【题目】阅读短文，完成下列问题。
A
In the film The Revenant the Leonardo DiCaprio adventure takes the basic facts of real-life frontiersman Hugh Glass's sufferings and adds extra characters, extra ultra violence and more horse guts.
Hugh Glass was a frontiersman working in the upper Missouri river area in the early years of the 19th century. On a fur trapping expedition in 1823, he was attacked and injured by a grizzly bear.
_____________
Hugh Glass (Leonardo DiCaprio) is one of a group of men finishing up a fur trapping expedition in the wilderness. They are attacked by Ree (Arikara) warriors. Whoosh! Someone gets impaled on a spear. Bang! Someone gets shot off his horse. Crack! Someone's bones shatter. There's a fearless close-up of an arrow thwacking into a face, a gun butt bashing into a face, a flying kick to a face. A horse gets shot in the face. It's exceptionally well choreographed (取景) and filmed.
This scene is based on a real-life incident: In June 1823, Ashley's band of around 70 men was attacked by Arikara warriors –they estimated around 600, though in the film it's more like a dozen.
Characters
In the film, 10 men get away. Fitzgerald is a fighter and racist, so he's the bad guy. Glass is the good guy, because he loves his son (who is half-Pawnee) in a gruff, manly way that involves telling him off a lot. The back story about Glass's love for a Pawnee woman is fiction. It has been suggested the real Glass had such a relationship, but there's no firm evidence –and no evidence that he had any children.
Wildlife
As the men make their way through a forest, Glass happens upon two bear cubs and their angry mama. If you felt pale after the face-smashing scene at the start, reach for the smelling salts. Chomp! Growl! Shake! The bear sniffs him to see if he's dead, then jumps up and down on his back. Splinter! Howl! Slash! Glass shoots the bear. Anyway, while historians are not certain of the precise details, the real Glass did get into a fight with a real bear, sometime in August 1823.
Murder
The men find Glass in a rum old state. Captain Henry pays Fitzgerald, Bridger and Hawk to stay behind until it is time for Glass's inevitable burial. When the captain leaves, Fitzgerald tries to bump Glass off. Hawk interrupts, so Fitzgerald bumps him off instead. This didn't happen in real life, because Hawk didn't exist. In the film, the weak Glass sees Fitzgerald kill his son, giving him an extra motivation to stay alive and seek revenge.
Survival
The real Glass survived his abandonment and dragged his battered body over hundreds of miles of terrain in pursuit of the men who left him for dead. Though he could read and write, Glass never set his story down in his own hand. It was first published by another writer in a Philadelphia journal in 1825. It may well have been modified then. It has been modified many times since.
Hardship
The film has invented some extra obstacles for Glass: it is snowing throughout, even though in real life his trek took place between August and October; the Arikara track him and chase him into a tree; he has to hollow out a dead horse to make himself a sleeping bag. As for the ending, it has been changed in one significant way: in real life, nobody got killed.

（1）We can know for sure after reading the passage that real Hugh Glass _____.
A.finally survived for he was determined to take revenge on Fitzgerald killing Hawk
B.fell in love with a Pawnee woman and soon after they had a clever and brave boy
C.wrote nothing about his suffering despite the fact that he was actually educated
D.nearly got killed by Fitzgerald and Hawk under the instruction of Captain Henry
（2）To play the role of Hugh Glass, Leonardo DiCaprio must have ______.
A.fought against three bears courageously
B.walked in snow with great difficulty
C.rode a horse time and time again
D.grasped skills for surviving in the wild
（3）Which of the following can be the best subtitle for the 4th and 5th paragraphs?
A.Violence
B.Setting
C.Horror
D.Special effects
（4）We can see here and there in the passage that the writer thinks of the movie as a _____ adaptation.
A.faithful
B.disappointing
C.successful
D.heartless
（5）The passage is intended to inform readers _____.
A.how tragic Hugh Glass's experience is
B.how well Leonardo DiCaprio performs in The Revenant
C.how bloody the movie The Revenant is
D.how historically accurate The Revenant is
