●句型梳理

1.By the time I got up，my brother had already gotten in the shower.

by the time意為“在……以前；到……的時(shí)候”，后面常接句子，用來(lái)限定時(shí)間，與before或when同義。如果從句用了一般過(guò)去時(shí)，主句一般常用過(guò)去完成時(shí)；如果主句用了一般將來(lái)時(shí)，從句常用一般現(xiàn)在時(shí)表示將來(lái)。例如：

By the time I got outside，the school bus had already gone.在我出門(mén)以前，校車(chē)已經(jīng)離開(kāi)了。

He will be a doctor by the time he is thirty.到三十歲時(shí)，他將會(huì)成為一名醫(yī)生。

【2015·龍東中考題】

A.rang B.has rung

C.had rung

【答案與解析】C by the time意為“在……以前；到……的時(shí)候”,如果其引導(dǎo)的時(shí)間狀語(yǔ)從句是一般過(guò)去時(shí),主句則用過(guò)去完成時(shí)。

2.I was about to go up when I decided to get a coffee first.

be about to do sth.意為“正要/馬上就要做某事”,可以表示將來(lái)的情況,但它表達(dá)的是最近的將來(lái)。例如：

The new term is about to begin.新學(xué)期就要開(kāi)始了。

【知識(shí)拓展】

be about to do sth.when...意為“正要做某事,這時(shí)……”,其中的when...意為“(突然)這時(shí)……”。例如：

I was about to go to bed when the phone rang.我正要上床睡覺(jué),這時(shí)電話響了。

They were about to leave when it started to snow.他們正要離開(kāi),這時(shí)突然開(kāi)始下起雪來(lái)。

We were about to start when it began to rain.我們剛要出發(fā)天就下起雨來(lái)。

【2016·德州中考題】

A.going B.to going

C.to go D.go

【答案與解析】C be about to do sth.when...意為“正要做某事，這時(shí)……”，about后面要用to do形式。

3.When I got to school,I realized that I had left my backpack at home.

“l(fā)eave sth.+地點(diǎn)”表示“把某物落在某地”，其中的“地點(diǎn)”多用介詞短語(yǔ)表示,要注意其中的動(dòng)詞leave不要換成forget。例如：

I left my passport in the hotel.我把我的護(hù)照落在旅館了。

Maybe you've left your key in the library.也許你把鑰匙落在圖書(shū)館了。

【真題鏈接】

—We can't enter the room.I can't find my key.

—Is it possible that you _____it at home?

【2017·南京中考題】

A.left B.fixed

C.managed D.designed

【答案與解析】A left(leave的過(guò)去式)意為“遺忘”；fix意為“修理”；manage意為“管理”；design意為“設(shè)計(jì)”。根據(jù)題干上句句意“我們不能進(jìn)入房間，我找不到我的鑰匙了?！辈⒔Y(jié)合所給選項(xiàng)可知，題干下句句意應(yīng)是“你會(huì)不會(huì)把它落在家里了？”。

4.As I was waiting in line with the other office workers,I heard a loud sound.

句中的as引導(dǎo)的是時(shí)間狀語(yǔ)從句。當(dāng)主句是一般過(guò)去時(shí)，as或just as引導(dǎo)的從句的謂語(yǔ)是過(guò)去進(jìn)行時(shí)，整個(gè)復(fù)合句表達(dá)的是“正當(dāng)/就在……的時(shí)候，另外一件事情發(fā)生了”。例如：

As we were walking across the fields,a hare jumped out the grass.正當(dāng)我們走路穿過(guò)田野時(shí)，一只野兔從草叢中跳了出來(lái)。

【真題鏈接】

A visitor arrived just as we _______out for the airport.

【2016·賀州中考題】

A.are setting B.were setting

C.will set D.have set

【答案與解析】B 句意：正當(dāng)我們要?jiǎng)由砣C(jī)場(chǎng)時(shí)，有位客人到了。根據(jù)句意和主句為一般過(guò)去時(shí)可知，設(shè)空處要用過(guò)去進(jìn)行時(shí)。

5.We're trying to save the earth.

try to do sth.意為“盡力去做某事”，其中的to是動(dòng)詞不定式符號(hào)，后面接動(dòng)詞原形，其否定形式為try not to do sth.。例如：

I will try to finish the work in a week.我將盡力在一周內(nèi)完成這項(xiàng)工作。

We try not to trouble him.我們盡量不打擾他。

【知識(shí)拓展】

try doing sth.表示“試著做某事”。例如：

Try doing it in another way.試著用另一種方法來(lái)做這件事。

【特別提醒】

manage to do sth.表示“設(shè)法完成(某件困難的事)”，包含經(jīng)過(guò)努力之后達(dá)到了目的。例如：

We managed to get to the airport on time.我們?cè)O(shè)法準(zhǔn)時(shí)趕到了機(jī)場(chǎng)。

【真題鏈接】

—I didn't hear you come in just now.

—That's good.I tried _______the baby up.

【2017·樂(lè)山中考題】

A.to wake B.not to wake

C.waking

【答案與解析】B 題干上句句意為“我剛才沒(méi)有聽(tīng)見(jiàn)你進(jìn)來(lái)”，根據(jù)題干下句中第一句的句意“那很好?！笨芍诙涞木湟鈶?yīng)是“我盡量不弄醒這個(gè)嬰兒”。try not to do sth.意為“盡量不做某事”。

6.I remember meeting all of you in Grade 7.

remember doing sth.意為“記得做過(guò)某事”，表示動(dòng)作已經(jīng)發(fā)生；remember to do sth.意為“記得要做某事”，表示動(dòng)作尚未發(fā)生。例如：

I remember telling you about it before.我記得以前和你談過(guò)這件事。

Please remember to phone me when you get there.到了那里請(qǐng)記住給我打個(gè)電話。

【真題鏈接】

—Remember _______it three or four times at least.

【2016·泰州中考題】

A.to understand;reading

B.understanding;reading

C.understanding;to read

D.to understand;to read

【答案與解析】C句意：——凌先生,我在理解這篇文章上有困難?！涀≈辽僖x三到四遍。have difficulty(in)doing sth.意為“做某事有困難”；remember to do sth.意為“記得要做某事”，表示某事還沒(méi)有做，remember doing sth.意為“記得做過(guò)某事”。結(jié)合句意及語(yǔ)境可知“至少要讀三到四遍”這個(gè)動(dòng)作還沒(méi)有發(fā)生。

7.But along with difficulties,there will also be many exciting things waiting for you.

There be sb./sth.doing sth.是固定句型，意為“有某人或某物正在做某事/某事正在發(fā)生”。be動(dòng)詞的數(shù)要與句型中主語(yǔ)的數(shù)保持一致。例如：

There are some little girls playing games under the tree.有一些小女孩正在樹(shù)下玩游戲。

There is a new machine working on the farm.在農(nóng)場(chǎng)有一臺(tái)新機(jī)器正在工作。

【答案與解析】B 根據(jù)題干下句句意“讓我們?nèi)ゼ尤胨麄儼伞笨芍?，題干上句句意應(yīng)是“有一些男孩正在那邊打籃球”，符合“There be sb.doing sth.”句型。
