Anyone who has had a long-term disease knows that recovering at home can be lonely. This can be{#blank#}1{#/blank#}(especial) true of children. They may feel {#blank#}2{#/blank#} (leave) out. Now, these children may have a high-tech friend to help fed less alone. A small robot may help children who are recovering from long-term illnesses. The robot like human beings takes their place at school. And their school friends must help carry the robot between classes and place the robot on their desks.

    Through the robot, a child can hear his or her teachers and friends. He or she can also attend classes from wherever they are recovering—whether at home{#blank#}3{#/blank#}from a hospital bed. Dolva, one of the scientists who {#blank#}4{#/blank#}(be) concentrating on developing the robot, explains{#blank#}5{#/blank#}the robot AVI works. She says from home, the child uses a tablet or phone to start the robot,{#blank#}6{#/blank#} (use) the same device, he or she can control the robot's movements. Inside the robots there is a small computer linked{#blank#}7{#/blank#}a 4G network. The robot is {#blank#}8{#/blank#}(equip) with speakers, microphones and cameras,{#blank#}9{#/blank#}makes communicating{#blank#}10{#/blank#}(easy). So it's the eyes and the cars and the voices at school. Hopefully AVI will help some children feel less lonely while they are absent from class.

    I was visiting Australia a few weeks ago. I knew I couldn't leave the surf capital of the world {#blank#}1{#/blank#} having a try myself. I booked a group surf lesson when I was in Byron Bay, which is a really popular place for {#blank#}2{#/blank#} (skill) surfers to go and catch some waves!

    We started off with a warm-up by doing some stretches and going for a jog along {#blank#}3{#/blank#} beach. Then we all {#blank#}4{#/blank#} (lie) down on our surfboards on the sand and practiced {#blank#}5{#/blank#} (jump) up to the standing position. After this, we were ready to go out and try it out on the water. Well, surfing is much {#blank#}6{#/blank#} (hard) than it looks—when you watch people from the beach they make {#blank#}7{#/blank#} look so easy! I had tried a couple of times but failed before one of the {#blank#}8{#/blank#} (coach) came to help me and held my board steady.

    Finally I started to get the hang of it and by the end of the lesson I managed {#blank#}9{#/blank#} (stand) up on the board by myself, {#blank#}10{#/blank#} was a pretty awesome feeling. Now I can't wait to try it again, although I'll definitely need to wear a wetsuit if I'm surfing in the UK!

    A few years ago, after a long morning of sightseeing in New York, my children and I took a rest on one of the park {#blank#}1{#/blank#} (bench) in Central Park.

    "Look!" my son said, {#blank#}2{#/blank#}(point) to a nearby rubbish bin. That's when we saw our first raccoon (浣熊). Quite at home in the big city, he paid us no attention, concentrating only on finding a {#blank#}3{#/blank#} (taste) lunch. He sorted through a few options before coming out with a wrapped sandwich {#blank#}4{#/blank#} (hold) between his paws.

    {#blank#}5{#/blank#} (surprise), rather than run away, he jumped down and walked casually to a spot on the path, not a metre from where we sat. The children were spellbound, the raccoon providing better{#blank#}6{#/blank#}(entertain) than any museum. He glanced at us, perhaps checking to see {#blank#}7{#/blank#}we were about to steal his lunch.

    {#blank#}8{#/blank#}delicate fingers, he peeled back the layers of plastic wrap until the half-eaten sandwich {#blank#}9{#/blank#} (uncover).

    Then he surprised us all. Instead of starting his food, he turned to a nearby pool of water and {#blank#}10{#/blank#} (dip) his paws in. With a casual air, he rubbed his paws together underwater for a moment, brushed his fur, then started gracefully picking at his meal.

    Scientists found that air pollution may be responsible {#blank#}1{#/blank#} a significant reduction in intelligence. The research conducted by the World Health Organization (WHO) in China {#blank#}2{#/blank#} (show) that air pollution led to big falls in test {#blank#}3{#/blank#} (score) for languages and arithmetic. The study is called "The impact of exposure to air pollution on cognitive (认知的)performance ". It was published in the Proceedings of the National Academy of Sciences journal. The study took place over four years. Researchers analyzed speaking and arithmetic tests taken by 20 000 people of all ages. They said, "Polluted air may prevent cognitive ability {#blank#}4{#/blank#} people become older.”

    The study is a warning to the rest of the world, {#blank#}5{#/blank#} (especial) to those in cities. Over 91 percent of the world population live in areas with {#blank#}6{#/blank#} (poison) air and air pollution is the {#blank#}7{#/blank#} (four) highest cause of global deaths. Researchers discovered that {#blank#}8{#/blank#} longer people were exposed to polluted air, the greater their intelligence went down. They said air pollution caused a year's worth of lost education. For those {#blank#}9{#/blank#} were over 60 years old, this could be several years. A researcher warned, "There is no shortcut {#blank#}10{#/blank#} (solve) this issue. Governments really need to take effective measures to reduce air pollution."

    Every Wednesday at 7 pm, a group of running enthusiasts from different countries gather at a bar in Shanghai before setting {#blank#}1{#/blank#} on their 5-kilometer run. But this is no ordinary run. These people {#blank#}2{#/blank#} (arm) with trash (垃圾) bags. The members of this group don't simply run for the sake of good health. They do it for the sake of the Earth {#blank#}3{#/blank#} well.

    Called "plogging", this new fitness activity originated in Sweden in 2016 and was introduced to Shanghai in 2018. The term is a combination of the words "jogging" and "plocka upp", {#blank#}4{#/blank#} means "pick up" in Swedish.

    By the summer of 2018 just a few months after Trash Running China was founded, {#blank#}5{#/blank#} (it) WeChat group had grown to include more than 400 runners. To make the activity more fun for both {#blank#}6{#/blank#} (newcomer) and regular ploggers, Trash Running China also {#blank#}7{#/blank#} (frequent) organizes longer weekend runs in the suburban areas. "We want more people to hold small 'plogging' groups and have a {#blank#}8{#/blank#} (responsible) to organize trash running activities in their own neighborhoods," says Eisenring, who founded Trash Running China." 'Plogging' is a way {#blank#}9{#/blank#} (know) the people and the city a bit more," says Robbin Trebbe, one of the {#blank#}10{#/blank#} (late) runners to join the group.

Coffee is probably world's least expensive success power tool to increase focus, drive and even the life span. {#blank#}1{#/blank#}(fortunate) we may not be enjoying its benefits or pleasure too much longer. According to ecologists，there is a good chance {#blank#}2{#/blank#} the varieties of coffee that we drink today {#blank#}3{#/blank#}(be) extinct in 20 or 30 years. The problem, of course, is the pace of climate change.

Coffee is a crop that is only grown in a thin band {#blank#}4{#/blank#}(call) the "coffee belt" close to equator(赤道), which is extremely vulnerable(易受...伤害的) to climate change. If the air is too hot {#blank#}5{#/blank#} too cold, it prevents the growth of coffee plant. Climate change also creates {#blank#}6{#/blank#}(environment) stress, which spreads pests and plant diseases. Almost all the coffee grown in the world today is one of two species, arabica or robuasta, both of {#blank#}7{#/blank#} might be wiped out in this way. There are other species existing only in Ethiopia, {#blank#}8{#/blank#}country that climate change is happening. In other words, climate change is eating away the root source that we might turn to {#blank#}9{#/blank#}replacement species.

What to do? Well, take the time {#blank#}10{#/blank#}(enjoy) each cup of coffee you drink.
