The three dialogues, Phaedo, Symposium, and Theaetetus, also begin in dramatic form but then proceed to virtually uninterrupted narration by followers of Socrates, and all, apparently, based on their distant memory or secondhand reports.

有三篇对话--《斐多篇》、《会饮篇》和《泰阿泰德篇》，也是始于戏剧形式，但后来实际上是由苏格拉底的追随者进行的连续叙述，这些叙述显然是基于他们遥远的回忆或间接的听说。

As the first key town on the Tea-horse Ancient Road/Route to the west of Chengdu, Pingle is one of the origins of the Ancient Shu civilization.

平乐是一个新兴的旅游古镇。其建镇的历史据说始于西汉年间。川南古道、南丝绸之路都在这座古镇留下了痕迹。至今，古镇西边的骑龙山上，仍保留着当年的一段古驿道。

RESULTS: The dorsal carpal branch begins with ulnar artery (3.9 +/- 1.2) cm above the pisiform with diameter of (1.3 +/- 0.2) mm, and branches off into ascending and descending branches.

结果 尺动脉腕背支于豌豆骨上(3.9±1.2)cm始于尺动脉，外径(1.3±0.2) mm，分出升支、降支。

Female sterility widely existed in plantae. The first report of plant female sterility appeared in the 1950s.

雌性不育现象在植物界广泛存在，有关该类现象的报道始于上个世纪50年代。

At first jiasu expressway starts at jiaxing, 01 provincial highway and the Trans-linear things. 07 provincial highway and river trade routes Zongchuan Jiasu Pottinger North and South. Especially in Hangzhou bridge is built, connecting Shanghai will become the jiaxing, and the Soviet Union, Hangzhou, Ningbo a transport hub.

乍嘉苏高速公路始于乍浦，01省道及其复线横贯东西，07省道和乍嘉苏内河航纵穿南北，尤其是杭州跨海大桥建成之后，嘉兴港区将成为连接沪、苏、杭、甬的一个交通枢纽。

Representation theory of quivers is applied to system theory. As a result, the regular points in system spaces are characterized. Moreover, all prestable points in system spaces are described and another generic property of linear systems is introduced.

解决了始于二十年前的系统空间的正则点的刻画问题，证明了Tannenbaum在1983年提出的&矩阵具有极大秩是正则性的必要条件&这一猜测，纠正了其关于系统空间预稳定点的错误刻画。

Eden, or more prosaically on the savannahs of present-day east Africa, it is clear that Homo sapiens did not start life as an urban creature.

无论认为人类历史始于被称作伊甸园的美索不达米亚地区花园，还是在如今平淡无奇的东非大草原，有一点清楚明白：现代人类起源并不在城市。

WHETHER you think the human story begins in a garden in Mesopotamia known as Eden , or more prosaically on the savannahs of present-day east Africa , it is clear that Homo sapiens did not start life as an urban creature.

无论认为人类历史始于被称作伊甸园的美索不达米亚地区花园，还是在如今平淡无奇的东非大草原，有一点清楚明白：现代人类起源并不在城市。

The girl and Doctor Reefy began their courtship on a summer afternoon.

姑娘和里菲医生的感情始于一个夏天的午后。

Transcriptional activity of ACL recombinants normalized by Renilla was significant difference with pGL3-Basic expect for construct -27 and -15 (P＜0.01). Construct -919 contains highest activity. 3 times reduction of transcriptional activity from-919 to -679bp indicated that negative regulation factors located probably in this region. The activity started on construct -73 suggested the basal promoter activity was located within the -73 to +77bp region; Transcriptional activity of IDHβrecombinants was not significantly different between the recombinant -58 and pGL3-Basic. The activity started on construct -82, decreasing with the length of the fragment up to -164 in despite of a bit of fluctuation, and kept increasing from construct -164 up to -279. Thus, the basal promoter activity was located within the -82 to +16bp region, whereas the upstream 197bp conferred maximal transcriptional activity.

采用5'端缺失策略，结合启动子预测结果，分别构建了8个ACL基因和19个IDH3β基因启动子区重组子，将其转染猪PK15细胞系，并利用荧光素酶双报告基因系统检测了它们的活性，结果表明：在所构建的猪ACL基因5侧翼序列的8个重组子中，除pGL-ACL27和pGL-ACL15外，其它重组子的荧光素酶活性与阴性对照均达到极显著水平(P＜0.01)，表明它们均具有启动子活性，pGL-ACL919活性最强，到pGL-ACL679活性下降了将近3倍，说明从-919bp到-679bp区域可能存在负的调控位点，从pGL-ACL621到pGL-ACL73活性有小幅度下降，到pGL-ACL27活性降到与阴性对照水平无显著差异，表明维持该启动子的基本活性区域位于-73bp到+77bp之间；IDH3β基因启动子活性开始于pGL-IB82，然后虽然有些波动，但是活性一直下降直到-164bp处，之后活性又开始升高，直到-279bp处活性达到最高，这些表明维持该启动子的基本活性区域位于-82bp到+16bp之间，从-82到-279之间的179bp区域具有最高的启动子活性。
