读写任务（共1小题，满分25分）
阅读下面的书信，然后按照要求写一篇150词左右的英语短文。
Dear David,
I am writing you this email because you’re so busy every day with your studies and after-school activities that we seldom have chances to talk face-to-face. There is something that I am very worried about.
You have always been an active boy, willing to help others and always looking for an opportunity to try something new or learn something different. I think these are wonderful qualities but I am concerned that they may be affecting your studies. In the past three months alone you have joined at least four different student clubs. I see these activities taking up more and more of your time. You’re always discussing something with your classmates or surfing online. You’re also devoting less time to homework and even your teachers say you are looking very sleepy in class.
I know that these kinds of activities are fun and can help your development, but I think they have started to damage your performance at school. Please remember the most important thing at this stage of your life is your studies. Right now you should do your best in your examinations as it will give you more choices is your future. I beg you to focus on your main goal and not to throw away all your years of hard work
Your loving mother
