得时

It is predicted by the Aspect Hypothesis that the perfective and imperfective aspect marking in native language and learner's interlanguage is constrained by the lexical aspect of the verb.

第二语言时体系统的习得是二语习得研究的一个核心领域。动词的情状体是影响二语时体习得的重要因素之一。情状体假设一方面揭示了语言中的一个普遍语法现象，即体范畴中的情状体特征；而且发现了这一语法现象对语言习得的作用。

Gibson, who had come down to direct his sister's interment and settle the family affairs.

乔治亚娜害怕同伊丽莎单独相处，说是情绪低沉时得不到她的同情；胆怯时得不到她的支持；收拾行装时得不到她的帮助。

And she saw a long Roman candle going up over the trees, up, up, and, in the tense hush, they were all breathless with excitement as it went higher and higher and she had to lean back more and more to look up after it, high, high, almost out of sight, and her face was suffused with a divine, an entrancing blush from straining back and he could see her other things too, nainsook knickers, the fabric that caresses the skin, better than those other pettiwidth, the green, four and eleven, on account of being white and she let him and she saw that he saw and then it went so high it went out of sight a moment and she was trembling in every limb from being bent so far back that he had a full view high up above her knee where no-one ever not even on the swing or wading and she wasn't ashamed and he wasn't either to look in that immodest way like that because he couldn't resist the sight of the wondrous revealment half offered like those skirtdancers behaving so immodest before gentlemen looking and he kept on looking, looking.

她瞧见一只长长的罗马蜡烛高高地蹿到树木上空，高高地，高高地。大家紧张地沉默着。待它越升越高时，大家兴奋得大气儿不出。为了追踪着瞧，她只好越发往后仰。焰火越升越高。几乎望不到了。由于拼命往后仰，她脸上洋溢出一片神圣而迷人的红晕。他还能看到她旁的什么：抚摩皮肤的印度薄棉布裤衩，因为是白色的，比四先令十一便士的那条绿色佩蒂怀斯牌的看得更清楚。那袒露给他，并意识到了他的视线；焰火升得那么高，刹那间望不到了。她往后仰得太厉害，以致四肢发颤，膝盖以上高高的，整个儿映入他的眼帘。就连打秋千或膛水时，她也不曾让人这么看过。她固然不知羞耻，而他像那样放肆地盯着看，倒也不觉得害臊。他情不自禁地凝望着一半是送上来的这令人惊异的袒露，看啊，看个不停：就像着短裙的舞女们当着绅士们的面那么没羞没臊。

The reference and echo signal were separately measured when the hard target was still, in positive rotation and negative rotation.

Based on the obtained data and evidence, this research project draws the following conclusions: Chinese L2 learners of English are sensitive to Subjacency and the ECP, thus sensitive to UG; Chinese L2 learners'sensitivities to different constraints are different; Chinese L2 learners tend to reject a lower rate of the sentences with both Subjacency and the ECP violations than those with only Subjacency violation; and there is no significant difference in L2 learners'sensitivity to UG as far as the learners'starting age of learning a L2 is concerned.

通过对调查所得数据的统计和分析，研究者发现：中国人习得英语时对普遍语法是可及的，他们对疑问词移动的不同限制的可及程度不尽相同。研究者还发现，母语为汉语的英语习得者，判断只违反界限原则的句子和判断既违反界限原则又违反空语类原则的句子语法是否正确时，对只违反界限原则的句子判断的正确率更高些。关于开始习得二语的年龄与普遍语法的关系问题，研究者并没有发现两者之间存在着必然的联系。

The biomechanical tests showed that two kinds of artificial bones had not significant difference on compressive strength and Young\'s modulus(P＞0.05),while the flexural strength of nano-nacre artificial bone was less than the control group(P＜0.05).3.The results of CCK-8 showed that the difference were not significant in each group,the proliferation of osteoblast reached the peak at the 5th day;7 days after being co-cultured,the total protein content of study group was higher than control group and blank group(P＜0.05),while the difference between control group and blank group was not significantP＞0.05The difference of alkaline phosphatase activities among three groups was not significant(P＞0.05The SEM view showed that osteoblast attached and grew well in two kinds of artificial bone.4.X-ray photography showed that two kinds of powder started to degrade in 2 weeks;this phenomenon became more appear in 4 weeks,nano-nacre powder degraded faster than micron-nacre powder,while the hole shadow was easy to be found;in 8 weeks,all the femoral holes recovered and returned to normal bone mineral density in all groups.Analysis of tetracycline fluorescent double marks in the hard tissue grinding slices indicated that new bone grew fastest around the bone defect area in study group,while most slowly in blank groupP＜0.05 SEM(scanning electron microscope observation showed that nano-nacre powder degraded more quickly.The same result can be found through the demineralized sections morphometric analysis,and both of the composite artificial bones made from those two kinds of nacre powder had the good connection with the adjacent tissue in rats body without apparent inflammatory response.5.X-ray photography showed that rabbit\'s bone defects healed faster in study group since NNAB implanted than in control group since MNAB implanted.At 24 weeks after operation,bone density in radial defects had nearly accessed to the normal area,while lower in control group,and turned up nonunion in blank group;The checking of BMD showed that results in study group were higher than those in control group at 8,16 and 24 week(P＜0.05), and the difference between the BMD values in study group at 24 week and those in blank group was not significant(P＞0.05).The gross specimens showed satisfactory histocompatibility both in study group and in control group,with bone tissue growing from two sides into the center of implanted materials; Normal slices in HE stain and hard tissue grinding slices in Stevenel\'s blue/Van Geison\'s picro-fuchsin stain showed that the bone growth tendency was better in study group than that in control group,and the medullary cavity had been penetrated to the implanted materials in study group at 24 week;Analysis of tetracycline fluorescent double marks in the hard tissue grinding slices indicated that new bone in both groups grew fastest 8 weeks after surgery,while slow down at 16 week.

Every nature is contented with itself when it goes on its way well; and a rational nature goes on its way well, when in its thoughts it assents to nothing false or uncertain, and when it directs its movements to social acts only, and when it confines its desires and aversions to the things which are in its power, and when it is satisfied with everything that is assigned to it by the common nature.

每一本性当它在循自己的路行进得很好时都是满足于自身的，当一个理性的本性在其思想中不同意任何错误的或不确定的东西时；当它使自己的活动仅仅指向有益于社会的行为时；当它把它的欲望和厌恶限制在那属于自己力量范围之内的事物上时；当它满足于那普遍本性分派给它的一切事物时，我们就说一个理性的本性循自己的路行进得很好。
