　　The food we eat seems to have a great effect on our health. Although science has made big steps in making food more fit to eat, it has, at the same time, made many foods unfit to eat. Some research has shown that perhaps 80% human illness has something to do with food and 40% of cancer（癌症）is not a new discovery. In 1945, some researchers realized that things commonly used to keep color in meats and other food additives（添加剂）caused cancer.

　　Yet, these additives remain in our food and it is difficult to know which things on the wrappings（包装）of foods are helpful or harmful. The additives which we eat are not so direct. Farmers often give penicillin to their animals, and because of this, penicillin had been found in the milk of cows. Sometimes similar things are used to animals not for their health, but just to make more money.

　　The farmers are simply trying to fatten the animals in order to get higher price in the market. Although some countries have tried to control such things, the practice continues.

（1）According to the passage, we can know that ________.

[　　]

A. perhaps most human illness is caused by what we eat

B. perhaps most kinds of cancer have something to do with what people eat

C. cancer was discovered in 1945

D. science has made food unfit to eat

（2）Things that are used to keep colors in meat are _________.

[　　]

A. harmful

B. useless

C. helpless

D. dangerous

（3）All the additives ________.

[　　]

A. are bright and colorless

B. are not bright and colorful

C. have indirect effects on our health

D. have direct effects on our health

（4）People use additives ________.

[　　]

A. to make food more unfit to eat

B. to improve the color and taste of the food

C. to change color of the food

D. to rake off the disease of the food

（5）Which of the following is not true?

[　　]

A. Some wrappings of food are harmful

B. Farmers try to make more money on the market by fattening their animals

C. “The practice continues” means “things are still going on like that”.

　　“We cannot think of anyone who is more deserving of such an honor．He is a very special individual”, said one of his students．

　　In April 2009, Greg Perry accepted the first annual Heart of Green Local Hero Award, for his work to develop, with his high school students, the Green Dream and the Ultimated Green Classroom．At the time of the awards, he was unsteady, having just been through intense chemotherapy．His work as a teacher is an inspiration, as is his recovery, and his acceptance speech．We’re happy to say that Greg is back in the classroom－which is good th ing for him, for his students and for the wider community．Here’s his story．

　　At the age of 6 he was paralyzed from the neck down in an accident．He was told he would never walk, never play football and never feed himself．He proved the doctors wrong! He can do all these things and much more．His determination continues to thrive．

　　Perry teaches an innovative high school marketing class in Beachwood, Ohio, a city of about 12,000 in the Cleveland suburbs．Students from several area schools commute to Beachwood High School for a class unlike any other．He has led the class of 18 to create the “ULTIMATE GREEN CLASSROOM”．Under his direction the largest Eco–Friendly Showcase in Ohio was held and approximately $ 150,000 was raised in Green goods and services to build the unbelievable classroom．Elected executive officers help Perry run the class, and for much of the year, the focus is on lining of exhibitors for The Green Dream, the green business expo that is expected to draw more than 6,000 people this Spring．

　　“Sales people are making phone calls to line up exhibitors in the expo．Finance is handling the contracts and payments．Marketing and Communications and Publications and Websites are trying to promote the message．” Perry said．“it’s more like a day at work than a day at the classroom．By doing these large projects, they learn about branding, advertising, management styles and marketing techniques without every picking up the textbooks．”

阅读下列短文，从每题所给的四个选项(A、B、C和D)中，选出最佳选项。

　　The decision of the New York philharmonic to hire Alan Gilbert as its next music director has been the talk of the classical-music world ever since the sudden announcement of his appointment．For the most part, the response has been favorable, to say the least “Hooray! At last!” wrote Anthony Tommasini, a classical-music critic．

　　One of the reason why the appointment came as such a surprise, however, is that Gilbert is comparatively little known．Even Tommasini, who had advocated Gilbert's appointment in the Times, calls him “an musician with no air of the formidable(令人敬畏的)conductor about him．” As a description of the next music director of an orchestra that has so far been led by musicians like Gustav Mahler and Pierre Boulez, that seems likely to have struck at least some Times readers as faint praise．

　　For my part, I have no idea whether Gilbert is a great conductor or even a good one．To be sure, he performs an impressive variety of interesting compositions, but it is not necessary for me to visit Avery Fisher Hall, or anywhere else, to hear interesting orchestral music．All I have to do is to go to my CD shelf, or open my computer and download still more recorded music from iTunes．

　　Devoted concertgoers who reply that recording are no substitute for live performance are missing the point．For the time, attention, and money of the art-loving public, classical instrumentalists(演奏家) must compete not only with opera houses, dance groups , theater companies, and museums, but also with the recorded performances of the great classical musicians of the 20 th century．Their recordings are cheap, available everywhere, and very often much higher in artistic quality than today's choosing．The widespread availability of such recording has thus brought about a crisis in the institution of the traditional classical concert．

　　One possible response is for classical performers to program attractive new music that is not yet available on records．Gilbert's own interest in new music has been widely noted：Alex Ross , a classical-music critic, has described him as a man who is capable of turning the Philharmonic into “a markedly different, more energetic organization”．But what will be the nature of that difference? Merely, expanding the orchestra's repertoire(曲目)will not be enough．If Gilbert and the Philharmonic are to succeed, they must first change the relationship between America's oldest orchestra and the new audience it hopes to attract．

(1)

We learn from Para 1 that Gilbert's appointment has ________．
[　　]
A．	met with criticism
B．	received applause
C．	raised suspicion
D．	aroused curiosity

(2)

The author believes that the devoted concertgoers ________．
[　　]
A．	reject most kinds of recorded performance
B．	fail to recognize the variety of live performance
C．	overestimate(高估)the variety of live performance
D．	ignore the expense of live performance

(3)

According to the text, which of the following is true of recordings?
[　　]
A．	They are often inferior to live concerts in quality
B．	They are easily accessible to the general public
C．	They help improve the quality of music
D．	They have only covered masterpieces

(4)

Regarding Gilbert's role in revitalizing( 振兴) the Philharmonic, the author feels ________
[　　]
A．	enthusiastic
B．	confident
C．	puzzled
D．	doubtful
