【推荐1】Two years ago, Kursat Ceylan was in New York to give a talk about disability rights. Blind since birth, the Turkish businessman was struggling to find his hotel, holding a cane (手杖) in one hand and pulling his luggage with the other while trying to get GPS directions from his phone.

"Not surprisingly, suddenly I hit a pole," he says. "It was a bit bloody."

The problem with a cane is that, while it can tell you what's on the ground, it doesn't with objects at the body or head level. It wasn't the first time Ceylan had run into something, injuring himself.

"I have no problem with my scars, which make me more handsome, I guess," Ceylan says, laughing. "But I don't need new ones".

With WeWalk, a new smart cane he invented, Ceylan hopes to help other blind people navigate their environments more easily. The cane uses an ultrasonic(超声波) sensor to find objects at body or head level and gives a warning vibration (振动). WeWalk users pair the cane with their smartphones and then use the canes' touchpad to access features like voice assistant or navigation. Before leaving home, they can plug their destinations into Google Maps and get spoken directions as they walk. In the future, Ceylan hopes to connect WeWalk with public transportation and ridesharing services.

Ceylan sees Wewalk as part of an attempt to help blind people achieve greater freedom of movement, which he believes will give them greater access to education and jobs. The canes are already having an impact on users, Ceylan says. He recently received an email from a teacher in Ireland who had become blind as an adult. He had been depressed and housebound. But since getting a WeWalk cane, the device has kept encouraging him to go out. He has became happier and more relaxed.

【推荐3】Plastics remain one of the most-used materials for making many things. Things made of plastics can be very strong and last a long time. Plastics are also much lighter than metal and can easily be formed into different shapes. Plastics can take hundreds of years to break down on their own. And very few kinds are highly recyclable.

A team of researchers working at the US Department of Energy says it has created a kind of plastic that could lead to products that are 100 percent recyclable. It recently reported the discovery in a study in the journal Nature Chemistry.

The researchers say the new material is a plastic polymer (聚合物) called polydiketoenamine, or PDK. The team reports the material can be broken down in parts at the molecular (分子的) level. It can then be built up again to form plastics of different shapes, textures and colors.

The researchers say this process can be repeated over and over again-without the plastic material losing any performance or quality.

“Most plastics were never made to be recycled,” lead researcher Peter Christensen said in a statement. “But we have discovered a new way to assemble plastics that takes recycling into consideration from a molecular perspective.”

Many plastics have different chemicals added to them to make them more useful and powerful. The problem is that these chemicals attach to the monomers (单体), which remain in plastics even after the material gets processed at a recycling plant. The research team reported that, with the newly discovered PDK material, the monomers could be recovered and separated from any chemical additives.

Next, the researchers plan to develop PDK plastics with a wide range of thermal and mechanical properties. These plastics could be used for many kinds of cloth, as well as things such as 3D printed materials and foams. In addition, the team is trying to include plant-based matcrials in the process.

【推荐3】When it comes to saving the planet,more and more people begin to realize the importance of living green.However,more rubbish than we can imagine is being produced every day.How we deal with waste is a big environmental problem.

Waste sorting is a good way to save the planet.Waste sorting refers to the separation of waste into different kinds.Dry waste should be separated from wet waste.Dry waste is made up of anything that is naturally dry and can't be broken down,such as metal and paper while wet waste refers to organic(有机的）waste,such as trees,plant cuttings and flowers.Wet waste also refers to food that needs to be thrown away.Famous companies such as Allmetro Bins are available to offer advice about how to sort waste.

Waste sorting allows recycling factories to place all of the recyclable items together and get rid of what can't be recycled,thus doing less damage to the environment.In addition,we can reduce producing products using raw materials,which is good for the protection of natural resources(资源）。

Advanced technologies are being developed and used nowadays to help sort out waste. Even so,about another 300 factories for sorting and recycling are possible to be built by 2025 to meet the increasing need to reduce waste across Europe to the lowest possible level.

Remember:sorting at home is the first step towards recycling.By separating the glass waste from the rest,we will be doing our bit for the environment.

1. Which of the following belongs to wet waste?

A．Metal.

B．Leaves.

C．Paper.

D．Glasses.

【推荐1】A Beach in Bod-rum, Turkey, saw the horror of a human tragedy on Sept 2. A little boy, dressed in a red shirt and blue shorts, lay face down in the sand. Sadly, 3-year-old Alan Kurdi would never wake up again.

Alan drowned along with at least 12 Syrians, including his 5-year-old brother and mother. They were on a journey from Turkey to Greece. Trying to make their simple but dangerous dream of a safe home a reality, they paid with their lives. The tragic photographs of Alan’s lifeless body shocked the world. “What has drowned in the Mediterranean（地中海）is not only the refugees, but humanity,” said Turkish President.

Refugees, according to the UN, are people escaping war or persecution. Their situation is often so dangerous that they cross national borders to look for safety in nearby countries. The Kurdis wanted to head of Europe by crossing to the Greek island of Kos from Bodrum by boat.

The Kurdis’ tragedy was just one story from over 1,800 people who have died in the first six months of this year while trying to cross the Mediterranean to Europe, according to statistics released by the United Nations. Migrants, however, are not necessarily refugees. A migrant may leave his or her country for many reasons apart from war, terrorism, and persecution. They may seek employment, life with their family, or study in another country.

European countries have taken different approaches to the crisis. Germany and France are opening their doors to more asylum（避难）seekers, those who say they are refugees but the status has not been decided by the UNHCR or a government. Other countries, such as Poland, Hungary, Slovakia and the Czech Republic, have been unwilling to take a large number of refugees for various reasons including economic problems and safety concerns.

It might not seem as if the girls have much in common, but when they met at a dinner two years ago, in Kansas City, they instantly hit it off. ''We had this one little red ball to play with,'' Addyson told others. ''We didn't have any electronics or phones, no iPads or TV. It was just us playing.''

The dinner was hosted by the nonprofit group World Vision International. In some parts of the world people must walk several miles each day to collect water from a stream or another water source. Often, the water is polluted, World Vision builds wells, pipelines, and rain catchers in these communities. Addyson was at the dinner because her family supports World Vision. Maurine was there because her village been without clean water. World Vision fixed that by building a water station there. Addyson was inspired by Maurine. "People helped Maurine so she could have clean water, and kids are dying because they don't have. Races are one way World Vision raises money to pay for its water projects. Runners pledge to run a have it, "she says. ''I want to help.''

Races are one way World Vision raises money to pay for its water projects. Runners pledge to run a race, often a 26-mile marathon or 13-mile half marathon. They ask people to support them by donating to World Vision. Addyson decided to run the 2017 Kansas City Half Marathon for World Vision. At age 7, she was one of the youngest-ever runners in the race, and had to get special permission to participate.

【推荐3】History has been made at the 2015 FINA World Championships in Kazan, Russia, as men competed in synchronized swimming(花样游泳) for the first time .

There was nothing in the world that could prevent July 26, 2015 from being the best day in Bill May’s life. The 36-year-old American synchronized swimmer became the first male world champion in mixed synchronized swimming.

“It’s something that I have dreamed of my entire life,” said May. His partner Christina Jones believed “this is the future of synchronized swimming”.

Synchronized swimming has been an Olympic sport since 1984, but only as an event for women. Nevertheless, men kept training in the hope that a chance might come for them to compete at the top international level, at the Olympics or the World Championships.

“Men’s choreography(舞蹈编排) is different from women’s. It is a completely different style. In a mixed duet(混双项目) the man should personify strength and power The woman, on the contrary, beauty and grace,” Russian male synchronized swimmer Alexander Maltsev said.

However, some people still believe that synchronized swimming should be a sport purely for women. Although men are stronger, they are less flexible so it is harder to get the necessary extension in: the legs. Buoyancy(浮力) is also an issue. The sport is very difficult for men in general, because men don’t actually float like women.

As times have changed, women now can compete in every category of sport at the Olympics, but there still remain two that are closed off to men-synchronized swimming and rhythmic gymnastics(艺术体操).

Some see FINA’s change as a sign that the International Olympic Committee(IOC)may also be ready to include mixed duets soon. Nevertheless, the IOC says that it will only consider adopting male synchronized swimming after a formal request from FINA and no such request has ever been made.

It may take many years for the IOC to open the door to male synchronized swimming but if and when it does, one thing is certain. “If synchronized swimming went to the Olympics, I would definitely be there to compete,” said Bill May, “even if I am 85. ”

1. According to the passage, Bill May dreamt of _______.

A．being the first male champion swimmer at the Olympic Games
