Each one of us shares this planet with seven billion other individuals. And we all need transportation. The majority of cars, motorcycles, boats and planes cause pollution. They are also noisy. This is a serious problem in many cities. So inventors are coming up with innovative ideas to try to reduce the pollution and noise.
By Land
In many cities around the world, motorcycles are becoming increasingly popular. Currently, Vietnam has around 33 million motorcycles. China has almost 120 million. The convenience of these motorcycles comes at a cost. Air pollution is a growing problem. In large cities, people often complain it is difficult to breathe. They also complain about the noise.
To solve these problems, a U.S. company designed an environmentally friendly motorcycle. It uses electricity as fuel. You can drive it for 40 miles (64 kilometers) before recharging the battery.
It is also quiet and fast-60 miles (96 kilometers) per hour. This makes it a good choice for getting around a city.
By Water
The Italian city of Venice is a city with only a few roads. There are no cars in the city center. Instead of cars, water taxis and buses carry people along the city’s canals. The engines of these boats are simple and cheap. However, they cause pollution, particularly to the water. This causes damage to the city’s buildings.
English mechanics Dick Strawbridge and Jem Stans designed a solar-powered water taxi. The solar panels charge three electric batteries. These, in turn, provide power to the engine. The water taxi can carry six passengers. It can run for a day. In the future, solar taxis could be an alternative to Venice’s current taxis.
By Air
Designing an environmentally friendly airplane is a real challenge. Planes use an enormous amount of jet fuel. This means they cause significant air pollution, and they are very noisy. Some major airplane manufacturers have started to address the problems. They are using cleaner fuels, for example. However, Swiss engineers have gone one step further. They developed a solar airplane — the Solar Impulse. Solar panels cover its wings. These panels provide power to four electric motors and batteries. The batteries allow the plane to fly at night. This plane holds the world record for the longest solar-powered flight — 985 miles (1541 kilometers) from Arizona to Texas in the United States.

【推荐1】Three paralysed (瘫痪的) men, who were told they would spend the rest of their lives in a wheelchair, are able to walk again, thanks to an electrical device, which was placed around the men’s spines (脊柱) and boosted signals from their brains to their legs.
The first patient to be treated was 30-year-old Swiss man David M’zee, who suffered a severe spinal injury several years ago in a sporting accident. David’s doctor said he would never walk again. However, thanks to the electrical device developed by a team at a public research university in Lausanne, Switzerland, he agreed to take part in a trial led by Dr. Courtine at the university.
“I came with my daughter, Charlotte, who was one month old at the time. As we approached David, he looked her in the eye and said, ‘I will walk before you,’” Dr Courtine recalls. “When Charlotte took her first step she was 14 months old, by which time David was walking by Lake Geneva. He said to her, ‘I have beaten you.’”
David can now walk up to eight paces when the device is switched off and this is the first time that this has been recorded in a chronic (慢性的) spinal injury. However, out of the lab, in the real world, it is hard for David to walk more than a few paces. The signals from the device soon become uncomfortable and so can’t be used all the time. The system is also expensive and not reliable enough to be used out of the laboratory for day-to-day use, so it’s far from a cure.
David is the first of three patients who have benefited from the first wave of the treatment. Two other men have also managed to walk again, to various degrees.
The researchers plan to begin larger trials in Europe and the US in the next few years. If these go well, the researchers are confident the system could become more widely available.
1. How does the electrical device help the paralysed walk again?A.By straightening the spines. | B.By making the brains recover. |
C.By signaling the legs to move. | D.By making use of a wheelchair. |

【推荐2】When most people think of drones (无人机), they think of technology and fun. Safe to say, few people would think about farming. However, a group of students from York College of Pennsylvania have been building a drone that will not only help local farmers but the environment, as well.
Samantha Gotwalt and Blayde Reich, two senior Mechanical Engineering majors at York College in the group, both found the work to be quite fascinating. According to Samantha, the idea came from a York College professor, who has worked with drones, and wanted to get students involved with a project beneficial to the community. “We really want to help farming and agriculture. It’s super-important to America and our economy,” Blayde says. “We want to help the smaller farmers, and one of the perks is not having to spend their money on fertilizer and pesticides (杀虫剂).”
The idea is to design and build a drone that will take video imagery of the fields to determine what is needed to produce the best crop, while saving money and sparing the environment by reducing pollutants in the water runoff. Ideally, that data gained will help the farmers better determine what chemicals they need — and what they don’t.
However, finding the right equipment for the project was a challenge, starting with what drone the team would design for this particular usage. Samantha says she researched durability and control of drones to help make the proper determination.
“We are flying over the field and we want to have enough efficiency and go relatively slow enough that our pictures turn out well - and fly low enough that it is not using up all of its power,” she says. “The fields are a couple hundred acres(英亩), so you need your drone to be able to fly the length of that field.”
Blayde says the team continues to learn a great deal of information that will help the farmers and the environment.

【推荐3】Louis Braille was born in France in 1809. Sadly when he was a little boy, he had an accident. By the time he was four years old, he was completely blind. However, at the age of ten, Louis was lucky enough to go to one of the first schools for blind children in Paris. At this particular school they had special books. They were written in ordinary French but the letters raised up off the page, so that the students could feel the shape of the words and read them. But there were two problems with this system. First, the letters were huge and difficult to read. Second, the books were very expensive so the school library only had fourteen altogether.
In 1821, when Louis was twelve years old, a soldier came to his school. This man had invented a system for soldiers to send and receive messages in the dark. Although this idea had not worked very well, Louis became very excited and began experiments with it. By the time he was fifteen, he had invented a perfect system which used only six dots. And by 1827 the first book using his system was published.
It still took a long time before people realized what a wonderful invention Braille’s system was. In fact, Louis died in 1852 and did not live to see the success of his system, which has been adapted to almost every language in the world. Thanks to him, blind or weak-sighted people are able to read or write as well as any sighted person.

The pillage (掠夺) and destruction of ancient shipwrecks and sunken archaeological sites by treasure hunters seeking gold and other valuables may be illegal under the terms of an international treaty under discussion by UNESCO’s 188 Member States.
"Protecting our underwater heritage is extremely important and increasingly urgent as no site or shipwreck is now out of bounds for treasure hunters. New technologies have made deep-water wrecks easily accessible and these technologies are getting cheaper," warns Lyndel Prott.
According to estimates by commercial salvors (寻宝者), there are some three million undiscovered shipwrecks scattered across the world’s oceans. Even the figures for the known wrecks are impressive. The Northern Shipwrecks Database for example contains 65,000 ship loss records for North America alone from 1500 AD to the present. The Dictionary of Disasters at Sea by Charles Hocking (1969) lists 12,542 sailing ships and war vessels lost between 1824 and 1962.
Then there are sunken cities such as the trading town and pirate stronghold(海盗堡垒) of Port Royal in Jamaica, which disappeared beneath the waves after an earthquake in 1692. Or the remnants of ancient civilisations, such as the Lighthouse of Alexandria in Egypt, and the Neolithic villages being discovered under the Black Sea, which some believe could help explain Noah’s great flood.
These treasures of cultural heritage are under serious threat. Technology now allows extraordinary access to the ocean depths for determined and well-financed treasure hunters. And the potential rewards are huge. In 1985, American salvor Mel Fisher discovered the wreck of the Señora de Atocha, a Spanish ship that sank off the Florida Keys in 1622 with her cargo of gold, silver and jewellery worth an estimated US $400 million.
An archaeologist can spend ten years or more studying a ship, conserving its objects and publishing its findings. We gain an enormous amount of information and knowledge from this work. With treasure hunters, all of this is lost. This is tragic, for humanity as a whole.
1. Why is it important and urgent to protect our underwater heritage?
A.Underwater heritage is easily accessible to treasure hunters. |

【推荐2】Penguins in South Africa are being driven from their native environment because of noise from shipping activities.
The African penguins live on St. Croix island off the east coast of South Africa. The animals are already endangered. But a new study has found that African penguins are leaving their natural environment to escape noisy ship refueling operations. The island once held the world’s largest reproducing group of the animals. But the population has dropped sharply since South Africa started permitting ships in the area to refuel at sea six years ago.
Lorien Pichegru is acting director of the Coastal and Marine Research Institute at Nelson Mandela University, which led the study. She said that noise levels in the area had doubled since the refueling activities began. Scientists say high noise levels affect the ability of ocean animals to find and catch other animals for food. Noise also makes it more difficult for the animals to communicate with each other and map travel paths.
In 2016, South Africa’s Maritime Safety Authority (SAMSA) offered the country’s first offshore refueling operator’s license to Aegean Marine. Later, it gave two licenses to SA Marine Fuels and Heron Marine. An order to grant no new licenses has been in place since August 2019. It will only be lifted after an environmental study is completed by port officials. The study is expected next year. Oil-covered penguins were found in 2019 in Algoa Bay after an oil spill from ship-to-ship refueling. Environmental groups have called for the activities to be banned in the bay.
Pichegru said penguins in the area were already struggling to reproduce because of a series of issues, including industrial fishing operations. She added that the refueling activities did not kill all the penguins. “It was just the thing that made the whole ecosystem out of place and then the penguins couldn’t adapt to that,” she said.

【推荐3】From July to October every year, about a quarter of the world’s blue whales feed in the Pacific Ocean off the coast of California. But the whales currently face a major threat in their favorite feeding area. Ships carrying cargo (货物) sail in the same area at the same time. All too often, the whales’ paths and the ships’ travel lines overlap (部分重叠), and a ship will hit a whale.
According to a new study, these ship strikes have become a serious threat to the overall population of the world’s blue whales. Only about 10,000 of the creatures still exist worldwide. Blue whales are the largest known animals ever to live on Earth. Even so, if hit by a container ship, a blue whale will likely die from its injuries.
In 2007 alone, large ships killed five blue whales in the waters of San Francisco and Los Angeles, California. The National Oceanic and Atmospheric Administration (NOAA) says that because there are so few whales already, losing three to five from the California whale population every year is a significant loss. “The estimated population of blue whales in this part of the Pacific is 2,500,” says Sean Hastings, an analyst of NOAA. “So every whale counts toward this species moving off the endangered-species list.”
Now, marine scientists must figure out how to protect the whales from the giant container ships. One very simple program is already underway in the Santa Barbara Channel, a waterway that separates mainland California from the nearby Channel Islands.
The Channel Islands National Marine Sanctuary has asked large container ships passing through the area to voluntarily slow down. Sailing slower will allow the ships’ crew (船员) more time to change course before hitting a whale.
Several of the world’s largest shipping lines are set to participate in the new program. For every ship that passes through the Santa Barbara Channel at or below the reduced speed of 12 knots, the company that owns the ship will be paid $2,500.

B.Large ships often carrying goods may pollute the sea. |
C.The container ships may hit the blue whales frequently. |
D.There is fewer fish in blue whales’ favorite feeding area. |
