1. Read and translate the sentences in which the Gerund is used as:

1) subject (подлежащее);

- Reading such books is necessary.

- Using concrete without cement is impossible.

2) part of a predicate (часть сказуемого);

- Seeing is believing.

- The young scientist began experimenting.

3) direct object (прямое дополнение);

- He likes reading about new building materials.

- He remembers being shown this project.

4) indirect object (косвенное дополнение);

- He insisted on adopting a new plan.

- They succeeded in solving the problem.

5) attribute (определение);

- We discussed different methods of manufacturing Portland cement.

- This new mixer is used for mixing concrete.

6) adverbial modifier (обстоятельство);

- Without knowing the result we can’t draw a conclusion.

- We were able to carry out various digging operations by using a powerful crane.

2. Point out the gerunds; translate the sentences:

1. A beam of such material would fail under fairly light loads owing to the tensile stresses due to bending. 2. When a beam is bent, due to the application of a constant bending moment without being subjected to shear, it is said to be in a state of simple bending. 3. A beam of uniform section is shown resting in the unloaded state. 4. The fibers at one side of the beam will be shortened owing to the state of compression existing. 5. Such elements such as excavation procedure, concrete handling, dredging, or making sand from rock require careful consideration in the light of past experience. 6. Further improvements were made under actual operating conditions and resulted in a very satisfactory type of structure. 7. On a large dam project the topography of the site is one of the controlling factors in determining the construction procedure. 8. The matter isn’t pressing. I can wait for it being discussed at the next meeting.

III. Reading Comprehension.

  1. Read and translate the text: concrete

Concrete is the most common building material for modern construction practice. It consists of cement used as a binding agent and aggregate, for example crushed stone and sand. These components are mixed with water. The cement is hardening and thus making the particles of the aggregate adhere close to each other. The setting and hardening of concrete are due to chemical reactions between the cement and mixing water. Fixed limiting means, in most cases formwork, are used to shape the building unit according to the plan. The concrete is filled into the formwork immediately after mixing and is then compacted. The formwork can be removed as soon as the concrete has become hard enough.

Concrete is suitable for various applications in building because different properties can be imposed to it by an appropriate selection and composition of the basic materials and by using special admixtures and methods of fabrication.

Good concrete is influenced by the following factors:

1. Cement, which should be of superlative quality.

2. Aggregate, which should be carefully selected, graded and proportioned.

3. Water-cement ratio. Surplus water weakens the strength of the concrete.

4. Workmanship in mixing, placing and finishing the concrete.

5. Curing, the proper time during which the concrete is kept humid in order that the setting and hardening processes may complete themselves under favourable conditions.

Notes to the text:

1. due to

благодаря

2. in most cases

в большинстве случаев

3. according to

согласно

4. as soon as

как только

5. in order to

для того, чтобы

6. under favourable conditions

при благоприятных условиях

  1. Answer the following questions:

1. What does concrete consist of? 2. What is aggregate? 3. What happens between the cement and mixing water? 4. Why is concrete suitable for various applications? 5. How many factors influence concrete? 6. Cement should be of superlative quality, shouldn’t it? 7. What is curing?

IV. Comprehension and Word Study.

1. Translate into English:

Строительные материалы, современное строительство, вяжущие материи, измельченный камень и песок, химическая реакция, схватывание и твердение, опалубка, в соответствии с планом, различные использования, соответствующий отбор, превосходное качество, избыток воды, смешивание, укладка, обработка.

2. Put all possible questions to the following sentence:

Concrete is suitable for various applications in building because different properties can be imposed to it by an appropriate selection and composition of the basic materials and by using special admixtures and methods of fabrication.

3. Translate the following sentences, pay attention to the words with “-ing” endings.

1. Concrete may be made on a building site. 2. Concrete may be used as the material for making prefabricated units in a factory. 3. The rapid-hardening types of cement give the concrete high early strength. 4. There is an increasing tendency to use lightweight varieties of concrete. 5. After setting concrete may carry loads. 6. It is possible to increase hardening by mixing a small proportion of calcium chloride with cement.
