Thousands of dead red-winged blackbirds fell from the sky in an Arkansas town on New Year’s Eve after massive injuries, tests by Arkansas officials concluded on Monday. Some 5,000 birds mysteriously fell from the sky in Beebe, Arkansas after dark on New Year’s Eve. “The birds suffered from acute physical injuries leading to internal hemorrhage（大量出血） and death. There was no sign of infectious disease,” the Arkansas Game and Fish Commission said in a statement. The birds were otherwise healthy, it said.

One theory is that birds were frightened by New Year's fireworks and flew into buildings or other objects. “Loud noises were reported shortly before the birds began to fall from the sky,” the statement said, adding that blackbirds have poor night vision and seldom fly at night.

　　Another theory was that severe weather such as lightning accounted for the loud noises but this was discounted because the violent weather had already left the area. “We’re leaning more toward a stress event," said Arkansas Game and Fish Commission spokesman Keith Stephens.

The commission also is trying to determine what caused the deaths of up to 100,000 fish over a 20-mile stretch of the Arkansas River near a dam in Ozark, 125 miles west of Beebe. The fish were discovered on December 30. Stephens said the commission expected results on the fish tests in probably a month. Since almost all the fish were one species -- bottom-feeding drum, Stephens said, the test was very important. Stephens also said: “The events do not appear related.” Both that section of the river and the air at the site of the bird deaths were tested for toxins(毒素). Beebe is a town of about 4,500 people located 30 miles northeast of the state capital.

What is NOT the probable reason why the dead red-winged blackbirds fell from the sky?

A. Internal hemorrhage B. Fireworks

C. Lightning weather D. Murder

In the third paragraph, the underlined word discounted probably mean________.

A. not to reduce cost B. not to believe

Researchers found that people become happier and experience less worry after they reach the age of fifty. In fact, they say by the age of eighty-five, people are happier with their life than they were when they were eighteen years old.

The findings came from a survey of more than 340,000 adults in the United States. The Gallup(民意调查) Organization questioned them by telephone in 2010. At that time, the people were between the ages of eighteen and eighty-five.

The researchers asked questions about emotions like happiness, sadness and worry. They also asked about mental or emotional stress.

Arthur Stone at Stony Brook University in New York led the study. His team found that levels of stress were highest among adults between the ages of twenty-two and twenty-five. The findings showed that stress levels dropped sharply after people reached their fifties. Happiness was highest among the youngest adults and those in their early seventies. The people least likely to report feeling negative emotions were those in their seventies and eighties.

Researchers say they do not know why happiness increases as people get older. One theory is that, as people grow older, they grow more thankful for what they have and have better control of their emotions. They also spend less time thinking about bad experiences.

Professor Stone says the emotional patterns could be linked to changes in how people see the world, or maybe even changes in brain chemistry.

The researchers also considered possible influences like having young children, being unemployed or being single. But they found that influences like these did not affect the levels of happiness and well-being related to age.

The study also showed that men and women have similar emotional patterns as they grow older. However, women at all ages reported more sadness, stress and worry than men.

What can be the best title of the text?

A．Happiness Varies with Ages	B．Experience More, Worry Less
C．The Older, the Wiser	D．Being Young, Being Happy

We can learn from the research that _________.

A．they miss the old days	B．they are physically weak

What would the author probably talk about next?
