The goal of early calculating machines was to simplify difficult sums. But with the help of new technology, electronic chips replaced tubes and a revolution of artificial intelligence has arisen. From then on, the appearance of computers totally changed our lives. They can not only download information from the net when connected by the network or mobile phone signals, but also solve different types of logical problems.

早期計算機器的目的是簡化比較難的計算。但是在新技術(shù)的幫助下，電子芯片代替了電子管，一場人工智能革命由此掀起。從那時起，電腦的出現(xiàn)完全改變了我們的生活,它們不僅能在網(wǎng)絡(luò)或移動電話信號的連接下從網(wǎng)上下載信息，而且可以解決各種類型的邏輯問題。

With operators as their coaches, they can even control rockets to explore the moon and instruct androids with the human race's characters to mop floors and watch over your naughty niece. Anyhow, computers are so helpful that they do bring happiness.

However, computers are easily attacked by viruses.This reality has become a hard-to-deal-with-problem. As a result, computers are dangerous in a way.

在操作員的教練下，它們甚至還可以控制火箭探索月球，指導(dǎo)具有人類性格的機器人擦洗地板和照顧你調(diào)皮的侄女。不管怎么說，電腦都是如此的有用，以致的確給人們帶來了快樂。

然而，電腦很容易受到病毒的攻擊，這一現(xiàn)實已經(jīng)成為一個難以處理的難題，因此，電腦在某種程度上是很危險的。
