Everyone has moments of forgetfulness from time to time, especially when life gets busy.

【小题1】, having a poor memory can be frustrating. However, research has shown that there are ways to improve your memory.

Sleep on it

Sleeping well helps make episodic memories stronger. 【小题2】, especially relating to learning motor skills, such as learning to play a musical instrument or ride a bike. Having a full night’s sleep soon after gaining a new skill helps strengthen the processes involved.

Believe to remember

Positive thinking appears to improve memory performance. Researchers found they could improve the performance of people aged 60 and above in memory tests by presenting them with positive age-related words such as “wise”, and “sharp-witted”. 【小题3】. Brain scans have shown differences in activity levels in brain regions, according to whether or not individuals believe they have good recall abilities or not.

【小题4】

Memories can be weakened if the brain doesn’t have enough downtime to strengthen them. More than a century ago, German scientists showed that people performed almost twice as well in memory tests if they took breaks.

Stay social

【小题5】. US scientists who asked people in their 50s and 60s to do memory tests every other year found there is a slower decline in recall abilities of their most so ciable persons. Having good friends, volunteering and other forms of social engagement also protect memory.

   Iwould love to be happier，as I'm sure most people would，so I think it will be interesting to find some ways to become a happier person.

1. Exercise more

Exercise has such a deep effect on our happiness and well-being that it's actually been proven to be an effective strategy（策略）for overcoming depression. 【小题1】It can also improve your body image，even if you don't lose any weight.

2. Sleep more

We know that sleep helps our bodies to recover from the day and repair themselves，and that it helps us focus and be more productive. 【小题2】

3. Spend time with friends and family

【小题3】Several studies have found that time spent with friends and family makes a big difference to how happy we feel.Almost all the other things that we think make us happy are actually just ways of getting along well with more families and friends.

4. Go outside

Spend time in the fresh air to improve your happiness. 【小题4】One study found that spending 20 minutes outside in good weather not only improves our positive moods，but broadens thinking and improves working memory.

5. Help others

To make yourself feel happier, you should help others. Spending money on other people makes us happier than buying stuff for ourselves. 【小题5】A study of volunteering showed that volunteers were affected and felt unhappy when their opportunities to help others were taken away.

   A strong memory depends on the health and vitality（生命力）of your brain. They say that you can't teach an old dog new tricks，but when it comes to the brain，scientists have discovered that this old saying simply isn't true. 【小题1】

Give your brain a workout. Memory, like muscular strength, requires you to“use it or lose it”. The more you work out your brain, the better you' ll be able to process and remember information. 【小题2】

Don't skip the physical exercise. While mental exercise is important to brain health, that doesn't mean you never need to break a sweat. Physical exercise helps your brain stay sharp. It increases oxygen to your brain and reduces the risk of disorders that lead to memory loss.

Get enough sleep. There is a big difference between the amount of sleep you can get now and the amount you need to function at your best. 【小题3】

Keep stress in check. Stress is one of the brain's worst enemies. Over time, stress destroys brain cells. Studies have also linked stress to memory loss.

Have a laugh. 【小题4】 That holds true for the brain and the memory, as well as the body. Unlike emotional responses, which are limited to specific areas of the brain, laughter involves multiple regions across the whole brain.

【小题5】 Just as the body needs fuel, so does the brain. You probably already know that a diet based on fruits, vegetables, whole grains,“healthy”fats and lean protein will provide lots of health benefits, but such a diet can also improve memory. For brain health, though, it's not just what you eat — it's also what you don't eat.

I used to have the same problem! _____________________________________________________________

Wish you success!

   Do you want to be at the top of your class？Add these tips to your life and you should be on your way to being a top student！

【小题1】 I cannot stress（强调）enough how important it is to pay attention to what your teacher is teaching you. Take part in class discussions if you have something worthwhile to add. Pay attention during class, especially during lectures.

Taking notes is important. You don't need to write down every word your teacher says but write down what he writes on the board, or any special fact you think you might need for a test.【小题2】 This way it will help you learn more effectively by actually thinking about what you are writing.

Don't skip school（逃学）.You will be missing out on stuff.【小题3】 However, you will have more work because you have missed lectures. Also, try not to be late for class. It's most likely that your teacher won't appreciate it and you will get yourself behind.

【小题4】 If you have an "I don't care about school or this class" attitude, then teachers will be less willing to offer you extra credit（学分）.The same goes for lazy attitude. Have a respectful attitude to the teacher and other students. Try not to laugh when other students make a mistake.

Always ask questions.【小题5】 If you don't understand, ask someone. Read your textbook and notes, and then if that fails, seek help. Ask a teacher, friend, classmate, parent, etc. Get a tutor if you need one.
