If you stop to think about it, the history of housework is the history of everything. Housework has changed an amazing amount in only the last hundred years or so. The invention of electricity was very important, and it led to the arrival of the washing machine, the vacuum cleaner, the dishwasher, and so on. Housework would have been much harder without them fifty years ago. It’s not just technology that’s different — these days, most husbands are expected by their wives to share the housework. Overall, then, we can see a great improvement in relation to housework, especially for women — although the environmental cost of modern housework is high.

Пояснение:

Housework has changed — используется Present Perfect, потому что речь идёт об изменении за период «за последние сто лет».

The invention of electricity — нужно существительное от глагола invent. Получается invention — «изобретение».

The arrival of the washing machine — нужно существительное от глагола arrive. Получается arrival — «появление».

Housework would have been much harder — конструкция would have been показывает, какой была бы ситуация в прошлом без этих изобретений.

Most husbands are expected — пассивный залог: «от большинства мужей ожидают».

A great improvement — после a great нужно существительное. Improve превращается в improvement — «улучшение».
