麻烦各位帮我翻译一下英文啦~~

1.为甚么星星会一闪一闪的?
因为我们看到星闪闪,这不是因为星星本身的光度出现变化,而是与大气的遮挡有关。
大气隔在我们与星星之间,当星光通过大气层时,会受到大气的密度和厚薄影响。大气不是绝对的透明,它的透明度会根据密度的不同而产生变化。所以我们在地面透过它来看星星,就会看到星星好像在闪动的样子了。
2.插头小常识
为什么电风扇、洗衣机、电冰箱等家用电器大多用三线插头?三线插头与三相插头有什么区别? 三相电器指三根不相同的火线,它们每两根线之间的电压都是380伏,一般用于动力系统,多见于工业用电。而家用电器一般采用单相电源供电,其三根线分别是火线、零线(中性线)和地线,火线和零线之间的电压是220伏,所以这不是三相电,它的插头和插座也不是三相插头和三相插座,地线为的是保障安全。
3.有一次,牛顿在实验室里聚精会神地做实验,连吃饭的时间也忘了。他的助手便拿了几个鸡蛋,送到实验室去,对牛顿说:“这里有几个鸡蛋,你自己煮来吃吧。”牛顿说:“好,谢谢你,请你把鸡蛋放在那里吧。”说完,他又埋头做实验。过了很长的时间,牛顿的肚子饿了,才想起还没吃午餐。于是,他随手拿了一个小锅,把鸡蛋放在锅里,往炉子上一放,又开始做起实验来。过了半个小时,牛顿做完了实验。这时,他才想起锅里的鸡蛋。他打开锅盖一看,里面没有蛋,只有一个怀表。牛顿大吃一惊,抬头一看,鸡蛋还在桌子上,可是桌上的怀表却不见了。原来牛顿太过专心做实验,结果把怀表当成鸡蛋来煮。
(*^__^*) 如果各位方便的话。。再顺便帮我弄一篇关于科技生活小知识的文吧~~~要有中英文哦~(*^__^*)
当然如果没有的话也没事的。。但是上面的翻译一定要帮我哦~~~一定会有重赏的~~~~~~~ 展开

1. Why the stars will flash flash it?
Because we can see stars sparkle, this is not because of the stars change their brightness, but with the atmosphere, blocking the.
Across the atmosphere between us and the stars, when the starlight through the atmosphere, they will receive the impact of atmospheric density and thickness. The atmosphere is not absolutely transparent, its transparency will be different according to the density difference. Therefore, we look at the stars on the ground through it, you'll see the stars as if flashing the same again.
2. Plug tips
Why are electric fans, washing machines, refrigerators and other household appliances are mostly three-wire plug to use? Three-phase three-wire plug and plug What is the difference? Three-phase electrical means three different firing line, they are each of the voltage between the two lines is 380 volts, are generally used for power system, prevalent in the industrial use of electricity. The household appliances generally use the single-phase power supply, the three lines are FireWire, zero line (neutral line) and ground, FireWire, and the zero-line voltage between 220 volts, so this is not a three-phase electricity, it plugs and sockets are not three-phase three-phase plug and socket is the ground for safety.
3. On one occasion, Newton concentrate in the laboratory experiments, even a meal time forgot. He then took an assistant several eggs, and sent to a laboratory to go to the Newton said: "There are a few eggs, you cook to eat." Newton said: "Well, thank you, would you please put all their eggs where the bar. "finished, he buried experiment. After a very long time, Newton's hungry, and he come not to eat lunch. So he readily took a pot, put eggs in pot to the stove for a while, they began to start experiments. After a half an hour, Newton finished the experiment. Then he remembered the pot of eggs. He opened the lid a look inside there are no eggs, only a pocket watch. Newton was shocked, looked up, eggs are still on the table, but the table pocket watch had disappeared. Newton too much to concentrate on the original experiment, the results of the pocket watch as eggs to cook.
