Lesson1 part A
1、protected (structure) horticulture is defined as a cultivation method taking use of heat
keeping ,chilling prevention or cooling and rainproof facilities to prevent the crops production from being influenced or seriously done by natural seasons and to artificially create a microclimate
environment suitable for growing horticultural crops in cold or hot weather hat actually unfavorable to the crop development .it is also termed as out-of-season culture ,season-off culture or forcing
culture .because of the season in which horticultural crops are planted is hand for their growing in
open field.
2、Windbreak、cold –frame 、hot-frame、 plastic-clad tunnel and greenhouse could provide a variety
of vegetable seeding for open field or protected culture or protect seeding of cold tolerant vegetable living through the winter ,for early planting and acquirement of early mature products.
3、In respect of structure type, the largest horticultural structure area in our country consists of plastic
tunnels and lean to houses, especially the energy-sawing solar greenhouse, which has become the
dominant greenhouse type in the country. Presently the development of large greenhouse or multi-
span house has been initiated.
Lesson2 part A
4、In horticultural crop cultivation under structure the key point of environment management for
growers is to create optimal complex of environmental conditions for crop growth and development, as possibly as they can, according to properties and environmental demand of crop.
Lesson3 part A
Lesson4 part A
1、most soil amendments are consisted of the increasing of organic matters ,addition of specific
nutritional elements and ph adjustment
2、the soil is an important constitute of the land loamy soil must consist of soul particles with proper
ratio ,with equilibrium of nutrients ,in which contains some organic matter ,and with considerable
moisture
Lesson5 part A
Lesson6 part A
1、sink demand of horticultural crops extremely affects photosynthetic ,for example ,leaf photosynthesis
noticeably decrease when potato tubers are removed during their growth short-term response may be stomato close effect ,but this cannot explain common continuous effects ,sometime when the source-sink ratio increases significantly ,some old leaves can renew their photosynthesis functions ,on the other hand ,rapidly growing sinks sometimes compete with leaves for mobilizable nitrogen and this results in abscission of leaves and lower photosynthesis capacity.
2、It is not clear yet that how the sink demand affect photosynthesis of leaves .the simplest explanation
is that photosynthesis accumulated in leaves restrain photosynthesis . however trials for examining
this hypothesis usually obtained the opposite results .furthermore ,in practice ,photosynthates seemly not accumulate beside chloroplasts in mesophyll cells .thus ,more research work should be done on source-sink relationship to improve yields of horticultural crops
Lesson7 part A
1、the development of horticultural crops product organs consist of maturity 、full ripeness and
senescence stages .maturity includes physiological ripeness and horticultural ripeness the former
means that in the last growth stage ,mature organs become full ripening and the later means the best growth stage of horticultural crops for harvest ,such as leaf vegetables ,when they are reaped ,they are not physiological ripe ,and flower crops are harvested when thy flower.
Full ripeness is the develop stage after fruit mature some fruits can get full ripeness in trees ,while some must ripen after separated from trees .after full ripen the flesh mealiness aroma strength proper acidity and sugar ,senescence is a stopping terminating process of living activity. In this stage,
product organs quality of horticultural crops become bad and completely leaves their economical
value in the end
Lesson8 part A
1、hormone produced by seed influence fruit setting ,fruit growth and the balance of hormones in plant
2、Stone fruits can no t set their fruits when their embryos develop abnormally. pome fruits can set
without seeds ,but flesh cells grow slowly
3、Gibberellins was produced after pollination with seed development gibberellins promotes synthesis
of auxin , therefore ,promotes fruit setting .the fruit set and fruit growth is similar between the ovule not pollinated treated by gibberellins and those which has seed
4、Gibberellins produced by apple seeds apparently restrain flower differentiation and result in alternate
fruiting .alternate fruiting is not normal in pear and many stone fruits .it is because the early
occurrence of gibberellins synthesis peak which is not concurrent with flower differentiation
initiation.
Lesson13 part A
1、pruning of fruit trees is a practice involves the heading back cuts and the thinning cuts of branches
for good framework ,for regulating contradiction between growth and fruiting ,for maintaining the equilibrium between vegetative growth and propagative growth and for good sunlight exposure, to fruit early to achieve high yield and to get commodity with high quality
2、the pruning methods are best determined by the characteristics of fruit species and cultivars ,the
climate the soil condition and the crop developing stages and growth status .in order to get the best result ,it is useful to combine pruning with other cultural practices like fertilization ,irrigation, etc 3、Reinvigoration of trees is better performed annually, which can keep fruit from stimulating excessive
sprouts .remove dead branches, sprouts and some crossing shoots. Secondly, large branches should be thinned out gradually to open tree chamber and to improve distribution of sunlight in order to
simulate fruiting.
Lesson15 part A
1、temperature is an critical element in biological ,chemical and physiological processes of all plant
species
2、Temperature regulates the rate of chemical reactions ,leading to the adjustment of plant growth rate.
3、As a important contributing factor to climate .temperature play an important role in adaptability and
growth ,date of plant thus the horticultural crop types which can be cultured in a specific area rely on temperature
4、Most plants can live and grow in the range of 0 to 50℃ .however low-temperature sensitivity limit
the successful cultivated regions of plants
Lesson16 part A
1、sprinkler irrigation is often used in maintaining and flower beds which has the specialty the uniform
water amount in its coverage .however, water waste occur when sprinkler is not limited in the area need irrigation .in addition ,evaporation result in some water loss too

01 THE ELEMENTS AND THE PERIODIC TABLE 01 元素和元素周期表 The number of protons in the nucleus of an atom is referred to as the atomic number, or proton number, Z. The number of electrons in an electrically neutral atom is also equal to the atomic number, Z. The total mass of an atom is determined very nearly by the total number of protons and neutrons in its nucleus. This total is called the mass number, A. The number of neutrons in an atom, the neutron number, is given by the quantity A-Z. 质子的数量在一个原子的核被称为原子序数,或质子数、周淑金、电子的数量在一个电中性原子也等于原子序数松山机场的总质量的原子做出很近的总数的质子和中子在它的核心。这个总数被称为大量胡逸舟、中子的数量在一个原子,中子数,给出了a - z的数量。 The term element refers to, a pure substance with atoms all of a single kind. T o the chemist the "kind" of atom is specified by its atomic number, since this is the property that determines its chemical behavior. At present all the atoms from Z = 1 to Z = 107 are known; there are 107 chemical elements. Each chemical element has been given a name and a distinctive symbol. For most elements the symbol is simply the abbreviated form of the English name consisting of one or two letters, for example: 这个术语是指元素,一个纯物质与原子组成一个单一的善良。在药房“客气”原子的原子数来确定它,因为它的性质是决定其化学行为。目前所有原子和Z = 1 a到Z = 107是知道的;有107种化学元素。每一种化学元素起了一个名字和独特的象征。对于大多数元素都仅仅是一个象征的英文名称缩写形式,一个或两个字母组成,例如: oxygen==O nitrogen == N neon==Ne magnesium == Mg

李明是学化学的，性格开朗幽默，颇有魅力，但英语成绩不佳，每次只能勉强及格。老师警告他，英语不好会阻碍他拿奖学金，并亮出了自己的王牌：如果李明不努力，就让他考试不过关。老师还告诉他，学习英语不能只为了文凭，否则他即使大学毕业，也还是个半文盲。李明虽然保持镇定，但他明白，他的学业生涯正在攸关之际，必须安心下来埋头学习，坚持不懈。 Li Ming was a chemistry major, a charmer noted for his easygoing and humorous temperament. However, his English was so poor that he always barely got by. The teacher admonished him that his poor English would be an impediment to scholarship. What’s more, she showed her trump card: if Li Ming did not work hard. She would flunk him. He was also told that he should not learn English merely for the sake of his diploma, otherwise, even after graduation from university, he would still be semiliterate. Although Li Ming did not lose his composure, he was well aware that he had to settle down to work and follow through because his academic life was at stake. Unit 2 我的朋友琳达接受过良好的教育，既美丽又端庄，三十好几依然没有人向她求婚。究其原因，她的事业心极强，整日扑在工作上，每天来往于住处和公司之间，根本没有时间和异性交往。一想到女儿这么大了还单身一人，她父母就焦虑不安。他们不知道该如何是好，甚至还去咨询一些社会学专家。但是事情在上个月出现了转机，公司的总部调琳达到培训部。在新的工作岗位上，琳达遇到了第一个触动她心弦的男人。从此，他们几乎每天约会，琳达意识到她会不顾一切地爱这个男人。决定嫁人的时候，她告诉了我这个好消息。虽然琳达的爱情让人想起电影中才会有的浪漫故事，我也担忧未来究竟会怎样，但我还是表达了我由衷的祝福，并爽快答应在婚礼那天做他们的伴娘和伴郎随从中的一员。 Linda, my good friend, has received good education and is both beautiful and elegant. She was not proposed to even when she was well over thirty. The reason is that she, as a career –oriented woman, is devoted to her work. Navigating between home and the company, she had hardly any time to socialize with people of the opposite sex. Her parents were gripped by anxiety at the thought of their daughter still remaining single at such an age. They did not know what to do and even consulted with some sociologists. But the situation began to change last month, when the headquarters of the company transferred Linda to the training department. On the new post, Linda met a man who tugged on her heartstrings for the first time. Ever since then, they dated virtually on a daily basis, and Linda realized that she would love the man beyond all reason. When she decided to take the matrimonial plunge, she informed me. Though Linda’s love is reminiscent of the romance that we see only in movies and I don’t know what the future will hold for her, I give her my heart-felt wishes and agree readily to be a member of the entourage of bridesmaids and groomsmen.
风景园林专业英语(第一二课翻译)
The practice and theory of Landscape Architecture 景观规划设计理论 【1】Landscape Architecture involves the five major components:They are natural process，human factors，methodology，technology，and values，whatever the scale or emphasis of operation，these five components are consistently relevant.Social and nature factors clearly permeate every facet of a profession that is concerned with people and land. Problem solving，planning，and design methods apply at all scales.Good judgment is consistently required. 风景园林设计包含五个主要方面:自然进程、社会进程、方法论、技术、价值观,无论规模尺度或运作的重点各不相同,这五个要素一贯是相关的。社会因素和自然因素的因子充斥着这个关系到人与土地的领域的方方面面。解决问题,规划、设计方法都会用到所有的尺度。正确的判断判断是一贯必须的。 【2】Consider how natural factors data are relevant to both planning and design.At the regional scale，the impact of development or change in use on a landscape must be known and evaluated before a policy to allow such action is set.An inventory of the natural factors，including geology，soils，hydrology，topography，climate，vegetation and wildlife，and the ecological relationships between them is fundamental to and understanding of the ecosystem to which change is contemplated.Equally important is an analysis of visual quality .Land use policy can thus be made on the basis of the known vulnerability of resistance of the landscape.In other circumstances the natural processes which add up to a given landscape at a give moment in its evolution may，as at Grand Canyon and other unique places，be considered a resource to be preserved，protected，and managed as a public trust.On a smaller scale，soil and geological conditions may be critical in the determination of the cost and the form of building foundations: where it is most suitable to build and where it is not.Sun，wind，and rain are important factors of design where the development of comfort zones for human activity or the growth of plants is a primary objective.Thus，in many ways natural factors influence land use，site planning，and detailer design. 自然因素的考虑与规划和设计都有关系。在区域尺度上，关于利用方面的开发变化的影响，在政策制定之前，必须了解和评估景观的脆弱性和敏感性。详细的自然因素,包括地质的、土壤的、水文的、地形地貌的、气候的、植被的和野生动物的、以及它们之间的生态关系是理解它将要改变的生态系统的基础。同样重要的是视觉质量的分析。土地利用政策的基础是由于了解到景观的脆弱性和抗损性的基础上建立的。在某些发展进化的过程中，一些在特定的时刻作用到特定的景观的自然进程会产生一些公共资源,比如科罗拉多大峡谷，让我们后人去保护它和管理它。在小尺度上，土壤和地质条件是决定建筑的成本和建筑基础形态的关键要素——哪里适宜建立以及哪里不适宜。设计是为人类发展活动找到适宜的空间或者以植物的生长为主要目标，因此，阳光,风和雨是设计最重要的要素。因此,场地和区域的自然要素在景观规划和设计的许多过程当中相互作用。 【3】The social factors apply equally at various scales.In site planning and landscape design，cultural variation in the use and appreciation of open space and parks and the physical and social needs of the young and old are some of the many variables to be considered in a design process that aims to be responsive to social values and human needs.In decisions relates to appropriation of landscape for recreation and aesthetic value people’s perception of t he environment and the

Unit 1 Chemical Industry 化学工业 1.Origins of the Chemical Industry Although the use of chemicals dates back to the ancient civilizations, the evolution of what we know as the modern chemical industry started much more recently. It may be considered to have begun during the Industrial Revolution, about 1800, and developed to provide chemicals roe use by other industries. Examples are alkali for soapmaking, bleaching powder for cotton, and silica and sodium carbonate for glassmaking. It will be noted that these are all inorganic chemicals. The organic chemicals industry started in the 1860s with the exploitation of William Henry Perkin‘s discovery if the first synthetic dyestuff—mauve. At the start of the twentieth century the emphasis on research on the applied aspects of chemistry in Germany had paid off handsomely, and by 1914 had resulted in the German chemical industry having 75% of the world market in chemicals. This was based on the discovery of new dyestuffs plus the development of both the contact process for sulphuric acid and the Haber process for ammonia. The later required a major technological breakthrough that of being able to carry out chemical reactions under conditions of very high pressure for the first time. The experience gained with this was to stand Germany in good stead, particularly with the rapidly increased demand for nitrogen-based compounds (ammonium salts for fertilizers and nitric acid for explosives manufacture) with the outbreak of world warⅠin 1914. This initiated profound changes which continued during the inter-war years (1918-1939). 1．化学工业的起源 尽管化学品的使用可以追溯到古代文明时代，我们所谓的现代化学工业的发展却是非常近代（才开始的）。可以认为它起源于工业革命其间，大约在1800年，并发展成为为其它工业部门提供化学原料的产业。比如制肥皂所用的碱，棉布生产所用的漂白粉，玻璃制造业所用的硅及Na2CO3. 我们会注意到所有这些都是无机物。有机化学工业的开始是在十九世纪六十年代以William Henry Perkin 发现第一种合成染料—苯胺紫并加以开发利用为标志的。20世纪初，德国花费大量资金用于实用化学方面的重点研究，到1914年，德国的化学工业在世界化学产品市场上占有75%的份额。这要归因于新染料的发现以及硫酸的接触法生产和氨的哈伯生产工艺的发展。而后者需要较大的技术突破使得化学反应第一次可以在非常高的压力条件下进行。这方面所取得的成绩对德国很有帮助。特别是由于1914年第一次世界大仗的爆发，对以氮为基础的化合物的需求飞速增长。这种深刻的改变一直持续到战后（1918-1939）。 date bake to/from: 回溯到 dated: 过时的，陈旧的 stand sb. in good stead: 对。。。很有帮助

1 Unit5元素周期表 As our picture of the atom becomes more detailed 随着我们对原子的描述越来越详尽，我们发现我们陷入了进退两难之境。有超过100多中元素要处理，我们怎么能记的住所有的信息？有一种方法就是使用元素周期表。这个周期表包含元素的所有信息。它记录了元素中所含的质子数和电子数，它能让我们算出大多数元素的同位素的中子数。它甚至有各个元素原子的电子怎么排列。最神奇的是，周期表是在人们不知道原子中存在质子、中子和电子的情况下发明的。Not long after Dalton presented his model for atom( )在道尔顿提出他的原子模型（原子是是一个不可分割的粒子，其质量决定了它的身份）不久，化学家门开始根据原子的质量将原子列表。在制定像这些元素表时候，他们观察到在元素中的格局分布。例如，人们可以清楚的看到在具体间隔的元素有着相似的性质。在当时知道的大约60种元素中，第二个和第九个表现出相似的性质，第三个和第十个，第四个和第十一个等都具有相似的性质。 In 1869,Dmitri Ivanovich Mendeleev,a Russian chemist, 在1869年，Dmitri Ivanovich Mendeleev ,一个俄罗斯的化学家，发表了他的元素周期表。Mendeleev通过考虑原子重量和元素的某些特性的周期性准备了他的周期表。这些元素的排列顺序先是按原子质量的增加,,一些情况中, Mendeleev把稍微重写的元素放在轻的那个前面.他这样做只是为了同一列中的元素能具有相似的性质.例如,他把碲(原子质量为128)防在碘(原子质量为127)前面因为碲性质上和硫磺和硒相似, 而碘和氯和溴相似. Mendeleev left a number of gaps in his table.Instead of Mendeleev在他的周期表中留下了一些空白。他非但没有将那些空白看成是缺憾，反而大胆的预测还存在着仍未被发现的元素。更进一步，他甚至预测出那些一些缺失元素的性质出来。在接下来的几年里，随着新元素的发现，里面的许多空格都被填满。这些性质也和Mendeleev所预测的极为接近。这巨大创新的预计值导致了Mendeleev的周期表为人们所接受。 It is known that properties of an element depend mainly on the number of electrons in the outermost energy level of the atoms of the element. 我们现在所知道的元素的性质主要取决于元素原子最外层能量能级的电子数。钠原子最外层能量能级（第三层）有一个电子，锂原子最外层能量能级（第二层）有一个电子。钠和锂的化学性质相似。氦原子和氖原子外层能级上是满的，这两种都是惰性气体，也就是他们不容易进行化学反应。很明显，有着相同电子结构（电子分布）的元素的不仅有着相似的化学性质，而且某些结构也表现比其他元素稳定（不那么活泼） In Mendeleev’s table,the elements were arranged by atomic weights for 在Mendeleev的表中，元素大部分是按照原子数来排列的，这个排列揭示了化学性质的周期性。因为电子数决定元素的化学性质，电子数也应该（现在也确实）决定周期表的顺序。在现代的周期表中，元素是根据原子质量来排列的。记住，这个数字表示了在元素的中性原子中的质子数和电子数。现在的周期表是按照原子数的递增排列，Mendeleev的周期表是按照原子质量的递增排列，彼此平行是由于原子量的增加。只有在一些情况下（Mendeleev注释的那样）重量和顺序不符合。因为原子质量是质子和中子质量的加和，故原子量并不完全随原子序数的增加而增加。原子序数低的原子的中子数有可能比原子序数高的原
