Some English words have more than one meaning．These are called multi﹣meaning words．

Multi﹣meaning words have the same pronunciation with different meanings．For example，let's look at the word "ball"．You could have a "ball" which means you would have a good time．You could toss a "ball" which means you throw an object．You could be on the "ball" which means you know what is happening．You could go to a "ball" which means a dance．

______Take the word "can"．You "can" ride a bike which means you are able to ride a bike．You have a "can" of soup which means the soup is in a round﹣shaped holder．You can do the "can﹣can "which is a dance from the 1920s．And you might get "canned" if you do a poor job at work，which means you might lose your job．

How about "fly"？You can "fly" an airplane or you can hit a "fly" that is on your food in your house．Or，you can "fly by the seat of your pants" which means you don't make a plan before taking an action．And，you know that the "fly" of a zipper is the top part of the zipper．

There are hundreds of words that are multi﹣meaning words．The word "set" has more meanings than any other word in the English language．When you have time，why don't you try to think of all the ways the word "set" is used？

If you look at the title of this book Can a Fly，Fly？…you know that the answer is "Yes" because you have seen an insect named a "fly" go up in the air and move around through the air…which is what "fly" means．Can a Fly，Fly？Of course，it can!

Luca Gramberini has been scuba diving（戴水肺潜水） since he was a kid．His family owns a scuba company．For the past three summers，Luca has added gardening to his underwater activities．He helps run Nemo's Garden，a project to grow plants in the sea．

From May through September，Luca and other divers are working on Nemo's Garden in the Mediterranean Sea，150 feet from the coast of Noli，Italy．Five large balloon﹣like objects，called biospheres（生物圈），hold plants such as beans and strawberries．The biospheres are filled with air and placed 20 feet below the surface．"My father came up with the idea because he loves gardening very much，"Luca said．

According to Luca，the sea is a good place to grow plants because underwater temperatures remain stable，changing little from day to night．The biospheres act like greenhouses．Inside the air﹣filled biospheres，fresh water keeps evaporating（蒸发），providing the plants with a good environment to grow in．"We have already seen the plants grow faster and better，"Luca says．"And there are fewer storms that can knock down the biospheres during the summer．"

Luca hopes Nemo's Garden will provide a new way of growing crops．"There is not enough land on the Earth，"he says．"And in many developing countries，bad conditions make it difficult for crops to grow．"

Though the project has just started，Nemo's Garden has achieved success and is moving to different areas．"We're going to try growing other plants．"Luca says．"We hope to set up biospheres around the world．There are many possibilities．"

Leon was a postman．Every day Leon would wake up and feed his 37 cats．Leon didn't really want 37 cats，but one by one they had appeared on his doorstep，and Leon had taken them in．

Every day，after feeding the cats，Leon would collect the letters from the red postboxes in the village and take it home．"If only I had 37 helpers instead of 37cats，my job would be so much easier，"Leon thought．Just then，the cats started meowing for their dinner．That gave Leon an idea．That night，Leon worked late making 37cat﹣sized postal backpacks．Then，he went around to each postbox，putting up signs that read：Postbox closed!Please use the postal cat service．

The next day，Leon put a backpack on each cat and dropped off the cats around the village．Leon knew that the cats would be happy walking around all day．He also knew that they would always come home for dinner．Leon spent the day relaxing，waiting for his helpers to return．Leon was right．The cats did return，but they did not bring home many letters．Some got the letters wet．Some bit off the corners of the letters．Some even lost their backpacks．""Cats are just too unreliable（不可靠的），"Leon thought．

Daming想在国外eBay网上购买CD，但他从网上搜到"淘淘"经验有点杂乱，请帮助Daming将这些杂乱的信息整理成一副购物流程图，完成购物，第一步已给出．

A．Compare the CDs in the list．You can look at the prices or other customers'opinions．This can help you decide which one you want to buy．

B．Go to www．eBay．com and create an eBay account．You need to fill in an online form with your information．To pay for your order，you also need to get one on PayPat．

C．After you have an account，you can look for the CD you want．Type the name of the CD in the search box．You will see a list of CDs．

D．When you decide which one to buy，you can click"Buy It Now"and then finish your order with the correct address（better both in English and Chinese），your telephone number and suitable ways of post．Finally．pay for it and you will receive it in about 20 to 30 days．

E．However，if you are not satisfied with it，it is possible to return the CD in 5 working days．I hope this step is never needed．

F．Once you receive the CD，check it carefully．If you are satisfied with it，you can go back to eBay website and give your opinions on it．

Harmful microbes like bacteris，viruses and other germs are pathogens．They may enter your bodies and make you ill．The immune system is the body's defence system that protects you from illness and disease caused by the pathogens．

The immune system is made up of non﹣specialized defences such as skin，tears and the acidic juice produced by the stomach，keeping you from the pathogens．It also has some highly specializde defences，which are different kinds of immune cells，grouped into phagocytes and lymphocytes．Phagocytes are a type of white blood cell．They are swimming around in your blood stream，always on the lookout for antigens﹣the pathogens that have entered your bodies．Whenever they see one，ther will eat it．However，some antigens are hard to find and kill．Then lymphocytes，which are also white blood cells and the main types are B cells，T helper cells and T killer cells，Will be the killers of the sncaky antigens．

B cells，T helper and T killer cells work together to find and kill these antigens．B cells produce substances，called antibodies，which stick to the antigen．When that happens，it will tell the T helper cells to come over and either：1．help the B cells kill the antigen，or 2．call the phagocytes or T killer cells to move in for the kill．Once a B cell or a T cell attacks an antigen，they create cells to"remember"it．Those"memory cells"hang out in your blood if they see the same antigen again，they quickly recognize，it so your immune system can act faster at killing it．

The immune system is more powerful than you probably imagine．Scientists from the University of Pennsylvania recently took immune cells from three patients with leukemia，then genetically cheanged them into "serial Keller" cells to attack cancer cells．The study was small but the results were groundbraking．The modified immune cells increascd at least 1，000 times in the body and killed all the cancer cells．Therefore，more "memory cells" were created．

The immune system can be developed．Eating lean protein food （beef，beans ）and food rich in vitamins A，C，and E（sweet potatoes，carrots ），taking a 30﹣minute walk every day and reducing your stress levels，etc．will help you achieve it．
