The science of physics today is as current as the morning newspaper. Indeed,as
a result of new advances in physics and their rapid application to inventions designed to satisfy man's wants, the world ?itself? has been changing rapidly. Space technology, industrial technology, and the technology of the home, the farm, the office, the bank, and the department store have all been revolutionized.
Clearly, every grown?up today would understand the world he lives in much better if he knew something about physics. Whether it be Congress(美國(guó)國(guó)會(huì)) voting huge sums of money for new ?warships,? space exploration, or atomic energy;the office staff learning to use a new computer;son Bobby wanting to know about going to the moon;or the housewife learning to operate a new electric stove physics seems to be everywhere.
Teachers in thousands of schoolrooms in America are trying to communicate some of the excitement and importance of these new developments to their students.
They know that some of their eager students will someday be scientists and will them selves then contribute(貢獻(xiàn)) to the development of new knowledge or its application to new things.
But in any case, they can be sure that if they bring a knowledge of science(any science) to their students in meaningful and stimulating ways, they have contributed much to helping each one live a more meaningful life.
1.The application of new advances in physics to inventions ________ .
A.may solve all the problems in teaching
B.can help people understand the meaning of life
C.is intended to meet people's needs
D.makes people understand the voting rules of the Congress
2.According to the passage, many American teachers are making efforts to do all of the following EXCEPT ________.
A.stimulating their students' curiosity in physics
B.making their students understand the importance of physics
C.giving their students the information of new advances in science
D.creating excitement about physical education among their students
3.The word “themselves” in the third paragraph refers to ________ .
A.some of the eager students B.the students in the classroom
C.the teachers giving lessons D.all the scientists in physics
4.The first two paragraphs of the passage mainly tell us about ________ .

1.這是一道細(xì)節(jié)題。第一段第二句話講述了物理學(xué)的發(fā)展和發(fā)明成果的快速運(yùn)用滿足了人們的需要。wants與needs同義。答案為C。
2.這是一道細(xì)節(jié)題。從第三段第一句話可知,美國(guó)的教師們對(duì)物理學(xué)新發(fā)展的重要性和一些令人激動(dòng)的事與學(xué)生們進(jìn)行交流。選項(xiàng)D的意思是“在學(xué)生中創(chuàng)造(creating)物理教育的激動(dòng)人心的事!贝鸢笧镈。
3.這是一道猜詞義題。在第三段最后一句話中,賓語(yǔ)從句的主語(yǔ)是“some of their eager students句中賓語(yǔ)的反身代詞“themselves”則應(yīng)該指主語(yǔ),由此可以得出答案。答案為A。
4.這是一道主旨題。短文的前兩段主要講述了物理學(xué)在人們生活中的應(yīng)用。由于物理學(xué)新的發(fā)展和它的發(fā)明成果的快速應(yīng)用,使世界發(fā)生了快速的變化。空間技術(shù)、工業(yè)技術(shù),以及在家庭、農(nóng)場(chǎng)、辦公室、銀行、商店等方面的應(yīng)用技術(shù)都發(fā)生了革命。從國(guó)會(huì)成員到每一個(gè)普通百姓只要懂得一些物理知識(shí),生活就會(huì)更好。物理學(xué)似乎無(wú)處不在。答案為B。

answered through an experiment.Here are some examples of questions:Does the amount of light have an effect on how fast plants grow?How much salt is in different kinds of cookies sold at the store? Why does the sky change color at different times of the day?
How much time do I have before the scienc fair?
A great science project always includes an experiment. Make sure that your question can be answered throuth an experiment, Here some examples of questions,Does the amount of light have an effect on how fast plants grow? How much salt is in different kinds of cookies sold at the store? Why does the sky change color at different times of the day?
