填空题和选择题一样 ,是各类考试中最常见的题型 ,但填空题较选择题而言 ,难度较大 ,没有选择支提供解题的信息 ,且计算或判断后无法确定正误 .这也并不是说填空题和选择题毫无关系 ,事实上 ,填空题和选择题像一对孪生兄弟 ,出现在各类考试中 ,并且它们在解法上也有很大的相似 Filling in the blanks and multiple choice questions are the most common types of questions in various examinations. However, filling in blanks is more difficult than selecting multiple-choice questions. There is no choice to provide information for solving questions, and calculations or judgments cannot be used to determine correctness. Nor does it mean that the answer to the blank has nothing to do with the multiple-choice questions. In fact, the fill-in questions and multiple choice questions are like twin brothers. They appear on various examinations and they have very similar solutions.
