Global warming is already cutting substantially into potential crop yields in some countries—to such an extent that it may be a factor in the food price【C1】______that have caused worldwide stress in recent years, researchers suggest in a new study. Wheat yields in recent years were down by more than 10 percent in Russia and by a few percentage points【C2】______in India, France and China compared with【C3】______they probably would have been without rising【C4】______, according to the study. Corn yields were【C5】______a few percentage points in China, Brazil and France from what would have been【C6】______said the researchers, whose findings were published in Friday"s【C7】______of the journal Science. Some countries saw small gains from the temperature increases, however. And in all countries, the【C8】______carbon dioxide that humans are【C9】______into the air acted as a【C10】______that encouraged plant growth,【C11】______some of the losses from rising temperatures caused by that same greenhouse gas. 【C12】______, the study"s authors found that when the gains in some countries were weighed【C13】______the losses in other countries, the overall global【C14】______of climate change has been small so far losses of a few percentage points for wheat and corn from what they would have been【C15】______climate change.

TV is so often a parent"s good Mend, keeping kids happily occupied so the grownups can cook dinner, answer the phone, or take a shower. But【C1】______that electronic babysitter is not an educational【C2】______According to a recent research, babies who watch TV are more likely to have【C3】______cognitive development and language at 14 months,【C4】______if they"re watching programs【C5】______for adults and older children. It"s surprising that TV-watching made a【C6】______at such a tender age. This new study【C7】______259 lower-income families in New York, most of whom spoke Spanish as their【C8】______language at home. Other studies examining higher-income families have come to the【C9】______conclusion: TV watching not only isn"t educational, but it seems to【C10】______babies" development. Babies who watched 60 minutes of TV daily had developmental【C11】______one-third lower at 14 months than babies who weren"t watching that much TV. The【C12】______may be due to the fact that when kids and parents are watching TV, they"re【C13】______talking, playing, and interactions that are【C14】______to learning and development. But what about "【C15】______" TV, like Sesame Street The researchers didn"t find any pluses or minuses when【C16】______to non-educational programs designed for small children, like Sponge-Bob SquarePants.【C17】______research by some of the same scientists has found that parents whose children watch non-educational TV programs like SpongeBob SquarePants spend【C18】______time reading to their children or teaching them. The latest study of educational TV programs like Sesame Street adds more【C19】______to a recommendation from the American Academy of Pediatrics that babies under age【C20】______watch no TV at all. 【C16】
