20. Прочтите диалог. Тренируйте диалог в парах, затем постарайтесь его воспроизвести.

Student: I am a petroleum engineer and I am interested in the construction of a subsurface centrifugal pump.

Teacher: All right. You may put questions to me and I’ll try to answer them.

Student: Well, what can you say about the dimensions of such a pump?

Teacher: As far as I know, the cross-sectional dimensions of a motor are restricted by the diameter of the casing string but the length of it is quite considerable.

Student: As far as I can judge the speed of this motor must also be considerable.

Teacher: Yes, as it was mentioned in special literature the speed of subsurface pump motors is about 3000 rpm.

Student: Well, if the length of a subsurface centrifugal pump is considerable (about 7 meters) then it is not convenient for transportation?

Teacher: Right you are, for transportation the motor and pump which are quite long are placed on special racks keeping them fixed and protecting them from bending under gravity.

Student: Thank you very much for the information you have given to me.

21. Английский юмор:

1

The professor, who was famous for being absent-minded, returned home and rang at the door.

The ring was answered by a new maid. The girl looked at him inquiringly.

“Um-ah- is Professor Thompson at home?” he asked, naming himself.

“No, sir,” the maid replied, “but he is expected any moment now.”

The professor turned away, the girl closed the door. Then the poor man sat down on the steps to wait for himself.

At the Top

- A telegram from George, dear.

- Well, did he pass the examination this time?

Father: Aren’t you ashamed to be at the bottom in a class of twenty-eight boys?

Father: What do you mean, not so bad?

Willie: Suppose there were fifty boys.
