15.Many parents worry that their children's eating habits may not be good enough to stay healthy.Some children ask for the same food over and over again,some may refuse to try anything new,and some may keep asking for snacks (点心).Therefore,having healthy eating habits becomes one of the most important lessons a child needs to learn.Most parents struggle with managing good eating habits and nutrition (营养) for their children.Parents should make a plan for their children's nutritional needs.
Start your child's day with a good breakfast.Breakfast is necessary to provide the nutrition for an active day.Studies show that children do better in study when they begin a day with a good breakfast.
Allow your child to help you plan and prepare a meal.He will be glad to eat foods that he has helped to put on the table.
The mealtime environment has a lot to do with how your child will feel about food.Try to serve your meals at the same place at the same time of a day.Keep the meal itself as the main event and leave the toys and television for later use.
Snacks are also important.We can give our body and brain energy (能量) by eating snacks between meals.Children are often hungriest in the afternoon after school and in the evening.
Offer snacks at regular time between meals.This way,your child won't refuse a meal because he knows a snack is soon to follow.More importantly,when offering snacks,you should be careful with what to choose.

25.The main idea of the second paragraph is thatC.
A.most children go to school without eating breakfast
B.one shouldn't eat too much for breakfast
C.a good breakfast is important to children
D.most people haven't realized the importance of having a good breakfast
26.To help their children form healthy eating habits,parentsB.
A.should encourage their children to eat more often at school
B.can ask the children to help with meal planning and preparation
C.must make the mealtime environment as quiet as possible
D.should serve some snacks while having a meal
27.What would most probably be talked about in the next paragraph of the passage?A
A.Examples of healthy snacks.
B.Why snacks are important.
C.Advice on how to keep healthy.
D.What to eat for lunch and supper.

18.When you tidy your messy bedroom,it gets a lot easier to find things.Dreams may work the same way for a messy brain,helping you learn by organizing memories and ideas.
    To test how much dreams can help learning,Robert Stickgold had some students play a shape-fitting game called Tetris (俄罗斯方块) for a few hours and then go to sleep.Soon they were dreami ng of falling Tetris shapes.Interestingly,the worst Tetris players had the most Tetris dreams and improved their game the most.Similar tests have shown the same results for all kinds of skills.
    As we dream,many important tasks are getting done.The brain decides what to keep and what to forget.It is connecting new experiences to older learning.In fact,the brain is learning all night long.
    Another important task of dreams may be to help us deal with emotions(情绪).People who have had an upsetting experience often dream about it afterward.Often the dream event changes somehow----another way the brain tries to make the memory less upset.So if your best friend moves away,you might dream that you're the one who's moving.In fact,dreams have a proven power to improve mood,and people who dream about what's bothering them usually feel better sooner than those who don't.
    Everybody dreams for a couple of hours every night----in the course of your life,you'll spend about 25 years asleep and 6 years dreaming.There's probably no single answer to the question why we dream,but there doesn't have to be.One dream might help you remember your math facts,while another might lead to a new invention,or give you a fun,crazy story to tell your friends.It's all in a night's work for our busy,mysterious brains.
1.R obert Stickgold's test shows thatA.
A.dreams can help improve skills                  
B.tasks can only be settled through dreams
C.games are useful for memory                 
D.players stop learning in dreams
2.We can learn from Paragraph 4 thatC.
A.dreams can get rid of sufferings                
B.only drivers can deal with emotions
C.one may be less upset after a dream             
D.dreams can copy what one experienced
3.What does the text focus on?D
A.Dreams and memories.
B.The patterns of dreams.
C.Dreams and emotions.
D.The benefits of dreams.
