Perhaps he would be able to earn his living after all and not have to close his restaurant. He did not look forward to beingin debt because his restaurant was no longer popular. He smiled as he weled some customers warmly at the door but the smile left his face when he saw Yong Hui walking in. She did not look happy but glared at him. “May I ask what you were doing in my restaurant the other day? I thought you were a new customer and now I know that you only came to spy onme and my menu,” she shouted. “Please excuse me,” he calmly explained, “I wanted to know where all my customers had gone last week. I followed one of them and found them in your restaurant. I dont want to upset you, but I found your menu so limited that I stopped worrying and started advertising the benefits of my food. Why dont you sit down and try a meal?”earn ones living谋生也可以说make a/ones living。after all意为“归根结底;毕竟;终究;仍然”。look forward to (doing) sth.期望/盼望(做)某事in debt欠债debt/det/n.债;债务no longernot .any longer不再(时间上)no morenot .any more不再(数量上)saw Yong Hui walking in 为see sb. doing sth.

When they were served the ice cream, Yong Hui began to look ill. “I feel sick with all this fat and heavy food,” she said, “I miss my vegetables and fruit.” Wang Peng was enjoying a second plate of dumplings so he sighed. “Yes,” he added, “and I would miss my dumplings and fatty pork. Dont you get tired quickly?”“Well, I do have to rest a lot,” admitted Yong Hui. “But dont you think it would be better if you were a bit thinner? Im sure youd feel much healthier.”enjoy dumplings品尝水饺;津津有味地吃水饺breast/brest/n.胸部;乳房breast of chicken鸡胸肉garlic/lIk/n大蒜过去分词短语cooked with garlic作定语,修饰breast of chicken。serve sb. sth.给某人端上食物a second plate of又一盘;再一盘a second不表示顺序,而表示数量、次数,意为“再一;又一”。sigh/saI/vi.叹息;叹气 n叹息;叹息声It would be better if .如果会更好一些(表示委婉地提出建议,句子用了虚拟语气)。第2段译文雍慧同意留下来,一会儿他们就津津有味地吃起水饺和蒜蓉鸡胸来。到吃冰淇淋时,雍慧开始感到不舒服了。她说:“吃了这么油腻的、难消化的食物,我都觉得恶心了。我想吃我的蔬菜和水果。”王鹏正在吃另一盘水饺,他叹了口气,说道:“同样,(如果在你的餐馆)我还想吃我的水饺和肥肉呢。你不觉得自己很容易疲倦吗?”“是的,我的确不得不需要经常地休息,”雍慧承认了,“不过,难道你不认为你瘦一点儿更好吗?我相信,那样你会觉得健康得多。”They began to talk about menus and balanced diets. “According to my research, neither your restaurant nor mine offers a balanced diet,” explained Wang Peng. “I dont offer enough fibre and you dont offer enough bodybuilding and energygiving food. Perhaps we ought to bine our ideas and provide a balanced menu with food full of energy and fibre.” So that is what they did. They served raw vegetables with the hamburgers and boiled the potatoes rather than fried them. They served fresh fruit with the ice cream. In this way they cut down the fat and increased the fibre in the meal. Their balanced diets became such a success that before long Wang Peng became slimmer and Yong Hui put on more weight. After some time the two found that their business cooperation had turned into a personal one. Finally they got married and lived happily ever after.according to根据neither .nor .既不也不,为并列连词,连接两个平行并列的成分。此处连接两个并列的主语,主谓一致采用“就近一致”原则。bine/kmbaIn/vt.&vi.(使)联合;(使)结合bine A with Bbine A and B把A和B结合/联合起来with复合结构(withn.adj.),作定语,修饰a balanced menu。what引导的表语从句,what在表语从句中作did的宾语。rather than意为“而不是”,连接并列成分。in this wayby this means/with this method用这种办法cut down削减;删节a success中的success为可数名词,此处意为“成功的事”。before long不久以后put on weight增加体重(gain weight)cooperation/kpreIn/n合作;协作cooperate v合作;协作turn into成为;变成第3段译文他们开始谈论菜谱和均衡膳食的问题。王鹏解释道:“根据我的研究,你我两家的餐馆所提供的都不是均衡的膳食。我没有提供足够的膳食纤维,而你提供的食物没有足够的营养和热量。也许我们应该把我们的想法结合起来,提供一份富含热量和纤维的均衡食谱。”于是,他们就照此做了。他们用生蔬菜配汉堡包,煮土豆而不是油炸土豆,还拿新鲜的水果配上冰淇淋。这样,他们减少了饭菜中脂肪的含量,增加了纤维素。他们的均衡膳食非常有效,王鹏不久之后就瘦了,而雍慧也增加了些体重。过了不久,这两个人发现,他们生意上的合作变成了私人的合作了。最后,他们结了婚,从此过上了幸福美满的生活。Step 1True (T) or False (F)1Yong Hui came to Wang Pengs restaurant in order to spy on him.()2Yong Hui stayed in Wang Pengs restaurant and enjoyed dumplings and breast of chicken.()3Wang Peng and Yong Hui quarrelled in the end.()答案:1.F2.T3.FStep 2Read the text and choose the best answers.1Wang Peng was worried when he thought _.Ahe would be in debtBhe could no longer earn his livingChe would lose his job Dhis friends would not visit him2Yong Hui was very angry when she came to Wang Pengs restaurant because _.Ashe thought he was a new customer Bshe thought he had spied on her restaurantCshe was told he was a spyDhe was too fat3Wang Pengs research showed _.Ahis menu was balancedBboth menus were balancedCYong Huis menu was balancedDneither menu was balanced4He suggested they provide a bined menu because _.
