before waking up in virtually the same physical state they fell asleep in.
Now experts hope to develop methods of putting humans into a similar state which could help astronauts
survive long missions and lead to new ways of treating severely ill patients.
While many studies have examined hibernation in mice and hedgehogs, little research has been done into
the same condition in larger mammals such as bears.
But new research conducted at the Institute of Arctic Biology at the University of Alaska monitored the
animals" body temperature, heart rate and muscle movements while they slept.
The research results showed that during a five-month hibernation the bears" body temperatures varied
between 30~C and 36℃ in cycles that lasted between two and seven days-a pattern that was previously
unknown in hibernating animals.
The research project leader said, "If our research could help by showing how to reduce metabolic (新陈
代谢的) rates and oxygen demands in human tissues, one could possibly save severely ill patients. We simply
need to know how to turn things on and off to take advantage of the different levels of hibernations."
Craig Heller, of Stanford University, who contributed to the study, added, "There has always been a thought
that, if there is ever long-distance space travel, it would be good to be able to put people into a state of lower
metabolism or a state of hibernation. That"s almost science fiction but you can see the logical basis."

试题【阅读理解。 Alaskan black bears hibernate for up to seven months a year, during wh】；主要考察你对题材分类等知识点的理解。[详细]
举一反三
who"s just trying to be competent for day-to-day tasks.
1. Have a structure. 1_____ Your body should consist of paragraphs that are grouped according to
topic, each one dealing with a single element of your subject.
2. 2_____ When you say a car runs "fast", don"t leave it at that. Show me how fast it is by detailing
the vehicle"s top speed and acceleration, along with listing other cars it leaves in the dust. Do the same
with every other significant modifier (修饰语) you use.
3. Don"t pad words. 3_____ Most of the time, this ends up turning what"s essentially nice writing into
unreadable nonsense. You"ll see this with heavy use of unnecessary adjectives and adverbs, along with
useless phrases that can easily be cut off without losing meaning.
4. Choose good words. Sometimes, the way your text reads comes down to word choice. Don"t say
"converse" when you can say "speak"; don"t write "adjudicate" when you say "decide". 4_____
5. Use a writing software. Notice that we didn"t give any advice on grammar. That"s because using
a quality proofreading software can help you on that end. 5_____
B. Don"t let anything keep you from it!
C. Many inexperienced writers tend to pad words to meet word count goals.
D. Regardless of what you do, your writing should have an introduction and a conclusion.
E. Basically, put your words to good use and find words that will make the experience easier for your readers.
F. Some ideas can be quite correct.
G. Sure, a few mistakes might slip in now and then, but a good tool will take care of most of them.
transportation system. This is an unusual form of transportation, because it is a tunnel that trains travel through
and not an actual form of transportation.
The Chunnel is actually the English nickname for the Channel Tunnel. In French, it is called le tunnel sous
la Manche. It is a rail tunnel beneath the English Channel at the Straits of Dover. It connects Cheriton in Kent,
England with Sangatte in northern France. It is the second longest rail tunnel in the world.
Did you know that the British and the French had a race while they were building the Chunnel? The race
was to see who could get to the middle of the tunnel first. The British won by a little bit. It took 15 000 workers
over seven years to dig the tunnel. The tunnel was finished in 1994.
The completed Chunnel cost about $ 21 billion. But it all paid off, because it became very popular, very
quick. Millions of people use it. Now it is getting even more popular.
There are three complete tunnels in the Chunnel. The two outside ones are the passenger trains. The small
inner one is a guidance train. The guidance train is not used for transportation. Each track is exactly parallel to
each other.
There are four different train systems in the Chunnel. The Eurostar is a high speed passenger service that
connects London, Paris, Brussels, and Lille. The Eurotunnel shuttle is a rail ferry service. These shuttles carry
cars and vans. These are railcars that allow drivers to drive their vehicles on and off. There are also two
Eurotunnel goods service trains.
Now you know more about the Chunnel. Everybody off, this is the last stop.
B. Cheriton; Sangatte
C. Lille; Brussels
D. Dover; Kent
B. 
C. 
D. 
B. drivers and their vehicles
C. goods
D. staff members of the Chunnel
B. read in a magazine
C. broadcast on a train
D. heard in a railway station
psychology, defined psychology as"the science of mental life" and this definition provides a good starting
point for our understanding even today. We all have a mental life and therefore have some idea about what
this means, even though it can be studied in rats or monkeys as well as in people and the concept remains
difficult to understand.
Like most psychologists, William James was particularly interested in human psychology, which he
thought consisted of certain basic elements: thoughts and feelings, a physical world which exists in time
and space, and a way of knowing about these things. For each of us, this knowledge is primarily personal
and private" It comes from our own thoughts, feelings and experience of the world, and may or may not
be influenced by scientific facts about things. For this reason, it is easy for us to make judgments about
psychological matters using our own experience as a standard. We behave as amateur psychologists when
we offer opinions on complex psychological phenomena. However, problems arise when two people
understand these things differently. Formal psychology attempts to provide methods for deciding which
explanations are most likely to be correct, or for determining the circumstances under which each applies.
The work of psychologists helps us distinguish between inside information, which is subjective, and may
be prejudiced and unreliable, and the facts: between our predictions and what is"true" in scientific terms.
Psychology, as defined by William James, is about the mind or brain, but although psychologists do study
the brain, we do not understand nearly enough about its workings to be able to comprehend the part that it
plays in the experience and expression of our hopes, fears, and wishes, or in our behaviour during experiences
as varied as giving birth or watching a football match. Indeed, it is rarely possible to study the brain directly.
So, psychologists have discovered more by studying our behaviour, and by using their observations to obtain
hypotheses (假设) about what is going on inside us.
B. the definition of psychology
C. the complexity of psychology
D. the influence of psychology
B. of different thoughts and feelings about psychology
C. people usually make judgments based on their own ideas
D. amateur psychologists cannot use scientific terms
B. with their own experience
C. by observing how it works
D. by watching people"s behaviour
B. William James is considered to be the greatest psychologist in the 1890s.
C. Psychology suggests that living beings adapt to a changing environment so that they can survive.
D. It is important for psychologists, as well as ordinary people, to be aware of the reasons.
we really have eaten quite enough. Moreover, it finds, the caloric fallout of not paying attention to what
we"re eating doesn"t necessarily end when a meal is over.
Rose Cooper from England and her colleagues gathered 22 men and an equal number of women for an
experiment. Each person dined alone, continuously receiving nine small shares of food items. These ranged
from cheese twists and potato chips to carrots, cherry tomatoes and sandwiches or sausage rolls.
Because the goal was to test the potential impacts of distraction on fuUness, the researchers randomly
assigned half of the participants to eat in front of a computer-and to gain as many wins as possible at the
"card" game. Everyone else was told to focus on the sensory qualities of their meal.
According to their instructions, the participants ate all of the food given to them. Yet people who played
a computer game during lunch found their meal less filling than the mindful eaters had. Game players also
swallow clown twice as many cookies, almost an hour later, when they were allowed all the dessert they
wanted (in the name of a taste test). The British scientists present their findings in the February American
Journal of Clinical Nutrition.
The real question is why distracted eating should impact snacking. It appears, the scientists say, that
memory plays some tricky role in how we register what we eat and the degree to which it satisfies.
Interestingly, eight years ago, Britta Barkeling of Huddinge University in Stockholm and her colleagues
reported somewhat related findings. Their 18 overweight subjects had no choice other than to get rid of
everything but lunch, on one day-because they were blindfolded. Compared to a day when they could view
what they were dining on, these people consumed only three quarters as many calories. Yet even hours
afterward, they reported being no less full than on the day they had been able to see their plates.
Of course dining in the dark isn"t practical. And sometimes what we eat doesn"t really invite our absolute
attention. But there is certainly a growing mountain of data indicating that mindless eating is a waste of
resources, a risk to our waistlines-and a costly threat to health.
