3.1 be動(dòng)詞的過(guò)去時(shí)
3.1.1 be動(dòng)詞過(guò)去時(shí)的構(gòu)成
肯定句：主語(yǔ) + be動(dòng)詞的過(guò)去式(was/were)...
否定句：主語(yǔ) + be動(dòng)詞的過(guò)去式(was/were) + not...
疑問(wèn)句：be動(dòng)詞的過(guò)去式(Was/Were) + 主語(yǔ)...?
疑問(wèn)代詞/疑問(wèn)副詞 + was/were + 主詞...?
3.1.2 be動(dòng)詞過(guò)去時(shí)的肯定句
句型：主語(yǔ) + was/were...
be動(dòng)詞過(guò)去時(shí)由“主語(yǔ) + be動(dòng)詞的過(guò)去式(was/were) + 表語(yǔ)”構(gòu)成：
I was here yesterday.昨天我在這里。
We were hungry.我們當(dāng)時(shí)餓了。
The concert was last night.音樂(lè)會(huì)在昨晚舉行。
The biggest problem was that we didn't have enough time.最大的問(wèn)題是我們當(dāng)時(shí)沒(méi)有足夠的`時(shí)間。
There were some students on the campus.校園里有一些學(xué)生。
比較be動(dòng)詞的現(xiàn)在式和過(guò)去式：
【注意】 there is/are句型的一般過(guò)去時(shí)為there was/were。
3.1.3 be動(dòng)詞過(guò)去時(shí)的否定句
句型：主語(yǔ) + was/were + not...
be動(dòng)詞過(guò)去時(shí)的否定句結(jié)構(gòu)是在be動(dòng)詞過(guò)去式was/were后面加上not。否定式的was not，were not大多使用縮寫形式wasn't(讀作/′w znt/)和weren't(讀作/w nt/)：
I was not here yesterday.昨天我不在這里。
He wasn't busy the other day.前幾天他不忙。
There weren't any students in the classroom.教室里一個(gè)學(xué)生也沒(méi)有。
3.1.4 be動(dòng)詞過(guò)去時(shí)的一般疑問(wèn)句
句型：Was/Were + 主語(yǔ)...?
回答方式：Yes，主語(yǔ) + was/were...
No，主語(yǔ) + wasn't/weren't...
be動(dòng)詞過(guò)去時(shí)的一般疑問(wèn)句結(jié)構(gòu)是將be動(dòng)詞過(guò)去式was/were置于主語(yǔ)之前(大寫was/were的第一個(gè)字母)，在句尾加問(wèn)號(hào);這種語(yǔ)序是主語(yǔ)和謂語(yǔ)倒裝語(yǔ)序：
Were you here yesterday? —Yes，I was.你昨天在這里嗎? ——是，我在。
Was there any water in the river then? —Yes，there was./No，there wasn't.那時(shí)那條河里有過(guò)水嗎? ——是的，有過(guò)。/不，沒(méi)有。
Were your parents pleased to hear about your new job? —Yes，they were./No，they weren't.你父母聽(tīng)說(shuō)你有了新工作后，他們高興嗎? ——是。/不是。
3.1.5 be動(dòng)詞過(guò)去時(shí)的特殊疑問(wèn)句
句型：疑問(wèn)代詞(主語(yǔ))/疑問(wèn)限定詞的名詞詞組(主語(yǔ)) + was/were...?
疑問(wèn)代詞/疑問(wèn)副詞 + was/were + 主語(yǔ)...?
就主語(yǔ)提問(wèn)時(shí)，將疑問(wèn)代詞或帶有疑問(wèn)限定詞的名詞詞組置于be動(dòng)詞過(guò)去式was/were之前(was/were的第一個(gè)字母無(wú)需大寫)，和一般疑問(wèn)句差不多，在句尾加問(wèn)號(hào);這種語(yǔ)序是陳述句語(yǔ)序。就表語(yǔ)提問(wèn)時(shí)，則以一個(gè)疑問(wèn)代詞或疑問(wèn)副詞開(kāi)頭，之后是“be動(dòng)詞過(guò)去式was/were + 主語(yǔ)”，在句尾加問(wèn)號(hào);這種語(yǔ)序是主語(yǔ)和謂語(yǔ)倒裝語(yǔ)序：
Who was here yesterday? —I was here yesterday.昨天誰(shuí)在這里? ——昨天我在這里。(就主語(yǔ)提問(wèn))
