Tea, coffee and cocoa are three major drinks all over the world. Tea is drunk by the largest number of people in the world. Tea, as well as silk and porcelain, began to be known by the world over a thousand years ago and has been an important Chinese export since then.
Tea has a history of over 4, 000 years and China is the home of tea. In ancient China, tea was used as a kind of medicine, while nowadays people drink tea daily. Longjing, Pu'er, Wulong and Tieguanyin are all famous tea. Thanks to the mild climate and rich soil in Fujian, Zhejiang and Yunnan, tea is produced mainly in these provinces.
The words for tea in different languages came from Chinese, like “cha' i” in Russian. And the Japanese character for tea is written exactly the same as it is in Chinese.
Over the past centuries, Chinese people have developed their unique(独特的)tea culture, which includes tea planting, tea-leaf picking, tea making, tea drinking and so on. Tea is also popular in some sayings, like “A friendship between gentlemen is like a cup of tea.” In dances, songs, poems and novels, tea is often mentioned, too.
A. How to speak good English B. How to put English grammar to use C. How to master English words D. How to realize the importance of English E. How to get interested in English |
①Gamaham: The most difficult thing about learning English is to remember new words. I study the words and remember them, but a week later I have forgotten most of them. When reading something in English, I always get into trouble when I come across a new word. There must be a better way to learn new words. {#blank#}1{#/blank#}
②Viekers: I have been studying English for so long now, and I don't enjoy it any more. I used to like it, but now I feel as if I'm not making any progress. I wish there was something I could do to make me interested in studying English again. {#blank#}2{#/blank#}
③Selina: I wish I could improve my spoken English. Every time I join in a group discussion or try to speak English to someone, I find it difficult to express myself. I don't know what to say and I can't think of the words I need. {#blank#}3{#/blank#}
④Gina: I don't like English at all. Why do we have to study English? I'd rather spend more time on maths and science, because I think those subjects are more important. {#blank#}4{#/blank#}
⑤Jim: I think it's easy to remember new grammar rules, but when writing something I always make a lot of mistakes. How can I learn to use the rules that I have learned? {#blank#}5{#/blank#}
A ratio compares two numbers. For example, if you have 3 pens and 4 pencils, the ratio of pens to pencils is 3 to 4. {#blank#}1{#/blank#} 3 to 4, 3:4 and 3/4. One type of ratio is expressing (表示) numbers as a percent. A percent is the ratio of a number to 100. In other words, a percent compares one number to 100. The percent means "per hundred". {#blank#}2{#/blank#} You can use "%" to express percent. So 35% means 35 out of 100, and 15% means 15 out of 100. {#blank#}3{#/blank#} Probability means the chance (可能) of some things happening in the future. For example, if there is a 90% chance of rain, 90 times out of 100, it will rain. That is a very high probability. However, if the weatherman says that there is only a 10% chance of rain, then 10 times out of 100, it will rain. {#blank#}4{#/blank#}
You can also express probability by using ratios. {#blank#}5{#/blank#} 5 of them are black while only 1 of them is red. If you choose a pen at random (随机地) from the pencil box, then the probability of choosing a black Den are 5 to 6, or 5/6. On the other hand, the probability of choosing a red pen is only 1 to 6, or 1/6.
| A. So, 60 percent of something means 60 out of 100. B. For example, perhaps you have 6 pens that all look alike in your pencil box. C. The ratio can be written in three ways. D. That is a very low probability. E. Percents are helpful when expressing the probability. |
