Arthur Lih of Massapequa sold his first LifeVac，a device to help save people's life，to a fire department about 18 months ago，when the Jericho Fire Department purchased 21 of the devices.Now about 10 Long Island fire departments have purchased Lih's invention，which is designed to draw foreign objects from the throats of choking victims when procedures such as the Heimlich Maneuver （海姆立克急救法） don't work.He has sold about 5，000 LifeVac devices in the United States and abroad since the device went on the market in August 2014.
The Freeport Fire Department is one of Lih's clients.It bought about 25 LifeVac devices to put on trucks，as well as in chiefs' vehicles，said Ray Maguire，the department's executive director. "It's an extra tool in the toolbox，" Maguire said. "I'd be surprised if anyone who sees it doesn't purchase jye.ai.It's that tool you may only need once，but it's the tool you really want in case you need jye.ai.It's affordable.I have it in my car.I have one at home，too."
Dr.Lee Smith at Northwell Health said that if a choking victim can't breathe，he or she becomes a candidate for the Heimlich.If the Heimlich doesn't work，the victim would probably lose consciousness because of a lack of oxygen.
A challenge for any new medical device is convincing potential users that it works and is safe.In tests，the LifeVac successfully removed an obstruction （阻塞物） from the throat of a dead human body on the first try 49 out of 50 times，according to an August research article in the American Journal of Emergency Medicine.
Lih invented the product in his garage，inspired after he went with a friend to a hospital while the friend's mother was going through tests.The friend said the last time he was there，a 7-year-old child had choked to death on a grape.
（1）What's the function of the LifeVac device？ BB
A．To put out the fire.
B．To remove foreign objects.
C．To design procedures.
D．To treat victims' throats.
（2）What does Paragraph 2 mainly tell us about the invention？ BB

2．Nuclear bombs.That's the go-to answer for incoming space objects like asteroids（小行星） and comets，as far as Hollywood is concerned.Movies like Deep Impact and Armageddon rely on nuclear weapons，delivered by stars like Bruce Willis，to save the world and deliver the drama.
But planetary defense experts say in reality，if astronomers spotted a dangerous incoming space rock，the safest and best answer might be something more subtle，like simply pushing it off course by crashing it with a small spacecraft.
That's just what NASA did on Monday evening，when a spacecraft headed straight into an asteroid called Dimorphous，which is around 7 million miles away and poses no threat to Earth.It's about 525 feel across and orbits another larger asteroid.
In images streamed as the impact neared，the egg-shaped asteroid grew in size from a little spot on screen to have its full rocky surface come quickly into focus before the signal went dead as the craft hit right on target.
Events happened exactly as engineers had planned，they said，with nothing going wrong. "As far as we can tell，our first planetary defense test was a success，" said Elena Adams，the mission systems engineer，who added that scientists looked on with "both terror and joy" as the spacecraft neared its final destination.
The impact was the peak of NASA's Double Asteroid Redirection Test （DART） ，a 7-year and more than ﹩300 million effort which launched a space vehicle in November of 2021 to perform humanity's first ever test of planetary defense technology.It will be about two months，scientists said，before they will be able to determine if the impact was enough to drive the asteroid slightly off course，probably shortening its original orbit.
NASA plans to launch an asteroid-hunting space telescope named NEO Surveyor in 2026. "We've tacked lots of space rocks，especially the larger ones that could cause extinction-level events.Thankfully，none currently threaten Earth.But many asteroids the size of Dimorphous haven't yet been discovered，and those could potentially take out a city if they came crashing down." explains Lindley Johnson，NASA's Planetary Defense Officer.
（1）How did scientists know the craft hit the asteroid successfully？
A．The signal from the craft was lost as it hit the target.
B．They recorded the whole process with a telescope.
C．The little spot on the screen suddenly disappeared.
D．They monitored the craft with satellites in space.
（2）What is the purpose of launching the spacecraft？
A．To search for evidence of alien life.
B．To end the asteroid's threat to Earth.
C．To save the world and deliver a drama.
D．To test technology for defending Earth.
（3）What can be inferred about Dimorphous？
A．It is a dangerous incoming space rock.
B．It is an egg-shaped asteroid around Earth.
C．It may orbit the same asteroid after the hit.
D．It is expected to blow up after the impact.
（4）Which statement will Lindley Johnson probably agree with？
A．Asteroids are equally destructive whatever the size.
B．NEO Surveyor is aimed to track smaller asteroids.
C．Larger asteroids will no longer threaten Earth.
D．NASA is responsible for the safety of Earth.發(fā)布：2024/12/11 2:0:1組卷：6引用：4難度：0.5 -
