Eat Eastern foodD. See forests.BThe main difference between China and Western countries on the dinner table is chopsticks instead of a knife and fork, but that’s just a small difference. Besides, in decent(合宜的) restaurants, you can always ask for a pair of knife and fork, if you find the chopsticks not helpful enough.The real difference is that in the West, you have your own plate of food, while in China the dishes are placed on the table and everyone shares. If you are being treated to a formal（正式的）dinner and particularly if the host thinks you’re in the country for the first time, he will do his best to give you ataste of many different types of dishes. The meal usually begins with a set of at least four cold dishes, to be followed by the main courses of hot meat and vegetable dishes. Soup will then be served ( unless it is a Guangdong-style restaurant), followed by rice, noodles or dumplings. Perhaps one of the things that surprise a Western visitor most is that some of the Chinese hosts like to put food into the plates of their guests. In formal dinners, there are always “public”--chopsticks and spoons for this purpose, but some hosts may use their own chopsticks. This is a sign of real friendship and politeness. It is always polite to eat the food, If you do not eat it, just leave the food on the plate.People in China tend to over-order food, for they will find it embarrassing (尴尬）if all the food is consumed.( 吃光);When you have had enough , just say so, Or you will always overeat!（）71.

How to use Chopsticks.C.The Importance of Table Manners.D. Different Table Manners.CA greeting is a way of saying “ Hello “ to someone. People in different countries greet each other in different ways. 76_______________ In the United States , people usually shake hands.

Rooms will be cleaned every day. And the host is there to offer help and advice on your physical and mental health.Living areaHost families are mainly in Zones 2,3 and 4.

But It is very convenient to travel to the center of New York by subway.Meal PlansIt's important to know that few American families still provide a traditional cooked breakfast. Your breakfast mainly includes juice, bread and coffee. Cheese, fruit and cold meat or fish with vegetables followed by dessert, fruit and coffee.第2页共26页FriendsIf you wish to invite a friend to visit, you must ask your host for permission first, because some families feel uncomfortable when there are strangers in their homes.1.

English learners who want to live in American homesBBefore you hit ‘Enter’ on MSN, read this!It is often said that the language we use online is less formal(正式的) than that we use in a letter, or in direct speech sometimes. This is true, but it can also make us in trouble sometimes.The thing about online communication is that you have no idea what the person who is reading your messages is feeling. For this reason, it is always a good idea to be polite and careful when writing e-mails or messages to your第3页共26页friends.Chinese can be a direct language, but in English, people often talk about a subject in another way. So instead of saying “Please meet me here” or “Do this for me now”, English speakers usually go for indirect phrases like “Would it be possible”, “if you have time” or “It would mean a lot to me if…”If you have a close friend, you may still run into trouble because of your jokes. If you have asked someone to do something and they need a bit more time, you might joke with him: “What? You still haven’t done it yet? What’s wrong with you?” While this seems funny to you, your friend may feel unhappy.If you have foreign friends in different countries, the time difference can also be a factor. While you are waking up for class on Friday morning, they may be having a party on Friday night. You will be serious and they will, probably, be excited. So don’t be angry if they seem not to care about you. Just try to message them at the proper time.1. As a language, Chinese is ______, but English is not.A. politeB. rudeC. directD. formal2.

You’re having a great time when a phone rings at the table next to you. A man takes out his phone and starts talking loudly about problems he’s having with his girlfriend. He talks for almost ten minutes! This happens all the time－on buses, in restaurants, everywhere!Many people find cell phones useful in their daily lives. But we’ve all sat next to someone talking too loudly on a cell phone. You may want to tell the loudmouth to end the conversation, but let the management take care of those noisy customers. You can only control your own behavior. Here are a few rules:Off means off! Follow the rules of restaurants and other public places. If a sign says “turn off cell phones”, don’t use your phone. If you are allowed, speak softly and for a short time and try to move away form other people.Lights off, phone off! Never make calls in a theater or at the movies.Pay attention! Talking on a cell phone while driving is dangerous. And watch where you’re going when you’re walking down the streets and talking on the phone.As more people use cell phones, things are only going to get worse. So, the next time you’re getting ready to make a call, stop and consider the people around you.1.The man talking on the cell phone loudly in the restaurant will ________.A. make other customers angryB. pay more for his meal第5页共26页C. talk for half an hourD. be driven out by the boss2. Some people use cell phones in a rude way because____________.A. cell phones are common and available everywhereB. some public places allow them to do soC. they are proud of having cell phonesD. they don’t consider the people around them3. According to the passage, we shouldn’t make calls ___________.A. in restaurantsB. on busesC. at the moviesD. on the street4. From the passage we can infer(推断）that __________.A. cell phones have become the most useful tool in our lifeB. public manners play an important role in our lifeC. cell phones lead to people’s bad relationshipD. people ought to turn cell phones off in a public placesDThere's a saying, "When in Rome, do as the Romans do.”And when you eat Western food, do as the Westerners do.Here are some things you may wish to know about eating together in the West.Chopsticks are only used when people eat Chinese food. Knives and forks are used for most food. The fork is held in your left hand and the knife in your right, and the food is held with the fork and cut with the knife. Americans often cut all their food first, and then put the fork in their right hand to eat it. Soup is drunk with a spoon. However, there is some food which can be eaten with your fingers, such as chicken legs. seafood, bread and cake.At the start of a meal, ______________, you'll be invited to serve yourself ("Help yourself!"), or your plate will be filled by your host("Can I serve you?"). If you've been given something you don't like,it should be pushed to第6页共26页the edge of the plate and left. You don't have to say why, but if you feel an explanation is required, just say, "I'm sorry, I can't eat this." No one will be cross.If you're offered more food, but can't eat any more, just say, "No, thanks.It was delicious, but I've had enough."Generally, fewer dishes are prepared than in China. It isn't thought to be so important to offer too much food.Finally, it's sometimes difficult to know when the meal is over. If you've been invited to dinner by Western friends, You'll know that you're expected to stay and talk around the dinner table long after the last dish has been brought to the table, and it's thought quit rude if you leave as soon as you finish eating.The golden rule is: Watch the other people. Do as they do.1. What can we often use when we eat Western food?A. Knife and fork.B. Fork and chopsticks.C. Spoon and knife.D. Spoon and plate.2. What does the underline word “cross” mean in Paragraph 3?A. HappyB. ExcitedC. AngryD. Bored3. Which of the following can be put in the blank?A. Though you’re oldB. If you’re the hostC. If you’re the guestD. Though you’re young4. What’s the best title of he passage?A. Talking at the Start of a MealB. How to Live in Western CountriesC. Food that Foreigners EatD. Table manners in Western Countries三、词汇运用A、用方框中所给单词的适当形式填空，每词仅用一次。

一、选择题1．“物质的组成结构决定物质的性质，物质的性质决定物质的用途”。

下列有关物质的“组成结构﹣性质﹣用途”对应关系不一致的是（）物质组成、结构性质用途A稀有气体原子的最外层达到稳定结构化学性质稳定保护气B干冰分子间隔小，自身能量低升华吸热人工降雨C氢氧化钙能解离出氢氧根离子显碱性处理酸性污水D稀盐酸能解离出氯离子显酸性调节溶液酸碱度A．A B．B C．C D．D D解析：DA、稀有气体的原子的最外层达到稳定结构，所以稀有气体的化学性质稳定，可用作保护气，说法正确；B、干冰是二氧化碳的固体，干冰分子间隔小，自身能量低，所以干冰易升华吸热，可用于人工降雨，说法正确；C、氢氧化钙在水中能解离出氢氧根离子，所以显碱性，可用于处理酸性污水，说法正确；D、稀盐酸能解离出氢离子，所以显酸性，而不是因为电离出氯离子，可以调节溶液酸碱度，说法错误。

故选：D。

2．如图所示的图象能反映相对应实验的是（）A．①高温煅烧一定质量的石灰石B．②用相同质量、相同溶质质量分数的过氧化氢溶液分别制取氧气C．③向一定体积的稀盐酸中逐滴加入氢氧化钠溶液D．④某温度下，向一定量饱和硝酸钾溶液中加入硝酸钾晶体C解析：CA、石灰石分解后会生成氧化钙固体和二氧化碳，所以完全反应后会有固体存在，因此反应结束后固体的量不能是零，故选项A错误。

B、催化剂的作用只能是改变化学反应的速度，而不能改变生成物的质量，故用相同质量、相同溶质质量分数的过氧化氢溶液分别制取的氧气质量相同，图象反应生成的氧气量不等，故选项B错误。

C、盐酸溶液的pH小于7，起点小于7，氢氧化钠溶液的pH大于7，所以向一定体积的稀盐酸中逐滴加入氢氧化钠溶液时随着反应的进行溶液的pH不断变大，直至完全反应时溶液的pH=7，再滴加氢氧化钠溶液呈碱性pH大于7，反应过程与图象表示的一致，故选项C正确。

D、某温度下，向一定量饱和硝酸钾溶液中加入硝酸钾晶体，硝酸钾晶体不会继续溶解，所以溶液的溶质质量分数不会继续变大，故选项D错误。
