Participle I–II Text A: Plant, its Parts and their Functions Text B: Plant Причастия настоящего и прошедшего времени (Present Participle, Past Participle) В английском языке причастие (the Participle) — это одна из неличных форм глагола, наряду с инфинитивом (the Infinitive) и герундием (the Gerund). В английском языке причастие одновременно выполняет функции таких частей речи, как прилагательного, глагола и наречия. В нашем родном языке функции Participle I выполняет деепричастие и отвечает на вопрос: «Что делая?». Английскому языку не известно деепричастие, поэтому английское причастие совмещает в себе русское причастие и деепричастие. Например: Причастие: Мальчик, листающий журнал…– The boy flipping magazine… Деепричастие: Просматривая книгу, мальчик нашел много интересных фактов. – Looking through the book, the boy found a lot of interesting facts. В английском языке известно 2 вида причастия: причастие настоящего времени (Participle I или Present Participle) и причастие прошедшего времени (Participle II или Past Participle). Причастие настоящего времени образуется путем добавления к основе глагола (инфинитиву, но без частицы to) окончания -ing. Например: to work – работать, working – работая. Чтобы выразить отрицание, перед причастием ставится частица not. Например: not paying attention – не обращая внимание. Причастие настоящего времени в английском языке имеет 4 формы: Simple Active (простое длящееся, действительный залог): surprising – удивляющий, удивляя; Simple Passive (простое длящееся, страдательный залог): being surprised – удивляемый, будучи удивленным; Perfect Active (завершенное, действительный залог): having surprised – удививший, удивив; Perfect Passive (завершенное, страдательный залог): having been surprised – был удивлен, будучи удивленным. Для образования причастия прошедшего времени необходимо: 1) у правильных глаголов (Regular Verbs) к основной инфинитивной форме без частицы to добавить окончание -ed. improved – улучшенный; 2) у неправильных глаголов (Irregular Verbs) причастие прошедшего времени соответствует 3 форме неправильного глагола. taken – взятый. Причастие II в английском языке выполняет в предложении функции определения к существительному (cooked dinner – приготовленный ужин либо обстоятельства: when asked he did not answer – когда его спрашивали, он не отвечал.

Read and translate the text. Plant, its Parts and their Functions Plants are highly important sources of food for man. They supply us with food clothing and many other things as well. Plants are grown and used for many purposes and as scientists continue their work new uses of plants will be found. The principle parts of the plant are: 1) the root system, 2) the stems and leaves, 3) the reproductive part made up of flowers, fruits and seeds. The roots grow downward into the soil and have two main functions – to absorb plant nutrients and water from the soil and to anchor the plant. As to stem and leaves, they are usually above the ground. The food used in growth by green plants is manufactured in the leaves from the raw materials taken from the soil and air. This process is known as photosynthesis. To support the leaves and to connect them with the roots are the main functions of the stem. Each flowering plant has leaves. A typical leaf consists of a green, broad, thin portion, which contains a system of vascular tubes called veins. The latter serve as channels for the distribution of water and dissolved substances and for removing a part of the food which is manufactured in the leaves for the use by the plant. The shape and the position of the leaves vary to a considerable extent with the species. Leaves may be born on a leaf stem, or attached directly to the plant. They may be compound as with clover and potatoes, or simple as in the case of the poplar tree. A flower is the part of the plant where seeds are produced. Thus, to produce seeds the plant must have flowers. A seed consists of an embryo and one or more seed coats. All parts of the plant must be developed well and proportionally enough to function properly. If conditions for plant growth are bad, the plant will be too weak to develop its parts well. 3.

They include such organisms as trees, herbs, bushes, grasses, vines, ferns, mosses and algae. The scientific study of plants, known as botany, has identified about 350 000 species of plants. Green plants obtain most of their energy from sunlight via a process called photosynthesis. About 350 000 species of plants, defined as seed plants, bryophytes, ferns exist currently. Some 287 655 species had been identified, of which 258 650 are flowering plant, 16 000 bryophytes, 11 000 ferns and 8 000 green algae. Most of the solid material in plant is taken from the atmosphere. Through a process known as photosynthesis, most plants use the energy of sunlight to convert carbon dioxide from the atmosphere, plus water into simple sugars. Parasitic plants, on the other hand, use the resources of its host to grow. Chlorophyll, a green-colored, magnesium-containing pigment is essential to this process; it is generally present in plant leaves, and often in other plant parts as well. For the majority of plants to grow successfully they also require oxygen in the atmosphere and around their roots for respiration. The genotype of a plant affects its growth. Growth is also determined by environmental factors, such as temperature, available light, and available nutrients in the soil. Human cultivation of plants of agriculture is the bases of human civilization. Much of human nutrition depends on land plants either directly or indirectly.

Unit 4 Grammar Revision: Passive Voice Text A: Flower Text B: Functions of Flowers Страдательный залог (Passive Voice) Форма залога показывает, является ли подлежащее в предложении (лицо или предмет) производителем или объектом действия, выраженного сказуемым. Пассивный залог (Passive Voice) показывает, что лицо или предмет, выраженное подлежащим, испытывает действие на себе: The big cake was baked by Sam. Большой пирог был испечен Сэмом. Пассивный залог употребляется, когда исполнитель действия очевиден или несуществен, или когда действие или его результат более интересны, чем исполнитель. Образование пассивного залога Для того, чтобы получить форму глагола в пассивном залоге, необходим вспомогательный глагол to be в соответствующем времени, лице и числе и причастие прошедшего времени (Participle II) значимого глагола: This building will be demolished next month. – Этозданиебудетснесеновследующеммесяце. My dog has been stolen. – Моюсобакуукрали. В отрицательных предложениях частица not ставится после вспомогательного глагола, а если их несколько, то после первого из них: He has not been seen anywhere. – Егонигденевидели. В вопросительных предложениях вспомогательный глагол (или первый из них) выносится на место перед подлежащим: Was your wallet stolen? – Вашбумажникбылукраден? Таблица 3 – Временные формы глагола в страдательном залоге (Passive Form) To be + Participle II
Пассивный залог не может быть использован во временах группы Perfect Continuous и времени Future Continuous. Употребление и перевод глаголов в пассивном залоге Значение и употребление времен глагола в пассивном залоге такое же, как и времен глагола в активном залоге. В английском языке в пассивном залоге употребляются переходные глаголы, а также некоторые непереходные глаголы. Примеры предложений с переходными глаголами в пассивном залоге: By the middle of the nineteenth century about sixty different elements had been discovered. – Ксередине XIX столетиябылобнаруженооколо 60 различныхэлементов. The delegates will be met at the station. –Делегатоввстретятнавокзале. While a current is flowing through a wire, the latter is being heated. –Когдатокпроходитпопроволоке, последняянагревается. Как видно из приведенных примеров, глагол в пассивном залоге в английском языке можно переводить на русский язык несколькими способами: а) глаголом, оканчивающимся на -ся, -сь; б) сочетанием глагола быть с краткой формой причастия пассивного залога (в русском языке в этом сочетании глагол быть в настоящем времени не употребляется); в) глаголом в активном залоге в 3-м лице множественного числа в составе неопределенно-личного предложения. Дополнение в предложении с глаголом-сказуемым в пассивном залоге употребляется с предлогом by или with. Это дополнение соответствует русскому дополнению в творительном падеже без предлога.

Consequently, it is highly important that the flower develop and function properly so as to assure a good yield of seeds. If you want to understand how plants produce seeds, it is necessary that you be familiar with the parts of the flower and the role of each in the reproduction process. |
