分析句子成分 advertisements try to persuade people to buy things which they don’t really need.
advertisements try to persuade people to buy things which they don’t really need.
请问：这个句子如何按照句子结构划分?
Ad.这个是主语.
try 是谓语
try to do 的 to do 不定式作宾语么?
那persuade people 这里persuade 又是什么成分,
persuade sb to do
sb 是宾语,to do 是什么?
我很晕!
Ad.这个是主语；try 是谓语；to persuade people 不定式短语作宾语；persuade sb to do 其中的to do作宾语补足语.
