Hello，大家好！歡迎來到「新概念英語的教與學」！我是上海時學教育的鐘老師。
【往期回顧】
下面是我們每周一課一題一語法的分享時間，先來公布上一期課後一題的答案及簡析：
【簡析】通過讀題幹可知，題目主要考比較關係「不同的」表達法，讀題幹可知：be different from 表示「與……不一樣，不同」, 還可以說成 「 be not the same as」， 所以此題答案為A，整句話翻譯為：「這不同於現代的汽車。」上一期分享的文章，大家可以點擊這裡回看：

【本期內容】
下面我們繼續本周《新概念英語2》第57課的重點句型或語法的分享。先來讀一讀課文：
一、課文原文
Lesson 57 Can I help you, madam?
A woman in blue jeans stood at the window of an expensive shop. Though she hesitated for a moment, she finally went in and asked to see a dress that was in the window. The assistant who served her did not like the way she was dressed. Glancing at her scornfully, he told her that the dress was sold. The woman walked out of the shop angrily and decided to punish the assistant next day. She returned to the shop the following morning dressed in a fur coat, with a handbag in one hand and a long umbrella in the other. After seeking out the rude assistant she asked for the same dress. Not realizing who she was, the assistant was eager to serve her this time. With great difficulty, he climbed into the shop window to get the dress. As soon as she saw it, the woman said she did not like it. She enjoyed herself making the assistant bring almost everything in the window before finally buying the dress she had first asked for.

二、重點句型或語法
本課主要學習介詞 at/ in/ off/ with 的用法。
（1）本課側重at後接地點的用法，注意at 後面主要接的是城市站點，A large crowd waswaiting at the bus stop. On the way home, we stopped at a small village called Puddletom.（2）本課側重的是in後接地點的用法，注意in後面主要接城市或國There were a lot of people in the street..街上有許多人。
He lives in Berlin.
（3) 「 in + 顏色或衣服」 可以表示「穿著」 。例如：
The lady in red is my Chinese teacher.
穿著紅色衣服的是我的語文老師。
He was dressed in a black suit .
他穿著一套黑色衣服。
（3) off也常接方位地點，有時可以作為副詞，後面無需再跟賓語。例如：
The lid came off easily.
這個蓋子很容易掉。
The pencil rolled off the table.
鉛筆滾到桌子下面去了。
Take your coat off.
把你的外套脫下來。
（4) 本課側重with 用來表伴隨的用法。 例如：
The woman with the brown handbag and long umbrella is a famous novelist.
那個手上拿著棕色手提包和長柄雨傘的女士是一位著名的小說家。
That man with long hair is supposed to be a poet.
那個留著長頭髮的男人應該是一位詩人。
