Nature is full of great ideas. Mary inventors watch nature for ideas to make some _______ things.

For example, a new type of cane (手杖) was invented to help blind people move around more _______. And the idea behind this invention came from the bat.

Bats make sounds when they fly at night. These sounds can't be heard by people _______ they help bats fly in the dark.

Bats send out sound waves (波) through their mouth or nose when they fly. If these sound waves _______ objects around them, they will be sent back as an echo (回声). The echo tells bats how far away things _______ trees are. It also helps them know _______ to find something to eat.

After watching how bats fly, the scientist who invented the new cane first built a lightweight cane, and then to it he _______ device (装置) that sends and receives the same sound waves as bats do while flying. Finally, he _______ the cane. It worked out!

The cane sends out sound waves. When an echo is sent back, the top of the cane vibrates(震动). This helps the person _______ the cane know how far away an object is. They will also know how big the object is.

The ________ of the cane shows that nature is really where great ideas come from.

A boy of 11 spent 93 days walking 1,700 miles from Sicily, Italy to London, the UK with his father so he could give his grandmother a special hug (拥抱). Schoolboy Romeo Cox set off from Palermo June 20 with his father Phil, 46, on a journey through Italy, Switzerland and France. The pair fought off wild dogs in Rome and even tamed (驯服) a wild donkey as they made their way back to the UK where they are now self-isolating (隔离) in Hackney.

The hard journey included boat journeys, cycling and a donkey ride but Romeo said it was easy to walk thousands of miles when heading home. The father and son’s journey involved (包含) them sleeping in churches, hostels and camping under the stars while             some people offered them their homes. Romeo finally reached Trafalgar Square on September 21, 2020, but he’ll have to wait a little longer before he can hug his beloved grandmother Rosemary, 77.

The boy, whose father is English and mother Giovanna Stopponi is Italian, is isolating before he can get together with his grandmother who lives in Witney, Oxon. Romeo said, “We got lost a few times. We slept under a wasp(黄蜂) nest, which wasn’t a good idea, got bloody feet, but we never thought about giving up.”

Romeo, who moved from Hackney, East London, to Palermo last year, has raised a great sum of money for the charity Refugee Education Across Conflicts Trust (REACT). Speaking of the journey, Romeo added, “As we got closer, I just kept thinking about seeing my Granny, and how excited I was.”

You are much older now, and hopefully wiser, although sometimes that’s not the case. You have probably forgotten about me.

I’m 12-year-old you feeling terribly nervous and stressed, hating online learning, in this horrible pandemic... I could go on and on. Does this bring any memory back to you?

Anyway, maybe there are time machines in the time where you are, but there aren’t any here, so I’m doing the next best thing: I’m writing you a letter that I hope you read every year on New Year’s Day, or New Year’s Eve.

I’ve come from 2020 to remind you not to forget. I’m sitting on my bed right now, tears still on my face from a fight with my mom ( I love her more than anything or anyone, but we’ve spent too much time together), and aware of the light blue masks hanging on the hooks next to the door in my kitchen. In a way, it still feels like March, when this whole crazy thing started. I’m sick of it.

I am begging you to remember. I didn’t get to spend Thanksgiving with my beloved grandparents, when I’d been waiting so long to act normally(正常地) with them and pod up. Now, it looks like I won’t be spending Christmas with them normally either. In America (where I live), the Coronavirus numbers are higher than they’ve ever been. I am hoping and am going to pray (祈祷) for a Christmas miracle (奇迹), but I have my doubts because I hoped for an Easter miracle and that didn’t happen.

I am having a hard time and would do anything to get out of 2020 and this pandemic, to see my friends and family normally. You are able to do that. You have what I want so badly. So please, I strongly advise you to enjoy your life, your friends, your family, your experiences.

Remember — everything is replaceable and unimportant, but people are the only true thing that matter in this modern-day world.

Love your life, and be filled with joy this year.

Sincerely,

You, age 12, Audrey in 2020, the Pandemic Year.

Jane Austen is one of Britain’s greatest female writers. She was born on 16 December 1775. She was the seventh of eight c    56    and never lived apart from her family. To entertain themselves, the children wrote and performed plays. Even as a little girl, Jane was encouraged to w    57    .

As a young woman, Jane enjoy dancing, and she went to many parties that were held in the great house of the

At the age of 14, Jane Austen wrote her first novel, Love and Friendship. In her e    60    twenties she began to write her most famous novels- Sense and Sensibility, Pride and Prejudice and Northanger Abbey. Y    61    these books were not published until many years later. Northanger Abbey was not published until 1818—a year after her death.

Japanese researchers say they are working to build the world’s first satellite (卫星) made of wood. The goal is to help fight the problem of space junk. Space junk includes things like dead satellites, lost pieces of equipment (设备) and small pieces of paint. Such objects can be dangerous to spacecraft and satellites running in space.

The project is an effort from both sides, including the company Sumitomo Forestry and Japan’s Kyoto University. The development team recently announced plans for the satellite in a news release. The researchers say the wooden satellite, which they call LignoSat, is one of several planned projects that try to explore how wood might be used in space in the future.

The design of a wooden satellite model is being developed by researchers from Sumitomo Forestry company and Japan’s Kyoto University. The developers say wood offers several advantages over other materials commonly used to build satellites, such as aluminum (铝) and other metals. For example, the researchers say wood does not stop electromagnetic waves (电磁波). For this reason, wooden structures could be used to house antenna (天线) equipment and other controlling equipment, the team said in a statement. Wooden structures would also be simpler to design and weigh less than present satellite equipment, the researchers added. Such satellites would be better for the environment because they would burn up when returning to the Earth. They would not leave very small pieces of polluting things into the air and oceans.

Space junk has already become a serious problem because it puts spacecraft and satellites running in space in       66    . To fight the problem, researchers from a Japanese company and university are working     67     to build the world’s first wooden satellite.     68     to the materials commonly used to build satellites such as aluminum and other metals, wood has at least four advantages. First of all, wood does not stop electromagnetic waves. Secondly, it is simpler to design wooden structures. Thirdly, wood is not so     69    . Lastly, wooden satellites would not cause so much     70     to the air and oceans as they would burn up and nothing of it would remain in them.

If you’re tired of common hotel rooms, maybe it’s time to climb into a tree. A new generation (一代) of tree houses are appearing across the world, and designer Rodenick Romero says he knows why and he said, “They’re magical. I’ve never seen someone climb into a treehouse and not smile.”

Before you can stay in one of the wilderness treehouses, you first have to take a boat trip down the Edisto River. And then you’ll see homes that offer a cooking gear (设备) and a comfortable sleeping bed. “It’s a really good place to get back to nature,” Romero says. The houses have gas stoves and are lit by lanterns.

Romero was greatly surprised when he first saw the buildings at this hotel 40 miles south of the Arctic Circle (北极圈) in northern Sweden. “I blew my mind. I couldn’t believe what I was seeing,” he says. The hotel rooms make good use of spare Scandinavian design. “Architecturally (建筑上) this is one of the coolest ideas for a treehouse.”

While most treehouses are found in the woods, this coffee shop and inn turns the idea on its head with a location in downtown Tokyo. The building itself stands on stilts(桩子) with a tree growing through the center of it. The cafe was the first treehouse designed by Kobayashi Takashi, who has since created more than 120 homes. “He’s one of my heroes,” Romero says. “In the treehouse community, he’s who we talk about the most.”

One of the world’s most stylish treehouses perches (栖息) in a tree alongside the Zambezi River near Victoria Falls. The large pine deck (平台) holds a bed and Turkish carpets. Guests can go on safari (陆路旅行), or simply stay in their perch and watch hippos playing in the river.
