Every year, malaria （疟疾） sickens about five hundred million people. More than one million of them die, mostly young children and pregnant women in Africa.

For several years in sub-Saharan Africa, the Global Fund and other groups have been paying for bed nets treated with long-lasting insect poison. Malaria is spread by mosquito bites. The groups have also invested in ant malaria drugs for A.C.T., artemisinin-based combination therapy.

Recently, a team from the World Health Organization visited Ethiopia, Ghana, Rwanda and Zambia. These countries were the first to distribute the bed nets and medicine. The Global Fund to Fight AIDS, Tuberculosis（肺结核）and Malaria requested a study to see if the interventions were helping.

The researchers found that the answer is yes. They looked at records of children under five. They found that malaria deaths fell by sixty-six percent in Rwanda between two thousand five and two thousand seven. Deaths fell by fifty-one percent in Ethiopia, thirty-four percent in Ghana and thirty-three percent in Zambia.

The team reported that limited supplies of bed nets could help explain the more limited effects in Zambia and Ghana. But the findings in Ghana were more difficult to explain, because deaths from causes other than malaria fell more sharply. The report says this was in keeping with general improvements in health services.

The full report can be found at who. int, on the page for the global malaria program.

In another new study, researchers reported that vitamin A and zinc treatments might also help protect young children from malaria. Scientists in Burkina Faso found that malaria rainfection rates fell by thirty – four percent in a group of children treated with vitamin A and zinc.

The findings appear in Nutrition Journal, an open access publication that can be read free of charge at nutrition. com.

Roslyn Hing School on long Island recently started a pilot program using iPads in some classrooms.

A growing number of schools across the U.S.are multimedia,history through gamse and math with step-by -step animation(动画）of complex problems.

As part of a pilot program,Roslyn High School handed out 47 iPads on Dec.20,2010 to the students and teachers in two humanities(人文学科）classes. The school district hopes to provide iPads eventually to all 1,100 of its students.

The iPads are to be used in class and at hom during the school year to replace texbooks,allow students to correspond with teachers and tum in papers and homework tasks,and preserve a rocord of student work in digital files.

“It allows us to extend the classes beyond these four walls.”said larry Reiff,an English teacher at Roslyn who now posts all his course mateials online.

But educators are still divided over whether practices to give every student a laptop have made a difference academically.

“Thre is very little evidence that kids learn more,faster of better by using these machines,”said Larry Cuban,a retried professor of eduction at Staford University.“IPads are excellent tools to attract kids,but then the fieshness wears off and you eget int hard-core problems of teaching and learning.”

But school leaders say the iPad is not just a cool new toy but rather a powerful and multifunctional tool with a number of applications,including thousands with educational uses.

“If there isn't an application that does something I need ,there will be sooner or later,”said Mr.Reiff,who said he now used an application that includes all of Shakespare's plays.

1.The program of using iPads in class is            .

A．widely accepted by most schools in the United States

B．only an experimental one carried out in some schools

C．a compulsory one carried out by the U.S government

D．encouraged and organized by the iPad company

2.The underlined part “these four walls”in paragraph 5 refers to    .

A．school dormitory	B．school campus
C．teacher's office	D．school classroom

3.We can use iPads to do the following at school except     .

A．replace the school textbooks	B．keep digital record of homework
C．judge the teachers'teaching	D．communicate with teachers

4.The school leaders tink highly of the iPad mainly because it is       .

A．cool and interesting	B．powerful and helpful
C．multifunctional and expensive	D．attractive and vivid

5.We can infer from the passage that     .

A．most old teachers are against the pilot program

B．students have achieved a lot after using iPads

C．teaching will become less important with the help of ipads

D．iPads will be used is more and more schools in the US
