People in different countries have different ways of doing things. Something is 16 in one country, but it may be quite impolite in another. In Britain, you mustn’t lift your bowl to your 17 when you are having some liquid(液体) food. But it’s 18 in China. And in Japan you even needn’t worry about making 19 while you are having it. It shows that you’re enjoying it. But people in Britain think it is bad manners. If you are a visitor in Mongolia, what manners do they wish 20 to have? They wish you to have a loud “burp”(打嗝) 21 you finish eating. Burping shows that you like the food.

In Britain, you should try not to 22 your hands on the table when you’re having a meal. In Mexico, however, guests may keep their hands on the table during a meal. But in Arab(阿拉伯) countries you must be very careful with your hands. You 23 eat with your left hand. Arabs consider(认为) it very 24 manners eating with left hands.

Ⅳ. 阅读理解。(30分)

(A)

Most American children eat potatoes. But many children don’t know which part of the potato is the best for food. Take a knife and cut a slice of potato from the middle as thin as paper. Hold the slice of potato against the light and look at it. You will see that the potato has a skin, an outside rim(边缘) and inside part. The outside rim, which is right under the skin of the potato, is more valuable(有价值) than other parts. But people usually throw it away with the skin. Even the skin itself is better for food than the inside part. When eating a cooked potato, if you choose the inside and leave the outside, you are throwing away the best part of it. If you can’t eat the whole potato, you can eat the outside rim first and leave the inside.

( )26. How many parts does the potato have?

A. It has only one part, outside rim.

B. It has two parts, skin and outside rim.

C. It has three parts, a skin, an outside rim and inside part.

D. It has four parts, middle, skin, outside rim and an inside part.

( )27. What’s the best part of the potato?

A. Outside rim. B. Inside part. C. Middle. D. Skin.

( )28. What should you eat first if you can’t eat the whole potato?

A. Skin only. B. Inside part. C. Outside rim. D. Part of it.

( )29. In fact the skin is ____.

A. not good at all B. better than the inside part

C. better than the outside rim D. as good as the outside rim

( )30. What does this passage tell about potatoes?

A. How to cook them. B. How to plant them.

C. What is in the potatoes. D. How to eat them.

(B)

When you’re invited to have dinner in a foreigner’s home, please remember the followings.

At the table, when the hostess(女主人) picks up her napkin, you may pick up yours and put it on your legs.

If a servant(佣人) passes food around, he will pass the dish to you at your left hand so that you can easily serve yourself with your right hand. Never serve yourself while the dish is on your right. It is then the turn of your neighbour on the right.

Do not reach across the table to get something in front of someone. That is not polite. Ask him or her to pass it to you.

There are things in the middle of the table, such as bread, butter, and candies. You shouldn’t take any until the hostess tells the servant to pass them to you.

Do not leave your seat without saying anything. If you need to leave the table to go to the washroom or do something else, you should say “Excuse me for a moment, please. ”

根据短文内容，判断正(T)误(F)。

( )31. You should put your napkin on your legs before the hostess picks up hers.

( )32. The dish is passed to you on either side.

( )33. If the food is far from you, you shouldn’t stand up to serve yourself.

( )34. You may take any food at any time.

( )35. When you have to leave your seat, you need to say “Excuse me for a moment, please. ”

(C)

An important question about eating out is who pays for the meal. If a friend of yours asks you to have lunch with him, you may say something like this, “I’m afraid it’ll have to be someplace cheap, as I have very little money.” The other person may say, “OK, I’ll meet you at Mc Donald’s.”

This means that the two agree to go Dutch, that is, each person pays for himself. He may also says,“Oh, no, I want to take you to lunch at Smith’s.” This means the person wants to pay for you. If you feel friendly towards this person, you can go with him and you needn’t pay for the meal.

American customs about who pays for dates(约会) are almost the same as in other parts of the world. In the old days, American women wanted men to pay for all the meals. But today, a university girl or a woman in the business world will usually pay her own meal. So as you can see, it is a polite thing to make the question clear at the very beginning.

根据短文内容，完成下列各题。

36. 将文中第一个句子翻译成汉语。

_________________________________________________________________________

37. What’s the meaning of “go Dutch”? ( )

A. 去饭馆 B. 订餐 C. 就餐 D. 各自付款

38. In the old days ____ often paid for all the meals in America.

39. If you feel friendly to the person, _______________________________.

40. We’d better know who will pay for the meal ______________________.

八年级下学期英语学习计划

一、本期指导思想

面向全体学生，提高学生的人文素养，增强实践能力和创新精神。正确把握英语学科特点，积极倡导合作探究的学习方式。培养学生积极地情感态度和正确的人生价值观，提高学生综合素质为学生全面发展和终身发展奠定基础。

二、学生情况分析

八年级(11)班60人，八年级(12)班也是60人。刚升入八年级的学生的英语基础方面还很薄弱，经过上学期不懈努力，学生的基础知识得到了加强，学习态度也有所好转。但是学生整体的惰性还是很强，自觉性很差。由于各种因素的影响，学生发展参差不齐。有少数学生因为基础不够好，学习很吃力而自暴自弃，有的因此扰乱课堂次序，这给教学带来不少困难。

另外，学生在情感态度，学习策略方面还存在诸多需要进一步解决的问题。例如：很多学生不能明确学习英语的目的，没有真正认识到学习英语的目的在于交流;有些同学在学习中缺乏小组合作意识;大多数同学没有养成良好的学习习惯，不能做好课前预习课后复习，学习没有计划性和策略性;不善于发现和总结语言规律，不注意知识的巩固和积累。

三、教材基本情况

《新目标英语》八年级(上册)，全书共有十二个单元，另两个复习单元。本教材各单元话题灵活，贴近生活实际。本册书将学习的一些语法知识点有：现在进行时、形容词和副词的比较级与最高级的用法、宾语从句、时间状语从句、条件状语从句、反意疑问句等。

四、教学总体目标

1、学生应有较明确的英语学习动机和积极主动的学习态度。

2、能听懂教师对有关熟悉话题的陈述并能参与讨论。

3、能读供七至八年级学生阅读的简单读物和报纸杂志，克服生词障碍，理解大意。

4、能根据阅读目的运用适当的阅读策略。

5、能与他人合作，解决问题并报告结果，共同完成学习任务。能在学习中互相帮助，克服困难。

6、能合理计划和安排学习任务，积极探索适合自己的学习方法。在学习和日常交际中能注意到中外文化的差异。

五、教学具体措施

1、每天背诵课文中的对话。要求学生背诵并默写，培养语感。

2、每天记5个生词，2个常用句子或习语。实施：利用“互测及教师抽查”及时检查，保证效果并坚持下去。

3、认真贯彻晨读制度：规定晨读内容，加强监督保证晨读效果。

4、坚持日测、周测、月测的形成性评价制度：对英语学习实行量化制度，每日、每周、每月都要给学生检验自己努力成果的机会，让进步的同学体会到成就感，让落后的`同学找出差距，感受压力。由此在班里形成浓厚的学习氛围，培养学生健康向上的人格和竞争意识。

5、对后进生进行专门辅导，布置单独的作业，让他们在小进步，小转变中体味学习的快乐，树立学习的自信，尽快成长起来。

6、关注学生的情感，营造宽松、民主、和谐的教学氛围。

7、实施"任务型"的教学途径，培养学生综合语言运用能力

8、在教学中根据目标并结合教学内容，创造性地设计贴近学生实际的教学活动，吸引和组织他们积极参与。学生通过思考、调查、讨论、交流和合作等方式，学习和使用英语，完成学习任务。

9、加强对学生学习策略的指导，为他们终身学习奠定基础。

10、要充分利用现代教育技术，利用计算机和多媒体教学软件，探索新的教学模式，开发英语教学资源，拓宽学生学习渠道，改进学生学习方式，提高教学效果。

总之，在实际教学活动中，需要不断摸索，以求收到更好的教学效果，不负家长和社会的厚望。
