Eater of Natural Disasters
My invention cansave your home by sucking up all-natural disasters. The government will not own this machine, but by you so there will be no taxes on it. Order Now! The Eater of Natural Disasters will run on renewable batteries. It will cost 50 dollars to make and I will sell it for just $ 75.
Created by Matthew Szekeresh —Mt.WashingtonElementary, 5th Grade.
Pick-up-Pollution Bomb
My invention is called the Pick-up-Pollution Bomb. It will just pick up pollution and it won't hurt anything else like people, animals, property, playgrounds, and parks. The reason why I made it is that I think there is too much pollution on the Earth. It sells for $100 apiece, and if you buy this now, I will send you another one for free.

While space travel still gets lot of attention, not enough attention has been paid to the exploration of oceans, about which we know much less than the dark side of the moon.
Ninety percent of the ocean floor has not even been recorded and while we have been to the moon, the technology to explore the ocean's floors is still being developed. For example, a permanent partially-underwater sea exploration station, called the Sea Orbiter, is currently in development.
The oceans play a major role in controlling our climate. But we have not learned yet how to use them to cool us off rather than contribute to our overheating. Ocean organisms are said to hold the promise of cures for a wide of the unique eyes of skate (ray fish) led to advances in conquering blindness, the horseshoe crab was important in developing a test for bacterial pollution, and sea urchins helped in the development of test-tube fertilization(人工授精). The toadfish's' ability to regenerate its central nervous system is of much interest to neuroscientists. A recent Japanese study concluded that the drug Eribulin, which was taken from sea sponges, is effective in fighting with breast, colon, and Urinary cancer.
Given the approaching crisis of water insufficiency, we badly need to improve current methods, of desalinating(淡化) ocean water and make them more efficient and less costly. By 2025, 1.8 billion people are expected to suffer from severe water shortage, with that number jumping to 3. 9 billion by 2050-well over a third of the entire global population.
If the oceansdo not make your heart go beating faster, how about engineering a bacterium that eats carbon dioxide — and thus helps protect the world from overheating — and produces fuel which will allow us to drive our cars and machines, without oil? I cannot find any evidence that people young or old, Americans or citizens of other nations would be less impressed or less inspired with such a breakthrough than with one more set of photos of a faraway galaxy or a whole Milky Way full of stars.
4. What does the author think about the ocean exploration?
A. It is equal to the space exploration.
B. It is well developed.
C. It deserves more attention and devotion.
D. It is beyond our knowledge.
5. What technology has been developed to make use of the oceans?
A. Curing human diseases with ocean organisms.
B. Preventing the world getting warmer.
C. Mapping the global ocean floor.
D. Removing salt from sea water.
6. What does the author imply in the last paragraph?
A. The temperature rise will be overcome by a bacterium.
B. Solving the existing problems is more significant.
C. The space exploration is worth the efforts.
D. The ocean exploration is not inspiring.
7. What is the best title of the passage?
A. Oceans, the Last Hope.
B. Oceans, the Hidden Treasure.
C. Space, the Final Frontier.
D. Space, the Faraway Dream.
C
Avi Loeb, a scientist, believes that we are not alone in the universe. The belief fits withLoeb's alien spaceship theory that at least one alien spaceship might be flying over the orbit of Jupiter, which won the international attention last year.
Astronomers inHawaiifound the first known interstellar object in late 2017. It was a bit of light moving so fast past the sun that it could only have come from another star. Almost every astronomer on the planet was trying to figure out how the object, called “Oumuamua” got to our far-away part of the Milky way galaxy. “One possibility is that ‘Oumuamua’ is debris from an advanced technological equipment,” Loeb said. “Technology comes from another solar system just showed up at our door. ”
“‘Oumuamua’ is not an alien spaceship,” Paul Sutter, another scientist wrote. He suggested Loeb was seeking publicity. Most scientists think “Oumuamua” is some sort of rock. They think it could be an icy wandering comet.
Loeb says that “Oumuamua's” behavior means it can't be a block of rock shaped like a long photo. He thinks it's more likely an object that's very long and thin, perhaps like a long pancake or a ship's sail. Loeb says that if someone shows him evidence thatcontradictshis beliefs, he will immediately give in.
Loeb believes himself a truth-teller and risk-taker in an age of very safe, too-quiet scientists. “The worst thing that can happen to me is that I would be relieved of my management duties, and that would give me even more
time to focus on science,” Loeb says. He said he wouldn't mind giving up all the titles he had and returning to the Israeli farming village where he grew up.
8. What does Loeb say about “Oumuamua”?
A. It is an icy comet.
B. It looks like a long photo.
C. It is actually some sort of rock.
D. It may come from another alien civilization.
9. What does the underlined word “contradicts” in paragraph 4 probably mean?
A.Goes against.
B. Relies on.
C. Turns to.
D. Searches for.
10. What do you think of Loeb?
A. He is foolish.
B. He is unsatisfied with his titles.
C. He is a firm believer in scientific truth.
D. He is uncertain about his career future.
11. What's the best title for the text?
A. Have Aliens Paid a Visit in Spaceships?
B. Do We Really Know about Space Theory?
C. Scientists Are Working on High Technology
D. Astronomers Are Encouraging Space Travel
D
NASA has flown an aircraft on another planet for the first time. On Monday, April 19, Ingenuity, a 1. 8-kilogram drone (无人机) helicopter, took off from the surface of Mars, flew up about threemeters, then hovered for 40 seconds and took photos above with one of its two cameras. The historic moment was livestreamed on YouTube. “We can now say that human beings have flown a drone helicopter on another planet,” said MiMi Aung, the Ingenuity Mars Helicopter project manager at NASA's Jet Propulsion Laboratory, at a press conference. “We, together, flew at Mars, and we, together, now have our Wright brothers moment,” she added, referring to the first powered airplane flight on Earth in 1903.
The details: The flight was a significant technical challenge, thanks to Mars' s bone-chilling temperatures (nights can drop down to -130 °F / -90 °C) and its incredibly thin atmosphere — just 1% the density of Earth' s. That meant Ingenuity had to be light, with rotor blades (螺旋桨) that were bigger and faster than would be needed to achieve liftoff on Earth (although the gravity on Mars, which is only about one-third of Earth's, worked in its favor). The flight had originally been scheduled to take place on April 11 but was delayed by software issues.
Why it's significant: Beyond being a significantmilestonefor Mars exploration, the flight will also pave the way for engineers to think about new ways to explore other planets. Future drone helicopters could help astronauts by scoping out locations, exploring inaccessible areas, and capturing images. Ingenuity will also help inform the design of Dragonfly, a car-size drone that NASA is planning to send to Saturn's moon Titan in 2027.
What's next: In the next few weeks, Ingenuity will conduct four more flights, each lasting up to 90 seconds. Each one is designed to further push the limits of Ingenuity's capabilities. Ingenuity is only designed to last for 30 Martian days, and is expected to stop functioning around
May 4. Its final resting place will be in the Jezero Crater as NASA moves on to the main focus of its mission: Getting the Perseverance rover (毅力号火星探测器) to study Mars for evidence of life.
12. Why does MiMi Aung mention Wright brothers?
A. To honor the historic contribution of Wright brothers.
B. To make a comparison between Wright brothers and herself.
C. To highlight the importance of Ingenuity's Martian exploration.
D. To remind the public of the first powered airplane flight on Earth.
13. What caused challenges for Ingenuity designers?
A. The delay of software tests.
B. The force of gravity on Mars.
C. Mars's temperatures and atmosphere.
D. Technical difficulty in liftoff on Earth.
14. What does the underlined word “milestone” in Paragraph 3 probably mean?
A. A great victory.
B. A difficult task.
C. A roadside stone.
D. A historic event.
15. Which of the following can be a suitable title for the text?
A. Mars Drone Helicopter Makes Historic First Flight
B. Modern Wright Brothers Moment: Mars Exploration
C. First Drone Helicopter Spots Evidence of Life on Mars
D. Ingenuity: Mars Drone Flies to Take Incredible Pictures
