　　The discussion about electronic dictionaries has never stopped in the past few years. Let's have a look at its advantages and disadvantages before drawing the final conclusion.

　　The biggest advantage of an electronic dictionary is its convenience. Whenever you meet new words or expressions, you can know the meaning quickly. What's more, with the development of science and technology, electronic dictionaries are becoming more and more advanced: they can pronounce the words clearly, provide sample sentences to illustrate word usage and store difficult words for special memorization. Last but by no means the least, electronic dictionaries are becoming cheaper and cheaper, and more and more students can afford them.

　　However, the negative effects are also obvious. To begin with, some students rely too much on the electronic dictionary—they never put their heart into learning new words and expressions. In the second place, some explanations are neither complete nor accurate, which are quite misleading. Finally, new technical inventions do not necessarily lead to progress in learning. Diligence is always the decisive factor, because "there is no royal road to learning".

　　Up until now, we can see it clearly that an electronic dictionary is not beneficial or harmful in itself. The key lies in the user—so long as we can make proper use of it, it can be most helpful to us in many respects.

　　重點講析：

　　首段提出一個長時間爭論的話題;第二段中指出該事物的優(yōu)點;第三段闡述缺點;第四段首句下結(jié)論，表明此事物本身無對錯，第二句指出關(guān)鍵在于使用者，即如果合理使用，就會從中受益。

　　范文首段指出，有關(guān)電子辭典的討論從來沒有停止過;第二段闡述優(yōu)點，即電子辭典便于查詢，而且隨著技術(shù)的發(fā)展，電子辭典功能也越來越多，另外價錢也越來越低;第三段提出缺點，電子辭典讓學(xué)生產(chǎn)生依賴心理，而且有些解釋不準(zhǔn)確，另外技術(shù)的進(jìn)步不一定帶來學(xué)習(xí)上的進(jìn)步;最后一段總結(jié)，電子辭典本身無對錯，關(guān)鍵在于正確使用以便為我們服務(wù)。

　　第二段第三句中的illustrate表示“用圖或例子來說明”;第三點中的afford表示“買得起”。第三段第一點中的rely too much on表示“過分依賴”;put one's heart into doing sth.表示“專心致志于某事”;第二點中的accurate表示“精確的”，misleading表示“使人誤解的”;第三點第二句中的decisive factor表示“決定因素”。

　　Recently it seems that among the students who choose to study abroad, there are more and more-teenagers who study in high schools or even elementary schools. Many people, especially the parents, think it will certainly do good to their chidren because the independent life will make them learn confidence and perseverance. Moreover, the quality of overseas education is often higher, thus the child stands a better chance of entering a better university and getting a better job in the future.

　　After careful consideration, I have to say the above view is more than biased. On the one hand, early independent life is not necessarily good, if the child cannot receive proper guidance and tender care from both teachers and parents. On the other hand, the educational quality is also a question—too many foreign schools aim at earning money. When the children come back, who can guarantee that they can adapt to the fierce competition here?

　　We can see clearly that although teenagers' studying abroad may bring favorable results, there are still a lot to worry about. It seems necessary for young students to make a careful investigation before going abroad.

　　重點講析：

　　第一段指出當(dāng)前某種普遍的做法，之后分兩點闡述人們支持這種做法的原因;第二段首句鮮明地指出自己反駁的意見，然后分兩點來闡述理由;最后一段進(jìn)行總結(jié)，并請當(dāng)事人在做出決定前多加斟酌。

　　范文首句點題，指出青少年留學(xué)這一現(xiàn)象，并給出支持者的理由，即獨立的生活會教會他們自信和堅持不懈，而且國外的教學(xué)水平會讓學(xué)生進(jìn)入更好的大學(xué)、找到更好的工作。第二段給出反對理由。首先，早期獨立不一定是件好事。另外，太多的國外學(xué)校的目標(biāo)是掙錢，所以它們的教學(xué)質(zhì)量是令人質(zhì)疑的。末段總結(jié)說青少年留學(xué)可能會帶來好處，但令人擔(dān)憂的問題也很多。

　　第一段第三句中的stand a better chance of表示“有更好的機(jī)會做某事”。第二段首句中的biased表示“偏激的，存有偏見的”;第三句中的aim at表示“目的在于”;第四句中的guarantee表示“保證”，adapt to表示“適應(yīng)”，fierce表示“激烈的”，修飾competition(競爭)。
