问题 问答题 简答题

假设由哪两类变量构成?举例说明如何确立这两类变量。

答案

参考答案:

假设由两类变量构成:自变量和因变量。自变量指起影响作用的因素,一般用x表示。因变量:被影响的因素,一般用y表示。

自变量和因变量的确立取决于研究的目的:如果研究说话人的社会属性和他所用语言的特征之间的关系时,通常社会属性是自变量,语言特征是因变量。即社会属性影响他的语言特征。如果划定某种语言变体的使用范围去研究说话人的社会特征,那么语言变体就变成了自变量,说话人的社会特征就是因变量。即语言变体反映了他的社会特征。

     Five Olympic mascots were announced exactly 1000 days before the Beijing Olympic opening

ceremony. The long-anticipated mascots represent four of China's most popular animals—the fish, the

panda, the Tibetan antelope and the swallow. The fifth mascot is the brightly burning Olympic flame.

     Each of the mascots has a repeated two-syllable name. This type of name is a traditional way of

showing affection for children in China. BeiBei is the fish, JingJing is the panda, HuanHuan is the Olympic

flame, YingYing is the Tibetan antelope and NiNi is the swallow. The first characters of their two-syllable

names read "Beijing Huanying Ni," or, in English, "Welcome to Beijing."

     The five elements of nature, including the sea, forest, fire, earth and sky are found in the mascot's

origins and headpieces. These special headpieces also display the folk and culture of China. Each mascot

also symbolizes a different blessing —prosperity, happiness, passion, health and good luck.

     It is the first time more than three mascots will share the important duty of representing their host

country. Han Meilin, chief of the mascot design team explained that, "China has such a rich culture that no

single mascot could possibly represent it! That is why we chose to produce five mascots instead of one."

     Called the "Five Friendlies," the figures embody(体现) the Chinese people's hope for peace and

friendship in the world and the spirit of the Olympics, representing not only multi-ethnic(多民族的)

cultures of China, but also the traditional Chinese philosophy of harmony between humans and nature.

     In order to help Beijing 2008 spread its theme of One World, One Dream to every continent, the Five Friendlies reflect the deep desire of the Chinese people to reach out to the world in friendship through the Games - and to invite every man, woman and child to take part in the great celebration of human union in

2008.
