单选题 The doctors ______the newly approved drug into the patient when he was critically ill.
A. injected B. rejected C. projected D. subjected

【正确答案】 A

【答案解析】inject意为“注射，注入”，通常与into搭配使用；reject意为“拒绝，抵制”； project意为“计划，设计”；subject意为“使屈从于，使隶属”。所填之词的宾语是the newly approved drug，根据后面的into the patient可知，应选inject。
