“What’s happening? Is something wrong with my eyes?” You may wonder at what you see. Don’t worry. Here is how it goes:

Movie makers often make use of visual illusions. They make the objects around actors much smaller or bigger than usual. This makes us believe that the actors are much larger or smaller than they usually are. The movies Jurassic Parkand Honey I shrunk the kids just make use of visual illusions.Why does the centre circle in Diagram A look smaller than that in Diagram B?
| A．something is wrong with our eyes |
| B．the two circles are not the same size |

Most of us use alarm clocks or mobile phones to wake up at the right time for school or work． We look at our watches to know the right time for the bus or train． However， there is also a right time to eat， sleep， exercise， and take medicine． We can't look at a clock for the right time for these activities． We must listen to the clock inside our bodies， the biological clock．
Barbara Wells exercised every morning． She woke up at 6：00 a． m． She ran about two miles before she went to work． But Barbara's legs and back started to hurt． She did some exercise before she ran．But her legs and back still hurt． She ran slower， but the pain didn't stop． Barbara talked to her doctor．The doctor said， "Don't run in the morning． Try to exercise later in the day． That is the time when your body is at the right temperature for exercise after work． Her legs and back didn't hurt any more．
Today， doctors are learning more about chronobiology（生物钟学），the study of biological clocks．They are learning about the importance of time for our bodies． For example， it is best for people to go to sleep on time every right and to eat only when they're hungry．Also，doctors discovered that some illnesses，such as heart attacks， occur （v． 发生） most often in the morning．This information tells them that the best time to take heart medication may be at night． When patients take heart medication at night， they may prevent a heart attack in the morning．

Dear Nancy's parents，
My daughter had a bullying （欺凌） problem a couple of years ago． It wasn't easy，but I ended it．When things are a serious as you describe， it is no time to be silent． These kids probably know each other from school， so take the rude text messages sent by the bully directly to the headmaster and show him Describe to him bow it is affecting your 13﹣year﹣ old daughter．Tell him you will not stand it and you want him to put an end to it now．
Bullying is a dangerous and serious offensethese days，and any good headmaster will take your charges seriously． He will probably address the issues with the parents． If they are crappy parents， then they may do nothing to their child． You may have to repeat this process several times， but you need to keep a check on those text messages and don't allow your child to delete them．
Now is the time to draw your child close and take care of her， because she needs it． My daughter did not like me being involved（参与的）either， but you are the only hope she has of solving this problem， so do it and mean business．Always be polite but straightforward．The headmaster and the parents must know you mean business．
If repeated meetings with the headmaster （and parents， if he allows it） does not solve the problem， then I would consider hiring a lawyer． That will send the message across loud and clear．When you are talking about financial loss， most parents will stand up and take notice and act to keep their kid under control!
Good luck ﹣ I wish you the best in this terrible situation．
Yours，
Rachel

Today， the world's diversity（多样性） of food crops is quickly decreasing． But scientists around the world are taking action． They are building seed banks． At seed banks， scientists store the seeds of many different crops．
There are now 1，400 seed banks around the world． However， some banks are in warm countries． If the electricity fails， the seeds will get too hot and die．Other seed banks are in countries troubled by war．Sometimes people damage the seed banks． If this happens， valuable seeds can be lost forever!
