W：No, on Channel 5. It was about a couple who hitchhiked across the Sahara Desert.

M：No, I didn’t. Was it any good?

W：Well, it was quite good, I suppose, but all those miles of sand did get a bit boring after a while. I

       think I prefer horror films to travel stories and love stories.

M：I went out for a meal with my friends. They took me to a Greek restaurant.

W：Sounds unusual! What was the food like?

M：Actually, I quite liked it.

W：I’m not keen on foreign food myself. I’d rather stick to roast beef or just fish and chips.

M：Yes, I notice you always eat chips! Don’t you ever get sick of chips?

W：No, never. In fact, I’d rather eat chips than bread.

M：Well, I prefer trying new food to eating the same old things day after day.

Here is the 6 o’clock news.

       Police arrested a 27-year-old man in Hamilton this morning in connection with the National Bank robbery last Friday. The man was stopped by police after a car salesman told them that a man with a large quantity of cash was trying to buy a car. The National bank was robbed last Friday when an armed man entered and made off with about ten thousand dollars in cash.

       Scientists in Adelaide last week tested a new electric car that they say can reach speeds of up to 100 kilometers an hour. The car is driven by two rechargeable batteries that last for about 500 kilometers. Scientists at the State Automotive Research Institute in Adelaide believe that this is the most economical electric car so far invented.

       Bad weather closed the Desert Road for five hours yesterday. Many people were trapped in their cars in freezing conditions. Heavy snow continues to fall, and the High-ways department advises motorists to use chains if traveling on the Desert Road.

       That brings us to the weather forecast, for tonight and tomorrow. A belt of bad weather

W：Yes. A young girl. There were two of them. They were about 18. One of them asked me the way

       to the nearest MTR station. I pointed it out to her.

M：What did the other girl do?

W：The other girl moved quietly behind me. Then they both thanked me and started walking

       towards the MTR station. I carried on walking, but I suddenly realised that my bag was gone.

M：What did you do when you realised your bag was missing?

W：I turned round and saw the two girls running into the MTR station. One of them was carrying

       my bag.

W：Did you see the late night film on television yesterday?

M：The one on Channel 8?

M：Hello, Mary, this is John Smith from the bank. Is Paul there?

W：Not yet, John. He phoned me from the office 5 minutes ago today that he was going to look for

       a birthday present on his way home.

M：Hi, I’m thinking of taking a trip during the Christmas holidays.

W：Where would you like to go?

M：Well, maybe somewhere warm and sunny.

W：How about a tour to Southeast Asia?

M：Holly, is it possible to borrow your notes? I’ll return them tomorrow.

W：Sorry, but I usually review them. Say, how about copying them over in the library?

M：Okay. You’re a lifesaver, Holly!

W：No problem. But I don’t understand why you need my notes, Johnson; you haven’t missed any

       classes.

M：Weekday mornings, I’m a cashier at a coffee shop downtown. After work, I come directly to

       school!

W：Wow, you’re probably tired out!

M：That’s exactly why I want to borrow your notes. I’ve been sleeping during class, so my notes

       aren’t very good.

W：Well, here’s Professor Labelle. How are you feeling?

M：I’m usually awake at the beginning. But thirty minutes into class, I’m having trouble keeping

       my eyes open.

   （Text 7）

W：Sorry. I’m late, Tom.

M：That’s all right, Rita. Where have you been?

W：To the police station. I’ve lost my handbag. Or perhaps someone’s taken it. I don’t know.

M：Oh, no. What happened? Sit down. Is there anything important in it?

W：Very important! My check book, all the papers I need for work.

M：Oh, that’s terrible. But how did you lose it?

W：Well, as you know, I was with a friend all morning and we had lunch together. After I had

       lunch, I went shopping. And when I wanted to buy the shoes, I couldn’t find my check book.

       Then I remembered that it was in my handbag. And my handbag was in my car.

M：So you went back to your car?

W：But I didn’t find it there.

M：And you went to the police station?

W：Not immediately. Before I went to the police station, I called my friend’s office. No luck.

M：You should go to the restaurant where you had lunch and look for it.

W：Oh, I should have done that.

M：Now you’d better telephone the manager right away.

   （Text 8）

M：May I ask you some questions?

W：Yes, of course, Sir.

M：Where had you been earlier in the evening, madam?

W：I had been to a restaurant in Rolando with some friends.

M：What time did you leave the restaurant?

W：It was about 10：30, I suppose. My friends took the MTR and I began walking to the bus stop.

       I’d just reached the corner of Queen’s Road Central when someone tapped me on my right

       shoulder.

M：Someone tapped you on the shoulder?

Building a Good Teacher-student Relationship

      A good teacher- student relationship is one of the guarantees for successful teaching and learning. A good relationship leads to fruitful cooperation, that is, the teacher can guide his/her students more effectively and the students can learn more efficiently.

      From my personal experience I conclude that an ideal teacher- student relationship depends on the common efforts. For example, we have developed a warm, friendly relationship with our English teacher. We admire her for the special efforts she poured into our class. Her lectures are always well prepared and delivered clearly. We also admire the fact that she spends time generously with us students after class. Inspired by her devotion, we study all the more diligently.

      Of course, misunderstanding may occur once in a while. In this case, I think, both sides should be kind, patient and frank. By sitting down and having a good talk we can work out any trouble.
