in case用於什麼時態
in case有假使;以防;也許等意思，那麼你知道in case用於什麼時態嗎?下面是本站小編為你整理的in case的時態的相關資料，希望大家喜歡!
原則上說，若主句為現在時態，則從句也用現在時態;主句為過去時態，從句也用過去時態。如：
I always keep candles in the house in case there is a power cut. 我家裡常備有蠟燭，以防斷電。
I wrote down her address in case I forgot it. 我記下了她的住址，免得忘了。
He wasn’t going to use his car in case somebody recognized it. 他不打算用自己的汽車，因為怕有人認出他的車。
有時從句也可用“should+動詞原形”這樣的虛擬語氣(不管主句為現在時態還是過去時態)。如：
I don’t let him go out in this weather in case he should catch cold. 我不讓他這種天氣出去以防他會感冒。
I’ve bought a chicken in case your friend should stay to lunch. 我買了一隻雞，免得你的朋友萬一留下來吃午飯沒菜。
注意，當主句為將來時態時，從句謂語不能用將來時態，而要用一般現在時表示將來意義。如：
I’ll keep a seat for you in case you change your mind. 我給你留一個座位，以防你會改變主意。
