在 $\Delta ABC$ 中，点 $M$ 是 $BC$ 的中点，点 $N$ 在 $AC$ 上且 $\stackrel{\rightharpoonup }{AN}=2\stackrel{\rightharpoonup }{NC}$ ， $AM$ 交 $BN$ 于点 $P$ ，设 $\stackrel{\rightharpoonup }{AP}=\lambda \stackrel{\rightharpoonup }{AM}$ ，则 $\lambda$ 的值为（    ）

下列实验操作不能达到其对应目的是（   ）

序号	实验内容	实验目的
A	在淀粉溶液中加入稀硫酸，水浴加热，一段时间后，再加入少量新制的氢氧化铜悬浊液并加热	验证淀粉已水解
B	向2 mL甲苯中加入3滴KMnO4酸性溶液，振荡；向2mL己烷中加入3滴KMnO4酸性溶液，振荡	证明与苯环相连的甲基易被氧化
C	在苯酚溶液中加入溴水	用FeCl3溶液可检验苯酚是否完全反应
D	用苯与浓H2SO4和浓HNO3制备硝基苯，将产物倒入NaOH溶液中，静置，分液	除去硝基苯中混有浓H2SO4和浓HNO3

      Computers can help many workers. They can also help thieves.
      There was one thief who worked in a bank of the United States. He paid for everything he needed by check (支票). Then he told the computer not to take any money from his account for the checks he wrote. The bank's computer did what he said. And it did not take any money from his bank account. One day the computer broke down. People had to do the computer's work. They soon found out what was happening.
      Another thief, who worked for a bank saw people filling in deposit forms (存款单). Many of these people did not know their account numbers, so they wrote only their names on the forms. They left empty places for their account numbers. The thief wrote his own account number in this place. When the computer read these forms it looked only at the account numbers. It did not look at the customers' names. It paid the money on these deposit forms into the thief's account .                           
       Then there was the bank worker who told the bank computer to take ten cents off every customer's account each month and put it into his own account. For a long time the bank's customers did not notice that they were losing ten cents every month. But then someone did notice and told the bank. That was the end of that little game!
