I'll remember the time (______ we spent together in the country).
— ———— ———— ———————————————————
主語 謂語 賓語 定語從句
解析：主句：I'll remember the time.【賓語the time被后置定語(從句)限定】
從句：______ we spent together in the country.
— —— ——————————
主語 謂語 狀語
從成分可以看出：從句缺賓語,應(yīng)該是spent (the time→that/which),代詞提前引導(dǎo)從句.
I'll remember the time ______ we spent together in the country.
A.when B.at which C.that D.during which
正確答案：C (還可選which)
峰子回答,希望對朋友有幫助,什么情況會使用到during which？謝謝~during之后的which指代the time，所以during which=during the time，若用在句中相當(dāng)于時間狀語，這里需要的是賓語，不需要加介詞。若還是不明白，請繼續(xù)追問，謝謝！
