高二英语上校本作业（三）

For the first time,researchers have discovered that some plants can kill insects in order to get

additional nutrients.New research shows that they catch and kill small insects with their own sticky

hairs near the roots and then absorb nutrients through their roots when the insects are killed and fall

to the ground.

Professor Mark Chase,of Kew and Queen Mary,University of London,said,“The cultivated( 培

植的) tomatoes and potatoes still have the hairs.Tomatoes in particular are covered with these sticky

hairs.They do trap small insects on a regular basis.They do kill insects.”

The number of these carnivorous plants is thought to have come up to 50 percent and many of

them have until now been wrongly regarded as among the most harmless plants.Among them are

species of petunia(矮牵牛),some special tobacco plants and cabbages,some varieties of potatoes and

tomatoes,etc.Researchers at Royal Botanical Gardens,Kew,which carried out the study,now believe

there are hundreds more killer plants than previously realized.

It is thought that the technique was developed in the wild to get necessary nutrients in poor

quality soil—and even various plants grown in your vegetable garden still have the ability.

The researchers,publishing their finding in the Botanical Journal of the Linnean

Society,said,“We may be surrounded by many more murderous plants than we think.”“We are

accustomed to thinking of plants as being immobile and harmless,and there is something deeply

frightening about the thought of meat-eating plants,”they added.

25Tomatoes and potatoes kill insects to 　　　.

.get more sticky hairs
