10.As a recipe for losing weight,taking a slice of chocolate cake at breakfast would seem an unlikely fantasy.
A team from Tel Aviv University found that eating pudding as part of a balanced 600-calorie breakfast that also included proteins and carbohydrates (碳水化合物),could help dieter to lose more weight---and keep it off in the long run.
Attempting to avoid sweets entirely can create a psychological addiction to these same foods in the long term.So adding desserts to breakfast can control craving(渴望) throughout the rest of the day.
Over the course of a 32-week-long study,participants,who added desserts to their breakfast lost about 40pounds more than a group that avoided such foods.What's more,they kept off the pounds longer.
A meal in the morning provides energy for the day's tasks,aids in brain functioning,and kick-starts the body's metabolism (新陈代谢),making it decisive to weight loss and maintenance.And breakfast is the meal that most successfully regulates ghrelin(胃饥饿素),the hormone that increases longer.While the level of ghrelin rises before every meals,it is controlled most effectively at breakfast time.
The researchers hoped to determine whether meal time and composition had an influence on weight loss in the short and long term,or whether it was a simple matter of the caloric count.

28.According to the passage,the underlined word"it"in paragraph 2probably refers toD.
A.the calorie                        B.the breakfast
C.the craving for pudding            D.the lost weight
29.Adding some desserts in your breakfast diet properly willB.
A.make you gain more fat
B.make you become slim more easily
C.help improve your psychological health
D.help develop your craving for more delicious food
30.Through paragraph 5.the author wants to showC.
A.the special function of ghrelin
B.some decisive ways of losing weight
C.the great importance of breakfast to us
D.the nutrition we should take in during the breakfast
31.What will the passage develop next?A
A.Another experiment on weight loss.
B.An importance of calorie.
C.People's breakfast time.
D.The composition of the breakfast.

分析 本文属于说明文阅读,作者通过这篇文章主要向我们描述了早上吃一块甜品有可能变瘦,因为早餐能为人体提供能量,利于大脑运转,同时启动人体的新陈代谢机能.

30.C.考查段落大意.通读第5段可知"早餐能为人体提供能量,利于大脑运转,同时启动人体的新陈代谢机能,在减肥和维持身体机能方面有着重要意义…",可知本段讲了早餐的重要性.C项正确.
31.A.考查推理判断.根据最后一段中的"The researchers hoped to determine whether meal time and composition had an impact on weight loss in the short and long term,or whether it was a simple matter of the caloric count…",可知接下来会讲另外的实验.A项正确.
