[填空题]What Is Type 1 Diabetes
When you eat, your body takes the sugar from food and turns it into fuel. (46) . Your body uses glucose (葡萄糖) for energy, so it can do everything from breathing air to playing a video game. But glucose cannot be used by the body on its own--it needs hormone called insulin to bring is into the cells of the body.
Most people get the insulin they need from the pancreas; a large organ near the stomach. The pancreas makes insulin; insulin brings glucose into the cells; and the body gets the energy it needs. When a person has Type 1 diabetes, it is because the pancreas is not making insulin. So someone could be eating lots of food and getting all the glucose he needs, but without insulin, there is no way for the body to use the glucose for energy. (47) .
You may have heard older people talk about having diabetes, maybe people of your grandparents’ age. Usually, this is a different kind of diabetes

[单项选择]Study Helps Predict Big Mediterranean Quake
Scientists have found evidence that an overlooked fault in the eastern Mediterranean is likely to produce an earthquake and tsunami every 800 years as powerful as the one that destroyed Alexandria in AD 365.
Using radiocarbon dating techniques, simulations and computer models, the researchers recreated the ancient disaster in order to identify the responsible fault. "We are saying there is probably a repeat time of 800 years for this kind of earthquake," said Ms. Beth Shaw, an earthquake scientist at the University of Cambridge, who led the study. Scientists study past earthquakes in order to determine the future possibility of similar large shocks.
Identifying the fault for the AD 365 earthquake and tsunami is important for the tens of millions of people in the region, Ms. Shaw said. The fault close to the southwest coast of Crete last produced a big enough quake to generate a tsunami

[单项选择]World Crude Oil Production May Peak Decade Earlier Than Some Predict
In a finding that may speed efforts to conserve oil, scientists in Kuwait predict that world conventional crude oil production will peak in 2014. This prediction is almost a decade earlier than some other predictions. Their study is in ACS’ Energy & Fuels.
lbrahim Nashawi and colleagues point out that rapid growth in global oil consumption has sparked a growing interest in predicting "peak oil". "Peak oil" is the point where oil production reaches a maximum and then declines. Scientists have developed several models to forecast this point, and some put the date at 2020 or later. One of the most famous forecast models is called the Hubbert model. It assumes that global oil production will follow a bell shaped curve. A related concept is that of "Peak Oil". The term "Peak Oil" indicates the moment in which world wide production will peak, afterwards to start on irreve

[单项选择]The Best Way to Reduce Your Weight
You hear this: "No wonder you are fat. All you ever do is eating." You feel sad: "I skip my breakfast and supper. I run every morning and evening. What else can I do" Basically you can do nothing. Your genes, not your life habits, determine your weight and your body constantly tries to maintain it.
Albert Stunkard of the University of Pennsylvania found from experiments that, "80 percent of the children of two obese parents become obese, as compared with no more than 14 percent of the offspring of two parents of normal weight."
How can obese people become normal or even thin through dieting Well, dieting can be effective, but the health costs are tremendous. Jules Hirsch, a research physician at Rockefeller University, did a study of eight fat people. They were given a liquid formula providing 600 calories a day. After more than 10 weeks, the subjects lost 45kg on average. But after leaving the

[单项选择]Finding Enlightenment in Scotland

He argues that Scottish thinkers and intellectuals worked out many of the most important ideas on which modem life depend everything from the scientific method to market economics. Their ideas did not just spread amongst intellectuals, but to those people in business, government and the sciences who actually shaped the Western world.
It all started during the period that historians call the Scottish Enlightenment, which is usually seen as taking place between the years 1740 and 1800. At this time, Scotland was home to a nu
