19.About the year 1900,a small,darkhaired boy named Charlie Chaplin was often seen waiting outside the back entrance of London Theatre.He looked thin and hungry.He was hoping to get work in show business.He could sing and dance; above all,he knew how to make people laugh.But he couldn't get work and so he wandered about the city streets.Sometimes he was sent away to a home for children who had no parents.
But twenty years later this name Chaplin became the greatest,bestknown,and bestloved comedian in the world.Any visitor to the cinema must have seen some of Chaplin's filmstrips(膠片).People everywhere have sat and laughed at them until the tears ran down their faces.Even people who don't understand English can enjoy Chaplin's films though most of them are silent.It isn't what he says that makes us laugh.His comedy doesn't depend upon words and languages.It depends upon little actions which mean the same thing to people all over the world.Acting out,without words,common human situations plays an important part in the dances and plays of many countries.It's a kind of world language.
Chaplin lived most of his life in America and died in Switzerland on Christmas Day,1977,at the age of eightyeight.The world was astonished at the news of the death and burst into sadness.
21.Why was young Chaplin waiting outside the back entrance of the theatre?C
A.Because he had no money to buy a ticket.
B.Because he wanted to get a returned ticket.
C.Because he wanted to play a part in a play in order to make a living.
D.Because he wanted to see the famous actors or actresses after the performance.
22.It wasD that made people enjoy his films.
A.wonderful dialogues
B.the beautiful music
C.his funny appearance
D.his own manner of acting
23.The reason why Chaplin is regarded as king of comedy is thatD.
A.his films are most silent
B.he knew how to make people laugh
C.he could not only act but also write comedies
D.he acted out the common human situations best in his comedy.

9.What is ecofashion?Eco-fashion is about making clothes that take into account the environment,the health of consumers and the working conditions of people in the fashion industry.It is a complex phenomenon and the common use of the fashionable terms-‘ecological'and‘ethical'.Ecological fashion usually refers to textile (織物) and clothing production processes and the environmental issues surrounding them;ethical fashion generally relates to the working conditions involved in the producing processes.
What are the problems with fashion?A closer look at the fashion industry points out many problems that are common practices in the creation of our fashions from the field to the factory.Firstly,the production of textiles pollutes the environment heavily.Cottonplanting uses pesticides;sheepfarming and woolcleaning contribute to global warming;syntheticsmaking (人造纖維生產(chǎn)) brings about waste which does harm to our environment.Secondly,every stage of clothing production has a significant effect on the environment.They all use a great deal of energy,and some also involve chemicals which evidently do harm to the surroundings.In addition to this,there is a lot of waste produced in the process,especially in the form of polluted water.Thirdly,growing consumption levels and our shopping habits further worsen the bad effects.We are now buying clothes in increasing quantities without realizing the scale on which it affects natural environment,and we are also quick to throw away clothes that have been worn only a couple of times.
Then,how to solve the problems?Other industries that design products are ahead of the fashion industry when it comes to choosing sustainable materials,designing for minimum waste,choosing energy efficient manufacturing and creating products for longevity.The fashion industry has been slow to adopt these changes and part of the problem is the very nature of fashion.To a large degree,it is the fashion producers that really have the power and the responsibility to shape our future.There are numerous ways in which these producers can reduce their ecological footprint,from switching to green energy and reducing energy use,through selecting sustainable materials and choosing local suppliers,to recycle and minimize waste.On the other hand,as consumers we can all make contributions by selecting environmentally friendly clothing and reducing clothing consumption.
There is some concern that eco-friendly fashions are just a trend that we will eventually grow tired of but we can make sure that doesn't happen.Now many people are beginning to shop for organic food products because the benefits of eating food free of chemicals are straightforward and immediate.They relate directly to our personal health.In fact,choosing ecofashion can also contribute to our personal health,though it is mostly done by way of keeping the health of the planet.
