【墨尔本PTE】【 PTE真题】PTE听力和口语一直是PTE口语考试中最重要的部分,今天墨尔本文波PTE培训学校给大家总结下PTE中的RL真题:


So this is one picture that probably you all know what it is when you see it. It is a familar looking image, it’s something that probably we all have some personal experience with it. Right, this is a chest X-ray that will be taken in your doctor’s office for example, or radiologist office. And it is a good example of biochemical engineering and that it takes a physical principle that is how do X-rays interact with the tissues of your body and it uses that physics, that physical principle to develop a picture of what’s inside your body. So to look inside to see the things you couldn’t see without this device. and you recognise some of the parts of the image you can see the rib cage, here are the bones, you can see the heart is this large bright object down here. If you have good eyesight from the distance, you can see the vessels leading out of the heart into the lungs and lungs are these darker spaces within the rib cage.
