Winter begins in the north on December 22nd. People and animals have been doing what they always do to prepare for the colder months. Squirrels (松鼠), for example, have been busy gathering nuts from trees. Well, scientists have been busy gathering information about what the squirrels do with the food they collect.
They examined differences between red squirrels and gray squirrels in the American state of Indiana. The scientists wanted to know how these differences could affect the growth of black walnut (黑胡桃) trees. The black walnut is the nut of choice for both kinds of squirrels. The black walnut tree is also a central part of some hardwood forests.
Rob Swihart of Purdue University did the study with Jake Goheen, a former Purdue student now at the University of New Mexico. The two researchers estimate that several times as many walnuts grow when gathered by gray squirrels as compared to red squirrels. Gray squirrels and red squirrels do not store nuts and seeds in the same way. Gray squirrels bury nuts one at a time in a number of places. But they seldom remember where they buried every nut. So some nuts remain in the ground. Conditions are right for them to develop and grow the following spring. Red squirrels, however, store large groups of nuts above ground. Professor Swihart calls “death traps for seeds”.
Gray squirrels are native to Indiana. But Professor Swihart says their numbers began to decrease as more forests were cut for agriculture. Red squirrels began to spread through the state during the past century.
The researchers say red squirrels are native to forests that stay green all year, unlike walnut trees. They say the cleaning of forest land for agriculture has helped red squirrels invade Indiana. Jake Goheen calls them a sign of an environmental problem more than a cause.
【小題1】The study done by Rob Swihart and Jake Goheen is to ________ .
A.find out the living conditions for squirrels |
B.do something to get rid of squirrels |
C.learn squirrels’ influence on black walnut trees |
D.save the forests in the American state of Indiana |

About 35 percent of British adults sleep with teddy bears. Many more share a bed with a partner or spouse. Others still co - sleep, alongside children in a family bed.
But lying with your iPad? A recent survey by marketing agency Rosette found that 68 percent of tablet owners use the device in the bedroom, more than in any other location. The living room took a close second place, at 63 percent, reports AdAge. com, and only 45 percent of respondents said they use their tablets on the go.
But bringing devices into the bedroom is a bad idea, if quality rest is your goal. One of the most important factors of sleepiness is darkness, which signals to the brain that it’s time to start speeding up production of the sleep - inducing hormone melatonin. But as the New York Times points out, in our modern world, we are exposed to light long after the sun sets. While any type of light can disturb your sleep, the blue wavelength light given off by cell phones, laptops, tablets and other gadgets is particularly troublesome. Research shows that this blue light causes alertness so decisively that it can actually be used to fight tiredness.
According to the National Sleep Foundation, 95 percent of Americans use some device, whether it’s a TV, laptop, cell phone or other products, within an hour of killing time. “Artificial light exposure between dusk and the time we go to bed at night push our sleeping sense to a later hour - making it more difficult to fall asleep,” said Charles Czeisler, Ph. D. , M. D. , chief of the division of sleep medicine at Brigham and Women’s Hospital in Boston.
Instead, experts recommend turning off all devices an hour before bedtime and finding another method for relaxation, like reading a book, taking a warm bath or performing a series of calming yoga poses. It’s also a good idea to exercise and lay off the caffeine several hours before bedtime.
【小題1】 According to a recent survey, most tablet owners use their iPad ________.
A.in the living room | B.in the bedroom |
C.in the office | D.on the move |
A.The light from cell phones is harmful |
B.Modern people have trouble falling asleep |
C.Darkness can create a good sleeping environment |
D.Blue light can prevent sleepiness decreasing |
A.dream of it | B.stay awake | C.feel sleepy | D.become tired |

Baekeland and Hartmann report that the " short sleepers" had been more or less average in their sleep needs until the men were in their teens. But at about age 15 0r so, the men voluntarily began cutting down their nightly sleep time because of pressures from school, work, and other activities. These men tended to regard their nightly periods of unconsciousness as bothersome interruptions in their daily routines.
In general, these "short sleepers" appeared ambitious, active, energetic and cheerful. They stuck to their opinions, and were very sure about their job choices..They often held several jobs at once, or worked full-or part-time while going to school. And many of them had a strong urge to appear "normal" or " acceptable" to their friends and colleagues.
When asked to remember their dreams, the " short sleepers" did poorly. More than this, they seemed to prefer not remembering. Similarly, their usual way of dealing with psychological problems was not to admit that the problem existed, and then to keep busy in the hope that the trouble would go away.
The sleep patterns of the " short sleepers" were similar to, but less extreme than, sleep patterns shown by many mental patients categorized as manic (躁狂者).
The "long sleepers" were quite different indeed. Baekeland and Hanmann report that these young men have been lengthy sleepers since childhood. They seemed to enjoy their sleep, protected it, and were quite concemed when sometimes they didn't have their desired 9 hours of nightly bed rest. They tended to remember their dreams much better than the " short sleepers". Many of the "long sleepers" were shy, anxious, quiet, nervous, passive, mildly depressed, and unsure of themselves ( particularly in social situations) . Several openly stated that sleep was an escape from their daily problems.
【小題1】From the passage, we can leam that .
A."short sleepers" need less sleep by nature |
B."long sleepers" sleep a longer period of time during the day |
C.many "long sleepers" preserve their sleeping habit formed during their childhood |
D.many " short sleepers" have to reduce their nightly sleep time because of busy work |
A.sleep is a good way to escape from the reality |
B.sleep is not so important as their daily activities |
C.sleep affects their judgment on some important things |
D.sleep is the best way to deal with psychological troubles |
A.do not know how to relax properly |
B.a(chǎn)re more unlikely to run into mental problems |
C.a(chǎn)re full of energy even under the pressures of life |
D.often pay little attention to the consequences of inadequate sleep |
A.a(chǎn)ppear disturbed | B.become energetic |

All too often, a choice that seems sustainable(可持續(xù)的)turns out on closer examination to be problematic. Probably the best example is the rush to produce ethanol(乙醇) for fuel from corn. Corn is a renewable resource —you can harvest it and grow more, almost limitlessly. So replacing gas with corn ethanol seems like a great idea.
One might get a bit more energy out of the ethanol than that used to make it, which could still make ethanol more sustainable than gas generally, but that’s not the end of the problem. Using corn to make ethanol means less corn is left to feed animals and people, which drives up the cost of food. That result leads to turning the fallow land –including, in some cases, rain forest in places such as Brazil—into farmland, which in turn gives off lots of carbon dioxide (CO) into the air. Finally, over many years, the energy benefit from burning ethanol would make up for the forest loss. But by then, climate change would have progressed so far that it might not help.
You cannot really declare any practice “sustainable” until you have done a complete life-cycle analysis of its environmental(環(huán)境的) costs. Even then, technology and public keep developing, and that development can lead to unforeseen and undesired results. The admirable goal of living sustainably requires plenty of thought on an ongoing basis.
【小題1】What might directly cause the loss of the forest according to the text?
A.The growing demand for energy to make ethanol |
B.The increasing carbon dioxide in the air |
C.The greater need for farmland |
D.The big change in weather. |
A.the energy benefit | B.the forest loss |
C.climate change | D.burning ethanol |
A.impractical | B.a(chǎn)cceptable | C.a(chǎn)dmirable | D.useless |
A.Technology | B.Sustainability |
C.Ethanol energy | D.Environmental protection |

As rain begins to fall from the clouds, it is very pure. However, as it falls through the air it dissolves some of the gases in the air ,It also collects bits of dust and microbes(微生物)that are floating in the air, When the rain reaches the ground it begins to pick up more dust and dirt, Many kinds of mineral substances dissolve in the water ,Sand and nud cannot dissolve in water.
Since water is so important to us, it is very important that the water we use should be clean , Otherwise, we might get some of the diseases that are carried by water Many microbes are harmful ,They are so small that we cannot see them ,These microbes must be removed or killed before the water is not clean, people who drink this water may get these diseases, Thus , to provide people with clean water, the government purifies the water.
Purification is a long process and consists of three stages: storing ,purifying and distributing ,The first stage is storing , Man-made lakes called reservoirs are used for this purpose ,Water from the rains ,other lakes, streams and rivers is collected in the reservoirs ,This water is usually dirty and muddy.
In the second stage shich is purifying , water from the reservoirs is filtered in a special pond, Stones, sand and other unwanted tiny things are caught in it, After that, tiny microbes are still present in the water ,These microbes are removed by “airing ”the water and by adding a chemical substance called chloring(氯)to the water ,This kills all the microbes in the water ,A fter this the water can be safely used for drinking.
The third stage is the distribution of the purified water to homes ,hospitals, offices ,factories and other places, This is done through a network of pipes of various sizes, These pipes must be make of a suitable material.

My house is made out of wood, glass and stone. It is also made out of software.
If you come to visit, you’ll probably be surprised when you come in. Someone will give you an electronic PIN (個人身份號碼)to wear. This PIN tells the house who and where you are. The house uses this information to give you what you need. When it’s dark outside, the PIN turns on the lights nearest you, and then turns them off as you walk away from them. Music moves with you too. If the house knows your favorite music, it plays it. The music seems to be everywhere, but in fact other people in the house hear different music or no music. If you get a telephone call, only the nearest telephone rings.
Of course, you are also able to tell the house if you want something. There is a home control console (控制臺), a small machine that turns things on and off around you.
The PIN and the console are new ideas, but they are in fact like many things we have today. If you want to go to a movie, you need a ticket. If I give you my car keys, you can use my car. The car works for you because you have the keys. My house works for you because you wear the PIN or hold the console.
I believe that ten years from now, most new homes will have the systems that I’ve put in my house. The systems will probably be even bigger and better than the ones I’ve put in today.
I like to try new ideas. I know that some of my ideas will work better than others. But I hope that one day I will stop thinking of these systems as new, and ask myself instead, “How will I live without them?”
【小題1】What does the passage mainly discuss?
A.How to develop a new system. | B.The function of the PIN. |
C.A home for the future. | D.Easy life in the future. |
A.To let readers know why his ideas are new. |
B.To let readers know how special his house is. |
C.To explain the importance of the PIN and the console. |
D.To explain more easily what the functions of the PIN and the console are. |
A.An IT expert. | B.A famous doctor. |
C.An idealist | D.An experienced teacher. |

I give two examples as to why intelligent life may not actually exist, though I admit that for me, or even for a physicist who devoted his or her entire life to researching and studying the universe, it's shocking to claim that completely no life exists elsewhere.
Keeping that in mind, I'd just like to consider conditions elsewhere in the known universe. You really only need to look at our own solar system or the Earth at certain periods in its own history to appreciate that most places are much worse and much less suitable for life than our mild, watery globe.
So far, space scientists have discovered about seventy planets outside the solar. But it appears that if you wish to have a planet suitable for life, you just have to be very lucky, and the more advanced the life is, the luckier you'll have to be. I'm by no means a space observer, but I can recognize some particularly fortunate breaks we've had on the Earth. For example:
We are, to a degree, at the right distance from the perfect type of star, the one that is big enough to radiate a huge amount of energy, but not so big as to bum itself out quickly. Had our sun been ten times as huge, it would have burnt out completely after only ten million years, instead of ten billion and surely we would not exist. Too near, everything on the Earth would have boiled and withered away; any further, everything would have frozen over.
The universe is a surprising place, and our existence within it is a wonder. If a long and unimaginably complex sequence of events dating back 4.6 billion years or so hadn't happened in a particular manner at a particular time --if, to take just one example, the dinosaurs hadn't been wiped out by a meteor(流星)--we might still be a few centimeters long, with whisker(胡須) and a tail, and you'll be reading this in a cave somewhere.
【小題1】What's the best title for this passage?
A.No Life Exists out of the Earth |
B.Seventy Planets Discovered |
C.A Place Full of Wonders |
D.Perfect Conditions for Life |
A.The Earth is the only planet that can receive energy from the sun. |
B.The sun is at the right distance from us and in proper size. |
C.The distance between the planets was neither too long nor too near. |
D.The dinosaurs were no longer a threat to the Earth. |
A.Exploded. | B.Expanded. | C.Floated away. | D.Dried and died. |
A.A history book. | B.A magazine. | C.A science fiction. | D.A famous novel. |
