科目：高中英語 來源：2017屆貴州遵義航天高中高三上第二次模擬考試英語卷（解析版） 題型：閱讀理解

Two of the saddest words in the English language are “if only”. I live my life with the goal of never having to say those words, because they convey regret, lost opportunities, mistakes, and disappointment.

My father is famous in our family for saying, “Take the extra minute to do it right.” I always try to live by the “extra minute” rule. When my children were young and likely to cause accidents, I always thought about what I could do to avoid an “if only” moment, whether it was something minor like moving a cup full of hot coffee away from the edge of a counter, or something that required a little more work such as taping padding (襯墊) onto the sharp corners of a glass coffee table.

I don’t only avoid those “if only” moments when it comes to safety. It’s equally important to avoid “if only” in our personal relationships. We all know people who lost a loved one and regretted that they had foregone an opportunity to say “I love you” or “I forgive you.” When my father announced he was going to the eye doctor across from my office on Good Friday, I told him that it was a holiday for my company and I wouldn’t be here. But then I thought about the fact that he’s 84 years old and I realized that I shouldn’t give up an opportunity to see him. I called him and told him I had decided to go to work on my day off after all.

I know there will still be occasions when I have to say “if only” about something, but my life is definitely better because of my policy of doing everything possible to avoid that eventuality. And even though it takes an extra minute to do something right, or it occasionally takes an hour or two in my busy schedule to make a personal connection, I know that I’m doing the right thing. I’m buying myself peace of mind and that’s the best kind of insurance for my emotional well-being.

1.Which of the following is an example of the “extra minute” rule?

A. Start the car the moment everyone is seated.

B. Leave the room for a minute with the iron working.

C. Wait for an extra minute so that the steak tastes better.

D. Move an object out of the way before it trips someone.

2.The author decided to go to her office on Good Friday to ________.

A. keep her appointment with the eye doctor

B. meet her father who was already an old man

C. join in the holiday celebration of the company

D. finish her work before the deadline approached

3.The underlined word “foregone” in Paragraph 3 is closest in meaning to ________.

A. avoidedB. lackedC. abandonedD. took

4.What is the best title for the passage?

A. The Emotional Well-being

B. The Two Saddest Words

C. The Most Useful Rule

D. The Peace of Mind

“A good book for children should simply be a good book in its own right", says Mollie Hunter. Born and brought up near Edinburgh, Mollie has devoted her talents to writing primarily for young people．She firmly believes that there is and should always be a wider audience for any good book whatever its main market is．In Mollie’s opinion, it is necessary to make full use of language and she enjoys telling a story, which is what every writer should be doing．"If you aren't telling a story, you’re a very dead writer indeed．" she says．With the chief function of a writer being to entertain, Mollie is indeed an entertainer．"I have this great love of not only the meaning of language but of the music of language,’ she says, "This love goes back to early childhood．I had a school teacher who used to ask us what we would like to be when we grew up and, because my family always had dogs, and I was very good at handling them, I said I wanted to work with dogs, and the teacher always said ‘Nonsense, Mollie; dear, you’ll be a writer.’ So finally I thought that this woman must have something, since she was a good teacher and I decided when I was nine that I would be a writer．"

This childhood intention is described in her novel, A Sound of Chariots, which although written in the third person is clearly autobiographical（自傳體的） and gives a picture both of Mollie’s ambition and her struggle towards its achievement．Thoughts of her childhood inevitably（不可避免地） brought thoughts of the time when her home was still a village with buttercup（金鳳花）meadows and strawberry fields—sadly now covered with modern houses．"I was once taken back to see it and I felt that somebody had lain dirty hands all over my childhood．I’ll never go back, "she said．"Never．When I set one of my books in Scotland” she said, “I can recall my romantic feelings as a child playing in those fields, or watching the village blacksmith at work．And that’s important because children now know so much so early that romance can't exist for them, as it did for us.”

1.What does Mollie Hunter feel about the nature of a good book?

A．It should not aim at a narrow audience.

B．It should be attractive to young readers.

C．It should be based on original ideas.

D．It should not include too much conversation.

2.In Mollie Hunter’ s opinion, which of the following is one sign of a poor writer?

A．Being poor in life experience.

B．Being short of writing skills.

C．The weakness of description.

D．The absence of a story.

3.What do we learn about Mollie Hunter as a young child?

A．She expected to become a writer.

B．She didn’t enjoy writing stories.

C．She didn’t have any particular life aims.

D．She didn’t respect her teacher’ views.

4.What’s the writer’s purpose in this text?

A．To share her enjoyment of Mollie Hunter’s book.

B．To introduce Mollie Hunter’s works to a wider audience．

C．To provide information for Mollie Hunter’s existing readers．

D．To describe Mollie Hunter’s most successful books．

What is your favorite color? Do you like yellow, orange, red? __1.___ Do you prefer greys and blues? Then you are probably quiet, shy, and you would rather follow than lead. You tend to be pessimist. At least, this is what psychologists tell us, and they should know, because they have been seriously studying the meaning of color preference, as well as the effect that colors have on human beings. _2.___ If you happen to love brown, you did so, as soon as you opened your eyes, or at least as soon as you could see clearly.___ 3._. A yellow room makes most people feel more cheerful and more relaxed than a dark green one; and a red dress brings warmth and cheer to the saddest winter day. __4.__ A black bridge over the Thames River, near London, used to be the scene of more suicides(自殺) than any other bridge in the area—until it was repainted green. The number of suicide attempts immediately fell sharply. Perhaps it would have fallen even more if the bridge had been done in pink or baby blue.

__5.___. It is an established fact that factory workers work better, harder, and have fewer accidents when their machines are painted orange rather than black or grey.

Until late in the 20th century, most Americans spent time with people of generations. Now mid-aged Americans may not keep in touch with old people until they are old themselves. That’s because we group people by age. We put our three-year-olds together in day-care center, our 13-year-olds in school and sports activities, and our 80-year-olds in senior-citizen homes. Why?

We live away from the old for many reasons: young people sometimes avoid the old to get rid of fears for aging and dying. It is much harder to watch someone we love disappear before our eyes. Sometimes it’s so hard that we stay away from the people who need us most.

Fortunately, some of us have found our way to the old. And we have discovered that they often save the young.

A reporter moved her family onto a block filled with old people. At first her children were disappointed. But the reporter baked banana bread for the neighbors and had her children deliver it and visit them. Soon the children had many new friends, with whom they shared food, stories and projects. “My children have never been less lonely,” the reporter said.

The young, in turn, save the old. Once I was in a rest home when a visitor showed up with a baby. She was immediately surrounded. People who hadn’t gotten out of bed in a week suddenly were ringing for a wheelchair. Even those who had seemed asleep wake up to watch the child. Babies have an astonishing power to comfort and cure.

Grandparents are a special case. They give grandchildren a feeling of security and continuity. As my husband put it, “my grandparents gave me a deep sense that things would turn out right in the end.”

Grandchildren speak of attention they don’t get from worried parents. “My parents were always telling me to hurry up, and my grandparents told me to slow down,” one friend said. A teacher told me she can tell which pupils have relationships with grandparents: they are quieter, calmer, more trusting.

1.Now in an American family, people can find that ________.

A. children never live with their parents

B. not all working people live with their parents

C. aged people are supported by their grandchildren

D. grandchildren are supported by their grandparents

2.The reason why old people are left alone may be that ________.

A. the old don’t like to live in a big family

B. the young can’t get enough money to support the old

C. different generations have different lifestyles

D. the old are too weak to live with the young

3.The fact that the reporter told us shows that ________.

A. old people in America lead a hard life

B. old people in America enjoy banana bread

C. she had no time to take care of her children

D. old people are easy to get along with

4.Seeing a baby, the old people get excited because ________.

A. they had never seen a baby before

B. the baby was clever and beautiful

C. the baby brought them the image of life

D. the baby’s mother would take care of them
