[00:04.00]For Questions 6-10,you'll hear a research report on Wildlife Protection

[00:10.84]While you listen,

[00:14.29]complete the sentences or answer the questions.

[00:18.76]Use not more than 3 words for each answer.

[00:23.51]You now have 25 seconds

[00:27.17]to read the sentences and the questions below.

[00:32.03]W:Environmental scientists say

[00:36.96]protecting wildlife and wild places is extremely important

[00:42.92]if the world is to continue to support human life.

[00:47.67]These experts say we must understand the important links

[00:52.74]between ourselves and the wild plants and

[00:57.29]animals in our environmental support system.

[01:01.86]They note that no one knows for sure

[01:06.82]which of these plants and animalsmay be useful to us in the future.

[01:12.18]Through the years,diseases and insects

[01:16.64]develop that can destroy some kinds of plants and animals.

[01:22.29]Farmers then need a new supply of different kinds of plants to grow

[01:28.35]and animals to raise for food and work.

[01:32.81]These new species 2 are found in the wild,or scientists mix genetic 3 material

[01:39.76]from many different species to develop new ones.

[01:44.62]In recent years,scientists have expressed concern

[01:49.66]that almost every coffee tree in Brazil comes from one kind of plants.

[01:56.32]And all soybean plants in the United States come from six kinds of soybeans

[02:02.98]found in one place in Asia.

[02:06.82]The scientists fear

[02:10.17]that a change in weather conditions or an attack by insects or disease 1,

[02:16.33]could destroy Brazil's coffee trees and America's soybean plants.

[02:22.50]This would not happen if we grew different kinds ofcoffee trees and soybean plants

[02:29.76]They would not all be affected 4 by the same weather,insects or disease.

[02:36.03]Scientists also're concerned about the loss of many species of traditional farm animals

[02:43.19]For example,almost 115 of the original 145 kinds of cattle

[02:51.05]in European and the Mediterranean 5 area are in danger of dying 6 out.

[02:57.11]Traditional kinds of farm animals can be very valuable.

[03:02.28]A rare European sheep,for example,

[03:06.44]has been used to produce a kind of sheep that can survive where the weather's very hot

[03:13.52]And it still produces good wool.
