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. |
English is the first language of several countries. However, it has many differences. British, American, and South African English are all spoken differently. In many English language courses, the British and American differences are taught. There are important differences between the two.
Probably the biggest difference between American and British English is the vocabulary. Different words and expressions are used to talk about the same thing. For example, in the United States, people throw their garbage into the trash can. In England, people throw their rubbish into the dustbin. In Britain, people take a lift to the fifth floor. In America, people take an elevator.
American and British grammar can be also different. For example, speakers of British English will ask "What did you do at the weekend?", but Americans usually say "on the weekend." In the United States people usually say "I've gotten a new car.", but in the UK they will say "I've just got a new car."
The pronunciation in American and British English is also different, even when the spelling is the same. The word "tomato"—pronounced "to-mah-to" in British English—is a classic example of this.Vocabulary, grammar, and pronunciation are three ways English is different in different parts of the world.
Learning all these is not easy, so English learners should just know that they are always there.
