How to improve your memory

  There are many things you can do to improve your memory.Among them are various memorizing methods as well as taking special care of your health.

    1   is important that you regularly stimulate your brain to make your memory more efficient.You   2   do this by doing activities that you do not normally do and by changing your daily habits.  3   a new skill helps your brain to develop.When trying to memorize   4  , you should focus your attention because this will lower your chances of making accurate memories.

  An excellent   5   to help is to link information with pictures.These are referred to as mnemonic techniques(记忆术).Try to see the images in your mind.Taking notes, being organized and keeping a diary will   6   be useful tools.

    7   food and plenty of vitamins are essential for your memory to work properly.Drinking a lot of water also helps maintain your memory.You must allow your brain to have   8   sleep and rest.When you are asleep, your brain stores memory.Not enough sleep can, therefore, cause   9   with storing information.In addition, being tired will stop you from being able to concentrate well.Caffeine in tea and coffee are very   10   at preventing sleepiness and helping concentration,   11   they can also cause problems with memory.

  In order to concentrate well, you must be   12  .Generally keeping fit and regular health checks are both important as well-not just for improving your memory.

  For hundreds of years, scientists have been trying to answer what things can influence people’s feelings.How you feel is controlled by many things.Your feelings can be affected by your personality, by the actions of others and by events around you.Perhaps you don’t know your feelings can be influenced by the weather as well.

  People often say they feel good when the sun is shining and sad when it is cloudy.In fact, sunlight makes us feel good.When sunlight hits our skins, our bodies produce a vitamin.Vitamins are natural chemicals(化学物质)which we all need to stay healthy.Sunlight helps our bodies produce vitamin D.Vitamin D helps our bodies make a special chemical.This special chemical affects our brains(大脑)and makes us feel happy.For example, there are long, dark winters of little sunlight in Sweden and Norway, so many people in these countries often feel sad.Without much sunlight, their bodies produce less vitamin D.Without enough vitamin D, their bodies make less of this special chemical which makes them feel good.To help the people in these countries feel better, special “sunrooms” with artificial(人造的)lights have been built.People can go there and get “sunlight” for an hour or two!

  The weather can also affect people’s feelings in other ways.Hot weather can make people angry because people feel uncomfortable when they are hot.In the same way, rain can make people angry because being wet can be unpleasant.As you can see, the weather can have an effect on the chemicals which control our brains.Through these ways, the weather can influence our feelings.Sadly, while the weather can change us, we can hardly change the weather.

(1)

Which of the following is true about vitamin D according to the passage?

[  ]

A.

It is a kind of artificial chemical.

B.

It makes us worried by affecting our brains.

C.

It is needed by us all to keep fit.

D.

It is in the sunlight.

(2)

What can we infer(推断)from the passage?

[  ]

A.

We feel good when we are in the bright cool weather.

B.

We will be happy when we are caught in the rain.

C.

All people in Norway and Sweden feel sad in winter.

D.

The more vitamin D you have, the happier you’ll be.

(3)

What may be the best title for this passage?

[  ]

A.

Why Do We Feel Sad?

B.

The Weather Influences People’s Feelings

C.

People Need More Vitamin D

D.

We Can Hardly Change the Weather

完形填空。
  One in four Chinese primary school students say they are too busy to eat
fruit every day, while many dislike fruit for the simple reason that their    1    tell
them to eat it.
  That is the result of a recent survey    2    the Chinese Association for
Student Nutrition & Health Promotion(中国学生营养和健康促进协会), who
last month issued a questionnaire among 1,500 children in Beijing, Shanghai and
Guangzhou. They    3    28 percent didn't eat fruit every day and of those who did,
one in seven did not eat enough.
  Among students who didn't eat fruit every day, 50 percent said it was
because they "didn't have time" and 40 percent of those who didn't like fruit said
it was because "my parents    4    me to".
  "Fruit is a natural source of many nutritional elements(营养元素), can
balance a person's nutritional intake and help to    5    overweight(超重)," says
Association director Du Yuxia.
  He says about 20 percent of primary school students in Beijing and
Guangzhou are overweight, while the figure is     6    30 percent in Shanghai.
  Hu Xiaoqi, a nutrition expert with the Chinese Center for Disease Control
and Prevention (CDC), believes a student should eat at least 150 grams of fruit a
day. Moreover, fruit juice is not an adequate substitute because the fruit    7   
contains more fiber and vitamins than juices, which are usually high in sugar and
contain preservatives.
  Hu says primary school students should be encouraged to eat one or two
fruits every day.    8    many students found they didn't have time to eat fruit
before breakfast or in the evening, they should be encouraged to    9    to school
and eat it during class breaks . Finally, she suggests that parents encourage their
children to eat fruit, instead of forcing them.
  Ma Guansheng, deputy   10   of the CDC's Nutrition and Food Safety
Institution(营养和食品安全机构), says: "6-12 years old is a crucial time for
physical development. Children at this age need an adequate and balanced
nutritional supply to guarantee the normal growth of the body."

 If you go to a fast food restaurant, you will probably see a lot of teenagers. Today, many teenagers are overweight, and this is because of their bad eating habits. Most teenagers are fond of food with a lot of fat, oil, salt and sugar. People call this kind of food “junk food”.

  But bad eating habits go beyond fast food. We find many teenagers eat unhealthily. Some don’t have breakfast before they go to school. During the day, some don’t have a proper meal for lunch. In a recent survey at one school, scientists found that over two thirds of the students didn’t follow a healthy diet. They didn’t like vegetables, and many of them didn’t like to eat fruits. They preferred to eat food with a lot of salt, sugar, or fat.

  Parents today also worry about their children’s diet. Some doctors give the following advice:

  Teenagers shouldn’t eat too much junk food.

  Teenagers shouldn’t eat food with too much salt. Salt can cause high blood pressure in the future.

  Teenagers should eat food without much fat, oil and sugar.

  Teenagers need to eat some fruits and vegetables every day. Fruits and vegetables are rich in vitamins(维生素)and have little fat.

  Teenagers need to drink more milk. Milk will help their bones grow.

  Teenagers need to eat breakfast every day. It is good for their body and mind.
