　　A simple DNA test may predict whether someone is more likely to lose weight on a low fat or a low carbohydrate diet, say US researchers．The results from the small preliminary study of 101 women showed those on the best diet for their genes lost two to three times more weight than the rest．The results are being presented at an American Heart Association conference．Experts said the findings tied in with previous studies, but further work should be carried out．

　　The new field of "nutrigenomics(营养基因学)" looks at how food interacts with genes．It has long been known that people react to certain nutrients differently according to their genetic makeup．Lactose intolerance(乳糖不耐症), for example, is more common among Asians and Africans than of people of North European descent．This study looked at how well people with different genes got along with different weight-loss diets．

　　The researchers, from Stanford University, analysed data from 101 white women who provided DNA from their cheek cells．The women had different diets for a year．The diets were very low carbohydrate, low carbohydrate/high protein, and low or very low fat．The researchers divided the group into three genotypes which they described as low carbohydrate diet responsive, low fat diet responsive and a balanced diet responsive genotype．They found that those on a diet which matched their genotype lost 2-3 times more weight over 12 months compared with those on the "wrong" diet．

　　The researchers said their findings were preliminary, and need much more information before they could be used commercially．

　　British experts pointed out that the study had looked at a very small number of people and did not make clear what genes were involved．Prof．Christine Williams, from the University of Reading, said："This is a very interesting study - though very small．" She said it would be useful to get a better understanding of what genes were involved．"It fits pretty well with some of our own studies which show that certain genotypes are more responsive than others to certain types of fats, eg diets high in omega-3 fatty acids," she added．

Gaudi Nanda sees a wearable computer as a handbag --- one that's built out of four-inch squares and triangles of fiber, with tiny computer chips embedded (嵌于) in it. It looks, feels and weighs like your typical leather purse.
That's where the similarities end: this bag can wirelessly keep track of your belongings and remind you, just as you're about to leave the house, to take your wallet. It can review the weather report and suggest that you take an umbrella. This purse can even upload your favorite songs onto your scarf.
Surely, a computing purse and scarf set may seem like the stuff of science fiction. But these devices, part of next generation of wearable computers, could become commonplace within a few years. Dupont created new super strong fibers that can conduct electricity and can be woven into ordinary-looking clothes. And the chipmaker developed chip packaging allowing wearable computers to be washed, even in the heavy-duty (耐磨损的) cycle.
As a result, these new wearable devices are different from the heavy and downright silly versions of the recent past, which often required users to be wrapped in wires and type on their stomachs. Unlike their predecessors, these new wearable computers also make economic sense. When her bag becomes commercially available in two to three years, Nanda expects it will cost around $ 150, which is the price of an average leather purse.
Here's how the bag works: You place a special radio-signal-transmitting chip onto your wallet. A similar radio in your purse picks up the signal and notifies you that you've forgotten to take your wallet. In turn, sensors on your purse's handles will notify the computer that you've picked up the purse and are ready to go.
Already, these new kinds of wearable devices are being adopted for use in markets like auto repair, emergency services, medical monitoring - and even, increasingly, for consumers at large. Indeed, more people will want to cross that bridge in the coming years - making for a booming market for wearable computers that don't look like something out of science fiction.
【小题1】 According to the passage, the new wearable computers _______.

A．require users to operate on the stomach
B．pick up the signals through wires and chips
C．are being applied in some different areas now
D．are smarter but more expensive than the old ones
【小题2】What does the underlined sentence in the last paragraph mean?
A．The new wearable computers have become fashionable.
B．People would like to learn more about the new computers.
C．New wearable computers promise to sell well in the future.
D．The idea of the purse-like computers comes from science fiction.
【小题3】The purpose of the passage is to ________
A．introduce a new kind of computer
B．explain the functions of computers
C．compare different types of computers
D．show how high technology affects our life
