考研英语二31题答案：Based on the given context, the correct answer is likely to be a verb that best fits the sentence structure and conveys the intended meaning. However, without the actual question and options, I can only speculate. If the sentence is about a person's action or a process, a verb like "has been" or "is" might be appropriate. For example, "He has been studying for the exam." If it's about a general fact or condition, a verb like "is" could be used, as in "It is important to prepare well." Please provide the full question and options for an accurate answer.
