[单项选择]Over the past few years, a growing number of America’s parentless children have found homes. In 2008 there were 463,000 children in foster care, a system where the government places orphans and children with parents who are abusive or unable to take care of them in the care of guardians. That is 11% down since 2002, and great news. But experts worry the trend might now go into reverse.
Some welfare advocates fear that the bad economy may cause parents with frayed nerves to abuse and neglect their children, and even cause some to abandon them. Already, several hospitals across the country have reported an increase in the frequency and severity of injuries from child abuse.
The most recent national data on child welfare available dates from September 2008, before the recession was in lull throttle; data from 2009 won’t be reported until later this year.

[单项选择]Reading 2 "Weather and Chaotic Systems"
Scientists today have a very good understanding of the physical laws and mathematical equations that govern the behavior and motion of atoms in the air, oceans, and land. Why, then, do we have so much trouble predicting the weather For a long time, most scientists assumed that the difficulty of weather prediction would go away once we had enough weather stations to collect data from around the world and sufficiently powerful computers to deal with all the data. However, we now know that weather is fundamentally unpredictable on time scales longer than a few weeks. To understand why, we must look at the nature of scientific prediction.
