Scripts 163 M: Exactly. Scientists say that telomere length can be a predictor of disease risk and even early death. Telomere shortness has been linked to chronic conditions such as diabetes, cardiovascular diseases, lung diseases, and certain cancers. W: Wow! That’s very interesting. Viewing & Doing B. Watch an Example Video p. 60 M: Hello, I’m David Brown from the National Science Foundation, and I’m going to introduce a newly developed product. ( Showing a wing-suit ) Have you heard of a wing-suit? It is an article of clothing that allows people to glide through the air. It’s quite different from the flying vehicles you are familiar with, like airplanes or helicopters, isn’t it? ( Showing a sugar glider ) This cute creature is called a sugar glider. Its name comes from the fact that it loves sweet food such as sugar and honey, and because it can glide from tree to tree. We invented clothing imitating the ability of this cute animal. We invented the wing-suit based on this ability. The sugar glider glides by means of a “patagium”―a thin membrane of skin covered with fur. This gliding membrane stretches from its hands to its ankles. When flying, the animal is able to control and change the size and shape of the membrane by changing the position of its limbs. Meanwhile, its tail also helps it manage the flight. The sugar glider is able to glide up to 45 meters at a time. When finishing a glide, it uses its sharp nails to cling onto nearby branches. After several years of research and observation, we were finally able to invent this wing-suit. I hope this video helps you understand our invention in detail. Thanks for watching. Bye. Do It Yourself A p. 62 M: I’m not feeling myself lately. I keep forgetting things. W: That sounds serious. Have you talked to your doctor about it? M: I will. I have an appointment next week. W: ‌That’s good. Memory loss can be a sign of dementia, but there are also many other possible causes. Have you experienced any other symptoms? M: ‌I have trouble keeping track of time and sometimes get confused about where I am. W: ‌It’s important to keep track of any changes in your cognitive abilities. Early detection and treatment can be crucial for managing dementia. M: ‌That’s very good advice. Thank you for being so helpful. W: ‌Of course. It’s important to take care of ourselves and each other. B W: Have you heard of metamorphosis, the process through which moths and butterflies develop? It comes from a Greek word meaning “transformation” or “a change in shape.” There are four stages in the metamorphosis of butterflies: egg, larva, pupa, and adult. First, eggs are laid on plants by an adult female butterfly. These plants will then become the food for the hatching caterpillars. The next stage is the larva. This is also called a caterpillar. The job of the caterpillar is to eat and eat and eat. As the caterpillar grows, it splits and sheds its skin and sheds the skin about 4 or 5 times. The food it eats at this time is stored and used later when it becomes an adult. When the caterpillar is fully grown and stops eating, it becomes a pupa. The last stage is what most people think of when they think of butterflies. It looks very different from the larva. The adult has long legs and compound eyes. It can also fly by using its large and colorful wings.
