I suppose that having been brought up in the countryside and close  to animals，it wasn’t remarkable(不平常的)when I decided  to become a vet(兽医)．Luckily I was also good at all the necessary science subjects. So after the college entrance examination I found myself at a veterinary college，training to look after animals in all kinds of situations. I hoped that I would be able to work in the research field so that I could find cures for animal diseases.

    Much to my surprise，I found public health care was a very important aspect of my course. This is an area of animal medicine where a vet’s work has many things in common with the work of a doctor of human diseases. I particularly liked it because I recognized that the study of animal diseases can help human medicine. As we know，many infectious diseases come from animals—including SARS and bird flu.

Some of the infections have only been understood after carefully analytical work in labs by animal doctors. They helped identify the animal source for diseases such as SARS. They were also the first to identify various kinds of viruses. Sometimes vets are also able to suggest a cure for human illnesses. When I found this out I was determined to make public health medicine my chosen career.

After graduation，I applied for a job in public health. Soon I found myself concerned with the problem of bird flu. This is  an illness that attacks birds，but humans can catch the disease  if they are in close contact with infected birds. Though the job  is dangerous，it makes me proud that vets and other animal  disease researchers are in the front line helping to fight these  unknown human diseases

Scientists around the world have been studying the warming of waters in the Pacific Ocean known as El Nino （厄尔尼诺）. The appearance of El Nino is known to affect the weather around the world. Scientists still do not completely understand it. Yet they now find they can use it to tell about the future in different areas of the world.

One example is the work of two scientists at Columbia University in New York, Mark Cane and Gordon Eshel. A scientist of Zimbabwe（津巴布韦）, Roger Buckland worked with them. They have found that when El Nino appears, Zimbabwe has little or no rain. This means corn crops in Zimbabwe are poor. The last El Nino was in 1991 to 1993. That was when southeastern Africa suffered a serious lack of rain.

The scientists wrote about their recent work in the publication（出版物）Nature. Their computer program can tell when an El Nino will develop up to a year before it does. They suggest that this could provide an effective early warning system for southern Africa, and could prevent many people from starving.

1.El Nino is known as ___.

A. the changing of the weather in southern Africa

B. the warming of waters in the Pacific Ocean

C. the weather which brings drought（旱灾）to Africa

D. the weather phenomenon（现象）that brings heavy rains to Africa

2.Scientists study El Nino in order that ___.

A. they can provide a kind of early warning to the place that will suffer from drought

B. they can tell why Zimbabwe has little or no rain

C. they can do some research work in this field.

D. they can put all this information into their computers.

B. Three scientists from the USA work on this subject.

C. Southern Africa suffered a serious drought and many people died from hunger.

D. El Nino has something to do with Zimbabwe’s poor crops.

4.Which of the following is NOT true according to the article?

A. The computer is used in this research work.

B. Scientists know when an El Nino appears by means of the computer program.
