[解析]
Dear Jin Jing,
Your problem is∧common one among middle school students.Maybe the following advices can help you.First in all,believe in yourself.Your greatest problem is that you don't have self﹣confidence.The first thing you must do is to smile at your classmates.One smile speaks loud about your wish to make the friends than any word.Your smile will show that you are friendly to him.Next,trying talking with a student who is as shy as you or who share the same interest with you.You can discuss your studies with a classmate,and you can also talk about your hobbies as well.Unless someone is in trouble,you should be ready to help him or her.Once you have confidence,you can make as many friends as possibly.
详解:
1.is后面加a,考查冠词.后面的名词one是一个可数名词,使用冠词a修饰.
2.advices改为advice,考查名词的数.名词advice是不可数名词,没有复数形式.
3.in改为of,考查固定短语.固定搭配first of all最重要的.
4.loud改为louder,考查副词的比较级,后面有than,所以用比较级.
5.word改为words,考查词义辨析,word单词;words语言,此处为语言.
6.him改为them 考查代词 更加前后文可知,此处指的是和 classmates的交往,此处应该使用them来指代.
7.trying改为try,考查祈使句,祈使句是以动词原形开头.
8.share改为shares,考查主谓一致,定语从句的关系词who代替先行词a student,所以谓语动词用第三人称单数形式.
9.Unless改为If,考查连词,根据句意"如果别人有麻烦,你应该乐于帮忙.",用if表示假设.
10.possibly改为possible,考查固定搭配,根据短语"as…as possible尽可能地".
