44. 标准答案：At my annual checkup, the doctor asked how much I drank
听音关键：annual, checkup, drank
答案重构：At my yearly checkup, the doctor asked how much I drank
画龙点睛：因为上下文都是过去时，所以注意本句的动词要用过去式（“asked”和“drank”），同时还要注意句首大写。
45. 标准答案：At the moment, I became one of the five percent of alcoholics who can simply quit drinking

画龙点睛：注意alcoholics的拼写，如果实在不能保证正确，可以用drinkers代替，但是都需要用复数形式。quit要加doing sth.，所以要用drinking，而不是drink。
46. 标准答案：Like my doctor's expression, it stayed with me and helped me stay sober
听音关键：expression, stayed, sober
答案重构：It, like my doctor's expression, stayed with me and helped me keep away from alcohol
