  一、 现在分词作定语
  现在分词作定语时,一般可转换成定语从句。例如:
  The wild flowers looked like a soft orange blanket ________ the desert. (2006湖南)
  A. covering B. covered
  C. cover D. to cover
  简析: 答案是A。a soft orange blanket与cover存在主谓关系,因此要用现在分词作谓语,它相当于定语从句which / that covered。而不定式作定语一般表示将要发生的动作,故不能误选D。
  高考衔接:
  The flowers________sweet in the botanical garden attract the visitors to the beauty of nature. (2004年上海卷)
  A. to smell B. smelling
  C. smelt D. to be smelt
  简析: 答案是B。smelling sweet in the botanic garden在句中作定语,修饰the flowers。smell在此处为系动词,意思为“闻起来发出……的味道”,不使用被动语态。
  动名词与现在分词作定语时的比较
  1. 动名词作定语时,表示它所修饰的名词的性能和用途,它和所修饰的名词在逻辑上没有主谓关系;现在分词作定语时,表示它所修饰的名词正在进行的动作,它和所修饰的名词在逻辑上有主谓关系,常可以扩展成一个定语从句。例如:
  a swimming girl = a girl who is swimming一个在游泳的姑娘 (现在分词)
  a walking stick = a stick that is used for walking一根拐杖 (动名词)
  高考衔接:
  1. Will those________the children from abroad come to the headmaster’s office? (2000上海春)
  A. teaching B. teach
  C. who teaches D. who teaching
  简析: 答案是A。此处表主动,故用现在分词,注意若选C项应把teaches改成teach。也可改成定语从句those whoteach the children from abroad。
  2. There are hundreds of visitors________in front of the Art Gallery to have a look at Van Gogh’s paintings.
  A. waited B. to wait
  C. waiting D. wait
  简析: 答案是C。题中动词的现在分词作定语。
  3.________the meeting himself gave them a great deal of encouragement. (2003上海春)
  A. The president will attend
  B. The president to attend
  C. The president attended
  D. The president’s attending
  简析: 答案是D。句中谓语动词为gave,其前内容只能为主语,故此时只能用动名词复合结构作主语。
  
  二、 现在分词作补足语
  现在分词可作宾语补足语和主语补足语。此时句中的谓语动词多为表示感觉的动词、短语动词或使役动词。例如: see,hear,watch,notice,observe,find,smell,look at,listen to,have,get,set,catch,keep,leave等。现在分词作补语时往往表示动作正在进行。
  高考衔接:
  1. —Why did you go back to the shop?
   —I left my friend________there. (2003安徽春)
  A. waiting B. to wait
  C. wait D. waits
  简析: 答案是A。现在分词作宾语补足语。
  2. Don’t leave the water________while you brush your teeth. (2004天津)
  A. run B. running
  C. being run D. to run
  简析: 答案是B。leave sb. / sth. doing是固定句型,意为“使/让某人/某物一直(干) ……”。leave在这里的意思是“使(让)”的意思。
  3. A cook will be immediately fired if he is found________in the kitchen. (2003全国)
  A. smoke B. smoking
  C. to smoke D. smoked
  简析: 答案是B。根据句意和感官动词find的用法要求,此题的正确答案应为B。smoking作主语a cook的补足语。
  
  三、 现在分词作表语
  现在分词作表语通常表示主语的性质或状态,是一种系表结构。作表语常见的有exciting, moving, inspiring, missing, interesting,
  disappointing等,表示“令人感到……,使人感到……”。例如:
  I find it hard to learn English.我发现学英语很难。
  高考衔接:
  I found the game excited, and my dad explained for the rules. (2005浙江卷短文改错)
  简析: 发现游戏有趣,故把excited改成exciting。
  动名词与现在分词作表语时的比较
  1. 动名词作表语往往用于说明主语的内容,回答what的问题;现在分词作表语相当于形容词作表语,往往说明主语的性质、特征等,常用于回答how的问题。例如:
  ① What pleases him most is bathing in the sea.最使他高兴的事是在海中沐浴。(动名词)
  ② The situation both at home and abroad is very inspiring.国内外的形势都很鼓舞人心。(现在分词)
  2. 动名词作表语时,表语和主语几乎处于同等地位,可以互换位置,其句意不变;现在分词作表语时,表语和主语则不能互换位置。例如:
  ① Our work is serving the people.(=Serving the people is our work.)我们的工作是为人民服务。
  ② The news was disappointing.那消息令人失望。
  3. 作表语的现在分词前可以用very,quite,rather,greatly等副词修饰,而动名词则不可以。例如:
  ① What he said was very encouraging.他的话很鼓舞人心。
  ② Our goal is realizing the four modernizations in the near future.我们的目标是在不久的将来实现四个现代化。
  4. 现在分词与形容词一样可以和more,the most构成形容词的比较级和最高级,而动名词则不可以。例如:
  The story is the most fascinating.那个故事最迷人。
  5. 作表语用的现在分词除了和be连用以外,还可以和其它的系动词连用;而作表语的动名词则通常只能和be连用。例如:
  ① His speech seems inspiring.他的演讲似乎很鼓舞人心。(现在分词)
  ② His interest is writing for the newspapers.他的爱好是给报社写文章。(动名词)
  6. 有些用作表语的现在分词已经形容词化了。常见的有: exciting,moving,inspiring,missing,interesting,disappointing等。
  
  四、 现在分词作状语
  -ing形式作状语可以表示时间、原因、结果、条件、让步、行为、方式、伴随状况等。
  高考衔接:
  When________different cultures, we often pay attention only to the differences without noticing the many similarities. (2006浙江)
  A. compared B. being compared
  C. comparing D. having compared
  简析: 答案是C。we和compare是主动关系,故用现在分词作状语。
  学习-ing形式作状语的用法时,需要注意以下三点:
  1. 与过去分词作状语的区别。一般来说,-ing形式表示语态上的主动、时态上的进行;过去分词表示语态上的被动、时态上完成。试比较:
  The enemy fled in a panic, leaving behind a lot of dead bodies and weapons.
  Defeated and frightened, the enemy fled in a panic.
  简析: 前一例中的-ing形式短语在句子中作伴随状语,它与其逻辑主语the enemy之间为主动关系;后一句中的过去分词defeated和frightened表原因。
  2. 关于逻辑主语的问题。-ing形式作状语时,一般情况下,其逻辑主语应与主句的主语保持一致。例如:
  Comparing all the great people with each other, you’ll find that they have much in common.
  Finding her car stolen, she hurried to a policeman for help. (上海 2001)
  Having suffered from heart trouble for years, professor White has to take some medicine with him wherever he goes. (上海 2001春)
  简析: 以上-ing形式的逻辑主语均为主句的主语。
  3. –ing形式(短语)的功能有时相当于一个状语从句,根据这个性质,我们在使用-ing形式作状语时,切记不要在前面或后面的句子前用连词连接。例如:
  Walking on the fallen leaves in autumn, so you’ll feel very comfortable.
  简析: 如前所述,-ing形式短语相当于一个状语从句,所以后半句中的连词so的使用是错误的,应该去掉。原句应改为:Walking on the fallen leaves in autumn, you’ll feel very comfortable.
  高考衔接:
  1. More and more people are signing up for Yoga classes nowadays,________advantage of the health and relaxation benefits. (2005上海卷)
  A. taking B. taken
  C. having taken D. having been taken
  简析: 答案是A。检查考生对非谓语动词作状语的掌握和运用能力。take advantage of(利用)和句子主语More and more people构成主动关系,且和句子谓语sign up for(报名参加)同时发生,所以选择A。
  2. Daddy didn’t mind what we were doing, as long as we were together,________fun. (2005重庆卷)
  A. had B. have
  C. to have D. having
  简析: 答案是D。现在分词作状语表伴随的动作。
  3. Oil prices have risen by 32 percent since the start of the year,________a record US $57.65 a barrel on April 4. (2005山东卷)
  A. have reached B. reaching
  C. to reach D. to be reaching
  简析: 答案是B。现在分词作状语表伴随的动作。
  4. He glanced over at her,________that though she was tiny, she seemed very well put together. (2005广东卷)
  A. noting B. noted
  C. to note D. having noted
  简析: 答案是B。现在分词作状语表伴随的动作。
  5. Having been attacked by terrorists,______. (2004上海)
  A. doctors came to their rescue
  B. the tall building collapsed
  C. an emergency measure was taken
  D. warnings were given to tourists
  简析: 答案是A。Having been attacked by terrorists为分词短语,作全句的状语,其逻辑主语应与句子主语一致,故选B。
  6. Alice returned from the manager’s office,________me that the boss wanted to see me at once. (2004全国Ⅳ)
  A. having told B. tells
  C. to tell D. telling
  简析: 答案是D。现在分词作状语表伴随的动作。
  7. “We can’t go out in this weather,” said Bob,________out of the window. (2004全国Ⅱ)
  A. looking B. to look
  C. looked D. having looked
  简析: 答案是A。looking out of the window作said的伴随状语。Bob与look是主谓关系,所以此处作状语的分词应用现在分词。
