The fused insecticidal protein may delay the process of insects?developing resistance. After investigation of the secondary structure and action mode of Bt insecticidal protein and Cowpea trypsin proteinase inhibitor, as well as the action mechanism of insect enterokinase, we devised the fusion gene on the base of maintaining their functions respectively. The method follows: CpTI gene is linked to 3?-end of GFM crylA gene by a nucleotide sequence encoding cleavage site of insect enterokinase.

根据Bt杀虫蛋白Cry1A和豇豆胰蛋白酶抑制剂的高级结构、杀虫机理及昆虫体内肠激酶的作用机理，本着尽量不影响二者功能的原则，设计出了构建Cry1A和CpTI融合杀虫基因CryCI的方案，即将CpTI基因的编码序列连接到GFM Cry1A基因编码区3'端，并在其间用一段编码肠激酶切割位点的序列相连。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
