Mark,why do you want to learn Spanish? M:Well,I have always dreamt about visiting South Ameri- ca,and I really want to be able to make local friends.So I am learning to use it for traveling. W:That sounds excellent.Which countries will you visit? M:Peru,Argentina and Brazil. W:Oh,in Brazil people speak Portuguese.Are you aware of this? M:Yes,I know.I chose Spanish because I will spend most of my time in Argentina.Are Spanish and Portuguese similar? W:Not really,I'm afraid.But you will be able to pick up a few words,so Spanish would help you a little bit in Bra- zil. M:Oh,I'm happy to hear that. Text 9 W:Hey,Ben!Long time no see.Where are you going? You look so worried. M:Hello,Nancy.I'm going to the library.I am really worried about my exams.I have to prepare all three sub- jects in only 20 days. W:Why? M:I could not find time to prepare.Unlike you,I've been busy in my sports coaching. W:Oh!Are you kidding?Studies are our first thing.You should have managed time for your studies first. M:I'm so sorry.Can you give me some advice on time management? W:Well,the first thing is to set up a schedule for your dai- ly activities.Try to do all those in the designed time pe- riod. M:OK.I will try to do this. W:Also,give time to all activities according to their impor- tance.For example,your studies are your first thing now,so allow yourself more time for it.Cancel those of little importance.I mean first things first. M:Oh!Great idea.I hope I can do something to get through the exams. W:Good.Best of luck with your exams.I've got to go for my French class now. M:Thanks,Nancy.Goodbye. Text 10 Hello,my name is John Williams.I am an English teacher.And I have started a website to help you improve English listening and speaking skills as quickly as possible. My online English lessons take just five to ten minutes each day to complete.And there are no advertisements to take your attention away.You can also download the sound files to your computer and do exercises with them and take your ·17 lessons again any time.I have designed the online English course to be a very easy,cheap and quick way to improve your English speaking,listening and conversation skills, and also to improve your listening scores in English exams. Every day,you'll learn some new English vocabulary,idi- oms and phrasal verbs,and you'll feel more confident in working and making friends in English.My idea of learning English is that it is best for you to learn a little each day and remember it clearly.This idea doesn't mean a new method but instead it is a concept I hope you can accept.Whether you are taking other English classes or not,and no matter what method you use,I can help you to achieve your Eng- lish learning goals.
