however的用法

Question

如题所述

Answer 1

这里的However是插入语，表示强调。that 是作Note 的宾语从句。
不管怎样，要注意的是遥感术还包括。。。。

附上however 的用法，希望对你有帮助。

不管however以何种形式出现，它都不外乎以下两种用法。
1. 用作副词
(1) 表示让步：意为“无论如何”“不管怎样”，用来修饰形容词或副词，
其词序为：however+形容词或副词+主语+谓语。这样用的however其实具有连词的功能，用以引导让步状语从句。如：
however much he eats, he never gets fat. 不管他吃多少，他永远吃不胖。
用于此用法时，请注意以下几点：
①此用法属however所有用法中最重要的考点，同学们务请引起高度重视。
②这样用的 however 与 no matter how 大致同义。如：
People always want more, however [no matter how] rich they are. 人总是富了还想再富。
however [No matter how] hard I worked, she was never satisfied. 无论我多么努力地工作，她从来没满意过。
③有时从句谓语可用情态动词。如：
Don’t laugh, however funny it may be. 无论多么有趣也不要笑。
I’ll try to finish it in time, however hard it may be. 无论多么难，我也要按时完成。
④“however＋形容词或副词＋主语＋谓语”有时可以有所省略。如：
I refuse, however favorable the conditions. 不管条件如何有利，我都不干。(conditions后省去了are)
I’d rather have a room of my own, however small (it is), than share a room. 无论房间多么小，我宁愿一个人住一间，而不愿意与别人合住一个房间。
A grammar rule, however true (it is), is useless unless it can be understood. 一条语法规则，不管如何正确，除非能懂，否则毫无用处。

(2) 表示转折：尤其用于谈及一个既成事实时，表示转折，其意为“可是”“仍然”等。可放在句首、句中或句末，通常用逗号与句子其他成分隔开。如：
My father, however, did not agree. 但是，我父亲不同意。
My room is small; however, it’s comfortable. 我的房间很小，但却很舒服。
He said that it was so; he was mistaken, however. 他说情况如此，可是他错了。
注：however不能像 but(但是)那样直接连接两个句子(注意正句中的标点符号)。如：
我们都已尽了最大的努力，不过我们还是输了。.
正：We all tried our best, but we lost the game.
正：We all tried our best; however, we lost the game.
正：We all tried our best. however, we lost the game.
(3) 表示惊奇或强调：相当于how ever的用法，其意为“究竟怎样，到底以什么方式”。如：
however did you get here without a car? 没有汽车你究竟是怎样来的呢?

conj. 然而；可是

Unity, however, also has its risks.

Answer 3

1、however可以做副词，含义为“但是，可是，不过”。多插在句中，有时放在句首或句尾。
例如：However，they did not seem to have much effect.
不过，他们似乎没有起太大的作用。
He said that it was so; he was mistaken，however.
他说事情就是这样；然而，他错了。
2、however还可以做连词，含义为“不管……如何，多么”，引导让步状语从句。从句的语序为：however+adj./adv.+主语+句子的其他成分。
例如：We shall never succeed，however much we try.
无论我们多么的努力，都不可能成功。
However cold it is，she always goes swimming.
无论天多冷，她总是去游泳。
