简介：英语学习者们对于＂toraincatsanddogs＂这个习语的意思都比较熟悉,就是指＂下倾盆大雨＂（rainveryheavily）,但关于它确切的起源却是无从考证。下面谈到的是几种流传比较广的说法。传说在古老的伦敦,当时人们使用的排水系统非常简陋,排水能力极其有限,一场倾盆大雨后往往就是一片狼藉,淹死许多的狗和猫。因此,雨停水退后,满街都是死狗死猫,似乎天上落下来的一样。

简介：“Toraineatsanddoge”的意思大家可能都知识是“下倾盆大雨”，但是有人可能就要问了为什么英语中用“catsanddogs”来形容雨下得大，而不是“hippopotami”（河马），“elephants”（大象），“buckets”（水桶）之类的东西。

简介：AbstractIn this study, we explored the viral diversity and community structures of the ticks collected from dogs and detected possible tick-borne viruses (TBVs) using metagenomic analysis. Additionally, full-length sequences and the structural, phylogenetic and molecular features of the possible TBVs were characterized using bioinformatics tools. The sequence run produced 12,254,268 reads and 6,667,259 unique reads from the tick pools. Further analysis of the viral reads revealed that 92.73% were similar to ssRNA viruses, and 90.5% of the total viral sequences belonged to Non-classified viral families. Of the 29 classified viral families, most virome sequences were homologous with vertebrate viruses from Circoviridae, plant viruses from Virgaviridae, phages from Microviridae, insect viruses from Baculoviridae, and giant viruses from Mimiviridae. In the process of assembly of reads, large contigs representing four virus families were identified, including Phenuiviridae, Chuviridae, Parvoviridae and Non-classified families. Some sequences of Non-classified family shared a highly divergent amino acid sequence identities from existing virus sequences. The importance of these newly identified virus contigs to public and veterinary health needs additional researches. Because of the lack of the acquired viral reads from these families, we only demonstrated the complete sequences of Circoviridae in detail. The complete canine circovirus (CaCV)-NC21 genome detected from police dogs was 2,063 bp long with a GC content of 53.6%. Our results suggested that tick viromes collected from dogs contained diverse sequences with a broad range of animal, insect, plant, and phage viruses, which may reflect the ecological characteristics of the dogs and their ticks. Furthermore, our study revealed the existence of the partial contigs belonging to the four virus families in ticks. More researches are needed to verify their importance to public and veterinary health. As well, our detection of CaCv-NC21 demonstrated that ticks can harbor and potentially transmit canine circoviruses.
