1．Something terrible must have happened if Li Chang was not coming to eat in his restaurant as he always did.

[句式分析]　此句为复合句。if引导条件状语从句；as 引导方式状语从句；must have done"一定已经做了......"，是对过去发生的事情的肯定推测。

[自主翻译]　要是李昌不像往常一样到他的饭馆吃饭，那么一定是发生了什么严重的事情。

2．At the library Wang Peng was surprised to find that his restaurant served far too much fat and Yong Hui's far too little.

[句式分析]　此句为复合句。that引导的是宾语从句，作find的宾语；Yong Hui's far too little在Yong Hui's后面省略了served。

[自主翻译]　在图书馆，王鹏惊奇地发现：他的餐馆提供的食物脂肪含量高，而雍慧的餐馆提供的食物脂肪含量低。

3．Even though her customers might get thin after eating Yong Hui's food，they were not eating enough energy­giving food to keep them fit.

[句式分析]　此句为复合句。even though引导让步状语从句；to keep them fit为不定式短语作目的状语；keep them fit是"keep＋宾语＋宾补"结构，宾补由形容词充当。

[自主翻译]　即使雍慧的顾客吃了她的食物会变瘦，但是他们吃不到提供足够能量的食物来使他们保持健康。

Ⅰ.阅读理解

　　Have you wondered about the amount of time we spend talking about food and been surprised？We are always asking questions such as "Have you ever eaten？" and "What did you have for lunch？" Yet，if you travel from one country to another，you might find that other nations think differently about food.People plan to think that what they eat is normal and what everyone else eats is strange.In most parts of Asia，for example，no meal is complete without rice but in England，rice is the exception and people prefer to eat potatoes.In the Middle East，bread accompanies every meal.

Eating，like so many things we do，becomes a habit that is difficult to change.The Americans seem to like drinking lots of orange juice and coffee；the English prefer to drink tea four or five times a day；the Australians prefer to drink a lot of beer；the French like wine every day.
