含有插入語的定語從句

1、1 The immediate cause of the protests - which seemed to receive some official encouragement -was the publication in Japan of revised junior-high-school textbooks that, the Chinese claim, whitewash Tokyo ' s World War record.2 The rapid decrease in bird population is partly due to the shrinking o

2、f lakes and wetlands, which scientists say are the paradise of many wading birds.3 The children of regular smokers are more likely to contract a range of lung diseases, which doctors believe are caused by breathing in too much environmental tobacco smoke. 1、as引導的短語或句子作插入語例句： The factors favoring uni

3、onization drives seem to have been either the presence of large numbers of workers, as in New York City,to make it worth the effort, or the concentration of small numbers in one or two locations, such as a hospital, to make it relatively easy. | 解析：這個句子中出現(xiàn)的兩處插入語都表示舉例，插入語后面接不定式表目的。本句中的 as后接的是介詞短語，插入語

4、比較短，有時候 as會引導一個句子，用來分散考生注意力。我們先把兩處插入語省略掉，句子變成 The factors favoring unionization drives seem to have been either the presence of large numbers of workers to make it worth the effort, or the concentration of small numbers in one or two locations to make it relatively easy. 這樣以來，either or表示的并列結(jié)構(gòu)就很清晰了。2

5、、介詞短語作插入語例句： Now Congress, in apparent agreement, has required by law that businesses awarded federal contracts of more than $500,000 do their best to find minority subcontractors and record their efforts to do so on forms filed with the government. 解析：本句的插入語出現(xiàn)在主語之后， 把主語和謂語分隔開來，這種插入語其實也可以和其他成分連接在一起，

6、用插入語的形式表現(xiàn)出來反而更分明一些。雖然插入語會使得考生思路被打斷，分散注意力，但在這種情況下它能成為一種信號，告訴考生這里可以暫時不讀，對句子結(jié)構(gòu)的理解不造成任何影響。本句的難點在于過去分詞作定語， 例如 business awarded federal contracts 和 forms filed with the government.3、非限制性定語從句 相當于插入語的功能例句： How such large creatures, which weighed in some cases as much as a piloted hang-glider and had wingspa

7、ns from 8 to 12 meters, solved the problems of powered flight, and exactly what these creatures were-reptiles or birds are among the questions scientists have puzzled over. 解析：非限制性定語從句與限制性定語從句的一個區(qū)別在于非限制性定語從句中和先行詞之 間只有比較松散的關(guān)系，出現(xiàn)在句中也是用逗號隔開，具有插入語的功能。我們先將插入部分略過不讀，很容易發(fā)現(xiàn)這是一個疑問句。特殊疑問詞 為how much和what,從本句還能看

8、出插入語的處理是非常靈活的，句中的 reptiles or birds也可以看成插入成分。非限制性定 語從句作插入語比較特殊的是弄清句子結(jié)構(gòu)之后再回頭看時，要與先行詞緊密對應。但是這只限于非限制性定語從句出現(xiàn)在句中的情況下，如果出現(xiàn)在句尾，就不能當作插入語。4、復雜名詞結(jié)構(gòu)作插入語例句：Increasingly, historians are blaming diseases imported fromthe Old World for the staggering disparity between the indigenous population of America in 1492 new estimates of which soar as high as 100 million, or approximately one-sixth of the human race at that time and the few million f
