however的用法.doc

however的用法Note, however that remote sensing also involves the sensing of emitted energy and the use of non-imaging sensors.这里的however后面跟了一个that从句，我不太明白这里的however的用法，把它翻译成什么比较好？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：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。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。有时从句谓语可用情态动词。如：Dont laugh, however funny it may be. 无论多么有趣也不要笑。Ill try to finish it in time, however hard it may be. 无论多么难，我也要按时完成。“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)Id 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, its 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
