737. The United Parcel Service plans to convert its more than 2,000 gasoline-powered trucks in the Los Angeles area to run on cleaner-burning natural gas.
A. to convert its more than 2,000 gasoline-powered trucks in the Los Angeles area to
B. to convert its more than 2,000 trucks in the Los Angeles area that are powered by gasoline to
C. on converting its more than 2,000 gasoline-powered trucks in the Los Angeles area that will
D. for its more than 2,000 gasoline-powered trucks in the Los Angeles area to convert to
E. that its more than 2,000 trucks in the Los Angeles area that are powered by gasoline will convert to
解析：
A选项plan to do，convert .....to do sth，表达都是正确的
B选项后面有个that定语从句会很啰嗦，直接用gasoline-powered trucks这个表达就可以
C选项plan on doing表达是正确的，that定语从句可能会修饰就近名词area的歧义
D选项for its more than 2,000 gasoline-powered trucks很啰嗦，不用说“为了2000辆卡车.....”直接说“将2000辆卡车转换至....”就行
E选项用gasoline-powered会更简洁，plans后面跟了个that宾语从句也很啰嗦，没有plan to do直接
答案：A
