There are purple clothes, purple handbags, purple bicycles, purple furniture, even purple computers! So purple is one of the most_______colors today. But in the past, purple was a very expensive and unusual color. Let’s take a look at the rich_______of the color purple.

Some scientists believe that the first plants to appear on Earth over 500 million years ago_______looked purple, not green. Plants today are green because_______use green chlorophyll (叶绿素) to produce energy._______these early plants probably used something called retinal, which is a dark purple color.

During the time of the Roman Empire (37 BC-476 AD), it was very_______to make purple dye (染料). The dye came from sea snails (海螺) .But10,000 dead sea snails_______you just one gram (克) of purple dye… as well as a very bad smell!

I went to see this movie with my 8-year-old daughter this Tuesday，really without knowing too much about it. My daughter and I were pleasantly surprised at how funny it was. We just couldn't help laughing.1 would recommend(推荐) this movie to the whole family.-Mary

When my family moved to America in 2010 from a small village in Guangdong. China，we brought not only our luggage，but also our village rules，customs and culture. One of the rules is that young people should always respect((尊敬) elders，Unluckily，this rule led to my very first embarrassment in the United States.

I had a part-time job as a waiter in a Chinese restaurant. One time，when I was serving food to a middle-aged couple，the wife asked me how the food could be served so quickly. I told her that I had made sure they got their food quickly because I always respect the elderly. As soon as I said that，her face showed great displeasure My manager，who happened to hear what I said，took me aside and gave me a long lecture about how sensitive(敏感) Americans are and how they dislike the description“old”. I then walked back to the table and apologized to the wife，After the couple heard my reason，they understood that the problem was caused by cultural differences，so they laughed and were no longer angry. In my village in China，people are proud of being old. Not so many people live to be seventy or eighty，and people who reach such an age have the most knowledge and experience.

Young people always respect older people because they know they can learn from their rich experience. However，in the United States，people think“ growing old”is a problem since“old”shows that a person is going to retire or that the body is not working well. Here many people try to keep themselves away from growing old by doing exercises or jogging，and women put on makeup，hoping to look young. When I told the couple in the restaurant that I respect the elderly，they got angry because this caused them to feel they had failed to stay young. I had told them something they didn't want to hear. After that，I changed the way I had been with older people. It is not that I don't respect them any more: I still respect them，but now I don't show my feelings through words.
