I must apologize for not letting you know earlier. 句子成分分析,另外为什么know不用非谓语形态,是做谓语?
答
I (主语)must apologize(谓语) for not letting you know earlier(介词短语做原因状语)
介词短语结构分析:
for (介词)not letting you know earlier(动名词短语作介词for 的宾语)
动名词短语结构分析:
not letting (动名词)you (动名词的宾语)know earlier(不带to的不定式做宾补)
let ,make,have,see,hear,notice,watch,等词后面不定式做宾补时要省to,即“动词原形”
