我们在朗读英语或⽤英语交谈时,并不是句⼦中的每个词都读得⼀样响亮,⼀样清楚,⽽是有些词读得或说得⼜轻⼜快,⽽且较为含
糊,有些词则读得或说得⼜重⼜慢,⽽且较为清晰。

那些读得或说得响亮⽽清晰的词就是句⼦重⾳所在。

句⼦重⾳的功能
1. 体现句⼦的节奏感和韵律感；
2. 突出重点, 使听者更容易理解。

哪些词在句⼦中需重读？
⼀般来说, 在句⼦中需重读的词都是实词, ⽐如: 名词、动词、形容词、副词、数词、代词等。

不重读的多为虚词，⽐如: 冠词、连词、介词、感叹词等。

如:
1. The streets are wide and clean. (这句话中的streets是名词,wide和clean 是形容词, 它们都要重读; the, are, and不重读。

)
2. I am so glad to see you again. (这句话中的so, glad, see, again要重读, ⽽I, am, to, you不重读。

)
有时候虚词也要重读, 以下⼏点需注意:
1）强调或突出某个虚词或be动词时, 应将其重读。

如:
We saw him playing by the river. (这句话中的we和him⼀般不重读,但为了表⽰强调也可以重读。

⽐如, 如果we重读, 则强调
是“我们”⽽不是别⼈看见。

)

On my way to school, my bike was broken. (这句话中的on 在句⾸应重读。

)
3）be动词及助动词和not结合时要重读。

I’m sorry I can’t do that. (这句话中的can’t要重读。

─Are you a student? ─Yes, I am. (这⾥的am要重读。

) 注意: 上⽂刚出现过的并且重读的单词, 第⼆次提到时⼀般不再重读，如:─How many boys are there in the room?
─There are twenty boys in it. (问句中的boys 要重读, 但答语中的boys 不重读。

Part C Writing
Writing for General Purposes: Types of Writing (4): Description
Writing Strategy
A descriptive essay is a text that presents a detailed image of a person, place, or thing. This is done through the use of descriptive language—adjectives and adverbs—and the incorporation of images that incorporate several of the body’s senses. A descriptive essay is typically a form of personal writing because it presents its description through the perception of a single person—typically the writer. However, a descriptive essay differs from a narrative essay because its main focus is on
describing a person or thing, not on telling a story.
The point of a descriptive essay is to present a specific image in the reader’s mind—to allow the reader to see a scene or thing as the writer does. To do this, a writer must be very precise and detailed. An important aspect of descriptive essay writing is the order in which the writer chooses to describe a thing or scene. The image is usually built from general to specific, which is easier for the mind’s eye to imagine. A good descriptive essay will also attempt to incorporate as many senses as possible in order to present the most complete form of the entity being described.。
