With the Year of the Rat coming up, I remember going out for Chinese food when I was a kid in the US. In Chinese restaurants, there are always plates with pictures of the zodiac animals (十二生肖). For most people in the US, this might be the deepest impression of Chinese culture. One time, we started to laugh after we learned that my aunt is a rat.
We laughed because in our culture, rats are animals of very low position. They eat rubbish and cary diseases, so we think they are dirty. Because rats are sneaky (鬼鬼祟祟的), we think of them as untrustworthy. Calling semeone a rat is very rude. It means we cannot trust him or her easily, or we will be cheated.
As a kid, this caused me to feel bad for people born in the Year of the Rat. I wondered whether they would be looked down upon by others. I did some research and found that although Chinese people also see rats as dirty animals, they added them to the zodiac for some reasons.
Rats are thought to be animals that can bring people wealth. They are also able to give birth to lots of babies, which makes them a symbol of good luck—traditionally, Chinese people prefer to have large families with many children. Rats are believed to have intelligence as well. It is believed that sneaky animals must be clever.
So now, I’m entering the new year with a fresh way of looking at rats. Perhaps I need to find a new understanding for other things—-animals, ideas or even people!
65．The writer gave ________ reasons to explain why Chinese people add rats to the zodiac.
A．two B．three C．four D．five
66．From the passage, we know that ________.
A．rats are animals of very low position in Chinese culture
B．Chinese children born in the Year of the Rat are looked down upon
C．rats are only seen as dirty animals in Chinese culture
D．Chinese people believe rats are sneaky but clever animals
67．According to the passage, Phrase ________ can describe someone called a rat in US.
A．油嘴滑舌 B．伶俐乖巧 C．背信弃义 D．言出必行
68．The writer mainly talks about ________.
A．why American people don’t like rats B．what Chinese people think of rats
C．how people see rats in different cultures D．who can find a new understanding for rats
