中考考点归纳与链接——重点语法

<正>★代词it, one, that的用法区别1.它们均作代词指代前文提到的名词。但it所指的是同名同物,one和that所指是同名异物。◇例如:I like the bike, but I have no enough money to buy it.(我喜欢这辆自行车,但我没有足够的钱买它。)     

反身代词知多少

<正>反身代词又称自身代词,它是一种表示反射或强调的代词。它由第一人称、第二人称的形容词性物主代词和第三人称的人称代词宾格加词尾-self或-selves构成:一、作及物动词或介词的宾语,表示动作返回到主语本身。例如:I want to build myself a country house.我想给自己建一座乡间别墅。但在表示位置的一些介词之后常用代词宾格代替反身代词。例如:     

一“分”一“合”话区别

<正>英语中有这样一类词语,它们合写和分开写在表意及功能方面都有所差别,若不加以分析比较,同学们很容易混淆。现将这类词语列举出来,看看区别在哪里。1.every one与everyone every one意为"每个(人或物)",可指人,也可指物,其后可加of短语,用作主语时,谓语动词用单数形式。例如:Every one of us likes English.Every one of the books is interesting.everyone意为"每人;大家",其用法相当于everybody,属不定代词,在句中可作主语和宾     

定语从句典型错误简析

<正>中学英语六大从句中,定语从句的使用频率是非常高的。但学生因为受制于汉语思维,常常会在该从句的使用中出现错误的情况。通过学生的作业、考试等情况的分析总结,笔者总结出学生使用定语从句主要有以下几种典型的错误:1.先行词出现在定语从句中例如"This is the book he is looking for it."该句中的关系代词that/which代替先行词the book在定语从     

Effect of Curing Temperature on Mortar Based on Sustainable Concrete Material＇s and Poly-Carboxylate Superplasticizer

Nowadays, technologies in construction field have offered several kinds of chemical admixtures, which offer different behaviors at the fresh state of the batch and by consequence, it is resulted with different mechanical behaviors at the solid state of the mix. This study focused on the behavior of a new kind of admixture at fresh and solid states. Currently, the concrete material has become a very expensive material because the high price mostly of aggregates, representing the three quarters of the concrete components. By consequence, it costs money and on the other hand, it produces a lot of wastes. The main aspect which guides this study is to make a kind of concrete based mainly on local material and sustainable concrete material （SCM or waste material）, which is one very abundant material in quality and quantity, under the current tendency the results obtained in this study summarize up the importance of the temperature during the development of the mechanical characteristics of mortar, mainly on compressive strength at age of 28 days. This is in the case of the addition of limestone crushed additive by percentage of substitution.     

The Review and Prospect of Chinese Urban Planning from 1980s to 1990s

Ⅰ.Chinese Cities and Towns in1980sThe development and changes ofChinese cities and towns over the last dec-ade had been most extraordinary,which at-tributed both to its thousand-year-civiliza-tion-history and development process sincethe founding of the P.R.China.The devel-opment changes are in both “quantity” and“quality”.Although it is a bit difficult tosummarize all the changes,at least,it is pos-sible to sum up the following subjects fordiscussion.     

直觉的理性与理智的感性

正你可能觉得,在项目刚开始或建成之前,她的作品倚赖直觉而我们(OMA)的作品依靠理性;而一旦项目完成后,我们的作品变成了直觉性的——或者说不那么复杂——而她的作品却是图解性的。It sounds as if you are saying that in the beginning,or before it is realized,her work is intuitive and ours(OMA's)isrational.But once it is realized,our work is intuitive-or at least complex-and hers is diagrammatic.     

A Probe into the Organic Renewal of Urban Cells and the New Type “Courtyard House”

This is an attempt to explore the renovation of Beijing's old town.The endeavour has already been going on for awhole decade,evolving from plan formulation to its implementation,and at present,work on it is still in progress.The following is the first report which attempts to expound on the following issues from the perspective of academicthinking:1.Reflections upon the work of reconstruction of the old town2.Theoretical premises for exploring new directions3.Research and experiments4.Methodological thinking and expectations     

Editor's Note

正If urban mobility is regarded as a humanistic expression of urban transportation, which is at the same time an important index representing the modernization level of cities, it should undoubtedly concern the disabled as part of vulnerable groups of the society. After Niels Bank-Mikkelsen championed the normalization principle in 1959,     

Bending Stresses of Steel Web Tapered Tee Section Cantilevers

Although commonly used, no design method is available for steel web tapered tee section cantilevers. This paper investigates the bending stresses of such beams. Relationships between the maximum compressive stress and the degree of taper were investigated. An analytical model is presented to determine the location of the maximum stress when subjected to a uniformly distributed load or a point load at the free end and was validated using finite element analysis and physical tests. It was found that the maximum stress always occurs at the support when subjected to a uniformly distributed load. When subjected to a point load at the free end and the degree of taper is up to seven, it was found that Miller＇s equation could be used to determine the location of the maximum stress. However, it is shown that when the degree of taper is greater than seven, Miller＇s equation does not accurately predict the location and the analytical model should be used. It was also found that the location of the maximum stress was solely dependent on the degree of taper, while a geometric ratio, fl was required to determine the magnitude of the maximum stress. A simple method that predicts the magnitude of the maximum stress is proposed. The average error in the prediction of the magnitude of the maximum stress is found to be less than 1.0%.
