For Americans, a mosquito bite is an itchy bother. But for many in Africa, a tiny bite can be deadly. One million people die each year of malaria, a disease spread by infected mosquitoes. Most of these people live in Africa, and are under age 5.

Malaria can be prevented and treated. However, many African nations don't have the funds to fight it. Nothing but Nets (NBN) hopes to change that. The United Nations Foundation created the campaign in 2006. The aim is to prevent malaria by covering sleeping areas with nets. Hanging bed nets treated with insecticide(殺蟲劑) is the simplest way to stop mosquitoes from biting at night. The chemicals last four to five years. For $10, anyone can send a net to Africa and help save a life.

So far, NBN has raised $19 million and delivered 700,000 nets to seven countries. Families are taught how to use the nets. Kids also get vaccines (疫苗)and vitamins. "Women line up for miles to get the medicine for their kids," says NBN director Elizabeth McKee Gore. "They understand the importance."

So do kids in this country. "They get so excited thinking of ways to raise money," says NBN spokesperson and basketball star Ruth Riley.

NBN's biggest fund-raiser is Katherine Commale, 7. She's been spreading the information about bed nets for the past two years. To show how they work, she and her brother made a video. "We teach that bed nets can save lives," she said.

Katherine has raised $42,000 for NBN. "She just wants those who need a net to have one," says her mom, Lynda. "It's pretty simple to her." To find out how you can help, visit nothingbutnets.net.

We know from the passage that NBN is in fact _________.

   A. a deadly disease                B. an organization

   C. a piece of equipment            D. a game

The purpose of the passage is most probably ___________.

   A. to list the sufferings of the African people

   B. to introduce new ways to avoid mosquito bites

   C. to call on people to offer their help to Africans

   D. to tell people how to buy nets in Africa

By saying “So do kids in this country” in Paragraph 4,the author means that kids in this country also ___________.

   A. know the importance of the bed nets

   B. know how to protect themselves

   C. lack nets to protect themselves

   D. suffer from malaria

What do we know about Katherine from the passage?

   A. She set up the website nothingbutnets.net.

   B. She is the youngest money-raiser for NBN.

   C. She raised money by making and selling videos.

   D. She started working for NBN at the age of 5.

 (衡陽市八中2008屆高三模擬試題B篇)

Skipping classes, particularly big lectures where an absence is likely to go undetected, is a tradition among college undergraduates.

These days, however, some professors say they’re seeing more absenteeism, as students make the most of new technologies as learning aids.

Americ Azevedo taught an “ Introduction to Computers ” at the University of California, Berkeley, US last semester. By visiting the course’s website, the 200 enrolled students could download audio recordings or watch digital videos of the lectures, as well as read the instructor’s detailed lecture notes.

But there was one big problem: So many of the undergraduates relied on the technology that at times only 20 or so actually showed up for class.

Doug Suda, 19, a student in Azevedo’s class last semester, said he skipped about three-quarter of the lectures. It’s largely because he was busy with an off-campus job and was taking the course to fulfill a business major requirement.

At the end of the term, Suda prepared hurriedly for the final exam by watching videos of about 15 lectures over three days.

“ If I hadn’t that… I would probably fail the class,” said Suda, who instead received a B-plus.

Despite the concerns about absenteeism, schools are increasingly experimenting with ways to let students watch or listen to lectures on their computers or digital music players, like ipods. Last month, Harvard Medical School began “ Podcasting ”lectures. Students can download them into digital musical players, and study while they, say, go for a walk.

As many academics accept the electronic innovation, others are pushing back. To encourage attendance, they are applying low-tech tactics, like giving more surprising quizzes or cutting back their online offerings.

Lee Chanian, a UCLA economics professor, says “ too much technology leads to passive learning environment and encourage more absenteeism”. He now puts fewer lecture materials online, and provides extensive notes only for the most complicated topics.

60.The word “ absenteeism ” in the 2nd paragraph most probably means      .

A. attending classes                B. having classes

C. giving classes                   D. skipping classes

61.At times only 20 or so undergraduates showed up for Americ Azevedo’s class because     .

A. so many undergraduates relied on digital learning aids 

B. so many undergraduates have off-campus jobs.

C. his lectures were boring               D. the exam was easy to pass

62.According to the passage, to encourage attendance, some academics are applying the following lower-tech tactics EXCEPT     .

  A. giving more surprise quizzes          

B. putting fewer lecture materials online

C. providing extensive notes only for the most complicated topics 

D. cutting off their online offerings

63.What could be the best title for this passage?

A. Lectures fight digital learning aids to up class numbers   

B. Lectures apply digital learning aids to up class numbers

C. Lectures fight lower-tech tactics to up class numbers

D. Schools are encouraging more absenteeism
