(CNN) -- In the last week, the Apple iWatch has made the jump from unlikely rumor to a real product that's probably in development, thanks to reports showing up in various publications. The clues are planting the seeds of an Apple watch in consumers' minds. The general public has not been crying out for a better watch. And Apple prides itself on knowing what the people want before they do, and an Apple watch would be much more than just a fancy timepiece. It's not about the watch form factor, but creating a wearable mobile device that takes advantage of advances in mobile computing technology such as cheap sensors, better battery life and improved voice recognition. If executed correctly, an Apple watch could bring about a profitable industry of products to go with it, like it did with the iOS App Store and mobile applications. "It's unlimited, the number of wearable things you can put into," said Gene Munster, an analyst with Piper Jaffray, who imagines small companies making inexpensive products like belts with sensors that send warnings to the watch when you've eaten too much. Apple is not entering virgin territory. There are already a handful of fancy smart watches available, but most act as accessories , connecting to the more powerful Android and iOS smartphones and tablets over Bluetooth. For example, the new Pebble smart watch passes on alerts from a smartphone, so when you receive a text, e-mail, or Facebook notification it is pushed to the watch, which vibrates . Wearable technology is also booming, thanks to cheap sensors that can be used to track things like movement and heart rates. The number of wearable fitness products has been growing at a fast pace, but an Apple offering would shake up the industry completely. "We're finally getting some players involved, and Apple is the real one that can add some value to some of this wearable technology," said Munster. Apple isn't alone in seeing the potential for this type of technology. Google is working on its own wearable platform, Google Glasses. The... This passage should be put under the category of _ .

Q: The message what the "Eat up All on Your Plate" campaign tries to convey is not new. Our ancestorshad poems about the importance of frugality in the consumption of food. But it makes a lot of sensewhen many are yet to have the awareness that food waste borders on a crime. The campaign has been started online and thousands of people have answered the call. Manyrestaurants have joined the program by announcing that customers are encouraged to order half a dish andtake home what they can't finish. However, it is estimated that 50 million tons of grain are wasted every year in China, enough tofeed 200 million people for a year. True, official banquets paid with public money contribute much to such waste. But it isimportant that everyone thinks about how they can do their bit to reduce food waste. We need to developthe habit of never ordering or cooking more than we can eat and feeling guilty when we dump ourleftovers. Many people have a bad habit of entertaining guests with more than enough food, believing that theyhave not satisfied their guests' appetites if there is no food left on the table. In fact, to be a good host theyorder more than their guests can possibly eat and their guests eat more than they want out of politeness. Such a mentality needs to change. People need to be made aware that it is impolite to force guests toeat more than they are comfortable with and it is insensible and uncivilized to waste food. Even if one iswealthy, ordering more than one can eat is a bad way to show off one's wealth. The writer thinks the campaign "Eat up All on Your Plate" makes sense because _ . A) some people have some bad eating habits B) some officials are wasting a lot of food C) wasting food is still rather common in China D) saving food is a traditional virtue of China

Q: As I was thinking about language learning the other day, the image of baking bread came into my mind. I compared some of the exercises and drills that we put ourselves through in order to learn a language to the various ingredients that go into baking a loaf of fresh bread. Real language learning takes place in human relationships. No one sits down and eats a cup of flour, even if he is hungry and in a hurry. You don't become bilingual by learning lists of vocabulary. You don't become a speaker of a language by memorizing verb conjugations and agreement rules. You become bilingual by entering a community that uses that other language as its primary means of communication. I am not suggesting that we can make bread without ingredients. Flour is necessary, as are yeast , salt, water and other ingredients. Vocabulary is part of any language and will have to be learned. Grammatical rules exist in every language and cannot be ignored. But merely combining the appropriate ingredients in the recommended proportions does not result in bread. At best, you only end up with a ball of dough . In order to get bread, you have to apply heat to the dough. And in language learning, that heat comes from the community. Anyone who has learned a second language has experienced that heat. It creeps up your neck when you ask the babysitter, "Have you already been eaten?" when you meant to say, "Have you already eaten?" When you try to say something quite innocent and the whole room bursts into laughter, you are experiencing the heat that turns raw dough into good bread. Remember the old saying, "If you can't stand the heat, get out of the kitchen"? This is where language learning often breaks down because we find the heat uncomfortable and we stop the baking process. In order words, we can't stand the heat, so we get out of the kitchen. However, the language learner who stays in the kitchen--in the heat--until the combined ingredients are thoroughly transformed will enjoy the richness of a quality loaf of bread. He is lad that... You can become a speaker of a language by _ . A) bearing millions of words and expressions in your mind B) using the language to communicate with those around you C) knowing verb conjugations and grammatical rules D) saying something innocent to be laughed at by others
