听力原文： I am writing to thank you for the interesting reports which appeared in the July '94 edition of Saturday Evening Post. I am interested in your reports since B12 deficiency is an inherited disorder in my family. In the late 1950s and early 1960s, a research project was carried out on it by London medical school.
My grandmother was 49 when she started vitamin t312 injections in 1949, She was admitted to the hospital with a blood disease. My mother was 63 when she began vitamin B12 injections. After reading your article, I believe her treatment was started too late. At the time, she almost lost her eyesight and was told that she had another diseases.
Earlier this year, I visited my doctor and explained that 1 felt very tired and asked for a blood test to establish whether I was suffering from B12 deficiency. I was told I was much too young and that only people in their 80s suffered B12 deficiency. I told him he was wrong and that research was carried out on my family 30 years ago.
I have always believed that prevention is better than cure. I now know why I love Kellogg's Honey Nut Cornflakes. They contain vitamins, including B12! If foods contain added vitamins, as
you suggest in your article, then B12 deficiency and diseases associated with it should be left to the past.

A．It is a thank-you letter to a medical doctor.
B．It is an advertisement for vitamin B12.
C．It is a letter to the editor of a magazine.
D．It is a preface to a book on vitamins.

M: You've said a mouthful.Recently,scientists were able to help a man who lost a jawbone from cancer.They recreated bone material for his jaw from stem cells.What it means is that since the new bone was created out of the person's own cells,there was no problem with rejection because the DNA was the same.
W: I bet the person was delighted.Why would anyone oppose that sort of research？It would seem to have endless potential to benefit the human race.
M: I agree,but there are people who think we should not interfere with nature and mainipulate"what is not natural".
W: It is easier to hold such a narrow view if you're not in a position to need the benefits of the research.If you're missing a jawbone because of cancer,you probably support the research.

听力原文： As is known to all, scientists and philosophers had studied the human body and its functions from very early times. Unfortunately, many of the ideas and theories, correct and incorrect, were accepted without question for a great number of years. But by the 16th century, knowledge gained through chemical experiments was beginning to make some people think more deeply about how the human body works.
A most important medical discovery was made by William Harvey in 1628. He found out that the blood is circulated round the body in one direction only by the pumping action of the heart. It had previously been incorrectly thought that the blood moved with a backward and forward motion.
Early in the 17th century a new instrument came into use that was to open up a whole new area in the study of medical and scientific matters. This was the microscope.
The first instruments were not very efficient. They were able to magnify only a very small part of the object and this was always surrounded by rings of coloured light. Nevertheless a great step forward had been taken which was of vital importance for future research and development.
