Good afternoon, everybody. Welcome to this class 【小题1】 English words. I am Professor John Morris ; I 【小题2】 ( be) your teacher for the next thirteen weeks. As you can 【小题3】 ( probable) tell, this is one of the most popular — and crowded — classes; indeed, every time this course 【小题4】 ( offer), this room is very full. Why is that? Well, in order to use the English language, it is very important to have at least a basic 【小题5】( understand) of how words are formed. Just to mention one figure — and there are many — there are about one million words in English. If you are an English learner, you might wonder 【小题6】 you can possibly remember all of these words. Well, you know, there are shortcuts. For example,【小题7】 you know how words are formed by using parts of words from other 【小题8】 (language), such as Greek and French, you’ll understand a good number of English words when you first come across 【小题9】 ( they) . Let me put it this way,【小题10】 (know) the rules will help you to master a large number of words. This is probably the number one reason why this class is so popular.

Different Cultures

The cultures of the East and the West really distinguish themselves from each other a lot. 【小题1】.

The origin of the Eastern culture is mainly from two countries:China and India. Both of the two cultures are developed by rivers — the Yellow River in China and the Indus River in India. 【小题2】

When the two mother rivers gave birth to the Eastern culture，another famous culture was brought up on the Mesopotamian plain（美索不达米亚平原）一the Mesopotamian Civilization. This civilization later on developed into the cultures of Ancient Rome and Ancient Greek.【小题3】 Like the Chinese culture，the European culture also crossed waters. When the British settled down in America，their culture went with them over the Atlantic Ocean. So the American culture doesn't distinguish itself from the European culture a lot.

【小题4】 Take the language system for example. In the East，most languages belong to the pictographic language while the Western languages are mostly based on the Latin system. Other causes like human race differences count as well. But what's more，due to the far distance and the steep areas between the East and the West，the two cultures seldom communicate until recent centuries. So they grew up totally in their own ways with almost no interference（干预）from the other.

The differences are everywhere. 【小题5】 But different cultures make the world in the 21st century more varied. The cultural gap should not be the obstacle to the civilization of human beings. It ought to be the motivation for our going farther.

   There are some differences between American English and British English. Some differences are quite interesting.

When my friend Lily from London used the word "larder", I didn't know what it meant. Realizing I didn't follow her, she used another word. I finally knew she wanted to find something to keep some food.

The next word came up when we were planning a lunch date. She jotted down the date and time in her diary, while I marked my calendar. If she called me on the phone, she would ring me up. But if the line was busy, she would say the line was engaged.

Most times, I can know what Lily means. Last week, she regretted sending her boys to watch an early morning tennis game without their fleeces. I thought that she meant without their jackets or something like those. Other times, we have to ask each other. She recently told me a funny tale about a woman who was pissed. I wondered what had made the lady angry. It turns out that pissed means drunk.

Here is one more example. My British friend Jane was filling out a ticket at the grocery store（食品杂货店）recently. She asked the young man if he had a rubber. When she noticed he didn't follow her, she quickly asked for an eraser, which, in England, is often called a rubber.

In order to communicate well with the British, we Americans should learn some words that the British use differently. And I think people who learn English as a second language should also realize that there are differences between American English and British English.

   Wouldn't it be wonderful to travel to a foreign country without having to worry about the headache of communicating in a different language？

In a recent Wall Street Journal article，technology policy expert Alec Ross argued that，within a decade or so，we would be able to communicate with one another via small earpieces with built-in microphones. That's because technological progress is extremely rapid. It's only a matter of time. Indeed，some parents are so convinced that this technology is imminent that they're wondering if their kids should learn a second language.

It's true that an increase in the quantity and accuracy of the data loaded into computers will make them cleverer at translating“Noes Bueno dormer mucho” into“It's not good to sleep too much”. Replacing a word with its equivalent（对等词）in the target language is actually the easy part of a translator's job. But even this seems to be a discouraging task for computers.

It's so difficult for computers because translation doesn't — or shouldn't — involve simply translating words，sentences or paragraphs. Rather，it's about translating meaning. And in order to infer meaning from a specific expression, humans have to interpret a mass of information at the same time. Think about all the related clues that go into understanding an expression: volume, gesture, situations, and even your culture. All are likely to convey as much meaning as the words you use.

Therefore, we should be very skeptical of a machine that is unable to interpret the world around us. If people from different cultures can offend each other without realizing it, how can we expect a machine to do better? Unless engineers actually find a way to breathe a soul into a computer, undoubtedly when it comes to conveying and interpreting meaning using a natural language, a machine will never fully take our place.
