While it's easy enough to brush off a few sleepless nights with a pot of coffee and the occasional desk nap, you may be doing more harm than you realise. According to a new study from Surrey University, having less than six hours of sleep per night can actually shut down genes that play a key role in the body's 36 of self-repair.
We rely on our genes to constantly produce the proteins needed to 37 the wear on our bodies'tissue that we suffer throughout the day. But when scientists divided 26 volunteers into two groups—one of which slept for less than 6 hours per night for an entire week and the other for 10 hours per night—some of the sleep-deprived group's genes actually stopped working.
The functions of 711 genes in total were altered in some way, 38 ones involved in metabolism ( 新陈代谢), inflammation (炎症), immunity and stress. There is some good news though: a week of normal sleep was enough to 39 the malfunctioning genes back to peak condition, but should the40 sleep patterns continue, health problems that aren't, quite so easily reversible, like obesity (肥胖)and heart disease, have a 41 chance of cropping up. And this study only scratches the 42.
according to Professor Colin Smith, one of the scientists 43 in the study: This is only a week of sleep 44 and it is only five and a haft or six hours a night. Many people have that amount of sleep for weeks, months and maybe even years so we have no idea how much 45 it might be.

2、Questionsare based on the following passage.
In recent years, a growing body of research has shown that our appetite and food intake are influenced by a large number of factors besides our biological need for energy, including our eating environment and our perception of the food in front of us.
Studies have shown, for instance, that eating in front of the TV (or a similar distraction) can increase both hunger and the amount of food consumed. Even simple visual cues, like plate size and fighting, have been shown to affect portion size and consumption.
A new study suggested that our short-term memory also may play a role in appetite. Several hours after a meal, people's hunger levels were predicted not by how much they'd eaten but rather by how much food they'd seen in front of them in other words, how much they remembered eating..
This disparity (差异) suggests the memory of our previous meal may have a bigger influence on our appetite than the actual size of the meal. says Jeffrey M. Brunstrom, a professor of experimental psychology at the Univerity of Bristol.
"Hunger isn't controlled solely by the physical characteristics of a recent meal. We have identified an
independent role for memory for that meal,'" Brunstrom says. "This shows that the relation_ship between hunger and food intake is more complex than we thought. ""
These findings echo earlier research that suggests our perception of food can sometimes trick our body's response to the food itself. In a 2011 study, for instance, people who drank the same 380-calorie(卡路里) milkshake on two separate occasions produced different levels of hunger-related hormones (荷尔蒙), depending on whether the shake's label said it contained 620 or 140 calories. Moreover, the participants reported feeling more full when they thought they'd consumed a higher-calorie shake.
What does this mean for our eating habits? Although it hardly seems practical to trick ourselves into eating less. the new fmdings do highlight the benefits of focusing on our food and avoiding TV and multitasking while eating.
The so-called mindful-eating strategies can fight distractious and help us control our appetite,
Brunstrom says.
What is said to be a factor affecting our appetite and food intake?
A．How we perceive the food we eat.
B．what ingredients the food contains.
C．When we eat our meals.
D．How fast we eat our meals.
3、根据材料，回答问题。
Questions 19 to 21 are based on the passage you have just heard.
A．To show a videotape on survival in outer space.
B．To gain support for the space program.
C．To describe her experience on space missions.
D．To inform the audience about the space suit.
4、根据材料，回答问题。
Questions 9 to 11 are based on the conversation you have just heard.
A．She was invited only for the weekend.
B．The weather was too hot.
C．She had an appointment.
D．She had schoolwork to do.
5、回答题
B．Confused?It’s a vision of the world in 25 years，as dreamed up by today’s researchers in computer-human interaction(CHI)．
C． CHI normally means investigating better ways for people to interact with devices we have now,but last week attendees at the annual conference in Toront0，Canada，got ahead of themselves．They created an imaginary conference agenda for 2039 that predicts the kinds of challenges we will face with future computers--many of which will be implanted．
D．“It’s meant to be sort of the fringes(边缘)of human--computer interaction research，what’s really edgy or provocative，”says Eric Baumer of Cornell University in Ithaca，New York，who dreamed up the idea of the conference．“There’s a lot of retrospective thinking about the past，but there’s not as much thinking about what are the futures toward which we think we’re working．”
E．We used the abstracts to create a list of the questions we—or more accurately．our cyborg descendants--might have about computers in 2039．
Is it weird when my organs talk to each other?
F．In an abstract entitled“My liver and my kidney compared notes”，IBM researcher Michael Muller,based in Cambridge，Massachusetts，looks at what happens when the implanted monitors on people’s intemal organs—a network he calls Arterionet--are able to share data and pool knowledge to offer enhanced health tips．
G．His conclusion：“While most users were skeptical．many users proposed additional features that could lead to greater acceptance and compliance with such recommendations．”
H．It’s worth thinking about how people might deal with health tips from organ monitors．Wearable technology that tracks your activity or your health status is slowly gaining popularity while researchers earlier this year implanted power-generating silicone strips on the hearts，lungs and diaphragms(横膈膜) of live cows，pigs and sheep．Muller says the biggest challenge to creating Arterionet will be figuring out how to fit the artificial intelligence in a sufficiently small and safe package．
Why do plants need their own Facebook,again?
I．To understand this question，you need to know about Plantastic，the brainchild of Bill Tomlinson and his colleagues at the University of California at Irvine．
J．In their abstract，they reason that to make our food supply more sustainable，it may make sense to grow more fruits and vegetables close to home．But certain crops thrive when they’re grown in large quantities or alongside certain other plants--too tall all order for the average farmer．
K． Enter Plantastic，which would advise what plants would work best for your area and tell you what people in the neighbourhood are growing．Nanochips on plants would feed data back to the site．That information in turn could be used to 1earn more about what grows best in which environment．
L．Assuming people will want to know whether this adds anything，Tomlinson’s team created a fictional(虚构的)study that looks at l o backyard gardens over two growing seasons．It suggests that using Plantastic will increase yields by 4 to 12 percent．
M．Tomlinson’s graduate student Juliet Norton is working on an early version of what the online system might look like．
Autonomous cars have made driving so boring--what shall I do instead?
N．Andreas Riener at the Institute for Pervasive Computing in Linz．Austria，has written an abstract that starts with a bold view of the future：“The first self-driving car cruised on our roads in 2019．Now,20 years after,it is time to review how this innovation has changed our mobility behaviour．”
O． This vision is rooted in a real trend．Self-driving cars have been making headlines for several years now．They are legal to drive in the state of Nevada．and Google’s driverless car has already racked up hundreds of thousands of practice miles．
P． Reiner’s contribution is to explore how this will change us．He predicts that once the robots take the wheel everywhere．many of us will lose interest in driving altogether．Fewer of us will own our own cars．Those who do won’t waste as much time pimping them out or driving around iust for fun．People who still love cars might have to seek their thrills in special“recreation parks”．where they can drive manually in an artificial environment．“If the vehicles of the future are only a means to get from A to B，this car culture would get lost．”he says．
Did I just think up that idea or did an advertiser implant it?
Q．Multiple contributors to CHl 2039 ponder the future of brain implants．Whether it involves capturing input from each of our senses or recording neurons(神经元)directly in the brain，they assume that this one is a question not of if but when．And that could bring opportunities--and challenges．
R．Shachar Maidenbaum of the Hebrew University of Jerusalem，Israel，envisions devices that could record our day-to-day experiences and then allow US to share our memories with one another,revolutionising courts，classrooms，and our social interactions．
S．Daniel Gruen of IBM Research，meanwhile，envisions devices that could prompt your memory when you forget something．一with some darker consequences．“Imagine in the future that you have systems that help you with memory,”he says．“At what point do you start wondering．‘Wait．I’ve had an idea．Is that really mine or is that idea coming from somewhere else?”’
So，what is the ideal number of fingers?
T． Ever strain yourself swiping across your iPhone screen?That problem would go away if you could have an extra thumb surgically(手术地)attached to your hand．
U．That’s the starting point for a fictitious study of l 24 people who have chosen to augment their hands with bionic(仿生的)fingers--on average they have 13．4 digits．Johannes Schfnin9，a computer scientist at Hasselt University in Belgium，even comes to an intriguing conclusion：“The optimal finger count is l 2．5，with six normal—sized fingers on each hand and the dominant hand having an extra half-sized finger that can be moved with 6 degrees of freedom．”
V．It’s entertaining stuff but even SchSning admits that 25 years might not be long enough for this one to appear．
In his article．Michael Muller investigates the consequences of Arterionet’s being capable of sharing information to supply extra strong health advices．
