| 第1题：Darkness approached and a cold, angry wind gnawed at the tent like a mad dog.Camped above treeline in the Wind River Mountains of Wyoming, the torrents of air were not unexpected and only a minor disturbance compared to the bestial gnawing going on behind my belly button. In an attempt to limit exposure of my bare bottom to the ice-toothed storm, I had pre-dug a haft dozen catholes within dashing distance. Over and over, through the long night, the same scenario was repeated: out of the bay, out of the tent, rush, squat, rush back. "Everyone can master a grief," wrote Shakespeare, "but he that has it."

"Frequent passage of unformed watery bowel movements," as described by Taver’sCyclopedic MedicalDictionary, diarrhea falls into two broad types: invasive and non-invasive.

Serious debilitation, even death, can occur from the resulting dehydration and from the spread of the bacteria to other parts of the body. Non-invasive diarrheas grow from colonies of microscopic evil-doers that set up housekeeping on, but do not invade, intestinal walls. Toxins released by the colonies cause cramps, nausea, vomiting, and massive gushes of fluid from the patient’s lower intestinal tract. Non-invasive diarrhea carries a high risk for dehydration. Who first gave the disease the name "diarrhea" A、AncientEgyptians B、An old Greek C、American soldiers D、The passage doesn’t tell |
