D) It may trigger a new wave of fake food production.
Imagine eating everything delicious you want - with none of the fat. That would be great, wouldnt it?
New fake fat products appeared on store shelves in the United States recently, but not everyone is happy about it. Makers of the products, which contain a compound called olestra, say food manufacturers can now eliminate fat from certain foods. Critics, however, say the new compound can rob the body of essential vitamins and nutrients and can also cause unpleasant side effects in some people. So its up to decide whether the new fat-free products taste good enough to keep eating.
注：eliminate消除
Chemists discovered olestra in the late 1960s, when they were searching for a fat that could be digested by infants more easily. Instead of finding the desired fat, the researchers created a fat that cant be digested at all.
Normally, special chemicals in the intestines grab molecules of regular fat and break them down so they can be used by the body. A molecule of regular fat is made up of three molecule of substances called fatty acids.
The fatty acids are absorbed by the intestines and bring with them the essential vitamins A, D, E, and K. When fat molecules are present in the intestines with any of those vitamins, the vitamins attach to the molecules and are carried into the bloodstream.
Olestra, which is made from six to eight molecules of fatty acids, is too large for the intestines to absorb. It just slides through the intestines without being broken down. Manufacturers say its that ability to slide unchanged through the intestines that makes olestra so valuable as a fat substitute. It provides consumers with the taste of regular fat without any bad effects on the body. But critics say olestra can prevent vitamins A, D, E, and K from being absorbed. It can also prevent the absorption of carotenoids , compounds that may reduce the risk of cancer, heart disease, etc.
Manufacturers are adding vitamins A, D, E, and K as well as carotenoids to their products now. Even so, some nutritionists are still concerned that people might eat unlimited amounts of food made with the fat substitute without worrying about how many calories they are consuming.

Part IV Short Answer Questions
Joe Templer should have known better: after all, he works for a large auto-insurance company. It wont hurt to leave the key in the truck this once, he thought, as he filled his gas tank at a self-service gas station. But moments latter as he was paying the money he saw the truck being driven away.
In 1987, 1.6 million motor vehicles were stolen in the United States-one every 20 seconds. If current trends continue, experts predict annual vehicle thefts could exceed two million by the end of the decade.
Vehicle theft is a common phenomenon, which has a direct impact on over four million victims a year. The cost is astonishing.
Many police officials blame professional thieves for the high volume of thefts. It is a major money-maker for organized crime. Typically, stolen cars are taken to pieces and the parts sold to individuals. But as many as 200.000 cars are smuggled out of the country every year. Most go to Latin America, the Middle East and Europe.
Only about 15 percent car thefts result in an arrest, because few police departments routinely conduct in-depth auto-investigations. When thieves are arrested, judges will often sentence them to probation , not immediately put them in prison because the prisons are overcrowded with violent criminals.
One exception is a Michigan program that assigns 92 police officers to work full-time on the states 65,000 car theft cases a year. Since 1986, when the effort began, the states auto-theft rate has fallen from second in the nation to ninth.
How can you protect your car? If you live in a high-theft area or drive an expensive model, consider a security system. It may cost anywhere from $25 to $1,000. Some systems engage automatically - simply removing the key disables the fuel pump the fuel pump and the starter. When cars are equipped with such systems, thefts may drop by one-third. In some states, you may be able to sue a device that transmits radio signals, allowing stolen cars to be tracked by police.
