Question

Students in English-speaking countries usually address their man teacher ‘sir”, but __________ their woman teacher “madam”.

A．seldom they address	B．do they seldom address
C．seldom do they address	D．they seldom do address

Answer 1

C

試題分析：seldom很少，否定含義，放在句首，句中的主謂要用倒裝結(jié)構(gòu)。句意：講英語國家的學(xué)生通常尊稱其男教師為“先生”，但很少稱其女教師為“女士”。
點評：掌握英語中否定詞放在句首，句子結(jié)構(gòu)要主謂倒裝。hardly, in no way, little, scarcely, seldom, never, no more, no longer, not, not only, no sooner, not only … (but also),not until… 等具有否定意義的詞或詞組位于句首，句子用部分倒裝。部分倒裝：指將謂語的一部分如助動詞或情態(tài)動詞倒裝至主語之前,而謂語動詞無變化。如果句中的謂語沒有助動詞或情態(tài)動詞，則需添加助動詞do, does或did，并將其置于主語之前。eg：
No sooner had I got home then it began to rain. 我剛到家就下起了雨。
Seldom do I go to work by bus. 我很少乘公共汽車上班。
Not until twelve o'clock did she go to bed last night . 她昨晚十二點才上床睡覺。
