1个回答

__Only___by keeping down costs will Power Data hold its advantage over other companies.

倒装句:且keeping down costs 与Power Data hold its advantage over other companies为因果关系.四个选项中只有only合适.相当于汉语的“只有...才能.”

第二题:

Captain Scott’s example__inspired_____them with the determination to reach the South Pole on foot .

根据单词意思即可排除respected和admired,那么就看是选inspired还是prepared.

根据以下介词搭配:

prepare for 为...作准备

inspire sb.with sth.使某人产生某种感情; 激发某人的某种感情
