1. Translate the following into Chinese.
(1)A bipolar junction transistor (BJT) is a three-layer silicon (or germanium) device
consisting of either two p- and one n-type layers of materials (pnp) or two n- and one p-type
layers of materials (npn).
(2)Since the emitter follower has a high input impedance and a low output impedance, its
voltage gain is less than unity and the power gain is normally lower than that obtained from other
configurations.
(3)The current in a reverse-biased diode is small (typically 10-8 A for silicon) and
approximately independent of voltage until the breakdown region at high reverse voltages is
reached.
(4) Most integrated circuits provide the same functionality as “discrete” semiconductor
circuits at higher levels of reliability and at a fraction of the cost.
(5) Vision is well developed in most snakes, but many burrowing snakes are virtually blind.
(6) Working out regularly may make you smarter now and lessen the possibility that you
will lose brain function as you age.
(7) They work out a new method by which production has now been rapidly increased.
答案：
1双极结晶体管(BJT)是一种三层硅(或锗)器件，由两个p型和一个n型层的材料组成(pnp)或两个n和一个p型组成(npn)。
2由于发射器的输出端具有较高的输入阻抗和低输出阻抗，因此它的输出阻抗很低 电压增益小于统一，功率增益通常低于从其他增益 配置
3反向偏置二极管的电流很小(通常为硅的10的负8次幂) 近似于外加电压，直到高反向电压的击穿区域 达成。
4大多数集成电路提供与“分立”半导体相同的功能 电路的可靠性高，成本低。
5大部分的蛇视觉很好，但是许多洞穴的蛇失明。
6定期锻炼可以让你变得更聪明，减少你 随着年龄的增长，会失去大脑功能的可能性（风险）。
7他们使用一种工艺，是产品被快速生产。
2. Translate the following into English.
(1) 模拟放大器根据设定的放大倍数对模拟电压或电流信号进行放大，以推动负载
工作。
(2) 放大器的增益就是放大倍数，用于表示放大器对小信号的放大能力。
(3) 很多实际应用系统中的放大电路都通过级联多级放大器来提高放大倍数。
(4) 模拟电路用于处理在0 伏到电源电压之间任意变化的信号。
(5) 航天员同其他任何人一样，会随身把微生物(microbes) 携带到他们去的任何地方。
(6) 研究睡眠的长远目标就是对入睡和清醒两者之间的联系予以全面说明。
(7) 已下令将目前在太空实验室里的研究人员送回来。
1The analog amplifies according to the amplification factor set to amplification the analog voltage or current signal drive the load work
2 The gain of an amplifier is a magnification of the amplifier's ability to magnify a small signal
3,Amplifiers are amplified by cascaded multistage amplifiers in many practical applications
4 The analog circuit is used to signal any change between zero and voltage
5The astronauts will carry the microbes anywhere they go like anyone else。（不够地道）
The astronauts， like anyone else，will carry the microbes anywhere they go。
6The long-term goal of studying sleep is to fully explain the link between sleep and wakefulness
7The researchers have been ordered to return the researchers who are currently in the space lab
