Apple has created a new robot named Daisy that can break a dead iPhone into pieces and find out valuable materials such as silver and tungsten (钨) in order to protect the environment.

    The robot can break up a dead phone in just 18 seconds and is a new type for Liam, another recycling robot Apple announced in 2016. Liam had 29 arms and could break iPhone into pieces within just 11 seconds.

    Daisy is able to break up 9 kinds of the iPhone, grouping them into usable parts. And it can find out valuable materials that traditional robots can't do.

    Without being stopped. Daisy is likely to do with over 1 million phones per year, a small part of the more than 2017 million phones Apple sold in 2017. The machine is programmed to carefully break up the many pieces of returned iPhones, including SIM card plates, batteries and cameras.

    It does this by taking away different parts of the iPhone bit by bit so they are all easier to recycle, separating out the valuable silver, tungsten and other parts. Computers made by other companies seem to be easier to break up. However. Apple does not make it public how many of its dead phones are recycled every year.

    Laughter is natural for people. We start to laugh at about four months of age. We start to laugh even1 we start to speak.

    Laughter connects us with others. We laugh more when we are with other people. It's difficult to pretend to laugh. Laughter is2. When people pretend to laugh, most people know it's not real.

   When do people laugh?

    Only 10 to 20 percent of laughter is about something3. Most laughter is about being friendly with other people. Most laughter says, "I don't want to4 with you. I want to be friendly with you." This kind of laughter brings people together.

    We often laugh when we feel nervous. In movies, there is often a joke at an exciting moment when everyone feels nervous. It is usually a(n)5 joke, but we laugh a lot. Our laughter helps us6.

   Why doesn't everyone laugh at the same joke?

    Not everyone has the same sense of7. Some people think a joke is funny, but other people don't think so. People have different ideas about what is funny.

    Our idea of what is funny changes with8. For young children, the world is new. They are interested in many things, so they laugh9. Teenagers often laugh to protect themselves. Adults laugh at themselves and other people with similar problems. They laugh at things that give them stress. Our10 for laughter change gradually.

More and more Americans are going to work by bike. Do you know why more people are 1 bikes to work? We can answer the question in 2 ways. First, bikes don't need gasoline(汽油), so it takes less 3 to use them. Second, a bike doesn't 4 much space(空间), so it is 5 to find a place for it. And riding a bike is good for one's 6 . People often drive their 7 to offices or to shops, but now people think riding bikes is a good way of doing sports.

Have you ever imagined Li Bai and Du Fu, two ancient Chinese poets of the Tang Dynasty, standing in front of you? At the World Robot Conference in Aug12th, the two "poets" both {#blank#}1{#/blank#}(show) up in the form of human-like robots. Dressed in {#blank#}2{#/blank#} (history) costumes. "Li Bai" was reciting his famous poem Invitation to Wine {#blank#}3{#/blank#} ‘Du Fu' was sitting beside him and listening {#blank#}4{#/blank#} (careful) with a smile on his face. 

The seven-day event took place in Beijing in August with nearly 600 kinds of robots around the world. It was {#blank#}5{#/blank#} (they) first public show for about 60 of them. 

The two "poets" developed by EXROBOTS were the most popular. They not only look like humans but also can understand human languages and follow {#blank#}6{#/blank#} (direction). They can express feelings such as joy, anger and {#blank#}7{#/blank#} (sad). Pet-shaped robots also drew a large number of visitors. The CyberDog 2, for example, do flips (空翻) and many other tricks {#blank#}8{#/blank#} a real dog. A robot cat named MetaCat with blue eyes {#blank#}9{#/blank#} soft hair will shake its head when people touch it. 

 "The robot industry will continue to make progress. "Xin Guobin, ‘vice-minister of industry and information technology, said, "And robots should play an important role in {#blank#}10{#/blank#} (deal) with common challenges in this world. They will make people live a better life in the future.
