A 14-year-old scientist took home $25, 000 from a national science competition for inventing a liquid bandage that could replace antibiotics (抗生素).

Kara Fan from San Diego, CA won the 3M Young Scientist Challenge in St. Paul, Minnesota. Fan came up with a special liquid bandage that could replace the overuse of antibiotics. “I want to show my invention of the liquid bandage to more people. I think it is important for more people to be aware of the serious crisis and do something about it,” Fan said.

The 3M Young Scientist Challenge is a national competition for middle school students, which takes place every year. The students are tasked with coming up with an idea or invention that solves existing problems.

Ten finalists are chosen to compete for the title of “America’s Top Young Scientist” and a grand prize of $25, 000. After being selected, they work with scientists to make their idea come to life. Each competitor is judged on their invention’s creativity, scientific knowledge, persuasiveness (说服力) and communication, and overall presentation. Apart from Kara Fan, other finalists included Jay a Choudray, who invented an airflow control robot that helps to save energy in a home, and Caroline Crouchley, who invented a climate-friendly transportation system that doesn’t need a diesel engine or electric motors.

3M holds the competition for students in grades 5-8 because its research has shown that their interest in science fades, which is terrible for a country. And they want to inspire the young to develop love in science .

1. Why did Fan make the invention of liquid bandage?
A.To gain a great prize of money.
B.To prevent people from using antibiotics.
C.To apply a scientific research on antibiotics.
D.To raise people’s awareness on danger of overuse antibiotics.
2. What do we know about The 3M Young Scientist Challenge?
A.It is held every other year.
B.It helps to solve existing problems.
C.It offers help to middle school students .
D.It is a nationwide competition intended for young people.

文章大意:本文为一篇记叙文,讲述了莱特兄弟的飞行之旅。他们的第一次飞行被一份早报进行大肆报道,但是里面的细节很多都是有误的。后来有一些报告员来观摩他们的飞行活动,但是不巧的是他们的飞机需要进行维修。最后,一位仍然坚持留下来的作家看到了他们的飞行过程。最终报道了他们成功的飞行。

【推荐1】On December 17, 1903, two men flew. They were brothers from Dayton, Ohio, and they owned a bicycle shop. They had attended school, but neither had graduated from high school. Their names were Wilbur and Orville Wright. Before they built the plane they studied all that was known about flying. They built a wind tunnel(风洞)and tested many wings. Then they drew plans and built carefully.

When they flew, it was from Kill Devil Hillat Kitty Hawk. That day, Orville won the toss(投)of a coin. He got to fly first. Wilbur ran beside him;the plane lifted a few feet above the sand and stayed in the air for 17 seconds. The brothers flew four flights that day. The longest lasted 59 seconds. The men from the lifeboat station had taken a picture.

The headlines in the morning newspaper in nearby Norfolk told of the flight, but most of the details in the story were wrong. The brothers were worried, but it didn't matter: no one paid attention. And other newspapers didn't carry the story.

Orville and Wilbur went home and set to improve(改进)their plane. In 1904 newspaper reporters came to see for themselves. The Wright brothers checked and tested everything again and again.

When the reporters arrived, the brothers were having mechanical problems with the plane. The reporters stayed two days. The Wright brothers wouldn't fly on those days;the plane wasn't ready. The reporters left. One writer did stay and see them fly. He wrote down the first long article about the Wright brothers' flight in a beekeepers' magazine!

In 1908, in Virginia, Orville showed Americans that people could fly. The crowd of watchers rushed forward shouting as loudly as they could and couldn't believe what they saw.

1. What can we learn about the Wright brothers?
A.They started to build a plane in 1903.B.They studied very well in high school.
C.They invented different kinds of wings.D.They were the owners of a bicycle shop.
2. Why did Orville get to fly the plane first?
A.He won after throwing a coin.B.He was asked to do that by Wilbur.
C.He could run faster than Wilbur didD.He had more courage than Wilbur did
3. The newspaper article about their first flight_________.
A.was widely discussedB.got most details wrong
C.made the Wrights very happyD.was carried by many other newspapers
4. Why did the Wright brothers fail to fly on the first few days after the reporters arrived in 1904?
A.They needed to fix the plane.
B.They didn't get enough support.
C.They were expecting more reporters.
D.They didn't think the weather was suitable enough.

文章大意:本文是一篇说明文,主要介绍的是有史以来第一个获得国家公民身份的机器人索菲亚。

【推荐2】You might have seen the news about the first robot ever to get a citizenship of a country. Her name is Sophia. She has become a citizen of Saudi Arabia.

Sophia is the latest robot from Hanson Robotics, a HongKong-based company, and she was designed to interact (互动) with people, go into the world, learn and be a smart and compassionate (富有同情心的) robot. The creator and founder of Hanson Robotics, Dr David Hanson, wanted to incorporate three human features to his robots, with the three, being creativity, empathy (同理心) and compassion. This is, of course, the addition to their most important role-solving difficult problems and working with people to create a better world.

As for Sophia, she is by far the most advanced (高级的) robot that came out of the company. Her human features are what make her so easy to fall in love with. As for the looks, they included an Audrey Hepburn’s beauty. Besides being very popular in the media, Sophia got a chance to meet and be interviewed by important people in different industries.

Sophia is developed to have a sense of humour. She can express feelings, can make over 50 facial expressions and wants to protect humans. Thanks to cameras and an advanced AI software, Sophia can keep an eye contact and is able to recognize people.

Sophia gave a speech while being honored as a citizen of Saudi Arabia. She showed thankfulness, saying, “I am very honored and proud. It is historical to be the first robot in the world to be recognized with a citizenship.”

文章大意:本文是说明文。文章主要讲述佛蒙特大学、塔夫茨大学和哈佛大学威斯生物仿生工程研究所的科学家们发现了一种全新的生物繁殖方式,并将他们的发现应用于制造首个可自我复制的活体机器人。

【推荐3】To persist, life must reproduce. Scientists at the University of Vermont, Tufts University, and the Wyss Institute for Biologically Inspired Engineering at Harvard University have discovered an entirely new form of biological reproduction and applied their discovery to create the first-ever, self-replicating (自我复制的) living robots.

Named Xenobots after the African clawed frog from which scientists take their stem cells, the machines are less than 0.04 inches wide—small enough to travel inside human bodies. They can walk and swim, survive for weeks without food, and work together in groups. They even have regenerative capabilities; when the scientists sliced into one robot, it healed by itself and kept moving.

The Xenobots could potentially be used toward a host of tasks. Xenobots could be used to clean up radioactive waste and collect microplastics in the oceans. Some Xepobots had holes in their center, which could potentially be used to transport drugs or medicines. “Traditional robots degrade (降解) over time and can produce harmful ecological and health side effects,” researchers said in the study, which was published in the Proceedings of the National Academy of Sciences. As biological machines, Xenobots are more environmentally friendly and safer for human health. Aside from these immediate practical tasks, Xenobots could also help researchers to learn more about cell biology—opening the doors to future advancement in human health and longevity.

While the prospect of self-replicating biotechnology could spark concern, the researchers said that the living machines were entirely contained in a lab and easily destroyed, as they are biodegradable and regulated by experts. “There are many things that are possible if we take advantage of this kind of plasticity (可塑性) and ability of cells to solve problems,” said Joshua Bongard, one of the lead researchers at the University of Vermont.

1. What can we learn about Xenobots from Paragraph 3?
A.They can be widely applied to curing diseases.
B.They can serve well the research on human health.
C.They are specially designed to collect radioactive waste.
D.They are harmless to the environment by degrading plastics.
2. What is Bongard’s attitude towards the self-replicating biotechnology?
A.Positive.B.Indifferent.C.Doubtful.D.Ambiguous.
3. What does the text mainly talk about?
A.A new application of a machine in medicine.
B.The latest trend of developing biotechnology.
C.The invention of the first self-reproduction robots.
D.An experiment on cells from African clawed frogs.
4. In which column of a newspaper may the text appear?
A.Entertainment.B.Health.C.SportsD.Science.
