Can you be hit by a bullet and keep on fighting, or escape from a bomb explosion? Let's take a look at some actions in big-budget movies in summer vacation.
Survive nearby explosions
The scene: A bomb explodes nearby but the hero escapes unharmed.
The science: Powerful explosion produces quickly expanding gas travelling faster than the speed of sound. Although this big wave lasts just a few milliseconds, it can cause hidden injuries whose effects may not become obvious for several days.
No one, except the most extreme terrorists, plans to be near a bomb, so mostly, survival comes down to good fortune — the size and type of the bomb and your distance from it.
Is it possible? Stand too close and no one is going to walk away from an explosion
unharmed. Not even Iron Man.
Fight on after being shot
The scene: The bad man is shot several times, but just keeps on going.
The science: Travelling at a speed of well over 250 meters per second, bullets are full of energy, much of which is transferred to the unlucky goal. High-speed, high-calibre（口径）bullets are likely to floor a man. Smaller, slower bullets can pass straight through a body, and because skin and tissue are elastic（弹性的），the hole may close up.
Whether or not you fall or escape also depends on where you are hit. A shot to the spine（脊柱）or head will stop you in your track. But if the bullet misses vital organs, you may be able to keep going, for a while at least.
Is it possible? If your vital organs don't take a hit, you may be able to keep going, but not for long. If the bullet does floor you, blood loss finally will.
Fall from a building
The scene: A hero falls from a high building and survives.
The science: It is not the fall that kills you, but the sudden stop at the end. In the movies, falls are commonly slowed by trees, power lines, roofs and the like. Dividing one big fall into many smaller ones slows your fall, reducing the force of impact and increasing the chance of survival.
For the same reason, what you land on is also important.
How you hit the ground also influences whether or not you survive.
Is it possible? Possible but unlikely. Survival is somewhat relative. You can have a good chance to survive, but that doesn't mean you can jump up and run around. Brain injury, broken bones and chest wound are common.

B.The hole caused by a bullet in one's body can be treated as nothing has happened at all.

Anyone with a passing interest in their health will be able to rattle__off a few of the major vitamins, and possibly take an educated guess at what they do. Vitamin C, found in oranges and other fruit and vegetables, is important for wound repair. And the much－talked－about ‘sunshine’ Vitamin D, produced by the skin in response to UV light, is essential for strong bones.
But Vitamin P? It might well have you scratching your head. And that's not surprising: the term was first coined in the 1930s to describe a small group of compounds that provide pigment(天然色素) to plants, and were believed to have health benefits. Fast－forward almost a century and these compounds are now better known as flavonoids.
Today, scientists have identified between 4，000 and 6，000 different kinds and we now know they are responsible for many of the flavors and smells of fruit and vegetables and also that they protect them from invaders such as pests and bacteria.
They are equally important nutrients for the body, helping maintain bones and teeth, and for the production of the protein collagen(胶原), which provides structure to blood vessels, muscles and skin.
They are also said to help the body deal with some of the key drivers of illness, including oxidation(氧化), a natural process by which the body's cells age and can become damaged and defective(有缺陷的). That means they could help to protect against chronic diseases including cancer and heart disease.
1.Which of the following best explains “rattle off” underlined in Paragraph 1?
A.Quickly say. B.Quickly pass.
C.Quickly find. D.Quickly take.
2.What do we know about Vitamin P?
A.We would scratch our head if we took it.
B.It was made into a coin in the 1930s.
C.People didn't think it beneficial in the past.

C.Two. D.One.
4.How does Vitamin P help slow the aging process?
A.By dealing with oxidation.
B.By maintaining bones.
