22. In the UK, in business situations, when you meet someone for the first time you shake hands and say, “How do you do”. This is not really a question, and the reply to it is another greeting such as “How do you do” or “Hello” or “I’m very pleased to meet you” or, if you have met the person sometime before, “It’s good to see you again”. You don’t shake hands every time you meet someone, you just greet them. If you are invited to someone’s house for dinner, it is usual to take a present– some chocolates or flowers or, if you know them quite well, a bottle of wine. If you do not know the host well, don’t be the last person to leave. Telephone the next day to thank the host for the meal. English people don’t like to talk about personal things, and tend to avoid religion, politics and money. Good topics for small talk are the weather, holidays, weekend activities, gardens and architecture, especially houses and homes. When you go to a pub or bar, it’s usual to take turns to buy a drink for everyone in your group and pay for the drinks when you get them from the bar and before you drink them. 1．The first paragraph tells us _________. A．when you meet someone for the first time, you should shake hands and say, “How do you do” B．what you usually do and say, when you meet an old friend C．how to greet someone in business situations 2．If you are invited to someone’s house for dinner, it’s better to _________.

23. The chances that you will be a victim of violent crime are low. But you can avoid risk in the following ways. AT HOME You should make sure your house or flat is secure. Always lock the door from the inside at night, but you must keep the key nearby, so that you can use it to get out quickly if there is a fire. You must never give keys to workmen as they can easily make copies. If you wake up and hear a burglar, stay quietly in bed. Pretend you are asleep. If you feel more confident, switch on the light and make a lot of noise; even if you are on your own you should call out loudly to an imaginary companion, so that the burglar thinks you are not alone and runs away. You should have a phone or a mobile in your bedroom to alert the police immediately. If you come home and think you see signs of a break-in, you shouldn’t go in, the burglar may be inside. You should go to a neighbour and call the police. ON THE STREET At night: Always walk facing the traffic, so that a car cannot pull up behind you. You mustn’t go through parks or woods. If you think someone is following you, cross the road one or two times. If he or she continues to follow you, go to a pub or other public place. Always carry your bag close to you, but carry your house keys in your pocket so that you can open the door quickly. If someone attacks you – remember your safety is more important than your property. 1．This passage mainly focuses on ________. A．how to avoid the crimes both at home and in the street B．what you should do at home if there is a burglary C．how to avoid the crime at night in the street 2．If you want to guarantee you are secure at home, you should _________. A．always lock the door and put the key in a secret place far away from the door B．never leave the keys to workmen since they can easily make copies C．keep silent all the time even if you are on your own when a burglar steals into your house 3．Based on the passage, if you notice someone following you, it’s better for you to _________. A．shout loudly B．go to public places C．run quickly 4．Why should you have a telephone in the bedroom A．Because we might use it to alert the burglary. B．Because it’s convenient for us to talk to our friends while lying on bed. C．Because it’s convenient for us to report to the police in case there is a burglary. 5．From the passage, we can infer that we might be victims if _________. A．we cannot part with the money when being attacked B．we don’t walk in the empty street C．we carry too much cash 提示：请将正确答案的序号（大写字母ABC）填写在空白处，系统自动判分 您的答案是：____ 2.____ 3.____ 4.____ 5.____
