在非洲，每年都有大量的大象和犀牛被偷獵?，F(xiàn)在，非洲的科學(xué)家正在利用脫氧核糖核酸（DNA）測(cè)試，將非法販運(yùn)者與被獵殺的大象和犀牛聯(lián)系起來(lái)，以進(jìn)行抓捕，為大象和犀牛保駕護(hù)航。

1 A great number of elephants and rhinos are hunted in Africa every year. Poachers （偷獵者） kill elephants for their tusks and rhinos for their horns to earn money even though it is against the law. Then other people， called “traffickers”， buy the tusks and horns， ship them out of the country and sell them again for even more money.

2 Elephant tusks can sell for about $450 a pound （$1000 a kilogram）. Rhino horns can sell for more than $27，000 a pound （$60，000 a kilogram）. Sometimes the tusks and horns are made into cups， artworks or jewelry（珠寶）. Sometimes they are made into powder， which people eat as medicine.

3 It has been hard to catch the criminals （罪犯）. Usually by the time the dead animals were found， the poachers were far away. Until recently， African scientists are using DNA to help find the criminals and send them to prison. They are using DNA tests to connect traffickers with elephants and rhinos that have been killed. Computers are used to build complete lists of the DNA of almost all of the elephants and rhinos in Africa. These DNA records allow the scientists to build powerful tools for protecting the animals.

4 Now when tusks or horns are found on a ship in another country， DNA tests can show where they come from. This information can lead to quick actions in the country where the animals were killed. With the new DNA information， it is easier to prove that someone has been involved （牽涉） in killing animals for their tusks or horns.

5 So far， these DNA records have been used to send poachers and traffickers to prison in many countries in Africa. People hope that by punishing poachers and traffickers， they can save the lives of more African elephants and rhinos.
