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.

years to develop a practical model that pleased people.

Humans have sewn by hand for thousands of years. It was said that the first thread was made from animal muscle and sinew (腱). And the earliest needles were made from bones. Since those early days, many people have been involved in the process of developing a machine that could do the same thing more quickly and with greater efficiency.

Charles Wiesenthal, who was born in Germany, designed and received a patent on a double-pointed needle that eliminated the need to turn the needle around with each stitch (缝合) in England in 1755. Other inventors of that time tried to develop a functional sewing machine, but each design had at least one serious imperfection. [来源:学,科Frenchman Barthelemy Thimonnier finally engineered a machine that really worked. However, he was nearly killed by a group of angry tailors when they burned down his garment factory. They feared that they would lose their jobs to the machine.

American inventor Elias Howe, born on July 9, 1819, was awarded a patent for a method of sewing that used thread from two different sources. Howe’s machine had a needle with an eye at the point, and it used the two threads to make a special stitch called a lockstitch. However, Howe faced difficulty in finding buyers for his machines in America. In frustration, he traveled to England to try to sell his invention there. When he finally returned home, he found that dozens of manufacturers were adapting his discovery for use in their own sewing machines.

Isaac Singer, another American inventor, was also a manufacturer who made improvements to the design of sewing machines. He invented an up-and-down-motion mechanism that replaced the side-to-side machines. He also developed a foot treadle(脚踏板) to power his machine. This improvement left the sewer’s hands free. Undoubtedly, it was a huge improvement of the hand-cranked machine of the past. Soon the Singer sewing machine achieved more fame than the others for it was more practical, it could be adapted to home use and it could be bought on hire-purchase. The Singer sewing machine became the first home appliance, and the Singer company became one of the first American multinationals.

However, Singer used the same method to create a lockstitch that Howe had already patented. As a result, Howe accused him of patent infringement（侵犯）. Of course, Elias Howe won the court case, and Singer was ordered to pay Howe royalties（版税）. In the end, Howe became a millionaire, not by manufacturing the sewing machine, but by receiving royalty payments for his invention.

1.Barthelemy Thimonnier’s garment factory was burned down because _____________.

A. people did not know how to put out the fire

3.Why did the court force Isaac Singer to pay Elisa Howe a lifetime of royalties?

A. Because the judge was against Singer for his surly attitude.

B. Because Howe had already patented the lockstitch used by Singer.

C. Because Singer had borrowed money from Howe and never repaid it.

D. Because Singer and Howe had both invented the same machine.

4.Which of the following would be the best title for this passage?

A. A Stitch in Time Saves Nine

The dream of flying like Buzz Lightyear never dies. For years, space-age inventors have tested one wearable jet pack after another. And time after time, the designs have been grounded by dangerous fuels, excessive weight, or very loud noise levels. Now a Canadian inventor has sidestepped those weaknesses with an aquatic jet pack. Designed for travel over lakes or oceans, it’s driven by pressurized water, not burning rocket fuel.

When Raymond Li first told the idea for the aquatic jet pack to his friends, they said he must be nuts. How could a jet pack carry that much water? Its thrust-to-weight rate would be so low and it would never become airborne. Thrust-to-weight rate is a measure of the forward force produced compared with the weight of the vehicle. A vehicle with a low thrust-to-weight rate is relatively heavy for the amount of force it generates.

Li's genius idea was to place the jet pack’s engine and its water pump in a separate boat. The pump would draw water from the lake the boat was floating on. It would then force the water under pressure through a hose connected to the jet pack. The hose would be long enough to let the pack go up as high as 8.5 meters (28 feet) in the air.

Today, Li's invention, the Jetlev-Flyer, is ready to go into production. The pack itself, complete with jet nozzles （管嘴） and handlebars, weighs just 14 kilograms. The boat is a floating pod. To take off, the operator hits a trigger on a handlebar, which starts the pump, and then turns the throttle. Two streams of high-velocity water shoot through the hose and out the nozzles, lifting the operator into the air. The operator hovers there or pushes down on the handlebars, zooming forward at speeds of up to 64 kilometers per hour, pulling the pod behind.

1.All the following factors contribute to the failure of inventing a wearable jet pack EXCEPT ______.

A. excessive water     B. unbearable noise    C. unsafe fuels   D. too much weight 

2. The underlined word “sidestepped” in Para. 1 most probably means ________.

  A. improved          B. reduced         C. avoided         D. solved

3. Raymond Li’s friends found his idea for the aquatic jet pack was ________.

  A. exciting           B. crazy          C. realistic         D. creative

4.Which of the following is TRUE according to the passage?

  A. His friends encouraged him to do the invention.

  B. He put the engine and its water pump in the same boat.

  C. The success of his invention lies in his bravery.  

  D. His invention finally succeeded and will go into production.

5.Which is the right order to make the Jetlev-Flyer take off?

  a. The throttle is turned.                  b. The operator is lifted into the air.

  c. A trigger is hit.                       d. Two streams of water shoot out.

The pump is started.

A. c, e, a, d, b          B. c, e, a, b, d            C. e, c, d, b, a          D. e, a, c, d, b

 

Intellectual property (IP) is a product of the mind that has commercial value. The concept dates back to 1623 when the first patent law to protect IP sights was passed. IP rights protect the artist from having his/her creative ideas copied by another. For example, if somebody generated an idea for a novel, that idea is protected by IP rights. If someone else wishes to represent the idea or develop it further, he/ she must consult the original artists, who will normally be rewarded financially for its use. Back in the 17th century, IP rights were primarily carried out to protect newly developed manufacturing processes against stealing. But today, intellectual property rights, are also enjoyed by those who creative music, art and literature.

In recent years, IP rights have been the focus of a great deal of discussion because of a technology which looks set to weaken them altogether; the Internet. Many years ago, if you wanted a recording of a song, you would have to purchase it from a music store; if a novel, form a book store. In those days, IP rights were easily protected since it was very difficult to obtain intellectual property without paying for it. However, a lot of IP, including songs, films, books and artwork, can be downloaded today free of charge using the Internet. This practice has now taken the world by storm, dramatically affecting the way in which we view IP rights.

1.According to the writer, in the beginning, If rights were mainly of use to ______.

A．those creating music, art and literature

B．novelists

C．engineers and inventors

D．those not receiving financial reward for their work

2.What do we know about the internet according to the passage?

A．It makes IP rights harder to protect.

B．It sells songs and films.

C．It does not affect the way we understand IP rights.

D．It prevents the production of artwork.

3.According to paragraph 2, what has “taken the world by storm”?

A．Intellectual property rights.

B．The Internet.

C．Free downloading

D．The large number of songs, films and books.

4.A possible title for this passage could be ______.

A．A History of IP Rights

B．Ways to Protect Your IP Rights.

C．The Present and the Future Of IP

D．IP Rights and Our Attitudes

 

 

Andrew Ritchie, inventor of the Brompton folding bicycle, once said that the perfect portable bike would be “like a magic carpet…You could fold it up and put it into your pocket or handbag”. Then he paused: “But you’ll always be limited by the size of the wheels. And so far no one has invented a folding wheel.”

It was a rare — indeed unique — occasion when I was able to put Ritchie right. A 19th-century inventor, William Henry James Grout, did in fact design a folding wheel. His bike, predictably named the Grout Portable, had a frame that split into two and a larger wheel that could be separated into four pieces. All the bits fitted into Grout’s Wonderful Bag, a leather case.

Grout’s aim: to solve the problems of carrying a bike on a train. Now doesn’t that sound familiar? Grout intended to find a way of making a bike small enough for train travel: his bike was a huge beast. And importantly, the design of early bicycles gave him an advantage: in Grout’s day, tyres were solid, which made the business of splitting a wheel into four separate parts relatively simple. You couldn’t do the same with a wheel fitted with a one-piece inflated （充气的） tyre.

So, in a 21st-century context, is the idea of the folding wheel dead? It is not. A British design engineer, Duncan Fitzsimons, has developed a wheel that can be squashed into something like a slender ellipse （椭圆）. Throughout, the tyre remains inflated.

Will the young Fitzsimons’s folding wheel make it into production? I haven’t the foggiest idea. But his inventiveness shows two things. First, people have been saying for more than a century that bike design has reached its limit, except for gradual advances. It’s as silly a concept now as it was 100 years ago: there’s plenty still to go for. Second, it is in the field of folding bikes that we are seeing the most interesting inventions. You can buy a folding bike for less than £1,000 that can be knocked down so small that it can be carried on a plane — minus wheels, of course — as hand baggage.

Folding wheels would make all manner of things possible. Have we yet got the magic carpet of Andrew Ritchie’s imagination? No. But it’s progress.
