Many people love travelling to different countries, but if you plan to go abroad, you should know how to behave in different situations around the world.
Most travellers enjoy meeting new people, but sometimes you can be rude without saying anything. In Russia, you should never shake hands in a doorway, and if you're travelling in Thailand, never touch people's heads or point your feet at people. When the Japanese meet new people, they like giving business cards—but you should read the card carefully, not just put it in your pocket.
In most countries in Europe, people expect a lot of eye contact when you talk to them, but in many Asian countries, a lot of eye contact seems unfriendly. And in South America, people usually stand quite close to each other when they talk, but in countries like the USA, you need to give people more personal space. Also, it's rude to interrupt Japanese people while they are talking to you. You must wait until they finish before you start speaking.
In restaurants in China, you can leave a bit of food on your plate. It's OK to start smoking before other people finish eating, which you mustn't do in the UK. When in India, remember to eat with your right hand. Also avoid leaving empty bottles on the dinner table in Russia—that's bad luck.
When you're travelling in Asia, if someone invites you to his or her home, don't forget to take off your shoes when you arrive. And if you visit an Arab family's home, don't admire anything valuable because your host will feel he should give it to you as a present.
With so much to think about, it's not surprising that many people prefer going on holiday in their own countries—or you might just decide to stay at home!
1.Which of the following statements is TRUE?
A.We can admire anything valuable in an Arab family's home.
B.In China, people cannot smoke before other people finish eating.

D.In the USA, people usually stand quite close to each other when they talk.
2.What will the people in the USA feel when someone stand close to them when talking?
A.Unfriendly B.Friendly.
C.Happy. D.Polite.
3.What does the underlined word “interrupt” mean in Chinese?
A.跟随 B.打断 C.附和 D.强调
4.What is the correct order of the title from Paragraph 2 to Paragraph 5?
a. Eating out
b. In the home
c. Body language
d. Face to face communication
A.bcda B.dabc C.cdab D.abcd
5.What's the best title for the text?
A.Culture shock B.Table manners
C.Public rules D.Travelling plans

小杨在实验室做酸碱盐的性质实验时发现,一瓶标注氢氧化钠溶液的试剂瓶是敞口放置的。为了检验这瓶氢氧化钠溶液是否变质,小杨与同组的另两位同学共同探究:
(1)他们依据所学的化学知识,对这瓶溶液的成分作了如下猜想:
猜想一:可能是NaOH溶液;
猜想二:可能是Na2CO3溶液,作出此猜想的理由是__________;
猜想三:可能是__________。
(2)查阅资料得知:Na2CO3溶液能使酚酞溶液变红,CaCl2溶液、BaCl2溶液呈中性。为了验证溶液中是否含有Na2CO3,三位同学各取少量待测试剂于小试管中,分别滴加①酚酞溶液、②稀盐酸、③澄清石灰水,并依据产生的实验现象得出相同结论:溶液中一定含有Na2CO3。你认为他们所选试剂正确的是________(填字母代号)。
A ①②③ B ①② C ②③ D ①
(3)为了验证“猜想二”正确还是“猜想三”正确,他们又做了以下实验:①取少量待测试剂于试管中,滴加足量____溶液,溶液变浑浊;②过滤;③在滤液中滴加酚酞溶液,变红,所以____(填“猜想二”或“猜想三”)正确。如果在已经变红的溶液中逐滴加入稀盐酸,观察到的实验现象是___________________。
