高中英语知识点大全(19):be filled with 、be full of的用法
1、be filled with = be full of
be filled with = be full of 充满,装满 如:
The bottle is filled with water .瓶子里装满了水。
注意:Filled with courage , he went into the cave .此处filled 表示“充满了的”指处于一种状态。
比较:be crowded with 挤满的,与be filled with 有所不同。如:
The room is crowded with guests.房间里挤满了客人。
此外,fill作为动词可用其主动形式,亦可构成另外短语。如:
Fill the bottle with sand .把瓶子装满沙子。
Fill in the blanks .填空。
be full of?→be filled with?充满?
①The classroom was full of students.教室里挤满了学生。
②Her eyes were full of tears.她眼泪汪汪的。
2、be likely to
be likely to 易于??;有可能的. 后跟动词不定式,往往用在一时的情形。
I shall be likely to catch cold if I go out tonight without my overcoat.如果今晚不穿大衣出去,我会感冒的。
Is that magazine likely to interest you? 那本杂志对你有吸引力吗?
3、be of?结构小结
1
(1)be of + 表示年龄(age)、大小(size)、颜色(color)、重量(weight)、高度(height)、价格(price)、意见(opinion)、形状(shape)、种类(kind)和方法(way)等名词,说明主语的特征,of表示“具有”之意,有时可省去。例如:
They are both of middle height.他俩都是中等个儿。
When I was of your age, I was a teacher.当我是你这个年龄时,我当老师了。 These flowers are of different colors.这些花朵颜色不同。
Tom is of a different way of thinking.汤姆的思维方式与别人不同。
注意:此结构中,如果of后面的名词前有不定冠词a/an,则a/an=the same.例如: The two boys are of an/the same age.这两个男孩同龄。
These bottles are of a/the same size.这些瓶子大小一样。
(2)be of + 物质名词,表示主语是由某材料制成或某成分构成,相当于be made of, be built of或be made up of等。例如:
The necklace is(made)of glass.这项链是玻璃制的。
The bridge is (built)of stone.这桥是由石头构筑的。
Our class is (made up)of over 50 students. 我班有50多个学生。
(3)be of + 抽象名词(如value, importance,use, help等),of表示“具有、具备”等意思,of不能省,这一结构相当于be+该抽象名词相应的形容词。例如:
They are of great help/ very helpful to learners of English.他们对英语学习者来说是很有帮助的。
In fact, sports and games can be of great value/very valuable.事实上体育运动是很有价值的。
The book is of no use/useless to us.这书对我们无用。
2
It is of great importance/very important to study English.学习英语很重要。
因此,根据上述(1),(2)点可以看出,课文句中第一个be of 结构表示“具有”,第二个be of(承前省去be)表示“由??制成的”。全句汉语意思为:“硬币的大小、重量、形状可能各不相同,并由不同的金属制成。”

第二篇:高中英语 知识点大全29 but的用法
高中英语知识点大全(29):but的用法
1、broadcast
broadcast vt.;vi.广播;播放。过去式和过去分词均为broadcast。
①The BBC broadcasts every day.BBC每天都广播。
②The news was broadcast on the radio.这个消息是收音机里播送的。
2、but
but prep. 除?之外。与except同义,除了的部分与其他部分不在一个范围内,不具有一致性。except适用场合较多,but 主要用于带有nothing/nobody/no one/all 等不定代词的句子。
①No one except/but you was late.除你之外没有迟到。(你迟到了)
②We all went to see a film yesterday evening except/but you.除你之外作天晚上我们都去看电影了。(你没去)
③That window is open except in winter .除冬天外那窗户一直开着。(冬天不开) 另外,but后可接不不定式。如果句子前面有实义动词do及其变化形式时,不定式不带to; 否则不定式带to .
①I did nothing yesterday evening but watch TV.昨天晚上除看电视外我什么也没干。 ②He had no choice but to leave.他只得离开。
注意:besides 也是介词,意为“除??之外(还有)”。除了的部分和其他部分在同一个范围内,具有一致性。
①We all went to see a film yesterday evening besides you.除你之外昨天晚上我们也都去看电影了。(你和我们都去了)
1
②Who is going there with Tom besides you? 除你之外还有谁和汤姆一起去?
3、but for
该短语介词意为“要不是??”,后接名词(=without + n.),but for?短语相当于一个虚拟条件句,因此,句中谓语动词用虚拟语气。如:
The boy would have drowned but for your help.
如果接的是句子,but for要换用成but that?如:
He would have helped us but that he was short of money at the time.(= if it had not been the fact that he was?)
