brought wanted drank anything something funny
wasn't quickly fell running
Last weekend I went to my friend Tom's house and we slept in a tent in his garden. There were five of us
and we all (0) brought food to eat. We had pizza, cake and ice cream. After eating we played (1)
funny games and laughed a lot. It was very late and we were tired.
My friends (2)
asleep but I couldn't sleep because Tom snored! Then I heard strange
noises in the garden. I was scared because I thought it was a ghost! I turned on my torch but I couldn't
see (3)
But then I heard a strange noise again. I opened the tent door and ran (4)
into Tom's house. I slept on the sofa in the living room.
The next morning my friends laughed at me. The strange noise wasn't a ghost - it was Tom's dog.
He (5) wanted to come into the tent to eat some pizza!​

Отметим на бумаге черточкой положение указателя при нерастянутой пружине. Эта отметка будет нулевым делением.2. Подвесим к крючку динамометра груз массой 102г. На груз т 3D 102г действует Fтяж %3D 1Н. С такой же силой груз растягивает пружину динамометра. Эта сила уравновешивается силой упругости, возникающей в пружине при ее растяжении (деформации).Затем самостоятельно подвешивайте к динамометру второй, третий грузы той же массы. Отмечая черточкой положение указателя.Госле того как вы отметили положения указателя динамометра, нарисуйте проградуированную шкалу в тетрадь. С линейки получите шкалу с ценой деления 0,1 Н (стр.15 тетради).Выполнить задания 6,7 в тетради. Измерить проградуированным динамометром вес каких-либо тел и определить их массу. Закрепление изученного материала Как называется прибор для измерения силы? Как определяется цена деления прибора? Как сделать динамометр, которым можно измерить малье силы? Чему научились в ходе выполнения лабораторной работы?

1 The internal combustion engine is called so because fuel is burned

directly inside the engine itself

2 To describe the complete cycle, let's that the piston is

the top of the stroke (top dead center) and the and the exhaust

valves are closed, When the piston

moves down the inlet valve opens to

intake a charge of fuel into the cylinder. This is called the inlet (intake)

stroke. 

3 On reaching the lowest position (bottom dead center) the pis-

der,

begins move upward the closed upper part the cylinder,

the valve is closed and the mixture is compressed by the rising

piston. This is called the compression stroke.

4 Asthe piston again

the top dead center the spark plugs ignite the mixture, hoth valves he

ing closed during its combustion. As a result of burning mixtures the

gases expand and great pressure makes the piston move back down the

cylinder. This stroke is called the

reaches

powerstroke

5  When the piston reach

the bottom of its stroke, the exhaust valve is opened, pressure is re-

lensed, and the piston again rises. It lets the burnt gas flow through the

exhaust valve into the atmosphere. This is called thexhaust stroke

which completes the cycle

6  So the piston moves in the cylinder down

(intakestroke), up (compression stroke), down (powerstroke), up (ex-

hanst stroke)
