A Charlotte, N.C., man was charged with first-degree murder of a 79-year-old woman whom police said he scared to death. In an attempt to evade policemen after a bank robbery, the Associated Press reports that 20-year-old Larry Whitfield broke into the home of Mary Parnell. Police say he didn’t touch Parnell but that she died after suffering a heart attack that was caused by terror. Can the guy be held responsible for the woman’s death? Prosecutors(公诉人) said that he can under the state’s murder rule, which allows someone to be charged with murder if he or she causes another person’s death while committing or fleeing from a severe crime like robbery—even if he or she doesn’t kill someone on purpose.
But, medically speaking, can someone actually be frightened to death? We asked Martin Samuels, chairman of the neurology department at Brigham and Women’s Hospital in Boston.
Absolutely, no question about it.
The body has a natural protective method called the fight-or-flight response(战或逃反应), which was originally described by Walter Cannon,the chairman of Harvard University’s physiology department from 1906 to 1942. If, in the wild, an animal is faced with a life-threatening situation, the autonomic nervous system responds by increasing heart rate, increasing blood flow to the muscles, and slowing digestion, among other things. All of this increases the chances of succeeding in a fight or running away from an aggressive beast. This process certainly would be of help to primitive humans. However, in the modern world there is obvious decline of the fight-or-flight response.
The autonomic nervous system uses the chemical messenger to send signals to various parts of the body to activate the fight-or-flight response. This chemical is toxic in large amounts; it damages the organs such as the heart, lungs, liver and kidneys. It is believed that almost all sudden deaths are caused by damage to the heart. There is almost no other organ that would fail so fast as to cause sudden death. Kidney failure, liver failure, those things don’t kill you suddenly.
By the way, any strong positive or negative emotions such as happiness or sadness can cause the same result. There are people who have died in intercourse or in religious passion. There was a case of a golfer who hit a hole in one, turned to his partner and said, “I can die now”, and then he dropped dead. For about seven days after the 9/11 terrorist attacks on the World Trade Center and Pentagon there was an increase of sudden cardiac death among New Yorkers.Why the Charlotte, N.C., man was charged?
A. Because he threatened the policemen to kill an old woman.
B. Because he caused an old woman’s terror and she died.
C. Because he beat an old woman and caused her heart attack
D. Because he murdered an old woman while robbing a bank.What is Martin Samuels’ attitude to the possibility of being frightened to death?

Are we getting more stupid? According to Gerald Crabtree, a scientist at Stanford University in the US, we are.
You may not want to hear this, but Crabtree believes that human intelligence reached its peak more than 2,000 years ago and ever since then has been going downhill. “If an average Greek from 1,000 BC were transported to modern times, he or she would be one of the brightest among us,” Crabtree told The Guardian.
At the heart of Crabtree’s thinking is a simple idea. In the past, intelligence was critical for survival when our ancestors had to avoid dangerous animals and hunt for food. The difference of being smart or stupid is often life or death. However, after the spread of agriculture, when our ancestors began to live in dense farming communities, the need to keep their intelligence in peak condition gradually reduced.
This is not hard to understand. Most of the time, pressure is what keeps us going – you need the pressure from your teachers to finish your homework; the pressure of looking pretty prompts you to lose weight when summer comes. And the same is also true of our intelligence – if we think less, we become less smart.
These mutations(变异) are harmful to our intelligence and they were all developed in the past 3,000 years. The other evidence that Crabtree holds is in our genes. He found that among the 2,000 to 5,000 genes that we have that determine human intelligence, there are two or more mutations in each of us.
However, Crabtree’s theory has been criticized by some who say that early humans may have better hunting and surviving abilities, but people today have developed a more diverse intelligence. For example, spearing a tiger doesn’t necessarily require more brainpower than playing chess or writing a poem. Moreover, the power of modern education means a lot more people have the opportunity to learn nowadays.
“You wouldn’t get Stephen Hawking 2,000 years ago. He just wouldn’t exist,” Thomas Hills of the University of Warwick, UK, told Live Science. “But now we have people of his intellectual capacity doing things and making insights that we would never have achieved in our environment of evolutionary adaptation.”What is Crabtree’s recent finding according to the article?
A.The Greeks from 1,000 BC could have been the smartest in human history. |
B.Our ancient ancestors had no better surviving abilities than we do nowadays. |
C.Humans have been getting steadily more intelligent since the invention of farming. |
D.Mutations in genes that decide human intelligence have affected the development of intelligence. |
According to Crabtree, ancient humans _______.
A.had much more genes that determine human intelligence |
B.were forced to be smart due to natural selection pressures |
C.relied more on group intelligence than individual intelligence |
D.developed a diverse intelligence to adapt to the harsh realities |
Some argue that Crabtree’s theory is false because they think _______.
A.people today are under much more pressure than early humans |
B.it’s ridiculous to compare a hunter’s and a poet’s intelligence |
C.modern education is far more advanced than ancient education |
D.human intelligence nowadays is different from that of the distant past |
What is Thomas Hills’ attitude toward Crabtree’s theory?
A.Supportive | B.Unfavorable |
C.Worried | D.Confused. |
Hi, everybody. Over the past couple months, most of the political headlines you’ve read have probably been about the government shutdown and the launch of the Affordable Care Act. And I know that many of you have rightly never been more frustrated with Washington.
But if you look beyond those headlines, there are some good things happening in our economy. And that’s been my top priority since the day I walked into the Oval Office.
After decades in which the middle class was working harder and harder just to keep up, and a punishing recession that made it worse, we made the tough choices required not just to recover from crisis, but to rebuild on a new foundation for stronger, more durable economic growth.
Five years later, we have fought our way back. Our businesses have created 7.8 million new jobs in the past 44 months. Another 200,000 Americans went back to work last month.
The American auto industry has come roaring back with more than 350,000 new jobs – jobs churning out and selling the high-tech, fuel-efficient cars the world wants to buy. And they’re leading the charge in a manufacturing sector that has added jobs for the first time since the 1990s – a big reason why our businesses sell more goods and services “Made in America” than ever before.
We decided to reverse our addiction to foreign oil. And today, we generate more renewable energy than ever, more natural gas than anybody, and for the first time in nearly 20 years, America now produces more oil than we buy from other countries.
We decided to fix a broken health care system. And even though the rollout of the marketplace where you can buy affordable plans has been rough, so far, about 500,000 Americans are poised to gain health coverage starting January 1st. And by the way, health care costs are growing at the slowest rate in 50 years.
And one more thing: since I took office, we’ve cut our deficits by more than half. And that makes it easier to invest in the things that create jobs – education, research, and infrastructure.
Imagine how much farther along we could be if both parties were working together. Think about what we could do if a reckless few didn’t hold the economy hostage every few months, or waste time on dozens of votes to repeal the Affordable Care Act rather than try to help us fix it.
In the weeks ahead, I’ll keep talking about my plan to build a better bargain for the middle class. Good jobs. A good education. A chance to buy a home, save, and retire. And yes, the financial security of affordable health care. And I’ll look for any willing partners who want to help.
Because of your hard work and tough sacrifices over the past five years, we’re pointed in the right direction. But we’ve got more work to do to keep moving that way. And as long as I’m President, I’ll keep doing everything I can to create jobs, grow the economy, and make sure that everyone who works hard has a chance to get ahead. Thanks, and have a great weekend.Which of the following is not the reason for people’s frustration with the government?
A.The government shut down |
B.Unemployment rate |
C.The addiction to foreign oil |
D.The launch of the Affordable Care Act |
Why does the president mention more goods and services “Made in America”?
A.To show that American goods and services are very popular. |
B.To indicate that American people should be dependent on themselves. |
C.To show that the employment rate has been increased. |
D.To show that American auto industry enjoys high technology. |
What’s the meaning of the underlined word “repeal”?
A.To abolish | B.To protect |
C.To strengthen | D.To weaken |
According to the speech, which of the following can be implied?
A.American people have every reason to feel frustrated with the government. |
B.Health care costs are growing at the slowest rate in 50 years. |
C.The president feels sorry that the economy is not moving in the right direction. |
D.Some government officials don’t agree with the president on the medical care system. |
Everyone gathered around and Paddy read out loud, slowly, his tone growing sadder and sadder. The little headline said: BOXER RECEIVES LIFF SENTENCE.
Frank Cleary, aged 26, professional boxer, was today found guilty of the murder of Albert Gumming, aged 32, laborer, last July. The jury(陪审团) reached its decision after only ten minutes, recommending the most severe punishment to the court. It was, said the Judge, a simple case. Cumming and Cleary had quarreled violently at the Harbour Hotel on July 23rd and police saw Cleary kicking at the head of the unconscious Gumming. When arrested, Cleary was drunk but clear-thinking.
Cleary was sentenced to life imprisonment with hard labour. Asked if he had anything to say, Cleary answered, “Just don’t tell my mother.”
“It happened over three years ago,” Paddy said helplessly. No one answered him or moved, for no one knew what to do. “Just don’t tell my mother,” said Fee numbly(麻木地). “And no one did! Oh, God! My poor, poor Frank!”
Paddy wiped the tears from his face and said. “Fee, pack your things. We’ll go to see him.”
She half-rose before sinking back, her eyes in her small white face stared as if dead. “I can't go,” she said without a hint of pain, yet making everyone feel that the pain was there. “It would kill him to see me. I know him so well—his pride, his ambition. Let him bear the shame alone, it’s what he wants. We’ve got to help him keep his secret. What good will it do him to see us?”
Paddy was still weeping, not for Frank, but for the life which had gone from Fee’s face, for the dying in her eyes. Frank had always brought bitterness and misfortune, always stood between Fee and himself. He was the cause of her withdrawal from his heart and the hearts of his children. Every time it looked as if there might be happiness for Fee, Frank took it away. But Paddy’s love for her was as deep and impossible to wipe out as hers was for Frank.
So he said, “Well, Fee, we won’t go. But we must make sure he is taken care of. How about if I write to Father Jones and ask him to look out for Frank?”
There was no excitement in the eyes, but a faint pink stole into her cheeks. “Yes, Paddy, do that. Only make sure he knows not to tell Frank we found out. Perhaps it would ease Frank to think for certain that we don’t know.”Paddy cried because he thought ___________.
A.Frank did kill someone and deserved the punishment |
B.Frank should have told Fee what had happened |
C.what had happened to Frank was killing Fee |
D.Frank had always been a man of bad moral character |
The underlined sentence “She half-rose before sinking back…” in Paragraph 6 shows that___________.
A.Fee was so heart-broken that she could hardly stand up |
B.Fee didn’t want to upset Paddy by visiting Frank |
C.Fee couldn’t leave her family to go to see Frank |
D.Fee struggled between wanting to see Frank and respecting his wish |
What can be inferred from the passage?
A.The jury and the judge agreed on the Boxer’s Sentence of Life Imprisonment. |
B.The police found Gumming unconscious, heavily struck by Frank. |
C.The family didn’t find out what had happened to Frank until 3 years later. |
D.Frank didn’t want his family to know the sentence to him, most probably out of his pride. |
What is Frank and Paddy’s probable relationship with Fee?
A.Frank is Fee’s son and Paddy is Fee’s brother. |
B.Frank is Fee’s son and Paddy is Fee’s husband. |
C.Frank is Fee’s brother and Paddy is Fee’s lover. |
D.Frank is Fee’s lover and Paddy is Fee’s husband. |
Humans may not have landed on Mars (火星) just yet, but that isn’t stopping a European company from devising a plan to send four people to the Red Planet within the next few years. This project, called Mars One, aims to send a small group of people to Mars in 2022 and eventually establish a permanent colony on the planet.
“Everything we need to go to Mars exists,” said Mars One co-founder Bas Lansdorp in March 2014. “We have the rockets to send people to Mars, the equipment to land on Mars, the robots to prepare the settlement for humans. For a one-way mission, all the technology exists.” Yet the four astronauts chosen for the trip will be stuck on Mars—forever. And despite Mars One’s thorough planning, there are a number of challenges that may prevent the mission from ever taking place. The biggest road block could be the mission's huge cost ($6 billion). However, Lansdorp is confident that Mars One will be able to fund the project by selling the broadcast rights for the mission and subsequent experiences living on the planet.
Those broadcast rights will also play a part in helping to select the people who will be sent to Mars. Lansdorp said the company will hold a selection process similar to a reality show. Lansdorp is expecting at least 1 million applications from people around the world. In addition to the cost, several other potential problems could inhibit (阻止) the mission to Mars.
“It’s even more challenging to send people there with life support, with food, with air, with all the other things like books, entertainment, means of communication and of providing for their own resources for a long stay on Mars,” said Adam Baker, senior lecturer in space engineering at Kingston University in London. “The size of the rockets you’d need to do this would be absolutely colossal.”According to Project Mars One, humans could send four people to Mars within the next ________years.
A.seven | B.eight | C.ten | D.six |
According to Bas Lansdorp, which of the following is NOT TRUE?
A.Robots are prepared for the settlement for humans. |
B.He could not come up with the fund for Mars One. |
C.We humans have the rockets to send people to Mars. |
D.The equipment is ready for humans to land on Mars. |
The word “colossal” in the last paragraph is closest in meaning to ___________.
A.very large | B.very small |
C.medium | D.average |
Which of the following is an appropriate title for this passage?
A.Ready for a Round Trip to Mars |
B.Ready for a Short Visit to Mars |
C.Ready for a One-way Trip to Mars |
D.Ready for a Walk on Mars |
