PET 专项突破

Part 6:开放填空(语法总检验)

13 分钟

题型:一篇约 150 词的短文挖 6 个空,不给选项,每空只填一个词

和 KET 的开放填空相比,PET 挖的词从「基础小词」升级到「语法结构词」——它其实是第三章语法的直接检验。


PET 特有的高频答案

类别 常见答案 触发信号
关系代词 who / which / that / whose / where 空格前是名词,后面是一个从句
连词 although / because / so / while / until / unless 两个句子之间的逻辑关系
比较结构 than / as / more / most / the 有比较级或最高级
被动的 be was / were / been / being 后面是过去分词
完成时的 have have / has / had 后面是过去分词
条件句 if / unless / would 假设语境
不定式 / 动名词 to 空后是动词原形
数量词 much / many / few / little / enough / both 修饰名词
代词 it / one / another / each other 指代前文
介词 in / on / at / of / for / with 固定搭配

六个「看到就填」的信号(PET 版)

名词 + ____ + 动词(从句) who(人)/ which / that(物)
____ + 过去分词 was / were / been / has / had
比较级 + ____ than
as + 形容词 + ____ as

实战演示

Many people say that learning a language (1)____ difficult, but I don't agree. When I was ten, I started learning French, (2)____ was much easier than I expected. The most important thing is (3)____ practise every day, even (4)____ only for ten minutes. My teacher, (5)____ has taught for twenty years, says that students who give up (6)____ the first month never succeed.

答案与思路

  1. is——主语 learning a language 是单数(动名词作主语),谓语用 is
  2. which——前面是一整件事(学法语),用 which 引导非限制性定语从句
  3. to——The most important thing is to practise(不定式作表语)
  4. if——even if 即使(固定搭配)
  5. who——先行词是 my teacher(人)
  6. in——in the first month(在第一个月里)

注意第 1 题:动名词短语作主语时当单数看,这是 PET 常考的细节。


三条纪律

  1. 只填一个词。 想填 in order to、has been,说明判断有误(不过 been 单独填是可能的)。
  2. 拼写必须对。 although、because、which 拼错不给分。
  3. 注意形式:填动词时要考虑时态和单复数(is 还是 are、has 还是 have)。

这一题的备考方法

不是刷题,是补语法。 Part 6 挖的每一个空背后都是一条语法规则:

  • 填不出 who/which → 定语从句没学好
  • 填不出 was/been → 被动语态没学好
  • 填不出 than/as → 比较结构没学好

所以第三章才是这一题的真正复习材料。

练习:把上面那篇短文的答案遮住,隔天再做一遍,并说出每个空的语法依据。

小纸条

PET 的 Part 6 相比 KET 挖的词有什么升级?填不出 who/which 说明哪一块语法没学好?
