share their predictions on what the world will be like in a century. If they're right, the 2114 is going to be really cool.

　　1. Robots will do your chores and more.

　　Robots will be doing most of our jobs, from building homes to teaching math. There are already robots that clean floors and pump gas. In the future they will be more complicated and useful. Unfortunately, with robots taking all the jobs, unemployment will be high.

　　2. You will read minds.

　　Speaking of being social, we will communicate in an entirely different way. Forget texts and emails. Mind­reading technology will allow us to send thoughts to each other without speaking a word. We will also be able to send thoughts to objects around us. (Instead of pressing "start" on the microwave, you could just think "start".) Meanwhile, chips implanted(植入) in our brains will improve memory and intelligence.

　　3. Your car will drive you.

　　Today, around 30,000 Americans die in car accidents each year. One hundred years from now, accidents will be a thing of the past. According to Mark Safford, consultant or the U.S. department of Transportation, future cars will drive themselves. These electric cars will communicate with other cars on the road to travel safely in close formation at high speeds.

　　4. You will eat fake meat.

　　Raising animals is not an efficient way to produce food, and it harms the environment. Cows, chickens, and pigs eat a lot, and then we have to deal with all that poop(粪便). What's more, that poop can poison lakes, rivers, and streams. Today, scientists can "grow" meat in a lab from animal cells, but it's expensive and not very delicious. In the future, they will have perfected the process. You'll order hamburgers that come from factories, not cows. Scientists may even find ways to make lab grown meat tastier and healthier than the real thing.

25. According to the passage, what is likely to happen when robots become more common in the future?

　A. People will be much lazier. B. More people will lose their jobs.

　C. People may become physically weaker. D. More people may become less intelligent.

26. Mind-reading technology will help people to ________.

　A. have a good memory B. talk to other creatures

　C. read books efficiently D. convey messages silently

27. According to the passage, in the future cars will be ________.

　A. less popular B. more expensive

　C. much easier to operate D. much smaller and lighter

28. Future meat will be ________.

　A. much more harmless B. less tasty but healthier

　C. more organic and delicious D. more environmentally friendly

C

　　The days of having to carry a phone charger everywhere could soon be over. Michigan researchers have revealed a major breakthrough in harvesting energy from human motion. They say it could lead to smart phones powered for a week by the motion of a swipe (重击).

　　Michigan State University's low-cost device, known as a nano generator, has already been tested. Scientists' success fully operated an LED touch screen, a bank of 20 LED lights and a flexible keyboard, all with a simple touching or pressing motion and without the aid of a battery. The groundbreaking findings, published in the journal Nano Energy, suggest "We're on the path toward wearable devices powered by human motion," said Nelson Sepulveda, associate professor of electrical and computer engineering and lead researcher of the project.

　　"What I foresee, relatively soon, is the capability of not having to charge your cellphone for an entire week, for example, because that energy will be produced by your movement," said Sepulveda, whose research is funded by the National Science Foundation.

　　Electrical energy is created when the device is compressed by human motion. The completed device is as thin as a sheet of paper. The device used to power the LED lights was palm-sized, while the device used to power the touch screen was as small as a finger. Advantages such as being lightweight, flexible and low -cost could make it a promising and alternative method in the field of Mechanical-energy harvesting.

　　The device also becomes more powerful when folded. Sepulveda said, "You can start with a large device, but when you fold it once again and again, it's much smaller and has more energy. Now it may be small enough to put in a specially made heel of your shoe so it creates power each time your heel strikes the ground."

　　Sepulveda and his team are also developing technology that would transmit the power generated by the heel strike to, say, a wireless headset.

29. The underlined word "device" in the second paragraph probably refers to .

　A. a piece of equipment B. a special kind of smart phone

　C. a touch screen D. a flexible keyboard

30. What can we learn about Nelson Sepulveda in the passage?

　A. He works as a journalist writing for Nano Energy.

B. He plays a major role in the project of the nano generator.
