【知识点一：英语语法填空】
在英语学习中，语法填空是常见的练习题型，旨在测试学生的词汇掌握、语法理解和上下文理解能力。题目中的单句语法填空涉及了词性转换、非谓语动词、形容词与副词的比较级以及固定搭配等知识点。
1. "Join a ________(guide) bike tour" 中填入 "guided"，表示“有导游的”，这里将动词 "guide" 转换成形容词修饰 "bike tour"。
2. "using ________ (recycle) and made materials" 中填入 "recycled"，表明材料是“回收再利用的”，动词 "recycle" 被转化为过去分词作定语。
3. "compared with ________(previously) studies" 中填入 "previous"，形容词修饰 "studies"，表示“先前的研究”。
4. "Though ________(lack) natural resources" 中 "lack" 作为伴随状语，用其现在分词形式 "lacking" 表示主动关系。
5. "The ____________(surround) which a child grows up in" 中填入 "surroundings"，名词 "surroundings" 指的是“环境”。
6. "fashion is ____________(constant) changing" 中 "constant" 转为副词 "constantly"，修饰动词 "changing"。
7. "make a few ____________(adjust) to the new situation" 中填入名词 "adjustments"，表示“做出一些调整”。
8. "make no ____________(impress) on the child" 中 "impress" 转换为名词 "impression"，构成短语 "make no impression on sb."，意为“对某人没有影响”。
9. "_______(instant) realizing it was one of the many factory robots" 中 "instant" 前缀转化为副词 "instantly"，表示“立即地”。
10. "_______(know) your strengths and weaknesses" 中 "know" 作主语，需变为动名词 "knowing"。
【知识点二：英语单句改错】
这类题目主要考察学生对英语句子结构、时态、搭配等方面的掌握。
1. "We are reliably informed that David has been back to his feet"，应改为 "We are reliably informed that David is back on his feet"，"be back on one's feet" 是固定短语，表示“恢复健康”。
2. "she had the impression she had seen most of the guests before"，应在 "impression" 后加上 "that" 引导同位语从句。
3. "there'd be nothing leaving for me to do"，应改为 "there'd be nothing left for me to do"，"left" 作为过去分词在此处作后置定语。
4. "lose sight the importance of education"，应在 "sight" 后加上 "of"，构成短语 "lose sight of sth."，意为“忽视”。
5. "the thief slid the room"，应改为 "the thief slid into the room"，"slide into" 表示“悄悄进入”。
6. "cannot tolerate cheat in exams"，应改为 "cannot tolerate cheating in exams"，"tolerate" 后接动名词作宾语。
7. "hard to get along"，应改为 "hard to get along with"，"get along with sb." 表示“与某人相处”。
8. "as though she is a stranger"，由于 "as though" 引导的方式状语从句通常用虚拟语气，应改为 "as though she were a stranger"。
9. "Royers took on painting for a while"，应改为 "Royers took up painting for a while"，"take up" 表示“开始从事”。
10. "As far as I'm conce"，应为 "As far as I'm concerned"，表示“就我而言”。
这些练习题涵盖了高中英语复习中重要的语法点，对于提高学生的英语综合能力具有很大帮助。通过这样的练习，学生可以更好地理解和运用英语语法，为高考做好充分准备。
