Day after Day
A teacher was always so involved in the text being studied that he never looked up. He would call on a student for translation and explanation, and--without realizing it--he often chose the same student day after day. Out of respect, the student wouldn't point this out to him.
After being called on four days in a row, a student named Goldberg asked advice from his friends. The next day when the teacher said "Goldberg, translate and explain,”Goldberg replied, "Goldberg is absent today.”
“All right," said the teacher. "You translate and explain."

日复一日
一位老师对所讲课文总是非常投入，从不抬头。他常让一个学生来翻译和解释，并且——不自觉地——他常日复一日地叫同一个学生。出于尊敬，学生并不给他指出这一点。
一个叫古德伯格的学生，在被一连叫了四天之后，向他的朋友寻求建议。第二天，这位教师又说: “古德伯格，翻译并解释。”古德伯格回答说：“古德伯格今天不在。”
“那好吧，”老师说：“那就你来翻译并解释。”

很久以前，有一个名叫弗莱德的农夫。
long ago意为“很久以前”。

我们还常常用long, long ago(很久很久以前), once upon a time(从前)等短语开始讲述很久以前发生的事情。

3. I wish you happiness and health forever.

“wish+somebody+名词”用来表达自己对别人的祝愿。

I’d like to give you three wishes. 我想帮你们实现三个愿望。
4. Who do you think is a model student 你们认为谁是模范学生呢？

如上例所示，若画线部分的内容位于I think后的宾语从句中，在提问时要注意将疑问词置于句首，并将I think改为do you think，宾语从句的其他部分照抄，顺序不变。

三、语法讲解
1. 让步状语从句
表示让步含义的从句结构，它主要有although，though等连词引导。让步状语在句中可前置，也可后置。
前置时，强调的是主句的内容；
后置时，强调的是从句的内容。
e.g. Although/though he is tired, he still finishes his work on time.
虽然他很累，但仍然按时完成了工作。
He knows what to do， although/though he is a child.
他知道该做什么，尽管他是一个孩子。
【注意】
让步状语从句中不可再使用but等并列连词，但可以用yet，still等连接副词来加强语气。
e.g. Although/Though he worked hard at Maths, yet he didn’t pass the exam.
虽然他很努力地学习数学，但仍然考试不及格。
Although/Though her father is very old, he is still working.
虽然她的父亲年迈，但他仍然坚持工作。
【随堂小练】
【例1】 ____________it's difficult to make her dream come true, she never gives up.
A. Though B. Unless C. Because D. If
【答案】 A
【解析】 句意：尽管很难实现梦想，但她从不放弃。unless表示“除非”，because表示“因为”，if表示“如果”，though表示“虽然”，根据句意，答案选A。
【例2】
-Would you like to go to the concert with me
-I'd love to, ____________I'm afraid I have no time.
A. so B. or C. and D. but
【答案】 D
