题型:不详难度:来源:
Modern inventions have speeded up people"s lives amazingly. Motor cars cover a hundred miles in light more than an hour, aircraft cross the world inside a day, while computers operate at lightning speed. Indeed, this love of speed seems never ending. Every year motor cars are produced which go even faster and each new computer boasts(吹嘘) of saving precious seconds in handling tasks.
All this saves time, but at a price.When we lose or gain half a day in speeding across the world in an airplane, our bodies tell us so. We get the uncomfortable feeling known as jet lag;our bodies feel that they have been left behind in another time zone. Again, spending too long at computers results in painful wrists and fingers. Mobile phones also                   , according to some scientists;too much use may put harmful radiation into our brains, a consequence we do not like to think about.
However, what do we do with the time we have saved? Certainly not relax, or so it seems. We are so accustomed to constant activity that we find it difficult to sit and do nothing or even just one thing at a time. Perhaps the days are long gone when we might listen quietly to a story on the radio, letting imagination take us into another world.
There was a time when some people"s lives were devoted simply to the cultivation(耕耘) of the land or the care of cattle. No multi tasking there;their lives went on at a much gentler pace, and in a familiar pattern. There is much that we might envy about a way of life like this. Yet before we do so, we must think of the hard tasks our ancestors faced: they farmed with bare hands, often lived close to hunger, and had to make tools from wood and stone. Modern machinery has freed people from that primitive existence.
小题1:What"s the passage mainly about?(within 10 words)
                                                                       
小题2:List the difficulties our ancestors met according to the text.(within 15 words)
                                                                      
                                                                      
                                                                      
小题3:Fill in the blank in the 2nd paragraph with proper words or phrases.
                                                                       
小题4:Why do we make new products more and more time-saving according to Paragraph 1 of this passage?
                                                                       
小题5:Translate the underlined sentence in the 3rd paragraph into Chinese.

举一反三
Many people are aware of the beauty of a solar eclipse (日食), but are surprised to learn that lunar eclipses are often just as impressive. While total solar eclipse lasts only for a few minutes and can be seen only in a small area of a few kilometers, total lunar eclipse can last for several hours and can be seen over much of the planet. In fact, the beauty and stability of lunar eclipses make them a favorite of both amateur and professional photographers.
Lunar eclipses generally occur two or three times a year, and are possible only when the Moon is full. When we see the Moon, we are actually seeing sunlight reflected off the surface of the Moon When the Earth is positioned in between the Moon and the Sun, however, the Earth"s shadow falls on the Moon, and a lunar eclipse occurs.
The type of lunar eclipse - total, partial, or penumbral (半影) - that occurs depends both on how much of the Moon passes through the Earth"s shadow and through which part of the shadow it passes. A penumbral eclipse occurs when the Moon passes through the Earth"s outer shadow. This type of eclipse is brief and frequently goes unobserved by all but astronomers. By contrast, total and partial eclipses occur when all or part, respectively, of the Moon passes through the umbra(本影) shadow of the Earth. These eclipses are quite easy to see and are widely observed.
Unlike solar eclipses, lunar eclipses are safe to watch. Solar radiation that occurs during an eclipse of the Sun can cause a form of burns of one"s eyes known as eclipse blindness. In fact, the only way to safely view a solar eclipse is by using specially designed equipment. However, since the Moon"s light is reflected sunlight, it is completely safe to watch a lunar eclipse without any special equipment, although a pair of binoculars can certainly help the viewer appreciate the beauty of this phenomenon
小题1:The underlined word "stability " most probably means_______.
A.strengthB.positionC.steadinessD.visibility
小题2:According to the passage, a partial lunar eclipse occurs________.
A.when the Moon passes between the Sun and the Earth
B.when all of the Moon passes through the Earth"s umbra shadow
C.when only a part of the Moon passes through the Earth"s outer shadow
D.when only a part of the Moon passes through the Earth"s umbra shadow
小题3:The passage implies that penumbral eclipses are________.
A.longer-lasting than most solar eclipses
B.more common than partial or full lunar eclipse
C.the result of the shadow cast by the Moon onto the Earth
D.more difficult to observe than other types of lunar eclipse
小题4:According to the passage, it is safe to watch a lunar eclipse, unlike a solar eclipse, because ________.
A.moonlight is less strong than sunlight
B.a lunar eclipse is briefer than a solar eclipse
C.a lunar eclipse lasts much longer than a solar eclipse
D.special equipment can be employed to view a lunar eclipse

There has been a large increase in the number of natural disasters over the past few years, and it is believed that global warming and climate change could cause even more disasters in thefuture. Some of the world’s leading cities are facing disasters like floods and heat waves.
London
London’s flood defences are getting older. Since 1982, the Thames Barrier(水闸)has protected the city from the threat (威胁)of flooding, but it was only designed to last until 2030 and close once every two or three years. About 31 years later the barrier now closes five or six times a year and according to Environment Agency predictions, by 2050 the barrier will be closed on almost every tide if the problem is not solved
There are 26 underground stations, 400 schools, 16 hospitals, an airport and 80 billion worth of property(财产)in London’s flood risk area, so large scale flooding would be disastrous.
Paris
Over a six week period in July and August 2003, more than 1 1,400—mainly elderly people—died in France from dehydration(脱水)and extremely high body temperature in a deadly heat wave. Heat waves of similar intensity(强度)are expected every seven years by 2050, so what can be done to make sure such a disaster does not happen again?
One solution is to have air-conditioners installed(安装)in elderly care homes. But this is considered a short-term solution, as the increase in demand for electricity also increases carbon emissions(排放).
In Paris the local authorities are encouraging architects to design new types of buildings such as the building “Flower Tower,” which uses a covering of bamboo to act as a natural air-conditioner.
Shanghai
Shanghai is the fastest growing city on Earth. It has a population of 18 million and is only 4 meters above sea level. Sea levels are predicted to rise by 20 cm within the next century.
About 250,000 people move to Shanghai every year in search of work, placing extra demands on energy consumption(消耗). China depends heavily on coal—fired power stations, but these emissions increase temperatures and, in turn, warmer seas increase the risk of typhoons.
小题1:What problem should be settled now in London?
A.How to protect the city’s property
B.Where to build its flood defences
C.How to use the Thames Barrier to protect the city
D.How to improve the function of the old flood defences
小题2:Which of the following measures can’t solve the heat wave disaster in Paris?
A.Putting up new types of buildings with a covering of bamboo.
B.Having air-conditioners installed in elderly care homes.
C.Forbidding the city to build “Flower Tower”.
D.Encouraging architects to design new types of buildings.
小题3:The major threats to Shanghai are __________.
A.increasing population and coal-fired power stations
B.rising sea levels and typhoons
C.extremely high temperature and rising sea levels
D.extra demands on energy consumption and typhoons
小题4:The purpose of the passage is __________.
A.to tell us how to protect the big cities
B.to give advice on how to defend natural disasters
C.to explain what causes flood and heat waves
D.to warn us of the increasing natural disasters in big cities

What if I took that big jump on my bike?What’s the worst thing that could happen if I go out at midnight?Should try smoking?The teen years can play out like a choose-your-own-adventure novel.
Teenagers must act on an endless parade of choices.Some choices.including smoking.Come with serious consequences.As a result, adolescents often find themselves trapped between their impulsive tendencies(-Just try it!)and their newfound ability to make well-informed and logical choices(-Wait, maybe that’s not such a good idea!).
So what makes the teenager’s brain so complex? What drives adolescents-more than any other age group-to sometimes make rash or questionable decisions?
If you have ever thought that the choices teenagers make are all about exploring and pushing limits, you are on to something. Experts Experts believe that this tendency marks a necessary period in teen development.The process helps prepare teenagers to confront the world on their own. It is something all humans have evolved to experience-yes, teens everywhere go through this exploratory period.Nor is it unique to people:Even laboratory mice experience a similar stage during their development.
For example,laboratory experiments show that young mice stay close by their mothers for safety. As mice grow.their behavior does too.“When they reach puberty,they’re like,‘I’m gonna start checking out how this environment looks without my mom,…explains Beatriz Luna,of the University of Pittsburgh.
As a developmental cognitive neuroscientist,Luna studies those changes that occur in the brain as children develop into adults.She and other researchers are showing how the teen experience can lead to powerful advantages later in life.Take mice again:Young mice that explore most tend to live longest——that is,unless a cat eats them,Luna adds.

As people in Beijing and northern China struggle with severe air pollution this winter,the toxic(有毒的)air is also making life hard for plants and even food crops of China.
"in the last 50 years there has been a 1 6-fold increase in ozone(臭氧)pollution”in the Beijing area,said Hanqin Tian of Auburn University in Alabama,who studies the effects of China"s pollution and climate change on plants.
Ozone is particularly harmful to plants because it damages the pores(气孔)  on leaves,called stomata,which plants use to regulate how much water evaporates from the leaves.That,in turn,affectS how much water a plant must take up through its roots.Changes in water uptake by plants have been documented in other parts of the world,including the United States,as having major impacts on regional groundwater and surface water supplies.
In studies of the long-term productivity of plants,Hanqin Tian and some of his colleagues show that ozone pollution,along with climate change,has been lowering plant productivity in China,which reduces the amount of carbon and other pollutants that the plants Can absorb to fight all the emissions from the burning offossil fuels.
The worst effects on plants are likely to be in areas where the growing pollution problem is just fairly new, said Arthur Chappelka, also a plant researcher at Auburn University.Some plants are more resistant to pollutants than others,he said,and the plants that are living today in long-polluted urban areas are likely to be only those that are very pollution tolerant.
Away from the cities, however, where crops are necded to feed China’s yast population, the effeets of the growing pollution on crops is a significant concern.
“In some ways it affects the crop production and food securiy of China,”said Hanqin Tian.“Air quality is really important for human health, plants and ecosystem and sustainability.”
The problem is bound to get worse as China continues to develop economically, he said, and so he and other researchers continue to urge the Chinese government to take action to reduce emissions from cars and industries.
小题1:ozone does harm to plants mainly by ________.
A.exposing them to strong sunlight
B.damaging the structure of their leaves
C.adding more pores to the roots
D.making the land unfit for the plants to grow
小题2:Which of the following statement does Hanqin Tian support?
A.Ozone pollution has increased 1 6 times in the past 30 years.
B.Ozone pollution has lowered plant productivity alone.
C.Plants can take in a large amount of carbon and other pollutants.
D.The toxic air has few effects on food supply in China.
小题3:What Can we infer from the passage?   
A.Healthy foods are not available in Beijing.
B.Some kinds of plants aren’t affected by air pollution.
C.Crops in China are hard to feed its large population.
D.People should stop developing economically
小题4:According to the passage,the Chinese govemment should
A.care more about developing economy
B.reduce the number of cars and industries
C.continue to make more researches
D.take measures to reduce carbon emissions

People always say that the earlier one learns a language, the     it is to do so, in theory it is that,     , in my opinion, that refers to spoken language. Capability(能力) to practice some essential(基本的)     of a language and read between the lines can only be trained through proper reading ways and hard work     .So spending money to help      learn English may    up with disappointment. It is likely that the more you     ,the more you are let down.
The daughter of one of my friends     English in primary school,     her foreign teacher’s blindness     psychology. She did not want to go on     English until middle school,     a college student studying English slowly     her interest in the language.
It is better to have the child learn Chinese than to have some difficulty     learning English for several years. Having been engaged in English education,     find that despite(尽管) their excellent     , many students have     command of English words and phrases. So I suggest that children
   classical Chinese prose(散文),rather than     them to learn English hurriedly. Otherwise, they may let go the best time to    the language ability of their mother tongue.
