[解析]
Hi, Janice,
It's been a month since I came to this new school and I really want∧ share with you some of the problems I have been experiencing. As I tell you last time, I made three new friend here. We hang out together during lunch and after school. We've been spending a lot of time sing in karaoke bars. It's been three Saturdays now and it really costs me many. And I started to see this as a time﹣wasting activity! In fact, I don't like to go anymore, so I'm afraid I'll lose their friendship. How do you think I should do? If you were me, would you talk to him? Please help with me and give me some advice.
详解:
1.want后加to 考查动词不定式.want后接动词时要用动词不定式作宾语.
2.tell改为told 考查时态.根据句中的状语last time,表明此处用一般过去时.
3.friend改为friends 考查名词复数.friend是可数名词,其前有数词three修饰时要用复数形式.
4.sing改为singing 考查动名词.spend time/money (in) doing sth.意为"花费时间(金钱)做某事",其中in可以省略.
5.many改为much 考查代词.根据语境,此处指花了"我"很多钱,应用much代指不可数名词.
6. started改为start.考查时态.结合前后内容可知这里说的是一般情况,因此用一般现在时.
7.so改为but 考查连词.上下句有转折关系,应用but.
8.How改为What 考查疑问词.do后缺少宾语,所以疑问代词用What,表示"所…的事情".
9.him改为them 考查代词.此处指作者的三个朋友,是复数概念,应用them.
10.去掉with 考查介词.help为及物动词,其后可直接跟宾语,不需要介词with.
