4 . Recovering strength and movement after an injury often involves physical therapy（治疗）.Physical therapists help patients with brain or bone injuries regain control of their muscles. Exercising muscles plays an important part in the rehabilitation（康复）process. Therapists use balls and boards to improve balance, tretchy bands to increase strength and other exercise.

But a Polish technology company Egzotech has developed a robot called Luna, to make exercise interactive. Luna can help therapists choose the best exercise for their patients.The robot also provides therapists with information about their patients' progress.

Luna uses electromyography, or EMG, to identify electrical currents as patients bend their arms or legs.Michal Mikulski is the chief executive officer of Egzotech.He says detecting muscle tension not immediately visible to the human eye can help therapists design better exercise.

“We reach a certain stage of disease development when the muscle tension is not even visible. But these signals can still be seen on our machines .Luna is still able to detect them. And based on that，when the brain sends a signal to the muscle to flex, even though we don't see it, Luna is still able to detect it. It detects these signals and causes the movement of the limb（肢）,as if it were performed naturally."

Luna can also make therapy fun for children who often get bored with repeated movements. Luna permits them to play games without knowing that they are exercising their muscles.

“Sometimes it is a spacecraft, sometimes shooting balls, sometimes flying a dragon. In any case, a child wants to win a game, wants to compete, but in fact they are exercising."

Luna is just a protorype（原型）.But Egzotech expects to have other robots ready for sale later this year.

7 . Tiger research: Indonesia

While sustainable tourism helps protect many of the Indonesia’s wildlife, one of its rarest species, the Sumatran tiger, suffers as the island’s cities expand into its forest habitat. Fortunately Biosphere Expeditions have created a trip that not only benefits the seriously endangered animal, but helps protect it too. Based in a remote camp in the heart of the rainforest, volunteers will be needed to tour the landscape, documenting tracks, kills and scats (粪便) to aid important research into the lives of these big cats.

Teaching: Morocco

It’s the breathtaking beauty that draws tourists to Morocco’s High Atlas Mountains, but while the remoteness of the setting may aid its charm it also causes problems. Few inhabitants of the region’s rural villages, especially females, continue their education past primary school. Education For All (EFA) is a Moroccan NGO that builds and runs girls’ boarding houses near secondary schools in the High Atlas, making further education theoretically possible. Based in the beautiful town of Asni, the programme is looking for female volunteers with teaching experience.

Famous British physicist Stephen Hawking,     1     mental genius (智力天才) and physical disability made him a household name and inspiration across the globe, has died at age 76 on March 14^th, 2018.

Propelled (推动) to superstar by his 1988 book A Brief History of Time, which became     2    unlikely worldwide bestseller, Hawking devoted    3    (he) to unlocking the secrets of the Universe.

Hawking refused to accept the predictions that he would only live for a few years after developing a form of motor neurone disease (运动神经元病) in his early     4    (twenty). The illness gradually robbed him of mobility (移动的能力)    5    (leave) him confined to a wheelchair, almost completely paralysed and unable to speak except through his voice synthesizer (合成器). It was with these difficulties     6     he revised the draft of A Brief History of Time which was published in 1988.

    7     (translate) into thirty languages, the book has sold over ten million copies worldwide and lives on as a science book that continues to captivate (迷住) and inspire new readers each year.

When I came into contact with the book, I did not know much about the time and space. Was there a     8     (begin) of time? Could time run backwards? …These questions may be with all of us during our childhood.     9    (lucky), Stephen Hawking shows us the time and the space, the God and a mystery. The book, A Brief History of Time, is available in paperback and I     10     (strong) recommend it. For me, books like A Brief History of Time are more captivating (迷人的) than any novel.

9 . A recent event called the Human Library Project took place at the Northern Virginia, or NoVa, Community College, outside of Washington D.C. The human Library, which began 19 years ago in Denmark, grew from a youth organization called “Stop the Violence”. Today, it is a worldwide movement.

This is the third year that NoVa has held such an event. At the event, students got the chance to learn from a person — a “human book” — instead of a library book.

Najeeb Baha, a director at the college, knows about dealing with prejudice. Baha has fair skin, reddish hair and an Abraic name so people are often surprised to learn he is from Afghanistan. And even officers at airports often stop him because of that. Baha told NoVa student Angel Navia that he thought people should not focus so much on skin color, as well as people’s last name or how they speak.

Student advisor Connie Robinson was another human book. She said that college education helped her get out of a terrible situation. She was able to take control of her life. “When I talk to students, I just want them to know that whatever they are going through, you know, to continue their education is so important.”

Artist Brian Dailey was another human book. He spoke about his travels to 113 countries in seven years. Dailey said that, during his travels, he asked people he took pictures of for a one-word answer to a series of other words — such as love, freedom and war. He discovered that people in different countries often had very different answers to the same word.

Patricia Cooper, who organized the event, said that human books celebrate diversity by telling their life stories in an easy-going setting. “The goal of the human library is to talk to people in your community who you may otherwise not speak to because you have your own prejudices and hopefully to break down some of these barriers.”
