One impediment ________ the general use of a standard in pronunciation is the fact ________ pronunciation is learnt naturally and unconsciously, while orthography is learnt deliberately and consciously.
问题1选项
A.in...which
B.of...in which
C.on...that
D.to…that
【选项释义】 A. in... which B. of... in which C. on... that D. to… that 【考查点】固定搭配和同位语从句。 【解题思路】impediment to sth.是固定搭配，意为“……的障碍”，所以第一空填to。pronunciation is learnt naturally and unconsciously, while orthography is learnt deliberately and consciously（发音是自然地无意识地学到的，而拼写是刻意的有意识地学到的）是fact的同位语，表示该事实是什么，所以第二空为that引导同位语从句。因此D选项正确。 【干扰项排除】 A、B、C选项均不符合此处固定搭配和同位语从句引导词。 【句意】阻碍标准发音的广泛使用的一个事实是，发音是自然地无意识地学到的，而拼写是刻意的有意识地学到的。
