A recent study of ancient and modern elephants has  come up with the unexpected conclusion that the African elephant is divided into two distinct (不同的) species
The discovery was made by researchers at York and Harvard universities when they were examining the genetic relationship between the ancient woolly mammoth and mastodon to modern elephants—the Asian elephant, African forest elephant and African savanna elephant
Once they obtained DNA sequences (序列) from two fossils (化石),mammoths and mastodons, the team compared them with DNA from modern elephants. They found to their amazement that modern forest and savanna elephants are as distinct from each other as Asian elephants and mammoths.
The scientists used detailed genetic analysis to prove that the African savanna elephants and the African forest elephants have been distinct species for several million years. The divergence of the two species took place around the time of the divergence of Asian elephants and woolly mammoths. This result amazed all the scientists.
There has long been debate in the scientific community that the two might be separate species but this is the most convincing scientific evidence so far that they are indeed different species.
Previously, many naturalists believed that African savanna elephants and African forest elephants were two populations of the same species despite the elephants’ significant size differences. The savanna elephant has an average shoulder height of 3.5metres while the forest elephant has an average shoulder height of 2.5metres. The savanna elephant weighs between six and seven tons, roughly double the weight of the forest elephant. But the fact that they look so different does not necessarily mean they are different species. However, the proof lay in the analysis of the DNA.
Alfred Roca, assistant professor in the department of Animal Sciences at the University of Minois, said, “We now have to treat the forest and savanna elephants as two different units for conservation purpose. Since 1950 all African elephants have been conserved as one species. Now that we know the forest and savanna elephants are two very distinct animals, the forest elephant should become a bigger priority (優先)for conservation purpose .”
【小題1】One of the fossils studied by the researchers is that of ________.

A.the Asian elephantB.the forest elephant
C.the savanna elephantD.the mastodon elephant
【小題2】The underlined word “divergence” in paragraph 4means “________”
A.evolutionB.exhibitionC.separationD.examination
【小題3】The researcher’s conclusion was based on a study of the African elephant’s _____
A.DNAB.heightC.weightD.population
【小題4】What were Alfred Roca’s words mainly about?
A.The conservation of African elephants.
B.The purpose of studying African elephants
C.The way to divide African elephants into two units
D.The reason for the distinction of African elephants
【小題5】Which of the following can be the best title for the passage?
A.Naturalist’s Belief about Elephants.
B.Amazing Experiment about Elephants
C.An Unexpected Finding about Elephants
D.A Long scientific Debate about Elephants

C
Two Earthquakes in Two Months:
Comparing the Quakes in Haiti (海地) and Chile (智利)
Overview (概要) How do the earthquakes in Chile and Haiti compare? Here, students perform a gallery walk to learn more about the earthquakes from a specific point, and then do a specific research and presentation project or response activity. Finally, they seek answers to their unanswered questions.
Materials Print copies of photographs, charts, documents and other visuals to display, as described below; computer (s) with Internet access (optional), research materials, handouts.
Warm-up Choose and prepare a “gallery” of photographs, graphics, news reports and other materials to display around the room to enable students to consider the 2010 earthquake in Chile.
Depending on course program, choose materials for the gallery that provide a window on the two quakes, through one of the following specific points, or the focus of your choice:
Earthquakes through History Putting the 2010 Chilean and Haitian quakes into historical view related to other earthquakes, including the 1960 Chilean quake and the 2004 Asian earthquake and tsunami.
Rescue and Aid Considering domestic and international response to the disasters by militaries, governments and aid organizations, including rescue and recovery as well as efforts to provide food, water, health care and shelter to those affected.
Related The article Underwater Plate Cuts 400 Mile Gash compares several earthquakes:
Mr. Lin figured that the quake on Saturday was 250 to 350 times more powerful than the Haitian quake.
But Paul Caruso noted that at least on land, the effects of the Chilean tremor (震動) might not be as bad. For one thing, he said, the quality of building construction is generally better in Chile than in Haiti. And the fact that the quake occurred offshore should also help limit the destruction. In Haiti, the rupture (斷裂) occurred only a few miles from the capital, Port-au-Prince. The rupture on Saturday was centered about 60 miles from the nearest town, Chillan, and 70 miles from the country’s second-largest city, Concepción.
Read the article using the following questions.
Questions For discussion with others and reading comprehension:
How does the 2010 Chilean earthquake compare to the 1960 Chilean earthquake?
Why do scientists believe that the 2010 Chilean earthquake will not cause the same level of damage as January’s Haitian earthquake did?
How does the 2010 Chilean earthquake compare to the 2004 Indonesian earthquake?
What reasons do scientists give to explain why the Indonesian quake caused so much more damage than the recent Chilean earthquake?
64. Which of the following shows one of the reasons for slighter losses in Chile than in Haiti?
A. Position:
     
B. Power:

65. We can infer that the article Underwater Plate Cuts 400 Mile Gash includes ________.
A. the causes of the 2010 Chilean earthquake and the 1960 Chilean earthquake
B. the comparison between the 2010 Haitian and the 2004 Indonesian earthquakes
C. the reason for the 2010 Chilean quake being more powerful than January’s Haitian earthquake
D. the reason for less damage in the 2010 Chilean quake than in the 2004 Indonesian earthquake
66. What is the passage most likely to be?
A. A program for research.                          B. A guide to earthquake study.
C. An advertisement for students.                       D. An introduction to quakes.

D
Time spent in a bookshop can be most enjoyable, whether you are a book—lover or merely go there to buy a book as a present. You may even have entered the shop just to find shelter from a sudden shower. Whatever the reason, you can soon become totally unaware of your surroundings.
The desire to pick up a book with an attractive dust jacket is irresistible, although this method of selection ought not to be followed, as you might end up with a rather dull book.
You soon become interested in some book or other, and usually it is only much later that you realize you have spent far too much time there and must dash off to keep some forgotten appointment—without buying a book, of course.
This opportunity to escape the realities of everyday life is, I think, the main attraction of a bookshop. There are not many places where it is possible to do this. A music shop is very much like a bookshop. You can wander round such places to your heart’s content. If it is a good shop, no assistant will approach you with the inevitable greeting:“Can I help you, sir?” You needn’t buy anything you don’t want. In a bookshop an assistant should remain in the background until you have finished browsing. Then, and only then, are his services necessary. Of course, you may want to find out where a particular section is, but when he has led you there, the assistant should retire discreetly(謹慎地) and look as if he is not interested in selling a single book.
You have to be careful not to be attracted by the variety of books in a bookshop. It is very easy to enter the shop looking for a book on, say ancient coins and to come out carrying a copy of the latest best-selling novel and perhaps a book about brass—rubbing—something which had only slightly interested you up till then. This volume on the subject, however, happened to be so well illustrated and the part of the text you read proved so interesting that you just had to buy it. This sort of thing can be very dangerous. Apart from running up a huge account, you can waste a great deal of time wandering from section to section.
63.The underlined phrase “dust jacket” means_______.
A.a kind of clothes                        B.a paper cover of a book
C.a dusty book                            D.a title of a book
64.You may spend too much time in a bookshop because_______.
A.the dust jackets are very attractive
B.you start reading one of the books
C.it is raining outside
D.you have to make sure you won’t buy a dull book as a present
65.In a good bookshop_______.
A.all the books there are interesting       B.the assistant greets you in a warm way
C.your heart is satisfied                D.you feel that you are in a music shop
66.The best title for this passage may be_______.
A.The Attraction of Bookshops          B.How to Spend Your Time
C.Bookshops and Their Assistants       D.How to Select Books

The expression “keeping up with the Joneses” was first used in 1913 by a young American Arthur Momand. He told this story about himself: he began earning $125 a week at the age of 23. That was a lot of money in those days. Young Momand was very proud of his riches. He got married and moved with his wife to Long Island, outside New York City.
But just moving there was not enough. For when Momand and his wife saw that their neighbors belonged to a country club they too joined a club. And when he saw that rich people were expected to ride horses, Momand went horseback riding every day. Momand and his wife also hired a servant and gave grand parties for their new neighbors.
It was like a race, but one could never finish this race because one was always trying to keep up. Momand and his wife could not do that.
The race ended for them when they could no longer pay for their new way of life. They moved back to an inexpensive New York City apartment.
Momand later said that his experience had been a cruel awakening for him. However, he was able to see the funny side of it. He looked around him and noticed that many people do things just to keep up with their neighbors.
He decided that this would make good stories for many papers across the country. He called it “Keeping up with the Joneses”, because “Jones” is a very common American name. “Keeping up with the Joneses” came to mean keeping up with the people around you. Momand’s stories appeared in different newspapers for over 28 years.
People never seem to tire of keeping up with the Joneses. That is one reason why they read the “right” books, go to the “right” universities and eat in the “right” restaurants. But no matter what one does, Mr. Jones always seems to be ahead.

【小題2】The reason Momand moved to Long Island is that ___________.
A.he wanted to live in a rich neighborhood
B.there was a country club for him to join

【小題3】By saying “It was like a race”(in Para 3), the writer means ____________.
A.it was just a suitable place for the horse race
B.Momand and his wife kept themselves busy
C.Momand’s neighbors also gave parties one after another
D.Momand tried to compete with their neighbors in his way of life
【小題4】The funny side Momand saw in his experience was _________.
A.he moved back to a cheap place
B.he was not alone in keeping up with his neighbors
C.he made a mistake in following other people’s examples
D.he cared too much about what others thought of him
【小題5】Which of the following statements is NOT true according to the passage?
A.Momand earned a lot of money when he got married
B.Momand was always very interested in riding horses
C.Momand found there was something wrong with his way of life

科目:高中英語 來源:2012-2013學年黑龍江友誼縣紅興隆管理局第一中學高二月考英語卷(帶解析) 題型:閱讀理解

Why should I teach my children history? That sounds like a stupid question to even ask. But, as I hear different home schooling teachers discuss history, I get the idea that there may be different reasons for teaching history. Let me briefly explain the three good reasons for studying history and two bad reasons for studying history.
The major reason I see for studying history is that we can learn from the past. I am convinced that the world would be a much better place if more people understood the successes and failures of the past and the things that made these successes and failures. However, as the unfortunately true statement goes "the one thing we seem to learn from history is that we don't seem to learn from history." Perhaps at least in teaching history, to my children I can do a small part in changing this.
A second major reason for studying history is that it is hard to understand the current political climate in the absence of an understanding of its historical context. We can not even understand why we are and where we are without history, much less (更不必說) try to figure out where we are going or how we should get where we want to be.
I teach my children history, for one more reason. I purchased a set of historical audio (錄音機) tapes for our children. My seven-year-old son listened to them over and over. It was my hope that he would become inspired by the accomplishments of people like the Wright brothers to accomplish things by himself. I think that it is good that we celebrate the accomplishments of people like Martin Luther King Jr. if, in doing so, young people are called on to stand for the principles that he stood for and accomplish what he accomplished. I also think that by studying people like Adolph Hitler, people can learn to stand against the things that he stood for.
【小題1】The main purpose of this passage is to __________.

A.instruct the parents how to teach their children history
B.show the importance of history in politics
C.explain the reasons why children study history
D.introduce the writer’s own way of teaching history
【小題2】Which of the following is not the reason for studying history according to the author?
A.One can learn from history in order not to make the same mistakes.
B.It can help us to understand the current political climate.
C.Without history, one can be nothing but a fool in every aspect.
D.One can know the principle of doing something and not doing something.
【小題3】 Some positive historical figures are mentioned in the last paragraph to show __________.
A.people can be inspired to do good, while also learning to fight against evil
B.people may also learn from bad historical figures
C.more celebrations should be held to honor their achievements
D.today’s people can also achieve what they achieved
【小題4】 What would be talked about in the following paragraph?
A.How to teach history effectively.
B.Some negative reasons for studying history.
C.How to get more people to study history.
D.Some bad historical figures.
