“very fast” shows the speed of running.
The beautiful flower in the garden
(花園里美麗的花 )
It tells us the flower is beautiful and where it grows.
A cute cat
(可愛的貓 )
Cute" describes the cat's feature, so it modifies "cat".
These word combinations with modifiers are called phrases—they make descriptions richer. Let's explore them today!
名詞短語 = 名詞 + 修飾詞(冠詞/形容詞等)
形容詞短語 = 形容詞 + 修飾詞(副詞等)
副詞短語 = 副詞 + 修飾詞(副詞等)

She thinks and speaks quite quickly.
I found most of my classmates and teachers friendly and helpful.
My favourite subject is English because my English teacher is really interesting.
We had a lot of fun playing basketball on the playground yesterday.
Read and Think
句子 1:The first week was a little confusing.
名詞短語:The first week
分析:以名詞 “week” 為中心詞,“The first” 是修飾詞(序數詞 + 定冠詞),共同構成名詞短語。
功能:在句中作主語,表明句子描述的對象是 “第一周”。
形容詞短語:a little confusing
分析:以形容詞 “confusing” 為中心詞,“a little” 是副詞性修飾詞,用于說明程度。
功能:在句中作表語,描述 “the first week” 的性質狀態,即第一周的感覺是 “有點令人困惑的”。
句子 2:She thinks and speaks quite quickly.
副詞短語:quite quickly
分析:以副詞 “quickly” 為中心詞,“quite” 是副詞修飾詞,用于加強程度。
功能:在句中修飾動詞 “thinks and speaks”,說明動作進行的方式,即 “思考和說話的速度相當快”。
句子 3:I found most of my classmates and teachers friendly and helpful.
名詞短語:most of my classmates and teachers
分析:以名詞 “classmates” 和 “teachers” 為中心詞,“most of my” 是限定性修飾詞。
功能:在句中作賓語,是動詞 “found” 的承受對象,表明 “我” 發現的對象是 “我的大多數同學和老師”。
形容詞短語:friendly and helpful
分析:由兩個并列的形容詞 “friendly” 和 “helpful” 構成,無額外修飾詞,屬于簡單形容詞短語。
功能:在句中作賓語補足語,補充說明賓語 “most of my classmates and teachers” 的性質,即他們 “友好且樂于助人”。
句子 4:My favourite subject is English because my English teacher is really interesting.
名詞短語:My favourite subject
分析:以名詞 “subject” 為中心詞,“My favourite” 是形容詞性修飾詞(物主代詞 + 形容詞)。
功能:作主語,表明句子描述的核心對象是 “我最喜歡的學科”。
名詞短語:my English teacher
分析:以名詞 “teacher” 為中心詞,“my English” 是限定性修飾詞(物主代詞 + 名詞作定語)。
功能:在原因狀語從句中作主語,說明從句描述的對象是 “我的英語老師”。
形容詞短語:really interesting
分析:以形容詞 “interesting” 為中心詞,“really” 是副詞修飾詞,用于強調程度。
功能:在原因狀語從句中作表語,描述 “my English teacher” 的性質,即老師 “非常有趣”。
句子 5:We had a lot of fun playing basketball on the playground yesterday.
名詞短語:a lot of fun
分析:以名詞 “fun” 為中心詞,“a lot of” 是數量限定性修飾詞。
功能:在句中作賓語,是動詞 “had” 的承受對象,表明 “我們擁有的是許多樂趣”。
副詞短語:本句時間狀語 “yesterday” 和地點狀語 “on the playground” 為介詞短語,非副詞短語,故無副詞短語。
Conclusions:
名詞短語:核心是名詞,前常接冠詞、形容詞、物主代詞等修飾詞,常作主語、賓語。
形容詞短語:核心是形容詞,前可接副詞修飾程度,常作表語、定語或賓語補足語。
副詞短語:核心是副詞,前可接其他副詞修飾程度,主要修飾動詞、形容詞或副詞,說明動作的方式、程度等。
1. 用“△”標出下列句子中的名詞短語:
① The old man walks in the park every morning.
② Her new dress looks very beautiful.
③ We bought three red apples in the shop.
practice
① The old man△ walks in the park△ every morning.
(解析:“The old man”中“man”是名詞,“The old”修飾;“the park”中“park”是名詞,“the”修飾)
② Her new dress△ looks very beautiful.
③ We bought three red apples△ in the shop△.
識別下列的短語類型
① a very tall building ( )
② runs extremely fast ( )
③ feels quite cold ( )
④ five lovely children ( )
⑤ speaks English very well ( )
① (名詞短語)
② (副詞短語)
③ (形容詞短語)
④ (名詞短語)
⑤ (副詞短語)
3. 用指定的短語完善下列句子:
① She sings.(加入副詞短語“very beautifully”)
② The cat is sleeping.(加入形容詞短語“so cute”)
③ He has a book.(加入名詞短語“an interesting story book”)
① She sings very beautifully.
② The cat is so cute when sleeping.
③ He has an interesting story book.
4. 改正錯誤:
① This is a book interesting very. → ____________________
② He speaks English good very. → ____________________
① This is a very interesting book.(形容詞短語語序:修飾詞+形容詞+名詞)
② He speaks English very well.(副詞短語語序:修飾詞+副詞,注意“good”需變為副詞“well”)
