The World Health Organization says as many as 10 million persons worldwide may have the vi
rus(病毒) that causes AIDS. Experts believe about 350 thousand persons have the disease. And one million more may get it in the next five years. In the United States, about 50,000 persons have died with AIDS. The country's top medical official says more than 90 percent of all Americans who had the AIDS virus five years ago are dead.

There is no cure for AIDS and no vaccine(疫苗) medicine to prevent it. However, researchers know much more about AIDS than they did just a few years ago. We now know that AIDS is caused by a virus. The virus invades healthy cells including white blood cells that are part of our defense system against disease. It takes control of the healthy cell's genetic(遗传的) material and forces the cell to make a copy of the virus. The cell then dies. And the viral particles move on to invade and kill more healthy cells.

The AIDS virus is carried in a person's body fluids. The virus can be passed sexually or by sharing instruments used to take intravenous(静脉内的) drugs. It also can be passed in blood products or from a pregnant woman with AIDS to her developing baby.

Many stories about the spread of AIDS are false. You cannot get AIDS by working or attending school with someone who has the disease. You cannot get it by touching, drinking glasses or other objects used by such persons. Experts say no one has gotten AIDS by living with, caring for or touching an AIDS patient.

There are several warning signs of an AIDS infection. They include always feeling tired, unexplained weight loss and uncontrolled expulsion of body wastes(大小便失禁). Other warnings are the appearance of white areas on the mouth, dark red areas of skin that do not disappear and a higher than normal body temperature.

Concerning the ways the AIDS virus can be passed, which of the following statements is wrong?

A.An AIDS mother can pass on the virus to her unborn child.

B.The AIDS virus can be passed on through infected blood.

C.The AIDS virus can be passed on by shaking hands and sharing belongings.

D.The AIDS virus is passed sexually.

Task 2Directions: This task is the same as Task 1.The 5 questions or unfinished statements

Task 2

Directions: This task is the same as Task 1. The 5 questions or unfinished statements are numbered 41 through 45.

Thursday, April seventh, is World Health Day. The World Health Organization recognizes World Health Day each year to increase interest about a health issue it considers of special concern. This year, World Health Day examines the health of mothers and children in developing countries.

The health of mothers and children is this year's World Health Day issue.

The WHO says more than half a million women die every year from problems related to pregnancy(妊娠) and childbirth. Millions more women survive, but suffer disabilities. About eleven million children also die each year, many within the first month of life.

A million or more children are left without mothers each year as a result of women dying from pregnancy-related problems. Experts say these children are three to ten times more likely to die within two years than children who live with both parents.

Most deaths of mothers happen among poor people in developing countries. The highest maternal(母亲的) death rates around the world are in southern African countries, followed by central Asia. Women are most at risk during childbirth in Sierra Leone and Afghanistan. Experts say one out of six women in those countries will die from problems related to pregnancy and childbirth.

WHO officials say most of the deaths result from lack of skilled care during pregnancy and childbirth and lack of clean conditions. Many babies would survive with safe birthing methods, good nutrition, vaccines against disease and good care at home.

The disease AIDS is also an increasing threat to both mothers and their children. Experts say almost half of all adults living with AIDS and the virus(病毒) that causes it are women. And there is increased risk that an infected mother will pass the virus to her baby. Experts say many deaths could be prevented by using medicines during childbirth that prevent mothers from passing the AIDS virus to their babies.

Last year, nations approved Millennium Development Goals for the year two thousand fifteen. They agreed to work to reduce the number of women dying in childbirth by three-quarters. They also promised to reduce the number of child deaths by two-thirds.

Why was the World Health Day recognized by WHO?

A.To increase interest about the health of mothers and children in developing countries.

B.To draw people's attention to a health issue it considers of special concern each year.

C.To prevent deaths of mothers from happening among poor families in developing countries.

D.To warn people the disease AIDS is threatening human beings.
