Imagine a classroom missing the one thing that’s long been considered a necessary part to reading and writing---paper. No notebooks, no textbooks, no test papers. Nor are there any pencils or pens, which always seems to run out of ink at the critical moment. A “paperless classroom” is what more and more schools are trying to achieve .

Students don’t do any handwriting in this class . Instead , they use palm size , or specially—designed computers. The teacher downloads texts from Internet libraries and sends them to every student’s personal computer. Having computers also means that students use the Web. They can look up information on any subject they’re studying from maths to social science.

High school teacher Judy Herrell in Florida, US, described how her class used the Web to learn about the war in Afghanistan over one year ago. We could touch every side of the country through different sites from the forest to refugee camps, she said .“Using a book that’s three or four years old is impossible.”And exams can go on line too. At a high school in Tennessee, US, students take tests on their own computers. The teacher records the grades on the network for everyone to see and then copies them to his own electronic grade book. A paperless classroom is a big step towards reducing the waste of paper. High school teacher Stephanie—Sorrell in Kentucky,US, said she used to give about 900 pieces of paper each week to each student.

“Think about the money and trees we could save with the computers,”she said .But, with all this technology, there is always the risk that the machines will break down. So , in case of a power failure or technical problems, paper textbooks are still widely available for these hi—tech students.

1.What does the part of the last sentence in the first paragraph “run out of ink at the critical moment” mean ?

A.Pens may not write well at the critical moment.

B.Pens get lost easily , so you may not find them at the critical moment.

C.Pens may have little or no ink at the critical moment

D.Pens use ink, while pencils don’t.

2.The high school teacher, Judy Herrell, used the example of her class to show that ________.

A.the Web could take them everywhere

B.the Web taught them a lot.

C.the Web is a good tool for information.

D.the Web , better than the textbooks ,can give the latest and comprehensive information.

3.The paperless classroom will benefit _________ the most.

A.students          B.teachers          C.trees             D.computers

4.What does the phrase in the last paragraph “break down ”mean ?

A.Break into pieces   B.Stop working       C.Fall down          D.Lose control

 

【答案】

1.C

2.D

3.C

4.B

【解析】

1.推斷題。從第一段可知,鋼筆有時候在關鍵時刻總是沒有什么墨或是沒有墨水,故選C

2.細節題。從第二段斷尾及We could touch every side of the country through different sites from the forest to refugee camps,可知舉這個例子是說明網站比書本好,因為書本不可能用三四年,而且它還能夠得到最新的,最全面的信息,故選D

3.細節題。從A paperless classroom is a big step towards reducing the waste of paper. High school teacher Stephanie—Sorrell in Kentucky,US, said she used to give about 900 pieces of paper each week to each student.可知無紙化的教室最有助于減少紙的損耗,故選C

4.推斷題。從文章in case of a power failure or technical problems,可知萬一是沒電了或是技術問題,所以此處的短語意思是停止工作的意思,故需B

考點:科普類說明文

點評:本文文脈清晰,結構很好把握。說明文是歷年高考很常見的文體,對于科技類的說明文比較難,而對于說物的文體較容易。本文中,把握好一個中心即對無紙化課堂的介紹。同時,此類文章細節題居多,在對文章看懂了的基礎在仔細對比選項和文章,即可得出答案。

Few of us make money by losing sleep.But three graduate students at Brown University in Providence built a company around sleep deprivation (睡眠不足).

       Jason Donahue, Ben Rubin and Eric Shashoua were working late nights in Brown's business and engineering schools.They began thinking about ways to sleep better.They discovered they weren't alone in burning the midnight oil.Around 20% of Americans get less than six hours of rest a night.

       The friends imagined a smart alarm clock that could track how much time people spend in the most restorative (有回復作用的) stages of the sleep cycle: REM (rapid eye movement) and deep sleep.What would it cost to design such a thing? Five years of research, 20 employees, $14 million and a whole lot of doubting from investors and scientists.

       Their company, Zeo, based in Newton, Mass, launched its product in June, 2009.The Zeo device uses a headband with tiny sensors (傳感器) that scan your brain for signs of four sleep states- REM, light, deep and waking sleep.The smart alarm clock displays a graph of your sleep pattern and wakes you as you're not in REM sleep (which is when you're least groggy).In the morning you can upload the data to the company's Web site, and so track your sleep over time.Most of the feedback comes in the form of Zeo's ZQ score showing how well you've slept.

       "Zeo allows people to unlock this black box of sleep," says Dave Dickinson, a health-care CEO.

       Whether any of this actually improves sleep is up to the consumer, who will also need to make lifestyle changes like cutting out alcohol before bedtime or caffeine after 3 pm.

       For now the company is selling Zeo online only.Dickinson also plans to spread it to countries such as Australia, where sleep deprivation approaches US levels.

Who will support Zeo?

       A.People full of imagination.          B.People suffering sleeping problems.

       C.People having access to the Internet. D.People having bad lifestyles.

Why did the three graduate students imagine a smart alarm clock?

       A.To wake them up on time in the morning.

       B.To earn enough money for their study.

       C.To improve the quality of people's sleep.

       D.To enjoy their life while working at night.

To design the Zeo device, the three graduate students ____.

       A.spent much time and money           B.were widely supported by scientists

       C.worked by themselves all the time       D.attracted many investors

What can we know from the passage?

       A.Zeo has a direct effect on users' lifestyles.

       B.It needs more personal efforts to make Zeo function better.

       C.A large quantity of Zeo devices have been sold in Australia.

       D.Consumers can go to the Zeo company to purchase Zeo in person.

  Imagine yourself on a boat looking out at the horizon and all you can see is the water meeting the sky with no land in sight and you are sailing straight ahead to meet the world. Jesse Martin does not have to imagine: he is living in it.
On Dec. 7, 1998, at 17 years old, Jesse set sail from Melbourne, Australia on his boat, attempting to become the youngest person to sail alone and nonstop around the world. He sailed south of New Zealand, through the South Pacific, around South America, north on the Atlantic, back south past Africa, through the Indian Ocean and back to Melbourne.
Even as a young child, Jesse had been an adventurer who traveled all over Europe and Asia with his parents. Born in Munich, Germany in 1981, he moved to Australia with his family when he was only two years old. They moved close to a rainforest in Cow Bay, about 3500kms north of Melbourne, where they built a small house with no electricity or running water. Jesse grew up at the beach enjoying the outdoors to its fullest.
At 14, he sailed for the first time with his father and brother, Beau. It was after this trip that he began to dream about sailing around the world.
Jesse’s family played an important role. “I was made to believe I could do anything.” he says. Although, he says, there were others that were not so encouraging or supportive, “People that I looked up to, respected and trusted told me I couldn’t. Thankfully, I trusted myself. There were people that said that the boat couldn’t be ready by the time I had to leave.” However, through perseverance and belief in himself he was able to do what many told him was impossible.
On Oct.31, 1999, more than 10 months after he set sail, Jesse Martin went down in history as the youngest person to sail around the world alone, nonstop and unassisted.
【小題1】 What’s the author’s purpose in encouraging the reader to imagine a sailing experience?

A.To show how difficult it is to be a sailor.
B.To show how wonderful Jesse’s sailing is.
C.To describe what Jesse’s sailing is like.
D.To describe what a sailor’s life is like.
【小題2】 Jesse Martin was at the end of his voyage when he _______.
A.sailed on the South Pacific.
B.sailed on the Indian Ocean.
C.sailed past Africa
D.sailed past South America.
【小題3】 Which of the following made Jesse decide to sail alone around the world?
A.His childhood adventure experiences.
B.His journeys to Europe.
C.His first sailing trip with his family.
D.His love for outdoor activities.
【小題4】 What can we learn from Jesse Martin’s story?

B
Shopping carts are such a ubiquitous presence in stores today that it is hard to imagine a time without them.And yet it wasn’t until the year 1937 when the first shopping cart was introduced.
The shopping cart was the brainchild of Sylvan Goldman,the owner of a grocery food chain in 0klahoma.Goldman noticed that his customers struggled to carry their food in heavy hand-held baskets.He decided there must be an easier way for his costomers to carry the food around in his supermarkets.Observing a folding chair, Goldman decided to use that as the prototype for his new shopping cart.
With the aid of a mechanic, Fred Young ,Goldman designed the first shopping cart based on the folding chair.Wheels were placed where the bottoms of the chair legs were. In place of the chair seat, Young and Goldman , placed two metal baskets on top of each other. This cart could be stored by folding it up like a folding chair.
At first there was a bit of difficulty getting the public to accept shopping carts.Men thought using them was effeminate(女人氣的)while younger women considered the use of the shopping carts to carry products around to be somewhat unstylish.Goldman solved this problem by hiring men and women models to use shopping carts in his stores.In addition,store     greeters instructed customers in how to use the shopping carts.In short order,the shopping carts became incredibly popular because it made shopping much easier for customers.By 1940 the popularity of shopping carts had grown to such an extent that there was a 7 year waiting list in store orders for new shopping carts.
45.. The underlined word“ubiquitous”is closest in meaning to”_________”.
A.strange    B.pleasant       C.common       D.possible
46.. The idea of shopping carts came from _____________.
A.Goldman’ s imagination           B.customers’needs
C.Fred Young’ s suggestion           C.other shops’examples
47.. Why was it difficult to get the public to accept shopping carts at first?
A.Both men and women were afraid they would not look good if they used them.
B.  People thought it unnecessary to use them because they never did much shopping.
C.  The early shopping carts were too difficult to use.
D. Only men and women models were supposed to use such modern things.
48.. How popular did Goldman’s invention finally become?
A.Men and women models used shopping carts in his stores.
B.Store greeters instructed customers in how to use the shopping carts.
C.Some stores had to wait several years to get his shopping carts.
D.His shopping carts had improved so much that both men and women liked to use them.
