Mothers and daughters go through so much—yet when was the last time a mother and daughter sat down to write a book together about it all? Perri Klass and her mother, Sheila Solomon Klass, both gifted professional writers, prove to be ideal co-writers as they examine their decades of motherhood, daughterhood, and the wonderful ways their lives have overlapped (重疊).

Perri notes with amazement how closely her own life has mirrored her mother’s: both have full-time careers; both have published books, articles, and stories; each has three children; they both love to read. They also love to travel—in fact, they often take trips together. But in truth, the harder they look at their lives, the more they acknowledge their big differences in circumstance and basic nature.

A child of the Depression (大蕭條), Sheila was raised in Brooklyn by parents who considered education a luxury for girls. Starting with her college education, she has fought for everything she’s ever accomplished. Perri, on the other hand, grew up privileged in the New Jersey suburbs of the 1960s and 1970s. For Sheila, wasting time or money is a crime, and luxury is unthinkable while Perri enjoys the occasional small luxury, but has not been successful in trying to persuade her mother into enjoying even the tiniest thing she likes.

Each writing in her own unmistakable voice, Perri and Sheila take turns exploring the joys and pains, the love and bitterness, the minor troubles and lasting respect that have always bonded them together. Sheila describes the adventure of giving birth to Perri in a tiny town in Trinidad where her husband was doing research fieldwork. Perri admits that she can’t sort out all the mess in the households, even though she knows it drives her mother crazy. Together they compare thoughts on bringing up children and working, admit long-hidden sorrows, and enjoy precious memories.

Looking deep into the lives they have lived separately and together, Perri and Sheila tell their mother-daughter story with honesty, humor, enthusiasm, and admiration for each other. A written account in two voices, Every Mother Is a Daughter is a duet (二重奏) that produces a deep, strong sound with the experiences that all mothers and daughters will recognize.

1.Why does Perri think that her own life has mirrored her mother’s?

A. They both have gone through difficult times.

B. They have strong emotional ties with each other.

C. They have the same joys and pains, and love and bitterness.

D. They both have experiences as daughter, mother and writer.

2.The word “l(fā)uxury” in Paragraph 3 means ______.

A. something rare but not pleasant

B. something that cannot be imagined

C. something expensive but not necessary

D. something that can only be enjoyed by boys

3.What is Paragraph 4 mainly about?

A. The content of the book.?????????? B. The purpose of the book.

C. The influence of the book.????????? D. The writing style of the book.

4.How are women’s lives explored in this book?

A. In a musical form.??????????????? B. Through field research.

C. With unique writing skills.???????? D. From different points of view.

What if we could replace oil with a fuel which produced no pollution and which everybody had equal access to?The good news is that we can, In fact, we are swimming in it—literally.

Hydrogen is one of the building blocks of the universe ,Our own sun is basically ,a big ,dense cloud of the stuff ,And hydrogen can be used to create electricity for power ,heat and light.

The problem is that hydrogen is everywhere and nowhere at the same time , It does not exist as a material on its own ,but is always part of something else, So it has to be separated before it can be used.

Most commercial hydrogen in use now is created from natural gas , As oil will start to run out in around the year 2030.,it makes sense to produce as much hydrogen as possible as soon as we can ,But natural gas supplies will also begin to run out soon after, Another source is needed.

Researchers are now using electricity to make water into hydrogen ,Companies are working on the problem in their own areas ,The first commercial hydrogen ,”fuel cells”for computers and mobile phones have already come on to the market ,Auto companies have also invested over US $2billion in the production of hydrogen fuelled cars

Thd nations of a hydrogen fuelled planet would not fight over evergy recourses, There would be a great reduction in pollution ,The only by-product of creating hydrogen is pure drinking water—something that is very scarce in many parts of the world ,But that is not where the good news ends, Once the costs of producing hydrogen have been brought down ,it will possibly provide power for a third of the Earth ‘s population that has no electricity.

And electricity creates wealth, In South A frica over the last decade there has been a large programme of electrification, Thanks to the programme, people do not have to spend their days looking firewood to burn for heat, And with electric light , they can work long into the night.

Some scientists see radical changes in the way the human race co-operates, Hydrogen creates clectricity, and is also created by it. With dual use fuel cells, everyone who consumes energy could also produce it ,Late at night, a man drives home in London and connects his car into the “world-wide hydrogen web”, which it supplies with electricity ,A few hours later, a man in Beijing uses that electricity to power the hydrogen cell in his car, Hydrogen could be the first democratic energy source.

Like all dreams of the future, it seems very far away, But the threat of war and terrorism in the Middle East has made governments and businesses more aware of the need to edn oil dependency and spend more time and money on hydrogen resource, So maybe the threat of war is not a completely bad thing for the future of the human race.

1.What does the underlined word “it”in the last but one paragraph refer to?

A、wealth                  B、hydrogen             C、electricity             D、fuel

2.What is the problem with using hydrogen as energy?

A、It has by-products

B、It has to be separated from other materials

C、It will make energy too cheap

D、It is too far away from us

3.Why does the author give the example in the last but one paragraph?

A、To tell us that we produce energy while using hydrogen power

B、To tell us that hydrogen power does not produce pollution

C、To show hydrogen power can stop war

D、To show hydrogen power is cheap

4.What is the author’s attitude about the future?

A、skeptical               B、negative               C、indifferent           D、positive

5.What is the passage mainly about?

A、war and energy 

B、the future of hydrogen as an energy resource

C、the disadvantages of oil

D、How to end war

Back in old times, people had little knowledge about the universe and nature. Things we now consider to be common sense were mysteries to our ancestors.

Over the years, major breakthroughs have been made in science and many phenomena have been explained. But still, there are always questions we can't yet answer, and The Guardian has listed some of them.

1. What makes us human?

Just looking at your DNA won't tell you - human DNA is 99 percent identical to that of the chimpanzee and, believe it or not, 50 percent identical to a banana's! A lot of the things we once thought were unique about us - language and tool use, recognizing ourselves in the mirror and so on – have since been seen in other animals. Perhaps it's our culture that makes the difference or maybe our ability to use fire. It's also possible that our capacity (能力) for co-operation and our trading skills are what make us unique.

2. Why do we dream?

Given the fact that we spend around a third of our lives sleeping, shouldn't we know everything about it? Unfortunately, scientists are still searching for a complete explanation of what happens when we sleep and why we dream.

Austrian psychologist Sigmund Freud believed dreams were the expressions of wishes that we can't fulfill in our real lives. Others have wondered whether dreams are just random "noise" coming from a sleeping brain.

3. Could we someday live forever?

Apart from accidents, most people die because of diseases that can be treated and aging. And since many diseases, such as diabetes(糖尿。 and cancer, are diseases of aging, treating aging itself could be the key to extending our lives.

Our knowledge of what causes us to age - and what allows some animals to live longer than others - is expanding rapidly. And though we haven't quite worked out all the details, we've worked out some pieces of the puzzles such as DNA damage and metabolism (新陳代謝), which are all leading to the invention of drugs that can slow down the aging process.

If we're lucky enough to lengthen our lives, we might even get to see the day when all of these questions are answered.

1.The main point of the passage is ______.

A. to inform people of the knowledge about the universe and nature

B. to introduce major breakthroughs that have been made in science

C. to present some questions we can't yet answer

D. to explain what were once mysteries to our ancestors

2.Chimpanzees and bananas are mentioned as examples to prove that ______.

A. human beings are actually not different from other animals

B. animals have completely different DNA from that of plants

C. both animals and plants share the same amount of DNA

D. DNA alone is not good enough to make humans different

3.The underlined word "identical" is closest in meaning to ______.

A. mysterious          B. unique     C. advanced             D. same

4.Which of the following statements is TRUE according to the passage?

A. What were mysteries to our ancestors are considered to be common sense now.

B. Now we know much more about dreams than our ancestors did in the past.

C. With the invention of new drugs people can possibly live even longer.

D. If all the diseases can be treated people can theoretically live forever.

The American local food movement has been all about buying seasonal food from nearby farmers. Now, thanks to the Web, it is expanding to include far-away farmers too. A new start-up, Foodzie, is an online farmers market where small food producers and growers can sell their products.

Foodzie was started by Mr LaFave and two of his friends, who met during college at Virginia Tech, where they would pay frequent visits to farmers markets. Last year, while living in North Carolina, one of them, Emily Olson, now 24, came up with one idea. She was working as a brand manager for a gourmet grocery chain and realized that people who enjoyed fine food but didn’t work in the business had no way to discover handmade foods outside their local farmers markets. Small farmers had no way of finding or selling to faraway customers, either.

   Mr LaFAve and the third co-founder, Nik Bauman, both 25, worked in corporate sales and software development. “With business, food and computer science backgrounds, we figured we had everything we needed.” Mr LaFAve said.

   The three quit their jobs, and opened this site to the public in December and the site has had 43,000 visitors in the past month. So far, 29 sellers have opened shops and 41 are in the process of opening them. The founders recently hired a fourth employee to help Ms Olson recruit(吸收) new food producers at farmers markets and food shows. Mr LaFAve is convinced that the recession(經(jīng)濟衰退) will not reduce people’s interest in buying locally grown and handmade food. “There is misunderstanding that all these foods are more expensive than mass-produced alternatives,” he said. “People are pouring their heart and soul into these products, and they are of the highest quality. ”

1. The passage is mainly about _______________.

   A. how an online farmers’ market works

   B. the American local food movement

   C. three youths starting an online farmers’ market

   D. the reasons why people are interested in local food

2.Why did the founders start the online farmers’ market?

   A. Because it met the need of the market.

   B. Because the founders were interested in seasonal food.

   C. Because some people wanted to buy locally grown food.

   D. Because farmers wanted to sell their foods.

3. The underlined word in Paragraph 2 can be used to describe ______________.

   A. food of high quality    B. terrible food    C. food of low fat   D. fried food

4.The founders of the site employed another person to help _______________.

   A. open new shops in faraway markets

   B. buy locally grown and handmade food

   C. find more food outside their local farmers’ markets

   D. find more food growers to open shops on their site

5.About the three founders, we know that ________________.

   A. they are of the same age             B. to start the website they gave up their work

C. they used to be colleague            D. they majored in farming at college

科目:高中英語 來源:20102011學(xué)年福建省高二下學(xué)期第一次月考英語卷 題型:閱讀理解

On the outside Betsy Lueth’s school looks like any other in Minneapolis. Yet inside, it is

Yinghua Academy, a public school where elementary(小學(xué))students study subjects ranging from

math to American history in Chinese.

    Yinghua, the first such immersion(沉浸式)program in the Midwest is on the leading edge (前沿) of a movement that in recent years has seen Chinese language programs spread rapidly throughout the U.S.

The idea behind Yinghua is to introduce kids to the language and culture as early as possible —ideally, before age 12. Kindergarteners and first graders are taught in Chinese and a single period of English is introduced in second grade. By sixth grade, kids are learning half in English and half in Chinese, with the expectation of fluency in both. In Yinghua’s classrooms, the walls are covered not with ABCs but with pictures and Chinese characters.

There are many challenges at Yinghua. Most teachers come from Taiwan or mainland China, and cultural misunderstandings are very common. Lueth’s teachers are learning to be tolerant of local customs — as well as a lot more parental input (家長看法) than they are used to. “In China, teachers are respected. They are not questioned,” says Luyi Lien, Yinghua’s Taiwan-born director. “In America, parents are more expressive of their opinions.”

Research has shown that in the long run, immersion programs can provide benefits, including more flexible, creative thinking. Though students from the programs fall behind for a few years in English, by fifth grade they perform as well as or better than their monolingual(單語言)peers on standardized reading and math tests. For multicultural families, the psychological (心理上的) help can also be important. Lueth, a former teacher, co-founded the school as a way to expose her adopted Chinese daughter Lucy to her native culture. Lucy used to be annoyed when cousins asked why her skin color was different from theirs; before she started at Yinghua, she resisted exploring anything related to China. Now, Lueth says, Lucy proudly answers her cousins, “Yeah, I was born in China.”

1.Yinghua is different from other schools in Minneapolis in the way that_________.

    A.it offers subjects to students mostly in Chinese

    B.its language program is popular in the U.S.A

    C.kids there begin to learn Chinese at the age of 12

    D.its students learn subjects half in English and half in Chinese

2..One of the challenges at Yinghua is that_________.

    A.most parents do not respect its teachers

    B.teachers need to get used to the local culture

    C.its students are mostly from nontraditional families

    D.there is misunderstanding between teachers and students

3.We can learn from the last paragraph that immersion program _________.

    A.enables students pass tests more easily

    B.benefits students in learning psychology

    C.helps some students accept the local customs

    D.contributes to the better development of students

4.Which of the following is TRUE according to the passage?

    A.Teachers in Yinghua have difficulty in understanding the local culture.

    B.Parents are discouraged to speak out their opinions of the school in Yinghua.

    C.The students in Yinghua are expected to speak English and Chinese fluently.

    D.Yinghua is the first school in the USA to introduce Chinese culture to students.
