单选题 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."
Diarrhea, the modem word, resembles the old Greek expression for "a flowing through." Ancient Egyptian doctors left descriptions of the suffering of Pharaohs scratched on papyrus even before Hippocrates, the old Greek, gave it a name few people can spell correctly. An equal opportunity affliction, diarrhea has laid low kings and common men, women, and children for at least as long as historians have recorded such fascinating trivia. It wiped out, almost, more soldiers in America's Civil War than guns and swords. In the developing world today, acute diarrhea strikes more than one billion humans every year, and leaves more than five million dead, usually the very young. Diarrhea remains one of the two most common medical complaints of humanity.
"Frequent passage of unformed watery bowel movements," as described by Taver's Cyclopedic Medical Dictionary, diarrhea falls into two broad types: invasive and non-invasive. From bacterial sources, invasive diarrhea, sometimes called "dysentery," attacks the lower intestinal wall causing inflammation, abscesses, and ulcers that may lead to mucus and blood (often "black blood" from the action of digestive juices) in the stools, high fever, "stomach" crams from the depths of hell, and significant amounts of body fluid rushing from the patient's nether region. 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.

单选题 In Paragraph 1, the author uses the quoted word "grief" from Shakespeare to refer to ______.
A. the terrible weather B. the stern army life
C. the suffering from diarrhea D. the tough wartime
【正确答案】 C
【答案解析】本题问第一段中作者引用莎土比亚的“grief”一词来指什么。第一段描写腹泻的过程:在漫漫长夜里,同样的场面重复了一次又一次:钻出睡袋,跑出帐篷,飞快地冲、蹲,匆匆赶回。莎士比亚写到:没在遭受痛苦的人都说自己能战胜痛苦,只有那受苦之人才难堪其苦。第二段指出这就是腹泻。所以正确答案是C(腹泻之苦)。
单选题 According to the description in Paragraph1, which of the following did the author NOT do at that time?
A. withstanding the coldness B. Camping in the mountains
C. Getting up repeatedly at night D. Reading Shakespeare in bed
【正确答案】 D
【答案解析】根据第一段的描写,主人翁只是想到了莎士比亚的话,并不是那天在床上读莎士比亚的作品。所以正确答案是D。
单选题 Who first gave the disease the name "diarrhea"?
A. Ancient Egyptians B. An old Greek
C. American soldiers D. The passage doesn't tell
【正确答案】 D
【答案解析】古埃及的医生们甚至在古希腊长老给这个病起了个几乎没人能拼写正确的名字之前就在纸草上记载了法老的痛苦之状。所以D是正确答案,即文章没有提到是谁用diarrhea这个现代术语命名这个病的。
单选题 According to Paragraph 2 ______.
A. people of higher status are less likely to be stricken with diarrhea
B. diarrhea is no longer a serious disease in the modem world
C. diarrhea has been a threat to humanity throughout history
D. the elderly are more likely attacked by diarrhea than the young
【正确答案】 C
【答案解析】“自从有史学家记载以来,腹泻就令国王、平民、妇女、儿童都病倒过。…在当今世界,……腹泻仍然是人类两大最为普遍的疾病之一。”所以正确答案是C(有史以来,腹泻一直给人类造成威胁)。
单选题 The invasive diarrhea and the non-invasive diarrhea are different in that ______.
A. the former attacks the intestine walls but the latter does not
B. the former causes dehydration but the latter does not
C. the former makes the patient physically weaker than the latter
D. the former is more dangerous than the latter
【正确答案】 A
【答案解析】“痢疾性腹泻侵袭下肠壁,引起发炎、脓肿和溃疡,……非痢疾性腹泻……但不侵袭肠壁。菌落释放的毒素引起痉挛、恶心、呕吐。”所以A(前者侵袭肠壁而后者不)是正确答案。
