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.

    Thomas is an undergraduate student at Simon Fraser University. Three years ago, he was pursuing a Science degree with the goal of {#blank#}1{#/blank#} (become) a nurse but was unsure of his next steps.

    One day {#blank#}2{#/blank#} he was attending a classroom presentation, Thomas learned about the YWCA's Boy 4 Real program. “It was {#blank#}3{#/blank#} unique experience to work with the youth, where you are giving {#blank#}4{#/blank#} (they) skills to prepare for high school.”

    Thomas has been volunteering for the program for over 3 years. His favorite parts {#blank#}5{#/blank#} (be) the community service and healthy living units, where he can share and apply what he's learning in university {#blank#}6{#/blank#} a biology student. The community service project, in which volunteers lead the youth of Grade 7 to visit a seniors home or collect cans for a food bank, is {#blank#}7{#/blank#} (especial) meaningful to Thomas.

    Volunteering with the YWCA has helped Thomas see the impact that can {#blank#}8{#/blank#} (make) by him as a mentor. Boy 4 Real gave him a {#blank#}9{#/blank#} (clear) direction of where he is headed professionally than before. Now he has made up his mind {#blank#}10{#/blank#} (continue) to stay at a school being a teacher after finishing his bachelor's degree.

    The Day After Thanksgiving (Friday) is known as Black Friday. This used to be unofficially or officially the start of holiday shopping season. Almost all stores come out with special early bird offers {#blank#}1{#/blank#} (attract) consumers to their shop. People stand in line hours before the stores are opened, to grab the bargains of the year. In the last few years, we {#blank#}2{#/blank#} (witness) a trend towards bringing those Black Friday Sales online before Friday.

    In the last few years (starting from 2013 to be precise), Black Friday Sales have started before Friday—with some stores {#blank#}3{#/blank#} (start) their Black Friday sales on Thanksgiving day or even on Wednesday and Monday. It would not be surprising to see Black Friday sale starting on Monday on the Black Friday week.

    The closest reason for {#blank#}4{#/blank#} it is known as Black Friday {#blank#}5{#/blank#} (give) in Wikipedia. Many retailers report some of {#blank#}6{#/blank#} (they) highest profits on Black Friday. The black portion of the name, “Black Friday” relates to businesses recording their {#blank#}7{#/blank#} (lose) in red ink and gains in black. This tradition lives on in modern accounting software.

    Deals websites like Dealsofamerica.com started to highlight “Black Friday sales” from 2003 {#blank#}8{#/blank#} then the retailers picked it up. {#blank#}9{#/blank#} (essential), Black Friday is an Internet term. But before it, people used to regard the sales {#blank#}10{#/blank#} “Day after Thanksgiving Sale”.

    Chinese researchers have planned to build an airport in Antarctica in November. The Chinese {#blank#}1{#/blank#} (be) not very used to flying to the southernmost continent, because the country s first polar plane, the Snow Eagle 601, {#blank#}2{#/blank#} (put) into use only three years ago.

    Before the Snow Eagle 601, Chinese researchers traveled to the ice-covered land by ship, which took significantly {#blank#}3{#/blank#} (long) than flying. There are currently more than 20 airports in Antarctica, but none of them belong to China. The Snow Eagle 601 has to rely on Russian airports {#blank#}4{#/blank#} (take) off and land. That's {#blank#}5{#/blank#} the Chinese researchers decided to build their own. Building an airport in Antarctica is very different from building one elsewhere. The continent is covered by a {#blank#}6{#/blank#} (constant) moving layer of ice, so the builders must find somewhere that moves at the slowest possible pace and in a {#blank#}7{#/blank#} (fix) direction.

    The builders managed to find a spot back in early 2017 following {#blank#}8{#/blank#} tough measuring process that took place in the storm-like polar winds. The next problem is the snow. The soft nature of snow makes {#blank#}9{#/blank#} a bad material for a runway. So the builders must use road roller-like {#blank#}10{#/blank#} (machine) to press the snow, which can be very time-consuming in extreme coldness.

Yoho National Park is a Canadian national park. {#blank#}1{#/blank#} (cover) an area of about 507 square miles, it was established in 1886. Yoho National Park {#blank#}2{#/blank#} (know) as one of the four famous national parks in the Canadian Rockies. Because of its special {#blank#}3{#/blank#} (locate), Yoho National Park has many mountains, including Mount Stephen, Mount Balfour, Mount Goodsir and so on. The {#blank#}4{#/blank#} (tall) mountain among them is Mount Stephen. There are also waterfalls in the park. Wapta Falls is the largest waterfall. And Takakkaw Falls is {#blank#}5{#/blank#} (official) known as the second highest measured waterfall.

Yoho National Park is close {#blank#}6{#/blank#} three other national parks in the Canadian Rockies. To the north is Jasper National Park, {#blank#}7{#/blank#} is the largest of the four. Banff National Park borders (接界) Yoho from the east. Kootenay National Park, {#blank#}8{#/blank#} (name) after one of the two rivers that flow into it, is located to the south.

Although most people like to visit Yoho during the summer, there are quite {#blank#}9{#/blank#} sizable number of visitors during the spring and autumn. Common summer {#blank#}10{#/blank#} (activity) include camping, climbing, hiking, fishing, and wildlife viewing.
