听力原文：Jeff (male): Hi Aref! Hi Marta!

Matra (female): Hi Jeff2.

Aref (male): Hi Jeff! Thanks for agreeing to help us with this university application form.

Jeff: No problem. It's the UCAS form, is it? Well, I brought mine along as well as an example. Let's have a look at the first page. ... Ah, here, you need to write in your addresses in your home countries.

Marta: Here? Where it says "home address"?

Jeff: That's right.

Marta: But we don't want them to send things to that address.

Jeff: They won't. See. It says they will send things to your residential Q21

address, which is in the UK.

Marta: Oh, I see!

Aref: And here we need to write the name of our school, don't we?

Jeff: Yes, and any other secondary schools you've attended. Don't forget to write "FT" in the box there on the right.

Aref: "FT" means "full-time", I suppose? Q22

Jeff: Yes, it does. Put the most recent school you've attended at the top.

Malta: Here it says we should enter our ethnic origin, but only if we are UK applicants.

Jeff: Well, you are living in the UK. Put it in anyway. It won't matter.

They only use it for statistical purposes. Q23

Aref: Should we put the subjects we've taken for A-level in this area—7A?

Jeff: No. That's for exams you've already taken and got the results

for. Here, underneath, in part 7B, you can see the space for Q24

exams that you've taken but don't have the results for, or are

going to take.

Malta: And do we need to write the name of our school there too?

That's where we will take the exams.

Jeff: That's right. Don't forget to put the address too.

Aref: Do you know the postcode for our school, Jeff?.

Jeff: Yes, it's PL3 6LY. Now, how about page 3? Q25

Marta: I did some part-time work. Should I put that in the employment section?

Jeff: Yes. I did some part-time work too. Write "PT" in the final box—for "part-time".

Marta: OK. And for "nature of work" I'll put "shop assistant". Q26

Jeff: OK. Now we've come to part 10—Personal Statement. Did

you write out a rough draft for me to look at, as I suggested? Q27

Marta: Yes, here's mine.

Aref: And here's mine.

Jeff: OK. Let me just have a quick look .... I'll just correct the

grammatical mistakes. There aren't many .... Be careful with

your spelling, Marta .... Aref, I wouldn't include this sentence

about wanting your parents to be proud of you. A personal

statement should be more practical, rather than an emotional Q28

appeal.

Aref: I see. It's a bit different in my culture. OK, I'll take your advice.

Jeff: I think that you both need to say why you're interested in those particular courses at those particular universities.

Marta: Well, I like some of the elective courses on offer in years two Q29

and three. That's how I chose those particular universities.

How about you, Aref?

Aref: Well, I considered that, but many of the law courses at university are very similar, so I also considered the geographical location of the universities.

Jeff: OK. Add those reasons. Have you both signed at the bottom of page 3? ... Yes, oh, Marta, you fo

If you start each day desperately wishing for an extra hour in bed, the following is likely to leave you feeling even more bad-tempered. Scientists have identified a "sleepless elite" — small group of people for whom a lie-in is a waste of time. Rather than being tired, bad-tempered under-achievers, they are an energetic, outgoing and optimistic group who can happily and healthily get by on just four or five shut-eye a night. If that were not irritating enough, they tend to be slim, able to hold down two jobs at the same time, and breeze through their extra-long days without needing caffeine pick-me-ups(咖啡因提神物)or cat naps. Working out how the gene cuts sleep without any obvious impact on health could help in the design of drugs us all a few extra hours in our day. The bad news is that while many of us get by on a few hours sleep a night, just one to three people in 100 qualify to be part of the sleepless elite. The research team is now appealing for members of the lucky group to come forward to allow their DNA to be studied. University of California researcher Ying-Hui Fu said: " My long term goal is to someday learn enough so we can manipulate the sleep pathways without damaging our health. Everybody can use more waking hours, even if you just watch movies. " Many of those who have already volunteered share fascinating characteristics. They are thinner than average, relentlessly upbeat(兴奋)and seem to have a high tolerance for physical pain and psychological set-backs. Researcher Dr. Christopher Jones told the Wall Street Journal: " Typically, at the end of a long-structured phone interview, they will admit they have been texting and surfing the Internet and doing cross-word puzzles at the same time, all on less than six hours of sleep. "

Which of the following could be the title of this passage?

A．The Sleepless Elite.

B．The Impact of Sleep on Health.

C．A New Research on Sleep.

D．Manipulation of Sleep Pathways.
