정답 ④

해설 이 글은 신체가 운동 중 산소 공급 여부에 따라 에너지 생성 방식(무산소에서 유산소로)을 어떻게 전환하는지 설명하고 있으므로 'How Energy Systems Change During Your Workout'이 정답이다.

Q7 어법1 다음 글의 밑줄 친 부분 중, 어법상 틀린 것은?

To understand how breathing affects athletic performance, we first need to understand how the body makes energy from air and food. There are two options: with oxygen, a process ① known as aerobic respiration, and without it, which is called anaerobic respiration. Anaerobic energy ② is generated only with glucose (a simple sugar), and it's quicker and easier for our bodies to access. It's a kind of backup system and turbo boost when the body doesn't have enough oxygen. But anaerobic energy is inefficient and can be toxic, creating too much lactic acid. The sickness, muscle weakness, and sweating you experience after you've pushed it too hard at the gym is the feeling of anaerobic overload. This process explains ③ because the first few minutes of an intense workout are often so miserable. Our lungs and respiratory system haven't caught up ④ to supply the oxygen our bodies need, and so the body has to use anaerobic respiration. This also explains why, after we're warmed up, exercise feels easier. The body ⑤ has switched from anaerobic to aerobic respiration.

To understand how breathing affects athletic performance, we first need to understand how the body makes energy from air and food. There are two options: with oxygen, a process known as aerobic respiration, and without it, which is called anaerobic respiration. Anaerobic energy is generated only with glucose (a simple sugar), and it's quicker and easier for our bodies to access. It's a kind of backup system and turbo boost when the body doesn't have enough oxygen.

(A) But anaerobic energy is inefficient and can be toxic, creating too much lactic acid.

(B) The sickness, muscle weakness, and sweating you experience after you've pushed it too hard at the gym is the feeling of anaerobic overload. This process explains why the first few minutes of an intense workout are often so miserable. Our lungs and respiratory system haven't caught up to supply the oxygen our bodies need, and so the body has to use anaerobic respiration.

(C) This also explains why, after we're warmed up, exercise feels easier. The body has switched from anaerobic to aerobic respiration.

• ① (A) - (B) - (C)
• ② (A) - (C) - (B)
• ③ (B) - (C) - (A)
• ④ (C) - (A) - (B)
• ⑤ (C) - (B) - (A)

정답 ①

Q16 요약문빈칸 다음 글을 아래와 같이 요약하고자 한다. 빈칸에 들어갈 알맞은 어휘를 주어진 철자로 시작하여 각 한 단어로 답안을 작성하시오.

Athletic performance relies on two distinct energy production methods: (a)a____________ and (b)a____________ (c)r____________. While anaerobic respiration provides a rapid energy boost during intense exercise, it is inefficient and leads to the accumulation of toxic lactic acid. Conversely, aerobic respiration becomes the primary energy source once the respiratory system adapts to the physical demand. Understanding this transition explains why initial exercise feels difficult before the body successfully shifts to a more sustainable and (d)e____________ oxygen-based process.

정답
(a) aerobic [에어로빅; 유산소의] - Athletic performance relies on two distinct energy production methods: aerobic and anaerobic respiration.
(b) anaerobic [혐기성의; 산소 없이 작용하는] - Athletic performance relies on two distinct energy production methods: aerobic and anaerobic respiration.
(c) respiration [호흡] - Athletic performance relies on two distinct energy production methods: aerobic and anaerobic respiration.
(d) efficient [효과적인] - Understanding this transition explains why initial exercise feels difficult before the body successfully shifts to a more sustainable and efficient oxygen-based process.
