解析:第一空考查with的用法。表示“通过,使用”;第二空为固定短语,win back意为“赢回”。
 
4.Their balanced diets became such a success__that__before long Wang Peng became slimmer and Yong Hui put__on__more weight.

7.But don't you think it would be better if you were a bit__thinner__(thin).
 
解析:考查形容词的比较级,a bit修饰比较级。
 
8.I found your menu so__limited__(limit) that I stopped__worrying__(worry) and started advertising the benefits of my food.
 
解析:第一空考查词形转换“find+宾语+adj.”,limited“有限的”;第二空考查“stop doing sth.”。
 
9.According__to__my research, neither your restaurant nor mine__offers__(offer) a balanced diet.
 
解析:第一空考查according to意为“根据”;第二空考查主谓一致,谓语动词就近原则。
 
10.They were both enjoying dumplings and breast of chicken__cooked__(cook) with garlic.
 
解析:考查非谓语动词作定语。cook与chicken之间为被动关系,故用cooked。
 
Ⅴ. 语篇填空
