   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.

Thank you for listening！

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.
