1 . Emilia Dobek traces her interest in space and the universe back to third grade when she and her father watched a blood moon — a total lunar eclipse (月食)---on the roof of their house.

Now a seven-grader at East Prairie Elementary School, Dobek recently won the national Discovery Education Beyond Challenge by designing a space station for traveling to Mars. She says that night watching the lunar eclipse launched a passion in her that has yet to run out of fuel.

So, when her teacher, Andrea Smeeton, received information about the national challenge, Smeeton said she immediately had one student in mind. “I knew she would love the challenge and that she would go way beyond in her research,” Smeeton said. “She immediately started researching bone density of astronauts and how to have sustenance on Mars.”

“My design will ensure the safety of the astronauts but also make sure their comfort is out of this world,” said Dobek. Dobck’s design calls for building the MSS or Mars Storage Station to accommodate the need for abundant supplies. She explains how her spacecraft—the Adventurer—will get into a space station before flying to the MSS to get supplies. Her design includes the SGF or SelfGrowing Farm, and she details how it would work with the elements on Mars.

Then there is physical and leisure activity for the astronauts under Dobck’s design. A. simulator (模拟器) allows astronauts to choose their exercise machine and virtual reality environment. Rooms have circular ceilings, she says, so astronauts will be able to watch downloaded shows and even see places on Earth, such as their homes. Chief among her immediate goals, she said, is to inspire with this project. want to tell other kids to follow their passions,” Dobek said. “Whatever they want to do, they should kind of just push for it. They should always try their best.”

2 . Role models are powerful. No matter what stage of life you’re at, it’s good to have someone who encourages you to be the best version of yourself. Recent winners of national commendations mean we have a wider range of possible role models.

As part of the celebration of the 70th anniversary of the founding of the People’s Republic of China (PRC), President Xi Jinping signed a presidential decree (主席令) on Sept 17 to award 42 people the Medal of the Republic, the Friendship Medal and national honorary titles, China Daily reported. Recipients come from various backgrounds, including scientists, lawmakers, educators, artists, model workers and six non-Chinese individuals. All have made big contributions to the nation’s construction and development.

Chinese scientist Tu Youyou is one of the eight who were awarded the Medal of the Republic. Tu, who won the 2015 Nobel Prize for her discovery of the malaria drug artemisinin (抗疟药物青蒿素), is the first Chinese citizen to win a Nobel Prize in Physiology or Medicine. She has saved millions of lives worldwide. She has also made important scientific innovation in traditional Chinese medicine.

“It is my dream that Chinese medicine will help us conquer life-threatening diseases worldwide and that people across the globe will enjoy its benefits,” Tu once wrote in the science journal Nature Medicine.

Tu is not the only one who has given her life to the country’s development. Nan Rendong, before his death in 2017, led the research and development of China’s Five-hundred-meter Aperture Spherical Telescope, the world’s largest radio telescope. He worked on the project for more than 20 years. The facility he designed helps humans search for extraterrestrial civilizations (外星文明) and marked a Chinese technological milestone. His contributions to Chinese astronomy earned him the title, “the people’s Scientist.”

Also receiving awards are six foreign friends who have lent their hands to assist with China’s prosperity. Former French Prime Minister Jean-Pierre Raffarin, an honoree of the Friendship Medal, is an advocate of the Belt and Road Initiative. Having worked to strengthen the friendship between French and Chinese people in the past decades, he told Xinhua that he is “sincerely pleased” with the honor. “To work for this friendship is to work for peace,” Raffarin said.

Thanks to the great efforts made by these heroic figures, we can live in a prosperous and peaceful country. Hopefully these role models can also light the way for future nation buildings.

3 . I passed my driving test at the fourth attempt. You might think that means I’m not as safe as someone who passed for the first time. But would you feel safer with no driver at all? Maybe not, and it’s for this reason that automotive firms have included driver-assist functions in their prototype (原型) driverless cars. This allows the human driver to take over if there is a problem.

Google is one manufacturer that has prototype driverless cars. These have been equipped with steering wheels and conventional controls to allow normal driving. But this is just a stage — the vision is to have fully automated cars very soon. The director of Google’s self-drive project, Chris Urmson, hopes his 11-year-old son will never have to take a driving test. To achieve that, the cars need to be on the roads in five years. He says driverless cars will greatly reduce accidents and traffic jams.

According to Chris, “about 1.2 million people are killed on the roads around the world each year. That number is equivalent to a jet falling out of the sky every day.” He thinks gradual changes to existing car designs are not enough to deal with the problem. “If we are really going to make changes to our cities and get rid of parking lots, we need self-drive cars,” he says.

Google’s prototypes have covered over a million kilometers on the road. They have also had to deal with unexpected situations, such as a child driving a toy car in the road, and a woman in an electric wheelchair chasing a duck. In each case, they reacted safely.

Some are not convinced. Seven Beiker of Stanford University thinks driverless cars will still need human input in extreme circumstances. He also worries that people may forget how to operate their vehicles if they do not do it regularly. “I guess I shouldn’t throw away my driver’s license just yet,” he says.

1. What can be known about driverless cars?

A．They are fitted with newly-developed steering wheels.

B．They include functions managed by human drivers.

C．They need traditional controls to avoid traffic jams.

D．They will be purchased on the market in five years.

2. What can we learn from what Chris said?

A．Chris believes that there is a possibility of a jet crashing per day.

B．About 1.2 million people are killed around the world each year.

C．Changing current car designs alone cannot prevent all traffic deaths.

D．Driverless cars cannot deal with extreme circumstances without human help.

3. What’s the attitude of Seven Beiker towards driverless cars?

A．Approving.	B．Cautious.
C．Neutral.	D．Hopeful.

4. What does the passage mainly talk about?

A．Why we need driverless cars in the near future.

B．How to control a driverless car without a driver’s license.

C．Differences between driverless cars and conventional ones.

D．A brief introduction of driverless cars and some opinions on them.

4 . New York is an overwhelming city to visit with children. Went follows is carefully collected advice from New Yorkers on how to cover the city right.

Tenement Museum

The Tenement Museum on the Lower East Side offers a fantastic glimpse into urban family life. Guided tours reveal the daily routines of generations of Irish, Jewish and Italian immigrants who made their mark then quickly moved up and out. Pick up a copy of “All-of-a-Kind Family” or a vintage toy in the museum shop, one of the city’s best.

MoMa Museum

MoMa Museum does an excellent job making modern and contemporary art accessible to children as young as 4. On weekend mornings, guided tours are divided into age-appropriate groups in which children can observe a number of works and draw; later they gain free admittance to the entire museum. The cafeteria is both grown-up and child-friendly, and there’s an art laboratory with hands-on activities and even an audio guide for young people.

Intrepid Sea, Air and Space Museum

The most significant in the museum is the Space Shuttle Pavilion, which is scheduled to reopen in July, showcasing the Enterprise, NASA’s first space shuttle, which arrived last year. The U.S.S Intrepid, a World War II-era aircraft carrier, is worthwhile in itself. While the complex suffered damage during Hurricane Sandy, most of its facilities are once again shipshape. Families may want to consider Operation Slumber, which allows for overnight visits with special activities for children 6 and older.

Children’s Museum of the Arts

All the artwork here is made by children, and visitors can make their own (bonus: you don’t have to clean up). An area for younger children includes sand, Play-Doh and guided music activities. Children go berserk for the Ball Pond, a closed-in area of oversize balls. Is it experiential art? An installation? Children need not bother with such imponderables.

1. Which of the following museums offer free admission?

A．Tenement Museum.	B．MoMa Museum.
C．Intrepid Sea, Air and Space Museum.	D．Children’s Museum of Arts.

2. How is Children’s Museum of the Arts different from the other three museums?

A．It provides activities for children of different ages.	B．It exhibits a lot of artwork.
C．Its artwork is all created by children.	D．It used to be damaged in the Hurrican Sandy.

3. What do the four museums have in common?

A．They are all children-friendly.

B．They all show visitors contemporary artwork.

C．They can offer visitors activities to take part in.

D．They are all suitable for children over 4 years old.

5 . I was working as a lifeguard at Tower 15 on Newport and two blocks to my right was another guard named Mike, working at Tower 17.

6 . Over a million children have developed some form of intellectual （智力） disability over the past two decades after being exposed to chemicals including flame retardants, pesticides, lead, and mercury, a study has revealed.

The study focused on the four chemicals, which can be crossed from a mother to her unborn baby through the placenta（胎盘）and cause neurodevelopmental damage. The researchers looked at data from past studies, including blood samples taken from women of childbearing age and 5-year-olds.

Over the period, flame retardants, resulted in 738,860 cases of intellectual disability and an estimated 162 million lost IQ （智商）points, followed by lead at 330,684 cases, pesticides at 111,830, and mercury at 8,860. In recent years, pesticides and flame retardants have overtaken lead and mercury as the chemicals responsible for the biggest loss of IQ among children.

The researchers believe this is due to regulations cutting down the use of these chemicals. For instance, lead has been banned from gasoline, paint and drinking water systems in the U.S. and plants are not allowed to pump out mercury.

The researchers acknowledged limitations to their study, including that the exposure-response relationships might not relate to all populations. Positively, they found a huge drop in the estimated loss of IQ points among children.

Lead researcher Abigail Gaylord, commented: "Our findings suggest that our efforts to reduce exposure to heavy metals are paying off, but that harmful exposures in general continue to represent a terrible risk to people's physical, mental, and economic health. "Unfortunately, the minimal policies in place to remove pesticides and flame retardants are clearly not enough," she said.

She also added. Frequently opening windows to let persistent chemicals found in furniture   electronics, and carpeting escape, and eating certified organic produce can educe exposure to these harmful things"

7 . The first time I went hunting wild geese with my father, I couldn't catch them no matter how hard I tried. Every time I tried to approach them, _______ the wild geese started flying away before I could get close. It _______ me a lot and I turned to my father for help.
