充不当什么意思
追答1. 宾语从句就是以一个“主+谓”结构充当宾语;如 I don't like ( that I am forced to learn.)
2. 表语从句就是以一个“主+谓”结构充当表语;如The question is (when we will have another chance).
3. 定语从句就是以一个“主+谓”结构充当定语;如 The man (who spoke to me just now) is our head teacher.
4. 当名词性从句中的谓语动词为不及物动词或虽为及物动词却带有自己的宾语且句子中缺少地点状语时,用where 来引导名词性从句。如:I don't know (where she has gone)
