試題分析：考察部分倒裝。本題考察的是否定詞放在句首構(gòu)成的部分倒裝。
1) 以否定詞開(kāi)頭的句子要求部分倒裝。注意下列句子中助動(dòng)詞或情態(tài)動(dòng)詞提前、甚至補(bǔ)充助動(dòng)詞的用法：
例：Not until yesterday did little John change his mind.（小約翰直到昨天才改變了主意。）
In no country other than Britain, it had been said, can one experience four seasons in the course of a single day.（據(jù)說(shuō)除了英國(guó)世界上沒(méi)有哪個(gè)國(guó)家能讓人在一天中感受到四季變化）
2) 以否定副詞開(kāi)頭并加狀語(yǔ)放在句首的句子要求部分倒裝。這些否定副詞有barely, hardly, little, seldom, scarcely…… when, never, no sooner…… than, rarely, no more, not nearly, not only等以及only。
Only in the country can you learn the “true English”.
3）一些如scarcely……when, no sooner ……than, hardly……when引導(dǎo)的主從復(fù)合句主句要求使用過(guò)去完成式。
本題中把not until the early years of the 19th centur放在了句首，故D正確。
