　　2．[2015·湖南高考]You have to know ________ you're going if you are to plan the best way of getting there.

　　PartⅡ　语篇真题演练

　　阅读下面材料，在空白处填入适当的内容(1个单词)或括号内单词的正确形式。

　　[2016·昆明调研]

　　During a recent

　　Senior Three

　　English

　　lesson, the teacher __41__ (notice)

　　Xiao Ming,

　　a student,

　　busily typing messages on her cellphone. To the teacher's surprise, Xiao Ming wasn't just texting her friends the latest small talk. She was blogging about what she was learning in the classroom, sharing her opinions __42__ her classmates. She said she __43__ (true)

　　enjoyed doing that.

　　The case caused __44__ heated discussion among teachers and students citywide. Miss Li, another English teacher said, “I am amazed at how __45__ (create) the students can be when writing on their blogs. To me it's a great way for students to improve their writing skills while writing about personal feelings and experiences.” But __46__ made other teachers worried was the blog－addiction which may disturb the students' study.,Step 1：通读全文，掌握主旨大意。

　　本文讲述了老师和学生对发博客的看法。

　　Step 2：逐题解答，确定答案。

　　41．noticed。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式形式。

　　42．with。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。

　　43．truly。考查副词。修饰动词应用副词，故用副词truly修饰动词enjoyed。

　　44．a。考查冠词。discussion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。

　　45．creative。考查形容词。how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。

　　46．what。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。A supporter and classmate of Xiao Ming said，“We love her blog! We all read it each day and can't wait to see what she writes about next.

　　Many of her __47__ (suggest) on study really help to encourage us.

　　And we can relax __48__ (we) while reading her blog.” Another student blogger admitted that he often works late into the night, __49__ (write)

　　his blog. He said,

　　“Sometimes I don't even have time __50__ (finish) my homework. I can't help myself. I really have a lot to say. ”

　　47.suggestions。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，suggestion是可数名词，由Many of可知，应用复数形式。

　　48．ourselves。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。

　　49．writing。考查非谓语动词。write和从句的谓语works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。

　　50．to_finish。考查非谓语动词。have time to do sth.意为“有时间做某事”，为固定搭配，不定式作宾语补足语。

　　Step 3：代入验证。

　　需考虑语法结构正确且语义符合逻辑，语法结合语义才能确保万无一失。
