1 阅读理解。 When a person passes through the customs (海关) between two countries, he would be questioned by a customs inspector (检查员). If a person brings in goods of great value, the inspector may ask him to pay taxes on them. Some people try to hide the valuables they have with them so that they will not have to pay these taxes. But customs inspectors are hard to fool. Inspector Joseph Koehler has worked for the US Customs Service for years. One day a group of passengers arrived on a flight from Belgium. Koehler took special notice of one of the women among them. At first he did not know what made him pick her out of them ― the woman"s baggage was made of a purse and two suitcases. She showed no sign of fear when Koehler opened them. Yet Koehler could not rid himself of the feeling that something was wrong. Suddenly he knew what it was. The woman was too tall. This woman"s height didn"t seem right somehow. Then it was found that the bottom parts of her shoes were filled with something. The inspector opened them. A handful of diamonds fell out on the floor. More jewels were found under a false bottom in one of her suitcases. Their total weight was 3,387 carats. It was one of the largest diamond hauls (缴获) ever made by the US Customs. 1. From the passage, we can know that Joseph Koehler _____. A. only asked the women passengers to pay taxes on the valuable goods B. had worked for almost one year in the US customs C. opened every passengers" package when they passed the customs D. found a false bottom in one of the woman"s suitcases 2. The underlined word "it" in Paragraph 4 refers to"_____". A. the tax the woman should pay B. the reason to pick the woman out C. the woman"s baggage D. the inspector"s duty 3. We can learn from the last paragraph that _____. A. the woman was fond of making jokes B. the jewels were of high quality C. Koehler made great contributions to US Customs D. US Customs are in great need of inspectors like Koehler 4. Which of the following statements is TRUE according to the passage? A. Koehler was attracted by the woman"s beauty. B. The woman made some changes to her baggage. C. The job of a customs inspector is dangerous. D. The jewels were damaged by the US Customs.

6 如图所示，长为L的木板A静止在光滑的水平桌面上，A的左端放有小物体B（可视为质点），一端连在B上的细绳，绕过固定在桌子边沿的定滑轮后，另一端连在小物体C上，设法用外力使A、B静止，此时C被悬挂着。A的右端距离滑轮足够远，C距离地面足够高。已知A的质量为6m，B的质量为3m，C的质量为m。现将C物体竖直提高2L，同时撤去固定A、B的外力。再将C无初速度释放，当细绳被拉直时B、C速度的大小立即变成相等，由于细绳被拉直的时间极短，此过程中重力和摩擦力的作用可以忽略不计，细绳不可伸长，且能承受足够大的拉力。最后发现B在A上相对A滑行的最大距离为。细绳始终在滑轮上，不计滑轮与细绳之间的摩擦，计算中可认为A、B之间的最大静摩擦力等于滑动摩擦力，取重力加速度g=10 m/s 2。（1）求细绳被拉直前瞬间C物体速度的大小v 0；（2）求细绳被拉直后瞬间B、C速度的大小v；（3）在题目所述情景中，只改变C物体的质量，可以使B从A上滑下来。设C的质量为km，求k至少为多大？
