痰湿咳嗽的特点是（）

A.痰黄咯吐不爽

B.痰中带血

C.痰粘腻稠厚成块

D.痰少粘连成丝

E.痰稀薄成水样

答案

参考答案：C

解析：痰湿咳嗽，湿邪困脾，脾不健运，化湿生痰，上渍于肺，故痰多粘腻，稠厚成块。

实验题

实验1：使实验中不同灯泡内气体压强均为0.1atm，钨丝长度相同但横截面积不同，通电后，维持2400K的恒温，则实验得到的维持这一温度所需电流以及灯丝的平均使用寿命如下表所示．

实验2：在灯丝粗细均为25μm的相同灯泡内加入质量不同的惰性气体，从而改变灯泡内部的压强，且使钨丝的温度保持在2400K，则当灯泡内气体的压强从0.1atm增大到0.5atm时，灯泡的平均使用寿命从800h延长到6000h，超过0.5atm后，灯泡平均使用寿命递减．

根据上述实验回答下列问题：

（1）在相同的灯丝温度下，下列灯泡中钨丝平均使用寿命最长的是__________。

A．50 μm粗细的灯丝并充有2.5atm的惰性气体

B．100 μm粗细的灯丝并充有0.4atm的惰性气体

C．150 μm粗细的灯丝并充有0.1atm的惰性气体

D．150 μm粗细的灯丝并充有0.4atm的惰性气体

（2）实验1中，若灯丝粗细为75 μm，并且灯丝的发热电阻为500Ω，要保证该灯泡的平均使用寿命为2400h，则加在该灯泡两端的电压不能超过__________伏．

问答题

On the advice of his accountant, Mat registered a private limited company to conduct his small manufacturing business in January 2010. One of the reasons for establishing the company was to avoid liability for potential losses. The initial shareholders of the company were Mat, his wife Mary, and her father Norm, who each took 1,000 shares in the company, each with a nominal value of ￡1. The accountant explained that they did not have to pay the full nominal value of the shares at once, so they each paid only 25 pence per share taken, with the result that they still owed the company a further 75 pence per share to be paid at a later date.When the company was established it became apparent that it needed to borrow money from a bank to finance an expansion in production. To that end Oop bank plc lent the company ￡20,000 secured by a fixed charge against the land Mat had previously transferred to the company, with an additional personal guarantee from Mat for any further debts owed by the company to the bank.Unfortunately the business has not proved successful and Mat and the other shareholders have decided that it is better to liquidate the company rather than run up any more debts. The current situation is that the company’s land is worth ￡20,000 and it has further assets to the value of ￡7,750, but it has debts to business creditors of ￡10,000 and owes the bank a further ￡10,000 on its bank overdraft.Required:Explain the rights of the various creditors and the potential liability of Mat, Mary and Norm. (The actual costs of winding up may be ignored.) (10 marks)
