Global surface temperatures have increased 0.6—1.2 degrees since the late 19th century. The 20th century’s 10 warmest years all happened within the last 15 years. Of these,1998 was the warmest year on record. The snow covering the Northern Hemisphere(半球)and floating ice in the Arctic Ocean decreased. Globally, sea level has risen 4—10 inches over the past century. World-wide amount of rain and snow over land has increased by about one percent. The number of major rainfall events has increased throughout much of the United States.
Increasing concentrations(集中)of greenhouse gases are likely to make climate change faster. Scientists expect that the average global surface temperature could rise 1.6—6.3 degrees by 2100,and the climate in different areas could change differently. Evaporation(蒸發(fā))will increase as the climate warms, which will increase average global amount of rain and snow. Soil moisture(潮濕)is likely to decrease in many areas, and strong rainstorms are likely to become more frequent.Sea level is likely to rise two feet along most of the U.S coast.
Calculations of climate change for certain areas are much less able to be trusted than global ones, and it is unclear whether the climate in different areas will become more variable(變化無常的).
64.Which of the following statements is not mentioned in the first paragraph?
A.The snow has been seen covering the Southern Hemisphere .
B.More and more major rainfall events have happened to the U.S.
C.On the whole earth, sea level has risen 4—10 inches.
D.The amount of the rain in the world has increased by about 1%.
65.According to scientists, the reason why the climate becomes warm is that________.
A.the snow covering Northern Hemisphere has decreased
B.evaporation has increased in the recent years
C.greenhouse gases concentrate increasingly
D.the floating ice in the Arctic Ocean has decreased
66.It is because______ that strong rainstorms become more frequent.
A.a(chǎn)verage global little of rain and snow increases
B.the climate becomes warm
C.soil moisture decreases
D.sea level rises two feet

Global warming is one of the major environmental problems we are facing today. Scientists think a further rise in the carbon dioxide levels will make this situation worse. The greenhouse effect causes the earth’s heat to be trapped in the atmosphere, which results in the increase in temperature. This in turn has an effect on various plants and animals. Global warming makes it difficult for some of them to survive.
Ozone depletion(臭氧耗損) means a drop in the quantity of the ozone in the earth’s stratosphere (平流層). The ozone hole in the Antarctic is mainly due to the release of CFCs ( a type of gas). Because of ozone depletion, humans are facing various problems such as the harmful effects of UV rays.
Water pollution is caused when wastes are thrown into water. What’s more, many harmful chemicals are also put into water, which causes the deaths of many wild animals and endangers the health of humans.
The increasing population is causing a loss of natural resources. This is related to various human activities. For example, overfishing has caused many kinds of fishes to die out. Forests are being cleared to meet the rising demand for paper, wood, even for land. Mining(采礦) has led to a further drop in mineral resources. If we used up all the resources, how could our children survive on this planet?
These are some of the current environmental problems we are facing today. Only with an effort from each person, can we hope to save our planet from being destroyed.

When we think about education and language learning, we are most likely to think of books. Although there are lots of language learning methods, many people still prefer to learn only by using books. So what are the advantages of learning a language from a book?
Here are its advantages: firstly, you can take language books wherever you go conveniently and you can use them whenever you want. Secondly, they are easy to follow because the courses in them are usually planned for you in strict order starting from the most basic concepts to the more complex. Thirdly, if you are unsure of something, you can continue to work on it as quickly as you like. Lastly, books are likely to have a lot of vocabulary and a lot of topics so you will get great value out of a book with lots of materials in it.
Using books to study a language has disadvantages, too. All textbooks and dictionaries usually include some kind of pronunciation guide. These are helpful when there is no other way to learn, but this can't help you practice your pronunciation. With an audio method, you can compare your pronunciation to that of a native speaker. Besides, some words are spoken faster in one sentence or slower in another, so the pronunciation of a word may change according to the emotion or feeling you want to convey. Also, books can’t actually help you hear the language with its unique rhythms spoken by native speakers. With an audio language learning method, you will be able to hear and understand the language better.
Therefore, if you can supplemental(補充)your book with some other language tools, such as audio tapes, internet radio or resources such as music or television, you will have a much better chance of understanding the books' pronunciation guide and using it to get a good grasp of the spoken language.
Title: One of the Language Learning 81.__________— Using Books
Themes
To get a good grasp of the spoken language, we need to combine language learning books with an audio component
82.__________
*It’s 83. __________ and easy to take books with you. You can use them at anytime.

Every baby born a decade from now will have its genetic code (基因編碼) mapped at birth, the head of the worlds’ leading genome sequencing (基因圖譜) company has predicted.
A complete DNA read – out for every newborn will be technically possible and affordable in less than five years, promising a revolution in healthcare, says Jay Flatley, the chief executive of Illumina. Only social and legal problems are likely to delay the age of “genome sequences,” or genetic profiles. By 2019 it will have become routine to map infants’ genes when they are born, Dr Flatly told The Times.
This will open a new approach to medicine, by which conditions such as high blood pressure and heart disease can be predicted and prevented and drugs used more safely and effectively.
A baby’s genome can be discovered at birth by a blood test. By examining a person’s genome, it is possible to identify raised risks of developing diseases such as cancers. Those at high risk can then be screened more regularly, or given drugs or dietary advice to lower their chances of becoming ill.
Personal genomes could also be used to ensure that patients get the medicine that is most likely to work for them and least likely to have side – effects.
The development, however, will raise legal concerns about privacy and access to individuals’ genetic records.
“Bad things can be done with the genome. It could predict something about someone – and you could possibly hand the information to their employer or their insurance company.” said Dr Flatley.
“People have to recognize that this horse is out of the barn, and that your genome probably can’t be protected, because everywhere you go you leave your genome behind. Complete genetic privacy, however, is unlikely to be possible”, he added.
As the benefits become clearer, however, he believes that most people will want their genomes read and interpreted. The risk is nothing compared with the gain.
64.In the first two paragraphs, the author mainly wants to tell us about__________.
A.the significant progress in medicine      
B.the promise of a leading company
C.the information of babies’ genes    
D.the research of medical scientists
65.Which of the following is a problem caused by this approach?
A.The delaying in discovering DNA.
B.The risk of developing diseases at birth.
C.The side – effects of medicine on patients.
D.The letting out of personal genetic information.
66.What does the underlined sentence “… this horse is out of the barn” mean?
A.Genetic mapping technique has been widely used.
B.Genetic mapping technique is too horrible to control.
C.People are eager to improve genetic mapping technique.
D.people can’t stop genetic mapping technique advancing.
67.What’s Dr Flatley’s attitude towards the technology?
A.Tolerant.   B.Conservative.   C.Positive.   D.Doubtful.

Parents should stop blaming themselves because there’s not a lot they can do about it. I mean the teenager problem. Whatever you do or however you choose to deal with it, at certain times a wonderful, reasonable and helpful child will turn into a terrible animal.
I’ve seen friends deal with it in all kinds of different ways. One strict mother insisted that her son, right from a child, should stand up whenever anyone entered the room, open doors and shake hands like a gentleman. I saw him last week when I called round. Sprawling himself on the sofa in full length, he made no attempt to turn off the loud TV he was watching as I walked in, and his greeting was no more than a quick glance at me. His mother was ashamed. “I don’t know what to do with him these days,” she said. “He’s forgotten all the manners we taught him.”
He hasn’t forgotten them. He’s just decided that he’s not going to use them. She confessed(坦白) that she would like to come up behind him and throw him down from the sofa onto the floor.
Another good friend of mine let her two daughters climb all over the furniture, reach across the table, stare at me and say, “I don’t like your dress; it’s ugly.” One of the daughters has recently been driven out of school. The other has left home.
“Where did we go wrong?” her parents are now very sad. Probably nowhere much. At least, no more than the rest of that unfortunate race, parents.
71. This text is most probably written by ______.
A. A specialist in teenager studies.      B. a headmaster of a middle school
C. a parent with teenage children       D. a doctor for mental health problems

D. the advice that parents want their children to follow
73. The boy on the sofa would most probably be described as ______.
A. lazy       B. quiet       C. unusual       D. rude
74. From the second example we can infer that the parents of the two daughters ______.
A. pay no attention to them          B. are too busy to look after them
C. have come to hate them           D. feel helpless to do much about them
75. What is the author’s opinion about the sudden change in teenage children?
A. Parents have no choice but to try to accept it.
B. Parents should pay still more attention to the change.
C. Parents should work more closely with school teachers.
D. Parents are a fault for the change in their children.

What is blood? It is the red liquid which comes out of your finger when you cut it. There are bout thirteen pints(品脫) of blood in a man' s body. He can give a pint of blood at a time to
blood bank for the use of other men who may need it. A healthy body makes up one pint of bloo
quickly.
What does our blood do for us? It takes food to all parts of our bodies and takes waste awa
from them. All the parts of our bodies are made up of cells, and these cells, which are very small
all need food all the time.
The blood is like a stream. The cells take what they need out of the blood stream, as plants an fishes take their food out of water. The blood stream carries food and oxygen which it has taken up our lungs to all the cells in the body.

C
A new study in West Africa shows how farm irrigationsystems powered by the sun can pro-duce more food and money for villagers. The study-in Benin found that solar - powered pumpsare effective in 8upplying water, especially during the long dry season.
Sub - Saharan Africa is the part of the world with the least food security. The United Na-tions Food and Agriculture Organization estimates that more"than one biillion of the world' s peo-ple faced hunger last year.Around 265 million of them live'south of the Sahara Desert:  Lack of  rainfallis one oftheir main causes offood shortages..
Jennifer Bumey from Stanford University in Califomia led the study.The research team helped build three solar - powered drip irrigation -(滴灌) ,systems in northem Benin. Between 30 and 35 women used each system to pump water from the ground or a stream.Each woman was responsible for farming her own 120 sqrurre meters of land. They also farmed other land  collectively.
The solar - powered irrigation systems produced an average of nearly two tons of vegetables per montb. During the first year, the women.kept a monthly average of almost rune kilograms of vegetables for home use.They sold the surplus produce at local markets. The eamings greatly increased their ability to buy food during the dry season which can last six to nine months. Peo- ple in the'two villages with the systems were able to eat three to five more servingsof yegetables per day.But making the surplus available at markets also had a wider effect.
The study compared the villages with two others where women farmed with traditional methods like carrying water in buckets. The amount of vegetables eaten in those villages also  increased, though not as much.The researchers note that only four percent of the croplamd in sub - Saharan Africa is irrigated. Using solar power to pump water has higher costs at first. But    the study says it can be more economical in the long term than using fuels like gasoline,  diesel  or kerosene. And solar power is environmentally friendly.
66.Food security in Sub - Saharan Africa is insufficient mainly because of
A.lack of rainfall         B.limitation of farmland
C. a small crop variety   D.little sunlight
67.From the third paragraph we know that _______.
A.water is wasted by using the system
B. the farmers imgate the land together
C. all farmers use irrigation systems in northem Benin
D. the solar - powered systems take up more manpower
68.The underlined word "surplus" in the 4th paragraph most probably means_______
A.special             B.unnecessary      C.extra      D.a(chǎn)bandoned
69.Usinf.solar power to pump water has advantages EXCEPT that
A.solar energy has higher cost at first
B.solar power helps to protect environment
C.solar power helps farmers increase eanungs
D. solar energy can be more economical in the long run
70.What can be the best title for the text?
A.Manpower affects rainfallin Africa
B.Irrigation by carrying water in buckets
C.Solar - powered pumps aid African farmers
D.Vegetable supply increased in African villages
