The American computer company IBM says it has developed a microprocessor – a computer chip – that works much like the human brain. 

美國計算機公司IBM表示，它開發了一種微處理器 - 一種電腦芯片，其功能與人類的大腦一樣。

IBM calls the chip True North. It is the size of a postage stamp. 

IBM稱芯片True North。這是郵票的大小。

The chip has 5.4 billion tiny parts that work like the human brain’s neurons and synapses.   

該芯片擁有54億個微小部分，像人腦的神經元和突觸一樣工作。

Neurons and synapses are the cells and electric forces that carry messages to and from the brain. 

神經元和突觸是將信息傳遞到大腦的細胞和電力。

True North has 1 million neurons and 256 million synapses. 

True North 有100萬個神經元和2.56億個突觸。

The human brain has 100 billion neurons and up to 150 trillion synapses.

人腦有1000億神經元和150萬億突觸。

IBM says it can program the new chip to understand difficult problems and then solve them as humans would. 

IBM表示，它可以編程新的芯片來了解困難的問題，然後像人類那樣解決它們。

The company says the True North chip could be used as a brain for search-and-rescue robots. 

該公司表示，True North芯片可用作搜索和救援機器人的大腦。

It can also be used for controlling new kinds of wheel chairs or for recording conversations involving several people and then making a printed record of those conversations. 

它也可用於控制新型輪椅或用於記錄涉及幾個人的對話，然後製作這些對話的打印記錄。

True North is still being tested. 

True North仍在測試中。

But IBM says it could be available for public use in two to three years. 

但是IBM表示在兩到三年內可以公開使用它。

The chip is just one example of machines becoming more and more like humans. 

該芯片只是機器越來越像人類的一個例子。

This field of study is called artificial intelligence, or AI. 

這個研究領域被稱為人工智能或簡稱AI。

Some experts believe computers will someday become more intelligent than humans.

有專家認為，電腦有一天比人類更聰明。
