大部分单项填空题由两部分组成:空格句和附加句。空格句指空格所在的句子,附加句指空格所在句子之外的句子,如分句、从句、主句、独立句等。单项填空题所设的四个选项可能有几个或全部满足空格句结构的需要,并使空格句有意义。只有与附加句结合,综合分析后,我们才能确定唯一正确的选项。因此,试题中的附加句是有意设计的,对判 Most of the single-entry questions consist of two parts: vacancies and additional sentences. The space sentence refers to the sentence where the space is located, and the additional sentence refers to the sentence other than the sentence where the space is located, such as a clause, a clause, a main sentence, an independent sentence, and the like. The four options provided for the individual fill-in questions may have several or all of the requirements for the structure of the space sentence and make the space sentence meaningful. Only when combined with additional sentences and comprehensive analysis can we determine the only correct option. Therefore, the additional sentence in the test question is intentionally designed and judged.
