(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... It's most likely that after the iWatch comes onto the market,   _  . A) a great many tablet computers will be off the shelf B) many relevant businesses will burst on the scene C) belts with sensors will made inexpensive D) a traditional wristwatch will be unnecessary

(Question)
"Blogging is helping students to think and write more critically ,"says an Australian researcher, "and can help draw out people who would otherwise not engage in debate." These are the preliminary findings of PHD research by Anne Bartlett-Bragg, a lecturer at the University of Technology, Sydney, who has been using weblogs or blogs in her own teaching since 2001. "The students are thinking more critically." she says, "They are learning to be responsible and they're communicating outside the boundaries of the classroom and the institution, and they like that. "Bartlett-Bragg says in conventional teaching, students often rely on the lecturer as the main source of ideas and critique  for their work. "I'm a bit over listening to my students giving me back in an essay what I've told them in class." she says. "I want them to think for themselves and get different perspectives." "What makes blogs useful is their interactive nature." she says. These web-based forums for discussing ideas, experiences or opinions allow students to discuss publicly what they are studying with other students and experts outside their own university. "I really encourage them to put their personal opinion in there, provided they are informed and backed up with evidence." Bartlett-Bragg says because a lot of academics in her field of electronic or e-learning now have their own blogs, students can engage directly with them. She says one of the most powerful facilities in weblogs is pinging, which involves a person positing a comment about someone else's work on their own blog. They use the "Trackback" tool to notify the author when they have published the comment, basically inviting them to discuss it. "They get such a buzz when they make a comment on another person outside the boundaries of the institution and that person responds, or even gives them some further reading." she says. "They are getting new perspectives that I can't give them in a normal lecture." What Bartlett-Bragg likes most is that blogs can help students to   _  . A) think for themselves B) have stronger sense of responsibility C) know more about the world outside D) finish an essay assignment easily
(Answer)
A

A California family drives a car that could help protect the environment. When Jon and Sandy go to the store or to their daughters' soccer games, they drive in high-tech style. They drive a $1 million, fuel-cell-powered car. It may be the world's most expensive car and one of the most environmentally friendly cars. The FCX is the first fuel-cell-powered car to be used by a family anywhere in the world. The FCX uses hydrogen and oxygen for fuel. Car makers have been working to develop vehicles that are better for the environment. They are developing cars that use fuel other than gasoline. And then what is fuel cell technology? Fuel cell technology works by changing the chemicals hydrogen and oxygen into water. This process produces electricity, and water vapor which comes out of the exhaust pipe. Most cars release dangerous gases such as carbon monoxide and carbon dioxide. Many scientists say these gases are major contributors to global warming. "The FCX is driven just like any other vehicle on the road, but without the gases which pollute the environment," scientists say. Fuel cell technology has been around since the 1800s, but scientists have yet been to perfect it. They say it may take years before the technology is ready for widespread use. Another earth-friendly car is already on the market. Hybrid cars use both gasoline and an electric motor. They are becoming more popular with customers because they cut pollution and improve fuel efficiency. According to the passage, what is the major cause for global warming? A) Gases from FCX. B) Water vapor from cars. C) Hydrogen and oxygen. D) Gases from cars.
