We have received the order that we _______ not use the lab for a couple of days.

听力原文：W: Hi, John. Nice to meet you.

M: Hi. You are...?

W: I'm Mary. Don't you remember me? Your younger sister Susan is my good friend. I used to go to your home when you were still home.

M: Yeah, yeah. I remember, Mary, the active girl usually in red. Nice to meet you, too.

W: Susan told me I might meet you here, but I didn't expect it so soon.

M: When did you come here?

W: A couple of days ago. I've just been here for no longer than a week. Today I just had my first class.

M: How was your first class?

W: Well, I got lost and I was totally late!

M: Don't worry about it. It was a freshman class, so I'm sure that you weren't the only person who was late!

W: Yeah, the class was moved to another building, so I was late. But I don't think I missed much though.

M: Yeah, the first day is just going over the syllabus and finding out what will be expected of the students. Still, if you don't want to sit in the front, you'd better go there early to find a seat since the classroom usually fills up.

W: Thank you for telling me. Where are you going?

M: I have an appointment with my advisor. He is going to be mad at me because I am behind in my research for the fellowship! I'm supposed to have an outline ready by today!

W: Uh oh! What are you going to do?

M: I'll promise him a complete outline early next week. Luckily, I know something about this subject already, so I can whip together a short outline after biology class. That reminds me. I've got to run. See you later!

W: OK. Good luck!

M: Ah, yes, I'll call you later when I'm free. What's your phone number?

W: 555-8888, easy to remember. Hurry up! Bye!

A．Fellow students.

B．Former classmates.

C．Relatives.

D．Friends.

听力原文：M: Have you done the lab for physiology yet -- the one on taste?

W: Yeah, it was kind of fun -- mapping the taste buds. Didn't you think so?

M: I'm doing it this afternoon. How long will it take?

W: It went pretty quickly -- under an hour, anyway. See first you mix up the four solutions.

M: You take water and add either sugar, lemon juice, salt, or -- oh -- What was it?

W: Bitter quinine.

M: That’s it -- oh -- then what?

W: Then all you have to do is taste each sample and describe where each flavor seems most intense.

M: Is that hard?

W: Not really. One thing to remember though -- not all the taste buds are on the tongue.

M: Right. I’ll keep that in mind. And thanks for going over this with me. Maybe we could talk about this after I' ve tried it -- we could get a pizza or something.

W: Great. Give me a call.

What is the main purpose of the lab experiment?

A．To see how certain chemicals produce different flavors.

B．To determine if a person can distinguish salty and sweet solutions.

C．To map the location of taste buds.

D．To count the number of taste buds.

Almost Human?

Scientists are racing to build the world's first thinking robot. This is not science fiction: some say they will have made it by the year 2020. Carol Packer reports.

Machines that walk, speak and feel are no longer science fiction. Kismet is the name of an android (机器人) which scientists have built at the Massachusetts Institute of Technology (MIT). Kismet is different from the traditional robot because it can show human emotions. Its eyes, ears and lips move to-show when it feels happy, sad or bored. Kismet is one of the first of a new generation of androids -- robots that look like human beings -- which can imitate human feelings. Cog, another android invented by the MIT, imitates the action of a mother. However, scientists admit that so far Cog has the mental ability of a two-year-old.

The optimists (乐观主义者) say that by the year 2020 we will have created humanoids (机器人) with brains similar to those of an adult human being. These robots will be designed to look like people to make them more attractive and easier to sell to the public. What kind of jobs will they do? In the future, robots like Robonaut, a humanoid invented by NASA, will be doing dangerous jobs, like repairing space stations. They will also be doing more and more of the household work for us. In Japan, scientists are designing androids that will entertain us by dancing and playing the piano.

Some people worry about what the future holds: will robots become monsters (怪物)? Will people themselves become increasingly like robots? Experts predict that more and more people will be wearing micro-computers, connected to the Internet in the future. People will have micro-chips in various parts of their body, which will connect them to a wide variety of gadgets (小装置). Perhaps we should not exaggerate (夸大) the importance of technology, but one wonders whether, in years to come, we will still be falling in love, and whether we will still feel pain. Who knows?

Kismet is different from traditional robots because

A．it thinks for itself.

B．it is not like science fiction.

C．it can look after two-year-olds.

D．it seems to have human feelings.
