]BDr. Dian Fossey，one of the world's leading women scientists，had a remarkable career.The work she devoted her life to protecting and studying the mountain gorillas (大猩猩) of Africa—has proved highly effective and has resulted in the steady (平稳的) increase of this most endangered great apes.Fossey made her first trip to Africa in 1963.Three years later，she returned to Africa to begin a longterm study of the mountain gorillas.She set up camp in the Democratic Republic of Congo but moved to Rwanda because of political reasons in 1967.She established her “Karisoke”Research Centre camp on September 24，1967.Fossey's aims were to study gorilla ecology (生态学) and social organization.She found that in order to achieve this，she needed to recognize individual gorillas，which required that the gorillas get used to her presence (出现)．By copying gorillas' behaviour and sounds，Fossey began to gain their trust，and in 1970 an adult male gorilla she had named “Peanuts” reached out to touch her hand.Close observations over thousands of hours enabled Fossey to gain the gorillas'trust and bring forth new knowledge about their behaviour.Stories and photographs of her work were published in National Geographic Magazine and elsewhere.In 1977，one of Fossey's favorite gorillas，Digit，was killed by poachers and she established the Digit Fund to help raise money for gorilla protection efforts in the same year.On December 26，1985，Fossey was murdered while going back to her house in Karisoke.Her body was discovered near the research centre.Most probably，Dian Fossey had been killed by the poachers she'd fought against.On her tombstone (墓碑) “No one loved gorillas more...”In 1988，the life and the work of Fossey were made into a movie based on her story.【语篇解读】本文是一篇人物传记。

Yes，there is.Please follow the 3 basic steps below.Relax and breathWhether it's a business meeting or a first date the first thing you must do in order to communicate is to relax.When you relax you are in control.You control your reactions and your reactions do not control you.Breathing is central to relaxation.Take a few deep breaths and your body will begin to be more at ease.This will help you apply what you already know about how to communicate well.Think and you will be preparedHave you ever heard the old saying “think before you speak”？Well，it is true.By thinking ahead about how the conversation might flow you will be better prepared，more at ease and more confident.Follow the flow of the conversationIf you are uncomfortable，being silent will only make it worse and make the other person uncomfortable as well.So when all else fails，follow through with small talk until a common topic appears.A good way to keep a conversation going is to ask the other person questions.People love to talk about themselves and if you do this they will leave the conversation thinking very highly of you.Learning good communication skills is not something out of reach.If you make an effort，you will succeed.1．Which of the following is the best title of the passage?A．How to Communicate with Anyone You MeetB．Preparation and ConversationC．Personal Attention and CommunicationD．How to Begin Your Conversation Effectively2．If you want to talk with others successfully，the most important thing you should do is________．A．to keep calm and relax yourself fullyB．to take as many deep breaths as possibleC．to make a good preparation for the conversationD．to follow the flow of the conversation3．Why does relaxation play an important part in your good communication?A．Because it can help you keep excited and react quickly in the communication.B．Because it will help you organize good sentences for your communication.C．Because it can help you put your communication skills that you know into use.D．Because no one likes to communicate with a nervous person.4．If you feel uncomfortable，you'd better________．A．keep silence in order to give the chance of speaking to othersB．speak freely so as to run across the topic you likeC．talk small things until you find a topic you both likeD．ask questions which you are interested inB(2019·福建省莆田市第二十四中学高二上学期期末) It seems that the great desire among the young is to be popular.The desire to be popular can force you into looking and acting like everyone else.You can lose yourself in a sea of identical hairstyles and thinking styles.I was forced to think about popularity not too long ago in a talk I had with my daughter.Margy had to change schools when my busy work schedule made it necessary for me to move houses.I suppose that, for a girl in her teens, entering a new school is like spending a season alone in the tropical jungles.At least that's how Margy found it at first.However, as the school year drew to a close, one student after another came to her.I told Margy that I would have been more concerned if she had been an instant social success in her new school.Nobody can please everyone.If you try to do so, you will find values as lasting as soap bubbles blown into the air.Some teenagers claim they want to dress as they please.But they all wear the same clothes.They set off in new directions in music.But somehow they all end up listening to the same record.Their reason for thinking or acting in a certain way is that the crowd is doing it.They have come out of their cocoon into a larger cocoon.I know that it has become harder for a young person to stand up against the popularity wave.Our way of life makes a young nonconformist stand out like a Martian.These days there's a great barrier for the young person who wants to find his or her own path.But the barrier is worth climbing over.You may want to listen to classicalmusic instead of going to a party.Well, go to it.Be yourself.Popularity will come with the people who respect you for who you are.That's the only kind of popularity that really counts.5．Why was the author worried about his daughter's popularity in her new school?A．She might find no true friends.B．She would ignore her academic performance.C．She had no idea of her own.D．She might betray her true self.6．What does the author think of most teenagers?A．They're afraid of getting lost in life.B．They lack the courage to be truly different.C．They have difficulty understanding each other.D．They find it hard to gain popularity as expected.7．What is the probable meaning of the underlined word “nonconformist” in Paragraph 4?A．Someone who behaves in his own way.B．Someone who desires popularity greatly.C．Someone who cares about others' opinion.D．Someone who wants to please others.Ⅱ.语法填空She looks like any other schoolgirl，freshfaced and full of life.Sarah Thomas is looking forward to the challenge of her new Alevel course.But unlike her school friends，16yearold Sarah is not spending halfterm 1.________(rest)．Instead，she is earning￡6，500 a day as 2.________model in New York.Sarah 3.________(tell)that she could be Britain's new supermodel，earning a million dollars in
