PATTERNS1
happen to do
[原句展示] I happened to be upstairs at dusk when the window was open
(P2)[点拨] 句中的 happen to do
为常用句式，意为“什么时候恰好发生什么事情”
如：She happened to be out when we called

It be the first (second / third
) time
(that)
[原句展示]
; it was the first time in a year and a half that I’d seen the night face to face
(P2)[点拨] It be the first (second / third
) time
(that)
是一个固定句型，意为“是第一（二 / 三……）次……”
该句型中的 that 从句用完成时态
如果主句谓语是一般现在时，后面从句用现在完成时态；如果主句是一般过去时，后面从句则用过去完成时态，该结构中的 that 可以省去
如：It is the first time I have been here
[比较] It is high time (time / about time) (that) + 主语 + did + 其它
该句型中 that 从句常用过去时，译为“是（正是）……的时候”
如：It is high time that we went home
