在带有形容词或副词最高级的句子中,常常有一个表示比较范围的介词短语作状语,用来表达某人或某物在什么范围内最怎么样。常用的介词是IN,OF,AMONG,这三个词在用法上有所不同:一、介词IN后面常接的是表示单位、团体、组织、时间概念等单数名词或代词。HE IS THE BEST STUDENT INOUR CLASS.他是我们班成绩最好的学生。THAT WAS THE MOST EXCITINGMOMENT IN2002.那是2002年最激动人心的时刻。THERE IS A FACTORY NEAR OURSCHOOL.HE IS THE OLDEST IN IT.我们学校附近有一座工厂,他是里面年纪最… 相似文献

The purpose of the current study was to examine the nature of the relationship between learners’ distrust of scientific models that represent unseen entities and phenomena, their spatial ability, and the vividness of their mental images. The sample consisted of 302 tenth grade students in the Sultanate of Oman. Three measures were used for this study: the Epistemologies about the Credibility of Scientific Models instrument, the Water Level Task (WLT), and the Vividness of Microscopic Mental Images. It was found that students’ distrust was greater for theoretical and abstract models such as the electron clouds, photons, magnetic lines of force, DNA, electron transfer, atomic orbits, and alpha rays. The findings also show that there was a statistically significant negative correlation between students’ distrust of scientific models and their spatial ability, as indicated by their performance on the WLT. There was a positive relationship between the distrust of scientific models and the vividness of mental images and a weak negative relationship between spatial ability and the vividness of mental images. Based on the findings, it might be plausible to conclude that as the abstraction level for scientific models increases, such as for theoretical models which lack defined structure and known details, imaginative learners’ difficulty to construct colorful and detailed mental images for natural entities and phenomena increases. It would also be recommended that learners with vivid mental images should be provided with and directed to use more spatial techniques such as computerized visualization tools and mental manipulation of 3D objects. 相似文献

This paper reports on the understanding of three key conceptual categories relating to the kinetic particle theory: (1) intermolecular
spacing in solids, liquids and gases, (2) changes of state and intermolecular forces and (3) diffusion in liquids and gases,
amongst 148 high school students from Brunei, Australia, Hong Kong and Singapore using 11 multiple-choice items that required
students to provide explanations for their selection of particular responses to the items. Students’ responses to the items
revealed limited understanding of the particle theory concepts, with nine alternative conceptions held by more than 10% of
various samples of students. Also, 40.5–78.4% of all students indicated consistent understanding relating to the three conceptual
categories based on their responses to the 11 items. However, when their explanations were taken into account, very few students
displayed consistent understanding of the related concepts. 相似文献

The ethos of the Enlightenment placed religious and spiritual concerns in a private sphere, while politics became a public concern. In this vein, many American educators, including John Dewey, have vigorously insisted that public schools remain free from religion while inculcating a common civic virtue. Recently, however, educational theorists and practitioners influenced by Dewey have worried about the public's lack of spiritual intelligence and have asked how democracy and spirituality might be reconciled within schools. I approach this question through an examination of Elmer Thiessen's Teaching for Commitment: Liberal Education, Indoctrination, and Christian Nurture (1993). While not a follower of Dewey, Thiessen's work raises important questions for those who follow Dewey and who are concerned with the relationship between democracy and spirituality. 相似文献

How do children acquire their mother tongue? Are the process in acquiring L1 (first language) and L2 (second language) the same? These questions always arouse the interests of the linguists. For many years, linguists have made a lot of research on first language acquisiton. They have put forward several hypothesis 相似文献

An open-ended coaxial line reflection method especially suitable for meas-uring the dielectric properties of biological tissue in vivo is described.This method offersthe advantage of not requiring any special preparation of the samples to be measured but aclose contact with the open end of a coaxial line.It is,therefore,very convenient to acquirea large number of measurement data in broad band rapidly.The method may also be usedto measure the properties of other substances.The measuring system consists of a networkanalyzer controlled by a microcomputer and calibrated by using ANA procedure to elimi-hate the influnce of error network introduced by the adapter,some connectors,etc.In or-der to reach higher accuracy,the iterative method is used to determine the parameters ofthe equivalent circuit.Measurements of permeativities of some living tissues have been per-formed in the frequency band of 0.5-2GHz.Compared with the results known in somepapers,the validity of this method has been confirmed.The difference in dielectric proper-ties between living and dead tissues,and the tissue permeativites(ε)versus frequency andduration of measurement after death have also been measured. 相似文献
