Nanda sees a wearable computer as a handbag, one that’s built out of four-inch squares and triangles of fabric (织物), with tiny computer chips embedded (嵌入) 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 grab an umbrella. This purse can even upload your favorite songs onto your scarf (围巾).
Sure, a computing purse and scarf set may seem like the stuff of science fiction. But these devices (装置), part of next generation of wearable computers, could become common within a few years. DuPont created new super strong fibres 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 cycle.
As a result, these new wearable devices are different from the heavy and silly types of the recent past, which often required users to be wrapped in wires and type on their stomachs. Unlike the old types, 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 inform the computer that you’ve picked up the purse and are ready to go.
Already, these new kinds of wearable devices are applied 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.

For years experts have argued that poor households are consuming less nourishing food than the rest of the population.
But a survey of some of the lowest earners in Britain shows the nutritional value of what they eat is little different to everyone else.
In fact, the same deficiencies in diet were shared by all the population and the findings suggest that poor eating choices are far more widespread than previously suspected - affecting many wealthier families.
These included low fruit and vegetable consumption, not eating enough oily fish and eating too much saturated fat and sugar.
“This is a large and significant study and it shows we are all eating just as bad a diet as each other,” said Tim Lang, professor of food policy at City University.
The poorest families were eating only slightly more sugar and slightly less fruit and vegetables, according to the study of 3,728 respondents in the bottom of the population.
Alison Tedstone, head of nutritional science at the Food Standard Agency, said: “Overall, people on low incomes have less than ideal diets, but their diets are only slightly worse than those of the rest of the population.”
The study also showed that low earners are choosing to eat unhealthily. Their food choices were not linked to their income, their access to shops or their cooking skills.
The findings appear to contradict assumptions that the poor cannot afford healthier foods or are too far away from shops that sell them.
The Low Income Nutrition and Diet Survey showed that like the rest of the population, the poor's daily fruit and vegetable intake on average is below the recommended five portions. Fewer than 10 per cent of respondents hit this target, while around 20 per cent ate less than a portion per day.
More than three quarters (76 per cent) of men and 81 per cent of women did less than one 30-minute session of moderate or vigorous exercise per week.
Some 45 per cent of men and 40 per cent of women were smokers.
This compares with 28 per cent of men and 24 per cent of women in the general population.
According to the passage, which of the following is true?
| A．Whether the poor or the rich maybe have a bad diet. |
| B．Even the poor can enjoy enough fruit and fish consumption. |
| C．Only the poor have a bad diet. |
| D．The study was conveyed in both the rich and the poor. |
What kind of persons maybe eat most sugar?
| A．The rich. | B．Men. | C．The poorest. | D．Women |
From the passage, we can learn __________.
| A．the poor choose unhealthy food because of low income |
| B．having no access to shops also leads to the poor’s bad diet |
| C．the poor’s daily fruit intake is as much as general people |
| D．the number of smokers in the poor is bigger than that in general people |
What’s the best title of the passage?
| A．The poor’s healthy problem. | B．Keep off junk food. |
| C．How to have a good diet. | D．A diet survey. |
Plastics are considered one of the most serious pollutants causing environmental problems. The garbage containing plastics end up in the waterways that eventually flow into the oceans. Accumulation (聚集)of plastic in the ocean endangers marine life and pollutes the water.
Does a plastic continent exist? Yes, a plastic continent does exist and was discovered by Captain Charles Moore a decade ago. The plastic continent is twice the size of Britain and it is the region between the Hawaii Islands and California in the central Pacific Ocean.
One of the causes of the lack of marine life in this region is due to pollution and pollutants are none other than plastics. Captain Charles Moore believes plastic waste started accumulating in the 1950s.
The plastic continent is the man-made continent of floating plastic waste. The fisher men and the sailors have avoided this region for years. The reasons are:
1. There are no fish here because of the lack of nutrients.
2. The zone also lacks the wind that is essential for sailing.
To do research on the ocean pollution, Captain Moore founded Algalita Marine Research Foundation. Other organizations such as Greenpeace supported his cause. The reports of The United Nations Environment Program show that millions of seabirds and marine animals are dying due to the invasion(入侵)of plastics. The waste plastics can be recycled, but in fact they are being thrown into the oceans. The marine animals mistake these for food and eat them. This leads to their death that affects the marine food chain.
To save the oceans from the plastic continent you need to reduce the use of plastics, reuse plastic bags and recycle plastics. What can we learn from the first paragraph?
| A．A plastic continent does exist in the Pacific Ocean |
| B．Endangered marine life is well protected. |
| C．Plastics are one of the main causes of water pollution. |
| D．Plastics should be forbidden in people’s daily life. |
What is the direct influence of the plastic continent?
| A．Local fishermen have to fish in other areas. |
| B．The water becomes shallow and fish have to move away. |
| C．The wind is too strong there and it makes sailing more difficult. |
| D．It makes people realize the importance of protecting the environment. |
It is implied that the work of plastic recycling proves to be ______.
| A．effective | B．expensive | C．a difficult task | D．not good enough |
What can we learn from the passage?
| A．Many marine animals are dying due to the broken marine food chain. |
| B．Captain Moore founded Greenpeace to do research on the ocean pollution. |
| C．The marine animals have no choice but to eat plastics for lack of food. |
| D．There are three ways to prevent the oceans from becoming a plastic continent. |
