什么是副词？副词是一种修饰动词、形容词或全句的词，说明时间、地点、程度、方式等概念。

一、副词的分类1.时间副词now, today, yesterday, tomorrow, before, soon, early等，其出现往往决定了该语句表达的时态。

Now I'm writing a letter.现在我正在写信。

I went to the park yesterday.我昨天去公园了。

I will be back soon.我很快就回来了。

2.频率副词部分频率副词频率高低的排序：always （—直）♥♥♥♥♥♥♥♥♥♥usually （通常）♥♥♥♥♥♥♥often （经常）♥♥♥♥♥♥sometimes （有时）♥♥♥♥♥seldom （很少）♥♥♥♥hardly （几乎不）♥♥♥never （从不）还有说明次数的副词，once, twice等。

频率副词经常出现在一般现在时态的语句中，表示规律性的动作或习惯。

Ben often goes to the cinema with his friend.本经常和他的朋友岀去看电影。

He never eats hamburgers.他从不吃汉堡包。

3.地点副词here, everywhere, anywhere, in, out, inside, outside, above, below, down,back, forward, home, along, round, around, near, off, past, up, away 等地点副词一般表示事情发生的地点。

He played basketball here yesterday他昨天在这里打篮球。

It's raining outside.外面正在下雨。

The toilet is over there.厕所在那里。

4.方式副词carefully, properly, anxiously, suddenly, normally, fast,well, calmly, politely, proudly, softly, warmly等一般表示事情进行的方式。

形容词的比较级定义：形容词是用来修饰物体的形状，大小，长度，属性，特点等，位于名词的前面。

而形容词的比较级表示两者间的比较。

结构：1．“A + be +形容词比较级+ than + B” 意思为“A比B更……”如：This tree is taller than that one. 这棵树比那棵树高。

注意：①在含有连词than的比较级中，前后的比较对象必须是同一范畴，即同类事物间的比较。

②在比较级前面使用much，表示程度“强得多”。

如：A watermelon is much bigger than an apple.西瓜比苹果大得多。

③ very, quite一般只能修饰原级，不能修饰比较级。

2．“become + 形容词比较级+ and + 形容词比较级”是“变得越来越……”的意思，and连接同一个形容词的比较级。

如：It becomes warmer and warmer when spring comes.春天来了，天气变得越来越暖和了。

注：表示“越来越……”时，若比较级是“原级+ er”构成的，则常用“比较级+ and + 比较级”形式；若比较级是“more + 原级”构成的，需用“more and more + 原级形式”。

如：Our school is becoming more and more beautiful. 我们的学校变得越来越美丽。

3．在含有or的选择疑问句中，如果有两者供选择，前面的形容词要用比较级形式。

如：Who is taller, Tim or Tom? 谁更高，Tim还是Tom？形容词比较级构成规律1．一般情况下，比较级在后面加；如：small → smaller short → shorter2．在重读闭音节（即：辅音＋元音＋辅音）中，先双写末尾的辅音字母，比较级加-er，如：big →bigger hot →hotter3．以不发音e结尾的单音节词，比较在原级后加；如：large →larger nice →nicer4．以“辅音字母＋y”结尾的双音节词，，比较级加；如：easy →easier heavy →heavier5．多数多音节词，比较级在前面加；如：beautiful → more beautiful different → more different6．有少数形容词的比较级是不规则的，必须熟记。
