1. (2020八下·湛江开学考) 下面是一则对妈妈的调查结果。请仔细阅读该短文，根据所提供的信息，回答下面的问题。

As we all know, mothers are the greatest persons all over the world. They do all kinds of things for their families and their kids. And they have little time for themselves. But do you know how much time they spend on different kinds of things in their daily life? Here is the result of a new survey of 100 hard-working mothers which shows their daily timetable.

From the result we know that they spend about 70 hours a week doing chores and looking after their families. They spend more than ten hours a day cooking, cleaning the house, getting children ready for school and helping with homework. Cooking takes up about one hour and nine minutes a day. Doing the laundry takes about 61 minutes. Mothers also spend about 55 minutes getting children ready for school, about 53 minutes putting them to bed and about 47 minutes helping with homework.

However, mothers with children under 16 get less than six hours' sleep at night.83% are not happy because they have less than an hour of their own time every day. Only 17% are happy with this kind of life.

So mothers are busy and tired every day. All of us should do something to show our love to our mothers.
