it there be的用法

I.要點

1、it的用法

(1)用作人稱代詞,代替前文提到的無生命的事物,動植物、嬰兒及指示代詞this, that,如,

I have a new pen. It is beautiful.

The Browns have a new baby. It's cute.

(2)用來表示時間、天氣、距離等,如,

It's twelve o'clock now.

It's fine today.

(3)用作引導詞,代替由不定式,ing形式或從句表示的真正的主語或賓語,如,

It's no good telling him that.

It's necessary for you to do so.

(4)用在強調結構中,構成強調句式:It is/was +被強調部分+that/who/whom +句子其余部分,可強調除謂語以外的句子其他成分,如,

It was this morning that I saw him in the street.

It was I who saw him in the street this morning.

It was in the street that I saw him this morning.

It was him whom I saw in the street this morning.

2、there be句型

英語表示某時某處或某物時,常用there be句型,這是一種倒裝結構,如,

There are a lot of students playing on the ground.

There is going to be a test this afternoon.

當主語有兩個或兩個以上時,動詞be常和最近的那個主語取得一致,如,

There is a pen and three pencils in the pencil-box.

There isn't a desk, a bench and three chairs in the room.

There are lots of people like it, aren't there?

there be句型,謂語動詞除be之外,還可用其他表示存在,位置移動等意義的不及物動詞或詞組,如exist, stand, lie, enter, come, happen to be, appear to be等,如,

There stands a house at the foot of the hill.

there be句型表示"存在"而have表"有"、"擁有",所以there be中be不能換成have,但當have表示事物的特征時,可用"主語+have"結構替換there be 句型,如:

There are five doors in the house.

The house has five doors.

there be 的其它句型:

1、There must be a meeting in the office.

2、There have been great changes since 1979.

3、There being no bus, we had to walk home.

I例題

例1____ that he went to sleep.

A It was until midnight B That was until midnight

C It was not until midnight D That was not until midnight

解析:該題答案為C。強調until結構時,要將否定詞not移到until前。又如:He didn't leave until twelve 改為It was not until twelve that he left.

例2There are a lot of students ____ in the class room.

A talk B talking C talked D to talk

解析:該題正確答案為B。There be句型為倒裝句,可換為A lot of students are talking in the class room. 又如:There is a lot of noise heard out in the street.
