1After bills, Tony has £60 a week to spend, £40 of which goes on food, but 10 years ago he was earning £130,000 a year working in corporate communications and eating at London's best restaurants at least twice a week.
主干主语：Tony；谓语：has；宾语：£60 a week to spend；后半：主语 he；谓语 was earning；宾语 £130,000 a year
结构前半为主句，After bills 作时间状语；£40 of which goes on food 为非限制性定语从句，which 指代 £60。but 连接并列分句，对比十年前：working... 与 eating... 为并列现在分词短语，作伴随状语修饰 was earning。
译文付完账单后，托尼每周只剩60英镑可花，其中40英镑花在吃上；可十年前他在企业传播行业年薪13万英镑，每周至少两次光顾伦敦最好的餐厅。
考点of which 引导非限制性定语从句，which 指代前面的金额 · 现在分词短语并列作伴随状语
2He's feeling positive, but he'll carry on blogging – not about eating as cheaply as you can – “there are so many people in a much worse state, with barely any money to spend on food” – but eating well on a budget.
主干主语：He；谓语：'s feeling；表语：positive；并列：he'll carry on blogging
结构but 连接并列句。破折号插入 not about... 与后文 but eating well... 构成 not...but... 结构，说明博客主题。引号内句子为插入解释，说明不愿写“极致省钱”的原因；with barely any money... 为独立主格/介词短语修饰 people。
译文他心态积极，但仍会继续写博客——不是写怎么吃得尽可能便宜——“还有很多人境况更糟，几乎没钱买吃的”——而是写如何在预算内吃得好。
考点破折号插入与 not A but B 对照 · 引语作插入解释，打断主句
3It's also a good idea to shop daily instead of weekly, because, being human, you'll sometimes change your mind about what you fancy.
主干形式主语：It；谓语：is；表语：a good idea；真正主语：to shop daily
结构It is a good idea to do 为形式主语结构。because 引导原因状语从句；being human 为现在分词作原因状语，插入在从句主语前。what you fancy 为介词 about 的宾语从句。
译文每天买菜而不是一周采购一次，也是个好主意，因为人嘛，有时会对想吃的东西改变主意。
考点形式主语 it + 不定式真正主语 · 分词 being human 插入原因从句
4Soon you'll feel comfortable asking if they've any knuckles of ham for soups and stews, or beef bones, chicken carcasses and fish heads for stock which, more often than not, they'll let you have for free.
主干主语：you；谓语：'ll feel；表语：comfortable；补足：asking...
结构feel comfortable doing 后接动名词。asking 的宾语为 if 引导的宾语从句。or 连接多种免费食材。which 引导定语从句修饰 stock（及前述骨头等），more often than not 为插入语；从句中 they'll let you have 为“让你免费拿走”。
译文很快你就会坦然开口问：有没有做汤炖菜用的火腿骨，或做高汤用的牛骨、鸡架、鱼头——十有八九他们会免费给你。
考点if 宾语从句作 asking 的内容 · which 定语从句 + 插入语 more often than not
5You won't be eating out a lot, but save your pennies and once every few months treat yourself to a set lunch at a good restaurant – £1.75 a week for three months gives you £21 – more than enough for a three-course lunch at Michelin-starred Arbutus.
主干主语：You；谓语：won't be eating out；并列祈使：save... and treat yourself
结构but 后为祈使句并列 save 与 treat。once every few months 作时间状语。破折号插入计算：£1.75 a week... gives you £21。more than enough... 为名词短语，补充说明 £21 的用途，for 引出目的。
译文你不会经常下馆子，但攒点零钱，每隔几个月犒劳自己一顿好餐厅的套餐午餐——每周1.75英镑，三个月就是21英镑——足够在米其林星级餐厅 Arbutus 吃一顿三道菜午餐。
考点祈使句与陈述句用 but 并列 · 破折号插入运算，后接名词短语补充说明
