你这样 我举二个例子 你看看书，if only …………或 only if……only if表示"只有"；if only则表示"如果……就好了"。If only也可用于陈述语气。 I wake up only if the alarm clock rings. 只有闹钟响了，我才会醒。 If only the alarm clock had rung. 当时闹钟响了，就好了。 If only he comes early. 但愿他早点回来。辨析only if 与 if only only与if这两个单词随意组合，可以组成两个意义相近，但用法不尽相同的短语only if与if only。现将它们的具体用法辨析如下： 一、only if意为“only on the condition that, as long as”，“只要；假如”。它用于陈述事实或必要的条件，比if所表达的语气更强烈。 You'll pass this course only if you study. 只要你学，你就会通过这门课。 Children may enter the club only if they are accompanied by adults. 只要孩子们有大人陪同就可以参加俱乐部。 The students at the university can take up part-time job only if it doesn't interfere with their studies. 只要不影响学业，这所大学的学生可以从事兼职工作。 二、if only则有两种含义。第一种含义与only if近似，意为“as long as”，“只要”。例如： If only it clears up, we'll go. 只要天一放晴，我们就去。 第二种则是“expressing a wish or assumption”， “但愿；如果……就好了”。它用来表达一个不可能实现的愿望或假设，句子要用虚拟语气。例如： If only she would come!要是她能来就好了！ If only you had told me you had a spare ticket for the show. 如果你告诉我，你多了一张演出票就好了。 If only you had worked with greater care!你要是工作更仔细一些该多好！强调句 it is…… It is/ was + 被强调部分（通常是主语、宾语或状语）+ that/ who（当强调主语且主语指人）+ 其他部分。例子 It was yesterday that he met Li Ping.其实任何有主谓宾和主系表的句子 前边都可以加入it is 只要你写的别太牵强，一个作文用一次即可，别的也是，例如虚拟语气，用一次你擅长的即可 考试注重的是语法无误，其次是变化多，先保证句子通顺准确，再添彩，我的经验
