He wandered aimlessly from one country to another 1 before finally settling down in Australia, 2 where he trained AS an electronics engineer. He established HIS own business but it called for so much work that marriage was out of the 3 question.
His retirement suddenly made him realise how lonely he was and he decided to 5 take up a hobby. Whit his interest in electronics, amateur radio seemed a natural choice. He installed his own equipment and obtained a license and his call sign, which is the set of letters and numbers used to identify oneself when making radio contact 6 with other radio amateurs all around the world.
Soon Henry had a lot of contacts in far-off places. One in particular was a man in California with 7 whom he had much in common. One night the man in California made to mention the village in Europe he had come from. Suddenly, Henry realised that this man was in fact his younger brother, Peter. At first, the two brothers were at a 8 loss for words but then little by little they filled 9 in the details of their past lives and not long afterwards Henry Vincent flew to California to 10 be reunited with his brother.

Read the following passage and mark the letter A, B, C or D to indicate the correct answer to each of the questions from 43 to 50.

     Let children learn to judge their own work. A child learning to talk does not learn by being corrected all the time. If corrected too much, he will stop talking. He notices a thousand times a day the difference between the language he uses and the language those around him use. Bit by bit, he makes the necessary changes to make his language like other people's. In the same way, children learn all the other things they learn to do without being taught - to talk, run, climb, whistle, ride a bicycle - compare their own performances with those of more skilled people, and slowly make the needed changes. But in school we never give a child a chance to find out his mistakes for himself, let alone correct them. We do it all for him. We act as if we thought that he would never notice a mistake unless it was pointed out to him, or correct it unless he was made to. Soon he becomes dependent on the teacher. Let him do it himself. Let him work out, with the help of other children if he wants it, what this word says, what the answer is to that problem, whether this is a good way of saying or doing this or not.

     If it is a matter of right answers, as it may be in mathematics or science, give him the answer book. Let him correct his own papers. Why should we teachers waste time on such routine work? Our job should be to help the child when he tells us that he can't find the way to get the right answer. Let's end all this nonsense of grades, exams, and marks. Let us throw them all out, and let the children learn what all educated persons must someday learn, how to measure their own understanding, how to know what they know or do not know.

     Let them get on with this job in the way that seems most sensible to them, with our help as school teachers if they ask for it. The idea that there is a body of knowledge to be learnt at school and used for the rest of one's life is nonsense in a world as complicated and rapidly changing as ours. Anxious parents and teachers say, "But suppose they fail to learn something essential, some¬thing they will need to get on in the world?" Don't worry! If it is essential, they will go out into the world and learn it.

 

What does the author think is the best way for children to learn things?
