【题目】 The rapid growth in skyscrapers worldwide, most of which have large windows, has led to a high demand for window washers. Though the job is well-paid, it is dangerous and accidents are not uncommon. However, if Israel-based start-up Skyline Technologies has its way, the dangerous job may soon be done by Ozmo, an intelligent window cleaning robot, with humans supervising (监督) from the safety of the ground.

Much like humans, Ozmo, sitting on platforms hanging from the buildings, uses its arms and brushes to clean the dirt on the glass. A 3D map of the building’s surface programmed into its system allows the robot to skillfully deal with any obstacle it is likely to meet, as it moves up and down the buildings. The robot will self-correct and move around every obstacle that it might have met so as not to break a window.

Unlike present window washers, the robot cleaner does not require soap to clean the glass. Instead, it uses distilled (蒸馏的) water to do the job. Yaron Schwarcz, CEO of Skyline Robotics explains, “We are environmentally friendly.”

Ozmo is also expected to be much more efficient than its human counterparts. While it presently takes three cleaners 480 hours each to clean windows of a 40-storey glass building, the robot will be able to do it in 80 hours. However, unlike other robots, Ozmo will not replace human workers, and only make their jobs safer by making them supervisors, who will be controlling the operation from the safety of the ground.

Whether Ozmo, which is still being tested, does as good a job as humans remains to be seen. If things go well, its creators have much bigger ambitions for Ozmo. Schwarcz told Forbes Magazine, “Window cleaning is just the tip of the iceberg. We plan to replace all tasks that are dangerous and dirty.”

1Why is Ozmo friendly to our environment?

A.It uses less soap than other robots.

B.It depends on solar energy.

C.It makes our ecosystem more balanced.

D.It consumes nothing made from chemicals.

2What can we infer from the passage?

A.Like cleaning windows, a well-paid job is usually dangerous.

B.Without humans supervising, Ozmo could have performed better.

C.Ozmo can save 400 hours per building compared to a human cleaner.

D.Ozmo can’t be stopped by obstacles with its advanced system.

3What does the underlined part “the tip of the iceberg” mean?

A.A small part of a big plan.

B.As cool as the iceberg.

C.The most advanced technology.

D.The leading role in the modern world.

4What is the best title for the text

A.Robots make a difference.

B.Meet Ozmo, the window cleaning robot.

C.Supervise Ozmo, human safe.

D.Intelligent Ozmo becomes known worldwide.

【题目】 For a single woman, yards are a strange thing. You don’t know whether to buy a lawn mower(割草机)or hire someone to mow it. I did the latter, over many years.

There was one exception. In my early 30sI lived in a cottage near my father, who had a tractor. He lived around the corner on an old country lane, now fully developed. But at the time, it was with sweet relief, having just returned from city life, that I drove his borrowed tractor down the lane in the late afternoon, mowed my land, and then drove it back in the evening light, gazing(注视)up at the stars as they came out.

Soon the routine became impossible with traffic in the developing area. I needed someone to do my yard work.

Vardman was a devoted young boy. He sang at the top of his lungs as he mowed. His work was a joy. But Vardman grew up. After his graduation from high school, which I attended, and his leaving for college, I was without.

So here I was with two African men who brought not only knowledge but a deep love of working the land. There was a peace about the work they did. The perfection was noticeable everywhere, with every border in place, the unnecessary brush cleared out. The rhythm in their work, the rhythm of their work—it was poetry to watch.

Later I moved to North Carolina. I found myself in another small house with a beautiful but wasted yard. A strange mountain man gave me a wonderful price and began what has become an exercise in grace, gratitude and being simple.

Over the few years I have lived here, he has slowly, patiently, lovingly turned a long-neglected place into a quiet beauty. Quiet, modest, sincere, he uses only natural products on the lawn and flower beds. After the growing season ends, he collects his final paycheck and disappears into the mountains. A quiet man is teaching me patience and how it brings beauty back.

1What is the second paragraph mainly about?

A.The development of traffic in the city.

B.The tiredness of mowing down the lanes.

C.The poor living areas in the countryside.

D.The joy of returning home after mowing.

2How did the writer find Vardman?

A.He devoted himself to the job.

B.He was glad to be a mower forever.

C.He wasted the working time by singing.

D.He earned money for his college education.

3Why did the writer mention the poetry in the fifth paragraph?

A.To prove the good job of African mowers,

B.To show her love for African poems,

C.To praise the mowers through writing poems.

D.To describe the images of mowers in poems.

4What did the quiet man teach the writer?

A.Gratitude is a reward for kindness.

B.Money is endless for people to earn.

C.Simple life is worth more paycheck.

D.Beauty comes from working patiently.

【题目】 Most female fashion models start their careers(事业)in their late teens and retire in their early 30s, but 96-year-old Alice Pang isn’t an ordinary fashion model. She started modelling at 93.

Alice always liked dressing well and looking elegant, but never actually considered a career in modelling. But her granddaughter always thought she had it in her, so when she saw an online ad for senior models of 65, she sent in Alice’ s pictures and she was chosen for a photo shoot. Never one to back away from a challenge, Pang decided to give it a shot and even though she knew nothing about modelling, she had all the natural qualities to succeed in it. Today, she is recognized as one of the best senior models in Asia, as well as the oldest.

Born in 1923, Alice never dreamed she’ d one day be modelling for high-end fashion brands like Gucci, Ellery or Valentino, let alone at age 96. But her wonderful skin color and excellent posture(姿势)—uncommon qualities for people of her age—make her one of the most sought-after senior models in the business.

Surprisingly, Alice doesn’t credit exercise or a strict diet for her enviable figure and posture. Even though she agrees that exercise helps some people stay in good shape, she doesn’t even have a morning exercise routine, crediting her good genes(基因)instead. She says her skin is white because she’ s seldom exposed to the sun and she has a straight back.

While most people praise her for her active lifestyle and the courage to start a whole new career in her nineties, some say she should dress and act according to her age. She chooses to ignore them, though, saying that her personal happiness is all that counts.

1What makes Alice Pang a special fashion model?

A.Her unusually long modelling career.

B.Her being famous worldwide at an old age.

C.Her not retiring from modelling in her early 30s.

D.Her starting the career decades later than normal.

2According to the text, Alice is a person who ________.

A.doesn’t give up easily

B.is quite fond of competing with others

C.doesn’t do anything she is unfamiliar with

D.often dreams of being a professional model

3In Alice’ s opinion, her good shape is ________.

A.completely naturalB.quite unexpected

C.due to her strict dietD.the result of regular exercise

4What can be inferred about Alice from the last paragraph?

A.Active as she is, she is rather stubborn.

B.She always turns a deaf ear to others’ opinions.

C.There are different voices on her present lifestyle.

D.She thinks personal happiness comes before modelling.
