05 语法精讲与考点梳理
考点1:宾语从句的基本概念
【定义】宾语从句是在主句中充当宾语的句子,通常跟在及物动词、介词或某些形容词后面。
【用法分类】
1. that从句
跟在 think, believe, hope, agree, feel, hear, see, know, find, learn, promise 等动词后面。
例句:I think (that) I’ll have some grilled fish.
翻译:我想我会点一些烤鱼。
2. wh从句
跟在 wonder, explain, discuss, remember, forget, understand, know, ask, show 等动词后面。
例句:I wonder what we should order today.
翻译:我想知道我们今天应该点什么。
【结构公式】
主语 + 动词 + (that / wh-) + 宾语从句
考点2:that从句的用法
【定义】that从句用来陈述事实、表达观点或信念。that 在口语中常省略。
【常用动词】
think, believe, hope, agree, feel, hear, see, know, find, learn, promise, say, tell
【结构公式】
主语 + 动词 + (that) + 主语 + 谓语 + 其他.
【要点详解】
that 在口语中通常可以省略。
从句用陈述句语序。
that从句可以表达陈述事实、观点、信念等。
【例句】
✅ I think (that) I’ll have some grilled fish.
✅ The doctor said (that) I needed to lose weight.
✅ Are you sure (that) you want to order that much?
考点3:wh从句的用法
【定义】wh从句由疑问词(what, which, who, whose, when, where, why, how)引导,在句中作宾语。
【常用动词】wonder, explain, discuss, remember, forget, understand, know, ask, show, tell
【结构公式】主语 + 动词 + 疑问词 + 主语 + 谓语 + 其他.
【要点详解】
wh从句用陈述句语序,不用疑问句语序。
疑问词本身在从句中充当成分。
⚠️ 不能说:I wonder what should we order.(语序错误)
【例句】
✅ I wonder what we should order today.
✅ I don’t know why I like meat so much.
✅ Can you explain how we can eat more healthily?
考点4:否定转移
【定义】当主句动词是 think, believe, suppose, imagine 等表示“认为”的动词时,否定词通常转移到主句,而从句用肯定形式。
【结构公式】主语 + don’t / doesn’t + think / believe + (that) + 从句(肯定形式)
【要点详解】
否定的是从句的内容,但否定词放在主句。
这是英语中的习惯用法。
【例句】
✅ I don’t think (that) it’s a good idea to force children.(我认为强迫孩子不是好主意。)
✅ She doesn’t believe (that) he will come.(她相信他不会来。)
考点5:宾语从句的语序
【定义】宾语从句必须使用陈述句语序,即“主语 + 谓语 + 其他”,不能使用疑问句的倒装语序。
【结构对比】
直接问句
宾语从句
What should we order?
I wonder what we should order.
Why do I like meat so much?
I don’t know why I like meat so much.
