instead和however区别

这两个词都是副词，但意思不同。instead表示与…相反，替代…可单独使用，用逗号与句子其余部分相隔，后面加介词of后可接宾语。而however意思是但是，表示转折，也要用逗号与其余部位相隔。

instead和however区别

instead和however都表示转折，但是用法有所不同。however表示让步，意为“无论如何”“不管怎样”，用来修饰形容词或副词，表示转折，尤其用于谈及一个既成事实时，其意为“可是”“仍然”等。

而instead则更侧重于“取而代之”这层意思，表示代替。例如，“I don't like coffee, but I like tea.”中的but表示相反的情况，而“Instead of coffee, I like tea.”中的instead则表示代替。

1、instead

作副词意思是代替；反而，但它的意思更侧重于“取而代之”这层意思。所以往往翻译成“相反地”。

2、however

作副词意思有然而；无论如何；不管多么。作连词意思是不管怎样，不过，表示一种转折，说明后面陈述的内容与前面的内容相反。

“反而”与“不过，但是”的区别，就是“instead”和“however”的区别，eg:

我很累，但是我能坚持，（这里就用：I feel a bit tired. However, I can hold on.）

这消息非但没有令她不安，反而产生了一种奇怪的镇定效果。

这里就用（Instead of disturbing her, the news had a strangely calming effect.）

看两个例句：

I will go there though she is unhappy.However,her mother will go there instead.

It was raining hard. However, we went out to look for the boy.

however：主要强调通过增加某个令人吃惊或者进行比较的情况/评论对前面动作加以说明和修正。（强调对比让步关系）

instead 主要强调做出另外一个不同之前的一个选择。（强调取舍关系）

however近义词辨析

but，however，still，yet，nevertheless，while，whereas这些连词或副词均含“但是，可是，然而，而”之意。

but口语常用词，语气较强，泛指与前述情况相反。

however表转折关系，语气稍弱于but，连接性也弱一些，因而常作插入语。

still语气强，多用于肯定句或疑问句。

指尽管作出让步，采取措施或表示反对，但情况仍然如故，无所改变。

yet常用于否定句，语气比still稍强。

指不管作出多大努力或让步，仍达不到预期的结果。

nevertheless指尽管作出完全让步，也不会发生任何影响。

while表对比，一般可与whereas换用，但程度弱一些。

whereas表对比，一般可与while互换。

however的用法总结

一、however 可以置于句首，以逗号隔开，译为“然而、可是、仍然”等，例如：

He was feeling very ill. However, he went to school.

他感到很不舒服。但他仍然去上学了。

She is the best student in school. However, she doesn’t do homeworks on time.

她是学校里最好的学生。可是她没有按时做家庭作业。

二、however 还可以出现在主语或 be 动词之后，或实义动词之前，前后以逗号隔开，例如：

Many problems, however, escape detection.

然而许多问题却未被察觉。

We had a small drop in sales last month. We are, however, still above the plan.

上个月我们的销售额略有下降。然而，我们仍高于计划。

They do, however, share a mutual interest in design.

不过他们确实都对设计感兴趣。

三、当 however 用于连接两个独立的句子，应在 however 前面加分号“；”，或另起新句，例如：

I'd like to go with you; however, my hands are full.

我很想和你一块儿去，可是我忙不过来。

解析：此句等于 I'd like to go with you. However, my hands are full.

It’s raining hard; however, I think we should go out.

雨下得很大，但我想我们还得出去。

解析：此句等于 It’s raining hard. However, I think we should go out.

四、在非正式写作中，however 还可以放在句尾，前面以逗号隔开，例如：

Laptop sales surpassed tablet sales in the last year. Mobile phones still remain the highest selling gadget, however.

去年，笔记本电脑的销量超过了平板电脑。然而，手机仍然是最畅销的电子产品。

五、虽然 however 可以以特殊的方式连接两个独立的句子，但不能被当作连词用，例如：

I was offered a promotion at the end of March, however I turned it down. I didn’t want the extra responsibility for a small pay increase.

三月底有人给我升职，但我拒绝了。我不想因为一点点加薪而承担额外的责任。

解析：以上不能用 however，此时只能用 but，正确的是：

I was offered a promotion at the end of March, but I turned it down. I didn’t want the extra responsibility for a small pay increase.

三月底有人给我升职，但我拒绝了。我不想因为一点点加薪而承担额外的责任。

We invited 100 customers to the presentation however only about 50 came.

我们邀请了100位顾客来参加演示，但只有大约50位顾客来了。

解析：以上不能用 however，此时只能用 but 或 however 特殊的连接独立句子的方式。

六、however 与副词或形容词连用，译为“无论到什么程度，不管多么”，例如：

1. however good/well/bad/badly/hard 等

3. however long something takes

不管你怎么看，这是一个非常令人担忧的消息。
