句型梳理
【教材原句】 If_only it could be just like last year！(P43)
要是能跟去年那樣有多好呀！
【句法分析】 “if only＋句子”是一個固定句型，表示一種愿望“要是……就好了/但愿……！”
(1)if only...could/would＋do...表示對將來事情的愿望(不用should)。
(2)if only...did...表示對與目前或現(xiàn)在事實相反的愿望。
(3)if only...had done...表示對與過去事實相反的愿望。
①If only Marx were here by my side!
要是馬克思能在我身邊就好了！
②If only you had worked with greater care!
你工作要是再仔細一些該多好�。�
③If only the whole family could be united during the Spring Festival！
今年春節(jié)全家能團圓就好了！
[易混辨析]
if only，only if
(1)if only用來表達愿望，意為“但愿……，要是……就好了”，句中謂語動詞要用虛擬語氣(與現(xiàn)在事實相反用一般過去時，與過去事實相反用過去完成時)。
(2)only if由副詞only和從屬連詞if組合而成，only僅起強調(diào)作用，意為“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

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：選B�？疾樘摂M語氣。if only“要是……就好了”。答句句意：要是我沒對他說那些太嚴厲的話就好了。和過去事實相反，故用過去完成時。
作文指導
開放式作文
【體裁導航】
開放式作文一般不提供具體的情景，也沒有固定的模式限制，但其體裁和字數(shù)仍然要受制于所提供的內(nèi)容。
做此類題型的作文時，審題非常關(guān)鍵。還要根據(jù)所判定的體裁，打開思路，發(fā)揮想象，不要過多地顧忌是否犯了語法錯誤，或者表述是否清楚，而要盡快找出能合理表述文章內(nèi)容的詞句，一氣呵成，完成作文。
一般說來，開放類作文，要求的字數(shù)比較少，所以我們在文章的結(jié)構(gòu)上必須注意“集中火力”，突出重點，直奔主題，而不要隨便發(fā)揮。
這樣，完成了表述以后，就進入了修改階段�？凑Z法結(jié)構(gòu)，看語言表達，看單詞拼寫，看標點符號，甚至看字母的大小寫�？傊梦恼露际墙�(jīng)過反復修改而成的。
【寫作示例】
在競爭激烈的當今社會，人們十分強調(diào)個人能力，但是我們也不能忽視相互合作(cooperation)的重要性。請舉例說明相互合作的重要性。
要求：詞數(shù)120左右。
【寫作要領(lǐng)】
本題為開放式作文，要求舉例說明相互合作的重要性。首先應(yīng)該闡明自己贊成合作的觀點，然后，舉例說明。舉例后的重點應(yīng)該在于說明合作的重要性上。最后一段要進行總結(jié)，以達到前后的呼應(yīng)。
【金點模板】
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，________.
【范文點評】
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.
【點評】
①開門見山，點明主題，提出個人觀點。
②舉例說明合作的重要性，富有說服力。
③據(jù)上例得出結(jié)論。
④進一步說明合作的重要性，闡明個人的能力再強大也需要合作。
⑤no matter引導的讓步狀語從句增強了感染力。
⑥最后給與總結(jié)，呼應(yīng)開頭，前后得到了很好的照應(yīng)。
【類題嘗試】
(2011年陜西寶雞質(zhì)檢)誠信是處世之本。但是在中學生當中，考試作弊、抄襲作業(yè)、欺騙家長和老師等現(xiàn)象屢見不鮮。請你對以上種種現(xiàn)象作簡要描述，并以“How to guarantee honesty”為題，從三個方面談?wù)勅绾伪ＷC學生做到誠信。
注意：1.詞數(shù)不少于100；
2.開頭和結(jié)尾已給出，不計入總詞數(shù)。
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.
