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 noiseeven 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 you don’t have much experience of making phone calls in English, making a business call can be a worrying experience. Most business people, unless they feel very confident, prepare for an important phone call in a foreign language by making notes in advance. And during the call they make notes while they’re talking to help them to remember what was said. Although it’s quick and convenient to phone someone to give them information or to ask questions, the disadvantage is that there is nothing in writing to help you to remember what was said. It’s essential to make notes and often when an agreement is reached on the phone, one of the speakers will send a fax or e-mail to confirm the main points that were made. Because it’s so easy to be misunderstood when talking on the phone, it’s a good idea to repeat any important information (especially numbers and names) back to the other person to make sure you’ve got it right. Always make sure you know the name of the person you’re talking to. If necessary, ask them to spell it out to you, so that you can make sure you’ve got it right----and try to use their name during the call. And make sure that they know your name too.1. If you don’t have much experience of making phone calls in English, making a business call can be ().A.an easy thingB.a happy experienceC.a painful thing2.Most business people prepare for an important phone call in a foreign language by making notes in advance because ().A.they are very carefulB.their foreign language isn’t so goodC.they don’t want to miss any important information3.

Passage TwoTelephone books in the United States have white, blue and yellow pages. The white pages list people with phones by last name, the blue pages contain numbers of city services, government agencies and public schools. Businesses and professional (专业的) services are listed in a special section, the yellow pages. To make a long-distance call, you need an area code. Each area in the U. S. has an area code. The area covered by one area code may be small or large. For example, New York City has one area code, but so does the whole state of Oregon. If you want to know the area code of a place, you can look it up in the area code map, which is printed in the front of the white pages.There are a lot of publlic telephones in the US. They have their own numbers. If you are making a long-distance call on a pubic telephone and run out of money, give the number on you phone to the person you are talking to, then hang up the receiver, and he can call you back. If you make a long-distance call and get a wrong number, call the operator and explain what happened. This means that you can make the call again to the right number without having to pay more money.36. Where can you find the telephone number of a city council (市议会) in the telephone book?A. In the blue pages.B. In the white pages.C. In the yellow pages.D. In a special section.

Drop small branches as you walk so that you can find your way back.The most important thing to do when you are lost-stay in one place.( )16. If you get lost in the forests,you should walk everywhere to find your friends as soon as possible.

Recent research indicates that the mobile phone is changing not only our culture,but our very bodies as well.First,Let's talk about culture.The difference between the mobile phone and its parent一the fixed-line phone,is that a mobile phone corresponds to a person,while a landline goes to a place.If you call my mobile,you get me.If you call my fixed-line phone,you get whoever answers it.This has several implications.The most common one,however,and perhaps the thing that has changed our culture forever,is the"meeting"influence.People no longer need to make firm plans about when and where to meet.Twenty years ago,a Friday night would need to be arranged in advance.You needed enough time to allow everyone to get from their place of work to the first meeting place.Now,however,a night out can be arranged on the run.It is no longer"see you there at 8", but"text me around 8 and we'll see where we all are".Texting changes people as well.In their paper,"Insights into the Social and Psychological Effects of SMS Text Messaging",two British researchers distinguished between two types of mobile phone users:the"talkers"and the"texters”一those who prefer voice to text message and those who prefer text message to voice.They found that the mobile phone's individuality and privacy gave texters the ability to express a whole new outer personality.Texters were likely to report that their family would be surprised if they were to read their texts.This suggests that texting allowed texters to present a self-image that differed from the one familiar to those who knew them well.Another scientist wrote of the changes that mobiles have brought to body language.There are two kinds that people use while speaking on the phone.There is the"speakeasy":the head is held high,in a self-confident way,chatting away.And there is the"spacemaker":these people focus on themselves and keep out other people.Who can blame them?Phone meetings get cancelled or reformed and camera-phones intrude on people's privacy. So,it is understandable if your mobile makes you nervous.But perhaps you needn't worry so much.After all,it is good to talk.Through a person's texts,we can tell what personality he really has.A:Right B:Wrong C:Not mentioned

Five ways to make conversation with anyone Conversations are links,which means when you have a conversation with a new person a link gets formed and every conversation you have after that moment will strengthen the link.You meet new people every day:the grocery worker,the cab driver,new people at work or the security guard at the door.Simply starting a conversation with them will form a link.Here are five simple ways that you can make the first move and start a conversation with strangers.41.____________Suppose you are in a room with someone you don’t know and something within you says“I want to talk with this person”—this is something the mostly happens with all of us.You wanted to say something—the first word—but it just won’t come out.It feels like it is stuck somewhere,I know the feeling and here is my advice just get it out.Just think:that is the worst that could happen?They won’t talk with you?Well,they are not talking with you now!I truly believe that once you get that first word out everything else will just flow.So keep it simple:“Hi”,“Hey”or“Hello”—do the best you can to gather all of the enthusiasm and energy you can,put on a big smile and say“Hi”。42.____________It’s a problem all of us face:you have limited time with the person that you want to talk with and you want to make this talk memorable.Honestly,if we got stuck in the rut of“hi”,“hello”,“how are you?”and“what’s going on?”you will fail to give the initial jolt to the conversation that’s can make it so memorable.So don’t be afraid to ask more personal questions.Trust me,you’ll be surprised to see how much people are willing to share if you just ask.43.____________When you meet a person for the first time,make an effort to find the things which you and that person have in common so that you can build the conversation from that point.When you start conversation from there and then move outwards,you’ll find all of a sudden that the conversation becomes a lot easier.44.____________Imagine you are pouring your heart out to someone and they are just busy on their phone,and if you ask for their attention you get the response“I can multitask”.So when someone tries to communicate with you,just be in that communication wholeheartedly.Make eye contact,you can feel the conversation.45.____________You all came into a conversation where you first met the person,but after some time you may have met again and have forgotten their name.Isn’t that awkward!So remember the little details of the people you met or you talked with;perhaps the places they have been to the place they want to go,the things they like,the thing the hate—whatever you talk about.When you remember such thing you can automatically become investor in their wellbeing.So the feel a responsibility to you to keep that relationship going.That’s it.Five amazing ways that you can make conversation with almost anyone.Every person is a really good book to read,or to have a conversation with!45选?A.Just say itB.Be presentC.Pay a unique complimentD.Name,places,thingsE.Find the“me too”sF.Skip the small talkG.Ask for an opinion
