21、例1：With their shining brown eyes，wagging tails and unconditional love dogs can provide the nonjudgmental listeners needed for a beginning reader to gain confidence，according to Intermountain Therapy Animals(ITA)in Salt Lake City.点拨：该句含33个单词，理解难度也很大。分析语境和句子成分可知，With their shining brown eyes，wagging t

22、ails and unconditional love为with复合结构作原因状语，needed for a beginning reader to gain confidence为过去分词作后置定语修饰listeners，according to Intermountain Therapy Animals(ITA)in Salt Lake City为介词短语作条件状语。句意为：根据盐湖城ITA(的结论),这种狗长着明亮的棕色眼睛,摇动着尾巴，拥有不附加任何条件的爱心。因此，这种狗可作为初学者获取自信心，而且不会妄加评判的忠实听众。技巧二：抓句子核心成分，简化长句 分析长难句的核心成分，从句子

23、层次入手，先抓主干，再理枝叶。例2：I am always amazed when I hear people saying that sport creates good will between the nations，and that if only the common people of the world could meet one another at football or cricket，they would have no inclination to meet on the battlefield.点拨：该句为主从复合句，主句为I am always amazed，整个

24、后面部分为时间状语；在时间状语中，分词saying带有两个that引导的宾语从句，与saying一齐构成分词结构作people的补语；在第二个宾语从句中，又有一个主从复合句，其中they would have no inclination to meet on the battlefield为主句，分句if only.or cricket是条件状语从句。句意为：人们说体育运动可创造国家之间的友谊，还说如果各国民众在足球场上交过手，就不愿在战场上互相厮杀。每当我听到这么说时总是惊愕不已。技巧三：用单句重排法准确理解复合句 当复合句中有很多从句叠现时，可以用单句重排法进行简化。例3：Literac

25、y specialists admit that children who read below the level of their fellow pupils are often afraid of reading aloud in a group，often have lower selfrespect，and regard reading as a headache.点拨：分析语境逻辑及句子结构可知，that引导宾语从句，宾语从句的主语又带一个who引导的定语从句，宾语从句的谓语由三个并列动词构成，分别为are often afraid of，often have，and regard

26、可排成单句，简化如下：1In the opinion of specialists，some children read below the level of their fellow pupils.2They are often afraid of reading aloud in a group.3They often have lower selfrespect.4They regard reading as a headache.句意因此明朗了：一些读写专家认为，有些阅读能力低于同龄人的孩子不爱在小孩群里高声朗读，他们自尊心很强，常将读书看成头痛的事。技巧四：用还原法恢复句子原貌 追根求源，恢复其本来面貌，是我们准确理解长难句的好方法。例4：Excused from recycling because you live in a high rise with a rubbish chute(垃圾道)?点拨：该句为省略句，可还原为：Are you excused from recycling because you live in a high rise with a rubbish chute？住在有垃圾道的高楼上就可以不参与回收利用垃圾吗？
