W: How should we get along with the host family？ M: Always ask your host family questions when you don't completely understand something, or if you aren't sure that you have understood. Interact frequently with all members of the house- hold and keep good relations with them. Try something new whenever you can, e. g. , food, customs, activities, holiday celebrations, etc. W: If someone in my host family says something, either out of misunderstanding of or prejudice against my country, what should I do？ M: Don't be angry.

M: Actually, he was both highly intelligent and very rich. At first, Frida's father was against her marrying Diego because he was from an infamous family. But later on he agreed to it because he couldn't pay his daughter's medical expenses any more. Frida must have spent a fortune on doctors and operations over the years. W: Oh, yes, what a terrible life first polio and then that awful accident. It's amazing she produced so many paintings, isn't it？ M: Yes, she must have been an incredibly brave woman. W: But the marriage didn't work out too well, did it？ M: Well, it had its ups and downs. W: She painted this one with the cropped hair while they were separated, didn't she？ M: Yes, that's right. W. She really looked like a man here. In fact, she looked as if she's got a moustache! And why was she dressed in a man's suit？ I thought it might have had something to do with women's liberation. You know she cut off her hair to symbolize equality or something. M: Er, no the reason she cut off her hair and put on a man's suit is because Diego Rivera loved her long hair, and also loved the traditional women's Mexican dresses she used to wear. She did it to hurt him. (23) A．An actress. B．A writer. C．A teacher. D．A painter.

Rather than taking the final then, what they did was to find Professor Aldric after the final and explain to him why they missed the final. They told him that they went up to UVA for the weekend, and had planned to come back in time to study，but they had a flat tire (爆胎）on the way back and didn’t have a spare and couldn’t get help for a long time and so were late getting back to campus. Aldric thought this over and then agreed that they could make up the final on the following day. The two guys were overjoyed and relieved. So, they studied that night and went in the next day at the time that Aldric had told them. He placed them in separate rooms and handed each of them a test booklet and told them to begin.
