【題目】 The rapid growth in skyscrapers worldwide has led to a high demand for window washers since most of these buildings feature large glass panes (窗格) to highlight their breathtaking views.

Though the job offers a handsome salary, dangling alongside multi-story structures is dangerous, and accidents are not uncommon. However, if Israel-based company Skyline Technologies has its way, the dangerous chore may soon be taken care of by Ozmo, an intelligent window cleaning robot.

"As a society, we've become too comfortable watching people hanging off the sides of 30-story buildings," says Yaron Schwarez, co-founder and CEO of Skyline Robotics. "No salary could justify allowing people to put their lives in the hands of a system of ropes."

Much like humans, Ozmo is placed on platforms suspended from the buildings and uses its arms and brushes to clean the dirt on the glass panes. A 3D map of the building's surface programmed into its system allows the robot to skillfully handle obstacles as it moves up and down the structure. Computer vision and touch sensors enable it to move out of the way in case of unexpected events, such as the sudden opening of a window.

Unlike current window washers, the robot cleaner does not require soap to clean the glass. Instead, it uses distilled water (蒸餾水) and a process called dirt absorption to do the job. Schwarez explains, "We use pure water to absorb and remove the salts, the minerals, the oils, and the dirt from the building. We are environmentally-friendly."

Ozmo is also expected to be much more efficient than humans. While it currently takes three cleaners 480 hours each to clean the windows of a 40-story glass building, the robot will single-handedly complete the task in just 80 hours. However, unlike other robots, Ozmo will not replace human workers. It will only make their jobs safer by lifting them to the role of supervisors, who will be remotely controlling the operation from below.

Whether Ozmo, which is still undergoing testing, does as good a job as human remains to be seen.

【1】Which of the following can best replace the phrase "has its way" in paragraph 2?

A.Succeeds.B.Hesitates.

C.Struggles.D.Exists.

【2】What can we learn about Ozmo from the passage?

A.It requires chemicals to clean.

B.It has trouble crossing obstacles.

C.It operates with great efficiency.

D.It works without human helpers.

【3】What is the author's attitude towards the future application of Ozmo?

A.Optimistic.

B.Doubtful

C.Unconceded.

D.Objective.

【4】What is the best tile for the text?

A.Ozmo: a Double-edged Sword.

B.Ozmo: a Smart Window Cleaner.

C.Window Washing: a Dangerous Job.

D.Window Washing: a Blessing in Disguise.

【答案】

【1】A

【2】C

【3】D

【4】B

【解析】

這是一篇說明文。介紹一種能清潔摩天大樓窗戶玻璃的新型機器人Ozmo的工作原理，優(yōu)勢。但是Ozmo是否能像人類一樣發(fā)揮良好的作用還有待觀察。

【1】

詞義猜測題。根據(jù)下文the dangerous chore may soon be taken care of by Ozmo, an intelligent window cleaning robot.可知清洗摩天大樓窗戶這樣的雜事可以由該公司的智能機器人來做，因此可知該公司的這項技術(shù)應(yīng)該是成功的。故選A。

【2】

細節(jié)理解題。根據(jù)倒數(shù)第二段Ozmo is also expected to be much more efficient than humans. Ozmo也被認為比人類的效率更高。While it currently takes three cleaners 480 hours each to clean the windows of a 40-story glass building, the robot will single-handedly complete the task in just 80 hours.可知相對人工清理一棟40層樓的玻璃建筑，人工需要480小時，而該機器人僅需80小時。可知 Ozmo 的工作效率很高。故選C。

【3】

推理判斷題。根據(jù)倒數(shù)第二段Ozmo is also expected to be much more efficient than humans.可知作者認為該機器人能大大提高效率，然而卻不能完全取代人工清潔。 根據(jù)最后一段Whether Ozmo, which is still undergoing testing, does as good a job as human remains to be seen.目前仍在測試中的Ozmo是否能像人類一樣發(fā)揮良好的作用還有待觀察。由此判斷出作者對Ozmo未來的應(yīng)用持客觀的態(tài)度。故選D。

【4】

主旨大意題。根據(jù)第二段最后一句However, if Israel-based company Skyline Technologies has its way, the dangerous chore may soon be taken care of by Ozmo, an intelligent window cleaning robot，然而，如果以色列公司天際線技術(shù)(Skyline Technologies)能夠成功的話，這種危險的家務(wù)可能很快就會由智能窗戶清潔機器人Ozmo來處理。以及下文對于對于 Ozmo的工作原理，優(yōu)勢的介紹。可知，短文的最佳標(biāo)題為“Ozmo：智能窗戶清洗工”故選B。

把握文章的主旨大意主要有三種方法：

1.找準主題句，如本題的主題句在第二段的最后一句。

2.看文章篇幅主要在講什么。

3.根據(jù)選項標(biāo)題逆向推理文章可能會說些什么，如果和文章內(nèi)容不匹配的不能選。

根據(jù)第二段最后一句However, if Israel-based company Skyline Technologies has its way, the dangerous chore may soon be taken care of by Ozmo, an intelligent window cleaning robot，然而，如果以色列公司天際線技術(shù)(Skyline Technologies)能夠成功的話，這種危險的家務(wù)可能很快就會由智能窗戶清潔機器人Ozmo來處理。以及下文對于對于 Ozmo的工作原理，優(yōu)勢的介紹�？芍�，短文的最佳標(biāo)題為“Ozmo：智能窗戶清洗工”故小題4選 B 。

【題目】 Recently, as I watched my son Nathan play basketball for his high school team, I started to feel sorry for myself and for him. His team was facing adversity (逆境) — it was the opponent’s home gym filled with their supporters, and Nathan’s team was left behind for three quarters of the game.

As for me, I had been fired earlier in the day. I was prepared for it as I had experienced the same thing 14 years earlier, but, just like a punch in the mouth, the blow is never softened because you were expecting it.

As I watched the adversity on the court that my son was experiencing, I recalled my earlier events, packing up everything in a box and waving goodbye to a great group of colleagues with whom I’d had the pleasure of working. During my driving home, I kept telling myself “Just like that time, I will find work again in a short time—I am confident in my experience and abilities.” It was the same belief that I tried to teach my son.

The basketball game entered the fourth quarter with Nathan’s team still trailing. As Nathan and his teammates fought back, I saw the focus and determination on him, as well as his teammates’faces. Then, with a tie game and seconds on the clock, Nathan found himself with the ball. There was no room for self-doubt. With skill and confidence he was able to tune out all that could drive his attention away and make the throw as if he had done it a thousand times. The joy on his face, the cheering from the crowd, and the silence on the other side of the gym—it was a moment that would make any parent proud.

As I sat there, my heart bursting with pride, it dawned on me that I had taught him determination in the face of adversity, and he had just taught me the same lesson. That brief moment of self-doubt and feeling sorry for myself was blown away by the actions of my son on the basketball court. He will play in the finals, but it doesn’t matter if he wins or loses, at this moment.

【1】What did the author intend to show by mentioning his experience 14 years ago?

A.He quit a job again.B.He disliked working with the colleagues.

C.He made a right career choice.D.He had confidence in his abilities.

【2】What can we infer from the passage?

A.Nathan’s teammates couldn’t focus on the play.

B.The author was never worried about his son’s team.

C.Nathan’s team lost the game at last.

D.The game was in a tie at one time.

【3】What is the passage mainly about?

A.A blow from losing a job.B.A lesson on the court.

C.The importance of teamwork.D.The rise and fall of a game.

【題目】 Even if you don't know much about Russian author Maxim Gorky (1868-1936), you may be familiar with his famous poem The Song of the Stormy Petrel since its ending note “Let it break in all its fury!" has been encouraging generations of people for years now.

Gorky was a highly influential author. More than any other writer, he laid the foundations for the famous literary style known as socialist realism. In this kind of writing, the author uses literary techniques to create the impression of reality in his or her writings.

March 16 this year marked the 152th anniversary of Gorky's birth.

He was born into an ordinary life but soon became an orphan, before being raised by his grandmother in poverty. As he grew older, he would take a job and then quickly move on to another. He tried many jobs, but the one that he seemed to love the most was being a journalist.

It was in this job that he gained a particular impression of the world — that it was horribly inequitable in its treatment of the poor. It was a world, therefore, that had to go. Gorky was naturally attracted to the political movement of Marxian social democracy.He knew many revolutionaries including the most important one of all, Vladimir Lenin(1870-1924). The two became friends in 1903 and The Song of the Stormy Petrel was one of Lenin's favorite works by Gorky.

Asa writer, Gorky naturally valued literature. But lie also valued life experience, of which he had plenty. The key to being a modem person, he thought, was to acquire a critical attitude: “Keep reading books, but remember that a book's only a book, and you should learn to think for yourself,” he once said.

【1】What can we learn about Gorky's childhood?

A.He lived an extraordinary life.B.He tried few jobs.

C.He led a hard life.D.He grew up by himself

【2】What docs the underlined word "inequitable" in paragraph 5 refer to?

A.Unconditional.B.Unfair.

C.Unreal.D.Unfriendly.

【3】Which of the following is TRUE about Gorky?

A.He valued critical thinking.B.He was of little influence.

C.He was easy to bow before difficulties.D.He discounted life experience.

【4】What is the text mainly about?

A.Gorky and his family.B.The hardship Gorky experienced.

C.Gorky's famous works.D.Gorky's influence in literature and his life.
