When you watch TV programmes about wild animals.It is amazing to see how an African animal can(41)E a lion's attack.In the wilderness,every one has a stunt (绝技).Even plants have their own ways of fighting off enemies.
Over millions of years of(42)G,plants have developed a unique defence system.Chemicals are widely used for(43)J.By making their leaves,flowers,stems,roots and fruits(44)A or poisonous to animals,plants can fight back.
One such plant is the Golden Wattle tree.British (45)H David Cameron has found when an animal eats the tree's leaves,the amount of poisonous tannin(单宁) increases in the other leaves."It's like the damaged leaves(46)B the others telling them to fight together against the enemy,"he said.
The tree also sends defence messages to neighboring plants by giving out a special smell.Golden Wattle tree in the(47)E 45meters will get the message and produce more tannin within 10minutes.Now,if an animal eats too many of the trees'leaves,it will die.
Every species of plant or tree specializes in the production of a particular set of (48)F.A plant-eating animal that can safely eat the leaves of one tree may be poisoned by its neighbor.
In this way,plants have developed not only(49)C defence systems,but also shared them with others.This makes it impossible for a single animal to destroy even a small area of forest.

10.Children have lost touch with nature and the outdoors in just one generation!Recently a campaign encouraging children to put away (36)B-and play outside has been organized.The campaign,said to be the biggest (37)A,has been launched with the (38)Dof a documentary film,Project Wild Thing.It tells the story of how,(39)D an attempt to get his daughter and son outside,film-maker David Bond (40)B as marketing director for nature.
The call to renew a (41)Awith nature comes from about 400organizations,from
playgroups to the National Health Service.Children are being (42)Cto take back their"wild time",(43)C30minutes of screen use for outdoor activities.The organizers (44)Dthat giving up 30minutes of television and computer games each day in exchange for outdoor play will increase the (45)Bof fitness and alertness and improve children's well-being.
According to the chairman Andy Simpson,right now,time spent outdoors is (46)A,
activity levels are declining and the ability to identify common species has been (47)D"With many more parents becoming (48)C the dominance(统治地位)of screen time in their children's lives,and growing scientific evidence that a decline in (49)B time is bad news for the health and happiness of our children,we all need to become marketing directors for nature.We want parents to see what this magical wonder product does for their kids'development,independence and creativity,by giving wild time a (50)A,"said Mr.Simpson.
In Mr.Bond's opinion,the reasons why kids,(51)D they live in cities or the countryside,have become (52)Bfrom nature and the outdoors are complex."We need to make more space for wild time in children's daily routine,(53)A this generation of kids to have the sort of experiences that many of us took for granted.It's all about finding (54)C on your doorstep and discovering the sights,sounds and (55)B of nature一maybe in a back garden,a local park,or just green space at the end of the road."
