it was not yet eight o'clock when he arrived home
如果改用 before,that,until,原句该怎么改?

-Did Jack come back early last night?
-Yes.It was not yet eight o'clock_____he arrived home.
A.before B.when C.that D.until
答：选B
解析：句意为：-Jack昨晚回来得很早吗?-是啊,他到家时还不到8点.
考生的思维定势有二：首先,认为是在考查强调句.同学们熟记了强调句型：It be+被强调部分+that/who+其余部分.而判断一个句子是否为强调句型,只需将其中的It is/was和who/that去掉,如果句子结构完整通顺,则是强调句型,否则就可能是其他语法形式.如果选C项,去掉It was和所填的that后,时间状语前缺少介词,句法错误,因此该句不是强调句型,而是状语从句.
其次,认为是在考查it…before…句型.It is+时间段+before句型的肯定式表示“过多久……才、就”；否定式表示“不久……才、就”.此题如用before罗辑不符,故答案选B.

it was not yet eight o'clock when he arrived home it is not yet eight o'clock when he arrived home.什么从句? it was not yet eight o'clock before he arrived home.求翻译外加bef 改错:It was not 8 o'clock until he arrived home . it was not yeat seven o clock---he got home James came back home early last night.It was not yet eight o it ________around eight o"clock when i drove back home It was eight o'clock when I ___ the station. 1：It was 6 o'clock -------he came home A.that B.what C.when The train arrived at______(exact)eight o'clock.It was neithe it was 6 when he arrived home改为疑问句英语翻译我完全读不懂啊.It was not yet eleven o'clock when a boat crosse
