Hummingbirds have got their name from the distinct “hum” sound made by their rapidly flapping (拍打) wings．The size of the bird decides the number of flaps it can do．The average lifetime of a hummingbird is 3 or 4 years, but some of them have lived beyond 12 years also．They are unique in many ways．Besides th
e number of rapid flaps they can do per second, they can also fly backwards.
Hummingbirds have an amazing sense of assessing the amount of sugar in the nectar (花蜜) they eat．They feed on the nectar of flowers．Hummingbirds do not feed on flowers whose nectar contains less than 10% sugar．Talk about a sweet tooth! As they cannot sustain themselves on nectar alone because of its poor nutritional value, they also feed on insects and spiders, and hummingbird food mixture that one can make at home.
Attracting hummingbirds to your garden will require a little planning．Plant butterfly bush, mimosa, coral bells, foxglove, morning glory, etc．These flowers attract the hummingbirds due to their high visibility (可见性) and nectar production．Avoid using pesticides (杀虫剂), as it will not only kill the insects around the flowers, but hurt the hummingbirds as well.
A common food for these birds is the sweettasting sugar syrup (糖浆)．Hummingbird food ingredients are just two: sugar and water．Take a large clean bowl, pour in it four cups of hot water, and dissolve one cup of table sugar in it．Stir slowly until all sugar has dissolved．
Hummingbirds, tiny as they are, collect a lot of nutrition．Providing them with hummingbird food mixture made of sugar water is a sure way to get all these beauties humming in your garden.Hummingbirds will have some little animals for their meal when .
| A．they can't find any green plants |
| B．they can't take in enough nutrition |
| C．they are bored with eating nectar |
| D．they are too old to fly |
In order to attract hummingbirds, you should .
| A．plan high trees |
| B．grow plants with small flowers |
| C．grow plants whose flowers are bright in color |
| D．grow plants coming into flower in the morning |
The main idea of the fourth paragraph is .

People all over the world today are beginning to hear and learn more and more about the problem of pollution. Pollution is caused either by man's release of completely new and often artificial substances into the environment, or by releasing greatly increased amounts of a natural substance , such as oil tankers into the sea．
The whole industrial process which makes many of the goods and machines we need and use in our daily lives, is bound to create a number of waste products which upset the environmental balance, or the ecological balance as it is also known. Many of these waste products can be prevented or disposed of sensibly, but clearly while more and more new and complex goods are produce there will be new, dangerous wastes to be disposed of, for example, the waste products from nuclear power stations. Many people, therefore, see pollution as only part of a larger and more complex problem, that is, the whole process of industrial production and consumption of goods. Others again see the problem mainly in connection with agriculture, where new methods are helping farmers grow more and more on their land to feed our ever-increasing populations. However, the land itself is gradually becoming worn out as it is being used in some cases, too heavily, and artificial fertilizer cannot restore the balance.
Whatever its underlying reasons, there is no doubt that much of the pollution caused could be controlled if only companies, individuals and governments would make more efforts. In the home there is an obvious need to control litter and waste. Food comes wrapped up three or four times in packages that all have to be disposed of; drinks are increasingly sold in bottles or tins which cannot be reused． This not only causes a litter problem, but also is a great waste of resources, in term of glass, metals and paper. Advertising has helped this process by persuading many of us not only to buy things we neither want nor need, but also to throw away much of what we do buy. Pollution and waste combine to be a problem everyone can help to solve by cutting out unnecessary buying ,excess consumption and careless disposal of the products we use in our daily lives.
45．The underlined phrase “disposed of ”in the second paragraph means_______.
A． dealt with B． exposed
C． disapproved of D． collected
46． In the writer’s view ,the more new goods, _______.
A． the less pollution
B． the harder pollution can be prevented
C． the more pollution there will be
D． the more easily pollution can be controlled
47．What can we learn from the last paragraph?
A． We can do much to reduce pollution.
B． The government is trying hard to stop pollution.
C． Individuals know how to get rid of the habit of littering everywhere.
D． We can’t stop buying unnecessary things.
48． People can help solve the problem of pollution by _______.
A． urging their governments to control litter and waste
B． making anti-pollution advertisements
C． cutting down the use of oil and other oil products
D． reducing unnecessary buying, over-consumption and careless disposal of wastes

A．
Each Indian tribe had a different language. Many Indians never learned any language except their own. Do you know how Indians from different tribes talked to each other? They had two ways to talk without sound． One way was by sign language; the other way by signals.
Sign language is a way of talking by using signs. Indians used sign language when they met strangers. In this way, they could find out whether the stranger was a friend or an enemy. In the Indian sign language, signs were made with the hands. One sign meant “man”. Another meant “horse”. To tell the time of day when something happened, an Indian pointed to the sky. He showed where the sun had been at the time.
Indians usually used signals when they wanted to send messages to someone far away. To make signals, an Indian might use a pony. He might use a blanket. Or he might use smoke, a mirror or fire arrows.
To signal that he had seen many animals, an Indian rode his pony in a large circle. Sometimes the Indian gave a signal like this and then went away to hide. This meant that there was danger.
The blanket signal was visible from far away. An Indian held the corners of a blanket in his hands. Then he began to swing the blanket from side to side in front of him. An Indian could send many different signals with his blanket.
He could also send many signals with a mirror. He usually used the mirror to warn someone of danger. Or he attempted to get the attention of a person far away. But he also used it to send messages in code. Of course, mirrors could be used only when the sun was shining. At night, Indians used fire arrows for signaling.
An Indian also sent signals with smoke. He made a small fire of dry wood． Then he put grass or green branches on it. He held a blanket over the fire for a minute. When he removed the blanket from the fire, there was a cloud of smoke. The number of clouds of smoke told his message in code.
Now you can see that Indians didn’t need to learn each other’s language. They could talk to one another by using signals or sign language.

“The world's oceans are slowly getting more acidic.” say scientists. The researchers from California report that the change is taking place in response to higher levels of carbon dioxide in the atmosphere.
The lowering of the waters' PH value is not great at the moment but could cause a serious threat to current ocean life if it continues, they warn. Ken Caldeira and Michael Wickett, from the Lawrence Livermore National Laboratory, report their concerns in the journal Nature. Increasing use of oil fuels means more carbon dioxide is going into the air, and most of it will eventually be absorbed by seawater. Once in the water, it reacts to form carbonic acid. Scientists believe that the oceans have already become slightly more acidic over the last century.
These researchers have tried to predict what will happen in the future by combining what we know about the history of the oceans with computer models of climate change. “This level of acidity will get much more extreme in the future if we continue releasing CO2 into the atmosphere,” said Dr Caldeira. And we predict the amount of future acidity will exceed(超过) anything we have seen over the last several hundred million years, let alone perhaps after rare disastrous events such as asteroid(小行星) impacts.
However, it is not absolutely clear what that means for ocean life. Most organisms live near the surface, where the greatest PH change would be expected to occur, but deep－ocean life forms may be more sensitive to PH changes. Coral reefs(珊瑚礁) and other organisms whose shells contain calcium carbonate(碳酸钙) may be particularly affected if the water's acidity levels keep going up, the team predict. They could find it much more difficult to build these structures in water with a lower PH.
In recent years some people have suggested storing carbon dioxide from power station in the deep ocean as a way of dealing with global warming. But Dr Caldeira said that such a strategy should now be re—considered. “Previously, most experts had looked at ocean absorption of carbon dioxide as a good thing——because in releasing CO2 into the atmosphere we warm the planet, and when CO2 is absorbed by the ocean, it reduces the amount of greenhouse warming.”
57．The ocean is becoming more acidic due to_______.
A．the lower water PH value B．the warming atmosphere
C．the higher level of CO2 in the air D．the increasing use of oil fuels
58．According to Dr Caldeira,________.
A．ocean absorption of carbon dioxide is a good thing
B．more oil fuels will be used in the near future
C．scientists may predict climate changes with computer models
D．the future situation of the amount of acidity is extremely serious
59．If the water's acidity level keeps rising,____________.
A．ocean life whose structures contain calcium carbonate may be affected
B．the water's PH value will become higher and higher
C．organisms living near the surface are more sensitive to PH changes
D．some disastrous events will occur more often than before
60．Most experts once believed storing carbon dioxide in the ocean would reduce_________
A．the CO2 absorbed by the ocean B. the amount of greenhouse warming
C．the acidity of the ocean D．the gradual release of CO2

The most detailed breakdown(分析) of ethnic and gender performance in national curriculum tests for 7, 11 and 14－year－olds shows that Chinese pupils do best in every subject at every age. Chinese and Indian pupils outperformed white British children in English tests for 11－year－olds. In all, 83% of Chinese students reached the required standard compared with 78% of Indian pupils and 75% of white UK pupils and only 65% of Bangladeshi children reaching level four, the standard that an 11－year－old should achieve.
While the overall results show the performance of every ethnic group at GCSE(中等教育普通证书) is improving, they do highlight a worrying trend for white British pupils. David Miliband, the minister for School Standards, said the results showed that while standards in secondary schools were rising, there was “a shocking gender gap between boys and girls”. He added: “58.2% of girls achieved five A to C grade passes at GCSE in 2003 compared with just 49.9% of boys, and white working－class boys are one of the lowest performing groups at 14.” According to researchers,” In the weeks leading up to GCSE unsupervised study leave at home in many areas has become the norm(惯例). They are left to their own devices.” Mr. Miliband is supporting a plan to persuade schools to drop study leave before GCSEs and replace it with structured revision in school.
53．What's the best title for this text?
A．Chinese－British Pupils' Education in Britain
B．British Primary Education
C．British Ethnic Minority Education
D．The GCSE In Britain
54．All UK 11－year－olds' required standard in English tests is that they should reach .
A．grade A B．grade B C．grade C D．level 4
55．What worries David Miliband according to the text?
A．Chinese－British and Indian－British pupils surpass British pupils in every subject.
B．White working class boys perform worst in schools.
C．Girls perform much better than boys.
D．Before GCSE all students are asked to do revision at school by themselves.
56．According to David Miliband, the study leave before GCSE is .
A．unacceptable B．practical C．admirable D．Understandable
