英语语法中的 关系从句 和 从属从句 有什么区别？

1. 英语中的关系词，指的就是定语从句中的连接主句和从句的中间的那个代词或副词，具体相关的定义如下：

复合句中，用一个句子作定语修饰某一名词或代词，有时也可以用来修饰一个名词性短语，也可以修饰一个句子，这样的从句叫定语从句(attributive clause)。定语从句修饰的词叫做先行词或中心词(antecedent)；连接定语从句的词叫关系词(relative)。先行词与关系词之间实质上是互等关系。也就是说，关系词的作用就是将先行词所表达的意义代到从句中来起作用。定语从句必须放在先行词/中心词之后，而引导定语从句的词有关系代词：as, that, which, who, whom, whose(特殊句式中but, than也作关系代词)和关系副词：when,where, why等。

This is the house where/in which we lived last year.这就是我们去年住的房子。

I still remember the day when/on which I first came to Beijing.我仍记得第一次去北京的那一天。

His parents wouldn't let him marry anyone whose family was poor.他父母不让他和家庭困难的人结婚。

Finally, the thief handed everything (that) he had stolen to thepolice.最后，那个小偷向警察交出他偷的所有的东西。

In the dark street, there wasn't a single person to whom she could turnfor help.在那个黑暗的街道上，没有她可以求助的人。

In 1519 another traveler who went to America from Europe discoveredthe tomato.1519年另一位从欧洲去美洲的旅行家发现了西红柿。

2. 从属从句的概念就比较广了，名词性从句的主语从句、表语从句、宾语从句、同位语从句；起副词作用的状语从句；起定语作用的定语从句。这些都是从属从句。

引导主语从句的关联词有三类：

(1) 从属连词that，放于句首，不可省略，用形式主语it的主语从句中口语中可以省略that。

That they were in truth sisters was clearfrom the facial resemblance between them.很明显，她们确是亲姐妹，她们的脸型很相似。

→It was clear from the facial resemblance between them (that) theywere in truth sisters.

(2) 从属连词whether(不可以用if)表示“是否”。

Whether he'll come here isn't clear.他是否会来这里还不清楚。

(3) 连接代词what, whatever, which, whichever, who, whom, whoever, whose等。

(4) 连接副词how,when, where, why等。

Whoever comes is welcome.不论谁来都欢迎。

What she did is not yet known.她干了什么尚不清楚。

How this happened is not clear to anyone.这事怎样发生的，谁也不清楚。

Wherever you are is my home - my only home.你所在的任何地方就是我的家—我唯一的家。

3. 状语从句根据它们的含义分为时间、地点、原因、目的、结果、方式、让步、条件、比较(也叫程度)等九种。状语从句连词有：

① 时间(time): after, as,as soon as, before, every(each) time, hardly(scarcely)…when,immediately, no sooner…than, once, since, the day, the minute, the moment, the second,till, until, when, whenever等。

② 地点(place):everywhere, where, wherever等。

③条件(condition): as/so long as, if, if only, in case, on condition that,only if, providing/provided that, suppose/supposing that, unless等。

④原因(cause): as, because, considering that, in that, in view of the factthat(鉴于), now that, seeing that, since等。

⑤让步(concession): though, although, as, despite the fact that, evenif(though), for all that, granting/granted, however, in spite of the fact that,no matter + wh-, whatever, wherever, whether…or, while, whoever等。

⑥比较/程度(compare/degree): as…as, not so…as, not the same as, than等。

⑦方式(manner): as, as if(though), the way等。

⑧目的(purpose): for fear that, in order that, in case, lest, so that,that等。

⑨结果(result): but that, so that, so…that, such…that等。

都是Mint薄荷，是2种口味有些微差别的用在食品里的薄荷。

Peppermint里含有薄荷醇，会影响我们嘴里的神经，让大脑感觉到嘴里比实际更强的清凉感。这也是吃辛辣食品时喝薄荷饮料会很搭的原因。

这两种薄荷在食谱里也常可以交换交替使用，完全看个人喜好。

下面是详细解释，来源于：The Kitchn.com

There are two main kinds of mint that we use for culinary purposes: spearmint and peppermint. Both have squared-off stems with bright green, spear-shaped leaves. Peppermint has a sharper flavor and more intense aroma, while spearmint tends to be more delicate and sweet. They grow everywhere and in a wide variety of climates, which is why the herb is found in so many world cuisines.

Peppermint also contains the chemical menthol. This chemical affects the nerve endings in our mouths and makes our brains think the mouth is cooler than it really is. This is why minty beverages are great to sip while eating spicy foods.

Spearmint and peppermint can be used interchangeably, in sweet and savory recipes, alike. It pairs well in everything from savory dishes with roasted meats and rich sauces, to lighter dishes, like simple vegetable side dishes, beverages like yogurt lassis and tea, and desserts.
