1.(2015·北京,33改编)I truly believe________beauty comes from within.
答案:that 考查名词性从句引导词。从句部分不缺少任何成分也不缺意思。因此用只起连接作用的that。
2.(2015·陕西,19改编)Reading her biography,I was lost in admiration for ________Doris Lessing had achieved in literature.
答案:what 考查宾语从句中引导词的选择。分析语境可知,此处是介词for后接了宾语从句。从句中缺少achieved的宾语,故要用what来引导。句意:读她的传记,我对多丽丝·莱辛在文学上所取得的成就钦佩不已。
3.(2015·安徽,25改编)A ship in harbor is safe,but that's not ________ ships are built for.
答案:what what引导表语从句,在从句中作介词for的宾语。句意:船停泊在港口里是安全的,但那可不是造船的目的。
