    All too often , a choice that seems sustainable（可持续的）turns out on closer examination to be problematic. Probably the best example is the rush to produce ethanol（乙醇）for fuel from corn . Corn is a renewable resource —you can harvest it and grow more, almost limitlessly. So replacing gas with corn ethanol seems like a great idea.
    One might get a bit more energy out of the ethanol than that used to make it, which could still make ethanol more sustainable than gas generally, but that’s not the end of the problem. Using corn to make ethanol means less corn is left to feed animals and people, which drives up the cost of food. That result leads to turning the fallow land — including, in some cases, rain forest in places such as Brazil — into farmland, which in turn gives off lots of carbon dioxide（CO2）into the air. Finally, over many years, the energy benefit from burning ethanol would make up for the forest loss. But by then, climate change would have progressed so far that it might not help.
    You cannot really declare any practice “sustainable” until you have done a complete lift-cycle analysis of its environmental（环境的）costs. Even then, technology and public policy keep developing, and that development can lead to unforeseen and undesired results. The admirable goal of living sustainable requires plenty of thought on an ongoing basis.
    小题1:What might directly cause the loss of the forest according to the text?
    A．The growing demand for energy to make ethanol.
    B．The increasing carbon dioxide in the air.
    C．The greater need for farmland.
    D．The big change in weather.
    小题2:The underline word “it” in the second paragraph refers to
    A．the energy benefitB．the forest loss
    C．climate changeD．burning ethanol
    小题3:The author thinks that replacing gas with corn ethanol is    
    A．impracticalB．acceptableC．admirableD．useless
    小题4:What does the author mainly discuss in the text?
    A．Technology.B．Sustainability.
    C．Ethanol energy.D．Environmental protection.

    小题1:C
    小题2:A
    小题3:A
    小题4:B

    小题1:推理判断题。注意问的是直接原因。That result leads to turning the fallow land — including, in some cases, rain forest in places such as Brazil — into farmland.
    小题2:根据上下文可知是指能源优势。
    小题3:作者意图判断题。根据全文可知作者认为用corn代替gas是不符合实际的，会带来很多意想不到的问题。
    小题4:主旨判断题。读完全文我们可以知道，作者主要谈论的是可持续性的判断依据以及相关一些事实。该题容易误选D。

    Eddie McKay, a once-forgotten pilot, is a subject of great interest to a group of history students in Canada.
    It all started when Graham Broad, a professor at the University of Western Ontario, found McKay’s name in a footnote in a book about university history. McKay was included in a list of university alumni （校友） who had served during the First World War, but his name was unfamiliar to Broad, a specialist in military history. Out of curiosity, Broad spent hours at the local archives （档案馆） in a fruitless search for information on McKay. Tired and discouraged, he finally gave up. On his way out, Broad’s glance happened to fall on an exhibiting case showing some old newspapers. His eye was drawn to an old picture of a young man in a rugby uniform. As he read the words beside the picture, he experienced a thrilling realization. “After looking for him all day, there he was, staring up at me out of the exhibiting case,” said Broad. Excited by the find, Broad asked his students to continue his search. They combed old newspapers and other materials for clues. Gradually, a picture came into view.
    Captain Alfred Edwin McKay joined the British Royal Flying Corps in 1916. He downed ten enemy planes, outlived his entire squadron （中队） as a WWI flyer, spent some time as a flying instructor in England, then returned to the front, where he was eventually shot down over Belgium and killed in December 1917. But there’s more to his story. “For a brief time in 1916 he was probably the most famous pilot in the world,” says Broad. “He was credited with downing Oswald Boelcke, the most famous German pilot at the time.” Yet, in a letter home, McKay refused to take credit, saying that Boelcke had actually crashed into another German plane.
    McKay’s war records were destroyed during a World War II air bombing on London — an explanation for why he was all but forgotten.
    But now, thanks to the efforts of Broad and his students, a marker in McKay’s memory was placed on the university grounds in November 2007. “I found my eyes filling with tears as I read the word ‘deceased’ （阵亡） next to his name,” said Corey Everrett, a student who found a picture of Mckay in his uniform. “This was such a simple example of the fact that he had been a student just like us, but instead of finishing his time at Western, he chose to fight and die for his country.”
    小题1:What made Professor Broad continue his search for more information on McKay?
    A．A uniform of McKay.B．A footnote about McKay.
    C．A book on McKay.D．A picture of McKay.
    小题2:What did the students find out about McKay?
    A．He trained pilots for some time.
    B．He lived longer than other pilots.
    C．He died in the Second World War.
    D．He was downed by the pilot Boelcke.
    小题3:McKay’s flying documents were destroyed in      .
    A．BelgiumB．GermanyC．CanadaD．England
    小题4:We can learn from the last paragraph that McKay     .
    A．preferred fight to his study
    B．went to war before graduation
    C．left a picture for Corey Everrett
    D．set an example for his fellow students
    小题5:What is the text mainly about?
    A．The research into war history.
    B．The finding of a forgotten hero.
    C．The pilots of the two world wars.
    D．The importance of military studies.

    Jeremy Wirick, 9, has been back in school for less than two months, but he has already had several asthma(哮喘)attacks. A recent attack happened on October 2, after he pushed himself too hard in gym class. Running, power walking, jogging and push-ups took their toll. When Jeremy got home an hour or two later, he was out of breath. He needed to use a nebulizer, a machine that helps send medicine quickly to the lungs, to get his breathing back to normal.
    Asthma attacks like Jeremy increase in September and October. More than six times as many asthma sufferers who are elementary-school age need hospital treatment in the fall as in the summer.

Alexander’s mom makes sure he has his inhaler(人工呼吸器)with him when he goes to school and that he keeps it on hand at all times. In Delaware, where Jeremy lives, kids are allowed to carry their inhalers at school.

    Michael, a typical (典型的) American, stays home on workdays. He plugs into his personal computer terminal (接线端) in order to connect with the office. After work, he puts on his headphones, watches a movie on his home video recorder, or plays baseball on the computer. On many days, Michael doesn’t talk to any other human beings, and he doesn’t see any people except the ones on television. Michael is imaginary, but his lifestyle is very possible. The inventions of modern technology seem to be cutting us off from contact with our fellow human beings.
    　　The world of business is one area in which technology is isolating (使隔离) us. Experts say, for example, that many people will soon be able to work at home. With access to a large central computer, employees such as office clerks, insurance agents, and accountants could do their jobs at display terminals in their own homes. They would never have to actually see the people they’re dealing with. In addition, the way employees are paid will change. Workers’ salaries will be automatically paid into their bank accounts(账户), making paper checks(支票)unnecessary. No workers will stand in line to receive their pay or cash their checks. Personal banking will change, too. Customers will deal with machines to put in or take out money from their accounts.
    　　Another area that technology is changing is entertainment. Music, for instance, was once a group experience. People listened to music at concert halls or in small social gatherings. For many people now, however, music is an individual experience. Walking along the street or sitting in their living rooms, they wear headphones to build a wall of music around them. Movie entertainment is changing, too. Movies used to be social events. Now, fewer people are going out to see a movie. Many more are choosing to wait for a film to appear on television or are borrowing videotapes to watch at home. Instead of laughing with others, viewers watch movies in their own living rooms.

    　　A. Games and sports.
    　　B. Personal banking.
    　　C. Music and films.
    　　D. International business.
    15. What is the main idea of the passage?
