C
Somewhere in the sky, lightning is forming. Although the possibility of getting struck in your lifetime is roughly 1 in 12,000, a human does provide an attractive target for lightning bolts(闪电). Here's what you should expect if you ever find yourself in the path of lightning.
A lot can happen in the three milliseconds it takes for a lightning bolt to course through your body. Lightning strikes may leave you with deep wounds, often accompanied with third - degree burns. Your clothes might even be torn by the explosive force of the surrounding air being superheated to up to 27,700 ℃. Blood vessels(血管) exploding from the electric shock and heat often create something called a Lichtenberg figure on your skin. This is a pattern of scars(伤疤) that branches out across your body like a tree.
But it doesn't end there. You might also be faced with a lifetime of neurological(神经系统的) conditions for reasons that scientists still don't fully understand. It's also possible that you will suffer pain.
In some cases, however, a lightning strike can lead to strange super talents. In a blog post, University of Miami neuroscientist Berit Brogaard writes about an incident where a surgeon who was struck by lightning developed an urge to learn to play the piano. He began to compose music he had started hearing in his head since the strike. This type of phenomenon confuses scientists.
One theory that Brogaard says is that cell death caused by being struck by lightning could cause a one - time flooding of the brain with neurotransmitters(神经递质) that are released from the dying neurons(神经元). This causes a rewiring of neurons, providing access to areas of the brain that were previously inaccessible.
Cool as it would be, you shouldn't count on lightning turning you into a genius in one flash. Most of its results are painful, and could stay with you for the rest of your life.
28. What can we learn from the first two paragraphs?
A. 1 in 12,000 may die from lightning bolts.
B. Lightning attacks can heat bodies to 27,700℃.
C. Branching scars are typical after lightning attacks.
D. Humans are the most likely target for lightning bolts.
29. What happened to the surgeon after the strike?
A. His unexplored brain areas were activated.
B. His brain was left in a fixed state of death.
C. He suffered a lifetime of neurological pain.
D. He recalled hidden memories about music.
30. What does the underlined word “This” refer to in paragraph 5?
A. The cell death due to lightning strikes.
B. The flooding of brain's neurotransmitters.
C. The rewiring of brain neurons.
D. The release of dying neurons.
31. What is the text mainly about?
A. The process of lightning formation.
B. The chances of surviving a lightning strike.
C. The possibility of lightning making a genius.
D. The consequences of being struck by lightning.
