【題目】24 Solar Terms: Tips you may not know about Cold Dew

關(guān)于寒露，你可能不知道的小知識(shí)

The traditional Chinese lunar calendar divides the year into 24 solar terms. Cold Dew, (Chinese: , the 17th solar term of the year, begins this year on Oct 8 and ends on Oct 23.

At this time, temperatures are much lower than in White Dew in most areas of China. The dew is greater and colder and there will be less rain. Autumn crops will be ripe.

Here are eight things you should know about Cold Dew.

Foggy autumn

Temperatures drop significantly in October. When the cold air encounters autumn rain, the abundant water vapor in the air soon reaches saturation, and then it turns into misty rain or fog. When the humidity is high, there will be foggy regions formed in many areas of China.

Season for fishing

People always say that fishing in shallow water in autumn does make sense. That’s because during the Cold Dew period, temperatures decrease quickly and sunshine cannot reach the deep water thoroughly. Fish all swim to shallow water areas where the water temperature is relatively high.

Season for eating pomegranates

Pomegranates are ripe during Cold Dew. Pomegranates have been cherished for their exquisite beauty, flavor, color, and health benefits for centuries.

Season for drinking chrysanthemum wine

Chrysanthemum is the iconic flower of Cold Dew. To prevent autumn dryness, many regions in China have the custom of drinking chrysanthemum wine. This is a tradition of the Double Ninth Festival (on the ninth day of the ninth month in the Chinese calendar), which often falls around Cold Dew. According to ancient records, drinking the wine made with chrysanthemums, poria cocos and pine oleoresin grants people long lasting youth.

Season for eating hawthorns

There is a saying that goes "It is time to harvest hawthorn during Cold Dew." Extracts of the berries have long been used in herbal medicine. The antioxidants in hawthorn are thought to boost heart health by strengthening blood vessels and stimulating blood flow.

A great time for hiking

During Cold Dew, North China takes on a look of late autumn with white clouds, red leaves and early frost. On the day of the Double Ninth Festival, people often climb hills with cornels, a kind of plant. This custom aims to dispel evils, and originated in the Eastern Han Dynasty (AD25-220).

Season for making kippers

People of the Dong ethnic group in western Hunan province have the custom of making kippers during Cold Dew. It is said that the kipper made on the day of the Cold Dew with accessory foods such as rice wine, salt, glutinous rice, pepper powder, paprika powder and ginger are especially delicious.

Season for picking camellia seeds

Southern Hunan province is a famous area for producing tea seed oil. People are not allowed to go to the mountains to pick the seeds until Cold Dew comes around.

【1】How many tips are mentioned in the passage?

【2】w hen the temperatures are much lower in moa area of his in old Dew or in White Dew?

【3】Why do people always say fishing in shallow water in auturmn does make sense?

【4】What are pomegranates famous for?

【題目】

Apple’s logo is one of the most familiar icons(圖標(biāo)) around the world. But what’s the story about the Apple logo? The image of the apple is obvious, because that’s the name of the company. What about the bite? The famous story is that the logo shows respect and honour for Alan Turing. He was the father of computer science. He researched artificial intelligence(人工智能) and unlocked German wartime codes(密碼). However，after the war, he was put into prison，because of his beliefs. He could not stand the looking down and chose to bite a poisoned apple to end his life in the prison.

However, Rob Janoff, who designed the famous Apple logo, said, “It’s not the truth, but only a legend(傳說, 傳奇). The real reason why I designed it with a bite is very simple. I wanted people to get that it was an apple not a cherry (櫻桃). When I go to markets to buy apples, I always mistake apples for cherries. It really has nothing to do with the scientist.”

Are you kidding? An apple is much bigger than a cherry. It’s very easy to tell. But if you use an apple to design a logo, some people may mistake it for a cherry.

【1】Both the apple and the cherry are almost the same actually in ________.

A. shape B. size C. colour D. weight

【2】According to the passage, Alan Turing________.

A. died in the prison B. used an apple to design a logo

C. was put into prison during the war D. was the father of a computer company

【3】What’s the purpose of writing the passage about the apple logo?

A. To introduce its designer. B. To tell us a legend about it.

C. To try to find the truth of it. D. To explain its market research.
