课时作业(十九)　Unit 3　Fit for life 一、阅读理解 (2022· 江苏省泰州市第四次调研)A blood test that accurately predicts a patient’s likelihood of dying from heart disease or a stroke(中风) has been developed. Researchers took samples of blood from 22，949 people and analyzed the levels of about 5，000 proteins within it. They then used machine learning to detect whether there was a link between the proteins that circulate in a person’s bloodstream and their risk of heart disease. The study identified a particular “protein signature” that accurately predicts the chance of suffering a heart attack, stroke or heart failure over a four­year period. Currently, doctors assess the likelihood of patients suffering heart problems by looking at factors including weight, blood pressure, age and cholesterol(胆固醇) levels. However, blood protein analysis can provide more accurate clues to the state of a person’s health. The technology was found to be twice as accurate as existing tools at measuring a patient’s heart risk. The blood test could also provide a faster way of detecting whether patients’ existing medication(药物治疗) is working and helping to reduce their risk. Existing risk assessments struggle to do this. The blood test was developed by SomaLogic, based in Boulder, Colorado. The company is also working with scientists at Imperial College London to help develop a blood test to detect cancer. Professor Elio Riboli said this could lead to widespread screening for many different types of cancers, which is not possible using existing techniques. His team will work with SomaLogic to analyze 15，000 blood samples from people who had developed cancer, comparing them with 10，000 samples from people who did not. The results will be used to establish whether there are protein markers that could indicate if someone is at risk from the disease. In 2019, a trial began in Leeds to use SomaLogic’s technology to assess people’s risk of diabetes, and also the effectiveness of lifestyle changes in preventing the condit
