Question

【題目】Making Music with Water

Have you ever tried making music with glasses or bottles filled with water? I bet your favorite band hasn’t. Experiment with your own special sounds by turning glasses of water into instruments, make some cool music and find out how it works.

What you’ll need:

Five or more drinking glasses or glass bottles.

Water.

Wooden stick such as a pencil.

Instructions:

Line the glasses up next to each other and fill them with different amounts of water. The first should have just a little water while the last should be almost full, and the ones in between should have slightly more than the first.

Hit the glass with the least amount of water and watch the sound, then hit the glass with the most water, which makes the higher sound?

九年級(jí)英語(yǔ)試題卷(第3頁(yè),共8頁(yè))

Hit the other glasses and see what noise they make. See if you can get a tune going by hitting the glasses in a certain order.

What’s happening?

Each of the glasses will have a different tone when you hit with the pencil. The glass with the most water will have the lowest tone while the glass with the least water will have the highest. Small vibrations are made when you hit the glass, and this creates sound waves which travel through the water. More water means slower vibrations and a deeper tone.

【1】How many glasses or bottles are needed in the experiment according to the passage?

A. Two. B. Three. C. Four. D. Five or more.

【2】What can we get from the experiment in the passage?

A. Light. B. Music. C. Water. D. Glasses.

【3】Which glass can have the lowest tone in the experiment?

A. The glass with no water. B. The glass with the most water.

C. The glass with the least water. D. All the glasses.

【4】What does the underlined word “vibrations” mean?

A. 破碎 B. 響聲 C. 震動(dòng) D. 裂紋

【5】Where may the passage come from?

A. TV program. B. Storybook.

C. Science book. D. Advertisement.

Answer 1

【答案】

【1】D

【2】B

【3】B

【4】C

【5】C

【解析】本文介紹了人們用裝有水的玻璃杯當(dāng)作樂(lè)器來(lái)進(jìn)行敲擊，產(chǎn)生不同的聲調(diào)，構(gòu)成音樂(lè)的實(shí)驗(yàn)。在試驗(yàn)中人們發(fā)現(xiàn)敲擊裝有最多的水的玻璃杯，產(chǎn)生最低的聲調(diào)，敲擊裝有最少的水的玻璃杯，產(chǎn)生最高的聲調(diào)。

【1】D

細(xì)節(jié)理解題。根據(jù)Five or more drinking glasses or glass bottles. 可知這個(gè)實(shí)驗(yàn)中需要五個(gè)或更多的玻璃杯，故選D。

【2】B

推理判斷題。根據(jù)Experiment with your own special sounds by turning glasses of water into instruments, make some cool music and find out how it works.可知我們從這個(gè)實(shí)驗(yàn)中可以聽(tīng)到音樂(lè)，故選B。

【3】B

細(xì)節(jié)理解題。根據(jù)The glass with the most water will have the lowest tone while the glass with the least water will have the highest.可知裝有最多的水的玻璃杯有最低的聲調(diào)，裝有最少的水的玻璃杯有最高的聲調(diào)。故選B。

【4】C

詞義猜測(cè)題。根據(jù)when you hit the glass, and this creates sound waves which travel through the water.可知敲玻璃杯時(shí)，產(chǎn)生的聲波，會(huì)導(dǎo)致玻璃杯震動(dòng)，故選C。

【5】C

推理判斷題。根據(jù)全文圍繞著一個(gè)實(shí)驗(yàn)，把裝有水的玻璃杯當(dāng)作樂(lè)器來(lái)進(jìn)行敲擊，產(chǎn)生不同的聲調(diào)，構(gòu)成音樂(lè)，這是在做科學(xué)實(shí)驗(yàn)，故推斷這篇文章摘自科學(xué)書(shū)籍。故選C。
