Watch the video once and answer the following questions.
How difficult was this video for you and why? How many new words and phrases do you feel it has? How was the speed? Too fast, too slow? Discuss with the teacher.
Next read through the paragraphs below.
例え上級レベルの生徒さんであったとしても、しばしば “s”をを付けることや複数形を使うことを忘れてしまったり、聞き逃してしまうことがあります。 では、もう一度ビデオを観ながら以下の4つのパラグラフの”s”に耳を傾けてみましょう。
All of the s’s have been removed. Even high-level students often forget to add s or use the plural form. Try to replace all of the missing s’s in the first 4 paragraphs only. Watch the video again and try to listen for the s’s
“The heart pump blood throughout the body. Carrying oxygen and nutrient to every cell. It’s this circulation of blood that is vital to sustaining life.
The heart is an organ made up of several tough layer of muscle. The pericardium is the thin layer that cover the exterior while the endocardium line the inside wall. The heart is divided into four chamber. Two upper and two lower. The upper chamber known as the atrium receive blood coming into the heart. The lower chamber are the ventricle that pump blood out.
Between each chamber are valve that open and close and help keep the blood moving.
They are the tricuspid, mitral, pulmonary, and aortic valve. A pumping cycle start when oxygen depleted blood return to the heart after circulating throughout the body. The blood enter through the right atrium before flowing to the right ventricle. It’s then pumped to the lung via the pulmonary arteries. There blood is rejuvenated by air that breathed in. The oxygen rich blood return to the heart through the left atrium where it go to the left ventricle. Then by way of the aorta artery the fresh blood is pumped throughout the body before the process repeat itself.
That process happens with every heartbeat. And it’s relentless. The heart beats 100,000 times a day. 40 million times a year and up to three billion times over an average lifespan. But there are conditions that can disrupt a heartbeat and that normality. They can range from myocardial infarction or heart attack to heart disease and hypertension. In contrast, exercise and emotional excitement can also have an impact on a person’s heartbeat. The various blood vessels that comprise the circulatory system are a network of veins, arteries, and capillaries that span over 60,000 miles throughout the body. And the heart is the pump at the center of it.
The heart pumps blood throughout the body. Carrying oxygen and nutrients to every cell. It’s this circulation of blood that is vital to sustaining life.”
