SARS — Severe Acute Respiratory Syndrome — was【C1】______for the first time in February 2003 in Hanoi, 【C2】______since then has infected more than 1, 600 people in 15 countries, killing 63. At this【C3】______there are more questions than answers surrounding the disease.
Symptoms start【C4】______a fever over 100. 4 degrees F, chills, headache or body【C5】______Within a week, the patient has a dry cough, which might【C6】______to shortness of breath. In 10% to 20% of cases, patients require【C7】______ventilation to breathe. About 3.5% die from the disease. Symptoms【C8】______begin in two to seven days, but some reports suggest it【C9】______take as long as 10 days. Scientists are close to【C10】______a lab test to diagnose SARS.

选项
A、probably
B、obviously
C、unlikely
D、clearly
答案
C
解析
逻辑衔接题。注意空格所在句的衔接词though表示前后有让步关系,上一句说明病毒停留在物体表面,人们通过接触而传染。既然是让步关系.那么本句耍表达的意思是与患者同乘一电梯就会传染病毒还不太可能,所以选[C]。若选其他三项,则不符合上下文的逻辑关系。
