Very few people enjoy exams. I don’t, either. And although I tell myself not to worry about them, I always do! So I am not surprised that my students worry about them, too, even though they usually don’t need to. Because they are afraid of failing. However, since it is hard not to worry at all, we all must try not to worry too much. Why? Because worrying makes exams worse! How to do this?
Ask the teacher about how to revise and about exam skills---- how to work when you are in the exam.
Good students don’t wait until the week before an exam. They study all through the year. It is not possible to learn everything at the last minute. So don’t leave it till then!
If you start planning and working for each exam early and you make sure that you understand what you are studying , then, when it is over, you’ll be able to say, “What a good exam that was!”
Take a short rest during your time of work and revision(复习). If your mind is tired, it will not remember well. Work at the time when you know you will work at your best.
If you are studying in the evening, don’t go straight to bed afterwards. Your mind will still be “going round and round”----thinking that will relax you, and make you think of other things.
If you feel bad, talk to someone about your worries. But don’t be too relaxed! Some stress over exams makes you work hard for them.

Have you ever counted the number of digits （数字）in your mobile phone number？ Your number has 11 digits． You may sometimes find it hard to remember your number． That's because China has the longest mobile phone numbers in the world． Why is that？
The 11 digits can be divided into three parts． Each part has a different meaning． The first three numbers tell you which mobile phone service provider（提供者） you are using． For example， 135 is for China Mobile Communications Corporation and 188 is for China Unicom． The fourth to the seventh digits tell you where the number is registered （注册）． And the last four digits are random（随机的）．
The main reason for using 11 digits is that we have the largest population in the world． We once had 10numbers． But as our population grew， there were not enough numbers for us to use． So we began to use 11 digits starting from 1999． Eleven digits can be used to make tens of billions of mobile phone numbers． That's enough for each person to have seven or eight phone numbers to use in China．
And mobile phone numbers can be recycled． Usually， the service provider will reuse a canceled number after three to six months． If you call a number that you haven't contacted （联系）for a long time， you may find that its owner has changed．
Besides China， Britain and Japan also use 11﹣digit mobile phone numbers． But their numbers always start with 0． So they cannot create as many numbers as we can． Countries like the United States， Australia and India use phone numbers with 10digits． Canada's mobile phone numbers are perhaps the shortest in the world： they use seven digits．
（1）Is China the only country that uses 11﹣digit mobile phone numbers in the world？
（2）What can we know from the fourth to the seventh digits of a mobile phone number in China？
（3）Why does China use 1l digits for mobile phone numbers？
（4）When can a mobile phone number be recycled in China？
（5）Which country perhaps has the shortest mobile phone numbers in the world？
What was discovered by accident？ The answer is penicillin（青霉素）． It kills germs． By killing germs， it saves lives． Suppose you are sick． You go to a doctor． She examines you． She says you have a" staph'" infection（葡萄球菌感染）． She gives you some medicine． You take it． The medicine knocks out the staph． Soon you are well． Before penicillin， this would not happen． Staph was almost sure death．
Everyone wanted a medicine． Laboratories worked day and night． They grew the staph in small dishes． Then they tried to kill it． Nothing worked．
The laboratory dishes had covers on them． They kept things from falling into dishes． Molds（霉菌）were a big worry． They are always in the air． You can't see them． They're too small． There are thousands of different molds． Molds can make an experiment （实验）fail． That's why dishes are covered．
Dr． Alexander Fleming was working to kill the staph germ． He worked for years． One day he took a cover off a dish． He looked inside． There was a thick growth of staph germ． There was also some mol
d． Then he saw something strange． Where the mold was， there was no growth of staph． This is what Fleming probably thought． "By accident， I found a mold to kill the dreaded staph．"
This is how penicillin was found． But here's the real miracle（奇迹）． There are thousands of kinds of molds． But only one kind can kill staph． The mold must have fallen into the dish a few days before． The cover was probably off only a few seconds（秒）． In those few seconds the right mold fell into the right dish． Another man might have thrown the dish away． But Fleming was very careful and smart． He understood what the mold did． How lucky the humans were !

People already know a lot about animals． However， there are still some things about animals that may surprise you． Here are some facts about animals you probably didn't know．
Cows do have best friends and feel stressed when they are separated． Scientists have found that cows are very social animals and a cow always makes friends with other cows． When a cow is with its friends， it feels relaxed， compared with when it is alone．
During breeding season， a male penguin（企鹅）will offer a small stone to a female penguin as a gift． If she takes it， they will become partners． When the female penguin lays an egg， she and her partner may carry it on their feet， because some penguins don't build nests（鸟巢）．
Crocodiles（鳄鱼） swallow（吞）stones． Crocodiles always swallow their food instead of eating it like other animals． They swallow stones which break the food into very small pieces in their stomachs． These stones may stay in their stomachs all their lives．
Elephants use plants to treat pain or other illness． Scientists once found a pregnant（怀孕的） elephant in Africa who ate a kind of plant which was not part of her normal food． Four days later， she gave birth to a baby elephant． The same plant was used by the local pregnant women．
