To: Mark Hopkins＜hopkinsm@mgc.com＞ From: George Wallace＜gwallace@solarsys.com＞ Subject: March 10 Installation Date: March 1 Dear Mr. Hopkins, As we discussed earlier, I know how important it is for an assembly line to have a power source it can trust. I am sure you will find that our solar backup system is as reliable as conventional backup batteries, in addition to being more cost-effective and requiring very little maintenance. Since we will install the system outside work hours, it will not affect your schedule or cause inconvenience for your workers. If you have any questions before the installation on Saturday, do not hesitate to ask questions. Otherwise, I will see you then. Yours sincerely, George Wallace Sales Director To: George Wallace＜gwallace@solarsys.com＞ From: Mark Hopkins＜hopkinsm@mgc.com＞ Date: March 2 Dear Mr. Wallace, Thank you for your e-mail. I regret to say that we have to postpone the installation of the solar backup system. When I met you last week, I totally forgot we have an annual safety inspection by the Wellington City Fire Department on the same day we are planning to install the solar backup system. Id like to install the system on March 15 instead. I apologize for the inconvenience this may cause. Please let me know whether the date is convenient for you. Thank you. Mark Hopkins Floor Manager Micro Goods Company

听力原文：What is the color of the universe？ Two American astronomers reported their study of all the light in the universe. They said that the universe would appear to the human eye to be a light greenish color.

Karl Glazebrook and Ivan Baldry of Johns Hopkins University in Baltimore, Maryland, reported their recent finding. They presented research at a meeting of the American Astronomical Society. Their study attempted to show what people might see if they could observe the universe from far away.

The scientists gave a number value to the colors of the different star systems. Then they added the numbers together and found the average measurement. The scientists used this arrange to identify the color of the universe. They said it was a very pretty light green color. They called it "cosmic spectrum green." Many newspapers and television stations reported their finding. Other scientists and color engineers attempted to reproduce the result.

Mark Fairchild of the Rochester Institute of Technology in New York was the first person to identify a mistake. He discovered a mistake in the computer software program used by the Johns Hopkins scientists. When the mistake was corrected, the results changed. The new color of the universe is much less colorful. It is very close to white.

The scientists have apologized for the mistake. They are now working with the Rochester Institute of Technology to produce more images of the color of the universe.

What did the two astronomers from Johns Hopkins University report？

(27)

A．They reported their research on American astronomy.

B．They reported their finding on the color of the universe.

C．They reported their experiment on various star systems.

D．They reported their invention of a color identification software.

Some animals apparently can resist cancer by strengthening their immune system in preparation for winter, Johns Hopkins researchers said on Wednesday.

The scientists said their study is the first to show that the central nervous system, reacting to environmental changes, may spark changes in the body's immune system that control the growth of tumors.

They said if that is the ease, a better understanding of how the process works eventually could lead to new cancer treatments.

Dr. Randy Nelson, an associate professor of psychology at Hopkins, stressed at a meeting of the Society of Neuroscience that further study would be needed to confirm a connection between the length of the day, the animals' immune system and cancer. More work also would be needed to show that the findings could be applied to human cancer.

Dr. Faye Austin, an immunologist with the National Cancer Institute in Bethesda, said: "It's a very intriguing observation that the length of exposure to light can affect the growth of a tumour. But I think that the draws really need further work to clarify the mechanics."

But Austin said the findings were surprising and important, only because they open up a new approach for research.

Studies showed that stress weakened the immune system in animals. They figured that because winter is stressful, the season probably causes exertion (影响) on the immune system.

The researchers reasoned that animals that compensated by boosting (促进) their immune systems as winter approached would have a better chance of surviving and producing offspring.

"In the same way that animals have evolved to select the best time to breed, it struck me that animals ought to be able to predict when conditions would be challenging immunologically." Nelson said.

Dr. Nelson has drawn a conclusion that ______.

A．the findings of animals' resistance to cancer can be applied to human cancer treatments

B．the length of exposure to light can affect the growth of a tumor

C．there is a relation between the length of the day, the animals' immune system and cancer

D．there is a new approach for studying the function of central nervous system in the body's immune system

Text 1

Say the word bacteria, and most folks conjure up images of a nasty germ like staphylococcus or salmonella that can make you really sick. But most bacteria aren't bad for you. In fact, consuming extra amounts of some bacteria can actually promote good health. These beneficial bacteria are available without a prescription in drug and health-food stores and in foods like yogurt. So far, the best results have been seen in the treatment of diarrhea, particularly in children. But re searchers are also looking into the possibility that beneficial bacteria may thwart vaginal infections in women, prevent some food allergies in children and lessen symptoms of Crohn's disease, a relatively rare but painful gastrointestinal disorder.

So where have these good germs been lurking all your life？ In your intestines, especially the lower section called the colon, which harbors at least 400 species of bacteria. Which ones you have depends largely on your environment and diet. An abundance of good bacteria in the colon generally crowds out stray bad bacteria in your food. But if the bad outnumber the good—for example, after antibiotic treatment for a sinus or an ear infection, which kills normal intestinal germs as well—the result can be diarrhea.

For generations, people have restored the balance by eating yogurt, buttermilk or other products made from fermented milk. But nowadays, you can also down a few pills that contain freeze-dried germs. These preparations are called probiotics to distinguish them from antibiotics. Unfortunately, you can't always be sure that the bacteria in the products you buy are the same strains as those listed on the label or even that they're still alive. Probiotics are usually sensitive to both heat and moisture. Among the most promising and most thoroughly researched probiotics is the GG strain of Laetobacillus, discovered by Dr. Sherwood Gorbach and biochemist Barry Goldin, both at Tufts University School of Medicine. L-GG, as it's called, has been used to treat traveler's diarrhea and intestinal upsets caused by antibiotics. Even more intriguing, L- GG also seems to work against some viruses, including rotavirus, one of the most common causes of diarrhea in children in the U. S. and around the world. Here the effect is indirect. Somehow L-GG jump-starts the immune system into recognizing the threat posed by the virus.

Pediatricians at Johns Hopkins are studying a different bug, the Bb-12 strain of Bifidobacterium, which was discovered by researchers at CHR Hansen Biosystems. Like L-GG, Bb-12 stimulates the immune system. For reasons that are not dear, infants who are breast-fed have large amounts of bifidobacteria in their intestines. They also have fewer intestinal upsets. Dr. Jose Saavedra and colleagues at Hopkins have shown that Bb-12 prevents several types of diarrhea, including that caused by r0tavirus, in hospitalized infants as young as four months. It has also been used to cure diarrhea in children of all ages.

21. What the author mainly intends to say in the first paragraph is ______.

A) that nasty germs can make you really sick

B) that the word bacteria doesn't refer to the germs which make people sick

C) the beneficial effects that most bacteria may produce on human body

D) the possibility that beneficial bacteria may stop vaginal infections in women

When a 13-year-old Virginia girl started sneezing, her parents thought it was merely a cold. But when the sneezes continued for hours, they called in a doctor. Nearly two months later the girl was still sneezing, thousands of times a day, and her case had attracted worldwide attention.

Hundreds of suggestions, ranging from "put a clothes pin on her nose" to "have her stand on her head" poured in. But nothing did any good. Finally, she was taken to Johns Hopkins Hospital where Dr. Leo Kanner, one of the world's top authorities on sneezing, solved the baffling (难以理解的) problem with great speed.

He used neither drugs nor surgery, curiously enough, the clue for the treatment was found in an ancient superstition about the amazing bodily reaction we call the sneeze. It was all in her mind, he said, a view which Aristotle, some 3,000 years earlier, would have agreed with heartily.

Dr. Kanner simply gave a modem psychological interpretation to the ancient belief that too much sneezing was an indication that the spirit was troubled; and he began to treat the girl accordingly.

"Less than two days in a hospital room, a plan for better scholastic and vocational adjustment, and reassurance about her unreasonable fear of tuberculosis quickly changed her from a sneezer to an ex-sneezer," he reported.

Sneezing has always been a subject of wonder, awe and puzzlement. Dr. Kanner has collected thousands of superstitions concerning it. The most universal one is the custom of begging for the blessing of God when a person sneezes—a practice Dr. Kanner traces back to the ancient belief that a sneeze was an indication that the sneezer was possessed of an evil spirit. Strangely, people over the world still continue the custom with the traditional, "God bless you" or its equivalent.

When scientists look at the sneeze, they see a remarkable mechanism which, without any conscious help from you, takes on a job that has to be done. When you need to sneeze you sneeze, this being nature's clever way of getting rid of an annoying object from the nose. The object may be just some dust in the nose which nature is striving to remove.

The girl sneezed continuously because she______.

A．was ill

B．was mentally ill

C．had heavy mental burden

D．had attracted world-wide attention
