【文体指导】1．议论文的结构和上下文的连贯性对于议论性的作文，其结构要自然地形成主题、扩展和结尾这样的三段式结构。
开头句往往是主题句，主题句要做到内容完整、概括性强、表达清楚、突出主题。
一般说来，一篇议论文讨论的是一个主题，其焦点只有一个，要做到主题的统一性。
其次上下文的连贯性也很重要，做到段落中的句子之间相互联系、相互依存、上下一体，也就是逻辑关系要一致。
另外，适当地利用一些连接词和过渡词会增强段落的连贯性。
2．议论文段落的基本结构议论文段落的基本结构：主题句(topic sentence)、阐述句(supporting sentence)和结尾句(concluding sentence)。
(1)主题句：包括段落的主题和中心思想，一般置于段首，偶尔也置于段中或段末，并不是所有的段落都有主题句，有的段落的主题内容是分散的。
(2)阐述句：通过具体而有说服力的事实来展开主题。
(3)结尾句：是对段落的概括、总结或是对主题的评论和建议，以增强回味的余地。
【常用句式】1．We have a discussion about...2．We have had a survey on...3．Opinions are divided on the question.4．Opinions are mainly divided into two groups.5．Others have different opinions.6．First/Firstly，second/secondly，third/thirdly，finally，then，next，in addition，furthermore，besides，what's more...7．It's well known that/everyone knows that/some people think that/It seems obvious that...8．In my opinion/view，as far as I know，in conclusion，in short，at last，in other words...【写作任务】人们对于学生网上交友持不同意见。

“mustn't”不准。
2. It ________ have been her to leave her child alone. She isn't such a person.答案：couldn't couldn't表示对过去的否定推测。
3. It was my fault. I ________ (tell) you about the meetingearlier.答案：should have told表示“本应该做但没有做”，用should have done。

5. I couldn't ________ (go) through that bitter period without your generous help.答案：have gone表示对过去情况的虚拟，应用情态动词＋完成式。

7. ________ (persuade) him not to do so, he wouldn't have made such a serious mistake.答案：Had I persuaded句意：要是我事先说服他不那么做的话，他就不会犯这么严重的错误了。
题干中主句的谓语部分为wouldn't have made，表示该动作与过去事实相反，故条件句用had done的虚拟结构，条件句中有had且省略if时，要将had提到主语之前。
8. If I ________ (learn) my lessons hard, I wouldn't have failed in the final exam.答案：had learned根据主句中的“wouldn't have failed”可知，从句叙述过去的情况，故用过去完成时。
9. Look at the trouble we're in. If only we ________ (take) ourteacher's advice!答案：had taken后一句句意：要是我听从了老师的建议多好！表示与过去情况相反的虚拟，用过去完成时。
10. —How I wish I had studied harder when I was in senior school!—If you had, you ________ (be) a university student now.答案：would/could/might/should be句意：——我多么希望在高中的时候学习能再努力点啊！——如果你努力点学习，现在你就是一个大学生了。
本题中从句是对过去的虚拟，主句中有时间状语now，是对现在的虚拟，所以用“would/could/should/might＋动词原形”的形式。
