cease与halt的区别

首先，cease常做动词用，而halt作为名词用更常见。

当作为动词时，最主要的区别是，cease后面可以跟to

do/doing

sth（两者意思差不多，不像stop区别那么大）

而halt后面基本不跟to

do/doing

sth，其后一般只跟名词。用来表示停止的意思时，bring

sth

to

a

halt，call

a

halt

to

sth等短语反而更常见。

用 come to a stop造句

come

to

a

stop

中文释义：

停下来,停止

Emily Dickinson 的这首诗叫什么名字？表达了什么含义？

冬日的下午

余光中译

冬日的下午往往有一种

斜落下来的幽光，

压迫着我们，那重量如同

大教堂中的琴响。

它给我们以神圣的创伤；

我们找不到斑痕。

只有内心所引起的变化，

将它的意义蕴存。

没有人能够使它感悟；

它是绝望的烙印，

一种无比美妙的痛苦，

借大气传给我们。

当它来时，四野都倾听，

阴影全屏住呼吸；

当去时，远得像我们

遥望死亡的距离。

by

Emily

Dickinson

There’s

a

Certain

Slant

of

Light

[《冬日的下午〉或《有一种斜落下来的幽光》]

was

written

by

Emily

Dickinson

around

1861.

In

this

poem,

the

speaker

has

strong

feelings

about

a

beam

of

afternoon

light.

The

poem

is

possibly

about

death,

as

many

of

Dickinson

was

preoccupied

with

metaphysical

issues

in

her

poetry.

Dickinson

uses

rhyme,

simile

and

personification

to

produce

deep

meanings

in

the

poem.

In

Emily

Dickinson’s

lyrical

poem

“There’s

a

certain

slant

of

light”

she

describes

a

revelation

that

is

experienced

on

cold

“winter

afternoons.”

Further

she

goes

to

say

that

this

revelation

of

self

“oppresses,

like

the

Heft

of

Cathedral

Tunes”

and

causes

“Heavenly

Hurt”,

yet

does

not

scare

for

it

is

neither

exterior

nor

permanent.

This

only

leaves

it

to

be

an

internal

feeling,

and

according

to

Dickinson

that

is

where

all

the

“Meanings”

lie.

There’s

no

way

for

this

feeling

to

be

explained,

all

that

is

known

is

that

it

is

the

“Seal

Despair”,

and

an

“imperial

affliction”.

These

descriptions

have

a

rather

powerful

connotation

in

showing

the

oppressive

nature

of

his

sentiment.

There

is

an

official

mark

of

despair

and

an

imperial

affliction

which

is

above

and

beyond

the

norm.

The

severity

of

this

feeling

is

so

powerful

that

even

nature

seems

to

stop;

in

fact

the

whole

world

comes

to

a

halt.

But

when

it

is

over

it

seems

that

nothing

happened,

a

glimpse

of

death.

There

is

no

dramatic

situation

that

occurs

in

the

poem.

It

is

a

description

of

a

somber

feeling

that

comes

from

nowhere

and

leaves

without

a

trace.

The

poem

is

written

in

the

third

person,

referring

to

it,

the

feeling.

It

remains

in

that

point

of

view

throughout

the

entire

poem.

The

use

of

figurative

language

in

the

poem

allows

Emily

Dickenson

to

create

a

feeling

that

attaches

the

reader

to

the

poetry,

by

tying

it

to

an

experience

that

the

reader

might

have

had.
