If only I had gone to the airport by taxi.我没有赶上飞机。要是我乘出租车去机场就好了！辨析 if only 与 only if：if only表示“要是就好了”。only if是“only+状语从句”位于句首的倒装结构。If only I had seen the film!要是我看过这部电影就好了！Only if I get the job will I have enough money to go to school.只有我得到这份工作，我才会有足够的钱上学。3 .(教材 P9) I think it's important to understand that there*s no such thing as a good or a bad student.我觉得明白没有好学生或是坏学生这类说法是重要的。此句含有 There is no such.as.句式。“There is no suchas” 句式“There is no suchas.”是固定句式，表示“没有像的”。其中的“nosuch+可数名词单数”相当于"not such a/an+可数名词单数”。such 与 all, no, some, any, few, little, many, much, several, one 等词连用时， 应置于 这些词之后，其后的名词前无冠词，如：no such man, several such rooms.For the unenlightened people, there is no such thing as study.对于那些无知的人来说，没有学习这回事。注意：(1) such与a/an连用时要放在a/an的前面。(2)如此以至于such a/ an + adj. +可数名词单数+ thatsuch + adj. +不可数名词/复数名词(3) such.as. “像这样的”，as在句中引导定语从句语法解析语法：过去完成时过去完成时由“had done”构成，其用法如下：1 .表示在过去某一时间或某一动作之前完成的动作或存在的状态，即“过去的 过去”。一般可通过表示“过去的过去”的时间状语(从句)或上下文的语境来 判断。When walking down the street, I came across David, whom I hadn't seen for years.我走在街上时，碰到了多年没见的大卫。2 .表示从过去某一时间开始，一直延续到过去的另一时间的动作或状态。 常用的时间状语有：before, by then, by that time, by the end of, by the time 等。It took me a long time before I was able to fully appreciate what they had done for me.我花了很长时间才能完全理解他们为我所做的。3 .表示“愿望，打算”的动词(mean, plan, intend, expect等)用过去完成时，表 示原本打算实现却未如愿。I had intended to call on you yesterday, but I had an unexpected visitor.我昨天本来打算给你打电话的，但不料来了一位客人。4 .常使用过去完成时的句型：(1) This/ That/ It was the first/ second/ third.time that.that从句的谓语动词用过去完成时This was the first time that they had met in thirty years.这是他们三十年来第一次见面。(2) It was+一段时间+since 从句 since从句的谓语动词用过去完成时It was ten years since we had had such a wonderful time.自我们曾度过一段如此美妙的时光以来，已经过去十年了。(3)用于表示“一就”的句型中：Hardly had sb. done.when.did.;No sooner had sb. done.than.did.Hardly had she gone to bed when the bell rang.她一上床睡觉铃就响了。No sooner had I sat down than there was a loud knock on the door.我一坐下来就有人大声敲门。练习：1.
