Earthquake

1Every year earthquakes are responsible for a large number of deaths and a vast amount of destruction in various parts of the world. Most of these damaging earthquakes occur either in a narrow belt which surrounds the Pacific Ocean or in a line which extends from Burma to the Alps in Europe. Some of the destruction is directly caused by the quake itself. An example of this is the collapse of buildings as a result of the quake itself. Other damage results from landslides or major fires which are initiated by the quake.

2There are about a million quakes a year. Fortunately, however, not all of them are destructive. The intensity of an earthquake is measured on the Richter Scale, which goes from 0 upward. The highest scale recorded to date is 8.9. Major damage generally occurs from quakes ranging upwards from 6.0.

3The actual cause of the quake itself is the breaking of rocks at or below the earth's surface. This is produced by pressure which scientists believe may be due to a number of reasons, two of which are the expansion and contraction of the earth's crust and continental drift.

4In order to limit the damage and to prevent some of the suffering resulting from earthquakes, scientists are working on ways to enable accurate prediction. Special instruments are used to help people record, for example, shaking of the earth. Scientists are trying to find methods that will enable them to indicate the exact time, location and size of an earthquake.

5Certain phenomena have been observed which are believed to be the signs of imminent earthquakes. These include strange behaviors of some animals, the changes in the content of mineral water, etc. The magnetic properties of rocks may also display special pattern before major earthquakes happen.

The Weight Experiment

Nicola Waiters has been taking part in experiments in Scotland to discover why humans gain and lose weight. Being locked in a small room called a "caioriineier" (热量测试室) is one way to find out.

1. The signs above the two rooms read simply “Chamber One” and “Chamber Two”. These are the calorimeters: 4m by 2m white-walled rooms where human volunteers are locked up in the name of science. Outside these rooms another sign reads, "Please do not enter work in progress" and in front of the rooms advanced machinery registers (记录) every move the volunteers make. Each day, meals measured to the last gram axe passed through a hole in the wall of the calorimeter to the resident volunteer.

2. Nicola Walters is one of the twenty volunteers who, over the past eight months, have spent varying periods inside the calorimeter. Tall and slim, Nicola does not have a weight problem, but thought the strict diet might help with her training and fitness program.

A.self-employed community dance worker, she was able to fit the experiment in around her work. She saw an advert (广告) for volunteers at her gym and as she is interested in the whole area of diet and exercise, she thought she would help out.

3. The experiment on Nicola involved her spending one day on a fixed diet at home and the next in the room. This sequence (次序) was repeated four times over six weeks. She arrived at the calorimeter at 8:30 a.m. on each of the four mornings and from then on everything she ate or drank was carefully measured. Her every move was noted too, bet daily exercise routine timed to the last second. At regular intervals, after eating, she filled in forms about how hungry she felt and samples were taken for analysis.

4. The scientists help volunteers impose (确立) a kind of order on the long days they face in the room. “The first time, I only took one video and a book, but It was OK because I watched TV the rest of the time,” says Nicola. And twice a day she used the exercise bike. She pedaled (踩踏板) for half an hour, watched by researchers to make sure she didn't go too fast.

5. It seems that some foods encourage you to eat more, while others satisfy you quickly. Volunteers are already showing that high-fat diets are less likely to make you feel full, Believing that they may now know what encourages people to overeat, the researchers are about to start testing a high-protein weight-loss diet. Volunteers are required and Nicola has signed up for further sessions.
