EXTENDED FAMILY In an extended family, all the people share one household. Apart from parents and children, there may be other family members grandparents, aunts, uncles, cousins, etc. That is to say, a large family may have more than two generations, and often there are more than two adults from different generations of a family. The family members live together for many reasons. They may help to bring up children or to take care of an ill relative. They may also help with saving money. Sometimes children are brought up by their grandparents, for their parents have died or can never take care of them. Many grandparents look after the children,particularly when both parents are busy working. This large family is called extended family. It can be found all over the world. The number of these families has increased by 40 percent in the past ten years. Most of such families live happily together.1. In an extended family, people live in different houses.()2. An extend family includes at least three generations.()3.In an extended family, children are looked after by their grandparents because their parents are traveling around.()4.

共用题干第三篇People have been painting pictures for at least 30,000 years.The earliest pictures were painted by people who hunted animals.They used to paint pictures of the animals they wanted to catch and kill.Pictures of this kind have been found on the walls of caves in France and Spain.No one knows why they were painted there.Perhaps the painters thought that their pictures would help them to catch these animals.Or perhaps human beings have always wanted to tell stories in pictures.About 5,000 years ago,the Egyptians and other people in the Near East began to use pictures as kind of writing. They drew simple pictures or signs to represent things and ideas,and also to represent the sounds of their language.The signs there people used became a kind of alphabet.The Egyptians used to record information and to tell stories by putting picture-writing and pictures together. When an important person died,scenes and stories from his life were painted and carved on the walls of the place where he was buried.Some of these pictures are like modern comic strip stones.It has been said that Egypt is the home of the comic strip.But for Egyptians,pictures still had magic power. So they did not try to make their way of writing simple.The ordinary people could not understand it.By the year 1000 BC,people who lived in the area around the Mediterranean Sea had developed a simpler system of writing. The signs they used were very easy to write,and there were fewer of them than in the Egyptian system.This was because each sign,or letter,represented only one sound in their language.The Greeks developed this system and formed the letters of the Greek alphabet.The Romans copied the idea and the Roman alphebet is now used all over the world.These days,we can write down a story,or record information,without using pictures.But we still need pictures of all kinds:drawing,photographs,signs and diagrams.We find them everywhere:in books and newspapers,in the street,and on the walls of the places where we live and work.Pictures help us to understand and remember things more easily,and they can make a story much more interesting.Pictures of animals were painted on the walls of caves in France and Spain because______.A:the hunters wanted to see the picturesB:the painters were animal loversC:the painters wanted to show imaginationD:the pictures were thought to be helpful

共用题干Cloning(克隆):Future Pertect?1 A clone is an exact copy of a plant or animal produced from any one cell.Since Scottish scientists reported that they had managed to clone a sheep named Dolly in 1997,research into cloning has grown rapidly.In May 1998,scientists in Massachusetts managed to create two identical calves(牛犊)using cloning technology. A mouse has also been cloned successfully.But the debate over cloning humans really started when Chicago physicist Richard Seed made a surprising announcement:"We will have managed to clonen a human being within the next two years."he told the world.2 Seed's announcement provoked a lot of media attention,most of it negative.In Europe, nineteen nations have already signed an agreement banning human cloning and in the U.S. the President announced:"We will be introducing a law to ban all human cloning and many states in the U.S. will have passed anti-cloning laws by the end of the year."3 Many researchers are not so negative about cloning.They are worried that laws banning human cloning will threaten important research.In March,The New England Joumal of Medicine called any plan to ban research on cloning humans seriously mistaken.Many researchers also believe that in spite of attempts to ban it,human cloning will have become routine by 2010 because it is impossible to stop the progress of science.4 Is there reason to fear that cloning will lead to a nightmare world?The public has been bombarded(轰炸)with newspaper articles , television shows and films , as well as cartoons.Such information is often misleading,and makes people wonder what on earth the scientists will be doing next.5 Within the next five to ten years scientists will probably have found a way of cioning humans.It could be that pretty soon we will be able to choose the person that we want our child to look like.But how would it feel to be a clone among hundreds,the anti-cloners ask. Pretty cool , answer the pro-cloners(赞成克隆的人). Within ten years scientists will probably have______.A:the nucleus of a cellB:cloned human beingsC:a human being in two yearsD:a law to ban human cloningE:a report on human cloningF:heavy media coverage

At that rate,a lake may warm by a full degree Celsius in just 10 years?That difference may seem imull一you might not even notice it in your bath.But in a lake,slightly warmer temperatures could mean more algae(水藻),and algae can make the lake poisonous(有毒的)to fish.The study shows that in some regions,lakes are warming faster than the air around them.This is impor- tant because scientists often use measurements of air temperature to study how Earth is warming.By using lake temperatures as well,scientists can get a better picture of global warming.The scientists say data on lakes give scientists a new way to measure the impact of climate change around the world.That’s going to be useful,since no country is too big or too small to ignore climate change.Scientists aren't the only ones concerned、 Everyone who lives on Earth is going to be affected by the rapid warming ofthe planet.Many world leaders believe we might be able to do something about it,especially by reducing the amount of greenhouse(温室)gases we put into the air.That’s why the United Nations started the F'ramework Convention on Climate Change,or UNFCCC. Every year the convention meets,and representatives from countries around the world gather to talk about climate change and discuss global solutions to the challenges of a warming world.Scientists have been keeping records of lake temperatures for over 30 years.A:Right B:WrongC:Not mentioned

共用题干Electronic MailDuring the past few years,scientists all over the world have suddenly found themselves pro-ductively engaged in task they once spent their lives avoiding-writing,any kind of writing,but particularly letter writing. Encouraged by electronic mail's surprisingly high speed,convenience and economy,people who never before touched the stuff are regularly,skillfully,even cheerfully tapping out a great deal of correspondence.Electronic networks,woven into the fabric of scientific communication these days,are the route to colleagues in distant countries,shared data,bulletin boards and electronic journals.Any-one with a personal computer,a modern and the software to link computers over telephone lines can sign on.An estimated five million scientists have done so with more joining every day,most of them communicating through a bundle of interconnected domestic and foreign routes known col- lectively as the Internet,or net.E-mail is starting to edge out the fax,the telephone,overnight mail,and of course,land mail.It shrinks time and distance between scientific collaborators, in part because it is conven- iently asynchronous(异步的)( Writers can type while their colleagues across time zones sleep; their message will be waiting.).If it is not yet speeding discoveries,it is certainly accelerating communication.Jeremy Bernstein,the physicist and science writer,once called E-mail the physicist's umbilical cord(脐带).Later other people , too , have been discovering its connective virtues. Physi-cists are using it;college students are using it;everybody is using it;and as a sign that it has come of age,the New Yorker has celebrated its liberating presence with a cartoon-an appreciative dog seated at a keyboard,saying happily,“On the Internet,nobody knows you're a dog.” How is the Internet or net explained in the passage?A: Electronic routes used to fax or correspond overnight.B: Electronic routes used to read home and international journals.C: Electronic routes waiting for correspondence while one is sleeping.D: Electronic routes connected among millions of users home and abroad.
