1 . Shenyang—The remains of 117 Chinese People’s Volunteers soldiers killed in the 1950-53 Korean War returned to China on Sunday before the Commemorative Day of Martyrs.

This is the seventh annual repatriation (遣送), following a handover agreement signed between China and the Republic of Korea. and also the largest since the initial (最初的) return of 437 soldiers in 2014. Between 2014 and 2019, the remains of 599 soldiers were returned.

Earlier on Sunday, the ROK handed over the remains at a ceremony at Incheon airport outside Seoul. A Chinese military transport plane, escorted (护卫) by two Chinese fighter jets, carried the remains and belongings of the fallen soldiers back and landed at Taoxian International Airport at 11:18 am in the northeastern Chinese city of Shenyang near the border of the Democratic People’s Republic of Korea. Y-20 aircraft. the largest and most advanced domestically developed transport aircraft. carried out the task for the first time. It was labeled (贴标签于……) with the serial number 01. as a mark of high respect for the martyrs.

Vice Premier Sun Chunlan attended the ceremony along with CPV soldiers and citizens. China has never forgotten its fallen heroes and the contribution they made, Sun said in a speech.

Chinese people always remember the fighting spirit of defending the motherland, and China will remember the past and cherish peaceful international environment, Sun said.

Wang Guobin, a 92 year old CPV veteran, said. “I’m both happy and sad. I’m glad that after 70 years, they finally come home. And I am sad that they died in the 1950-53 Korean war and couldn’t come back until 70 years later.”

Many local residents lined the roads to welcome the martyrs home and show their respect.

The remains will be buried in a martyrs’ park in Shenyang on Monday. It is the resting place of all soldiers’ remains returned by the ROK since 2014.

This year marks the 70th anniversary of the CPV’S participation in the 1950-53 Korean War. A total of 2.9 million CPV soldiers entered the battlefield, and 197,653 of them were killed in the war.

2 . It might seem like something from a science fiction movie, but scientists today are working on ways to combine certain kinds of bacteria with tiny robots. Scientists want to use these creations to improve the way we give medical treatment. They claim that drug therapy (疗法), disease diagnosis, and even surgery could be greatly aided by the use of nanobiotechnology. Nano-means “tiny”, and bio-means “life”. This tiny technology will use living organisms in combination with electronics.

Electronics makers already use tiny robots to build complex but very tiny circuits. Medical scientists want to use these robots to repair patients’ damaged organs or to direct medicines to affect specific cells. For example, tiny robots could be engineered to deliver chemotherapy (化疗) directly to cancer instead of to the entire body.

Existing electronics are the right size, but they lack practical use. Robots that can be built small enough to enter a person’s cells would be too tiny to move on their own. Therefore, scientists want to use tiny organisms such as bacteria to act as vehicles for the robots. The bacteria will be “driven” through the bloodstream by magnetic pulses (磁脉冲). Once the bacteria are in the correct locations, the robots will be able to do their jobs. In theory, these robots will cause less damage to the body than traditional methods of delivering medicines or performing surgeries.

Nanobiotechnology has yet to be put into practice, but many people already have concerns about its use. Some people worry about the ethic (道德标准) involved with controlling live organisms—and the possible side effects for their human hosts.

1. What does the second paragraph mainly talk about?

A．The application of tiny robots.	B．The influence of tiny robots.
C．The operation of tiny robots.	D．The origin of tiny robots.

2. Which of the following could be a future benefit of nanobiotechnology?

3 . Humans have explored space beyond Earth’s atmosphere for over half a century. When astronauts explore the vast area of outer space, they need to wear high-tech spacesuits to protect them from the dangerous conditions of the universe.

A spacesuit is made up of nearly a half dozen different components(部件) and can have up to 16 layers, according to NASA. From start to finish, it can take up to four hours for an astronaut to dress up, said Cathleen Lewis, leader of international space programs. Before going on a spacewalk, astronauts must check each piece of equipment and make sure they have enough important supplies, such as oxygen and water.

The astronauts on the Artemis missions, NASA’s next program to send the first woman and the first person of color to the moon, will wear the latest spacesuit, known as xEMU. One of its main components is the cooling garment, said Richard Rhodes, leader of xEMU pressure garment development at NASA. The garment is made of tubes that circulate water around the astronaut, regulating body temperature and removing extra heat as they complete their work. Each spacesuit has a portable life-support component, which includes a water tank for the cooling garment, carbon dioxide removal system and more.

The original spacesuits used during the Apollo missions were less flexible than the ones today. Fortunately, spacesuits have come a long way since then and have a more flexible structure. On the outside of a spacesuit, there are colored stripes(条纹)unique to each suit. This is how astronauts can tell who is in each suit when out in space, Lewis said. This tried-and-true system will be used for the Artemis spacesuits.

Rhodes said the biggest challenge for the Artemis suits is making sure they are upgraded for lunar exploration. The suits need to be “light enough to support the lunar mission and strong enough to protect the astronaut while working in the very hazardous lunar environment,” he said.

1. What is the special feature of xEMU?

A．It is less flexible.	B．It can not wear easily.
C．It can protect astronauts.	D．It has a special cooling garment.

2. What are colored stripes on the outside of a spacesuit used for?

A．To test a new system.

B．To show the astronaut's nationality.

C．To distinguish who is in the spacesuit.

D．To indicate which country made the spacesuit.

3. What does the underlined word “hazardous” in the last paragraph probably mean?

A．Cold.	B．Dangerous.
C．Noisy.	D．Unstable.

4. What’s the best title of the text?

A．Brave Astronauts in NASA

B．The Development of Spacesuits

C．Spacesuits Make Space Exploration Possible

D．NASA Designs New Spacesuits for Next Mission

5 . 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。

A group of musicians from China, Germany and Switzerland joined hands in a special concert to celebrate the 100-day countdown to the Beijing 2022 Winter Olympics. The event, also known as China Media Group(CMG) China-Europe Music Festival,    1    (hold) under the theme “The World in Unity”.

It’s part of a program of special events running up to the Winter Olympics, which will begin on February 4, 2022. Thomas Bach, president of the International Olympic Committee (IOC),    2    (announce) in a video message that it would be another milestone for Beijing, the first city to host both summer and winter events.

The concert    3    (lead) by British-Swiss conductor Howard Griffiths, Swiss conductor Jean-Christophe Monnier and Chinese conductor Zhao Yuan was staged at venues(会场) in Geneva and Berlin. The concert caught wide attention as    4    included performances from world-class musicians.

Bach added, “The beautiful performances by this talented group of international artists show that inspirational moments are possible when we are dreaming together. This is    5    sport and music are all about: bringing all people together, making us dream, motivating us with    6    (beautiful) and excellence, and filling our hearts    7    joy.”

CMG President Shen Haixiong said, “Sport and music are the common language of all mankind. Artists from different countries perform wonderfully    8    (express) their sincere wishes for the success of the Beijing Winter Olympics. This    9    (true) makes me feel the friendship that is    10    (deep) than the ocean.”

7 . The world that we live in is beautiful because it’s made up of people from a diverse set of backgrounds and cultures.     1     There’s no better way than to acknowledge Global Diversity Awareness Month every October.

During this time, our multicultural world is embraced and celebrated for all of the variety and joy it brings. Can you imagine a world where everyone looks the same, has the exact same hobbies and interests, and even eats the same thing for breakfast, lunch and dinner?     2     And bringing those differences together makes us better.

To put it simply, our diversity and inclusiveness (包容性)are our biggest strengths. We’ll all profit from a more diverse, inclusive society, understanding, accommodating, even celebrating our differences, while pulling together for the common good. As such, Global Diversity Awareness Month is a great chance for us to learn more about the beliefs, values and customs of other cultures.         3    

    4     For example, we can host a multicultural movie night and watch foreign films, or listen to music from around the world or visit cultural art exhibitions. Another way we can celebrate diversity is by inviting our friends and family to dinner. Everyone can bring traditional dishes from their countries and hometowns.

There is no doubt that diversity and inclusiveness make our world a better place.     5     As Mahatma Gandhi once said, our ability to reach unity in diversity will be the beauty and the test of our civilization. Hopefully, with each passing day, we get closer and closer to that achievement.

A．There are many ways we can celebrate diversity.

B．How can we make the world a better place to live in?

C．What can possibly be a better way to celebrate that diversity?

D．Respect for world diversity is the key to bridging the differences.

E．It’s our unique differences that make the world so wonderful and interesting.

F．What’s important is that we reach out to other people and appreciate those differences.

G．In this way, we can open our mind to new ideas and ways of thinking to better our society.
