The charts below show the changes in ownership of electrical appliances and amount of time spent doing housework in households in one country between 1920 and 2019. Summarize the information by selecting and reporting the main features, and make comparison where relevant. Write at least 150 words.

There are two line charts that respectively illustrate the trends of the percentage of

households

with electrical appliances and the number of hours of housekeeping per week, per household during the period of 1920 to 2019 in a particular country.

According to

the first

chart

, citizens generally rely on three electrical

machines

to help with their housework，including washing

machines

,

refrigerators

and

vacuum

cleaners

. Looking from an

overall

perspective, it is apparent that there was a dramatic increase in the proportion of

households

who owned electrical appliances from 1920 to 2019,

on the contrary

, the time that every week’s housework required for each household experienced a relatively steady decline during the same time.There is

machines

and

vacuum

cleaners

was the same at 70%, after that, the proportion of

vacuum

cleaners

and

refrigerators

respectively soared by 30% and 20%.What is more, they all peaked at 100% and remained unchanged between 2000 and 2019, which left washing
