英译汉
1.On the one hand, although the central bank does not make loans to enterprises and can not derive deposits directly, it controls the sources of commercial banks` money creation—the creation and supply of the monetary base; and on the other hand commercial banks` money creation through taking in deposits and granting loans is based on the central bank's monetary base.
一方面，尽管中央银行并不直接为企业发放贷款，也不能产生派生存款，但是中央银行却控制着商业银行创造货币的源泉——基础货币的供给和创造。另一方面，商业银行利用中央银行提供的基础货币，通过吸收存款和发放贷款来创造信用货币
2.Post- Keynesian school complement the theory of partial equilibrium and develop the theory of general equilibrium which stresses the interaction of both the commodity and the money market. The main viewpoint is as follows——A central bank adopts expansionary monetary policy, which will lead to the increase of money supply and further the fall of interest rates, which will stimulate investment; then the aggregate demand will increase, which will push up the total output; and finally income will rise.
后凯恩斯学派丰富了具备均衡理论并且发展了一般均衡理论，后者强调了商品市场和货币市场之间的相互作用。其主要观点如下——中央银行如若采取扩张性的货币政策，就会导致货币供给的增加，并由此促使利率水平的下降，而这将会刺激投资水平的提升，最终，总需求将会增加，总需求的增长会推动产出增长，最终收入水平将会随之上升。
3.Generally speaking , there is a relatively long-time lag between the adoption of monetary policy and the changes of the final targets of monetary policy, and the time-lag usually lasts 9 or 12 months. It would be too late if the central bank adjusts the monetary policy instruments after the change of the final targets of monetary policy
一般来说，从实施货币政策开始，到货币政策最终目标发生变化，这中间存在相对较长的时滞，通常时滞时间为9至12个月。如若中央银行在货币政策最终目标发生改变之后才开始调整货币政策工具可能就会太晚了。
简答题（Counter-measures of inflation （Policies concerning demand controlling)）
Tight monetary policy
The policy is squeezing money carried out by a central bank to raise the purchasing power of money by reducing the quantity of money in circulation. The concrete measures are as followings:
(1)Raising the discount rate and lending rate for the purpose of increasing the market interest rate.
(2)Selling government securities in the open-market to push up interest rates indirectly.
(3)Raising the required reserve ratio, which reduces the funds that commercial banks can loan and weakens the derivative ability of money so that money supply can decrease.
Tight fiscal policy
The policy includes increase of tax and reduction of government spending.
The tight fiscal policy will result in the increase of unemployment and the fall of output, and further an economic depression in the short run.

The question being discussed is very important. 4. You are welcome to a party which is to be given in our class at 7:4 5. You are welcome to a party to be given in our class at 7:45. 总结：以上做定语的那些短语就是英语语法中所说的分词，不定式的各种形式作定语。 1. 这些短语作定语应放在被修饰名词的后面。如果单独一个V-ing或V-ed形式作定语，则可以放在被修饰名词前面。 2. 分词作定语时，其动作应与全句动作同时发生。V-ing表示主动意义和正在做，V-ed表示被动意义。being done表示正在被做的。 3. 不定式作定语表示将要发生的，to be done表示将要被做的。 例句： 1. Goods imported from abroad are not always better than those made in China. 2.

1.This electron beam sweeps across each line at a uniform rate，then flies back to scan another line directly below the previous one and so on，until the horizontal lines into which it is desired to break or split the picture have been scanned in the desired sequence． 电子束以均匀的速率扫描每一行，然后飞速返回去扫描下一行，直到把被扫描的图像按所希望的顺序分割成行。 2.The technical possibilities could well exist，therefore，of nation-wide integrated transmission network of high capacity，controlled by computers，interconnected globally by satellite and submarine cable，providing speedy and reliable communications throughout the word 因此，在技术上完全可能实现全国性的集成发送网络。这种网络容量大，由计算机控制，并能通过卫星和海底电缆实现全球互联，提供世界范围的高速、可靠的通信。 3.Transit time is the primary factor which limits the ability of a transistor to operate at high frequency． 渡越时间是限制晶体管高频工作能力的主要因素 4.The intensity of sound is inversely proportional to the square of the distance measured from the source of the sound. 声强与到声源的距离的平方成反比。 5.The attenuation of the filter is nearly constant to within 0.5 dB over the entire frequency band． 该滤波器的衰减近于恒定, 整个频带内的变化在0.5 dB以内。 6.At present, the state of most semiconductor device technology is such that the device design and process technology must be supplemented by screening and inspection procedures, if ultimate device reliability is to be obtained and controlled． 目前, 大多数半导体器件的技术尚未十分完善, 以至若要获得并控制器件最终的可靠性, 就必须辅以筛选和检验, 以弥补设计和工艺技术之不足 7.Bandwidth of transistor amplifiers vary from about 250 MHz in the L band to 1000 MHz in the X band． 晶体管放大器的带宽在L波段约为250 MHz, 在X波段为1000 MHz。 8.The output of the differential amplifier is fed to the circuit’s output stage via an offset-compensation network, which causes the op-amp’s output to center at zero volts. The output stage takes the form of a complementary emitter follower, and provides a low-impedance output. 差动放大级的输出通过一个失调补偿网络与输出级相连, 目的是使运放的输出以0 V为中心。输出级采用互补的射极跟随器的形式以使输出阻抗很低 9.Because of the very high open-loop voltage gain of the op-amp, the output is driven into positive saturation (close to +V) when the sample voltage goes slightly above the reference voltage, and driven into negative saturation (close to-V) when the sample voltage goes slightly below the reference voltage. 由于运放的开环电压增益很高, 当取样电压略高于参考电压时, 输出趋向于正向饱和状态(接近+V)。当取样电压低于参考电压时, 输出趋向于负向饱和状态(接近-V)。 10.If the signal source were direct connected instead of capacitor coupled, there would be a low resistance path from the base to the negative supply line, and this would affect the circuit bias conditions. 如果信号源和电路不是用电容耦合而是直接相连，从基极到负电源线就会一个低阻通路，并且这将影响到电路偏置状态 11.The differential amplifier has a high-impedance (constant-current)“tail”to give it a high input impedance and a high degree of common-mode signal rejection. It also has a high-impedance collector (or drain) load, to give it a large amount of signal-voltage gain (typically about 100 dB). 差动放大极有一个高阻抗的“尾巴”（恒流源）以提供高输入阻抗和对共模信号的深度抑制，同时，它还具有一个高阻抗和集电极或漏极负载以提供高的信号电压增益（典型的数据是100dB). 12.On the other hand, a DC negative-logic system, as in Figure 3.6(b), is one which designates the more negative voltage state of the bit as the 1 level and the more positive as the 0 level. 另一方面, 如图3.6(b)所示, 把比特的较低的电压状态记为1电平, 较高的电压状态记为0电平, 这样的系统称为直流负逻辑系统。 13.For example, to represent the 10 numerals (0, 1, 2, …, 9) and the 26 letters of the English alphabet would require 36 different combinations of 1’s and 0’s. Since 25<36<26, then a minimum of 6 bits per bite are required in order to accommodate all the alphanumeric characters. 例如，要表示0～9十个数字和英文字母表中的26个字母，就需要0和1的36种不同的组合。因为25<36>26,
