Fancy your own satellite? Arizona State University is working towards making this a reality with its SunCube FemtoSat project. Smaller than a standard CubeSat, the low-cast student-designed spacecraft is aimed at providing greater access to space for scientists and hobbyists alike.
Assistant professor Jekan Thanga and a team of students have been developing the SunCube FemtoSat for the past two years. The small 3×3×3cm cube weighs in at just 35g and a longer (3×3×9cm, 100g) model has also been designed, which includes storage space.
Each SunCube FemtoSat has its own communication, data collection and propulsion (推进) systems and is powered by solar panels. It is made of off-the-shelf parts that are available in shops, and the energy-efficient solar panels are cut from scrap (碎片), which makes it save energy, sold at a discount by manufacturers. “With a spacecraft of this size, any university can do it,” says Thanga. “That’s part of our major goal—space discovery for everybody.”
The team says that while launching your own satellite would usually cost between US $ 60,000-70,000 per kilo, it would only cost $ 1,000 to send a SunCube FemtoSat to the International Space Station, and $ 3,000 to send it into low earth orbit. Leaving the earth’s gravity would cost an estimated $ 27,000.
The FemtoSat would be packed with a “jack in the box” style system that matches standard CubeSat sizes (around 10 cubic cm), simplifying the process of getting the tiny satellite into orbit. NASA has sent 30 CubeSats into space over the last years, with another 50 awaiting launch.
Thanga and his staff view the FemtoSat as a starting point for scientists and students, and even hope the device could be bought on the website like Amazon one day. Thanga imagines developing four main applications for the device, including hands-on testing experiences for students, and artificial gravity experiments. In addition, groups of SunCube FemtoSats could eventually be able to do the job of larger spacecraft at a vastly discounted cost.
1.What is the major goal of the SunCube FemtoSat project?
A.To act on teaching in outer space. B.To provide access to spacecraft design.
C.To help carry out a classroom experiment. D.To help average individuals explore space.
2.What is special about SunCube FemtoSats?
A.They are of the same size. B.They are energy-efficient.
C.They are mainly designed for lab use. D.They are mainly used to collect information.
3.What does Thanga expect of SunCube FemtoSats?
A.They’ll be available online. B.They’ll be provided for free.
C.They’ll match the size of CubeSats. D.They’ll be sent into space with CubeSats.
4.What can be the best title for the text?
A.FemtoSats Will Rule Space B.Your Own Satellite Is Coming
C.Going into Space Has Been Afforable D.You can Design Your Own Spacecraft

Juili Kale was looking forward to receiving her master's degree at Arizona State University. She planned to invite her family living in India to the United States for her graduation ceremony. But then, in March, the coronavirus pandemic ended those plans as schools nationwide closed to stop the spread. Kale's dream of spending time with family members on her big day came crashing down. Yet the graduation ceremony is taking place—just not as she expected.
University officials have turned to robots so Arizona State graduates and their families can take part in the event online. Cameras recorded images of Kale and about 140 other graduates online this month. They were wearing robes and mortar board caps. They took turns moving a robot at the university that held an eye-level display showing their face. With the help of the robot, they stepped forward to receive their diplomas and take pictures. The robots are from Double Robotics, a company based in Burlingame, California. Before the health crisis, they had been used to help people attend funerals and even marriage ceremonies without traveling.
Sanjeev Khagram is dean of Arizona State's Thunderbird School of Global Management. He said that the video- a ''bittersweet'' experience—was recorded and produced over two days. It may not have been ideal for the students. Khagram admitted. '' But, we want to show that we did everything that we could to celebrate them. When the crisis is over, the class of 2020 can do a real-life walk at any future graduation ceremony they choose. ''
Kale planned to throw a ''watch party'' with her husband at home and her family in India.
Getting used to the online experience was easy for Nancy Sierras Morales. ''We have been able to adapt very quickly because we are used to being on a computer and on the phone almost like 24/7, '' the 22-year-old said. She said that, while it is not the best, it is ''cool...to be like the first class ever to do this''.
''I'm disappointed.'' said 41-year-old Douglas Northcott. He is graduating with a master's degree in applied leadership and management. He called the online event with robots ''creative''. But he looked forward to the real thing. ''And if anything, that makes it better , in that it is spread over two times rather than one. ''
1.What had the robots mainly been used for before the graduation ceremony?
A.Saving travelling for people to attend ceremonies like weddings.
B.Hosting all kinds of ceremonies for people unable to travel.
C.Helping professors with their teaching plans in universities.
D.Amusing people during their travelling to funerals.
2.According to the text, ________ made a fast adjustment to the new situation.
A.Juili Kale B.Sanjeev Khagram
C.Nancy Sierras Morales D.Douglas Northcott
3.According to Sanjeev Khagram, to have a real graduation ceremony, the 2020 graduates can ________.
A.throw an online ''watch party''
B.attend any future graduation ceremony
C.hold another real one by themselves
D.do everything they can to celebrate
4.What is the best title for the text?
A.A disappointing graduation ceremony
B.A graduation ceremony with the help of robots
C.A multifunctional robot from Double Robotics
D.A special experience of students in the health crisis

Lindha was a student at Kansas State University. She is here to tell us about her time in Kansas in the city of Manhattan.
What were the best things about it?
Manhattan has a great university feel to it. I loved going to the football games. We would spend the whole day tailgating (开车尾派对) outside the stadium, drinking beer and having a big barbecue.
What do you think of the people there?
People from Kansas are so friendly. However, I'd say that many Kansans are very sheltered and don't pay much attention to life outside the US. But as the grandma of my Kansan friend might say, “We're still sweet as pie.”
What were the worst things about being there?
It's very difficult to get around Kansas without a car. Everything's so spread out and there isn't really a public transportation system.
What was the funniest thing that happened while you were there?
I remember one trip I took with my friend to her grandparents' house. They had horses and asked me if I wanted to go for a ride. I had never ridden a horse before but I decided to have a try. I hopped (跳上) on and everything was fine for a minute. But then the horse went crazy. It started bucking (猛然弯背跃起) and making these crazy noises. I thought I was going to die. My friend eventually calmed the horse down but not before I had destroyed an entire section of the fence. I thought they would be mad but they were just in shock — they couldn't believe I had stayed on the horse for that long.
Did you have any other problems?
I'm Swedish, but my English is pretty good because my dad's English. But it took a little while to get used to the accent. The people from the cities don't have a strong accent, but the people from the country are hard to understand sometimes. You also have to be careful with the weather. In the winter it was absolutely freezing, and during the summer it was so hot I thought I might die. Of course, they have heating and air conditioning everywhere.
1.What's Lindha's impression about people in Kansas?
A. They are kind but unhappy.
B. They are nice but isolated.
C. They are patient and amusing.
D. They are honest and generous.
2.What do we know about Lindha's horse riding experience?
A. She fell off the horse's back.
B. She finally got the horse under control.
C. She was brave but destroyed part of a fence.
D. She had a wonderful and unforgettable experience.
3.We learn from the text that Lindha _____.
A. doesn't like the weather in Kansas
B. speaks English with a Swedish accent
C. speaks highly of the transportation system in Kansas
D. doesn't like the school life in Kansas State University

Two people have died after two separate university shootings in Texas and Arizona, just hours apart. One person was killed and three injured in the first shooting at Northern Arizona University early on Friday. Later that morning a shooting at a student complex near Texas Southern University left one person dead.
In Arizona, police named the gunman there as Steven Jones, an 18-year-old first year student at Northern Arizona University.Mr. Jones told police he was approached by a group of men and attacked. He fled, produced a gun from his pocket and opened fire when the men caught up with him, Arizona police said. Witnesses told police that the victims were unarmed.
The second shooting in Texas happened later on Friday morning at the University Courtyard Apartments on the edge of the Houston campus. One student was killed, a freshman at the school, the university confirmed, and another person was wounded. Two people have been arrested as suspects and a third is still at large, said Houston police spokeswoman Jodi Silva.
The attacks came as President Barack Obama visited families of victims of a college shooting in Oregon. On arriving in Oregon, he was jeered(嘲笑) by gun rights activists who oppose calls he made for tougher gun laws after nine people were killed at Umpqua Community College, Roseburg, last week.
After a private meeting with families, Mr Obama said he had "strong feelings" about gun control, adding: "We are going to have to come together as a country to see how we can prevent these issues from taking place.”
On the edge of this little American town, a few hundred protestors gathered to tell their president he was not welcome. Many were openly carrying handguns to hammer home their message. The demonstrators blamed the shooting here last week on two things: a failure to treat mental health problems and the designation of Umpqua Community College as a gun-free zone. Many of those we spoke to said they had travelled to Roseburg from elsewhere in Oregon to make their voices hear. The hostility to the Democratic president here in Republican rural Oregon was not just political, it was personal.
1.How many people were dead in these two recent university shootings?
A. One.
B. Two.
C. Three.
D. Four.
2.Which of the following is right about the Northern Arizona University shooting?
A. The gunman was about to graduate.
B. It was the victims who started the fight.
C. The gunman shot the victims out of hatrd.
D. The victims attacked the gunman with knives.
3.Mr. Obama probably agreed that ____________.
A. gun control is too strict in most parts of America, especially in universities
B. designation of Umpqua community college as a gun-free zone is a wrong decision
C. Americans should be united to prevent criminal shooting from happening so frequently
D. A failure to treat mental health problems caused the shooting at Umpqua Community College
4.The underlined words in the last paragraph is closest in meaning to ____________.
A. emphasize
B. digest
C. commit
D. respond
