人教版八年級下冊Unit 5 What were you doing when the rainstorm came?過去進行時要點總結

資源簡介

過去進行時
一、概念
表示過去某個時間點或時間段正在進行的動作。
二、構成
(一)肯定句
主語 + was/were + 動詞的現在分詞 + 其他。
I was reading a book at 8 o'clock last night.(昨晚八點我正在讀書。)
She was singing in the classroom when I came in.(我進來的時候她正在教室里唱歌。)
They were playing basketball from 3 to 5 yesterday afternoon.(昨天下午三點到五點他們正在打籃球。)
(二)否定句
主語 + was/were + not + 動詞的現在分詞 + 其他。
I was not reading a book at 8 o'clock last night.(昨晚八點我沒在讀書。)
She was not singing in the classroom when I came in.(我進來的時候她沒在教室里唱歌。)
They were not playing basketball from 3 to 5 yesterday afternoon.(昨天下午三點到五點他們沒在打籃球。)
(三)一般疑問句
Was/Were + 主語 + 動詞的現在分詞 + 其他?
Were you reading a book at 8 o'clock last night (昨晚八點你正在讀書嗎?)
Was she singing in the classroom when I came in (我進來的時候她正在教室里唱歌嗎?)
Were they playing basketball from 3 to 5 yesterday afternoon (昨天下午三點到五點他們正在打籃球嗎?)
(四)特殊疑問句
特殊疑問詞 + was/were + 主語 + 動詞的現在分詞 + 其他?
What were you doing at 8 o'clock last night (昨晚八點你正在做什么?)
Where was she singing when I came in (我進來的時候她正在哪里唱歌?)
Who were they playing basketball with from 3 to 5 yesterday afternoon (昨天下午三點到五點他們正在和誰打籃球?)
三、動詞現在分詞的變化規則(同現在進行時)
(一)一般情況下,直接在動詞原形后加 -ing。
play - playing
read - reading
watch - watching
(二)以不發音的字母 e 結尾的動詞,去掉 e,再加 -ing。
come - coming
make - making
write - writing
(三)以重讀閉音節結尾,末尾只有一個輔音字母的動詞,先雙寫這個輔音字母,再加 -ing。
run - running
stop - stopping
swim - swimming
(四)以 ie 結尾的動詞,把 ie 變為 y,再加 -ing。
lie - lying
die - dying
tie - tying
四、常見標志詞
at 8 o'clock last night(昨晚八點)、when I came in(當我進來的時候)、from 3 to 5 yesterday afternoon(昨天下午三點到五點)等表示過去具體時間點或時間段的短語。
五、用法
(一)過去某個時間點正在進行的動作
常與表示過去的具體時間點連用,如 at 9:00 last Sunday(上周日九點)、at noon yesterday(昨天中午)等。
My mother was cooking dinner at 6 o'clock yesterday evening.(昨天晚上六點我媽媽正在做晚飯。)
(二)過去時間段內持續進行的動作
常與表示過去一段時間的短語連用,如 from 8 to 10 this morning(今天上午八點到十點)、the whole morning yesterday(昨天整個上午)等。
They were cleaning the classroom the whole afternoon yesterday.(昨天整個下午他們都在打掃教室。)
(三)用于 when 和 while 引導的時間狀語從句
when 引導的從句,動詞既可以是短暫性動詞(用一般過去時),也可以是延續性動詞(用過去進行時)。從句動作發生時,主句動作正在進行。
When the teacher came in, we were talking.(老師進來的時候,我們正在講話。)
while 引導的從句,動詞必須是延續性動詞(用過去進行時),強調主句和從句的動作同時進行。
While I was reading, my sister was watching TV.(我讀書的時候,我妹妹正在看電視。)
六、練習題
(一)用所給動詞的適當形式填空
I ______ (watch) TV at 7 o'clock last night.
She ______ (play) the piano when her mother came back.
They ______ (have) a party from 8 to 10 last night.
(二)將下列句子改為否定句
He was doing his homework at 9 o'clock last night.
They were dancing at the party when I arrived.
(三)對劃線部分提問
She was reading a storybook at 8 o'clock yesterday evening.(對 reading a storybook 提問)
They were playing football on the playground at 3 o'clock yesterday afternoon.(對 on the playground 提問)
