How often... 句型：用来询问动作发生的频率。回答可以用频度副词或表示频率的短语，如 once a week（一周一次）、twice a month（一个月两次）等。
四、词语辨析
1、maybe/may be：
maybe 是副词，意为“也许，可能”，通常放在句首；
may be 是“情态动词 may + be 动词”结构，意为“可能是”，在句中作谓语。
例如：Maybe he is a teacher. He may be a teacher.
although/though/even though：三者都有“虽然，尽管”之意，引导让步状语从句。
although 和 though 较为常用，even though 语气稍强。
例如：Although/Though/Even though it was raining, we still went out.
such as/for example：都有“例如”之意。
such as 用来列举同类人或事物中的几个例子，后面不用逗号；
for example 一般只举同类人或事物中的“一个”为例，且用逗号隔开。
例如：I like sports, such as swimming, running and playing basketball. For example, I like swimming.

My Weekend Activities
On weekends, I have a variety of activities that keep me engaged and entertained.
On Saturday mornings, I usually get up early and go for a jog in the park. The fresh air and beautiful scenery help me start the day on a positive note. After that, I might help my parents with some household chores like cleaning the house or doing the laundry.
In the afternoon, I often meet up with my friends. We might go to the library and read books or study together. Sometimes we also play sports such as basketball or badminton. It's a great way to stay active and have fun at the same time.
On Sunday, I like to spend some quiet time at home. I might watch a movie or read a novel. I also make sure to review my schoolwork for the coming week. This helps me stay on top of my studies and be prepared for classes.
In conclusion, my weekends are filled with activities that balance fun and productivity. I look forward to each weekend as an opportunity to relax, learn, and have a great time.
