2024年中考英语：必考连词一篇搞定
连词
是一种在句子与句子之间，短语之间以及名词等其他词语之间起连接作用的虚词，它不能单独作句子的成份。按其意义可分为并列连词和从属连词两大类。
常有的并列连词有
并列连词连接的双方是对等的。and, both…and, either…or, neither…nor， not only…but also, as well as等。但如果连接的两部分意义不趋向一致，：but, however, while (而)，only (只不过)。
还有表示选择关系的并列连词，
如：or, or else, otherwise… 再有的是连接双方，互为因果，或表示前因后果的连词有：for, so, therefore (因此)，then等。
从属连词在初中范围内常常用来连接名词性从句，
如：that, if, whether, 其次用来连接状语从句。：when , while, as, since, before, after, once, as soon as, until, till。
连接条件状语的连词有：
if, unless, as long as 等，because, since, as, now that (既然)。so that, so…that, such…that, as…as, than, where… 它们在句子与文章中几乎无处不见。
