1. if和asif在意思用法上有什么区别
as if的用法如下
1. 在look, seem 等系动词后引导表语从句。
如: She looks as if she were ten years younger. 她看起来好像年轻了十岁。 It seems as if our team is going to win. 看来我们队要胜了。
2. 引导方式状语从句。
如: She loves the boy as if she were his mother. 她爱这男孩,就好像她是他的母亲一样。 The child talked to us as if he were a grown up. 那孩子跟我们谈起话来,像个成年人似的
3.as if用于虚拟语气。
as if 从句用虚拟语气的情况。 当说话人认为句子所述的是不真实的或极少有可能发生或存在的情况时。从句虚拟语气动词时态的形式如下: (1)如果从句表示与现在事实相反,谓语动词用一般过去时。如: You look as if you didn’ t care. 你看上去好像并不在乎。 He talks as if he knew where she was. 他说话的样子,好像他知道她在哪里似的。 (2)从句表示与过去事实相反,谓语动词用“had+过去分词”。如: He talks about Rome as if he had been there before. 他说起罗马来好像他以前去过罗马似的。 The girl listened as if she had been turned to stone. 那女孩倾听着,一动也不动,像已经变成了石头似的。 (3)从句表示与将来事实相反,谓语动词用“would/could/might+动词原形”。如: He opened his mouth as if he would say something. 他张开嘴好像要说什么。 It looks as if it might snow. 看来好像要下雪了
2. as if 后面的语法是什么 怎么用的
as
if和as
though两者的意义和用法相同,引导的从句中的时态取决于说话者对所谈内容的态度。引出的状语从句谓语用虚拟语气,表示与事实相反;用陈述语气,表示所说情况是事实或实现的可能性较大。
汉译常作"仿佛……似的","好像……似的"。
这两个连词经常用在be,act,appear,behave,fell,look,seem,smell,sound,taste及其他描写行为举止的动词之后,引导一个方式从句。
They
completely
ignore
these
facts
as
if
(as
though)
they
never
existed.
他们完全忽略了这些事实,就仿佛它不存在似的。(与事实相反,谓语用虚拟语气。)
He
looks
as
if
(as
though)

had
been
hit
by
lightning.

It
looks
as
if
the
weather
may
pick
up
very
soon.

(2)asif证券扩展阅读
说明:as
if
/
as
though也可以引导一个分词短语、不定式短语、形容词或介词短语,例如:
He
stared
at
me
as
if
seeing
me
for
the
first
time.
他目不转睛地看着我,就像第一次看见我似的。
He
cleared
his

say
something.

waves
dashed
on
the
rocks
as
if
in

3. as和asif作为好像的意思时有什么区别
比如说这两个句子:
He
looked
just
as
he
had
looked
ten
years
before.
这个句子是陈述语气
他看上去就像他10年前的样子.(说明他像10年前一样年轻)
She
looked
as
if
she
were
ten
years
younger.
这个句子是虚拟语气
他看上去,好象他年轻了10岁,实际上不是这样的.
4. as if语法
as
if的用法有两种情形:第一,在真实条件状语从句(Adverbial
Clause
of
Condition)中,as
if
不用虚拟语气,时态随主句变化而变化,表示事情可能存在
或者发生;第二,在非真实条件状语从句中,前面是LOOK
SEEM等词连用
as
if后面用虚拟语气,1、对现在的虚拟用过去时
注意
无论什么形式的BE动词
一律用WERE;2、对过去的虚拟用had
done形式;3、对将来的虚拟用would+do
或were
+to
do\gong
to
do
这是我自己总结的
虽然不太完全
但是应付一些基本的语法还是足够了……
5. as if 的用法
as
if
从句用虚拟语气的情况。
当说话人认为句子所述的是不真实的或极少有可能发生或存在的情况时。从句虚拟语气动词时态的形式如下:

where

8. asif和asthough有什么区别,什么时候用前者什么时候用后者
as if和as though的区别为意思不同、用法不同、侧重点不同,使用区别如下:
一、意思不同
1.as if意思:好像…一样,仿佛,似乎,(表示判断)好像,似乎,(表示类比)好像,仿佛,似乎。
2.as though意思:好像。
二、用法不同
1.as if用法:if作为从属连词,可引导条件状语从句、让步状语从句和名词从句。if引导条件状语从句,从句可为真实条件从句,也可为虚拟条件从句。如为真实条件从句,谓语用陈述语气,表示可能性很大,通常用一般现在时代替一般将来时,如果if从句中用will,表示意愿。
2.as though用法:though引导让步状语从句时表示一种假设的情况或含有推测的意味,从句的谓语动词可用陈述式,也可用虚拟式,有时为了强调让步的意义,可采用倒装语序。在用though连接的从句中,谓语是be,而从句的主语与主句的主语相同时,从句的主语与be可同时省略。
三、侧重点不同
1.as if侧重点:侧重于口语形式,简练。
2.as though侧重点:侧重于书面语形式,正式。
9. asif的用法
as if 的用法 as if 好像,好似 She spoke to me as if she knew me. 她和我说话的神情,好像她早就认识我似的。 (= as though)as if 的用法 一、as if 从句的作用 1. 在look, seem 等系动词后引导表语从句。如: She looks as if she were ten years younger. 她看起来好像年轻了十岁。 It seems as if our team is going to win. 看来我们队要胜了。 2. 引导方式状语从句。如: She loves the boy as if she were his mother. 她爱这男孩,就好像她是他的母亲一样。 The child talked to us as if he were a grown?up. 那孩子跟我们谈起话来,像个成年人似的。 二、as if 还可用于省略句中 如果as if 引导的从句是“主语+系动词”结构,可省略主语和系动词,这样as if 后就只剩下名词、不定式、形容词(短语)、介词短语或分词。如: He acts as if (he was) a fool. 他做事像个傻子。 Tom raised his hands as if (he was going) to say something. 汤姆举起手好像要说什么。 She left the room hurriedly as if (she was)angry. 她匆忙离开房间好像生气的样子。 三、as if 从句的语气及时态 1. as if 从句用陈述语气的情况。 当说话者认为句子所述的是真实的或极有可能发生或存在的事实时。如: It sounds as if it is raining. 听起来像是在下雨。 He talks as if he is drunk. 从他谈话的样子来看他是醉了。 2. as if 从句用虚拟语气的情况。 当说话人认为句子所述的是不真实的或极少有可能发生或存在的情况时。从句虚拟语气动词时态的形式如下: (1)如果从句表示与现在事实相反,谓语动词用一般过去时。如: You look as if you didn’ t care. 你看上去好像并不在乎。 He talks as if he knew where she was. 他说话的样子,好像他知道她在哪里似的。 (2)从句表示与过去事实相反,谓语动词用“had+过去分词”。如: He talks about Rome as if he had been there before. 他说起罗马来好像他以前去过罗马似的。 The girl listened as if she had been turned to stone. 那女孩倾听着,一动也不动,像已经变成了石头似的。 (3)从句表示与将来事实相反,谓语动词用“would/could/might+动词原形”。如: He opened his mouth as if he would say something. 他张开嘴好像要说什么。 It looks as if it might snow. 看来好像要下雪了。
