But like anything else wrth trying, a little planning and a lt f hard wrk will make yu appreciate it even mre when yu finally achieve it. Here are sme helpful steps and tips n hw t reach yur gal.
1. MAKE A GOAL
It's impssible t reach a gal if yu haven't set ne, s step ne f hw t reach yur weight－lss gal is, f curse, actually making ne! Hw much, realistically②， d yu want t lse, and, realistically, hw much time will it take? Write it dwn, and circle the date n yur calendar.
2．CLEAR THE KITCHEN
Yur next step is t clear yur kitchen f anything yu knw yu shuldn't be eating r drinking, especially the stuff yu find particularly tempting③. Fr me, I'd pen the cupbard and thrw away the crisps and then head t the fridge t get rid f the ice cream.
3．PLAN YOUR MENUS
Nw that all f the wicked④ temptatins⑤ are gne, it's time t plan what yu'll eat instead. Write a list f the things yu can and shuld eat every day. Make a plan fr five small meals, and make a list f everything yu'll need t make them, including tw snacks a day.
4．GO SHOPPING!
With that list in hand, head t the grcery stre! Stick t the uter edges f the stre, where all f the fresh prduce, healthy whle grains, and lean⑥ prteins are kept. Avid the inner aisles⑦ f junk fd, and head straight t the checkut.
5．JOIN THE GYM
All the dieting in the wrld wn't give yu the bdy r the imprved health yu want, if yu dn't pair it with a wrkut plan, and stick t it. It's time t jin the gym! Can't affrd steep membership fees? Then make yur wn wrkut at hme, by running each mrning, r ding aerbics. If yu can affrd it, hire a persnal trainer t help, t!
6．KEEP MOTIVATED TO KEEP GOING
It's been a few weeks since yu started yur weight lss jurney, and yu're ready t quit. It's hard t make all f these imprtant lifestyle changes all at nce, and it seems that temptatin is always lurking⑧ in the frm f birthday cakes and hliday celebratins. But hang in there! Remember what inspired yu t make all f these changes t begin with. Find yur inspiratin again, and use it t keep mtivated⑨ and keep ging!
[注释] ①daunting adj. 使人气馁的；吓人的

⑤temptatin n. 引诱；诱惑(物)

【译文】
减肥有时候是一个令人畏惧的过程，尤其是如果你不知道如何达成减肥目标，甚至不知道从哪开始时。但是就像其他值得尝试的事情一样，制订一个小小的计划并下一定的功夫，当你最终减肥成功时，你会倍加感激这一过程。以下是一些达成减肥目标的实用步骤和建议。
1．制定目标
没有树立目标，何谈实现目标。因此，达到减肥目标的第一步当然就是先制定一个目标。实事求是地讲，你想减多少重量？你想花多少时间减掉这些重量？把这些写下来，并在日历上圈出日期。
2．清理厨房
第二步是清理掉厨房里你认为自己不应该吃或喝的任何东西，尤其是对你来说极具诱惑力的食物。就我而言，我会打开橱柜，扔掉所有薯片，然后直奔冰箱，扔掉里面的冰激凌。
3.计划食谱
既然有害的诱惑物已经全部清除，现在是时候计划你要吃什么来代替那些食物了。把每天能够吃的和应该吃的东西列一个清单。计划每日五次便餐，并且列出制作这五餐所需要的所有食材，包括每日两次的小吃。
4．去购物！
拿着列好的清单，直奔杂货店。沿着商店的外围区域走，那里摆放着所有的新鲜农产品、健康的全谷类食品和精益蛋白质食物。不要去里面摆放垃圾食品的过道，然后直接去收银台结账。
5.去健身房
不是世界上所有的节食计划都能带给你想要的身材或健康，你需要将节食和锻炼结合起来，并且坚持下去。是时候去健身房锻炼了！支付不起高昂的会费？那你可以在家锻炼，比如每天晨跑或做有氧运动。如果你能够支付得起，还可以请私人教练帮助你减肥。
6．保持动力，继续前进
你已经有几个星期没有开始减肥了，你已经准备好戒烟了。很难一下子改变所有这些重要的生活方式，似乎诱惑总是以生日蛋糕和节日庆典的形式潜伏着。但是坚持住！记住是什么激励你从一开始就做出所有这些改变。再次找到你的灵感，继续前进！

[句式分析] 本句中不定式作目的状语。
(1)动词不定式(短语)作目的状语时，意为“为了……”；有时即使不直接译为“为了……”，但其中包含类似的意思，如“目的是”等。
❶T avid cnfusin with anther firm, the name was changed.
改名是为了避免和另一家公司(的名字)混淆。
❷Wrkers wrked thrugh the night t finish the prject as sn as pssible.
工人们彻夜工作，目的是尽快完成那个项目。
(2)动词不定式(短语)作目的状语时可放在句首、句中或句末。一般来说，用于句首属于强调性用法，即强调动作的目的。有时为了特别强调目的状语，可以在不定式之前加上in rder或s as，但s as不用于句首。
❸T illustrate my pint, I have dne a cmparative analysis.
为了说明我的观点，我作了对比分析。

2.(教材P45)It is nrmal fr teenagers t be slightly verweight and there is n reasn why they shuld be wrried.青少年轻微超重是正常的，他们没有理由担心。
[句式分析] 该句中的It为形式主语，句型为常用的高考重点句型。
It is/was＋adj.＋(fr/f sb.) t d sth.
该句型是It作形式主语的一个句型。如果不定式的逻辑主语是由fr引出的，句中的形容词通常是表示重要性、紧迫性、频繁程度、难易、安全等情况的形容词。常见的此类形容词有imprtant, necessary, natural, easy, safe, cmmn, nrmal, hard, difficult, dangerus, impssible, pleasant等。
❶It is impssible fr us t finish the wrk n time.我们不可能按时完成这项工作。
❷It is imprtant fr her t cme t the party.来参加这个聚会对她来说很重要。
如果不定式的逻辑主语是由f引出的，常用的形容词多为形容逻辑主语品质、特性的词，如clever, wise, bright, silly, flish, stupid, kind, cruel, right, wrng等。
❸It is kind f yu t help me.你能帮助我真是太好了。
特别提示：
it作为形式主语，既可代替不定式，也可代替从句，少数情况下可代替ding。
