本句中使用了not only...but also...的倒装句式。not only...but also...如果引导两个并列的成分，就不必倒装。例如：
Not only Tom but also Jimmy is thought to have missed the chance to go to college. Clinton is not only intelligent but also hardworking.
但是，当not only...but also...的结构用来引导两个句子，且not only 放在句首的时候，前面的分句就要倒装。例如：
Not only does he like English，but also he learns it well.
思考：not only...but also...的结构中主谓一致的原则是什么？类似的情况试举两例。
________________________________________________________________________ ________________________________________________________________________ [答案]
遵循就近一致的原则，如neither...nor；either...or。 如：Not only you but also I am planning to go.

译：针灸是在身体一定的穴位插入不锈钢针来治疗疾病或解决健康问题。 [省略结构]
本句中a health problem solved是省略结构，其完整的句子为a health problem can be solved。两个并列分句中，后一个分句常省略与前一分句中相同的部分。
My father is a doctor and my mother (is) a nurse.
I study at college and my sister (studies) at high school. 趁热打铁
语法填空：
George said that he would come to school to see me the next day，but he ____________(do)． [答案与解析] didn't。考查动词的时态和省略。题干的意思是：乔治说他第二天会来学校看我，但是他没来。前一个分句的谓语动词said为一般过去时，空格处与said并列并作后一分句的谓语，并省略与前一分句中相同部分，故用一般过去时didn't。
