答题技巧
一、通用 4 步解题法
1.定时态:圈出句中时态标志词(如 yesterday, every day, now, tomorrow 等),快速判定句子时态,匹配对应转换规则。
2.定结构:判断句子核心结构(be 动词、情态动词、实义动词作谓语),选择对应的转换方法。
3.变形式:严格按照规则变形,注意动词形式还原、人称转换、some 变 any、名词单复数等细节。
4.查格式:收尾检查句首单词首字母大写、句末标点正确、单词拼写无误。
二、答题技巧

a.含 should 的句子变否定:should 后直接加 not,缩写为 shouldn't,后接动词原形。
b.实义动词作谓语的一般现在时,主语是第三人称单数时,变否定用 “doesn't + 动词原形”;变一般疑问句用 “Does + 主语 + 动词原形 + 其他?”。
c.对身体状况提问用 What's wrong with...?;对建议内容提问用 What should...do?。
Unit4 Neighbourhood(There be 句型与现在进行时专项)
