题目列表(包括答案和解析)
New rules will let millions of Americans know where more of their food comes from.The law is known as COOL—Country of Origin Labeling.
American Congress first passed the law in 2002.Stores have had to label seafood by country of origin since 2005.But industry pressure delayed other requirements until last week.
Products that must now be labeled include fresh fruits and vegetables, muscle meats and some kinds of nuts.But the rules are complex, and many foods are excluded.For example, organ meats are free to be labeled.So are processed foods, including cooked or smoked food.
The United States has imported more and more food in recent years to save money and expand choices.Country-of-origin labeling has become more common lately but has still been limited in many stores.
Food safety is one reason why some shoppers pay close attention to where foods came from.For example, when a large number of people recently got sick from salmonella(沙门菌病), officials blamed peppers from Mexico.Yet the last big food scare involved spinach (菠菜) grown in California.But labeling is also a way for people to know they are getting what they want.Some want to buy local foods or foods from a particular country.
The country-of-origin labeling law gives stores 30 days to correct any violations that are found.Stores and suppliers that are found to be deliberately violating the law could be fined 1000 dollars per violation.Federal inspectors are not to take action to enforce the law for six months to give time for an education campaign.
Some food safety activists say they are generally pleased with the law.They call it a good step that will give people more useful information.

How can you find out what is going on inside a person’s body without opening the patient’s body up? Regular X rays can show a lot. CAT scans can show even more. They can give a complete view of body organs.
What is a CAT scan? CAT stands for a kind of machine. It is a special X-ray machine that gets a 360-degree picture of a small area of a patient’s body.
Doctors use X rays to study and determine diseases and injuries within the body, X rays can find a foreign object inside the body or take pictures of some inside organs to be X-rayed.
A CAT scanner, however, uses a group of X rays to give a cross-sectional(横截面)view of a specific part of the body. A fine group of X rays is scanned across the body and around the patient from many different directions. A computer studies the information from each direction and produces a clear cross-sectional picture on a screen. This picture is then photographed for later use. Several cross sections, taken one after another, can give clear “photos” of the entire body or of any body organs. The latest CAT scanners can even give clear pictures of active, moving organs, just as a fast-action camera can “stop the action”, giving clear pictures of what appears unclear to the eye. And because of the 360-degree pictures, CAT scans show clear and complete views of organs in a manner that was once only shown during operation or examination of a dead patient.
Frequent appearance before X rays can cause skin burns, cancer or other damage to the body. Yet CAT scans actually don’t cause the patient to more radiation than regular X rays do. CAT scans can also be done without getting something harmful into the patient, so they are less risky than regular X rays.
CAT scans provide exact, detailed information. They can quickly find such a thing as bleeding inside the brain. They are helping to save lives.

A.It is safer than regular X rays.
B.It makes use of computer techniques.
C.It can stop the action of an organ for a short time.

C.a strange organ that has grown in the body
D.an object that gets inside the body by chance
3.What is the special use of the latest CAT scanners?
A.It provides clear photos of moving organs.
B.It can take 3-dimension(三维)pictures of inside organs.
C.It won’t cause serious skin burns, cancer or other damage to the body.
