Dear Peter,I’m writing to tell you about what happened to me last week while I 1) was visiting my aunt who lives by sea. One afternoon I 2) was taking her dog for a walk by the cliffs when I 3) noticed a girl who 4) was climbing a tree by the edge of the cliff. As she 5)was hanging there, the branch suddenly 6) broke and the girl 7) fell over the edge. I 8) ran to the edge, but although the girl 9) was shouting for help, I 10) wasn't able to see her. I 11) was thinking about what to do when a man 12) came along  the cliff path. I 13) explained what had happened and while he 14)went for help I 15)was talking to the girl. Well, everything 16) ended happily. The girl was rescued and her parents17) thanked me by giving me a large bunch of flowers. The story 18) was in the newspaper too! That’s all my news – write and tell me yours soon.

Зад.1  watch-часы (наручные), один экземпляр..  watches - это несколько часов. Специфично слово - deer (олень, олени). Множественное число  этого слова совпадает с единственным, нет окончания (e)s. Еще слово teeth - мн. число образуется изменением корня (tooth-teeth, зуб-зубы)

Объяснение:

Правила произношения и написания окончаний существительных во множественном числе зависят от исходного слова. Общее правило - конечные звонкие согласные не оглушаются, то есть произносятся как z-iz. Вот тут коротко и ясно: https://engblog.ru/plural-of-nouns
