英语四级大纲要求写作首尾句作文英语四级大纲要求写作首尾句作文首尾句作文是根据段首(尾)句续写短文。段首句作文也称主题句作文，因为作文题中所给的段首句往往是段落主题句。其特点是以题目为中心，一般情况下将文章分为三个段落，每段首句即为该段的主题句(topicsentences)。考生要按主题句的要求组织材料，提出论据，用一些辅助句(supportingsentences)来支持或说明主题句，写英文段首句作文要注意：所写的内容要紧扣主题，辅助句应围绕段首句续写。保证段内每个句子的内容与段首句紧密展开各个段落，如：例证、因果、定义、比较对比、程序等。要注意句与句之间，特别是段首句与辅助句之间的自然衔接。另外，所给的段首句有时是一个完整的句子，有时不是一个完整的'句子，只是句子的一部分，这就要求考生一定要审好题。找出其中表示中心思想的关键词，围绕这些关键词去扩展、描述或说明。[例1]Directions:Forthispart,youareallowed30minutestowriteacompositionaboutWomenintheModernWorldinthreeparagraphs.Youaregiventhefirstsentenceofeachparagraphandarerequiredtodeveloptheideaincompletingtheparagraph;yourpartofthecompositionshouldbeabout100words,notincludingthewordsgiven.Remembertowriteclearly.[范文]WomenintheModernWorldWomenareplayinganincreasinglyimportantroleinsociety.Successfulwomenwhoaregovernmentofficials,writers,scientists,doctorsandteacherscanbefoundeverywhere.Itistruethatmanyjobsthatonceweredominatedbymencanbedonewellbywomen.Withthechangesintheirsocialrole,women餾positioninthefamilyhasbeenimprovedaswell.Thehusbandisnolongertheonlybreadmakerinthefamilyandthewifenolongerlivesonothers.Theysharecomfortsandhardshipswitheachother.Inspiteofthesechanges,theliberationofwomenhasnotbeencompletelyrealized.Womenstillfacemanydifficultiesandobstaclesduetotraditionalrolesandlimitedeconomicstrength.Womenstillhavealongwaytogointheirstruggleforcompleteequalitywithmen.第一段首句是讲妇女在社会上的作用，因而续写的内容紧紧围绕妇女的社会作用，比如，妇女可以是************机关的工作人员、科学家、教师等;第二句的段首句是关于妇女在家庭中的地位也提高了，续写的内容也是有关夫妻患难与共;第三句的段首句是讲妇女解放仍然任重而道远，续写的部分提出了妇女所面临的问题，整个续写的部分紧扣段首句。[例2]Directions:WriteacompositionaboutWhatWouldHappenIfThereWereNopowerinthreeparagraphs,youaregiventhefirstsentenceorpartofthefirstsentenceofeachparagraph:1盓versinceearlythiscentury,electricityhasbecomeanessentialpartofourmodernlife.2盜ftherewerenoelectricpower,...3盩herefore,...[范文]WhatWouldHappenIfThereWereNoPowerEversinceearlythiscentury,electricityhasbecomeanessentialpartofourmodernlife.Ithasplayedadecisiveroleinthemodernworld.Everybodyadmitsthatdevelopmentofourc
