Agitated Sunspot Cause

If the lights in your house keep flickering, blame frequent sunspots.
A sunspot is actually charged particles flying at the speed of 3 million kilometers an hour out of the surface of the sun to form sun storms.
Every 11 years, the sun, as its energy accumulates inside up to a certain point, will send out streams of charged particles. (46) .
One is that the magnetic field of the earth is much disturbed because of the sun’s interference in the ionosphere, which is 80 to 500 kilometers above the earth. Wireless short-wave communication, which depends on the wave’s reflection against this layer of atmosphere, is likely to be jammed. (47) .
Scientists also say that the active movement of the charged sun storm also has earthquakes. According to a research conducted by the Russian scientists from 1957 to 1960, the frequency of earthquakes can be linked to the movement of t

[填空题]Agitated Sunspot Cause Trouble
If the lights in your house keen flickering, blame frequent sunspots. A sunspot is actually charged particles flying at the speed 6f 3 million kilometers an hour out of the surface of the sun to form sun storms. (1) .
The earth, which is directly energized by the sun, is influenced by sun storms in a number of ways. (2) Wireless short-wave communication, which depends on the wave’s reflection against this layer of atmosphere, is likely to be jammed. It is said that mobile phone communication may be affected too. (3) According to a research conducted by the Russian scientists from 1957 to 1960, the frequency of earthquakes can be linked to the movement of the sunspots.
Though little research has been carried out about how exactly the sunspot will negatively harm the health of the people, a paper published by a North Korea observatory says that sun storms may cause an increase in the incidence of hear

[单项选择]Scraps of food could soon be helping power your home, thanks to an ultra-cheap bacteria-driven battery. Its developers hope that instead of feeding the dog or making garden compost(混合肥料) ,organic household waste could top up your home’s electricity.
Although such "microbial fuel cells" (MFCs)have been developed in the past, they have always proved extremely inefficient and expensive. Now Chris Melhuish and technologists at the University of the West of England(UWE)in Bristol have come up with a simplified MFC that costs as little as ￡10 to make.
Right now, their fuel cell runs only on sugar cubes, since these produce almost no waste when broken down, but they aim to move on to carrot power. "It has to be able to use raw materials, rather than giving it a refined fuel," says Melhuish.
Inside the Walkman-sized battery, a colony of E. coil bacteria produce enzymes that break down carbohydrates, releasing hydrogen atoms. The cell also contains chemicals that drive a series o
