A kitchen that gives step-by-step cooking instructions in French could inspire a revolution in language learning in the UK. By using a new technology, it speaks to you as you prepare a French dish. The kitchen breaks new ground by taking language learning out of the classroom and linking it with an enjoyable and rewarding real-life activity. The new kitchen is designed to be used in schools, universities and even people's homes. It could also be an existing kitchen. The first version of the technology was tested in the kitchens of project partner Newcastle University. The kitchen could be available for schools and universities, and for the UK market by the June of 2014. The Newcastle University team is now working on ways to put it on the market. And the European Union has given money to begin programs in six other languages, including English Italian and Spanish. Finally, versions could be developed for any language cuisine in the world. Professor Paul says, "By international standards, the UK students are now poor when it comes to learning languages--a problem that certainly has an economic influence. We believe that developing skills in a country's language and its cuisine will help change the trend." [( )] On a computer fixed into the kitchen, the user first selects the French recipe they want to follow. Digital sensors built into dishes, containers and other equipment then communicate with the computer to make sure the right instructions are given at the right time, the user can ask the computer to repeat an instruction, or translate it into English, simply by pressing the touch screen. After cooking, the user can test what they have learned by carrying out a short test on the computer. All grammar and vocabulary has been carefully selected to make sure that using the kitchen adds to basic proficiency in understanding French. Now three easy-carrying versions of the kitchen are being prepared. They're to be fixed in Newcastle University and at Institute Francais, a London-based charity devoted to... When a person is using the kitchen, _ . A) it will give him a test on his cooking skills B) it can translate French into another language C) the cooking process will stop if he goes wrong D) he must be careful so as not to make mistakes

Things are seldom what they seem.Skim milk masquerades as cream.Anil labor-saving household appliances often do not save labor.This is the surprising conclusion reached by a small army of historians, sociologists, and home economists who have undertaken, in recent years, to study the one form of work that has turned out to be most resistant to inquiry and analysis -?namely, housework. During the first half of the twentieth century, the average American household was transformed by the introduction of a group of machines that profoundly altered the daily lives of housewives.The forty years between 1920 and 1960 witnessed what might be called the "industrial revolution in the home".Where once there had been a wood or coal burning stove there now was a gas or electric range.The dryer replaced the clothes-line; the vacuum cleaner replaced the broom; the refrigerator replaced the icebox and the root cellar.No one had to chop wood any more. And yet American housewives in 1960, 1970, 1980 and even 1990 continued to log about the same number of hours at their work as their grandmothers and mothers had in 1910, 1920 and 1930.The earliest time studies of housewives date from the very same period in which time studies of other workers were becoming popular--the first three decades of the twentieth century.The sample sizes of these studies were usually quite small, and they did not always define housework in precisely the same way.but their results were more or less consistent; whether rural or urban, the average American housewife performed fifty to sixty hours of unpaid work in her home every week, and the only variable that significantly altered _ was the number of small children. A half-century later not much has changed.Survey research has become much more sophisticated, and sample sizes have grown considerably, but the results of the time remain consistent.The average American housewife, now armed with dozens of motors and thousands of electronic chips, still spends fifty to sixty hours a... What has reduced the average amount of time American housewives spend on housework? A) Dozens of motors and thousands of electronic chips. B) Sophisticated survey research. C) Larger sample sizes. D) Housewives' full-time employment in the labor force.

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 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. The best title of this passage might be_. A) the Newest Medical Invention B) New X-ray Machine to Save Lives C) How to Avoid the Damage of X Rays D) Advantages and Disadvantages of CAT Scanners
