What’s a spacewalk? Any time an astronaut gets out of a spacecraft(航天器) while in space, it is called a spacewalk. Astronauts go on spacewalks for many reasons. For example, experiments can be placed on the outside of a spacecraft. This lets scientists learn how being in space affects( 影响) different things. By going on spacewalks, astronauts can also fix things instead of bringing them back to the earth to fix.

When astronauts go on spacewalks, they wear spacesuits to keep themselves safe. Inside spacesuits, astronauts have the oxygen(氧气) they need to breathe and the water they need to drink. To keep the astronauts and the spacecraft safe, the astronauts must leave and go back to the spacecraft through a special door. When on a spacewalk, astronauts use safety tethers to stay close to their spacecraft. Tethers are like ropes, connect the spacewalkers with the spacecraft. They keep astronauts from floating( 漂 浮 ) away into space. Another way astronauts stay safe during spacewalks is by wearing a SAFER. SAFER is worn like a backpack. It helps an astronaut move around in space.

How do astronauts train for spacewalks? One way is by going for a swim.

Floating in space is a lot like floating in water. Astronauts practice spacewalks underwater in a huge special swimming pool. For every one hour they will spend on a spacewalk, astronauts need to train seven hours in the pool. Another way astronauts practice for a spacewalk is by using virtual reality(虚拟现实). It looks and feels just like a spacewalk.

Today, only three countries have finished spacewalks independently. They are Russia, the United States and China. The first person to go on a spacewalk in the world was Alexei Leonov from Russia. Zhai Zhigang is the first Chinese astronaut to go on a spacewalk. The world record of spacewalks is held by Russian astronaut Anatoly Solovyev. He has been on 16 spacewalks and spent more than 82 hours outside in space. 41. About the spacewalk, we can know

The cold wind blew strongly outside. Amaya was warm in her house, thinking about an article she’d read at school. The article was about kids who helped out their communities, and she thought it would be really cool to help her own town, Harvard.

The only problem was that she wasn’t sure how to help. In the article, the kids had grown food for people who needed food, but it was winter. She couldn’t start a garden. Amaya was deep in thought when her mom said it was time to go shopping.

As they drove along the road, Amaya saw a family walking on the sidewalk( 人 行 道 ),

wearing only light jackets. How cold they must be! That gave her an idea! She could collect winter coats, hats and gloves for people who needed them.

She shared her idea with her mom, who thought it was great. But how would they spread the idea to get plenty of winter clothing? Amaya decided to talk to her teacher, because then she could share her idea with her classmates at least.

Ms. Monroe agreed when Amaya talked about her idea. They decided to call the project Hats in Harvard. Then they wrote a letter explaining the project. Ms. Monroe even said she could help Amaya talk to the headmaster about it, so they could get the whole school to join in it. They met with the headmaster during lunch time. He was excited about the idea, and said he would make sure copies(复印件) of the letter went home with all the students.

They collected enough winter clothing in only one week. Then they left the clothes around two parks, so families who needed clothes could get them there. Three days later, Amaya and her mom went shopping again. She saw the same family that had given her the idea for Hats in Harvard. This time, though, the family looked nice and warm in some new coats, hats and gloves. Amaya felt warm in her heart, and was very glad she could help others. 46.

How did they know Scrub belonged to Jennifer? How did they know Jennifer’s phone number? All the information was available because of the microchip, a very small computer chip(薄片). It was placed under Scrub’s skin many years earlier.

The microchip is usually placed under the skin of an animal’s shoulder to keep its ID number. Once the chip is in place, the pet does not feel it anymore. When lost pets are brought to animal shelters, people there use a special tool to look for the microchip and read the ID number on it, then they’ll call the microchip company to match the number to the information of the pet’s owner. This is how the shelter was able to tell Jennifer that they had found Scrub.

Microchips have helped thousands of owners get their lost pets back. In New York, a dog named Roxy was missing for months. Then a woman found her on a busy street in New Jersey. No one knows how the dog got to a different state. However, thanks to her microchip, Roxy was soon returned to her grateful owner.

In 2008, a couple got their cat George back after he had disappeared 13 years earlier! When

George got lost, the couple tried everything to find him. They visited animal shelters every day for six months, made posters and even offered a $500 reward(酬金). As years went by, they thought George would never be back till they got the call from an animal shelter. Without the microchip, the cat would never be able to come home again.

Microchips can not only work for a pet’s whole life but help lost pets no matter how far they’ve been away from home. This is why microchips may be just the thing to help bring missing pets back home. 51. How did Jennifer find her pet cat?

A. By visiting animal shelters. B. By offering a $500 reward.
