初三英語上冊(cè)知識(shí)點(diǎn)歸納

1.介詞的功能

介詞是一種虛詞，用來表示名詞或相當(dāng)于名詞的其它詞語句中其它詞的關(guān)系，不能單獨(dú)使用。介詞可與名詞或相當(dāng)于名詞的其它詞構(gòu)成介詞短語。介詞短語可在句中作定語，狀語，表語和賓語補(bǔ)足語。例如：

The boy over there is John’s brother. (定語)

The girl will be back in two hours. (狀語)

Our English teacher is from Australia. (表語)

Help yourself to some fish. (賓語補(bǔ)足語)

2.常用介詞的用法辨析

(1)表時(shí)間的介詞

at, in on

表示時(shí)間點(diǎn)用at。例如：at six o’clock, at noon, at midnight。表示在某個(gè)世紀(jì)，某年，某月，某個(gè)季節(jié)以及早晨，上午，下午，晚上時(shí)，用in。例如：in the ninettenth century, in 2022, in may, in winter, in the morning, in the afternoon等。表示具體的某一天和某一天的上午，下午，晚上時(shí)，用on。例如：on Monday, on July 1st, on Sunday morning等。

since, after

由since和after 引導(dǎo)的詞組都可表示從過去某一點(diǎn)開始的時(shí)段，但since詞組表示的時(shí)段一直延續(xù)到說話的時(shí)刻，因而往往要與現(xiàn)在完成時(shí)連用。而after詞組所表示的時(shí)段純系過去，因而要與一般過去時(shí)連用。例如：

I haven’t heard from him since last summer.

After five days the boy came back.

in, after

in與將來時(shí)態(tài)連用時(shí)，表示“過多長時(shí)間以后”的意思，后面跟表示一段時(shí)間的詞語。After與將來時(shí)態(tài)連用時(shí)，后面只能跟表示時(shí)間點(diǎn)的詞語。After與過去時(shí)態(tài)連用時(shí)，后面才能跟表示一段時(shí)間的詞語。例如：

He will be back in two months.

He will arrive after four o’clock.

He returned after a month.

(2)表示地點(diǎn)的介詞

at, in, on

at一般指小地方;in一般指大地方或某個(gè)范圍之內(nèi);on往往表示“在某個(gè)物體的表面”。例如：

He arrived in Shanghai yesterday.

They arrived at a small village before dark.

There is a big hole in the wall.

The teacher put up a picture on the wall.

over, above, on

over, on和above都可表示“在……上面”，但具體含義不同。Over表示位置高于某物，在某物的正上方，其反義詞是under。 above也表示位置高于某物，但不一定在正上方，其反義詞是below。On指兩個(gè)物體表面接觸，一個(gè)在另一的上面。例如：

There is a bridge over the river.

We flew above the clouds.

They put some flowers on the teacher’s desk.

across, through

across和through均可表示“從這一邊到另一邊”，但用法不同。Across的含義與on有關(guān)，表示動(dòng)作在某一物體的表面進(jìn)行。Throgh的含義與in有關(guān)，表示動(dòng)作是在三維空間進(jìn)行。例如：

The dog ran across the grass.

The boy swam across the river.

They walked through the forest.

I pushed through the crowds.

in front of, in the front of

in front of 表示“在某人或某物的前面”，在某個(gè)范圍以外;in the front of 表示“在……的前部”，在某個(gè)范圍以內(nèi)。例如：

There are some tall trees in front of the building.

The teacher is sitting in the front of the classroom.

3.介詞的固定搭配

介詞往往同其他詞類形成了固定搭配關(guān)系。記住這種固定搭配關(guān)系，才能正確使用介詞。

(1)介詞與動(dòng)詞的搭配

listen to , laugh at, get to, look for wait for, hear from, turn on, turn off, worry about, think of, look after, spend…on…， 等。

(2)介詞與名詞的搭配

on time, in time, by bus, on foot, with pleasure, on one’s way to, in trouble, at breakfast, at the end of, in the end等。

(3)介詞與形容詞的搭配

be late for, be afraid of, be good at, be interested in, be angry with, be full of, be sorry for等。

感官動(dòng)詞后既可跟不帶to的不定式作賓補(bǔ)，也可跟v-ing作賓補(bǔ)，前者表示動(dòng)作的全部過程已結(jié)束;后者表示動(dòng)作正在進(jìn)行。

go on doing 繼續(xù)做原來在做的事

2. 不定式作賓語時(shí)，如帶有賓語補(bǔ)足語，則要把不定式放到后面，用it作形式賓語，構(gòu)成“主語+動(dòng)詞+it+賓補(bǔ)(形容詞、名詞)+不定式”結(jié)構(gòu)。

如：He found it very difficult to get to sleep.他發(fā)現(xiàn)很難入睡。
