need to meet the challenges of the next day. In wanting to do a better job the next day, the brain keeps bringing up the worries that deny the rest it needs.

1.After a bad night’s sleep, usually the direct effect for the next day is to ______.

A. keep one’s eyes open all the time

B. move head back and forth

C. raise one’s head in upright position

D. keep nodding like a woodpecker

2.The writer’s new level of sleep deprivation began since he _____.

A. did his medical internship in hospital

B. began to teach in a school

C. left hospital ten years ago

D. went 36 hours with no sleep

3.From paragraph 3 we can infer that ____.

A. teachers’ work is comfortable

B. correcting homework needs less time

C. working in hospital is even tougher

D. teaching needs more mental energy

4.Good teachers’ sleep problems are mainly due to the _____.

A. common sleep-resistant barriers

B. embarrassment for wrong answers

C. diligence and devotion to teaching

D. misunderstanding of their students

5.What does the writer really want to tell us in the last paragraph?

A. Unfavorable effects of inadequate sleep are various

B. Lay down worries and sleep well first for the next day.

C. Teachers should often practice mental muscles.

D. Better job has nothing to do with inadequate sleep.
