Word Bank 1W hen we think of green buildings, we tend to think of new ones –the kind of high-tech, solar-paneled masterpieces that make the covers of architecture magazines. But the U.S. has more than 100 million existing homes, and it would be 47 wasteful to tear them all down and48 t hem with greener versions. An enormous amount of energy and resources went into the construction of those houses. And it would take an average of 65 years for the49 carbon emissions from a new energy-efficient home to make up for the resources lost by destroying an old one. So in the broadest50 , the greenest home is the one that has already been built. But at the same time, nearly half of U. S. carbon emissions come from heating, cooling and51 our homes, offices and other buildings. "Y ou can't deal with climate change without dealing with existing buildings," says Richard Moe, the president of the National Trust.With some52 , the oldest homes tend to be the least energy-efficient. Houses built before 1939 use about 50% more energy per square foot than those built after 2000, mainly due to the tiny cracks and gaps that 53 over time and let in more outside air. Fortunately, there are a54 number of relatively simple changes that can green older homes, from 55 ones like Lincoln's Cottage to your own postwar home. And efficiency upgrades (升级) can save more than just the earth; they can help56 property owners from rising power costs.A) accommodations I) protectB) clumsy J) reducedC) doubtfully K) replaceD) exceptions L) senseE) expand M) shiftedF) historic N) supplyingG) incredibly O) vastH) poweringWord Bank 2For many environmentalists, the world seems to be getting worse. They have developed a hit-list of our main fears: natural resources are 47 out; the population is ever growing, leaving less and less to eat; species are becoming 48 in vast numbers, and the planet's air and water are becoming ever more polluted.But a quick look at the facts shows a different picture. First, energy and other natural resources have become more 49 not less so, since the book ‘The Limits to Growth' was published in 1972 by a group of scientists. Second, more food is now produced per 50 of the world's population than at any time in history. Fewer people are 51 . Third, although species are indeed becoming extinct, only about 0.7% of them are expected to disappear in the next 50 years, not25~50%, as has so often been 52 . And finally, most forms of environmental pollution either appear to have been 53 , or are transient - associated with the early stages of industrialization and therefore best cured not by restricting economic growth, but by 54 it. One form of pollution - the release of greenhouse gases that causes global warming - does appear to be a phenomenon that isgoing to extend well into our future, but its total impact is unlikely to 55 a devastating (令人心神不安的) problem. A bigger problem may well turn out to be an inappropriate response to it.Yet opinion polls suggest that many people nurture the belief that environmental standards are declining and some factors seem to cause this disjunction between 56 and reality.A) pose B) exaggerated C) accelerating D) extinct E) existF) perception G) wealthy H) magnified I) starving J) headK) running L) predicted M) abundant N) conception O) reducingWord Bank 3Videoconferencing is nothing more than a television set or PC monitor with a camera Through the videocenferencing, not only your voice but also your face, the surroundings and any other graphic and phisical __1__ can be captured and transmitted through the communication system with or without wires.

There are several practical reasons why bricks became important to colony. Although the forest could __1__supply sufficient timber, the process of lumbering was extremely difficult, particularly because of the lack of roads. Later when the timber on the peninsula had depleted, wood had to be brought from some __2__.Building stone was also in __3_supply. However ,as clay was plentiful, it was __4__that the colonist would turn to brick making. In addition to practical reasons for using brick as the __5__construction material, there was also an ideological reason. Brick represented __6__and permanence. The Virginia company of London instructed the colonists to build new hospitals and new _7__out of brick. In 1662,the town Act of the Virginia Assembly provided for the construction of thirty-two brick buildings and __8__the use wood as a construction material.

This strange 47 happens every five to eight years. It starts in the Pacific Ocean and is thought to be caused by a failure in the trade winds (信风), which affects the ocean currents drivenby these winds. As the trade winds lessen in 48 , the ocean temperatures rise, causing the Peru current flowing in from the east to warm up by as much as 5℃.The warming of the ocean has far-reaching effects. The hot, humid (潮湿的) air over the ocean causes severe 49 thunderstorms. The rainfall is increased across South America, 50 floods to Peru. In the West Pacific, there are droughts affecting Australia and Indonesia. So while some parts of the world prepare for heavy rains and floods, other parts face drought, poor crops and 51 .El Nino usually lasts for about 18 months. The 1982-83 El Nino brought the most 52 weather in modern history. Its effect was worldwide and it left more than 2,000 people dead and caused over eight billion pounds 53 of damage. The 1990 El Nino lasted until June 1995. Scientists 54 this to be the longest El Nino for 2,000 years.Nowadays, weather experts are able to forecast when an El Nino will 55 but they are still not 56 sure what leads to it or what affects how strong it will be.A) estimate B) strength C) deliberately D) notify E) tropicalF) phenomenon G) stable H) attraction I) completely J) destructiveK) starvation L) bringing M) exhaustion N) worth O) strike答案1.CKJCH DEOFI2.
