본문� 1

Have you ever wondered what makes a kite fly, or what a kite and an

airplane have in common? The truth is that they both rely on the same

science — the science of flight.

무엇이 연을 날게 하는지, 또는 연과 비행기가 어떤 공통점을 갖고 있는지 궁금해한 적이 있는가? 진실은 그 둘

모두에게 비행의 과학이라는 똑같은 과학이 적용된다는 것이다.

Basics of Flight

There are four main forces involved in flight: lift, weight, thrust, and drag. Lift

is created by the difference in air pressure between the air flowing over an

airplane's wings and the air flowing under them.

비행의 기본 원리

비행과 관련 있는 4가지 주된 힘, 즉 양력, 중력, 추력, 항력이 있다. 양력(lift)은 비행기 날개 위로 흐르는 공기와 날개 아

래로 흐르는 공기 간의 압력 차이로 만들어진다.

Lift is opposed by weight, which is the force of gravity that is constantly

pulling the airplane down. If the amount of lift is greater than the amount of

weight, the airplane will rise.

양력은 중력(weight)에 반대되는 힘인데, 중력은 지속적으로 비행기를 아래로 끌어당기는 힘이다. 양력의 양이 중

력(weight)의 양보다 더 크면 비행기는 떠오를 것이다.

At the same time, thrust is created by the airplane's engines and propellers

pushing the airplane forward. Opposed to that force is drag, which is the air

pushing the airplane back. If thrust is greater than drag, the airplane will

move forward. The interaction between these four forces makes airplanes fly.

동시에, 추력(thrust)은 비행기의 엔진과 프로펠러에 의해 만들어지는데 비행기를 앞으로 밀어 준다. 그 힘의 반대

는 항력(drag)인데, 이는 비행기를 뒤쪽으로 밀어 주는 공기이다. 만약 추력이 항력보다 더 크면 비행기는 앞으로

움직일 것이다. 이 네 가지 힘이 상호 작용하면서 비행기를 날게 한다.

중요 변형문제 ★★★ 출제율 1위 유형 - ‘ 일치.불일치 ’ ★★★


Airplanes are designed with these forces in mind. The engines and propellers provide

thrust to move airplanes forward. The wings are shaped so that air has to travel

faster over them than under them. According to Bernoulli's principle, an increase in

the speed of air results in a decrease in pressure. Thus, air traveling faster creates

lower pressure above the wings, and the higher pressure under the wings pushes the

airplane up, creating lift.

① The source of thrust of airplanes is engines and propellers.

② The faster the speed of air is, the higher pressure becomes.

③ Pressure over wings is lower than pressure under them in flight.

④ Bernoulli's principle explains how the speed of air is related with pressure.

⑤ Bernoulli's principle is applied to the design of airplanes.

You can see for yourself how the force of lift works. Cut a strip of paper

about 4 cm wide. Hold one end of the strip near your lips, and blow slowly

and evenly over the paper. The other end of the strip will rise. This is

because the air blown out over the top of the paper moves quickly, so its

pressure is lower than the still air under the paper. The still air, with a higher

pressure, pushes the paper upward into the lower pressure air.

① it decreases the speed of the air

② it makes the air go faster than the air under it

③ it makes the same amount of pressure as under it

④ it removes substances to disturb the experiment

⑤ it makes bigger pressure than the pressure under it


① The experiment is carried out to see the principle of lift.

② The item we need is a strip of paper around 4 cm wide.

③ Over the paper, the speed of the air is higher and the pressure is lower.

④ If you blow over the paper from one end, the other end will rise because

of difference in pressure.

⑤ Affected by the wind blown out, the air moves a little under the paper,

thus pushing the paper upward.

본문� 3

Why a Kite Flies

A kite flies in the same way as an airplane does. To make a kite fly, it is

sometimes necessary to run with it behind you. This creates lift and pushes

the kite up.

연이 나는 이유

연은 비행기와 똑같은 방식으로 난다. 연을 날게 하기 위해서는 때로는 여러분의 뒤쪽에 연을 둔 채로 뛰어야 한

다. 이것은 양력을 만들어 내고 연을 위로 밀어 준다.

Once the kite gets up in the sky where the wind is strong enough, you can

stop running, and the kite will fly. Instead of engines and propellers, the

tension from someone pulling on the kite's string provides thrust for a kite.

일단 연이 바람이 충분히 강한 하늘 위로 올라가게 되면, 여러분은 달리기를 멈출 수 있고 연은 떠 있게 될 것이

다. 엔진과 프로펠러 대신에, 연줄을 당기는 장력이 연에 추력을 제공한다.

For a kite to remain flying, the amount of lift needs to be equal to the

amount of weight so that those forces balance each other. Likewise, thrust

and drag must also be equivalent.

연이 날고 있는 상태를 그대로 유지하려면, 힘들이 서로 균형을 잡을 수 있도록 양력과 중력의 양이 같아야 한다.

이와 마찬가지로, 추력과 항력도 동등해야 한다.

Bangpaeyeon, the most popular Korean kite, looks simple, but is the toughest

of all kites flown in Korea. This rectangular kite is traditionally made from five

bamboo sticks and is covered with traditional Korean paper. bottles to each

본문 4

연의 정면에 있는 공기가 미는 힘은 바람의 일부가 구멍을 통해 빠져나감으로써 크게

감소하고, 이는 연을 빠르게 돌릴 수 있게 해준다. 또한 강한 바람에도 쉽게 망가지지

않는다.

연의 예에서 알 수 있듯이 우리 일상생활에는 많은 흥미로운 과학 원리들이 있다.

꼬리도 연이 더 안정적으로 날 수 있게 도와준다. 허나 그 길이도 적당해야 한다. 우리

선조들은 이 모든 것을 알아 적당한 길이의 꼬리를 사용했다.


본문� 4

The push of air on the front of the kite is greatly reduced because some of

the wind passes through the hole to the back. This allows you to turn the

kite quickly.

연의 정면에 있는 공기가 미는 힘은 바람의 일부가 이 구멍을 통해 뒤로 빠져 나가기 때문에 크게 감소한다. 이것

은 여러분이 연을 재빠르게 돌릴 수 있게 해 준다.

Without the hole, it would not be easy to control. In addition, the kite is not

easily damaged by a strong wind.

구멍이 없다면, 통제하기 쉽지 않을 것이다. 게다가, 이 연은 강한 바람에 쉽게 망가지지 않는다.

As you can see from the example of the kite, things we use every day often

act in accordance with interesting principles of science. Make sure you think

about these principles at work in your daily life.

연의 예를 통해 알 수 있듯이, 우리가 일상생활에서 사용하는 것들이 흔히 흥미로운 과학 원리에 따라 작용한다.

일상생활에서 작용하고 있는 이런 원리에 대해 꼭 생각해 보자.

A Way to Increase Stability: A Tail

A tail is sometimes added to a kite. It can help make a kite fly more stably

by adding not just some weight but also drag to its lower end.

안정감을 증가시키는 방법: 꼬리

때때로 연에는 꼬리가 달리기도 한다. 이는 연의 하단부에 중력뿐만 아니라 항력을 더해 줌으로써 연이 좀 더 안정

적으로 날 수 있게 도와준다.

The tail should have the right length, though. Adding a short tail, for

example, a 10 cm tail, will make the kite spin and roll around a lot.

그러나 꼬리의 길이는 적당해야 한다. 예를 들어, 10센티미터 정도의 짧은 꼬리를 달게 되면 연은 제자리에서 돌거

나 심하게 흔들릴 것이다.

Adding a longer tail, such as a 100 cm tail, can help the kite fly well,

allowing it to go high without rolling very much. Our ancestors knew all this

and made the tail the right length.

100센티미터 정도의 긴 꼬리는 연이 잘 날게 도와주어, 많이 흔들리지 않고 높이 올라갈 수 있게 해 줄 것이다.

우리 선조들은 이 모든 것을 알았고, 꼬리를 적당한 길이로 만들었다.

without rolling very much. Our ancestors knew all this and made the tail the

⦁Every kite has its tail to stay stable.

⦁The right length of tails depends on kind of kite.

⦁Weight and drag prevent kites from shaking in the air.

⦁A 100 cm tail is more effective than a 10cm tail in making kites fly well.

⦁Not until recently has the importance of the right length of tails found.

① 1개 ② 2개 ③ 3개 ④ 4개 ⑤ 5개


① Too short tails will cause kites to spin and roll so much.

② Not all tails are suitable to a kite because its stability depends on their

weight.

③ A tail is put in order that the kite can keep steady.

④ For a kite to remain flying stably, both weight and drag are required.

⑤ Our ancestors were aware of the relationship between kites and their tails.

Bangpaeyeon, the most popular Korean kite, looks simple, but is the toughest of

all kites flown in Korea. This rectangular kite is traditionally made from five

bamboo sticks and is covered with traditional Korean paper. It is always made so

that the width and length are in a 2-by-3 proportion. Unlike kites in other

countries, it has a circular hole in the center, with a diameter half the width of the

kite. What this hole does is control the air. The push of air on the front of the

kite is greatly reduced because some of the wind passes through the hole to the

back. This allows you to turn the kite quickly. Without the hole, it would not be

easy to control. In addition, the kite is not easily damaged by a strong wind.

① Bangpaeyeon’s length is longer than its width.

② In contrast to its simple appearance, bangpaeyeon is difficult to fly.

③ Thanks to the hole, the amount of the air the kite faces increases.

④ Kites in other countries except for bangpaeyeon rarely have a circular hole

in the center.

⑤ The diameter of the hole bangpaeyeon has in the center is half of the

width of it.

새는 전깃줄에 앉아도 감전되지 않는다. 이는 새가 같은 전압의 선 위에 올라가 있기

보충지문

Why can a bird stand on a power line and not get shocked? This has to do

with how electricity works. Electricity flows between two points that differ in

voltage. to his studio and stopped to listen to a street musician.

새는 왜 전깃줄에 앉아 있어도 감전되지 않을까? 이것은 전기는 어떻게 작용하는가와 관련이 있다. 전기는 전압이

다른 두 지점 사이를 흐른다.

Since there is no voltage difference between the bird's feet, electricity does

not flow through the bird's body. If a bird touches two wires that differ in

voltage, however, electricity will flow through the bird and will probably give it

an electric shock.

새의 발 사이에 전압이 다르지 않기 때문에 새의 몸으로 전기가 흐르지 않는다. 그러나 만약 새가 전압이 다른 두
