Inventors are always looking for ways to make our lives easier, greener and a whole lot more fun. Take a look at the following breakthroughs in science and technology. What in the world will inventors dream up next?
Superhero Suit
Have you ever dreamed of becoming a superhero? Dream no more. There’s a real Iron Man suit, XOS 2, which instantly transforms the person wearing it. The suit provides the power to lift 200 pounds with ease and break slabs（厚片）of wood with a single karate chop. It was designed to help the military with heavy lifting. One person in the suit could do the work of three soldiers.
Up, Up and Away!
It took him 30 years to develop it, and now Glen Martin’s invention is ready to take off. The Martin Jetpack allows its operator to fly 8,000 feet into the air. Unfortunately, you can’t soar through the skies too long. The jetpack holds only 30 minutes’ worth of fuel. The aircraft will sell for $100,000.
Hardworking Robot
The EMIEW2 robot is the perfect office helper. Need a document delivered? No problem! It can also guide visitors to their destinations. The three-foot-tall robot can identify different human voices and respond to commands. One day, it may serve as a receptionist or a security guard.
Green Machine
Say goodbye to gasoline! The AirPod car runs on air power. That means this car won’t pollute the environment. A high-pressure air tank can fill the car in minutes. The three-wheeler can travel about 130 miles between fill-ups.
Beef Power
All aboard the beef train! Amtrak’s Heartland Flyer runs partly on fuel that is made from cow fat. The goal is to reduce carbon emissions by 10%. The train travels between Oklahoma City, Oklahoma, and Fort Worth, Texas.
Robo-Guard
EMILY is a robotic, four-foot-long buoy (救生圈). She can swim through riptides (激流) at up to 24 miles per hour. Her inventor, Tony Mulligan, says that’s 15 times as fast as human lifeguards! EMILY is powered by a tiny electric pump and operated by remote control.

Before astronauts can go into space, they have to have the right suit. That’s why NASA（美国国家航天和航空局）scientists are developing a new kind of space suit——lighter and more flexible than before. These new space suits will have lots of mobility(灵活性) for the astronauts, but will not need much maintenance. NASA wants the suits to include new technology that can help astronauts be safe in outer space.
Right now, the American space suit weighs about 275 pounds and is big and massive. But the suit is also easy to work in for long periods of time. The Russian space suit is less complicated, but is used only a few times and then gets thrown away.
“Finding the right balance is always going to be a challenge,” said a long-time astronaut Jeff Williams. Williams has worn both types of suits. Space suits protect astronauts from both extreme heat and freezing temperatures. They carry life-packs with oxygen for the astronauts. They also shield astronauts from radiation, or particles that send out harmful rays.
Scientists are using computers to design the new suits. This allows them to change the design again and again, and to even test the design out before actually making anything. “There’s a lot more capable tools and technology to get the job done——a lot more knowledge, as well,” said Joe Kosmo. Kosmo helped design, develop, and test suits during the Mercury, Gemini, Apollo, Skylab, and shuttle periods.
These new space suits will be much lighter and use a new kind of complex material. They also will have a smaller life support backpack, thanks to tiny electronics. NASA hopes to have the first prototypes(原型) in development by 2010 and certify(证明) the suit by 2012. This will be in time for the launch of the Orion spaceship in 2014.
【小题1】 What characteristic does the new space suit have?

Pierre is a 25-year-old penguin at the California Academy of Sciences. Due to his old age, he was going bald, which made him feel too cold to swim in the pool. Therefore, biologists at the academy had a wetsuit created for this penguin to help him get back in the swimming pool.
Unlike marine mammals, which have a layer of fat to keep them warm, penguins depend on their waterproof feathers. Without them, Pierre was unwilling to jump into the swimming pool and ended up trembling on the side of the pool while his 19 peers played in the water.
"He was cold; he would shake," said Pam Schaller, a senior biologist. Schaller first tried a heat lamp to keep Pierre warm. Then she got another idea: if wetsuits keep humans warm in the cold Pacific, why not make one for Pierre?
Schaller designed the suit, which covered Pierre’s body and had small openings for his flippers.
“I would walk behind him and look at where there were any gaps, and cut and refit and cut and refit until it looked like it was extremely suitable,” she said.
One concern was that the other penguins would reject Pierre in his new suit, but in fact, they accepted his new look. He swam freely and got along with others well, although he was the only penguin with a black stomach.
Schaller couldn’t say for sure whether the wetsuit allowed Pierre to recover his fine feathers, but “certainly we were able to keep him comfortable during a period of time that would have been very difficult for him to stay comfortable”.
Pierre will take off his suit after his new feathers grow back.

I can remember the day my father came home from the war. As he walked up the front path of our home, he saw Mum and me and he dropped the suitcase.
I was only five years old so Dad made a fuss of me, then began making an even bigger fuss of my mother. This left me free to examine all the stuff lying around the broken suitcase, and I was quick to notice a newspaper advertisement displaying a new piano. When Dad saw me holding up the newspaper cutting, he smiled.
“Yes, that’s right,” he said. “I bought your mum a piano for ten pounds down and two pounds a week.”
A few moments later, a horse pulled a cart with a piano on top. Soon we all stared at it in our small lounger room. Mum had never been close to a piano before, except at the kindergarten I attended, and she used to say how wonderful it would be if the teachers could teach her to play.
After tea that night, Mum began to teach herself to play. She plinked the keys for about two hours and drove everybody in the street mad, until Dad gently said, “Enough is enough.”
From that day on, she would plink between doing the cooking and housework. Three months went by and Mum was now a skilled pianist, holding parties with all the neighbors gathering around to sing.
Although we were poor, Mum felt like a princess and was delighted at all the attention she was receiving.
At the height of Mum’s happiness, I began to notice that Dad was looking increasingly worried. It turned out that since returning from the war, he’d been unable to find a job. Then, a few weeks later, I observed two men taking Mum’s piano away. Mum sobbed in the kitchen. Suddenly, it all became clear to me: no job, no money, no piano.
Dad finally got a job. Mum was happy again as if he’d just win the lottery(彩票). Dad had to study to qualify as an account. Every night after dinner he’d place a stack of books on the kitchen table and study late into the night. Mum didn’t say much but I could tell she was proud of Dad.
Two years later, Dad bought Mum another piano. This time he paid cash for it.
