3．The question of （61）who invented the computer cannot be answered with a single name．Throughout history，many different people have helped in the development of this （62）valuable（value） machine．
It could be said that the first computer（63）that could store programs was the 1949 Electronic Delay Storage Automatic Calculator．It （64）was created（create） by Maurice Wilkes．From this point forward，many developers helped to make various types of computer．
Twenty years later，many skilled （65）inventors（invent），including Bill Gates，Steve Jobs，and Steve Wozniak did much to develop personal computers in the form of PCs and Apples．By （66）the 1990s，ownership of PCs became common as production grew （67）less expensive（expensive） than before．Also，with the development of technology，the size of these machines became smaller so that they could be used in homes（68）easily（easy）．
There is no doubt （69）thatthere are so many people who helped to develop the computer．There are even legal battles（斗争） over who should be considered as the primary ones．As a matter of fact，it is their joint（共同的） efforts that lead to the development of（70）what we call the most useful machine today．

2．Not that Charlie's own life was easy！…Such training was common in acting families at this time，especially when the family income was often uncertain．（71）Unfortunately his father died，leaving the family even （72）worse off，so Charlie spent his childhood looking after his sick mother and his brother．By his teens，Charlie had，through his humor，become one of the most popular child actors in England．He could mime and act the fool doing （73）ordinaryeveryday tasks．No one was ever（74）bored watching him--his subtle acting made everything（75）entertaining．
…Tony（76）approached Julia，touched her shoulder and kissed her on （77）the cheek!She stepped back appearing surprised and put up her hands，as if（78）in defence．I guessed that there was probably amajor（79）misunderstanding．Then Akira Nagata from Japan came in smiling，together with George Cook from Canada．As they were introduced，eorge reached his hand out to the Japanese student．Just at that moment，however，Akira bowed so his nose touched George's moving hand．They both （80）apologized-another cultural mistake!

1．California is（1）the third largest state in the USA but has the largest population．It also has the（2）distinction of being the most multicultural state in the USA，（3）having attracted people from all over the world．The customs and languages of the immigrants（ 4）live on in their new home．This diversity of culture is not surprising when you know the history of California．
Cloning has two major uses．Firstly，gardeners use it all the time to produce （5）commercial quantities of plants．Secondly，it is valuable for research （6）on new species．Cloning plants is straightforward （7）while cloning animals is very complicated．It is a difficult task to （8）undertake．Many attempts to clone mammals failed．But at last the（ 9）determination and patience of the scientist（10）paid off in 1996with a breakthrough-the cloning of Dolly the sheep．

20．Read this book，and you can __________ many words and phrases used by native English speakers．（　　）

19．Animals are more like us than we ever imagined．They feel pain，they experience stress，they show affection，excitement and love．All these findings have been made by scientists in recent years and such results are beginning to change how we view animals．
Strangely enough，some of this research was sponsored by fast food companies like McDonald's and KFC．Pressured by animal rights groups，these companies felt they had to fund scientists researching the emotional and mental states of animals．
McDonald's，for instance，funded studies on pig behavior at Purdue University，Indiana．This research found that pigs seek affection and easily become depressed if left alone or prevented from playing with each other．If they become depressed，they soon become physically ill．Becauseof this，and other similar studies，the European Union has banned the use of isolating pig stalls from 2010．In Germany，the government is encouraging pig farmers to give each pig 20 seconds of human contact a day，and to provide them with toys to prevent them from fighting．
Other scientists have shown that animals think and behave like humans．Koko，the 300-pound gorilla at the Gorilla Foundation in Northern California，for instance，has been taught sign language．Koko can now understand several thousand English words，more than many humans who speak English as a second language．On human IQ tests，she scores between 70and 95．
Before such experiments，humans thought language skills were absent from the animal kingdom．Other myths are also being overturned，like the belief that animals lack self-awareness．Studies have als shown that animals mourn their dead，and that they play for pleasure．
These striking similarities between animal and human behavior have led some to ask a question："If you believe in evolution，how can't you believe that animals have feelings that human beings have？"
Until recently，scientists believed that animals behaved by instinct and that what appeared to be learned behavior was merely genetically-programmed activity．But as Koko，the gorilla shows，this is not the case．In fact，learning is passed from parents to offspring far more often than not in the animal kingdom．
So what implications does this knowledge have for humans？Because of this，should we ban hunting and animal testing？Should we close zoos？Such questions are being raised by many academics and politicians．Harvard and 25other American law schools have introduced corses on animal rights．Germany，meanwhle，recently guaranteed animal rights in its constitution-the first country to do so．

32．McDonald's and KFC give money to support scientists to do research on animals．BecauseC．

18．With the development of science and technology，the research of human genes is playing more and more important part in our daily life．Sometimes it is a hot topic drawing more and more attention．
Gene technology can cure serious diseases that doctors at present can almost do nothing with，such as cancer and heart disease．Every year，millions of people are murdered by these two killers．But if the gene technology is used，not only these two diseases can be cured completely，bringing happiness and more living days to the patients，but also the great amount of money people spend curing their diseases can be saved，therefore it benefits the economy as well．In addition，people can live longer．
Gene technology can help people to give birth to more healthy and clever children．Some families have hereditary diseases and their children will for sure have the family disease，which is a great trouble for these families．In the past，doctors could do nothing about them．But gene technology can solve this problem perfectly．The scientists just need to find the wrong gene and correct it，and a healthy child will be born．
Some people are worrying that the gene research can be used to clone human beings in large quantities．In the past few years，scientists have succeeded in cloning a sheep； therefore these people predict that human babies would be cloned．But I believe cloned babies will not come out in large amounts，for most couples in the world can have babies in a very normal way．Of course，the governments must take care to control gene technology．

17．My mother lived in the countryside and was upset about the snakes．She made a（61）complaint（complain） to me and wanted me to help her get rid of them．This was a chance for me to distinguish（62）myself（I） by inventing something（63）merciful（mercy） to catch snakes but not harm them．
At （64）the beginning，I checked if there were any products （65）that might help me，but there only seemed to be some powders designed to kill snakes．So I had to find out a new way．I set out（66）to research（research） the habits of the snakes，then I decided （67）onthree possible ways：firstly，removing their habitat； secondly，attracting them into a trap； thirdly，cooling them．I（68）chose（choose） the last one．I used the（69）frozen（freeze） bowl to make the snakes（70）inactive（active），and then collected them．Then next day we released them into the wild．
