这句话中，paint是不带to的不定式，作宾语补足语。新课讲授4a不定式作宾语补足语

在英语中，有些句子只有宾语并不能表达完整的意思，还必须在宾语后面加上宾语补足语才能表达完整的意思。宾语补足语通常位于宾语之后。我们把“宾语+宾语补足语”称为复合宾语。例如：Myfatherencouragesme

toplaytheguitar.Themanageraskedhim

towait.Theteachertellsthestudents

nottocheatintheexam.Theyoftentellme

nottogetclosetostrangers.宾语是动作的执行者Grammar1当不定式作宾语补足语时，分带to的不定式作宾补和不带to的不定式作宾语两种情况。常见的用带to的不定式作宾补的动词（短语）有：ask,advice,allow,encourage,get,order,require,teach,tell,want,wish,expect,warn,permit,force等。常见的用不带to的不定式作宾补的动词（短语）有：“一感”feel；“二听”hear,listento；“三使”let,have,make；“五看”see,watch,notice,observe,lookat;“半帮助”help接不定式作宾补，加不加to都可以。不定式作状语

状语用来修饰动词、形容词或副词。它表示行为发生的时间、地点、目的、方式、原因、程度等意义，一般由副词、介词、介词短语、不定式、从句或相当于副词的词或短语来担任。不定式作状语时，多至于句末。但为了加强语气，突出表示目的，不定式（尤其是不定式短语inorderto）可放在句首。例如：(Inorder)to
