Adapted from The New York Times 2024.10.30 Autumn is in full swing， which means supermarket produce sections are ripe with the finest late-season fruits and vegetables and often pricier organic versions of each. If buying organic isn't in your budget this fall， experts say not to worry， as you're likely to get the same nutritional benefits from conventional foods. 返回导航 13 Then， why are organic foods more expensive? One reason is that the Department of Agriculture sets strict guidelines for organic food producers. Certified organic produce， for instance， must be grown without the use of most synthetic pesticides（杀虫剂） and herbicides（除草剂）. And animal products such as meat， poultry， dairy and eggs must come from animals given year-round access to the outdoors and raised without growth antibiotics. Organic products can't use genetic engineering， either. 返回导航 Therefore， producing them requires more labor， said Sean Svette， a director of the nutrition and dietetics program at the University of Colorado Colorado Springs. An organic farmer who doesn't use a powerful weed-killing herbicide， for instance， may need to hire more workers to remove the weeds. But do higher costs mean more nutrients? With macronutrients like protein， carbohydrates （碳水化合物） and fat， there are no 返回导航 differences between organic and nonorganic foods， said Lizzy Davis， an assistant professor of nutrition sciences at the University of Alabama at Birmingham. Some studies do suggest small differences between micronutrients like vitamins， minerals and certain antioxidants. One study found， for instance， that organic marionberries and corn might contain higher antioxidant levels than their nonorganic counterparts. But these findings have been inconsistent. 返回导航 And researchers haven't proven that these micronutrient differences are big enough to affect health， she added. Therefore， if you can't afford to buy everything organic， Mr. Svette recommended focusing on the foods you eat the most. Ultimately， experts say that the best thing you can do for your health is to prioritize nutritious foods in general， like fruits， vegetables， whole grains and unprocessed foods， whether they're organic or not. 返回导航 1.organic adj.有机的 2.autumn is in full swing 秋声正盛 3.ripe adj.成熟的 4.pricy adj.价格高的，昂贵的 5.in one's budget 在某人的预算内 6.conventional adj.常规的 返回导航 18 7.guideline n.指导方针 8.certified adj.经认证的；合格的 9.synthetic adj.合成的 10.poultry n.家禽 11.access n.机会 12.antibiotic n.抗生素 13.genetic engineering 基因工程 14.labor n.劳力 返回导航 19 15.hire v.雇用 16.macronutrient n.宏量营养素 17.antioxidant n.抗氧化剂 18.contain v.包含 19.counterpart n.同类产品 20.prioritize v.优先考虑 返回导航 20 similar nutritional value conventional foods and organic foods 返回导航 21 Organic ones are pricier due to 1._________________________ and higher labor.

At last， Beth touched the instrument （乐器）， beginning to play. She stayed till Hannah came to take her home to dinner， but she had no appetite<m></m>， and could only sit and smile upon everyone. 返回导航 28 After that， the little girl went to the great house nearly<m></m> every day. She never knew that Mr. Laurence often opened his door to hear the old music he liked. She never saw Laurie standing in the hall to keep the servants away. And she never suspected<m></m> that the music which<m></m> she found on the piano was put there for her， and when Mr. Laurence talked to her about music at home， she 返回导航 only thought how<m></m> kind he was to tell things that<m></m> helped her so much. “Mother， I'm going to make Mr. Laurence a pair of slippers. He is so kind to me. I must thank him， and I don't know any other way. Can I do it?” asked Beth， a few weeks after his visit. 返回导航 “Yes， dear. It will please him very much， and be a nice way of thanking him. The girls will help you， and I will pay for the material<m></m>，”replied Mrs. March happily. Beth worked early and late on the slippers for quite some time， so they were soon finished， and she wrote a short， simple note， and with Laurie's help， got them onto Mr. Laurence's desk one morning before he was up. 返回导航 31 Beth waited all day and part of the next before a response<m></m> came from the old man. The next afternoon， however， when she returned from a walk around the neighborhood<m></m>， she found a letter and a little piano waiting for her. “For me?”cried Beth. 返回导航 32 “Yes， all for you， my precious<m></m>! Isn't it splendid （极好的） of him? Don't you think he's the dearest old man in the world? We didn't open the letter， but we are dying to<m></m> know what he says，” cried Jo， hugging<m></m> her sister. “You read it! I can't! Oh， it is too lovely!” 返回导航 33 Miss March: Dear Madam， I have had many pairs of slippers in my life， but I never had any that suited<m></m> me so well as yours<m></m>.I hope you will allow<m></m> me to send you something that once belonged to<m></m> the little granddaughter I once had. I am grateful for your friendship and wish you the best. Sincerely， James Laurence 返回导航 34 “Oh， Beth， now that's an honor<m></m> to be proud of. I'm sure! Laurie told me how fond<m></m> Mr. Laurence used to be of the child who died， and how he kept all her little things carefully. He's given you her piano. You'll have to go and thank him，” said Jo， jokingly （开玩笑地）. “Yes， I guess I'll go now before I get frightened<m></m> thinking about it.”And to the amazement of the family<m></m>， Beth walked to the Laurences' door. 返回导航 35 They would have been still more amazed if they had seen<m></m> what Beth did afterward. She went and knocked at the study door， and when he called out， “Come in!” she did go<m></m> in， right up to Mr. Laurence， and held out her hand<m></m>， saying， “I came to thank you， sir.” But she didn't finish， for<m></m> he looked so friendly that<m></m> she forgot her speech and， only remembering that he had lost the little girl he loved， she put both arms round his neck and kissed him. 返回导航 The old gentleman was astonished<m></m>， but he liked it! He then set her on his knee as<m></m> he had done with his granddaughter. Beth no longer feared him from that moment， and sat there talking to him as comfortably as if<m></m> she had known him all her life. When she went home， he walked with her to her gate， then shook hands<m></m> gently<m></m>. 返回导航 ①appetite n.胃口 ②nearly adv.几乎 ③suspect v.怀疑 ④此处为which引导定语从句，which在从句中作宾语。 ⑤此处为how引导宾语从句，how在从句中表示程度。 ⑥此处为that引导定语从句，that在从句中作主语。 ⑦material n.材料 ⑧response n.回应 返回导航 38 ⑨neighborhood n.街区 ⑩precious ［熟词生义］ n.宝贝 ⑪be dying to渴望 ⑫hug v.拥抱 ⑬suit v.适合 ⑭yours为名词性物主代词，代指贝丝为劳伦斯先生做的鞋子。 ⑮allow v.允许 ⑯belong to属于 返回导航 39 ⑰honor n.荣幸 ⑱fond adj.喜爱的 ⑲frightened adj.害怕的 ⑳to the amazement of the family让全家人吃惊的是 ㉑此处为if条件状语从句的虚拟语气，表示对过去的虚拟。 ㉒此处为对谓语动词的强调。 ㉓hold out one's hand伸出手 ㉔for在此处表示原因。 返回导航 40 ㉕“so...that...”意为“如此……以至于……”。 ㉖astonished adj.吃惊的 ㉗as意为“正如”，引导方式状语从句。 ㉘as if好像 ㉙shake hands握手 ㉚gently adv.温柔地 返回导航 41 $
