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 being 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 mands. 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.

(答案→)B
解析：文章介绍了一些最新的发明。
【小题1】细节题。根据第二部分第2行The Martin Jetpack allows its operator to fly 8,000 feet into the air.说明他发明的飞机飞行的高度不够。故B正确。且下一句还说明他的飞机携带的燃料太少，飞行的时间也很少。
【小题2】推理题。根据文章第三部分1,2行The EMIEW2 robot is the perfect office helper. Need a document delivered? No problem说明这种机器人是非常好的办公室帮手。故应该很受现代各个公司的欢迎。故B正确。
【小题3】细节题。根据后三部分的Green Machine中的Say goodbye to gasoline! The AirPod car runs on air power. That means this car won’t pollute the environment. 和Beef Power中的All aboard the beef train! Amtrak’s Heartland Flyer runs partly on fuel that is made from cow fat.以及最后一部分的EMILY is powered by a tiny electric pump and operated by remote control.说明这三种都是环保的，故C正确。
【小题4】细节题。根据最后一部分的Her inventor, Tony Mulligan, says that’s 15 times as fast as human lifeguards!说明这些机器人可以用作救生员。故C正确。
