查询词典 Megachile

Megachile desertorum Morawitz is an important pollinator of many endangered species and constructive desert plants in West Erdos Region.

沙漠石蜂 Megachile desertorum Morawitz为多种植物的传粉昆虫，在西鄂尔多斯地区是多种濒危植物和荒漠建群植物的重要传粉者。

There were 22 pollinating insect species belonging to 4 orders and 11 families, among which, native bee species Megachile abluta, M. spissula, Xylocopa valga, Andrena parvula and Anthophora melanognatha were the main pollinators. M. abluta, M. spissula and X. valga were of uni-peak type with diurnal foraging activities trom 11:30 to 15:30, while A. parvula and A. melanognatha were of double-peak type with diurnal foraging activities on 9:30-11:30 and 16:30-18:30, indicating a complementary relationship among the pollinators. The main pollinators had significant differences in their tripping frequency and landing time, and their foraging behaviors were correlated with their body sizes.

结果表明：苜蓿访花昆虫共计22种，分别属于4个目，11个科，根据弹花效率初步确定鳞地蜂、黑颚条蜂、净切叶蜂、细切叶蜂和紫木蜂为河西地区主要传粉昆虫；主要传粉昆虫的日活动规律出现单峰型和双峰型2种，净切叶蜂、细切叶蜂和紫木蜂属于前者，只在11：30-15：30出现一个活动高峰，而鳞地蜂与黑颚条蜂则为双峰型，在9：30-11：30和16：30-18：30分别出现访花高峰，不同的传粉昆虫之间存在互补关系；主要传粉昆虫的弹花频率和小花停留时间存在显著差异，且访花行为与野生蜂体型紧密相关。

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。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
