W:You're looking well.By the way,Mike,did you hear about our team leader？ M:No.I just wonder why he didn't show up in the last im- portant game. W:He had such bad flu that they had to take him to the hospital. M:Oh,I didn't know that!And I'm sorry to hear that! W:Don't worry.He will be all right soon. Text 7 M:Ah,Mary,here you are at last!How was your journey? W:Terrible.The bus didn't move more than a few inches in half an hour.The traffic was so bad. M:Did you find out what had happened? W:Yes,there was an accident up ahead.Looked like two cars and a bicycle.There were a lot of police cars there. M:Was anybody hurt? W:I couldn't tell.I hope not.But the passengers on the bus were getting angry.One woman shouted at the driver. M:That was not fair.It wasn't his fault. W:I know.She should have got off and walked. Text 8 W:I am so bored of television these days.There's nothing good to watch. M:I totally agree.I miss watching football.But I don't agree with having to pay $25 a month to watch some. W:Yes,it is too much.I like watching cooking and music shows on TV.I used to have a Netflix account,but I didn't really use it. M:How much was that? W:I paid 10 per month. M:I heard there are some good series on there. W:There are a few,but I prefer watching movies. M:Talking about movies,I saw The Boss Baby 2 at the cin- ema last week. W:Oh,I wanted to see that.Was it as funny as the first? M:It was great.You should definitely check it out! W:Thanks,I will check to see if they're still showing it. Text 9 W:So what are you going to do this summer? M:I'm going to visit South America. W:Great! M:I'm going to be travelling around quite a lot and I'll probably spend three weeks there. W:So where are you going? M:To start off,I'm going to fly to Rio and perhaps I'll stay there for a few days. W:Do you know anyone there? M:No,but I've always wanted to go to Rio.It's quite a place of interest.And I'll probably go up the Sugar Loaf Mountain. ·17 录音原文 W:And where are you going after that? M:I'm going to fly to Santiago in Chile,where I've got some friends.We'll probably spend some time doing some sightseeing and then we're going to lie on the beach for a few days in valparaiso,which is on the coast,not far away from Santiago.Then I'm flying to Lima where I'm going to meet my girlfriend. W:Then you'll have a good time together. M:Yes.We'll probably go somewhere else.I don't know where yet,but I'd like to spend a week in the jungle. Then we'll probably fly home. W:Well,have a nice time! Text 10 First aid training is important-and the earlier you learn it,the better.As a doctor,I know that not only does first aid training help others,but it also improves young people's confidence and willingness to act in time of a danger- ous situation.You're never too young to start learning how to save a life.In an emergency,every second counts.Lack of confidence is the main reason why adults don't react.I hope this won't happen in the next generation.Our courses help children to learn first aid in a safe environment.Life is changeable-we never know what's around the corner.At any moment,someone could need our help.However,on- ly a third of British adults say they would attempt first aid. This may be why only 1 in 10 people survive an out-of-hos- pital heart attack.In countries where first aid is taught in schools,as many as 1 in 4 people survive.First aid is a skill a child can build on.It can even encourage young people into health care jobs.

Text 3 M:My back hurts.I'm going to take some medicine. W:I don't think you need any.Your back hurts because you've sat in front of the TV all day.You need to get some exercise. Text 4 M:Mum,I plan to go climbing on Friday. W:But the weather forecast says it will be rainy on that day.Saturday and Sunday will be sunny.

W:How about this Saturday,that is,the day after tomor- row?It will leave us two days to prepare food,drinks and stuff like that. M:Alright.What food should we provide? W:Well,I was going to make some delicious dishes,but now I think we can just prepare some barbecues and des- serts,so that people can help themselves.I think having everyone eat at a table is too formal and boring. M:Sounds interesting and practical.And we can bake a cake.Now,for the drinks,I'll go to the supermarket to get some beer and wine. W:And some fruit juice as well.Do we need any music? M:Of course.We can ask Paul and his band to give a per- formance. W:Great idea.I'll ring him right now. Text 9 M:Excuse me.Can you speak English? W:Yes.How can I help you?
