语法化 recruit 什么意思
语法化：借以使词汇项和结构进入某种语言环境以表示语法功能的演变，一旦这些词汇项和结构发生了语法化，它们继续发展出新的语法功能。 语法化有两层含义：（1）作为一种用来解释语言现象的研究框架，语法化指关于语言演变研究的部分（如：词汇项和结构是如何进入某种语境来表示语法功能的？语法项是如何发展出语法功能的？）（2）作为一个涉及实际语言现象本身的术语，语法化指借以使特殊项因时间的推移而变得更具语法性的演变步骤。 语法化可以从两个角度进行研究：（1）一个是历时的角度，将语法化视为语言演变的一部分，考察语法形式的来源、形成和发展途径；（2）一个是共时的角度，将语法化视为一种句法和语用现象，考察在日常语言使用中表达语法关系的各种手段。 国内外关于语法化，已达成四点共识：一是语法化的主体是句法化（尤其是实词虚化）、形态化；二是语法化大多是有理据的，有动因、有机制，语言的经济性、像似性、明晰性以及说话者的目的、语用推理等，都是影响语法化的重要因素；三是语法化是渐变的过程；四是语法化是单向性为主的（从实到虚，从比较虚到更虚）。

NF-κB Pathway是什么意思？
NF-κB信号传导在生物学角度是这样解释的。这里给大家解释一下：Nuclear factor kappa beta (NF-kB) is a nearly ubiquitous pathway responsible for mediating DNA transcription, and thereby cell function. The pathway is activated by a variety of stimuli, including cellular stress, cytokines, free radicals, UV radiation, oxidized LDL, and bacterial/viral infection.Activated NF-kB translocates to the nucleus, where it binds to specific sequences of DNA called response elements. This DNA/NF-kB complex then recruits RNA polymerase and other coactivators, which transcribe downstream DNA into mRNA for protein synthesis.Incorrect regulation of NF-κB has been linked to cancer, inflammatory and autoimmune diseases, septic shock, viral infection, and improper immune development.（附上图解）
"试用期"和"转正" 用英语怎么说?
1、试用期：Probation period。2、转正：Become a regular worker。3、试用期一个月1000块,转正后1200块一个月。The probationary period is 1000 yuan per month, and 1200 yuan a month after the correction.4、试用期是1到2个月。The probation period is 1 to 2 months.扩展资料：试用期例句：1、试用期结束后，你将成为长期雇员。At the end of the probationary period you will become a permanent employee. 2、那家公司给所有新员工三个月的试用期。That company puts all new employees on a three-month probation.参考资料来源：百度翻译—试用期
请老师为这篇first aid短文纠错，谢谢
基础性的语法错倒没有。主要毛病是几个句子的主、谓、宾的逻辑结构不清晰，有的关系混乱。先改了，供你参考:In our life, we always face some accidental harms. Usually these harms may not influence our normal life. But sometime, it is very dangerous having suffered from a serious harm, even causing loss of one's life. To be sure, it is necessary that we should learn some knowledge of first aid in order to prevent us from serious harm. For example，if one's carotid is punctured by sharp objects，we should let the patient lay without moving，and use towel to wrap the wound to avoid further bleeding. Then，we should resort to the hospital. Because，in normal situation，a carotid can maintain blood for 30minutes. For other example，if one suffers from an accident，we should firstly bound his injured position，and keep the patient without moving until doctors are coming. So, mastering a right method of first aid is greatly benefitial to us.
