1．在donate之前加to 考查固定短语"call on sb．to do sth．"意为：号召某人做某事，呼吁某人做某事；本句的意思是：我们的老师号召每个人都捐一本书；故在donate之前加to；
2．去掉of 考查连词because与固定短语"because of"的用法区别；
"because of"意为：因为，由于；其后应接单个的单词或短语；because其后接句子；由于此处because之后是一个句子，故去掉of；
3．将Read改为Reading 考查动名词 此处在句中作主语，表示具体的动作；故用动名词Reading；
4．将making改为make 考查动词的形式 此处与 broaden our horizon一起在句中作help的宾语；故用动词原形make；
5．将colorfully改为colorful 考查固定结构"make sb．/sth．+形容词"意为：使某人/某物怎么样；这里指的是：使得我们的课外活动更加丰富多彩；故用colorful；
6．将that改为which 考查关系代词 根据句意以及此处的逗号可知，本句是非限定性的定语从句；此处指代的是前面的句子，在从句中作主语；由于关系代词that不能用于非限定性的定语从句中，故用关系代词which；
7．将troubles改为trouble 考查名词的单复数 由于trouble在这里意为"麻烦"是不可数名词，不能加s；故用trouble；
8．将or改为and 考查连词 本句的意思是：首先，它介绍了不同的英语写作类型以及一些写好英语作文的技巧；此处表示并列关系，故用and；
9．将give改为given 考查过去分词 此处在句中作定语修饰名词tips，由于动词give与该名词构成了动宾关系；意为：由专家给出的一些好的建议；故用过去分词given；
10．将about改为with 考查固定短语"help sb．with sth．"意为：帮助某人做某事；此处的意思是：所以我还希望它能帮助我的同学们把英语写作搞好；故用with．
