What’s the best way to protect a tender, green seedling from the hungry stomach of deer? Give the seedling bad breath!
The same chemical that gives people bad breath after they have eaten garlic can save small trees from being eaten by animals.
A kind of chemical selenium(硒), which is also found in garlic, is planted in the soil near a young tree. The tree’s roots absorb the selenium which is then carried to the leaves.
From there the selenium is used to form a chemical called dimethyl selenide (乙烷硒化物)—the same chemical made in the human mouth after eating garlic. As deer wander around looking for food, they smell the seedlings’ leaves and leave the plants alone.
The selenium is important. Why? Because each year deer eat millions of dollars’ worth of trees farm seedlings.
So far, selenium has been tested only on Douglas fir (枞树) seedlings, but researchers think they could protect fruit trees and garden plants, too.
61. When people eat garlic, ________.
A. they send out a horrible smell B. they are out of breath
C. they will feel sick D. it is hard for them to breathe
62. According to this passage the bad smell given off from those leaves is that of ______.
the young trees absorb garlic
the roots of the young trees smell like garlic
the young trees aren’t fit for the deer to eat
the leaves of the young trees smell like garlic
64. Up till the time the news was announced, this kind of chemical was used _______.
A. all over the world B. all over the United States
C. on fruit trees and garden trees D. on Douglas fir young trees
65. The best title of this passage is ________.
A. Hungry Deer and Young Trees B. Why Don’t Deer Eat Young Fruit Trees
C. Plants Saved by “Bad Breath” D. How to Protect Young Trees

答案和解析
为保护脆弱、嫩绿的树苗免遭饥饿的驯鹿吃掉,有什么最好的办法呢?让树苗产生口臭!
人们吃完大蒜后会有口臭,同样的化学物质也可以拯救小树苗免遭动物的嗜食.有一种化学物质硒,也可以从大蒜提取出来,把它埋到小树苗附近的泥土里,树根吸收了硒以后会传送到叶子上.从硒那里往往会反应形成一种乙烷硒化物——一种与人类吃完大蒜后口腔产生的口臭同样的化学物质,当驯鹿们在转悠觅食的时候,闻一下树叶就会开溜了.硒这么重要,为什么呢?因为驯鹿每年会吃掉树苗场价值上千万美元的树苗.
目前为止,硒只是在枞树树苗上测试使用,但研究者认为它们也可以使用在果树和园林植物上.
61、当人们吃大蒜( A )
A、他们发出恐怖的味道 B、他们没有口臭了
C、他们会不舒服 D、他们会呼吸困难
62、根据本文,从树叶发出难闻的味道是( D )
A、小树苗吸收了大蒜 B、小树苗的根闻起来像大蒜
C、小树苗不符合驯鹿的胃口 D、小树苗的叶子闻起来像大蒜的味道
64、直到本文信息公布之时,硒这种化学物质用在( D )
A、全世界 B、全美国
C、果树和园林植物上 D、枞树树苗上
65、本文最佳标题是( C )
A、饥饿的驯鹿和小树苗 B、驯鹿不吃小树苗的原因
C、“口臭”拯救了植物 D、如何保护小树苗
