The world is not coming to an end on December 21, 2012, the US space agency insisted Monday in a rare campaign to dispel widespread rumors fueled by the Internet and a new Hollywood movie．

The latest big screen offering from Sony Picture, 2012, arrives in theaters on Friday, with a 200-million-dollar production about the end of the world supposedly based on myths backed by the Mayan calendar．It is claimed that the end of time will come as a Planet X---or Nibiru---heads toward or collides with the Earth．

Some websites accuse NASA of hiding the truth on the planet’s existence, but the US space agency condemned such stories as an “Internet hoax”．“There is no factual basis for these claims,” NASA said in a question-and-anwser posting on this website．“If such a collision were real, astronomers would have been tracking it for at least the past decade, and it would be visible by now to the naked eye．Obviously, it does not exist．Credible scientists worldwide know of no threat associated with 2012,” it insisted．“After all, our planet has been getting along just well for more than four billion years,” added NASA．

There is another planet, Eris, floating in space．But the small planet similar to Pluto will remain safely fixed in the outer solar system and it can come no closer than four billion miles to the Earth, according to NASA．

Earlier theories set the disaster for May 2003, but when nothing happened the date was moved forward to the winter in 2012 to coincide with the end of a cycle of the ancient Mayan calendar．

NASA insisted the Mayan calendar in fact does not end on December 21, 2012, as another period begins immediately afterward．

And even if the planets were to line up as some have forecast, the effect on our planet would be “negligible（unimportant）”, NASA said．

“And while comets and asteroids （小行星） have always hit the Earth, big hits are very rare,” NASA noted．The last major impact was believed to be 65 million years ago, resulting in the end of dinosaurs．

“We have already determined that there are no threatening asteroids as large as the one that killed the dinosaurs,” the space agency said．

1.______ played a key role in the spread of the rumors．

A．A new book                       B．The Internet and a new Hollywood movie

C．NASA                             D．An Indian calendar

2.We can infer that ______．

A．people didn’t take the rumor seriously

B．Planet X --- or Nibiru does exist

C．astronomers have been tracking Planet X for over ten years

D．the rumor caused a panic among some people

3.NASA thinks that Eris ______．

A．might have a threat to the Earth B．doesn’t have any threat to the Earth

C．is too far away to be visible    D．is similar to our planet, where life might exist

4.Which of the following is the best title?

A．New Hollywood movie 2012

B．December 21, 2012, Not the end of the world

Dec 21st 2018

On December 19th Gatwick airport, Britain’s second-biggest, was forced to close due to several sightings of drones（无人机）flying near its runways. The airport only reopened on the morning of December 21st. 　 ①　 .

The potential for an incident of this scale has been recognized for some years now. The falling price of small drones in recent years has resulted in the number flying dangerously near aircraft to rise sharply. 　 ②　 .

This is a threat that the authorities have to take seriously. Recent research suggests that small unmanned aerial vehicles (UAVs) can be much more damaging than birds — a surprisingly common cause of aircraft crashes — at the same impact speed, even if they are a similar weight. The researchers found that the drones’ rigid and dense materials—such as metal, plastic and lithium batteries—can put aero planes at much greater risk than a bird carcass（动物尸体）. If a drone were to hit an aircraft’s fan blades when it is operating at its highest speed, the blades could break and power to the engine could be lost.

③　 . But it also underlined the potential for destruction that drones afford. The British police do not think that terrorism was the motivation behind the latest incident at Gatwick. According to the Daily Telegraph, a British newspaper, environmental activists are suspected of being behind the attack, which has happened before.

As attention turns to what can be done to prevent a repeat, two solutions stand out. The first is regulation. Regulators in America and Britain already ban drones from flying too close to airports. America has introduced a compulsory registration scheme for drones and Britain plans to follow suit.

But as the chaos at Gatwick shows, even serious punishments will not stop those intending to cause harm deliberately. 　 ④　 . Technology is the second, and more important, answer to the threat. In the US the FAA has experimented with a system. Drones can have pre-programmed software that keeps them away from prohibited areas, an approach known as “geofencing”. British engineers have come up with a system that catches drones with a net and then softly lands them with a parachute. Dutch police have even attempted to train eagles to catch drones in the sky and return them to their trainers as if they were song birds. The closure at Gatwick will give ideas such as these a mighty push forward.

1.Compared to birds, drones have become a more serious threat to airplane crash in that _____.

A.drones are much heavier than birds in general

B.drones usually fly even faster than birds

C.drones will attack airplanes on purpose

D.drones are made of rigid and dense materials

2.The sentence “The extended closure of Gatwick was a justified response to this threat.” should be put in _____.

A.① B.②

C.③ D.④

3.It can be inferred from the article that _____.

A.The decreasing size of drones recently has led to frequent accidents of this kind.

B.Among the solutions, technology is considered to be a more reliable one.

C.The FAA has adopted a “geofencing” system with the help of trained eagles.

D.The British police think environmentalists conducted the latest incident at Gatwick.

4.What can be a suitable title for the article?

A.Drones or birds, which is more harmful?

B.How to stop unmanned aerial vehicles?

C.Several drones close Gatwick airport.

D.Drones have become a pressing issue.

Many people have been talking about the way in which the world will come to an end in 2012. Everybody wants to find out if December 21, 2012 is the last day of the earth. The rumor has already been spreading for a very long time. The Mayan’s prediction can account for the rumor. According to the rumor, the earth will experience dramatic changes in 2012 and the changes will be disastrous to all of the living creatures on earth. It is widely assumed that a Planet X will return to orbit the solar system. The return of Planet X will have a destructive effect on the solar system as well as on some planets including the Neptune, the Jupiter and the earth. Planet X will cross into their orbits. There’s a possibility that Jupiter will change into a little sun at this time, so folks will be well placed to see two suns in the sky in 2012.

The solar flares (耀斑) that occur in a 11-year cycle will reach their highest point in 2012. The powerful solar flares will affect the magnetic field of the earth and cause disasters. On December 21, 2012, the sun and the earth will line up in the same line at the equator(赤道). The winter solstice(冬至) only occurs once every 25,800 years. The events in the universe are signals that the world will come to an end. As a result of the solar flares, lots of disasters will happen that will destroy the face of the whole earth. Scientists are making the guess primarily based on the Mayan Long Count Calendar.

Many films have been made about the end of the world including End Game by Alex Jones and End Clock: Nostradamus 2012. The former provides insights about the way the world will become one state. After the world government is in place, it’s going to be easy to exterminate 80% of the people in the world. The rest will continue to live with assistance from advanced technology.

No one knows whether the world will end on December 21, 2012: There is no clear answer until the day arrives. Just as the Mayans claim, it will not be the time for the world to end. Instead, it will be the dawn of a fresh start.

1. What is the passage mainly about?

A. Information about end-of-the-world predictions.

B. Different opinions about end-of-the-world predictions.

C. Some doubts about end-of-the-world predictions.

D. Destructive effects of the end of the world.

2.Which of the following things will NOT happen if the end of the world really happens?

A. Humans will see two suns at the same time.

B. The earth will look completely different.

C. The earth and the moon will line up in the same line.

D. The solar flares will become stronger than before.

3.The underlined word “exterminate” in Paragraph 3 probably means “__________”.

A. save              B. kill             C. help             D. rule

4.What is the author’s attitude to the rumor that the world will end?

A. Optimistic    .       B. Sad.             C. Unconcerned.     D. Scared.
