(误)after his journey from abroad, richard jones returned home, exhausted.（正） her grandfather being ill, she had to stay at home looking after him(2) 作表语：一般来说，表示心理状态的动词如excite， interest等都是及物动词，汉语意思不是“激动”，“高兴”，而是“使激动”、“使高兴”，因而现在分词应该是“令人激动的”、“令人高兴的”，过去分词则是“感到激动的”和“感到高兴的”。所以，凡表示“令人的”都是-ing形式，凡是表示“感到”都用-ed形式。换句话说，-ed形式常和人有关，-ing形式常和物有关。look, expression等词作主语时常用-ed形式作表语，但有时要看具体情况。请在下面的几组句中体会他们的区别。e.g.:the news was very exciting. i was excited at it. the book is interesting.he is interested in it.the question is puzzling.his look is puzzledhis expression was frightening.i was frightened. 注意：delighting disappointing encouraging令人高兴的 令人失望的 令人鼓舞的pleasing satisfying令人愉快的 令人满意的delighted disappointed encouraged感到高兴的 感到失望的 感到鼓舞的pleased satisfied感到愉快的 感到满意的 surprising worrying tiring令人惊异的 令人担心的 令人疲倦的boring surprised worried令人厌烦的 感到惊异的 感到担心的tired bored感到疲倦 感到厌烦的(3) 作定语：过去分词做定语与其修饰词之间是动宾关系或过去分词表示的动作已完成；现在分词作定语表示动作正在发生，与修饰词是主谓关系。l the picture hanging on the wall is painted by my nephew.l the building being built is a hospital.l the flowers smelling sweet in the botanic garden attract the visitors to the beauty of nature.l linda worked for the minnesota manufacturing and mining company, known as 3m.l the key to solving the problem is to meet the demand made by the customers. l prices of daily goods bought through a computer can be lower than store prices. 注意：l i am interested in the interesting bookl he was excited at the exciting newsl the parents were disappointed about their l disappointing son. l mr. smith, tired of the boring speech, started to read a novel.(4)作补语：跟分词作宾补的动词有：catch, have get, keep, hear, find,feel, leave, make, want, start, notice, observe, watch, set等。在复合宾语中，用现在分词作宾补，说明宾语是动作的发出者，形成逻辑上的主谓关系；用过去分词作宾补，表示宾语是动作的承受者，构成逻辑上的动宾关系。 l there was so much noise that the speaker couldnt make himself heard.l when he awoke, he found himself being looked after by an old woman.l laws that punish parents for their little childrens actions against the laws get parents worried. note:非谓语动词使用条件: 一个句子当中，已经存在一个主句（谓语动词）,又没有连词的情况下, 还有别的动词出现时。并非分词的逻辑主语都要和句子的主语一致。此时的分词短语又可称为垂悬状语。有些动词不定式也可以这样运用。常见的这种情况有：e.g.:strictly speaking, smoking is not allowed here.judging from what he said, he is a southerner.taken as a whole, there is nothing important in his speech.to tell you the truth, i dont like english teacher.to speak frankly, i dont agree with you about the case.动词-ed的逻辑主语句子成分表语定语状语宾补逻辑主语句子的主语所修饰的词句子的主语句子的宾语链接高考1.“things _ never come again!” i couldnt help talking to myself. （2007湖南） a. lost b. losing c. to lose d. have lost 2. the flowers his friend gave him will die unless _ every day. （2007四川） a. watered b. watering c. water d. to water3. john received an invitation to dinner, and with his work ，he gladly accepted it. （2007安徽） a. finished b. finishing c. having finished d. was finished 4. he is very popular among his students as he always tries to make them _ in his lectures.
