>>>>2015年英語(yǔ)四級(jí)作文寫作思路及練習(xí)匯總

　　2015年英語(yǔ)四級(jí)考試于6月13日、12月19日舉行，各位考生在復(fù)習(xí)英語(yǔ)四級(jí)作文時(shí)，更應(yīng)該掌握復(fù)習(xí)技巧，多加練習(xí)。下面為大家整理了英語(yǔ)四級(jí)作文寫作思路及練習(xí)，供廣大考生參考使用。

　　說(shuō)明文是用言簡(jiǎn)意賅的語(yǔ)言來(lái)介紹客觀事物，講清事理，并給人增加知識(shí)的一種文體。說(shuō)明文解說(shuō)事物的特點(diǎn)、發(fā)展變化規(guī)律，分析前因后果，目的在于使讀者“明白事理”，獲得必要的信息，對(duì)事物有個(gè)較完整明晰的了解和認(rèn)識(shí)。說(shuō)明文不同于記敘文和議論文，它重在給人介紹，讓人明白，因而，輕“情義”重事實(shí)。說(shuō)明文與議論文關(guān)系密切，有人將其統(tǒng)稱為議論文。但在寫作的目的和方法上兩者仍有區(qū)別。說(shuō)明文主要是通過(guò)事實(shí)客觀地解釋或說(shuō)明事物本身;而議論文則以事實(shí)、數(shù)據(jù)等為證據(jù)，表明主觀見(jiàn)解，使讀者信服或贊同某一觀點(diǎn)。

　　歷年四級(jí)考試中的“How I Overcome Difficulties in Learning English”、“My Ideal Job”以及圖表作文的第一段都屬于說(shuō)明文的范疇，如，2002年6月的根據(jù)坐標(biāo)圖寫題為“Students Use of Computers”的作文。

　　說(shuō)明文必須按一定的順序進(jìn)行說(shuō)明：時(shí)間順序、空間順序、邏輯順序或認(rèn)識(shí)順序，選擇具體的特點(diǎn)和細(xì)節(jié)來(lái)說(shuō)明。

　　所以，說(shuō)明文的思路要圍繞說(shuō)明順序、事物的特點(diǎn)和細(xì)節(jié)展開(kāi)。例如：

　　范文點(diǎn)評(píng)

　　A Famous Clock

　　When you visit London, one of the first things you will see is Big Ben, the famous clock which can be heard all over the world on the B.B.C. If the Houses of Parliament had not been burned down in 1834, the great clock would never have been erected. Big Ben takes its name from Sir Benjamin Hall who was responsible for the making of the clock when the new Houses of Parliament were being built. It is not only of immense size, but is extremely accurate as well. Officials from Greenwich Observatory have the clock checked twice a day. On the B.B.C. you can hear the clock when it is actually striking because microphones are connected to the clock tower. Big Ben has rarely gone wrong. Once, however, it failed to give the correct time. A painter who had been working on the tower hung a pot of paint on one of the hands and slowed it down!

　　【點(diǎn)評(píng)】這是《新概念英語(yǔ)》中的一篇經(jīng)典說(shuō)明文，介紹了世界著名的“大本鐘”。文章開(kāi)篇指明該鐘位于英國(guó)倫敦，且全世界的人們通過(guò)BBC就能夠聽(tīng)到鐘聲。接下來(lái)講述了“大本鐘”的由來(lái)，特點(diǎn)——不僅外型巨大，而且走時(shí)準(zhǔn)確，在結(jié)尾處講了“大本鐘”的一個(gè)幽默的小插曲——油漆工把油漆桶掛在指針上，把鐘弄慢了。細(xì)讀這篇文章，我們不難發(fā)現(xiàn)，區(qū)區(qū)159個(gè)單詞就把“大本鐘”的光輝形象牢牢地刻在讀者的腦海里，為什么?本文基于事實(shí)，分析了主題的來(lái)龍去脈，語(yǔ)言簡(jiǎn)潔又不失生動(dòng)貼切，作者態(tài)度客觀又充滿幽默，使讀者既“明白了事理”，又對(duì)事物有較完整明晰的了解認(rèn)識(shí)，此乃說(shuō)明文之真諦也。

　　以“Goals”為題打開(kāi)一篇說(shuō)明文的思路。

　　參考思路

　　1)目標(biāo)的分類：(可根據(jù)時(shí)間順序，空間順序、邏輯順序或認(rèn)識(shí)順序，任選一個(gè)進(jìn)行分類和排列)

　　2)各個(gè)類別的特點(diǎn)和細(xì)節(jié)：

　　3)組織成文：

　　范文點(diǎn)評(píng)

　　Goals

　　Everyone has goals. Many people do not reach their goals for lack of planning. These three sets of goals should be developed: lifetime, intermediate and short term.

　　Lifetime goals should be written out. These goals should be clear and reasonable. For instance, the goal to win a research prize is clear and measurable. Other lifetime goals might include publishing a certain number of influential books or articles, earning a departmental chairmanship at a major university, successfully competing for a grant from the National Science Foundation or securing a consultantship with a big corporation.

　　Intermediate goals relate to outcomes during the next few years. For the beginning doctoral student, intermediate goals may include completion of course work and preparation of a doctoral research proposal. Like lifetime goals, these are measurable and clearly stated.

　　Short-term goals involve outcomes expected during the next 12 months. These goals are more performance oriented, and they help with achievement of intermediate goals. Examples of short-term goals are earning an A in a course, learning how to program a computer or performing an experiment.

　　說(shuō)明文的說(shuō)明方法

　　對(duì)這些方法我們要了解并且掌握：

　　1. 定義法(definition)

　　定義法是用下定義的方式去揭示事物本質(zhì)特征或概念內(nèi)涵。它能使讀者迅速抓住本質(zhì)屬性和基本特點(diǎn)。此法的句型：

　�、� … is a/the … of … which/that …② … relate to/involve/refer to …

　　【例】

　　(1)Language is a system of arbitrary vocal symbols which is used for human communication. 語(yǔ)言是人類用來(lái)交際的任意性的語(yǔ)音符號(hào)體系。

　　(2)Intermediate goals relate to outcomes during the next few years.

　　(3)Short-term goals involve outcomes expected during the next 12 months.

　　2. 舉例法(illustration)

　　舉例法就是舉出實(shí)際事例來(lái)說(shuō)明事物的方法，是最常見(jiàn)，往往也是最有效的闡釋模式。

　　專家提醒

　　舉例時(shí)應(yīng)挑選具體、典型且有能力表達(dá)清楚的例子，并注意按照一定的順序編排。

　　請(qǐng)看上述范文第二段：“For instance”引出“l(fā)ifetime goals”的實(shí)例，如，贏得研究獎(jiǎng)金、出版有影響書(shū)或文章、獲得大學(xué)的系主任職位、獲得國(guó)家自然科學(xué)基金及大公司穩(wěn)定的顧問(wèn)職位。

　　3. 分類法(classification)

　　分類法就是把說(shuō)明的對(duì)象，按一定的標(biāo)準(zhǔn)劃分成不同類別分別加以說(shuō)明的方法。如：上述范文介紹人生的三種目標(biāo)，并按照時(shí)間的長(zhǎng)短對(duì)終生目標(biāo)、長(zhǎng)期目標(biāo)和短期目標(biāo)做了分類說(shuō)明。

　　4. 比較法(comparison)

　　比較法是用一個(gè)事物和與其有聯(lián)系的其他事物加以對(duì)比的說(shuō)明方法。目的是為了幫助讀者準(zhǔn)確地區(qū)分事物，通過(guò)對(duì)比達(dá)到對(duì)該事物的深刻認(rèn)識(shí)。

　　如：上述范文對(duì)三種人生目標(biāo)在時(shí)間上和實(shí)際操作上進(jìn)行了比較，并闡明了彼此的聯(lián)系。

　　(1)Lifetime goals should be written out.

　　(2)Like lifetime goals, these are measurable and clearly stated.

　　(3)These goals are more performance oriented, and they help with achievement of intermediate goals.

　　5. 數(shù)字法(statistics)

　　數(shù)字法是運(yùn)用數(shù)據(jù)來(lái)表明事物的本質(zhì)和特點(diǎn)，準(zhǔn)確合理的數(shù)據(jù)使文章精確可信。

　　【例】

　　(1)Nearly half of all Americans over age 20 wear a bridge or denture，and more than 20 percent have complete upper and lower denture. By age 50, one out of every two persons has gum disease.

　　(2)And it seems sensible to wait. One quarter of all marriages between people under twenty-one end in divorce. In Britain in 1972, there were 124,248 divorces.
