阅读下面短文并根据短文后的要求回答问题（请注意问题后的词数要求）。
[1] Homestay is a great way to experience a new culture. As a volunteer you will get a new family to live with. Apart from their visits to tourist sites, most international volunteers remember their experiences in the homestay.
To help you with your homestay, here are a couple of tips.
[2] As a sign of kindness, carry a small gift to the family you are going to live with. It will make you look like a generous person and they will try to accommodate(提供住宿) you longer. People are all glad to be given gifts.
[3] As you will be living in a new home and culture, there are things that are different. There should be habits which could be new to you, like how they take a shower or how they raise kid. Do not judge them by their habits, but try to understand their culture. Soon you will find their ways are different but they also work.
[4] Don’t be the first one to wake up or the last one to wake up in the mornings. Wake up in time for breakfast and if possible try to help make breakfast. Some cultures find it __________________________ to still be in bed when everyone has got up.
[5] Be thankful for everything the family decides to give you or do for you. If the host mom wants to wash your clothes, just accept and be very grateful. When they bring food and any other things to you, make sure to thank them.
[6] Most volunteers stop communicating with the host family after they end their homestay. They may forget the host family. The better way is to keep up with the host family whenever you can. This way you would form a lifelong friendship, and the next time you go to that country you can stay with them again.
