摘要：	"For the first time in 20 years, our infrastructure is out of the D range." So proclaimed the American Society of Civil Engineers (ASCE), which released its 2021 Report Card for American Infrastructure. This year, the overall grade for the nation's infrastructure was a C-, up from a D+ four years ago. All the categories either stayed the same or advanced slightly. The new category of stormwater infrastructure, added this year, received a D. While waterways improved slightly to a D+, ports received a B-, one of the best grades of any category. The ASCE releases such report cards every four years. They drive discussion of the nations infrastructure needs both in Congress and in the media. "Over the past four years, the U.S. made incremental gains in some categories ... [D]ue to increased investment, grades improved in aviation, drinking water, energy, inland waterways and ports. One infrastructure category-bridges-saw a decrease in grade in part because of the number of bridges that slipped to 'fair condition from 'good.'"
