18．Are you having difficulty falling asleep？Try drinking a glass of warm milk．If that doesn't work，listen to soft，beautiful music．Still no luck？Try thinking about sheep jumping over a fence．If you are still awake，take a sleeping pill．But people who take pills often become dependent on the drugs．So you lie awake knowing that the new workday will soon arrive．If you have been in such condition for at least one month，you may have primary insomnia（失眠症）．A new study has found that you might fall asleep more quickly and stay asleep longer if you try"cerebral hypothermia"．It is not a complex medical process．It just means cooling down your brain．Eric Nofzinger and Daniel Buysse from the University of Pittsburgh Medical School led the study．They examined twelve people who had sleeping problems．Twelve others had no sleep problems．Each of them wore a soft plastic cap on their head at bedtime．
The caps had tubes inside filled with water．The researchers moved the water through the tubes and then changed the temperature of the water．Other studies showed that people who had sleeping problems often had more chemical reactions in the front of their brain．The researchers thought cooling down the brain might help．
On the first two nights of testing，the patients wore caps with no water．On the next two nights，the caps were worn，but the water was not cooled．Then the researchers cooled the water a little for another two nights．On the final two nights of the study，the temperature of the water was made much cooler．
The researchers found that the water caps didn't help the patients until the temperature was about 14℃．Most of the patients fell asleep faster and slept better when the coolest water was moving around their heads．
Dr Nofzinger and Dr Buysse noted that this was only the beginning of the brain temperature study．But they believed they had discovered something important that needed more research．
36．The first paragraph is written toB．
A．explain how serious insomnia is
B．bring forward the topic of the passage

A．increasing chemical reactions in the front of their brain
B．making them feel safe with a cap on their head
C．asking them to drink water to cool down
D．lowering the temperature of their brain
39．Dr Nofzinger and Dr Buysse seemed to believe thatB．
A．their research wouldn't help people greatly
B．more studies would be needed for their research
C．cooling down people's brain might be harmful
D．the results of their study would be made use of soon．

3．It's finally that time：the start of the college year．For some，this is the first year．For me，it's the last．But I still remember that summer between high school and college when I didn't really know what I was getting myself into．There are plans and ideas about what my college experience was going to be like，but none of them worked out as planned．Here are three things I wish I had known before my freshman year．
（1）Use the mental health services available to you．you aren't alone．
That first night at college was memorable．I was scared and in a new place．There was homesickness that got better as I settled in．and though I continued to miss things from home，these weren't the only reasons I felt down．The academic pressure to succeed and the social pressure to fit in are too much for some people．And these pressures don't just happen in freshman year．
For me，there were upsets long after the days that required a map to figure out where all the buildings were on campus．Close friends guided me in the right direction，which was important because talking helps---even if it's just with a friend．Don't be afraid to take that extra step．
（2）It's OK to change your mind about your major（专业）．
I entered the fall of my freshman year ready to major in politics，philosophy and economics，in preparation for a law degree．Things changed．You meet new people and discover new interests．
It's normal to be a little unsure of your plans once you start taking classes．So，don't worry if you haven't figured out exactly what you're going to major in．it will likely change anyway．
（3）You're there to get a degree and later a job，but a little fun won't hurt．
When my college days are long gone，I'm not going to remember the grades I got on papers or the late nights spent studying．
Instead，memorable moments will include playing video games with my roommate at 3：00am instead of writing a paper，or late-night runs with my friends after a night out---things that make for lifelong memories．
Doing well is important inside the classroom，but there are also jobs，internships（实习）and other pressures．Employers weigh internships and employment during college more heavily than your GPA，according to a 2012survey of employers by The Chronicle of Higher Education Finding a balance of killing it in the classroom，getting internships and having fun with friends is important．You don't want to burn out early．
Everyone says that college is the best four years of your life．but it can also be a stressful，messy period of self-exploration and discovery．But is it fun？No question．
