Выписать из текста предложения с глаголами в форме причастие или герундий и сослагательное наклонение. the internal combustion engine is a machine that develops power from the combustion of fuel within a cylinder. the cycle of operation is as follows: a) suction stroke- just before the piston reaches the inner dead-centre, a valve, usually of the "poppet" type, is opened. on its outward stroke, the piston draws into the cylinder an explosive mixture of air and fuel vapour. shortly before the piston reaches the outer dead-centre, the inlet valve is closed and the compression stroke begins. 1. compression stroke- during this stroke, the whole of the gas in the cylinder is compressed into the free space at the head of the cylinder. 2. explosion, or working stroke- when the compression stroke is almost complete, the explosive mixture is ignited by an electric spark or by other suitable means. the gases reach their maximum pressure almost immediately, and work is done until the piston has again reached a position just before the outer dead- centre, when a second exhaust valve is opened. if the ignition takes place too late, the piston begins its outward journey before the maximum pressure is developed and power is lost. if, on the other hand, the explosive mixture is ignited too early, the maximum pressure is reached before the piston has completed its inward journey, and engine is slowed down or even stopped. d) exhaust stroke- the burnt gases are driven out in front of the and its return until the inlet valve again opens, when the cycle is repeated.

Hi John,

It was nice to get your letter. 

I can understand your problems quite well. Although I have some arguments with parents too, but I try to talk to them about the difficult points and explain them my position. YOu know, family talk, it helps a lot. To tell you the tryth I don't have much free time, as I have some extra classes. Though when I have some leisure time we usually go to cinema with freiends or just sit somewhere and chat.  We also like go hiking, but this is mostly for the summer, when the school is over. 

By the way how are you doing with your sister? Last time you wrote you had a big arguments over some school issues. Have you solve it or are you still at war? What about her further studues, did she decide what unversity to join?

Looking forward to hearing from you soon.

Best wishes

In January, 1856, having been persuaded to take part in an open competition for the vacant post of organist at the Cathedral in Linz, he easily carried off the honors, astonishing all by his incredible powers of improvisation on given themes.

During the first few of the twelve years he served as organist in Linz, Bruckner made practically no efforts at original composition, burying himself heart and soul in the contrapuntal problems heaped upon him by the pedantic Sechter. During the periods of Advent and Lent, the Cathedral organ being silent, Bishop Rudigier, who greatly admired Bruckner's genius, permitted him to go to Vienna to pursue (in person) the studies which throughout the year had to be left to the uncertain benefits of a correspondence course.

One may get some inkling of the stupendous physical and mental labor involved in "studying," as Bruckner interpreted the term, if one believes the evidence advanced by eye-witnesses, who assert that the piles of written musical exercises in the "student's" room reached from the floor to the keyboard of his piano. "For those who think this incredible there is the written word of the unimpeachable Sechter himself to the following effect. Upon receiving from Bruckner in a single installment seventeen bookfuls of written exercises, he warned him against "too great an intellectual strain," and lest his admonition be taken in ill part by the student, the teacher added the comforting, indubitable assurance: "I believe I never had a more serious pupil than you."
