【正文】 somebody, anybody, everybody, nobody。 ?Conversely, substances of small resistivity are good conductors. ?This device consists in fact of five parts. ?Who made the first generator in the world, then? ?An increase in temperature, though, tends to make a gas expand. ?Roughly speaking, microwaves are radio waves whose wavelength is less than 30 cm. ?Velocity, we have noted before, is a vector quantity. ?A few kiloohms will, I believe, be enough. 常用的插入語有： 一般來說， general speaking, 更為重要的是， more important, 最為重要的是， the most important, 人們斷言， it has been claimed, 我們將會看到， it will be noticed, we can see, 我認為， I believe, 確實， it is true, 我們認為， we think, 倒裝句 ?Among the experiments to be conducted is a search for Martian life ?In the drawing are another pair of similar right triangles. ?Before long, out came the water. ?There exists a very important relationship between current, voltage and resistance. ?There has been developed a method for producing vastly more powerful rays. ?Orbiting the nucleus are negatively charged particles called electrons. 英譯漢練習(xí) 1. These forces act on the electrons able to move freely within the wire. 2. The more the spring is stretched, the greater is the force necessary to stretch it. 3. Neutron has a mass slightly larger than that of a proton. 4. In the measurement of time intervals much shorter than a second, the decimal system is used. 5. A method of timing accurate to millionths of a second is necessary. 6. An effect similar to postdeflection（后偏轉(zhuǎn)） acceleration could, it is true, be achieved by increasing the voltage on the second anode（陽極） . 7. Figure 35 pictures an addition of velocities that our mon sense tells us must be right. 8. Electrical inventors who followed Edison did not have to experiment with the substances which, he had found, would not work. 9. For several years after radio was invented it existed in the form of radio telegraphy. Then came radio telephony. 10. Also plotted on Fig. 1 are some allowable operating bands for several systems. 11. There is thus set up a transverse strain（應(yīng)力） in addition to the longitudinal（縱向的） strain. 12. Only when x is 5 is it true that 3x+12=27. UNIT 4 ? take: 需要， It takes two men to do this. 做這
