Answer 1

【小題1】heard
【小題2】until
【小題3】arguing
【小題4】strange
【小題5】chance

解析【小題1】本句的從句為一般過(guò)去時(shí)，故主語(yǔ)也應(yīng)該用過(guò)去式，故本題空格處填聽(tīng)見(jiàn)的過(guò)去式heard。
【小題2】本題的含義為疲憊的孩子們直到晚上7點(diǎn)鐘才到家，not……until表示直到……才的含義，故本句空格處填until。
【小題3】while后引導(dǎo)的從句為過(guò)去進(jìn)行時(shí)，結(jié)構(gòu)為was+現(xiàn)在分詞，故本句空格處填爭(zhēng)吵的現(xiàn)在分詞arguing。
【小題4】be動(dòng)詞后跟形容詞，在感嘆句中，how后跟形容詞，故本句空格處填奇怪的形容詞strange。
【小題5】本句的含義為這是許多人沒(méi)有的極好的機(jī)會(huì)，冠詞a后跟名詞，故本題空格處填機(jī)會(huì)的名詞形式chance。
