We often think of agriculture as planting seeds and harvesting crops. But many crops do not come from seeds. Many kinds of trees and plants are grown from【C1】________ cut from existing trees and plants. This is called grafting (嫁接).
Farmers cut branches or young growths, called【C2】________, from one plant and place them on a related kind of plant. The branch or bud that is grafted is called a scion (接穗). The plant that【C3】________ the graft is called the root stock. Over time, the【C4】________ from the two plants grow together. The grafted plant begins to【C5】________ the leaves and fruit of the scion, not the root stock.
A graft can be cut in several ways. A cleft graft (割接,劈接), for example, requires a scion with several buds on it. The bottom of the scion is cut in the【C6】________ of the letter V. A place is cut in the root stock to accept the scion. The scion is then【C7】________ placed into the cut on the root stock. Growth medium is put on the【C8】________to keep it wet and help the growth.
Grafting can join scions with【C9】________ qualities to root stock that is strong and resists disease and insects. Some common fruit trees such as sweet cherries have to be grafted.
In an age of high-tech agriculture, grafting is a low-tech method that remains 【C10】________ important.
A) accepts F) desirable K) pieces
B) agreeable G) extremely L) produce
C) blossoms H) grow M) relatively
D) buds I) joint N) securely
E) composes J) parts O) shape [br] 【C3】
选项
答案
A
解析
动词辨析题。空格位于that引导的定语从句,作从句的谓语,主语是plant,所以此处应填第三人称单数形式的谓语动词。上文“The branch or bud that is grafted is called a scion(接穗).”谈的是“嫁接的母体”,这句讲的是“被嫁接体”,应为“接受”嫁接,故A)accepts为本题答案。
