One of the strangest and most fascinating things about Scotland is the Loch Ness Monster.

Some people believe in the monsters【B1】______Many do not! However, very important【B2】______people do believe there is some truth in the famous monster story: experts from Britains Royal Air Force, scientists from the Boston Academy of Applied Science and specialists from NASA, to【B3】______but a few! Loch Ness is an【B4】______lake in Northern Scotland. It is about twenty-four miles long and one mile wide, and【B5】______1,000 feet, which makes it very difficult for anybody to find and examine the monster. In fact the first【B6】______reports of people seeing the monster date from only about six years before the beginning of the Second World War. Since then there have been other【B7】______and photographs of the monster. Many of these photographs【B8】______silly jokes played on an unsuspecting public later. However, other photographs have amazed the most searching scientific minds. In fact, it seems certain that something does exist in the deep waters of the【B9】______lake. The most amazing photographs show a flipper — the flipper perhaps of a very large animal. From these photos British expert in animal life, Sir Peter Scott, who is also an artist, has【B10】______the picture of what he believes the monster might look like.

第三篇

Many science reports discuss medical studies that test the effect of a new drug. Usually, a large number of people is divided into two groups. Each group takes a different substance. But no one knows which group is getting which substance. One group takes the medicine being tested. Another group takes what we call an inactive substance. Medical researchers call this substance a "placebo." The word "placebo" is Latin for "I shall please." Placebo pills(宽心丸)usually are made of sugar.

Using placebos to test drugs sometimes has a surprising result. Researchers say people taking the placebo often report improvements in their health. This is known as "the placebo effect"--pain that is eased or stopped by an inactive substance. In such testing, the drug must perform. better than the placebo to prove that it is effective.

Doctors have reported that the placebo effect can be used in treatment. For example, a doctor tells a patient that a new drug will stop the pain in his leg. The pill is only sugar. But the patient does not know that. He takes the pill and says his pain is gone.

Scientists are beginning to discover some physical reasons for this reaction in some people. They are learning that much of what people believe to be true comes from what the brain expects is going to happen. If the brain believes a drug will ease pain, the brain may begin physical changes in the body that can cause the expected effect. A recent examination of studies on drugs for depression found that placebos eased the depression about as well as the active drugs.

Other studies have explored the power of placebos. A study in Japan involved thirteen

people who reacted to the poison ivy (常青藤)plant. Poison-ivy causes red itchy sores(伤痕)on some people who touch it. Each person was rubbed on one arm with a harmless leaf, but was told it was poison ivy. Each person was then touched on the other arm with poison ivy, but was told it was a harmless leaf. All thirteen people developed a reaction on the arm where the harmless leaf touched their skin. Only two reacted to the poison ivy leaves.

Doctors and scientists worry that the use of placebos may not always be harmless. They say people can become victims of false doctors and others who use placebos to claim they can cure disease.

What do medical researchers usually use to make placebo pills？

A. Ivy leaves.

B. Harmless leaves.

C. Medicine being tested.

D. sugar.

听力原文：Today, we discuss one way foreign students earn money while attending graduate sc

听力原文： Today, we discuss one way foreign students earn money while attending graduate school. They can work as teaching assistants. Teaching assistants are known as TA for short. They usually work about twenty hours each week. They are paid to help college professors teach large numbers of students in lower level classes. Generally, the professor gives a talk or lecture to all the students in a large class one or two times a week. The teaching assistant leads another smaller class each week. The teaching assistant gives tests and reads any homework or reports the students may be required to write. TAs also meet with individual students seeking help. They attend teaching meetings. And they help organize laboratory equipments if they are helping to teach a science class.

Most American colleges and universities must honour legal requirements when employing international students as teaching assistants. One of these is that the TA must speak good English. Many university departments require all TAs from non-English-speaking countries to take one of two English speaking tests.

One of these is the Test of Spoken English, or TSE. It is offered by the Educational Testing Service. Foreign students can take the test before they arrive in the United States. The other test is the Speaking Proficiency English Assessment Kit, known as the SPEAK test. The college or university usually gives this test to make sure that students will be able to understand the foreign teaching assistant.

For example, the University of West Virginia in Morgantown uses foreign teaching assistants. The university requires a good score on either test before an international student is permitted to teach. The university also suggests that foreign graduate students give a short talk to a group of people to make sure they will be understood.

听力原文：A new book by two professors at Pennsylvania State University compares public edu

听力原文： A new book by two professors at Pennsylvania State University compares public education systems around the world. The book is called National Differences, Global Similarities: World Culture and the Future of Schooling.

David Baker and Gerald LeTendre led a group of researchers who gathered information on about 50 countries. Some findings came from the Third International Mathematics and Science Study. That study took place in 1994 and again five years later.

The professors say education is increasingly shaped by what they call “transnational forces”. Officials in many counties are concerned about how their students compare with students in other countries.

Each part of the book develops a different subject researched in schools around the world. One of the subjects is violence among students. The professors say countries with the most school violence include Hungary, Romania and the Philippines.

They say the United States is somewhere in the middle, above nations like New Zealand, Canada, South Korea, Spain and Australia. The findings are based on reports from students.

Professor Baker says inequalities in educational systems act as an influence. He says schools that are sharply divided between “winners and losers” in math have higher levels of violence. “This does not mean that nations should stop trying to raise scores,” he says. “But they should be careful to raise the performance among all students.”
