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.

13.Hundreds of years ago,a Roman army came north from England to make war on Scotland.The Scots,a brave people,loved their country very much.They fought hard to drive the enemy out of Scotland,but there were too many Romans.It looked as if the Romans would win.
  One night,the leader of Scots marched his soldiers to the top of a hill."We will rest here tonight,my men,"he said."Tomorrow we will fight one more battle.We must win or we will die."
  They were all very tired,so they ate their supper quickly and fell asleep.There were four guards on duty,but they,too,were very tired,and one by one,also fell asleep.
  The Romans were not asleep.Quickly they gathered at the foot of the hill.Slowly they climbed up the hillside,taking care not to make a sound.Closer and closer they came to the sleeping Scots.They were almost at the top.A few minutes more,the war would be over.Suddenly,one of them put his foot on a thistle(蓟).He cried out and his sudden cry woke the Scots.In a moment,they were on their feet and ready for battle.The fighting was hard but it did not last long.The Scots wiped out the Romans and saved their country.
  The thistle is not a beautiful plant.It has sharp needles all over it.Few people like it.But the people of Scotland liked it so much that they made it their national flower.
