There is very simple way of measuring the height of a water-tower, which we cannot measure by climbing.
Suppose, for example, that we wish to find out the height of the water-tower, AB, in a factory. We first of all go to where the water-tower is standing and measure a distance of, say, 25 feet from it. Then we take a stick, and stand it in the ground at the spot we have just marked.
Let us suppose the stick we are using is 4 feet in height. We now walk farther away from the water –tower in the same straight line as when we measured off the distance of 25 feet. We go from the water-tower until we come to point E, where with our head on the ground, we see the top of the stick and the top of the water-tower in the same height line---that is, the top of the stick just covers the highest part of the water-tower. Every schoolboy can work out the height of the water-tower now.
Suppose that the line CE is five feet. We know that the stick is 4 feet high and the distance BE is 30 feet. Thus, 5 is to 4 as 30 is to AB.

When John Weston awoke that morning, he remembered that his mother was going into hospital. He hadn’t worked out quite what was wrong with her. He knew, though that she hadn’t been well for some time now, and it had become almost familiar to him to see her eyes narrowed in a sudden attack of pain, and her hand pressing against her heart. Their own doctor, who she had finally gone to for advice, had sent her to an expert who knew all about these things. He had told her that just as soon as there was a bed for her, she would have to come into his hospital where he could look after her himself.
During the weeks since then the pains had come even more frequently, and the narrowed eyes became an almost permanent part of her expression. Always rather sharp, she began losing her temper over little things so that John’s father kept his thoughts to himself more and more. John, as ready as possible to make allowances, tried to think what it would be like to have toothache all the time and how bad-tempered that would make you.
So his mother would go into hospital for a few days. He was going to stay with his Aunt Daisy till she came back, and his father would stay on at home by himself. John’s cousin, Mona, was to come in and make the bed and wash the pots and dust round now and again. That was the arrangement, and John didn’t care much for it. Apart from missing his mother(and he was glad she was going away because they would make her better), he wasn’t very fond of his Aunt Daisy because she was even more bad-tempered than his mother.

The house next door had been empty for so long that we had quite forgotten what it was to have neighbors.

Sometimes our lives were __47__; at others, we were killed with a __48__ “Bang, Bang!”. Even more dangerous were the arrows that occasionally came sailing __49__ the garden fence.
But we did not __50__ go in fear for our lives. The Robinsons were friendly and helpful and when we left for our holidays, we knew we had nothing to fear __51__our neighbors were around. We understood what it was like to have __52__ in the long, dull winter evening __53__ Mr Robinson would __54__ in for a cup of tea and chat; or when Mr. Robinson would __55__ over the fence and talk endlessly with father about gardening problems.
