_______________________________
_________________.
2.He wants to be called the ______.Yuan LongpingHe is known for his work withrice / in agriculturefarmer
3.What do these three great minds have in common?
Various answers are possible.
They are all passionate about what they do. / They are on fire for something. / They have all made important contributions to science and society. 1. This woman is one of the greatest scientists of all times. Even her name tells you that she likes science: a good scientist should want to find out answers and ask many questions —in other words they should be curious.Listening Text This woman was certainly curious. Together with her husband, she tried to learn the secrets of radioactivity. The couple were awarded the Nobel Prize for Physics in 1903. Eight years later, she received a second Nobel Prize for chemistry. 2. It is said that this English gentleman was sitting in his garden one day when suddenly he was hit by a falling apple. The story is probably not true, but this man did mention that he got one of his best-known ideas while watching apples fall from a tree. His name makes you think that he was not too interested in old things. He discovered the force of gravity, and he drew up a system of how objects move. His laws for motion are still used in physics today, at least in schools and universities. 3. Food is what sets this great mind on fire. Rice, to be exact. This great mind has spent most of his life looking for ways to help farmers grow more rice so that all of us will have enough food to eat. He is known as the father of modern rice, but because of his long friendship with all the farmers in China, he would rather be known as “the farmer”.Great mind No 4 I am on fire for environmental protection. I want to learn more about animals, plants and the earth in order to be able to find new ways to protect the environment. I believe that most people would help protect the environment if
they knew more about it. So I will try to educate people and teach them about the environment. I think this is very important because we must change our behavior if we want to save
our planet.
I am on fire for languages! I love learning English and I want to start learning Russian soon. I think that people should study foreign languages because they help us to communicate with people in other parts of the world and understand them better. Best of all, learning a language is useful if you want to travel, and may help you to find a good job in the future.Computer

Essential to protecting the ecological balance and environment; people can’t live without living things and medicine.Is the key to the progress of human being; it is chemical reaction that produce many new things.Widely used in many fields, such as medicine, industry and agriculture.You can’t learn physics or chemistry well without a good knowledge of maths. It is a tool in science and engineering. It is now an indispensable tool in many fields. It can settle all kinds of problems at a high speed and can help people work easily.PracticeSample dialogue:
J=Student S=Scientist
J: Hello, Dr Jones. Thank you for
coming to our school. My name is
Janet and I would like to ask you a few
questions.S: Hello, Janet, nice to meet you. I’m
happy to be here and I will try to
answer your questions. What would
you like to know?
J: Well, first of all, I would like to know
why you decided to study physics.
Why did you choose this field?S: Well, I’m very interested in the
universe and I have come up with a
theory that explains why there is
frozen water on Mars.
J: Can you explain why this is important?
S: Well, I’m very interested in this
because if there is water on Mars, there might also be life on other planets.
J: That’s really interesting. I also read
about your new invention. Could you
please tell me more about it?
S: Yes, I invented a wonderful machine
called a “water hunter” that I use to
look for water on other planets.J: How does it work?
S: Well, it’s not easy to explain, but the
machine can take pictures of planets
and search for water. By looking at
the pictures, I can tell whether there’s
water or not.J: I see. Do you think that there is life on
other planets?
S: Hmm…That’s a good question. I’m
not sure, but I think I would have to
say yes. It seems that people have
found ice on Mars, and if there’s ice,
there could also be life. Maybe not now, but at some time in
the future or past. I think that it would
be strange if the earth was the only
planet with life on it.
J: Thank you very much. I hope you will
enjoy your visit here at our school.
S: You’re welcome.Language Points1. be similar to 和…差不多，与…相似
