我会在二楼给出对各位筒子练习的评点，同时针对大家练习中出现的语法弱点进行第二天的复习。练习完毕后，请去NCE3小组更正错误以及讨论^^

ahu参加宝宝大赛以来，第一次坚持自学新概念这么久（整整20课啊55）。现在虽然宝宝爬行比赛结束了，但是宝宝不能一辈子都爬滴，宝宝的成长是不能忽视滴，所以21课以后的内容还是要继续滴。
暂定每周1、3、5新课文，2、4、6复习头天内容，周日回顾本周内容。作业大部分是翻译【因为当你跟老外打交道的时候他是不会出选择题或者填空题给你做的】，参考答案我会放在NCE3小组，请大家踊跃讨论【请大家不要勾选楼主可见，咱们做练习为的就是讨论复习，不是完成作业】。Ahu一直认为复习讨论比学习更加重要，欢迎大家踊跃提问，踊跃讨论！【有红包奖励的哦！】
Ahu的主持风格大概跟以前主持不一样，不过好歹也是原创。【大家慢慢适应，吐啊吐啊就习惯了^.^】课文中这种方括号大概会出现很多【没准哪天大家的名字也会出现其中】，主要是为了调节气氛活跃大脑加深印象，喜欢的筒子们举手欢迎下，不喜欢的就举脚唾弃下或者跳过。总之两个字：“无论什么方法，学习了消化了就是自己的了^.^”【众人的臭鸡蛋烂番茄＋板砖纷纷扔上台：这是两个字嘛？不会数数就下去！】
言归正传，lesson 23开始：

People become quite illogical when they try to decide what can be eaten and what cannot be eaten. If you lived in the Mediterranean, for instance, you would consider octopus a great delicacy. You would not be able to understand why some people find it repulsive. On the other hand, your stomach would turn at the idea of frying potatoes in animal fat -- the normally accepted practice in many northern countries. The sad truth is that most of us have been brought up to eat certain foods and we stick to them all our lives.
No creature has received more praise and abuse than the common garden snail. Cooked in wine, snails are a great luxury in various parts of the world. There are countless people who, ever since their early years, have learned to associate snails with food. My friend, Robert, lives in a country where snails are despised. As his flat is in a large town, he has no garden of his own. For years he has been asking me to collect snails from my garden and take them to him. The idea never appealed to me very much, but one day, after heavy shower, I happened to be walking in my garden when I noticed a huge number of snails taking a stroll on some of my prize plants. Acting on a sudden impulse, I collected several dozen, put them in a paper bag, and took them to Robert. Robert was delighted to see me and equally pleased with my little gift. I left the bag in the hall and Robert and I went into the living room where we talked for a couple of hours. I had forgotten all about the snails when Robert suddenly said that I must stay to dinner. Snails would, of course, be the main dish. I did not fancy the idea and I reluctantly followed Robert out of the room. To our dismay, we saw that there were snails everywhere: they had escaped from the paper bag and had taken complete possession of the hall! I have never been able to look at a snail since then.

1、..for instance, you would consider octopus a great delicacy.
for instance = for example. (举例来说)
for instance, 更书面一些，更淑女一些。
For example, people infected with the AIDS virus often develop tuberculosis(肺结核)。例如，感染了爱滋的人通常也会出现肺结核病况。
For Instance, people infected with the AIDS virus often develop tuberculosis.
有例为证，感染了爱滋的人通常也会出现肺结核病况。【ahu要举例，不说“例如”，而是说“有例为证”，是不是显得更有学问一些？其实老外也蛮会拽文滴！】

4、.. have learned to associate snails with food.
用法：associate A with B，把A和B联系在一起。

用法：Though we have bought the house, we won’t take possession of it until the present occupants move out.

难句&美句：

1、Cooked in wine, snails are a great luxury in various parts of the world.
因为是被动，所以过去分词cooked修饰snails。比较：
Cooking snails, I feel hungry.

2、There are countless people who, ever since their early years, have learned to associate snails with food.
ever…插入在句子中间是为了强调。

3、For years he has been asking me to collect snails from my garden and take them to him.
have been asking，现在完成进行时，强调过去就开始要，现在还在要，以后还继续要。。【蜗牛对他的朋友真的有这么重要吗？】

4、Robert was delighted to see me and equally pleased with my little gift.
