## 语法题目 ## **介词和连词第4题** A floodplain is an extension of a river channel, ____ not inundated except during a flood. A. where is it B. but it is C. or is D. in case it ## 题目解析 ## 参考答案: B 答案解析：空格后不是一个完整的句子，需要将句子补充完整或者填入其他词连同后面的部分做状语，根据选项判断，将句子补充完整，A语序不对，C缺少主语，D缺少谓语，选择 B。翻译：漫滩是河流河床的扩展，但是只有在有洪水的时候才会被淹没。 ## 解题思路逗号前是一个主谓结构完整的句子，逗号后的内容并不是一个名词或者名词性短语，故推测逗号后的内容可能是由连词连接的一个从句，故空格处应该填入的内容的结构应该是「并列连词/从属连词 + 主语 + 助动词」。A 选项中的 where 和 D 选项中的 in case 都是从属连词，B 选项中的 but 和 C 选项中的 or 都是并列连词。其中 A 选项的语序错误，因为从句的语序应该是陈述语序；C和D 两个选项分别缺少主语和助动词，故排除；B 选项符合结构要求，且根据句意，逗号前后的内容存在转折关系，故本题答案为 B 选项。 ## 知识点梳理 ## **介词** 介词是英语词类中的一种虚词，不能独立在句中充当句子成分。但介词与其宾语一起构成介词短语以后，就可以在句中充当多种句子成分，可以作主语、补足语、定语和状语等。介词的作用：介词是把名词与动词、形容词或另外的名词连接起来，以表示前后词语之间的关系。常见介词：at, by, for, from, in, near, of, off, on, during, since, before, after, until; inside, out of, within, without, outside, throughout; as to, until after, except for; at the cost of, at the mercy of, by means of, in place of, by favor of, in spite of, in/with reference to, in/with regard with ① I have lived here for a year. ② I'll wait for you till 10 o'clock. ③ I was familiar with nobody at the meeting. ④ Swimming is good for your health. ⑤ We can see with our eyes and write with our hands. ⑥ We succeeded by cooperating with them. ⑦ She seems to know the solution to the problem. **连词** 连词是英语词类中的一种虚词，不能独立在句中充当句子成分，但可以起连接作用，即连接词与词或句与句。连词有两类：从属连词和并列连词。从属连词都引导从句，比如状语从句、定语从句等；并列连词可以连接两个互不依从的词、短语或分句。常见从属连词：when, while, as, before, after, until, till, since, if, unless, so that, because, although 等常见并列连词：and, or, but, yet, for, either…or, both…and, not only…but also, as well as, neither…nor 等 ① When he comes I'll tell him about it. ② I wasn't long before he told us about it. ③ We danced and danced until they all joined in. ④ He was worried because he hadn't had any letter from her. ⑤ Although everyone played well, we lost the game. ⑥ We were singing and dancing all evening. ⑦ She has been learning English for six years, but she doesn't speak it very well. ⑧ The days were short, for it was now December.
