Monkeys seem to have a way with numbers.

A team of researchers trained three Rhesus monkeys to associate 26 clearly different symbols consisting of numbers and selective letters with 0-25 drops of water or juice as a reward. The researchers then tested how the monkeys combined—or added—the symbols to get the reward.

Here’s how Harvard Medical School scientist Margaret Livingstone, who led the team, described the experiment: In their cages the monkeys were provided with touch screens. On one part of the screen, a symbol would appear, and on the other side two symbols inside a circle were shown. For example, the number 7 would flash on one side of the screen and the other end would have 9 and 8. If the monkeys touched the left side of the screen they would be rewarded with seven drops of water or juice; if they went for the circle, they would be rewarded with the sum of the numbers—17 in this example.

After running hundreds of tests, the researchers noted that the monkeys would go for the higher values more than half the time, indicating that they were performing a calculation, not just memorizing the value of each combination.

When the team examined the results of the experiment more closely, they noticed that the monkeys tended to underestimate(低估) a sum compared with a single symbol when the two were close in value—sometimes choosing, for example, a 13 over the sum of 8 and 6. The underestimation was systematic: When adding two numbers, the monkeys always paid attention to the larger of the two, and then added only a fraction(小部分) of the smaller number to it.

“This indicates that there is a certain way quantity is represented in their brains, ”Dr. Livingstone says. “But in this experiment what they’re doing is paying more attention to the big number than the little one.”

1.What did the researchers do to the monkeys before testing them?

A.They fed them. B.They named them.

C.They trained them. D.They measured them.

2.How did the monkeys get their reward in the experiment?

A.By drawing a circle. B.By touching a screen.

C.By watching videos. D.By mixing two drinks.

3.What did Livingstone’s team find about the monkeys?

A.They could perform basic addition. B.They could understand simple words.

C.They could memorize numbers easily. D.They could hold their attention for long.

4.In which section of a newspaper may this text appear?

A.Entertainment. B.Health. C.Education. D.Science.

California has lost half its big trees since the 1930s, according to a study to be published Tuesday and climate change seems to be a major factor（因素）.

The number of trees larger than two feet across has declined by 50 percent on more than 46, 000 square miles of California forests, the new study finds. No area was spared or unaffected, from the foggy northern coast to the Sierra Nevada Mountains to the San Gabriels above Los Angeles. In the Sierra high country, the number of big trees has fallen by more than 55 percent; in parts of southern California the decline was nearly 75 percent.

Many factors contributed to the decline, said Patrick Mclntyre, an ecologist who was the lead author of the study. Woodcutters targeted big trees. Housing development pushed into the woods. Aggressive wildfire control has left California forests crowded with small trees that compete with big trees for resources（资源）.

But in comparing a study of California forests done in the 1920s and 1930s with another one between 2001 and 2010, Mclntyre and his colleagues documented a widespread death of big trees that was evident even in wildlands protected from woodcutting or development.

The loss of big trees was greatest in areas where trees had suffered the greatest water shortage. The researchers figured out water stress with a computer model that calculated how much water trees were getting in comparison with how much they needed, taking into account such things as rainfall, air temperature, dampness of soil, and the timing of snowmelt（融雪）.

Since the 1930s, Mclntyre said, the biggest factors driving up water stress in the state have been rising temperatures, which cause trees to lose more water to the air, and earlier snowmelt, which reduces the water supply available to trees during the dry season.

1.What is the second paragraph mainly about?

A.The seriousness of big-tree loss in California.

B.The increasing variety of California big trees.

C.The distribution of big trees in California forests.

D.The influence of farming on big trees in California.

2.Which of the following is well-intentioned（出于好心的） but may be bad for big trees?

A.Ecological studies of forests. B.Banning woodcutting.

C.Limiting housing development. D.Fire control measures.

3.What is a major cause of the water shortage according to Mclntyre?

A.Not enough snowmelt. B.A longer dry season.

C.A warmer climate. D.Dampness of the air.

It was a cold winter．The wind blew all night and the snow was blinding．When morning came，my three children and I got up and made our way to the windows. As we looked out of the window, we saw that the henhouse was gone．Our three hens had been blown away by the cold wind．

I looked at the emptiness outside．Then I saw all three chickens sitting around the edge of a white bucket．I couldn't believe my eyes! How was this violent wind not blowing them into the field beyond？I quickly pulled on long snow pants and heavy winter coat, wrapped a scarf around my neck and stuck my feet into large boots．

I shouted at the wind as it blew．I was alone，struggling in the snow．They stared out the window into the vast white sea of snow, peering at any sign of movement. Outside I heard the sound of my boots as I walked against the wind．

As the snow circled around me，I steadily made my way to the soft cluck-cluck-cluck sound my hens always made．When I reached them，I saw that their little feet were holding on to the edge of the bucket，heads bent forward and away from the wind. I gently lifted each hen and put it carefully into the warm inside．Then I began the freezing walk back to the small shed directly behind our house. One by one I laid my chickens on the cold floor，and they began to cluck softly．

As I shut the shed doors，my eyes went directly to the window where my children were watching. They jumped up and down cheering，and so did I! I wasn't some dragon slayer(屠龙者) from a fairy tale. I was simply a mom，but the look on my children's faces told me that they thought I was a hero mom．

1.Seeing all three chickens sitting around the bucket, the author felt_______?
