答案：[解题导语]本文主要讲述了老师和学生对发博客的看法。
1．nticed 解析：考查动词时态。通读全文可知，故事发生在过去，故用动词的一般过去时。
2．with 解析：考查介词。share sth. with sb.意为“与某人分享某物”，为固定搭配，故用介词with。
3．truly 解析：考查副词。修饰动词应用副词，故用副词truly修饰动词enjyed。注意true变副词时去掉字母e加ly。
4．a 解析：考查冠词。discussin在此处表示具体概念，且第一次在语境中出现，故用不定冠词a修饰。
5．creative 解析：考查形容词。hw修饰形容词或副词。由下文的be可知，此处应用形容词作表语，故用creative。
6．what 解析：考查名词性从句。空处引导主语从句，在从句中作主语，表示物的概念，what符合语境。
7．suggestins 解析：考查名词。her是形容词性物主代词，修饰名词，故用名词形式。此外，suggestin是可数名词，由Many f可知，应用复数形式。
8．urselves 解析：考查代词。由句子主语we可知，此处应用反身代词，表示放松自我。
9．writing 解析：考查非谓语动词。write和从句的谓语wrks之间没有连词，故用非谓语动词。其与主语he构成逻辑上的主谓关系，故用现在分词作伴随状语。
10．t finish 解析：考查非谓语动词：have time t d sth.意为“有时间做某事”，为固定搭配，不定式作宾语补足语。
