緊縮定語(yǔ)從句就是指把一個(gè)定語(yǔ)從句緊縮成“ 介詞+關(guān)系代詞+不定式”結(jié)構(gòu).這類(lèi)結(jié)構(gòu)主要用于正式文體中.
She must have time in which she can grow calm.=She must have time in which to grow calm.
她必須有冷靜下來(lái)時(shí)的時(shí)間.
Allow me one minute in which I can change my clothes. =Allow me one minute in which to change my clothes.
給我一點(diǎn)時(shí)間換衣服
He was miserable unless he had neighbors with whom he could quarrel.=He was miserable unless he had neighbors with whom to quarrel.
他要是沒(méi)有鄰居吵架就難受.
若語(yǔ)義清楚,且結(jié)構(gòu)恰當(dāng),“介詞+關(guān)系代詞+不定式”結(jié)構(gòu)有時(shí)可進(jìn)一步將其中的關(guān)系代詞省略,而只保留介詞和不定式（介詞要移至不定式之后,且當(dāng)先行詞為表時(shí)間的名詞時(shí),該介詞通常省略）
She must have time to grow calm (in).
她必須有冷靜下來(lái)時(shí)的時(shí)間.
Allow me one minute to change my clothes (in).
