英語學習者最先接觸到的連詞，恐怕非and莫屬。它用于連接單詞或句子中的并列部分，有“和、與、同”之義。總結起來，and主要有以下幾種用法：

表語義增補：He has two books and three pens.

表轉折：She is Jack of all trades and master of none.

表順序：He came in and took his coat off.

表因果：The girl couldn’t find her mother and began to cry.

表結果：Try again and you will succeed.

表對比：Lily likes music and Lucy is fond of reading.

表評注：She always looks down on others, and I don’t like this.

表目的：She will come and see me tomorrow. (主要用于go, come,try,stay等動詞前，代替to)

表“加上”：2 and 2 makes 4.

表反復或連續：She tried and tried but failed.

表差別：I like city life but there are cities and cities.

還需要注意的是， “good/nice/fine + and + 形容詞 (或副詞)” 是一個強調句式，常用于口語。good/nice/fine + and有“很，非常”的意思，相當于 very 的作用。例如：

My bedroom is nice and warm. 我的臥室很溫暖。(不是“我的臥室又好又溫暖”。)
