1.(常考题：并列)Nurses and anesthesiologists are both essential in the operating room,and the anesthesiologists would keep the patient sedated while the nurses would assist and support the surgeon.

the anesthesiologists to keep the patient sedated and the nurses to assist and support

点评：anesthesiologists和nurses为并列关系，所以用“…to… and…to…”避免run-on。记住这种形式，考得比较多，大家做题时多注意类似题目

2.The sausage served at the end of the meal was more flavorful than any of the other pastas I had tasted;probably because it was roasted in its own juices.

was more flavorful than any of the pastas I had tasted,probably because

点评：pastas不是sausage，故谈到pastas用“any of pastas”不用“any other”。由于后半句谈原因，所以和前面是有联系的，中间用逗号。

the hawks,after several books were written about them,became such an attraction that

由于最后代词是“them”，可见所指为复数名词。而第一句主语为nest, 所以可见第二局主语不是网而是鹰。故正确答案不用代词为主语，而是将“they”指明，换成“hawks”

are that they have challenging research to complete and must also work hard to hold student interest

点评：主谓一致性要保持，同时使用并列结构。

6.Having achieved fame, widespread acclaim,as well as continued relevance,DS is considered to be a classic American movie.

Having achieved fame,widespread acclaim,and continued relevance

点评：用动名词“Having”没错。但能用and就不用as well as(这似乎又是一条规律)，and前有无逗号无所谓。

7.For as many as 9 months or more,Thad Carthart lived in Paris.

For more than 9 months

点评：不说了，简洁为上!九个月或九个月以上就是“九个月以上”

8.Many home owners in the northern states use a window sealant,for it will prevent heat loss in the winter.

点评：谈原因，从句有时候更简洁。

9.The runners coming this far,they decided to push through the very strenuous final mile of the marathon.

Having come this far,the runners

点评：记住这个句式，Having done sth,XX…不是说它有知识上的意义(大家肯定早就知道了)，只是说它正确的频率相当高。同时原句没有转折语气就不要用转折词。
