翻译 _______(我刚刚到家)than the telephone rang

No sooner had I got home than the telephone rang.
关键是than.no sooner...than是固定搭配的句型,类似的有hardly...when.但是它们之间的搭配不能互用.所以空缺的部分应该是用来no sooner完成.而如果给出的是when的话,则应该这样来回答--Hardly had I got home when the telephone rang.

No sooner had he got home than the telephone rang.

i just got home no sooner than the telephone rang

No sooner had I got home...

as soon as I got home

Hardly had i reached home
