l 流星的光只能维持1秒钟,但是TLP 维持了20分钟

l 岩石虽然能发光,但是他们的光很弱,研究人员在晚上观察,本身不发光的月球会反射,太阳光比岩石的光要更明亮,所以人们观察不到

TLP 月球暂现现象

 

背景知识补充:

TLPTransient lunar phenomena),月球暂现现象。阿里斯塔克斯环形山之谜,是所谓的月球暂现现象,从地球上看它是月球上最大的亮点,而且会改变颜色,有时产生红色或蓝色的光芒,并排放出气体。

阿里斯塔克斯陨石坑附近的地区时常有出现月球暂现现象。这类现象包含月表出现短暂的阴影和彩色色斑。对已知的资料进行的整理表明,这类现象的可信记载中有多于三分之一出现在阿里斯塔克斯陨石坑地区。1971年,阿波罗15号从110千米上空掠过阿里斯塔克斯陨石坑地区时,侦测到一股显著的ɑ粒子流。一般认为这些粒子流是由氡-222的衰变引起的。氡-222是一种放射性的气体,它的半衰期是3.8日。后来的月球探勘者确认了该地区附近的氡-222散逸现象。而月球暂现现象可以被解释为氡气的缓慢而肉眼无法觉察的泻出,或者是间断性的爆炸现象。

Essay question

Do you think that the best way to reduce air pollution is for the government to raise the cost of fuel? Use specific examples to support your answer.

Sample answer

Nowadays, there is growing concern about the environmental issues. Among them, air pollution resulting from a huge number of automobiles and coal-burning is almost the severest. The severe air pollution alarms humans of the heavy load we have exerted on the earth.  How to reduce air pollution has been a heated topic in our society. Various methods can be adopted to tackle with the pollution, but from my perspective, the best way is for the government to raise the cost of fuel.

First of all, it would improve the environment by reducing fuel consumption. Many people commuting by car do not actually need to. They just prefer to drive to work because it saves them from having to squeeze up against other people on the bus or subway. But if driving during peak traffic hours became more expensive, it would encourage more commuters to use public transportation systems, thereby largely reducing per capita gasoline usage. As a result, air pollution would be reduced a great deal, and everybody could enjoy cleaner air.

Secondly, it could serve as a large source of funding for the government for developing infrastructure. While many would likely switch over to public transportation under such a scheme, inevitably there will also be many who choose to pay for the privilege of driving to work. With this steady stream of income, the government can spend more money on developing roads and additional public transportation infrastructure in order to lessen congestion and pollution even further. As time goes on, more efficient public transportation systems can be put in place, and eventually, driving privileges during rush hour will not have to be taxed because most people will want to use subways or buses anyway.

Thirdly, higher cost of fuel makes drivers more aware of the environmental costs that driving incurs. There will be less market demand for gas guzzlers like SUVs and pickup trucks. Public transit and the notion of going green will be more popular among the middle-class adults and the kids, some of whom will hold the key to the future environmental problems. The measure will extend greater influence in the long run.

Admittedly, other ways to reduce air pollution are also applicable. For instance, scientists can employ the most cutting-edge technology to adopt new forms of energy as substitutes for fossil fuels. However, environmental protection should be everyone’s business rather than a small group of people.

Thus, I consider cost rise as the best, as well as the most effective way to reduce pollution. With some time and effort, such a scheme could lead to a cleaner and more livable environment.
