“be+形容词+介词”是英语中高频且实用的固定结构,通过形容词与特定介词的搭配,精准表达”主语与其他事物的关系”(如所属、缘由、态度等)。这类结构看似零散,实则有规律可循,是考试中的基础考点与易错点。以下从核心分类、学习要点、高频考点三方面解析。

"be+形容词+介词"结构:从固定搭配到语境应用的学习要点

一、核心分类:按语义功能梳理8类高频搭配

“be+形容词+介词”的核心是”形容词决定介词”,不同形容词因语义倾向,固定搭配特定介词,常见分类如下:

1. 表”态度与情感”

– be afraid of(害怕…):She is afraid of snakes.(她怕蛇。)

– be fond of(喜爱…):He is fond of reading.(他喜爱读书。)

– be proud of(为…自豪):They are proud of their son.(他们为儿子自豪。)

– be interested in(对…感兴趣):I am interested in music.(我对音乐感兴趣。)

2. 表”缘由与目的”

– be late for(因…迟到):She was late for school.(她上学迟到了。)

– be ready for(为…做好准备):We are ready for the exam.(我们为考试做好了准备。)

– be famous for(因…著名):This city is famous for its scenery.(这座城市因景色著名。)

3. 表”关系与所属”

– be good at(擅长…):He is good at math.(他擅长数学。)

– be weak in(在…薄弱):She is weak in physics.(她物理薄弱。)

– be made of(由…制成,能看出原材料):The table is made of wood.(这桌子是木头做的。)

– be made from(由…制成,看不出原材料):Paper is made from wood.(纸由木头制成。)

4. 表”方位与位置”

– be close to(靠近…):The school is close to my home.(学校离我家近。)

– be far from(远离…):The village is far from the city.(村子离城市远。)

– be next to(紧挨着…):My seat is next to his.(我的座位紧挨着他的。)

5. 表”责任与义务”

– be responsible for(对…负责):Teachers are responsible for students.(老师对学生负责。)

– be ready to(准备好做…):She is ready to help others.(她乐于助人。)

6. 表”符合与一致”

– be similar to(与…类似):Her hobby is similar to mine.(她的爱好和我类似。)

– be different from(与…不同):This book is different from that one.(这本书和那本不同。)

7. 表”依赖与独立”

– be dependent on(依赖…):Children are dependent on their parents.(孩子依赖父母。)

– be independent of(独立于…):She is independent of her family.(她不依赖家人。)

8. 表”忙于与空闲”

– be busy with(忙于…):He is busy with his work.(他忙于工作。)

– be free from(免于…):We are free from homework today.(我们今天没作业。)

二、学习要点:3大核心原则

1. 固定性:介词不可随意替换

形容词与介词的搭配是长期使用形成的固定结构,不可凭中文语感更改。

– 错:be interested with(应为in);be good in(应为at)

– 对:be interested in;be good at

2. 语义关联:通过形容词记介词

介词的选择与形容词的核心语义相关:

– 表”指向/对象”多用in/of(如interested in,afraid of);

– 表”技能/擅长”多用at(如good at,skilled at);

– 表”比较/差异”多用to/from(如similar to,different from)。

3. 语境变化:注意主语与介词后宾语的关系

结构中”介词+宾语”是对主语的补充说明,需确保逻辑合理:

– 例:be proud of后接”自豪的对象”(如He is proud of his success. 成功是自豪的对象);

– 误:He is proud of happy.(of后需接名词/代词,不可接形容词)

三、高频考点与典型错误

(一)高频考点5例

1. She is good ______ playing the piano.(答案:at——固定搭配be good at)

2. This song is popular ______ young people.(答案:with——be popular with 受…欢迎)

3. He is late ______ the meeting again.(答案:for——be late for 因…迟到)

4. The story is similar ______ the one I heard.(答案:to——be similar to 与…类似)

5. They are proud ______ their achievements.(答案:of——be proud of 为…自豪)

(二)典型错误分析

1. 介词混淆:

错:He is afraid from dogs. → 对:He is afraid of dogs.(afraid固定搭配of)

2. 遗漏介词:

错:She is interested music. → 对:She is interested in music.(interested后必须加in)

3. 误用形容词后接不定式:

错:He is good to swim. → 对:He is good at swimming.(good表”擅长”时接at+动名词,不接不定式)

4. 混淆be made of与be made from:

错:The wine is made of grapes.(能看出原材料,应为of);The bread is made of wheat.(看不出原材料,应为from)

四、记忆口诀

“be加形,介相随,固定搭配记心扉;

afraid of, good at,类似similar to对;

迟到late for, 自豪proud of,语义关联不混淆。”

“be+形容词+介词”结构的核心是”固定搭配+语义逻辑”,通过分类记忆(如态度类、关系类)和真题练习,可快速掌握高频搭配,避免常见错误,让表达精准规范。
