With the development of science and technology, our life is becoming more and more convenient. It seems that 【小题1】 has been reinvented and greatly improved. But there is one thing unlike them. It’s a blind walking stick. It was invented over 100 years ago and has been used 【小题2】 many blind people for a long time. However, it had remained unchanged until an engineer named Kursat decided 【小题3】 a change. Kursat is blind. He deeply understands the difficulties and challenges that the blind face. He put some technical knowledge into his invention and invented a 【小题4】 stick. He hoped his invention would help the blind.

The smart stick uses built-in speakers and different sensors (传感器) to warn about possible dangers. It helps blind people know about the environment around 【小题5】 by using modern technology. It makes their travel much 【小题6】 than before. The stick is priced at around $500. It is less than half the price of most smart phones. Most people can 【小题7】 it.

In the future, this invention is going to make a big difference to more blind people. “It will not 【小题8】 change my life, but also the life of other people.” Kursat said, “These days, we are talking about flying cars, but the blind have been using just simple sticks. As a blind person, 【小题9】 I am at the subway station, I don’t know which is my exit. I don’t know which bus is coming or which stores are around me. But now, the smart stick can provide a lot of 【小题10】 for the blind,” he said, “I believe the life of the blind will be much more convenient and safer.”

It might be strange to wear clothes made out of plastic bottles. But 【小题1】, some clothing companies are already making such clothes.

Fashion 【小题2】 JUMA recently showed its newest collection at a workshop in Shanghai. Eighteen of them were made from recycled plastic bottles.

“We realized that people 【小题3】 billions of water bottles into landfills and oceans every year. These bottles 【小题4】 take hundreds of years to disappear. We think we should use them to 【小题5】 our clothes and help the environment,” said Alia Juma, the company’s design director.

Many other fashion companies are finding similar 【小题6】 to save our planet these days. The process is rather 【小题7】. First, the plastic bottles are washed and cut into small pieces. Then they are melted (熔化) and shaped into small balls. The balls are melted again to for thread (线). People can then use the thread to make 【小题8】 kinds of clothes.

Some people might worry about wearing something made out of plastic bottles. 【小题9】 according to Causeartist, a website that focuses on invention, clothes made from plastics could be even better than nylon (尼龙). It seems that this innovation (创新) may 【小题10】 to a greener future of fashion.

Robots seem very new to some people, 【小题1】 in fact they have a long history. The 【小题2】 robot was made by a Greek inventor (发明家). You may often see robots in lots of movies. The robots in the movies are stronger, faster and cleverer 【小题3】 people. In real life, most robots are used in 【小题4】. They are used to do many dangerous, difficult or boring jobs. Some people can’t look after 【小题5】 and robots are used to help them. For example, some people can’t see. They use dogs to help themselves move around. These dogs are 【小题6】 guide dogs. Scientists are making robots to help them. In the future, 【小题7】 dogs might take the place of these guide dogs.

Robots are also used in American hospitals. At one hospital, a robot takes meals from the kitchen to the sick people’s rooms. It never【小题8】 its way because it has a map of the hospital in its computer system (系统).

In the future, robots 【小题9】 in space. Robots will never take the place of humans, 【小题10】 they can help us in a lot of different ways.
