【正文】 shing effect on gastrointestinal and anemia. Besides preventing scurvy ,it has better effect on prevention and treatment of atherosclerosis, coronary heart disease . (2) The typical digital puter has five different units or sections ,an input unit which controls the action or orders to go into the puter, a control unit which controls the actions of the puter in accordance with the input orders, a putation, or arithmetic ,unit where the arithmetic is carried out ,a reports the results.(this long sentence is constituted a parallel by five ―units‖ with attributive clause.) Frequent Use of Compound Sentences On the definition of pound sentences, there are two different views, one is the traditional point of view, which thinks pound sentences are made of the main clause and subordinate clause .The main clause is relative to the subordinate clauses. The other is the point of Quirk, who believe that subordinate clauses are an integral part of the main clause and the main clause includes the subordinate clause, the entire sentence is a pound one .In the linguistic studies, the latter is often approved In English for science and technology stylistics, in order to express some plex concept ,the pound sentences tend to be used in the most cases. These pound sentences have a special feature :there are a large number of phrases and clauses used in pound sentences ,at the same time ,there are the parallel structure or the inverted word order ,concurrently bined with nonfinite forms of verbs so that the sentence structure would be especially plex. Looked from the overall structure, the plex sentence patterns in English for science and technology are classified into four patterns: the parallel structure, the vertical structure, antecedent ―it‖ structure, periodic sentence structure First of all, the author introduces the parallel structure in English for science and technology. This kind of structure has a prominent characteristic which is to use a ma or the connectives such as and/or between the same or similar ingredients, which makes the whole article structure more pact, concise and make thinking more clear. In English for science and technology, parallel parts of the sentence often include a variety of language forms, such as: clauses, subjects, predicates and so on. The followings are the examples: Using hightech puter applications, an Environmental Monitoring(環(huán)境監(jiān)控 )/Emergency Response System（緊急處理系統(tǒng)） with a Realtime Data Acquisition（實(shí)時(shí)數(shù)據(jù)擷?。?/Analysis capability（分析能力） have bee a reality.

This article is to conceptualize a realtime environmental monitoring system as well as draft a blueprint in currently available software/hardware technologies and study the feasibility of such a system.

Davies86) In this article ,the sentences marked in bold are the parallel structure. Through the example above, as can be seen obviously ,in English for science and technology, usually reduce many parallel ponents into one sentence, forming a prominent stylistic features .In this way, sentences would be full of rhythm and have clear levels. In the second, the author introduces the vertical structure. This structure has a prominent feature which have many layers of nested ponents. Say in detail, assuming that part A is used to modify part B ,part B is used to modify part C, and part C is used to modify part D, in general, part A, B, C are used to modify part D. For example: The efforts that have been made to explain optical phenomena by means of the hypothesis of a medium having the same physical character as an elastic solid body led ,in the first instance, to the understanding of a concrete example of a medium which can transmit transverse vibration but later to the definite conclusion that there is no luminiferous medium having the physical character assumed in the hypothesis.

Then, this structure also have higher requirements to the reader39。在設(shè)計(jì)過程中，直流偏置電路作為形象化的一種輔助手段可以充分加以使用。（ 《電氣信息類科技英語(yǔ)教程》何宏， 5668） (2) As oil is found deep in the ground its presence can not be determined by a study of the surface. Consequently ,a geological survey of the underground rock structure must be carried out. If it is thought that the rocks in a certain area contain oil, a ―drilling rig‖ is assemble .The most obvious part of a drilling rig is called ―a derrick‖ .It is used to lift sections of pipe, which are lowered into the hole made by the drill .As the hole is being drilling, a steel pipe is pushed down to prevent the sides from falling in .If oil is struck a cover is firmly fixed to the top of the pipe and the oil is allowed to escape through a series of valves. (3) In this way the distinction between heavy current electrical engineering and light current electrical engineering can be said to have disappeared, but we still have the conceptual difference in that in power engineering the primary concern is to transport energy between distant points in spac
