填空要做到完整不出意外，按以下三步走。

　　一、定性。空格要求什么性质的东西。是一个词、短语、还是从句等。还要分清性质，是名词性动词性还是形容词性等，填的时候对症下药。

　　二、定位。这一步跟前面是通用的。

　　三、基本照抄。原文照搬即可。问题是抄哪一部分，哪几个词，取决于第一步定性的结果。

　　看真题。

　　8. The greatest benefit brought about by the interstate system was __________.来源：www.examda.com

　　9. Trucks using the interstate highways deliver more than ________________.

　　10. The interstate system was renamed after Eisenhower in recognition of ______________.

　　第八题是一个表语，名词性的，可能是词，短语或从句。原文是：

　　Above all,the interstate system provides individuals with what they enerish most:personal freedom of mobility.

　　不能填provide…, 这是个动词短语。后面what..引导的名词从句可以，冒号后名词短语是对这个名词从句内容的具体化，最好：personal freedom of mobility.

　　第九题填deliver的宾语，要填一个含数字的名词短语。

　　The interstate system has been an essential element of the nation's economic growth in terms of shipping and job creation:more than 75 percent of the nation's freight deliveries arrive by truck.and most products that arrive by rail or air use interstates for the last leg of the journey by vehicle.

　　从75开始的名词短语是：75 percent of the nation’s freight deliveries, deliveries与题中的deliver重复，去掉。

　　第十题，介词之后，名词短语。

　　The high way system was officially renamed for Eisenhower to honor his vison and leadership.

　　不能从to honor截取，它是动词不定式短语，不能作介词宾语，后面his vision and leadership才是。来源：www.examda.com
