Some parents will buy any high-tech toy if they think it will help their child, but rearchers said puzzles help children with math-related skills.
Psychologist Susan Levine, an expert on mathematics development in young children the University of Chicago, found children who play with puzzles between ages 2 and 4 later develop better spatial skills. Puzzle play was found to be a significant predictor of cognition(认知) after controlling for differences in parents' income, education and the amount of parent talk, Levine said.几何体素描
The rearchers analyzed video recordings of 53 child-parent pairs during everyday activities at home and found children who play with puzzles between 26 and 46 months of age have better spatial skills when assd at 54 months of age.

"The children who played with puzzles performed better than tho who did not, on tasks that assd their ability to rotate(旋转)and translate shapes," Levine said in a statement.怎么看显卡温度
The parents were asked to interact with their children as they normally would, and about half of children in the study played with puzzles at one time. Higher-income parents tended to have children play with puzzles more frequently, and both boys and girls who played with puzzles had better spatial skills. However, boys tended to play with more complex puzzles than girls, and the parents of boys provided more spatial language and were more active during puzzle play than parents of girls.
The findings were published in the journal Developmental Science.

California has lost half its big trees since the 1930s, according to a study to be published Tuesday and climate change ems 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 rearchers 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 cau trees to lo more water to the air, and earlier snowmelt, which reduces the water supply available to trees during the dry ason.
（1）What is the cond paragraph mainly about?
A.The riousness 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.
