答案解析：
36. focused
解析：be focused on是固定搭配，即使听不清-ed的音，根据语法知识，系动词之后如果是动词的某种形式的话，要么是-ed，要么是-ing，此处要补出词尾-ed。
37. Basically
解析：逗号之前一个独立的插入语往往是副词，注意不要漏掉al。
38. emotionally
解析：此处需要与前文的physically，mentally在形式上和语义上为并列关系的词。
39. distant
解析：此处需要形容词修饰future，"distant future"意思是“遥远的将来”。不远的将来表达为not-too-distant future或near future。
40. cancer
解析：不要误写为cancel。因为or的前面是heart disease，故此处应该填写另一种疾病。
41. retirement
解析：年轻的时候可能不会考虑生病、退休、死亡等，此词是retire的名词形式。
42. crossed
解析：根据语法知识，助动词have，has，had之后的动词要用过去分词形式，因此即使听不到-ed的音，也要补出词尾-ed。另外，不要误写成across。
43. increasingly
解析：此词修饰形容词或副词，表示“越来越”。
44. 标准答案：Regardless of your age, you can make a number of important changes in your current lifestyle
听音关键：Regardless，age，changes，current lifestyle
答案重构：No matter how old you are, you can make some great changes in your current lifestyle
画龙点睛：regardless of是四级常考短语；make changes为固定搭配；a number of后接名词复数形式。current lifestyle可能是难点，可以改写成present habits之类的表达。
45. 标准答案：We know much more about preventive health today than our parents and grandparents did in the past
听音关键：know more，preventive health，than，parents and grandparents
答案重构：We know preventive health much more now than our parents and grandparents did in the past
画龙点睛：注意比较结构和后半句的时态。preventive是个派生词，根据发音和上下文应该可以写对。
46. 标准答案：And this new knowledge can be transmitted to our children to help them become healthier than our generation
听音关键：knowledge，transmit，children，help，healthier，than our generation
答案重构：And this new knowledge can be passed on to our children so that they can be healthier than us
画龙点睛：knowledge是必须掌握的词汇，transmit可以替换，不定式目的可以用so that改写，our generation写成us意义上也没有什么遗失。
