句型梳理
【教材原句】　If_only it could be just like last year！(P43)
要是能跟去年那样有多好呀！
【句法分析】　“if only＋句子”是一个固定句型，表示一种愿望“要是……就好了/但愿……！”
(1)if only...could/would＋do...表示对将来事情的愿望(不用should)。
(2)if only...did...表示对与目前或现在事实相反的愿望。
(3)if only...had done...表示对与过去事实相反的愿望。
①If only Marx were here by my side!
要是马克思能在我身边就好了！
②If only you had worked with greater care!
你工作要是再仔细一些该多好啊！
③If only the whole family could be united during the Spring Festival！
今年春节全家能团圆就好了！
[易混辨析]
if only，only if
(1)if only用来表达愿望，意为“但愿……，要是……就好了”，句中谓语动词要用虚拟语气(与现在事实相反用一般过去时，与过去事实相反用过去完成时)。
(2)only if由副词only和从属连词if组合而成，only仅起强调作用，意为“只要”。
①If only we could afford to buy a place of our own.
②If only you knew how hard I’ve tried to please you.
③Only if you promise not to invite Mary will I come.
④Only if you do as I told you can you succeed.
[即境活用]
8．Look at the trouble I am in！If only I________your advice.
A．followed　　　　　　B．would follow
C．had followed D．should follow
解析：选C。if only表示“如果……就好了”，表示与事实相反，条件意味强烈，其谓语动词常用虚拟语气。此句表示过去的动作，须选用过去完成时。
9．?Any information about your son?
?No.If only I________those tough words to him.
A．didn’t say
B．hadn’t said
C．shouldn’t have said
D．couldn’t have said
解析：选B。考查虚拟语气。if only“要是……就好了”。答句句意：要是我没对他说那些太严厉的话就好了。和过去事实相反，故用过去完成时。
作文指导
开放式作文
【体裁导航】
开放式作文一般不提供具体的情景，也没有固定的模式限制，但其体裁和字数仍然要受制于所提供的内容。
做此类题型的作文时，审题非常关键。还要根据所判定的体裁，打开思路，发挥想象，不要过多地顾忌是否犯了语法错误，或者表述是否清楚，而要尽快找出能合理表述文章内容的词句，一气呵成，完成作文。
一般说来，开放类作文，要求的字数比较少，所以我们在文章的结构上必须注意“集中火力”，突出重点，直奔主题，而不要随便发挥。
这样，完成了表述以后，就进入了修改阶段。看语法结构，看语言表达，看单词拼写，看标点符号，甚至看字母的大小写。总之，好文章都是经过反复修改而成的。
【写作示例】
在竞争激烈的当今社会，人们十分强调个人能力，但是我们也不能忽视相互合作(cooperation)的重要性。请举例说明相互合作的重要性。
要求：词数120左右。
【写作要领】
本题为开放式作文，要求举例说明相互合作的重要性。首先应该阐明自己赞成合作的观点，然后，举例说明。举例后的重点应该在于说明合作的重要性上。最后一段要进行总结，以达到前后的呼应。
【金点模板】
①People’s view on________.②In my opinion，________.
③Just take________.④The success________.⑤So cooperation________.
⑥I doubt whether________.⑦No matter________.⑧At the same time，________.⑨So cooperation________.
⑩All in all，________.
【范文点评】
My View on Cooperation
①People’s view on cooperation varies from individual to individual.In my opinion，cooperation to society is what air is to man.
②Just take the 2008 Nobel Chemistry Prize as an example.The success relies on the efforts of all the three scientists.③So cooperation plays a very important role in the fields of scientific research.
④I doubt whether personal efforts are enough to deal with the ever increasing challenges. ⑤No matter how great a person is, he or she cannot accomplish everything within his or her own strength. At the same time, everyone has their shortcomings. So cooperation is needed as far as the fact is concerned.
⑥All in all, as the saying goes “All roads lead to Rome” I think all rightful attempts to succeed lead to the improvement of men’s living and working standard.
【点评】
①开门见山，点明主题，提出个人观点。
②举例说明合作的重要性，富有说服力。
③据上例得出结论。
④进一步说明合作的重要性，阐明个人的能力再强大也需要合作。
⑤no matter引导的让步状语从句增强了感染力。
⑥最后给与总结，呼应开头，前后得到了很好的照应。
【类题尝试】
(2011年陕西宝鸡质检)诚信是处世之本。但是在中学生当中，考试作弊、抄袭作业、欺骗家长和老师等现象屡见不鲜。请你对以上种种现象作简要描述，并以“How to guarantee honesty”为题，从三个方面谈谈如何保证学生做到诚信。
注意：1.词数不少于100；
2.开头和结尾已给出，不计入总词数。
How to guarantee honesty
As we all know，honesty is always an essential principle of living.Much to our regret，however，________________________________________________________________________
________________________________________________________________________
Honesty is the best policy，which is what we should keep in mind all the time.
One possible version：
How to guarantee honesty
As we all know，
honesty is always an essential principle of living.Much to our regret，however，it is nothing new that some middle school students cheat in exams，copy others’ homework and fool their teachers and parents.Therefore，how to guarantee honesty should come to our attention.
Personally，I think honesty education is necessary.For instance，courses on honesty can be offered to students；activities like storytelling and lectures are also worth trying.With the concept of “being honest” rooted in their minds，honesty can be reflected in their daily life and study.
Besides，related rules and regulations should be laid down.Detailed criteria should be applied to evaluate students in aspects such as homework，tests，relationship with teachers and parents.
