学习单

In a monolingual country, the language one learns is a foreign language.

在一个单语国家的语言是一个学习一门外语。

May is also in Mysore practicing now and she will be back to teach at beijingYOGA by the end of this month.

我们的中国教练单美华May现在也在印度向 Guruji Pattabhi Jois学习，她将于月底回到工作岗位。

Methods: A brain concussion was produced in rats using a simple pendulum device model. One control (n=12) and six experimental groups were used(n=12 in each group). The cerebral concussion groups were assigned to sacrifice times ranging from 1 day to 24days after injury.A Morris Water Maze memory paradigm was used to assess learning and memory function. Pycnosis degeneration or necrosis neurons in the locus cerebral cortex, dorsal hippocampus, dentate fornix and brainstem reticular formation were observed and counted after brain concussion. Cholinergic neurons in the basal forebrain and brainstem reticular formation were identified and quantitated using choline acetyltransferase.

应用自制单摆式闭合性机械打击装置建立脑震荡大鼠模型；成年SD大鼠随机分为1个对照组(n=12)和6个脑震荡组(即伤后1、2、4、8、16、24d，n=12)；应用Morris水迷宫(Morris Water Maze，MWM)实验评价大鼠的学习记忆功能；用光镜对大鼠的上述脑区的固缩变性坏死细胞进行观察和计数；用免疫组化方法检测基底前脑和脑干网状结构的胆碱乙酰转移酶(cholin acetyltransferase，ChAT)阳性细胞的表达。

Finally, scopoletin ameliorated the scopolamine induced memory impairment on water maze and elevated plus maze in rats. Scopoletin selectively inhibited the activity of acetylcholinesterase and monoamine oxidase, and increased the NE and DA concentrations in cortex.

最后，scopoletin 於 0.03、0.1 mg/kg 剂量下，对 scopolamine 诱导大鼠在水迷宫以及十字迷宫学习操作障碍之现象均具有改善作用影响，此作用应与降低大鼠脑内皮质区乙醯胆碱酯酶及单胺氧化酶活性，增加皮质区内 NE 及 DA 浓度有关。

"Hang Zhu violin concerto" improved the abilities of spacial learning and memory in mice. Its mechanism we infer is that the decrement of the activities of TchE and MAO in the cerebra resulted in the increment of neurotransmitters. But "Mozart violin concerto in D Major" have no role in the abilities of spacial learning and memory in mice.

《梁祝小提琴协奏曲》能明显提高昆明小鼠的空间记忆能力，可能与该音乐引起的脑组织的乙酰胆碱酯酶和单胺氧化酶的活性降低，减少脑组织神经递质的降解，增加其浓度，促进学习记忆能力有关；而在本研究中《莫扎特D大调小提琴协奏曲》效果不明显。

Results Singlefactor logistic regression analyses showed that there were very significant differences in 11 factors between the 2 groups（all P＜0.01）;multiplefactor conditional logistic regression analyses in the 11 factors showed that the main risk factors of psychoactive drug abuse in middle school students were parents' drug abuse,poor performance record,absent from class,violence,selfconscious loneliness and unharmony family relation,the main protective factor was more exchanges between parents and children.

结果 两组自拟问卷单因素Logistic回归分析发现，11个因素有极显著性差异（P均＜0.01）；将11个有显著意义的因素进行多因素条件Logistic回归分析，结果发现影响中学生精神活性药物滥用行为的主要危险因素为父母有药物滥用、学习成绩差、缺课、暴力行为、自觉孤独、家庭关系不和睦，而多与父母交流则为主要保护因素。

Complicated tactic and technique combined training, move training, training for difficult techniques that are usually hard to grasped in one-on-one training, athlete's physical, mental and volitive capacity exercises, are implemented in the entire multi-ball teaching and training via the use of such 3 training means as "multi-point plus multi-ball","interactive multi-point plus multi-ball" and "single training with multi-ball", intensified training is carried out in an action specific way by means of ball supply, and the said problems are settled one by one.

教学设计理念是按照乒乓球技能形成的规律：泛化、分化、巩固、自动化4个阶段来设计多球训练方案，对乒乓球技能形成的各个阶段的学习、动作技能形成；对较复杂的技战术组合练习、步法及平时在对练中很难上手的难度技术；对运动员身体、心理、意志品质的锻炼等通过&多点多球&、&交互式多点多球&、&多球单练&3种训练手段，贯穿于整个多球教学与训练中，以供球的形式有针对性地进行强化训练并一一加以解决。

In this model, non-singleton fuzzier was introduced into regular neural network, so that noise could be removed from train data adaptively.

该算法将非单点模糊化技术引入正则神经网络，在自学习的过程中，能够自动滤除训练数据中的噪声，获取准确的信息。

This year 150 Harvard undergraduates are studying, researching or interning in China alone.

今年单在中国，就有一百五十名哈佛大学本科生在这里学习，研究，或实习。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
