【AEAS培训网】AEAS语法中从句之状语从句的知识引导
AEAS培训网在本文主要针对从句知识点的归纳整理。此类从句题型主要考查的是考生对各种从句的构成和用法的理解与掌握。AEAS考试中常出现的从句类考题主要包括对状语从句、宾语从句和定语从句的考察。
同学们在AEAS考试中遇到从句类型题，做题前应先判断此从句属于哪一类型，再根据不同从句的类型判断选项。分清限定性定语从句和非限定性定语从句中不同关系词的用法。
例如：She has found the necklace that she lost two weeks ago.(限定性定语从句)
He didn’t seem to understand me, which greatly upset me. (非限定性定语从句)
判定的首要依据是逗号的使用，关系代词that不能用于非限定性定语从句。
要注意从句与主语之间的时态关系。比如，在时间状语从句中，当主语是一般将来时或祈使句时，从句用一般现在时;在宾语从句中，主句与从句时态要保持一致。
常见的状语从句知识点归纳如下：
状语从句在主从复合句中修饰主句中的动词、形容词或副词等。状语从句由从属连词引导，与主句连接，即可为于句首，也可位于句末。位于句首时，状语从句常用都好与主句分开;位于句末时，一般与主句连接，不用逗号分开。状语从句主要考查的类型大致如下：
