【正确答案】
A
【答案解析】speculate 表示“推测、推断”的意思;estimate意为“估计”,如:Now I've realized that my estimate of her character was one-sided.现在我认识到我对她品格的评价是片面的。evaluate 意为“评估”、“评价”,如:The research project has only been under way for three months,so it's too early to evaluate its success.这个研究项目进行了不过三个月,所以要对它的成绩作出评价为时尚早。anticipate意为“预期”、“预料”。
