1.W:I heard on the radio that the storm is coming.

　　M:If the weather man is as accurate as usual it will probably be sunny all day.

　　Q:What do we learn from the conversation?

　　2.W:Oh,dear,that will be $ 55 altogether.I don't have enough money.

　　I guess I have to put something back.

　　M:Wait a minute,Mary.I can lend you $ 20.

　　But with the money I lent you last night you owe me $ 30 now.

　　Q:How much did the woman borrow last night?

　　3.W:I really like those abstract paintings we saw in our art history today.What did you think?

　　M:I guess it's something I haven't acquired a taste for yet.

　　Q:What does the man mean?

　　4.W:I can't believe I still have this pain in my back.

　　This medicine the doctor gave me was supposed to make me feel better by now.

　　5.W:I've been working on this report all day.

　　And I've still got 10 pages to write.At this rate,I'll never get it done by tomorrow.

　　Q:What do we know about the woman?

　　6.M:Can you believe the way Mary was talking to her roommate?No wonder they don't get along.

　　Q:What can be inferred about the man?

　　9.M:I've noticed that you spend a lot of time tending to your garden.

　　Do you think you might like to join the university gardening club?

　　Q:What does the woman mean?

　　Passage One

　　Sugar is so much a part of our modern life that we only really think about it when,for some reason,we cannot obtain it.

　　It has been known to man for at least 3,000 years,but has come into common use only in modern times.

　　Until quite recently it was considered as a medicine and as a luxury for the very rich only.

　　Sugar is,then,very important to our civilization.

　　But what exactly is it?

　　Of course most of us recognize sugar immediataly as the sweet material which we put in coffee or cakes.

　　This common form of sugar is derived from two plants;the sugar cane and the sugar beet.

　　But there are in fact many types of sugar,and the chemist recognises hundreds of different varieties,each coming from a different source.

　　About 90% of the sugar is produced as food.

　　Only 10% is used in industry for purposes other than food production.

　　Yet sugar has great possibilities for use as the basis of chemicals.

　　It can even be used for making plastics.

　　In the future these potential uses will certainly be developed more than in the past.

　　Questions 11 to 13 are based on the passage you have just heard.

　　11.How long has sugar been used widely?

　　12.What material is mentioned that can be made from sugar?

　　13.Which of the following statements is true?
