领科国际部-初升高-面试口语题目

面试口语题目1.Tell me something about yourself?My name is LJW, and my English name is Karena. I am 16 years old and now I study in Pei Jia Bilingual School. I like playing the piano and doing some bakery in my free time. I think I am outgoing and bubbly. So I have many friends and I can get along well with most my classmates. Today I am very happy to attend the interview. And thank you for your attention.2. What do you want to be in the future?Actually, I haven’t a very clear idea about what to do in the future. But I am very interested in music, and I am quite skilled in playing the piano. So maybe in the future, I will dosomething about music, like a music teacher or pianist. But now, I really don’t have anexact answer. I hope in the study of senior high school, I can know what job fits memost, then I can make a final decision.3. Why do you want to study in our school? What interests you most of our school?The thing interests me most of your school is the activities. I think it is the main difference between an international school and a public school. From different activities, I candevelop my interest and enjoy my school life. What’s more, I know U-link is one of thetop international schools in Shanghai. Since I will go to Britain for further study, so thecourse set in your school A-level meets my needs very well. So I want to study in yourschool.4. What about your school life in Pei Jia?In the first two years, I think my school life is very interesting. We have lots of activities to take part in and have less school work. But I have to say my life in grade 9 is quitestressful, because we must handle the entrance examination. Every day we have largeamounts of homework.It’s terrible. I think it is one of the reasons why I want to go onstudy in an international school, because I think the traditional education just want toturn you into a test machine, I think it is meaningless.5. What are your favorite subject and least favorite subject?My favorite subject at school is PE, because it is the only time we can relax ourselves and leave behind the stressful school work. So I like it best. My least favorite subject isChinese. It’s not because I don’t like reading. Instead, I like reading very much.However, our Chinese teacher always asks us to recite the articles in the books. It is veryboring and time-consuming. I hope in the future, our teacher can share some interestingstories and books with us. I think it will be more meaningful.6. What are your strength and weakness?I think I am a person of good adaptability. I am a quick learner. And when I am in a newenvironment, I can adjust myself and fit into the new environment. Maybe it’s becauseI am very optimistic and open-minded. And my weakness is that I am a person of lessself-control. It shows in my daily life that I will forget time when I am watching TV orplaying computer. I need others to remind me. I know it is a very bad habit, so I amtrying best to work on it.7. What is the most important thing you have learned in your school?I think the most important thing I learned in my school is the organizational ability. I am themonitor of my class, so I have to help my teacher to take charge of some activities.What’s more, as a monitor, I should learn how to communicate with my classmates andteachers. It is also a good way to cultivate my interpersonal ability. I think these twoabilities are the most precious things I learned in my school, and I will carry them to myfuture life.8. Why do you think we should accept your application?First, my school performance is very good. Generally speaking, I can always rank the top 10 in any exams. Secondly, since I am the monitor of my class. So it helps me establish manygood qualities, such as responsibilities and organizational abilities. Finally, I have a widerange of interest. I am skilled in playing the piano and I can speak a little French. I thinkan international school may prefer the well-rounded students rather than those who areonly good at studying. If I can be one of the students in your school, I am sure I willshow my potential.9. Do you have any questions for us about our school?a. Do your school have Chinese courses?b.c. Are there any chances that we can experience the courses in UK or USA by the studentsexchange program?10. Who is the person you admire most?The person I admire most is Emma Watson. She gets famous because of the Harry Potter series at an early age. But she is still very modest. In school, she is an A-list student so sheenters the Brown University very smoothly. In her heyday, she stops her movie career tosupport feminism (the gender equality). I have watched the video of her speech in theUnited Nation HeforShe. It is really powerful and provoking. I think she is a very goodmodel for teenagers. That’s why I admire her the most.11. What is the most unforgettable experience in your life?The most unforgettable experience in my life is the Bungee jumping in New Zealand. Last winter vacation, I went to New Zealand for travel. And it was the first time I experience Bungeejumping. When I standing in the 40-meter plat. I was afraid and I hold the hands of thestaff firmly. And suddenly, they pushed me to the ground. So it happened out of myexpectation. I really wanted to hold something when I am falling, because I was veryfrightened. Finally, I got to the boat and I felt was safe again. But now, I really want totry it again and experience the feeling like flying.12. Where is the favorite place you have been to?The favorite place I have been to is Austria. As we all know, it is the home of music. Since I have a great passion for music, so when I step into the land, I feel really friendly andexcited. Austria is also famous for its beautiful scenery, we paid a visit to the mostbeautiful village in the world which is called Hallstatt. Many famous musicians comefrom Austria, such as Mozart,Schubert and so on. So it has a very unique sense to me.That’s why I like Austria the best.13. What is your favorite book/ film?My favorite book is the one called Anna Karenina. It is written by a Russian writer called Leo Tolstoy. The story of the book is mainly about the life of Anna. Anna is a woman whopursuit true love and happiness. But the man he fall in love with is hypocritical and cruel.Therefore, he made Anna heartbreak and finally kill herself in the train track. This bookshow us the indifference of old Russian society.14. If you have one million dollars, what will you do with it?First, I will spend most of the money to do some investments,like buying insurance and investing in stocks.You know,as it is temporary to have one million dollars,investing isan advisable choice so that I can make as much money as possible with thosedollars.Second, I want to keep some into my bank account. If one day I get badinvestments, I have a little chance to save it. Most importantly, I will donate somemoney to some charities. Because I know there are many people in the world aresuffering from hunger and disease.15. If you have a disagreement with your friend, what will you do to resolve it?First, If we insist on our opinion, then we should keep calm and be patient to explain our ideas.Because when you have conflicts冲突, it is very easy for us to get angry.Actually, we can also put ourselves into others’ shoes.

We can both keep our opinions because disagreements and conflicts are quite normal in daily life.16.

I didn’t do well in that test. Generally speaking, my usual performance can allow me to enterthe best key schools in Shanghai, but that test really gave me a shock. I can’t evenenter the least excellent key school by that grade. To be honest, I have no excuse forthis failure. But this time my second mock entrance test is quite good.23.
