When Christopher Columbus landed on the the unnamed Costa Rica in 1502, he saw many Indians wearing gold earrings. So he thought the land must be rich in gold. He named the place Costa Rica, which means “rich coast” in Spanish.
Though little gold was found, Costa Rica today is indeed rich with coffee and bananas. Coffee is the most important product in Costa Rica and most of it is exported (出口) to other countries like America and West Germany. Bananas are the country’s second most important export.
Costa Ricans also grow many other crops such as fruits, corn and beans for their own use. Costa Ricans love colors and their houses are painted in bright colors.
Education is very important to the Costa Ricans. Almost every village has a school and education is a must for children between seven and fourteen years of age. Boys and girls go to separate (单独的) schools. Classes begin in March and end in November. The other three months of the year are harvest time and the children have to help their parents to pick coffee beans.

[用法指导] 名词分类
名词可以分为专有名词（Proper Nouns）和普通名词 (Common Nouns），专有名词是某个（些）人，地方，机构等专有的名称，如Beijing，China等。普通名词是一类人或东西或是一个抽象概念的名词，如：book，sadness等。普通名词又可分为下面四类：
1）个体名词（Individual Nouns）：表示某类人或东西中的个体，如：gun。
2）集体名词（Collective Nouns）：表示若干个个体组成的集合体，如：family。
3）物质名词（Material Nouns）：表示无法分为个体的实物，如：air。
4）抽象名词（Abstract Nouns）：表示动作、状态、品质、感情等抽象概念，如：work。
个体名词和集体名词可以用数目来计算，称为可数名词（Countable Nouns），物质名词和抽象名词一般无法用数目计算，称为不可数名词(Uncountable Nouns)。归纳一下，名词的分类可以下图表示：

(2) 可数名词（Countable Nouns）有单数与复数两种形式。

6．黄金重点：
I．以o结尾的单词一般加“s”：piano, photo, zero, radio, bamboo, tobacco, studio等。
II. 特殊需要记忆的以o结尾的单词一般加“es”：
☆ 注意：如果以O结尾的名词有生命力，则该词汇一般加 -es。

（二）不规则名词复数形式：
1. foot → feet，mouse → mice，goose → geese，child → children，
woman → women，man →men。

2．man和 woman构成的复合名词，二者均变为复数。woman teacher →______________
3．中间有连字符的合成次，在主体词（中心意义的词）末尾变复数： sister-in-law→sisters-in-law
（四）名词所有格：
表示生命含义的名词在词尾加“’s”表示所属关系，成为名词所有格。翻译：…的。
