[单项选择]If you didn’t know any better, you might mistake the Newark Earthworks in southern Ohio for the product of some giant heaven spirit who went crazy with an Etch A Sketch. The Earthworks are actually a series of huge geometric mounds that anthropologists believe were created two millennia ago by ancestors of Native Americans called the Hopewell people. The most significant feature still standing is known as the Octagon (八角广场), which has 550-foot-long earthen walls and a footprint big enough to hold four Roman Colosseums (古罗马的圆形大剧院). The structure is connected, via two parallel embankments, to a perfect, 20-acre circle. Together the two shapes form a sophisticated astronomical observatory—scientists have discovered that the structure is precisely aligned with the 18.6-year lunar cycle’s northernmost moonrise. The residents of Newark will tell you that it is also precisely aligned with the ninth fairway at the private Moundbuilders Country Club.

When a customer fell deathly ill, waitress Jessica Grant called on a skill she never thought she’d need.
The man eating chicken chimichangas at table 25 asked for more tortillas and a Dr Pepper.

[单项选择] When former President Ronald Reagan fell and broke his hip at the age of 89, he joined a group of more than 350, 000 elderly Americans who fracture their hips each year. Suffering from advanced Alzheimer’’s disease, Reagan was in one of the highest-risk groups for this type of accident. The incidence of hip fractures not only increases after age 50, but doubles every five to six years as the risk of falling increases. Slipping and tumbling are not the only causes of hip fractures; weakened bones sometimes break spontaneously. But falling is the major cause, representing 90% of all hip fractures. These injuries are not to be taken lightly. According to the American Academy of Orthopedic Surgeons, only 25% of those who suffer hip fractures ever fully recover; as many as 20% will die within 12 months. Even when patients do recover, nearly half will need a cane or a walker to get around. When it comes to hip fractures, the most dangerous place for elderly Americans, it turns
A. offer advice on how to prevent hip fractures.
B. emphasize the importance of health precautions.
C. discuss the seriousness of hip fractures.
D. identify the causes of hip fractures.
