15．American scientists have developed the first material that repairs itself．The material is a form ——青夏教育精英家教网—

15．American scientists have developed the first material that repairs itself．The material is a form of plastic that has been engineered to fill breaks in its surface．
Plastics are used today in everything．Scientists wanted to find a way to make objects made of plastic last longer．The researchers hope their new discovery can be used to make objects that are difficult or impossible to replace．
The surface of plastic objects breaks over time．Very small breaks develop every time a plastic object is used．The researchers wanted to find out how to stop plastic from developing small breaks that weaken and destroy it．They found the answer in the chemical structure of plastic itself．The research team found a way to make plastic that contains very small balloons filled with monomer（单体） liquid．When the new plastic cracks，the monomer liquid is let out and flows into the crack．Thus the break is repaired．The repaired plastic has seventy-five percent of the strength of undamaged plastic．
The new self-repairing plastic is not yet ready for production．But it has several possible uses．One could be in space vehicles where parts cannot be repaired or replaced．Another possible use might be in bridges．And it could be used in people，to replace bone joints that have become broken or damaged．
33．The passage mainly talks aboutA．
A．plastic that repairs itself

C．the new material cannot be used elsewhere
D．the plastic parts in them are easily broken or damaged．

14．Sometimes people call each other"scared cat"，but have you ever thought about this expression？When a cat is frightened，its heart starts beating faster，its muscles get tense，and there are changes in the chemicals in its blood-stream．If the danger continues，this animal will do one of the two things．It will defend itself，or it will run away as fast as it can．
   Something like this also happens to people．When we are excited，angry，scared，or aroused by other emotions，our bodies go through many physical changes．Our hearts beat faster，and our muscles get tense．All of these changes make us more alert and ready to react．We，too，get ready to defend ourselves or run．Human beings，however，have a problem．If we give way to our feelings and let them take over，we can get into trouble．Have you ever said something in anger and regretted later？Have you ever shouted at a teacher or told somebody you were lonely and then wished later you had kept your mouth shut？It isn't always wise to express your feelings freely．
Does this mean that it's always smarter to hide our feelings？No!If you keep feelings like anger hidden away or bottled up inside，your body stays tense．Physical illnesses can develop，and you can feel disturbed badly inside．Itcan actually be bad for your health．Feelings that you keep all bottled up inside don't just go away．It's as if you bought some bananas and stuck them in a cupboard．You might not be able to see them，but before long you'd smell them．And if you opened the cupboard，chances are you'd see little fruit flies hovering（盘旋） all over them．They'd be rotten．You can try to treat emotions as if they were bananas in the cupboard．You can hide them and you can pretend they don't exist，but they'll still be around．And at last you'll have to deal with them，just like those bananas．

13．English is the most widely used language in the history of our planet．One in every seven human beings can speak it．More than half of the world's books and three quarters of international mails are in English．Of all languages，English has the largest vocabulary-perhaps as many as two million words．
   However，let's face it：English is a crazy language．There is no egg in an eggplant，neither pine nor apple in a pineap ple and no ham in a hamburger．Sweet-meats are candy，while sweetbreads，which aren't sweet，are meat．
   We take English for granted．But when we explore its paradoxes （矛盾），we find that quicksand can work slowly，boxing rings are square，public bathrooms have no baths in them．And why is it that a writer writes，but fingers don't fing，grocers don't groce，and hammers don't ham？If the plural （复数形式） of tooth is teeth，shouldn't the plural of booth be beeth？One goose，two geese-so one moose，two meese？How can a slim chance and a fat chance be the same，while a wise man and a wise guyare opposites？How can overlook and oversee be opposites，while quite a lot and quite a few are alike？How can the weather be hot as hell one day and cold as hell the next？
English was invented by people，not computers，and it reflects the creativity of human beings．That's why，when stars are out，they are visible； but when the lights are out，they are invisible．And why，when I wind up my watch，I start it； but when I wind up this essay，I end it．

8．Finland lies in the north of Europe，and has Russia to the east．It is two different places in winter and summer．Summers there are fairly dry and hot，although by August things can already begin to get cold and unpleasant．Of course，winters are cold，but the cold is dry．In most parts snow comes in October and clears by the end of March，but in the northern parts snow can fall as early as September and stay until late May．

7．October 15^th is the Global Handwashing Day．Activities are planned in more than 20 countries to get millions of people in the developing world to wash their hands with soap．For example，donators will give 150，000 bars of soap to schools in Ethiopia．
Experts say people around the world wash their hands every day，but very few use soap at so-called important moments．These include after using the toilet，after cleaning a baby and before touching food．
Global Handwashing Day is the idea of the Public-Private Partnership for Handwashing with Soap．Partners include the United Nations Children's Fund，American government agencies，the World Bank and soap makers Unlever and Procter and Gamble．The organizers say all soaps are equ ally effective at removing disease-causing germ．They say the correct way to wash is to wet your hands with a small amount of water and cover them with soap．Rub it into all areas，including under the fingernails．Rub for at least twenty seconds．Then rinse well under running water．Finally，dry your hands with a clean cloth or wave them in the air．
The Partnership for Handwashing says soap is important because it increases the time that people spend in washing hands．Soap also helps to break up the dirt that holds most of the germs．And it usually leaves a pleasant smell．The Partnership for Handwashing also says washing with soap before eating or after using the toilet could save more lives than any vaccine（疫苗）or medicine．Hand washing could also prevent the spread of other diseases．When people get germs on their hands，they can infect themselves by touching their eyes，noses or mouths．Then they can infect others．

6．People are overweight for many reasons，the most important one of which is that they eat the wrong foods，get the wrong types of calories per meal，and they also eat meals at the wrong time each day．Food is more powerful than any weight loss pill，because the food that you eat can either make you thin or fat．This is true because your body is like an engine，and it only needs certain foods at certain intervals（间隔） each day．
Low-calorie Diets Do Not Work
The reason people cannot lose weight by starving themselves is that their metabolism（新陈代谢） will detect any major drop in calories and it will then adjust itself by burning fewer calories each day．That is the reason why you can eat 1，000 calories per day and not lose any weight，while your friends can eat 2，500 calories per day and not gain any weight．
Low-fat Diets Do Not Work
Many people in today's society are buying mostly low-fat or non-fat food at the grocery store．Everybody knows how much fat is inside the food they buy．However，people are getting fatter than ever before by doing this．They are not losing weight by changing to this low-fat lifestyle．
Losing weight has nothing to do with these things．One of the most important things you can do to control your weight is to eat the proper foods，such as fruit and vegetables，eat them at the right time，and exercise every d ay．If people make this a habit，they will lose weight．
25．What is the main reason why people are overweight？A
A．They eat the wrong foods at the wrong time．
B．They eat food with lots of calories．
C．They don't take weight loss pills．
