本文主要介绍了几种使自己生活更有意义的方法。
1. G 选项G “ 有许多方法能丰富你的生活和增加生活的意义”与第一句“当你做日常工作时，你可能偶尔会想知道如何使你的生活更有意义”是承接上句的关系，与空格后“以小的改变开始”是启下的关系。因此选G。(承上启下)
2. C 选项C“是“照顾好自己”。根据代词是语篇衔接手段之一，空格后的it指代空格内容 “照顾好自己”。空格后的句子意思是“照顾好自己听起来有点自私，但照顾自己能使生活更有意义”。选项C起到总起本段的作用。(总—分关系)
3. E 选项E“多陪朋友和家人”。空格后句意是 “和对生活有积极态度的朋友交往”，本段最后一句是“去父母的住处看望他们”可知本题选E。选项E起到总起本段的作用。(总—分关系)

五、短文改错
Like most people, there was a time that I
dreamed of being an excellent student in my
English after entering senior middle school, but
my English was very poor then. To catch up my
classmates, I followed my friend advice and took
some measures.
For an instance, I made pen-friends with
some foreign students so as to practise my
speaking English and improve my written
English.
Although some of my classmates often went to
the movie in the evening, I seldom took apart
in such activities. Instead, I set down my spare
time to concentrate on my English and win the
Final English Speech Contest around the city
this term, realizing my dream.
本文讲述了作者在上高中后经过自己的努力，最终提高了自己的英语成绩，并在英语演讲比赛中获胜。
1. that→ when 句型there was a time when…中，when引导定语从句，指代先行词time，在从句中充当时间状语从句。
2. but→ though 虽然前后句子是转折关系，但强调的内容是前者，应该是“自考入高中之后，我曾一度想成为一名英语成绩优秀的学生，虽然当时的英语很糟糕。”
3. 在catch up后加上with 因catch up with sb.是固定搭配，意为“赶上，追上”。
4. friend→ friend’s 表示“朋友的(建议)”，用名词所有格。
5. 去掉instance前的an 因for instance是固定搭配。
6. speaking→ spoken 表示“英语口语”应是spoken English。
7. movie→ movies 因go to the movies(看电影)是固定搭配。
8. apart→ part 因take part in表示“参加，参与”；take sth. apart 意为“拆开”。
9. down→ aside 因set down 是“放下；记下”的意思；set aside 才是“省出; 抽出（时间）”的意思。
10. win→ won 全文都是对高中学英语的回忆，故都使用过去时态。
