often             60%           经常

①表示频率的副词在句子中放在动词之前，be动词之后。例如：

Mike is always happy.麦克总是开心。

②表示频率的副词提问，用how often。例如：

How often do you watch TV?你多长时间看一次电视？

Twice a month.一个月两次。

2. 名词（可数名词和不可数名词）

在英语中，名词分为不可数名词和可数名词两大类。不可数名词就是没有复数的名词；可数名词就是有单数和复数之分，两个以上的名词要用名词的复数形式。一个人或事物为单数，两个或两个以上是复数。可数名词变为复数形式的规则如下:

①一般情况是在单数可数名词后加“-s”,如a pen→pens, a sister→sisters.

②以s, sh, ch, x等结尾的单词，变复数形式需加“-es”，如：a bus→buses, a dish→dishes,

a watch→watches, a box→boxes.

③以f,fe结尾的名词，变复数形式需将f,fe变为ves,如：a knife→knives, a leaf→leaves.

④以o结尾的词多数都加-es,如:

a hero→heroes, a potato→potatoes, an echo→echoes, a tomato→tomatoes.

少数词加-s,如:

a zoo→zoos, a radio→radios, a photo→photos, a piano→pianos, a  kilo→kilos, a studio→studios.

⑤ 辅音字母+y结尾的名词，变复数形式需先将y变为i，然后再加“-es”，如：

a story→stories, a factory→factories, a family→families.

⑥复数同形的名词，如：sheep→sheep, deer→deer, Chinese→Chinese.

⑦少数名词的复数形式是不规则的，如：a man→men, a woman→women, a child→children,

a foot→feet，an ox→oxen, a mouse→mice, a tooth→teeth, a goose→geese.
