1.當主句謂語動詞是find,see,watch,hear等感官動詞時,從句常簡化為“賓語+賓補”結構,賓補為不帶to的不定式或V-ing形式。如:
Shefoundthatthewalletlay/waslyingontheground.→Shefoundthewalletlie/lyingontheground.
2.當主句謂語動詞是hope,wish,decide,forget,plan,agree等,且主句主語與從句主語相同時,從句可簡化為不定式結構。如:
Sheagreedthatshecouldhelpmewithmymaths.→Sheagreedtohelpmewithmymaths.
3.在連接代詞/副詞引導的賓語從句中,當從句主語與主句主語或間接賓語一致時,賓語從句可簡化為“連接代詞/副詞+不定式”結構。如:
CanyoutellmehowIcangettothestation?→Canyoutellmehowtogettothestation?
