近幾年各地中考試題中關(guān)于“時(shí)間點(diǎn)”和“時(shí)間段”這一類(lèi)型的考題較多，同學(xué)們比較容易混淆。下面對(duì)初中階段的“時(shí)間點(diǎn)”和“時(shí)間段”綜述如下：

一、“時(shí)間點(diǎn)”即“某時(shí)刻”，為時(shí)間坐標(biāo)軸上的一個(gè)點(diǎn)

1．“時(shí)間點(diǎn)”在一般過(guò)去時(shí)、一般現(xiàn)在時(shí)、一般將來(lái)時(shí)和各時(shí)態(tài)的進(jìn)行時(shí)中與“at”連用，意思是“在某個(gè)時(shí)刻”。對(duì)“at+時(shí)間點(diǎn)”劃線提問(wèn)，用“What time”或“When”。

考點(diǎn)舉例：

He often gets up at 5 in the morning．(對(duì)劃線部分提問(wèn))

_____ _____he often get up?(答案：When does)

2．“時(shí)間點(diǎn)”在現(xiàn)在完成時(shí)中，常與“since”或“ever since”連用。主句是現(xiàn)在完成時(shí)，since引導(dǎo)的時(shí)間狀語(yǔ)從句往往用過(guò)去時(shí)。

考點(diǎn)舉例：用動(dòng)詞的適當(dāng)形式填空：

She has lived here since she________(be)10 years old．(答案：was)

二、“時(shí)間段”即“一段時(shí)間”，為時(shí)間坐標(biāo)軸上的一段

1．“時(shí)間段”在現(xiàn)在完成時(shí)中與for連用，表示動(dòng)作持續(xù)的時(shí)間，相應(yīng)的謂語(yǔ)動(dòng)詞須是持續(xù)動(dòng)詞。對(duì)“for+時(shí)間段”劃線提問(wèn)，用“how long”。

考點(diǎn)舉例：

(1)I borrowed this book two days ago．(同義句轉(zhuǎn)化)

I_______ _______this booK______two days．(答案：have kept，for)

(2)My sister has been in America for 3 years.(對(duì)劃線部分提問(wèn))

_______ ______has your sister been in America?(答案：How long)

2．“時(shí)間段”在一般將來(lái)時(shí)中與“in”連用，表示動(dòng)作發(fā)生在該段時(shí)間之后，往往對(duì)應(yīng)短暫動(dòng)詞。對(duì)一般將來(lái)時(shí)中“in+時(shí)間段”劃線提問(wèn)，用“How soon”。

考點(diǎn)舉例：

(1)He will______in 5 months．

A．leave B．be away C．live D．be on (答案：A)

(2)They are going to finish the work in two days．(對(duì)劃線部分提問(wèn))

_______ _______are they going to finish the work?(答案：How soon)
