16.FortunatelyFortunately解析:由本句句意“…可以看到有解决办法的希望了。”可知,此空应填“幸运的是”。
17.workwork解析:本句意为“我们以前已经尝试过,但是不…。”显然,此空处应填“奏效,起作用”,英语中表达这一含义最地道的词就是work。
18.whichwhich解析:由此句句子成分分析,此空以后的应为定语从句,修饰characteristics,所以此空应填which,引导定语从句。
19.someonesomeone解析:由本文的第一句话“‘Down-to-earth’meanssomeoneorsomethingthatishonest.realisticandeasytodealwith.”可知“Down-to-earth”指的是诚实,现实、平易近人的那些人。这里的someone和后面是相对应的。故答案为someone。
20.oppositeopposite解析:从文章第二段的内容可以看出,Adown-to-earthperson和那些表面上装的很重要的人物正好相反。所以这里应填“相反的”,故答案为opposite。
21.readyready解析:顾客来到结算处,说明他们准备好了要付账。bereadyto的意思是“准备好了做某事”。故答案为ready。
22.ratherrather解析:此空所在句意为“用四个手指握笔而不是三个。”ratherthan表示“而不是”。
