Grandparents are respected in many human societies. But telling stories about old times and overfeeding grandchildren seem like human qualities. Are these classic grandparent behaviors really limited to humans?

Do any animals know their grandparents the way people do?

For most species on Earth, the answer is certainly " No" . " Usually, there aren't grandparents around anymore when an animal is born,"  said Mirkka Lahdenpera, a biologist at the University of Turku in Finland. " Even if an animal's life span does overlap (重叠) with its grandparents', most species spread out to avoid competing for resources, so the chance of running into a grandparent is slim." 

But there are a few clear exceptions, primarily among mammals (哺乳动物) that live in close social groups. In troops of langur monkeys in India, older females lived together with their daughters and grandchildren. The grandmother langurs defend the group's babies against attacks and even give their own grandchildren special treatment.

Many whale species, too, travel in family groups that include both grandmothers and grandchildren.

Elephant herds are also famously matriarchal. They are led by a grandmother, who can live to around 80 years old, and are generally made up of her daughters and their young. The females in a herd form close bonds and work together to raise their young.

Lahdenper found that the babies of young mothers were eight times more likely to survive if their grandmothers lived near them than if they didn't. When the young mothers were older and more experienced at raising babies, this beneficial grandmother effect disappeared even if the actual grandmothers were still around.

Indeed, most evidence for the benefits of grand parenting comes from mammals. But in 2010, researchers found that in troops of insects called gall-forming aphids, older females defend their relatives after they've stopped reproducing (繁殖).

And what about grandfathers? Studies of humans in recent decades have shown that a living grandfather can improve a person's mental health and other indicators of well-being. But there's no evidence of that in the animal kingdom. Male animals rarely socialize with their own children, let alone any grandchildren.

There is always a discussion about whether you should get your kids to do chores at home or not. However, getting kids to do housework is really good for children in many ways. So I find it hard to understand why you wouldn't get them to do chores.

The most important reason is that getting children to do chores teaches them a lot of life skills. They need to know how to clean, how to cook, how to shop, etc. It is, however, one of the things that schools don't teach completely, so it is one of the main parts of learning that parents should provide for children before they leave home.

Children like to feel proud about their achievements. Making them help around the house can really help to give them a sense of pride. Also, giving them praise for helping will make them want to do more. They will feel happy to be able to help around the house.

Giving your children a job to do or an area in the house to look after will help them learn how to be responsible in their future life. They will see the benefit (益处) of keeping things organized, clean and tidy—and also be more thankful for what you do for them as they grow up.

Planning is a life skill that can be got from helping around the house. As children get older, you can start to teach them how to understand the needs of themselves and others and plan by themselves. For example, if they help with the washing, let them make sure that they do it in time. They may start to plan ahead.

All these reasons for getting kids to help around the house mean that they'll grow up with a great set of skills that can be good for them throughout their lives. Why not get started today?

There is a Chinese idiom(习语)" taolimantianxia", referring to a teacher who has taught so many students that they spread across the country like peach and plum(李子) trees. Why are students compared to these two types of trees?

The id iom comes from Zizhi, an official( 大臣) who lived in the state of Wei during the Spring and Autumn Period(BC770-BC476). Zizhi was a knowledgeable person. But he was not well liked by the king at the time, so he had to leave his state. To make a living, he opened a private school and started to teach students.

As a teacher, Zizhi was kind and wise. He chose students regardless of(不论) their wealth or social status(社会地位). He often pointed at a peach and a plum tree in his yard when asking his students to work hard." You should become a useful person and do work to benefit(使受益) society, just like when the peach and plum trees bloom and yield(产出) fruit," he said.

Keeping these words in their minds, many of Zizhi's students went on to different places around the country, achieving great things along the way. They would plant peach and plum trees to show their respect for their teacher.

When Zizhi traveled around the country and saw his students and the trees they planted, he was very pleased." My students are like peach and plum trees. They are everywhere, and they have achieved great results."

Since then," peach and plum trees" has been used to refer to students who have been successful in their post- study careers.

There are a great number of cool things in our modern society. They can make our life a little bit easier and much more fun than before. Let's take a look.
